Deep-sea sediments reveal solar system chaos: An advance in dating geologic archives

Deep-sea sediments reveal solar system chaos: An advance in dating geologic archives

A day is the time for Earth to make one complete rotation on its axis, a year is the time for Earth to make one revolution around the Sun—reminders that basic units of time and periods on Earth are intimately linked to our planet's motion in space relative to the Sun. In fact, we mostly live our lives to the rhythm of these astronomical cycles.

The same goes for climate cycles. The cycles in daily and annual sunlight cause the familiar diel swings in temperature and the seasons. On geologic time scales (thousands to millions of years), variations in Earth's orbit are the pacemaker of the ice ages (so-called Milankovitch cycles). Changes in orbital parameters include eccentricity (the deviation from a perfect circular orbit), which can be identified in geological archives, just like a fingerprint.

The dating of geologic archives has been revolutionized by the development of a so-called astronomical time scale, a "calendar" of the past providing ages of geologic periods based on astronomy. For example, cycles in mineralogy or chemistry of geologic archives can be matched to cycles of an astronomical solution (calculated astronomical parameters in the past from computing the planetary orbits backward in time). The astronomical solution has a built-in clock and so provides an accurate chronology for the geologic record.

However, geologists and astronomers have struggled to extend the astronomical time scale further back than about fifty million years due to a major roadblock: solar system chaos, which makes the system unpredictable beyond a certain point.

In a new study published in the journal Science, Richard Zeebe from the University of Hawai'i at Manoa and Lucas Lourens from Utrecht University now offer a way to overcome the roadblock. The team used geologic records from deep-sea drill cores to constrain the astronomical solution and, in turn, used the astronomical solution to extend the astronomical time scale by about 8 million years. Further application of their new method promises to reach further back in time still, one step and geologic record at a time.

On the one hand, Zeebe and Lourens analyzed sediment data from drill cores in the South Atlantic Ocean across the late Paleocene and early Eocene, ca. 58-53 million years ago (Ma). The sediment cycles displayed a remarkable expression of one particular Milankovitch parameter, Earth's orbital eccentricity. On the other hand, Zeebe and Lourens computed a new astronomical solution (dubbed ZB18a), which showed exceptional agreement with the data from the South Atlantic drill core.

Interacting resonances are also suspected to cause chaos in the Solar System, although significantly more complex than the simple system depicted here. Credit: Richard Zeebe

"This was truly stunning," Zeebe said. "We had this one curve based on data from over 50-million-year-old sediment drilled from the ocean floor and then the other curve entirely based on physics and numerical integration of the solar system. So the two curves were derived entirely independently, yet they looked almost like identical twins."

Zeebe and Lourens are not the first to discover such agreement—the breakthrough is that their time window is older than 50 Ma, where astronomical solutions disagree. They tested 18 different published solutions but ZB18a gives the best match with the data.

The implications of their work reach much further. Using their new chronology, they provide a new age for the Paleocene-Eocene boundary (56.01 Ma) with a small margin of error (0.1%). They also show that the onset of a large ancient climate event, the Paleocene-Eocene Thermal Maximum (PETM), occurred near an eccentricity maximum, which suggests an orbital trigger for the event. The PETM is considered the best paleo-analog for the present and future anthropogenic carbon release, yet the PETM's trigger has been widely debated. The orbital configurations then and now are very different though, suggesting that impacts from orbital parameters in the future will likely be smaller than 56 million years ago.

Zeebe cautioned, however, "None of this will directly mitigate future warming, so there is no reason to downplay anthropogenic carbon emissions and ."

Regarding implications for astronomy, the new study shows unmistakable fingerprints of solar system chaos around 50 Ma. The team found a change in frequencies related to Earth's and Mars' orbits, affecting their amplitude modulation (often called a "beat" in music).

"You can hear amplitude modulation when tuning a guitar. When two notes are nearly the same, you essentially hear one frequency, but the amplitude varies slowly—that's a beat," Zeebe explained. In non-chaotic systems, the frequencies and beats are constant over time, but they can change and switch in chaotic systems (called resonance transition). Zeebe added, "The change in beats is a clear expression of chaos, which makes the system fascinating but also more complex. Ironically, the change in beats is also precisely what helps us to identify the solution and extend the astronomical time scale".

