Dark Matter?

Question

10 points to the person who can best explain what dark matter is to me.

Answer 1

Astronomers believe that dakr matter is a "cosmic glue" holding together rapidly spinning galaxies and controlling the rate at which the universe expands. Dark matter is thought to make up 90% of the universe. It can be detected by observing its gravitational effect on objects.

Examples of object that may be dark matter include black dwarfs (dead white dwarfs). Brown drawfs are also considered dark matter. Dark matter could also be large dwarf galaxies which # in the billions and subatomic particles.

Answer 2

There is no dark matter. The observation that is attributed to dark matter is due to the dimensional geometry of the universe.

The universe started with the Big Bang and all that exist in the universe is moving outward from that point. Observation of redshift indicates that this outward transition is not a spatial dimension. This observation is the redshift of all objects away from any observer anywhere in the universe.

The result of this geometry is that all objects in the universe are on this curve produced by the expansion. This is the same as putting a marble in a bowl. The marble in the bowl is able to spin around a center object, without flying outward, much faster then on a flat plate. On a flat plate the only force that would allow the marble to circle the center is the gravitational attraction to the center object. As you can see even a very small curve to the dish will allow a faster circular motion.

Remember if you have a mystery look for the common sense answers first.

Answer 3

Because I feel like it, I'm going to recant a bit.

Dark matter is basically like ordinary matter but it's though to make up most of the universe, we can't see it and the only way we know it's there is because like ordinary matter, it has gravity.

Because we can't actually see dark matter, there is debate over the true nature of it. Some feel this matter is simply ordinary matter that isn't emitting or reflecting light. Some feel this matter is an exotic form of matter that doesn't interact with ordinary other than through gravity....that is, it's invisible and you wouldn't be able to hit it with a baseball bat but if it occupied the same space as you you'd be heavier.

Answer 4

Dark matter is a theoretical matter that no one can see. It is believed to exist to explain the gravitational forces that would be need to keep galaxies from flying apart. It may be 89 to 90 % of the matter in the universe.

Answer 5

Well, I hope I don't offend anyone but. I believe personally that dark matter either is God, or is in some way connected! Thats my personal theory. I respect astronomers and people who study the universe, but I don't think every question will ever be answered. And I see it as impossible that the universe just created itself by chance. Someone had to create it!

Answer 6

Hi. Right now science can not explain what dark matter is. It could be a manifestation of string theory and perhaps the interaction with p-brains, but your guess is as good as mine. Some possibilities? Gravitational effects from virtual particles, vacuum energy, huge numbers ot tiny black holes, planet sized bodies in unanticipated numbers in interstellar space, to name a few.

Answer 7

When astronomers calculate the spin rate of some visible galaxies and thier visible mass (e.g., by counting stars) the spin rate is not right for the visible stable galactic spin. More mass is needed which they assume they can't see (remember that they counted visual objects to get the mass) thus they call it dark matter.

It could very well be that the gravitational equation is different at greater distances.

Hope this helps

Answer 8

Sorry but there is no answer yet. An explanation or, better an identification, of dark matter will be worth the Nobel prize.

Answer 9

Its the space or place where there is nothing.Like no black holes,asteroids planets,etc.If u look thru a satellite u could c something like dots of dark glowing blue colur.I saw a video I got this info from tht.If u wanna contact me.
