What do you think "dark matter" is?

Question

In outer space?

Answer 1

The idea of dark matter was intoduced to account for the way galaxies rotate. Since then there have been many obervations, such as gravitational lensing which can also be explained if dark matter really exists. Theories about what dark matter is fall into two main camps - it's either normal matter that we can't see because it's not being lit up, or it's exotic particles that don't make up normal matter. Right now there aren't many scientists who seriously doubt the existence of dark matter, and exotic particles seem to be the most likely candidates.

Answer 2

Pretty hard to see!!!

Just kidding. I don't really buy into Dark Matter.

Back in Newton's day, they had this problem with motion. See, they couldn't find anything that was standing still, so they couldn't figure out how fast anything was going.

See, if I walk past you, I'm going like 1 mile per hour.. but we're both on Earth, which is moving, and Earth is in the solar system, which is moving in the Galaxy which is moving.

There's no way to factor it all in, because there's no Zero point where nothing is moving. So, to fix this problem, they invented something called 'Æther'. Æther is present in all parts of the universe and doesn't move. It is supposed to be the grid by which all motion is judged by, it's completely undetectable by any means.

Sound like B/S? Well, it was. But they couldn't think of anything better for several decades, so they just went with it until Einstien came along with 'Relativity'. There IS no 0 motion. Motion is only relative to something else.

Dark Matter strikes me as similar to this. There isn't enough matter in the universe to account for the motion of the galaxys.. so there must be some kind of undetectable matter that compensates for this.

That's just how I feel about it.

Answer 3

To be honest, the terms "dark matter" and "dark energy" exist soley to express our ignorance of these phenomena. We have enough information to know they are there, but we cannot explain them - to the extreme that we have to make up these terms to describe them.

Answer 4

It really could be a number of things, blackholes, space dust. The link is good

Answer 5

Paris Hilton's brain.

Answer 6

Another mans theory which is only a theory and really holds no universal truth or value...

Answer 7

well, according to what I'm currently studying, it may be in the form of low mass dead stars that were never able to undergo nuclear fusion

Answer 8

stuff thats not lit up too good.

Answer 9

it is Black Hole