Everything that these scientists are finding are relative to the Clockwork of the Universe. In each level of that Clockwork, even down to the smallest subatomic particles, there is that clockwork that determines Motion and Momentum, velocity, duration of an Event/Action, distance, temperature, kinetic energy, and the Rotation of a planet or Star that can be measured by hours, minutes, seconds, and smaller sub seconds. Each planet, Star, galaxy has its own Clockwork that is obeyed which, in turn, keeps all that is within the Clockworks's control running smoothly with very few glitches.
Even during galactic mergers, the Clockwork of each body arranges each body to configure that the spaces between each is maintained. When a glitch happens, such as a collision between 2 bodies it is most often the result of the gravitational pull of one body/Mass exceeding the resistance of the other Mass.

As I have often said here in Physorg, there is no such thing as 'time'. This is but a Concept that is produced by the human mind and has no spatial substance at all, but is only a convenient noun to describe the Passage/Durations of Events and Actions that are measurable by Clocks. On Earth, it is the sunrise to sunrise 24 hour rotation cycle of the Earth that is measured by clocks. On another planet, its rotation cycle would be comprised of a different set of hours, minutes and seconds.

i have to say, as a new person perusing this site -- and then out of curiosity, both yours and Egg's post histories -- you sound incredibly angry and disturbed. you wear your hate on your sleeve and it's not a good look.

i would be embarrassed for myself to post the things you post, and then read them later knowing i posted them.

how does it make you feel to know that some of the most (arguably, *THE* MOST) influential men in science were basically... practicing mystics? were involved in esotericism of all sorts? that the people who had advanced humanity forward in science/tech envisioned the world and universe in a way that you absolutely DESPISE?

Aug 29, 2019
or howsabout -- does it make you angry every time you have to write the year # on forms/taxes/checks/anything?

do you think that the secularizing of "AD" to "CE" *actually changes* what the modern world's calendar system is based on? it makes me chuckle a little bit inside to imagine someone actually getting twisted into knots about that, yet with the hateful manner in which you write, i can totally see you having that type of reaction! am i that far off, or is there some shred of truth to what i'm saying?

I seem to recall that as the solar system revolves around the galactic center, we're not quite on the galactic plane. So twice during each revolution the solar system passes through the galactic plane, which has more leftover dust/gas/debris than above or below the plane. It's probably been thirty or forty years now since I read about this - I don't have a clue now of the number of years for one revolution. Can someone help out.....

i am honestly wondering that about you. whose hand is up YOUR rear? your reply was only marginally coherent so there's no use quoting the whole screed.

here's a great test -- you give me YOUR list of the most important and/or influential scientists/physicists/mathematicians/intellectuals/WHOMEVER you think has benefited humanity *the most* by their study and work, and i will be HAPPY to give you mine. :)

Aug 29, 2019
I'm going with Galileo, Newton, Einstein, Dirac, Maxwell, Zwicky, and Feynman, for starters. I'll have plenty more if needed.

Let's see yours.

Aug 29, 2019
For example I could also name Lagrange, Hippocrates, Laplace, Democritus, Pythagoras, and Lavoisier. The list goes on. Pasteur for example.

Waiting over here.

I've heard that at one point there was an ice age that caused the oceans to freeze down to 1 mile in depth, and the average temperature was -50 degrees at the equator. I was thinking variations in the Sun's energy output could cause this. Now, I'm thinking orbital variations could be more likely. However also consider what would happen if the Solar system were to pass through a nebula. Would the gas in the nebua cut down the solar energy enough to cause that kind of freezing? Hmmm.... More research needed.

The sun goes up and down every 26,000 years, a vibration compared to the 220,000,000 years for the solar system to orbit the galaxy. A second up and down motion due to the warped galactic disc has a period of 63,000,000 years.
No proven correlations tied to the up and down time periods.

This is progress, soon after this type of astronomical/geological clock record was presented. Usually when this happens the method is useful and robust. Mostly the use will be to straighten out the geological (and biological) record datings.

I seem to recall that as the solar system revolves around the galactic center, we're not quite on the galactic plane. So twice during each revolution the solar system passes through the galactic plane, which has more leftover dust/gas/debris than above or below the plane.

Indeed, neither climate nor extinctions have been found to have correlations. (Best tested with autocorrelation methods.)

