Will the 'DARK MATTER' be able to stop the expansion of the universe ???

Answer 1

Actually astronomers and physicists are really quite puzzled by the whole universe. They have absolutely no idea what the dark matter is. Some postulate that it is neutrinos, even though they have not be able to show that neutrinos have mass. And they do not know if the expansion will stop or not. At the moment it appears that it will not but they are not certain. They do not know even why the matter of the universe has congealed into galaxies instead of a uniform soup. They have concocted elaborate hypotheses as to why, but they are still puzzled.

And best of all is why is there no anti-matter except in labratories?
Why did it not cancel out all the matter to begin with?

Answer 2

no. the universe will keep expanding. dark matter is a theory that is used to explain why everything in the universe stays in the same general area, relative to the expansion. the universe itself is expanding, but the dark matter theory helps to explain why everything isn't flying all over the place. people used to call it "ether", but that was changed to the dark matter theory. remember, it's just a theory.

also, relative to the distance traveled by the expansion of the universe, it's actually speeding up. things are flying away from us faster and faster. dark matter will not, and pretty much cannot stop the expansion of the universe.

Answer 3

Doesn't look that way, since there is also "dark energy" that is causing the expansion of the universe to speed up.
All of the matter (dark and visible) in the universe, through gravitational attraction, should have already halted the expansion and started pulling things back into a "big crunch" long ago if it weren't for the energy driving the expansion.

Answer 4

My guess is that Dark Matter is just a convenient filler for an unknown. Eventually, we'll discover more dimensions or some rational excuse for the behavior of the universe and Dark Matter will go the way of 'the world is flat'.

Answer 5

Due in part to the majority of the universe consisting of dark matter, I seriously doubt it. Even with the theory that it's molecular polarity will cancel that of "light matter" matter simply expands when not directly reduced by some physical or gravitational purpose. But thats just one mans opinion.

Answer 6

No. The Dark Matter can't stop the expansion of what is expanding, but can prevent further matter to expand.

Answer 7

In cosmology, dark matter refers to matter particles, of unknown composition, that do not emit or reflect enough electromagnetic radiation to be detected directly, but whose presence may be inferred from gravitational effects on visible matter such as stars and galaxies. Dark matter explains several anomalous astronomical observations, such as anomalies in the rotational speed of galaxies (the galaxy rotation problem). Estimates of the amount of matter present in galaxies, based on gravitational effects, consistently suggest that there is far more matter than is directly observable. The existence of dark matter also resolves a number of seeming inconsistencies in the Big Bang theory, and is crucial for structure formation.

My favorite type of dark matter is chocolate cream pie. Mmm...

Not as long as Darth Vader still eats bean burritos.
