Humans will not 'migrate' to other planets, Nobel winner says

Humans will not 'migrate' to other planets, Nobel winner says
Nobel prize winner Michel Mayor says he idea of humans living on a nother planet is 'completely crazy'

Humans will never migrate to a planet outside of Earth's solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said Wednesday.

Mayor and his colleague Didier Queloz were on Tuesday awarded the Nobel Prize for Physics for their research refining techniques to detect so-called exoplanets.

"If we are talking about exoplanets, things should be clear: we will not migrate there," Mayor told AFP near Madrid on the sidelines of a conference when asked about the possibility of humans moving to other planets.

"These planets are much, much too far away. Even in the very optimistic case of a livable planet that is not too far, say a few dozen light years, which is not a lot, it's in the neighbourhood, the time to go there is considerable," he added.

"We are talking about hundreds of millions of days using the means we have available today. We must take care of our planet, it is very beautiful and still absolutely liveable."

The 77-year-old said he felt the need to "kill all the statements that say 'OK, we will go to a liveable planet if one day life is not possible on earth'."

"It's completely crazy," he added.

Using custom-made instruments at their observatory in southern France, Mayor and Queloz in October 1995 discovered what had previously only existed in the realm of science fiction—a planet outside Earth's solar system.

Mayor was a professor at Geneva University and Queloz was his doctorate student, when they made the discovery which started a revolution in astronomy. Since then over 4,000 exoplanets have been found in our home galaxy.

"It was a very old question which was debated by philosophers: are there other worlds in the Universe?," Mayor said.

"We look for planets which are the closest (to us), which could resemble Earth. Together with my colleague we started this search for planets, we showed it was possible to study them."

Mayor said it was up to the "next generation" to answer the question of whether there is life on other planets.

"We don't know! The only way to do it is to develop techniques that would allow us to detect life at a distance," he said.

No offense, but how often have scientists said something is "completely crazy" and then later we end up figuring out maybe the idea wasn't so crazy after all?

This sort of upset rarely happens by complete surprise, that is, it happens when someone discovers a way around the limitation, or the supposed limitation was based on speculation instead of experiment. Many are opinions, rather than tested facts. In this case, though, we've spent a century trying our best to find a loophole, experimentally and theoretically, without any better than speculative success. The chance of our finding one in the next century doesn't look good.

Even the closest star to us is about 4 light years away. This distance is very far. Like our Sun being a soccer ball in the end zone of a stadium in LA, Earth a grain of sand 100 yards away, Jupiter a golf ball in the parking lot, and Alpha Centuri another soccer ball 2000 miles away somewhere in Missouri.

The only scenario I can see where humans are actively colonizing planets of other systems would be for seeding the galaxy if we find it barren and want to preserve life. It'd be an incredibly difficult task and we would need to be at least a type 2 civilization but I can imagine future humans trying to do it 1000-2000 years down the line when they start transitioning to a type 3 civilization. Of course that's if we don't kill ourselves first.

We will visit other stars one day, when they travel CLOSE to us. The next star to travel close to us is about 10 million years from now, a star (Gliese 710) will travel close enough to get to it in less then a human lifetime.

He wasn't thinking about the stars that travel at different speeds and cross each others paths, over typically tens of millions of years or so.

Oct 09, 2019
Old men making grand statements that cement their entire life's work, nothing to see here.

Oct 09, 2019
We are closer to inhabiting other planets than many think. Genetic editing and artificial womb technology will allow a drone to land on a habitable planet and then 3d print the biology necessary for inhabiting that planet including food, grass, and animals.

Humanity isn't likely to be alive then.

https://en.wikipe...argument
it can be estimated that there is a 95% chance that the total number of humans N will be less than 20 × 60 billion = 1.2 trillion. Assuming that the world population stabilizes at 10 billion and a life expectancy of 80 years, it can be estimated that the remaining 1140 billion humans will be born in 9120 years. Depending on the projection of world population in the forthcoming centuries, estimates may vary, but the main point of the argument is that it is unlikely that more than 1.2 trillion humans will ever live on Earth.


