Looking for a definition of dark matter and energy!?

Question

Theory, according to my reading, seems to indicate that the reason gravity is such a weak force is, because it is leaking out of our universe, into parallel universes. This begs the question, whether what we call dark matter (and are unable to detect other than through its impact gravity wise), is simple gravity leakage from parallel universes?

Answer 1

I have a tough time with the whole concept of dark matter. Okay so the universe is expanding at a rate slower than what all the matter that we can see predicts. So they come up with this dark matter.

It is like doing an experiment and your calculations do not match the results, so you say, "it must be because of another form of matter." You would be a laughing stock. I think it is rather naive of astronomers to think they can see all the matter in the universe. Not all of it is going to emit light. Could there not be very thin clouds of matter stretched over vast distances that we do not even know about?

Answer 2

That theory makes the assumption of multiple universes (see Quantum Mechanics Many Worlds Interpretation). I'm of the opinion that Dark Matter is in the form of Gravitational Solitons. A soliton is a nonlinear wave. Einsteins General Theory of Relativity predicts the existence of Gravitational Waves being created by supernovas, binary stars, etc.

Although Gravitational Waves have yet to be detected in an explicit manner.

Gravitational Waves carry a static Gravitational Field with them. Since Solitons do NOT disperse, or rather the energy of a soliton disperses very slowly, it makes sense that Gravitational Solitons could have been created during the big bang and that they clump together, warping spacetime causing attractors, and gravitational lenses.

Answer 3

All the theoretical work about dark matter and dark energy was done before the discovery of NUETRINO OSCILLATIONS. This discovery is going to change everything.

Dark matter and energy may still exist, but all the math and theory work connected to them will certainly change soon

search on "violations of quantum mechanics in gravity theory"

and Micheal Murphy at Cambridge saying that physical constants have varied since the beginning of the universe, i.e. the speed of light has not always been the same. he says LIGHT TRAVELLED FASTER IN THE PAST.

I'm not sure about that, but i am sure he's right, the physical constants of our universe have changed over time

Answer 4

Dark matter and dark energy Both are mathematical concept like ether was used for the light wave to propagate. Whenever these mathematicians miss something they add some hypothetical thing to their equation. Some stay and some thrown out later. But in reality there is no gravity leak or dark matter or energy

Answer 5

I think that dark matter/energy is just another realm of physics we haven't even begun to understand yet. They might be the solution to a lot of things in this universe, ranging from gravitational force to parallel universes to time travel.

You could look up dark matter and/or dark energy on wikipedia.org for more information on the subject.

Answer 6

In cosmology, darkish ability is a hypothetical style of ability which permeates all of area and has reliable detrimental rigidity. in accordance to the perception of relativity, the outcome of this style of detrimental rigidity is qualitatively such as a rigidity appearing in competition to gravity at great scales. Invoking such an result's at the moment the most regularly happening approach for explaining the observations of an accelerating universe as well as accounting for an significant area of the lacking mass interior the universe.

Answer 7

Yes I've read about this in Stephen Hawking's "The Universe in a Nutshell". It's a good book.

Answer 8

it influences the evolution of the universe gravitationally

Answer 9

Maybe. No one has actually "seen" dark mater to find out (hince its name!).
