Since the univerise is considered expanding- when does the rebound start?

Answer 1

There is no rebound.The most current astronomical information states that 3 or 4 big bangs have occurred in our known universe.When these universal membranes touch every few billion years,the result is a blast of matter in one direction and anti matter in another.We are in the expanding part of the matter blast.Over time the expanding matter will collide with the other side of universe.We don't really no what will happen then...tom science

Answer 2

Does it have to ever rebound? I don't think of the universe as a mass, but as a space containing various mass. So if the universe is a space, and what's really expanding is the SPACE between all the mass, then why does it ever have to stop? Of course, if the universe represents all of space, you have to wonder what it's expanding INTO (the Notspace, maybe?), but that just makes my head hurt.

Answer 3

theres 3 different sets of math for the universe:

1)Math "A" says the universe is expanding, and physcial evidence does support this.

2)Math "B" says the universe is in a "steady state" and is neither contracting or expanding.

3)Math "C" says that when the expansion of the universe is overcome by the total gravitational pull of all the mass in the universe it will begin to contract.

Nobody really knows if "C" is viable; "B" has been pretty much disproven since the 1950's, and physical evidence supports "A"

Answer 4

It doesn't necessarily -- expansion could continue indefinitely. The subject is of considerable current interest to astronomers, who are busily seeking data that would help answer this.

Answer 5

Day after tomorrow.