Now this doesn't mean that humans will go away entirely. The statistical argument is that humans like we are have about 10,000 years to exist. What comes after could be trans-humans or degenerated back into apes.

Oct 09, 2019
Humans will not migrate to other planets. But our transhumanist descendants will. And they will take human species with them.

Oct 09, 2019
Never is a long time.
think of the advances weve made in 200 years, how fast things are moving now.
think of where we will be in 100 years, 1000, 100,000...
i have to think we will have, by then, overcome propulsion problems.
we will probably inhabit a few asteroids and turn them into spaceships.
and send them out toward the nearest stars.

Oct 09, 2019
Another thing is that we will not need habitable planets to survive in the long term. Asteroids have everything required.

look at the Nimitz UFO incident.
(video released by the DOD)
either we already have that tech, or China or Russia, does...
or ET is actually here, and if they are maybe they will share that tech :)

Oct 09, 2019
Google won't tell me, so I'm going to guess, what drove Mayor's search for exoplanets was finding a human inhabitable one. Isn't that the crazy quest of every man? Search for the perfect beauty knowing she's beyond your reach.

Oct 09, 2019
comicbook dreaming aside

if you resent this scientist's concept of pitiless reality?

what are you doing,
what physical effort are you making?
to change that reality?

Oct 09, 2019
Evidently, Nobel laureates do not watch much Star Trek. If they had, they would know that interstellar travel became routine sometime after 2160...

I've posted links to these patents here a couple times -- some think they're riddled with crack-pottery, while others say it's related to work China has been doing. The first link is for a craft and the second one is for the field generator the craft uses:
Craft using an inertial mass reduction device, and
Electromagnetic field generator and method to generate an electromagnetic field

Would the USPTO award these patents without first requiring examination of actual working devices?


Oct 09, 2019
This is an unbelievably pessimistic view. He has no idea what we might discover in the next few decades. In addition somewhat viable plans for generational ships have already been put forward. I do however agree with part of his view in that we can definitely do a better job of taking care of what we already have.

Oct 09, 2019
That same navy UFO patent scientist just filed a patent for a compact fusion reactor... pretty sure they've solved something major in mathematics that the wider scientific doesn't know about. It's probably something that was missed or an error was previously made

-link-

The patents could be a hoax or they could be real. It is basically impossible to find information on the patent filer and it would be fairly simple to spoof the assigners and other stuff. The devices themselves are all simple and hypothetical, actually developing them would require other technologies and concepts we don't have or understand. If you look at other patents with the same assigner you'll see they usually just let them expire out because they turn into nothing so if it is real I wouldn't really expect anything to come of it.

You do not need a working device or even any device at all to patent something.

"Now this doesn't mean that humans will go away entirely. The statistical argument is that humans like we are have about 10,000 years to exist. What comes after could be trans-humans or degenerated back into apes."

No, this is not true of the doomsday argument. You can't get past it just by saying we will evolve somehow into something different. That doesn't matter. Humans have continued to evolve since the very first homo sapiens. If its true that we will turn into something you call a "trans-human," as long as those are conscious beings (which is likely), they will be limited in number as if they were regular humans. The fact that you and I were not born as one of them would be extremely unlikely if there were going to be octillions of trans-humans in the far future. That's the point of the argument. If humans are destined to make it FAR FAR into the future, why were you so lucky/unlucky as to be born this early in human history? Its would be very unlikely, so probably not true.

Oct 09, 2019
I certainly do not agree. I think this is a a total lack of confidence maybe slightly arrogant view of likely future developments. Right now it may take along time but who is to say in 200 or 300 years. We are making gigantic strides now.