So the PETM connection is an extraordinary claim, but the evidence seems to be ad hoc pattern recognition (i.e. pure coincidence). We'll have to wait and see how that hypothesis fare.

Some of the dialog seems erased - or possibly the commenter is on my blocking list, your references are unclear - if that makes you feel better. Certainly rudeness is to be pointed out.

However, you are rude too. How dare you suggest, as per the usual superstitious pablum, that early scientists living in a dominantly superstitious society were using science to "forward" anything!? As your own terminology suggest they were scientists in other areas and *that* forwarded society. Superstition held them back.

And, contrary to the pablum, that an individual can be both scientist and superstitious does not mean science and superstition is not contradictory.

I tried dating Geologic Archives but she was mired in too much chaos.

Aug 30, 2019
Let me say that again: superstition is delusion. Science, that moves society forward, has in the first two decades of this century done the same number on all religion as it did the century before on astrology.

Horoscopes do not work (psychology science blind tests in the 80s), intercessory prayers do not work (religious science blind tests in the 00s) & 'souls'/'afterlife'/'free will' does not work (LHC results 2012-17; netting a Noble Prize for the Higgs discovery that means we know we are just biochemical machines obeying physics laws).

Hypothetical mechanisms star 'signs' are human projected (astronomy mapping star distances in the 30s) and religious 'gods' are human projected (cosmology mapping the universes as 100 % mechanical 2018 by way of Planck and finding the border constraint of flat space).

Are you done being rude, suggesting humanity is "advancing humanity forward" by remnants of Bronze Age (self)delusions such as religion? I hope so.

Aug 30, 2019
LOL Torbjorn is one of those who are deathly afraid of superstition; so much that he will go into all sorts of contortions to avoid walking under a ladder or allowing a black cat to cross his path, all the while thinking that there is no such thing as superstition while railing against it. He pretends to have a strong dislike of superstition only because he is commenting on this science site.
Torbjorn (and many others) are locked into their own beliefs that the material is all that there is, and the dreaded UNPHYSICAL entities that reside in the Universe are to be scoffed at and disbelieved. But the very idea of religion cannot be avoided for humans such as Torbjorn. They think about religion ALL THE TIME. It is in their dreams - haunting them.

Aug 30, 2019
@granville
I am certain that science will come around to my way of thinking regarding the nonexistence of 'time' as a thing of Matter/Energy that they pretend it is.
There have been others in the past who tried to explain that absence and nonexistence. Perhaps they were not telling it in the correct media, or didn't go into as much detail as I have done.

Aug 30, 2019
@granville

I was totally amazed when I read this in the article:
"The astronomical solution has a built-in clock and so provides an accurate chronology for the geologic record."

It appears that science may be starting to come around to my way of thinking. That each and every planet is its own CLOCK, where its rotation of X hours, X minutes and X seconds is relative to its sunrise to sunrise cycle. I'm sure that someday they will also see that all galaxies have their own clockwork, as well as all Stars and planets have theirs, and the whole Universe itself is a Clockwork of a NATURAL ORDER. Just like the ticking of an Atomic Clock.
I have no problem with their referring to the flow of Events and Actions and their measurable Durations as 'time'. The term is too ingrained in the brains of humans.

no wonder these trolls are unwanted & banned from the yech! mumbo-jumbo sites

they have managed to embareass the other superdolts
that's why these apologists for error haunt the science sites, hoping we will feel sorry for them

what has superstition accomplished on behalf of Humanity?
not a damn thing!

recently, researchers announced the first technology based on the science of the Theory of Dark Matter
cutting edge machinery for geological prospecting

from all the fairytale religions & fakir cults & pseudo-sciences of the woomomgers?
A RESOUNDING SILENCE!

their most "advanced" tech to date?
ouiija boards & orgone boxes
chirp, chirp, chirp...

so you suggest i treat these mentally & morally deficient trolls
with pity for their many failures in life?

screw that! i an going to revel in rubbing their noses in their own shit

yes, that is my character flaw to despise these vermin

@granville

I and my Team are not allowed smugness and self-satisfaction. Those two emotions are native to humans and human values according to what they had been taught to regard as important as children and young adults. Humans become proud of their accomplishments, but it is not long-lasting. Something else will take its place.
In other words, granville, it is Pride that is the downfall of all humans and Angels. So we don't indulge ourselves in such emotions of the Mind.
