Is the ammount of 'Dark Matter' growing, or not ?

Question

D'oh
watch out .. i'm asking about the 'theoretical mass' scientists added to explain galaxy-rotation and NOT - repeat NOT - the normal cold matter we cannot see.
So what's the prediction of this ?
ammount growing, shrinking, stable or yet not examined ?

Answer 1

Unknown at this time.

You really need to understand that these are not two distinct phenomena. The most common theoretical mass invoked by scientists to explain galactic rotation is simply normal cold matter we cannot see.

A tiny minority of scientists have speculated on more unusual material as a potential cause, but you must understand that they are a minority and their work is pure speculation with no basis observational evidence.

IOW dark matter is almost certainly simply normal matter that for some reason isn't emitting above the 4^oK background. Or more simply dark matter is just regualr cold matter that we can't see

>>>>So what's the prediction of this ?

The prediction is that it exists. That is the only prediction made.

>>>>ammount growing, shrinking, stable or yet not examined ?

Given that galactic rotation is stable (and all the evidence suggests it has been stable for over 10 billion years) we have to assume it is a constant mass.

Answer 3

Regular Matter makes up 4% of the universe, Dark Matter makes up roughly 25%, and Dark Energy makes up the rest.

Answer 4

The dark parts of universe probably simply don't exist becouse I belive that is all filled with galaxies but there shure is the lots of empty space.

Answer 5

considering you cant see it, then the answer is clearly, NO ANSWER. i would bet infinity dollars that no one will ever be able to answer that question