Oct 09, 2019
You don't even need a generational ship. You just need to travel fast enough. We need enough power to get very close to the speed of light and that's it! When that happens, time on the ship slows down and people can be made to live almost infinitely long near the speed of light without special "stasis" technology. To the people on the ship, as they approach the speed of light, it will appear to them as if space along their axis of travel is being compressed and the target star/planet can actually travel towards them faster than the speed of light (from their POV) if they get close enough to the speed of light. So we need either a generational ship or the ability to get close to light speed. Why would someone think neither of those will happen before humans become extinct? Oh yeah, the doomsday argument. If we were to spread across the galaxy, there would be a crazy number of humans in the future and we shouldn't have been born now...dang.

i think Robert Heinlein was prophetic when he wrote

soon after WWI, during all the aeronautics frenzy
idiots vying for the prizes offered for crossing the Atlantic first
would load up a small aircraft with their wife & kids
& fly off into the sunrise

really was no authority to stop them nor rescue them

i would wave good riddance to the unprepared comicbook "heroes"
if only they were fulfilling their destiny as Darwin Award Winners

unfortunately the odds are they had already reproduced
thanks to roofies & Southern Comfort
before Reality culls the silly asses from the gene pool

which means we are going to have scenes with the "mighty men" dragging their wives & children, kicking & screaming, aboard their rocketship "libertarian"

these days? they'll have radios

we will have the misery of listening to the stupes begging to be rescued
the wife & kids crying in the background
or, more likely?
silence...
the family already dead to conserve air for "mighty man's"survival

Oct 09, 2019
Humans will inevitably do whatever it takes to survive including whatever this guy in his infinite wisdom says we can't or won't. Space travel will be childs play to our descendants. Bury my bones on Rigel 7

Oct 09, 2019
Did a major human population ever completely leave a home territory to live elsewhere? Europeans didn't move to the Americas, they just sent some of their surplus people. If we devastate earth somehow, perhaps a significant fraction of the rich might relocate. But even if we were working within the solar system, how would the rich permit the spending needed to relocate a billion or more average people?

"Humans will never migrate to a planet outside of Earth's solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said Wednesday."

-He made the mistake of saying 'never'.

"That is the biggest fool thing we have ever done. The [atomic] bomb will never go off, and I speak as an expert in explosives."
Admiral William D. Leahy comment on the U.S. Atomic Bomb Project, to President Harry S. Truman in 1945

-However, humans may never leave the system because they are destined to be replaced by the AI singularity which will have no reason to go anywhere.
Humans will inevitably do whatever it takes to survive
-Thats right. Which is why we are going to continue replacing body parts with superior artificial organs until whatever makes us human is gone.

Oct 09, 2019
He is right (about you humans). I arrived here from Barnard's Star b in 1967, just in time for the Summer of Love. Unfortunately it's been downhill since then, and I curse the day I got stuck on this benighted backwater.

Oct 09, 2019
I am inclined to agree with this. Even if were ever to become possible we will NEVER find another planet as GOOD and WONDERFUL as the one we evolved in, after all the earth created us. So let us take care of this one first and for most.

Oct 09, 2019
I believe, it was Louis CK who jokingly said, when Europeans first journeyed across the American west, they arrived at their destination an entirely different group of people. It's in our DNA to try, and if we do make it, it may not just be as a different group, but perhaps, an entirely different species.

Oct 09, 2019
Never? And this person is a scientist?

Oct 09, 2019
In about 10 million years from now, a star (Gliese 710) will travel close enough to get to it in less then a human lifetime.


This will happen, and it was worth 2 negative marks, lol.

Oct 09, 2019
There are at least three different ways to turn this trick:

1. Asteroids made into generation ships. (By this I mean asteroids where humans live for generations while traveling to a new star.)
2. Human genetic materials transported to a new star, and engendered there.
3. Extremely high velocities utilizing relativistic effects to shorten perceived travel times for passengers.

1 and 2 are, IMHO, the most likely. And the question isn't whether we'll do them; it's when.

I will invoke Clarke's First law:
When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
I expect Mayor will get sick of hearing that after a bit.

Oct 09, 2019
I think his point is that we're wasting so much time, resources, imagination, and capital with these pie-in-the-sky fantasies of making a life on other planets when we need to immediately attend to the crises here at home.

