Research looks at how light and matter behave around black holes, other celestial objects

Jul 22, 2009

Dr. Dentcho Genov, an assistant professor of physics and electrical engineering at Louisiana Tech University and a Louisiana Optical Network Initiative (LONI) Institute fellow, is featured in the most recent issue of Nature Physics, one of the most respected and prestigious physics journals in the world.

An article titled, "Mimicking celestial mechanics in metamaterials," links the newly emerging field of artificial optic materials with celestial mechanics in order to investigate celestial phenomenon in a controlled laboratory environment. Metamaterials are artificial structures that display properties beyond those available in naturally-occurring materials.

" is the leading physics magazine in the world and only features research that, according to their criteria, is of 'extreme importance to scientists in a specific field' and that has broad interest," says Genov. "We are happy that our work and its importance to the scientific community have been recognized by such a highly prestigious journal."

Genov along with researchers from the National Science Foundation (NSF) Nanoscale Science and Engineering Center at the University of California and the Lawrence Berkeley National Laboratory in Berkeley collaborated on this article.

Using elements of Einstein's , this research allows scientists to observe more closely how light and matter behave around massive celestial objects such as "black holes."

The effect on light due to curved space-times generated by complex gravitational fields can now be reproduced with precisely engineered artificial optical materials, referred to in the literature as "metamaterials."

"It may be possible, in the very near future for scientists to closely study the interaction of light with strange objects such as 'black holes' or to borrow from the stability of planetary motion to create new types of near-perfect optical traps that can effectively 'store' light," says Genov.

This research is also closely related to technology Genov and others helped develop for the "invisibility cloak", which involves metamaterials that can conceal objects from almost anything that travels as a wave, including light, sound and, at the subatomic level, matter itself.

The "invisibility cloak" was ranked #7 in both Time and Discover magazines' lists of the Top 100 Science Stories of 2008.

"This recognition confirms that the engineering and science faculty at Louisiana Tech are contributing significantly to relevant and vital science discoveries," says Dr. Stan Napper, dean of Louisiana Tech's College of Engineering and Science.

"Our students are directly benefiting from these outstanding researchers who are also outstanding educators."

How do the orbs interact with each other?

They open up energywaves, by which they interact with each other.

The less the orb has exterior surface, the less it interacts with other pieces. Also the density of energy matters as well.

In a energy concentration there can be a lot of energy, although it would have just a little exterior surface in relation to other orbs.

The denser the energy in an orb is, the less it has exterior surface in relation to the quantity of energy.

The less exterior surface, the slower the energy opens up away from the orb and the less it interacts with other orbs.

The denser the energy of a piece is, the more efficient it stops to itself for example the neutrinos coming from the stars and also the less there comes neutrinos away from the piece.

There woun´t come any neutrinos of the stars from the direction of a black hole, because they stop themselves to a black hole.

However, towards the black hole there move neutrinos all the time and they expand and open up energywaves, while transfering their kinetic energy with them to the orbs.

From the pieces that move near the black hole loose more neutrinos from the side that it away from the black hole. This is how a certain exterior pressure is formed around the black hole.

The closer to the black hole the piece is, the less energybundles come from backside of the black holes and the stronger the exterior pressure is.

When one understands that all the energy concentrations expand and open up energywaves that have the nature of expanding energyconcentration, one can undestand that the black hole does not draw other pieces towards itself. It devours all the other pieces, because it expands and pushes pieces that locate nearby away from itself slower than the pieces and the black hole itsel do expand.

However, some of the black holes are in a way in a diet. They push the gas that locates nearby away from themselves faster than they expand.

Someone may wonder, why the black hole finally begins to reject the pieces that approach the black hole faster than the black hole and the piece themselves expand. It is based on a fact, that allthough the black hole opens up slowly its energy, do these dense energywaves have large energic particles, which also transfer their kinetic energy with energywaves opening up from themselves towards the expanding atomcores of other orbs.

The modern physics does not understand these large energic particles. According to my theory, the speed of these large energic particles has accelerated just because of the fact, that they also do expand and open up energywaves by which they can make the large energic particles in front of them to speed up all the time.Their speed accelerates slower than the speed of the photons. Correspondingly their speed slows down slower than the photons speed when they move for example towards the sun. The speed of a ship accelerates slower than the speed of a boat. The speed of the ship also slows down slower than the speed of a boat.

This way it is easy to understand how the expanding star that pushes itself away from the expanding black hole explodes a lot of its energy towards the black hole. Those opening and expanding energybudles that come from the expanding black hole make the expanding atoms of a star explode faster than normally. It achieves an illusion that the black hole absorbs with some kind of gravitation from a star the mass of a star towards itself.

In fact, the energy coming from the black hole makes the expanding star to explode its energy much stronger than normally. With this energy that explodes towards the black hole it pushes itself away from the expanding black hole in a curved orbit.

"How do the orbs interact with each other?"

Which orbs and which interactions?

The idea behind using metamaterials is AFAIU it that negative refraction can model some gravitational physics. For example the gradients of gravitational lenses according to an astronomer (I think) on the UT blog.

The way negative refraction works isn't exactly clear to me, as even though it likely will be study basics in the future I haven't delved into todays research. FWIW, my phenomenological take (and I welcome any experts here):

Negative refraction is like negative (differential) resistance, you can get it out of Maxwell's equations modeling (passive and active) material systems by complex permittivity and susceptibility.

More precisely metamaterials use LC equivalents to affect light. The effect is curious, the phase velocity of the waves are antiparallel with the energy Poynting vector flow. (But the group velocity is parallel, thus saving causality and energy.) Presumably this is what permits the extinction of the light within the materials and the guidance around them.

In short, metamaterials seems to me to act like phase array antennas to guide EM energy where you normally don't expect it.

And I'm sorry JukriS, but nothing you describe on black holes has any resemblance or even relevance to their rather well known physics. Wikipedia has starters for black hole physics if you are really interested.

Dark Matter is Cloaked Matter?
Dark Energy is Stored Energy within Cloaked Matter?

Black Holes in Deep Space can produce Negative Refraction, (or minimalise their observed space/time distortion)?

Neat solution. Provable?

I explained metamaterial character of vacuum a few years before. This behavior follows from foam character of vacuum, which is filled/formed by density fluctuations of Aether

The negative refraction of black holes is testable, if we admit, observable Universe is formed by interior of such black hole. After then we can observe reflection of remote stars from inner walls of such black hole. The cosmic hall of mirrors is based on such hypothesis.

In my opionion, we observed these reflections already.