Sure, continue research into advanced physics and propulsion technologies if that floats your boat, but to spend (eventually) trillions on putting humans on the moon (been-there-done-that), or terraforming Mars (really!), we should be looking at surviving the more immediate future of this beautiful planet we call home.

We may someday conquer the technological challenges of violating the known laws of physics, but here and now, there are much more important challenges.

I read an interesting discussion of travel over interstellar distances some years back.

It posited that if we send a ship now at present max speed, it will take X years to get there. A century from now, we send another ship at 10 times that initial speed with new technology, and it takes X/10 years to arrive. 5 centuries in the future, attainable speeds are now 10 times our last ship, so they will arrive in X/10/10 years. The pattern continues, so 5000 years from now, the colonists have already been firmly established for a millennium and greet each arriving starship in the reverse order in which they left earth.

Oct 09, 2019
Hence, if UFO aliens actually exist, they would be AI not biological.

Oct 09, 2019

In fact hundreds of stars (with their own solar systems) have crossed our path in the past 4 billion years. So who knows whether we got seeded with life multiple times from passing stars. heh

Oct 09, 2019
I'll bet that Michael Mayor knows far more than I about everything past our atmosphere, BUT it is awfully foolish to say "never" in most cases. While the average person cannot comprehend the incredible distances involved, technology never fails to be underestimated. We are mere decades into thinking about this problem, and our technology is accelerating, not slowing down. What might man be capable of in 50 years? 500? 1,000??

Not to mention, the idea of building a multi-generational, self-sustaining space-city is technology that we have right now, and could conceivably take man to exoplanets at stars multi-light years away. 100 years ago, very few people had cars, and the majority of people in the world never left a 50 mile radius from where they were born. NEVER has to be right forever, or else it is wrong. I think Mr. Mayor is wrong.

Oct 09, 2019
the notion that biological life has an expiration date but technology does not is completely false.
in fact humans outlive most of our technology.

Oct 09, 2019
I can't stand the whole light-speed limit argument. As if our current understanding of the universe and what's possible will remain the same forever

Oct 09, 2019
Very shortsighted. Never get to a far away world?This is like someone saying 2000 years ago we will never leave Europe because we don't have a boat fast enough to get to another land. And in 1492 Columbus probably said" And yet here we are"

Oct 09, 2019
One of the stupidest things a scientist can do is say "never".

We have absolutely no idea what the future may hold. Scientific understanding is growing at an ever increasing rate and AI is poised to drastically speed up the rate of scientific discovery. Who knows what we may discover in the next 10, 50, 100 years. Heck, a breakthrough in FTL could be made tommorow by a scientist researching something completely unrelated for all anyone knows.

Oct 09, 2019
We are all alive because of a process that occurs faster than the speed of light. The sun would not function without quantum mechanical tunneling of protons for fusion to occur which is instantaneous. Instantaneous is FTL. Einstein was famously wrong about quantum mechanics. "Spooky action at a distance" not only occurs, but it is also instantaneous, i.e., FTL. You might consider that Einstein made up for it by postulating the Einstein-Rosen Bridge, i.e., a wormhole, which might be another (or related) FTL option.

That is a valid point but if we followed that then we'd never accomplish anything because we'd always be waiting for better tech to come along. If we were able to travel at 1/10 the speed of light, which we will be capable of soon with technologies being worked on, we'd be able to reach Proxima Centauri within 40 years including time for acceleration and deceleration.

Oct 09, 2019
yep. there we are
& colonization of the New World resolved all the problems of the Old

that is why today, we are ruled by the mighty Empires of Portugal, Spain & Austria

yep. we as a species are too stupid to learn from our mistakes

let's just charge blindly ahead into the abyss
trampling into the muck,
everything we had once thought worth striving for

Oct 09, 2019
oh look all these comments that disagree... ok, it's ok to disagree but I agree with the man UNTIL we find a viable way to travel vast (with a big V) distances in an acceptable time... most have not the slightest idea of the word "vast" - this is for a human life of civilization, the very definition of "forever".
So, yes, get in shape, get your sh---i--t together because we ain't going nowhere !

Oct 09, 2019
Professor Mayor is a Pessimist. Perhaps he can't help himself when, after all, at his age he will probably never even go into LEO (the ISS). But there will be such things in the future as machines that can induce a deep sleep in humans that will also prevent their bodies from deteriorating/aging with their cells breaking down and dying. They will wake up when the ship arrives at their destination on a far-off planet in another galaxy, and their bodies will be in the same great condition as when they first went to sleep.
This technology is coming, as well as very fast space travel to the Stars and nice habitable planets. Science will MAKE it happen.
Everyone who is alive today will be gone to their just rewards, of course. But the children of the future will grow up to be the future settlers of new worlds - far away from this Solar System. They will be the frontiersmen of new worlds, and their curiosity will be enormous and insatiable.

Oct 09, 2019
If you have control over the perception of time, then the stars are as far away as you like them. Slow your perception of time down by a factor of 100,000,000 and you can cross the galaxy in a subject day.

Even if humans migrate to another planet, they won't survive for long. Darwin's principle of natural evolution tells us that all living things are in most original form when connected to the roots.

Cut the roots off, they start to perish unless adapted. Humans are earthlings - animals based only on earth. You can't survive for 10 years on ISS. Within six months of stay at ISS, bones and muscles start to decay.

I think what he's calling "completely crazy" is the notion that interstellar travel will ever be a viable alternative to maintaining a habitable environment here on earth.

Oct 10, 2019
@guptm
Guess what? Adaptation of both ourselves and our surrounding is kinda our forte. That's why we've spread so much on Earth.
Screw roots: we'll adapt and become root growers or new roots ourselves. Each time someone prophetized impossibility for human ideas, some amongst our kind devoted themselves to prove our scientific divine prophets WRONG. Maybe even just for the sake of it.
Tell people they won't survive long. They may search hard and find a way to survive almost eternally just to piss you off.

Oct 10, 2019
I have no doubt that humans, if they are willing to learn, work hard and progress as far and as fast as is humanly possible, can make it to the Stars and explore the Universe no matter how long it takes. To end it all on this one planet, or even in this one Solar System would be a waste of what was given to the human race over a million years ago.
It is for this reason that the Universe was created, and to borrow from "Star Trek" the famous words, "to boldly go where no man has gone before".

I guess the references to the religion were too much.

No body knows if this is true or not. We might have come from somewhere else. Netflix has a cool series "The expanse" which has humans living on mars, earth and asteroids. The humans living on asteroids in low g have developed in such way that they can't operate on earth normally. Weak and light bones etc. It might be that these changes would happen fast if a generation is actually born in low g.

sperm fertilizes the egg devices land on inhabitable planets by the thousands...then robots raise first generation babies......

Oct 10, 2019
Risking Otto's downvote against anything religious, I'll point to the Abrahamic myth of Cain and Abel with primary lesson of greed overshadowing the story.

Apply this narrative to humankind and one can see we're simply not ready for space if we continue to war each other, coveting each other's material possessions and committing murder. Our deeply rooted propensity to divide and conquer will always be our undoing, possibly even more so as we develop AI.

Singularity? More likely we'll spawn a Dualarity which will be very very very bad for us. A movie from 1995 titled "Screamers" visualizes this dilemma very well. Based on the work of Phillip K. Dick who also provided the source for various sci-fi works like Blade Runner, It's one of those 90's b-budget movies that are better than most a-budget movies today. A must see.

Oct 10, 2019
We're gonna go out and colonize the asteroids, if we live that long. It's inevitable.

Oct 10, 2019
Guys - he didn't say that humans will never go there. Just that we will not migrate there (i.e. transplant the entire population of Earth to another planet)

Guess what? Adaptation of both ourselves and our surrounding is kinda our forte. That's why we've spread so much on Earth

Adaptation only works if the environment changes slowly and is pretty benign to start with. If it changes too fast species go extinct (as has been shown many times in Earth's history on small and large scales).

Another planet would be radically different from Earth in almost any respect (atmosphere, gravity, soil chemistry, temperature range, pressure range, ...). It'd be like plunging humans into the ocean depths. You can do this for millions of years and any humans you throw down there will just die and never adapt.

No.

Instantaneous is FTL.
No, it is not.

Einstein was famously wrong about quantum mechanics. "Spooky action at a distance" not only occurs,

Einstein knew very well what he was talking about. He was talking about ACTION at a distance. He was specifically not talking about INFORMATION TRANSMISSION at a distance (he chose his words very carefully, there).
FTL would be INFORMATION TRANSMISSION at a distance (which is prohibited - even under quantum mechanics). It's the difference between quantum information and (classical) information. Quantum information can appear "superluminal" but it cannot be used to transmit a message (or move a thing). Only classical information can (and that is limited in a hard way to c).

Einstein-Rosen Bridge, i.e., a wormhole, which might be another (or related) FTL option.

Nothing moves FTL in an E-R bridge.

There is no pint in debating that the spaceship is already built, the planet is overpopulated, NASA is going to the Moon and that commercial spaceflights are already available. He should of thought of the trend first. We all like to explore ;)

Space travel is the modern Tower of Babel. Mankind will not leave the Earth. Men have left the Earth at unsustainable expense considering the demands of the welfare blackhole.

I dont downvote religionists. What's the point? They enjoy being martyrs. And I encourage them to come here and expose their nonsense where it can be debunked. Thanks for making the world just a little better.

??? Not about greed but JEALOUSY. Actually, it was an iteration of the perennial herder vs grower conflict. Abel gave his father meat from his herd while cain only had salad.

Once the birthrate is under control, conflict will subside. It's not about wants, it's about needs. But true, it is the greed of all religions that want to fill up the earth with themselves to the exclusion of everybody else, that is the primary cause.

There is no pint in debating that the spaceship is already built, the planet is overpopulated
No matter how many emigrate, if the birthrate remains the same in undeveloped, religion-dominated cultures, overcrowding will endure and along with it conflict, suffering, and abuse.

I keep thinking of poor thanos picking fruit in his garden. In only a few gens he would have gained the forbidden knowledge of malthusian overgrowth. He would have seen pops recover and conflict resume. And it would be that much worse because the religions have higher birthrates than everybody else. Only 20 years to double the pops of hasidim, wahabi, Kurdish, amish.

He should have taken half of all the species. Niches take much longer to fill. Sadly, the human race would probably have been at the top of the list, ending forever the perennial DC vs Marvel conflict.

Yeah I know, lanterns everywhere.

The way to fight overpopulation is by education. Education also helps science and space travel. Educate people and it's a win-win for everybody.

Yes, the mafias, takers, war profiteers being the proverbial boil on the back of the mercantile/sociable class since time immemorable. All the way back, since the first water holes and best fruiting trees were guarded by the first bully protohominid gangs. It makes one wonder will they somehow follow the mercantile/sociable into space as they try to perfect zero-g corn growth and crank out our first caskets of space made soft-drinks.

Curious how, on news of Professor Emeritus Michael Mayor having received the Nobel Prize for physics, phys.org displays a photo of him in a very unflattering pose, as if he were some kind of bar-room buffoon caught in the act of saying "I dunno, already!".

Nice one, PO...

Cotexx the troll says
The way to fight overpopulation is by education
-Fundys of all persuasions are very well educated to the fact that anything you have to teach them is evil. And they are smart enough to know that having as many babies as possible is the best way of turning their minority into a majority.

"There are three religious tenets that drive our growth: our women don't use birth control, they get married young and after they get married, they stay in Kiryas Joel and start a family. Our growth comes simply from the fact that our families have a lot of babies, and we need to build homes to respond to the needs of our community." — Gedalye Szegedin, village administrator, kiryas joel

"The name "Boko Haram" is usually translated as "Western education is forbidden"... Western influence is a sin" and "Westernization is sacrilege"

-But please do go and try to teach them something new, and learn for yourself the meaning of the term 'blasphemy'.

It is very easy to travel fast than light WITHOUT breaking the light barrier.

Until 'scientists' work that little puzzle out, humans are going nowhere..

Well...if it's so "easy" then I'm sure you can tell us all how it's done.

Or is it a big secret?

It is astounding to read these foolish dreamers talk about how "we" will travel to distant stars and then cite the need for technologies that neither exist or are never going to be financially feasible. A single mile of freeway costs 5-7 million dollars using low skilled workers dressed in off the shelf gear and clothes. There. Will. Be. No. Interstellar. Anything. Never. Not in your lifetime. Not in a hundred lifetimes. But the real tragedy is that this kind of hyper-dream of a new earth, erodes the will to make this, our only cost-effective livable planet, a paradise for eons to come. It is sheer madness to say, "hey guys, we said we'd never (insert your scientific achievement here) and then we did it". The distance and cost to go to a place a nearby as Mars is inescapably high. We are on our spaceship now. Put everything we have into making it last. We owe that to future generations.

To address the environmental concerns here on Earth, we need easily accessible mineral resources that are currently under the control of individual countries and are used for various sorts of coercion. Our only hope of making a post-scarcity economy in which humans will not breed beyond the carrying capacity of our planet is to find and harvest these resources.

Those resources are not here on Earth. They're floating around between Mars and Jupiter, and in mining them we will learn what we need to know to build and crew ships that will go beyond our solar system.

Oct 10, 2019
So mining the asteroids and finding out how to spread beyond the Solar System is bad and deserves a downvote?

Still looks like Russian trolls.

And I'll keep pointing that out as long as you keep downvoting without posting any arguments.

There will be no interstellar travel without life extension or enhanced intelligence. Nor will there be interstellar travel without a singularity type event, where AIs will be able to help us design and build travel environments that are bio-engineered, approaching light speed, and pleasantly liveable. These are feats that require super-human lifespan and endurance, as well as superhuman intelligence. Once we get to a credible three hundred year lifespan, and can travel on relatively fast interstellar crafts that are indistinguishable from a small planet, travel to the nearest exoplanets will become feasible. So we will travel to worlds outside the solar system, but long past the point that we are anything we would currently consider human.

Limit propulsion to using only electromagnetic forces and you'll be forever limited by the speed of light.

Well, it's as "easy" as entangling our moon with that, of another habitable planet and then surfing through the generated wormhole. After all, that's exactly what the aliens, who surreptitiously manipulates us, did when they created our moon.
But, shhh... they don't want those human "scientists" in on that little puzzle.

Oct 10, 2019
Hew-mons and their wounded pride! I collected a lot of downvotes upthread for telling you straight up your species will never master interstellar travel. Most of you respond with gibberish about faster than light travel. On my home planet our young learn about relativity (and causality!) in kindergarten! But carry on as before … you are proving my point!

rrwillsj: "if you resent this scientist's concept of pitiless reality . . . what are you doing,
what physical effort are you making? to change that reality?"

I am going to disagree with you on this one. The old guy expressed his learned opinion about the future (no breakthroughs) and we are expressing ours, such as they are. It is another thing entirely to ask someone to develop workable FTL simply because our guesswork disagrees with his guesswork. BTW, since you asked, I could suggest a directed research program that would shed at least a little light on the subject, but I suspect it would only differ slightly (or maybe not at all) from what scientists are already looking into. Lots of people are depressingly obtuse, antialias_physorg for example, but there tends to be enough brilliant people around to keep the ball rolling, even without my help. :-)

The 77-year-old said he felt the need to "kill all the statements that say 'OK, we will go to a liveable planet if one day life is not possible on earth'."


This is a well-intentioned, but fundamentally flawed approach. Only a troll/moron would assert it is ok to destroy Earth because we can always go to another planet. The reality is even attempting travel to another habitable exoworld or terraform a dead one will teach us how monumental the challenge really is. When I think about what it would take to even partially terraform Mars, I gain a more profound appreciation for Earth. Earth is precious beyond compare, and that is not going to change anytime soon.

Why is everyone forgetting about the Orion Project. That system is capable of projecting city size spacecraft at relativistic speed toward other stars..

Every new gen born ignorant. Every new gen needs to be educated all over again. Leftists thrive on this unfortunate reality.

'Sucker born every minute.'

Old tricks work great on new dogs.

The best way to educate is to take a little time and post excerpts.

"Nuclear Pulse Propulsion - The added weight of the reactor reduced performance somewhat, but even using LiD fuel it would be able to reach Alpha Centauri, the closest solar system to our own, in 100 years (approx. velocity of 13,411 km/s, at a distance of 4.5 light years - equivalent to 4.5% of light speed)."

-Idiots like smartist will still try to argue with you as if they're your opinions rather than facts from experts. But they will still look like idiots for trying.

what it would take to even partially terraform Mars
That's why mars wont be terraformed. By the time it's possible, the martians who have been living there for several gens in complete comfort and security in their vast underground cities, wont allow it. They wont allow the extensive industrial, energy, and transportation infrastructure they built on the clean, sterile, calm, and dry surface to be mucked up and overgrown by rust, mold, mud, and weeds.

They wont tolerate the centuries of pressure variation, floods, lightning storms, tornados and so forth, not to mention the bugs, fungus, root systems etc that would force them to completely replace surface installations with vastly more expensive and less durable replacements.

Machines love mars just the way it is. Rovers designed to last 6 months have lasted for years and years. Subsurface martians will covet the isolation that used to exist here on earth, before we began transporting invasive species and disease everywhere.

"Migrate" has different meanings to different people. If by migrate you mean people will one day climb aboard a space ship and travel to another planet like in Star Trek, that is indeed a possible never. If by migrate you mean spread the species, that will happen and be much easier than thought. Consider this idea for example: we will soon be able to 3D print a viable egg and sperm. So to spread our species we only need to send a 3D printer across the cosmos. Once it finds somewhere interesting, the printer can use local resources to make some robots that will do the basics of creating a safe habitat, and then we print a bunch of sperm and eggs, and raise test-tube kids. Presto, mankind across the universe. There is no need to send an actual person. Though still a monumental exercise, sending a 3D printer to "boot-strap" a new civilization, is orders of magnitude simpler in design than trying to send actual people. But for us actual people, we just got one Earth.

Oct 10, 2019
Yeah, unless we use relativistic time dilation to our advantage, it's unlike anyone living on Earth will ever visit a distant solar system. And if they do that, they're not going to come back to find anyone they ever knew alive.

Star Trek ain't ever gonna happen, given the physics we know now.

Oct 10, 2019
In the late 1800's, other supposedly wise learned scientists proposed with equal intensity that man would never never no never fly.

So what? Who wouldnt want to travel to the future? There will be plenty of people there too (maybe)

Robust answer, essentially Fermi's trivial answer to his own Question - "where are they" - since we don't know if star flight is possible.

Oct 11, 2019
Star Trek ain't ever gonna happen, given the physics we know now.


Highly misleading and completely unproductive, even if it is technically correct. Here are a few more:

"Building particle colliders is a complete waste of time, given the physics we know now."
"The universe is doomed and we should just give up and die, given the physics we know now."
"Man will never fly (pre-1903), given the physics we know now."

All of these statements fail to acknowledge there are GIGANTIC HOLES in our knowledge. 72% of the universe is dark energy, which works the opposite of gravity and pushes matter apart, so you might as well call it "anti-gravity," but we do not understand it. 23% is invisible dark matter, of which we are ignorant, despite heroic efforts to understand it. So right there, we are clueless about 95% of the universe.

"Humans will not 'migrate' to other planets, Nobel winner says"

-You know I've seen this story in many different places. Limbaugh referred to it today. He obviously only read the clickbait headline and concluded it was about mars when in fact it's about other solar systems.

Fake news is an epidemic. The only solution? AI.

if they can invent a ship that can go half the speed of light and plus use of cryogenics, that could reach the nearest star in about ten years or find some fuel source on mercury or Venus like unobtainium or naquadah that is not on earth that could be used for much faster ships.
