what s the osc illating theory of universe?

the oscilaating theory of the universe is the theory on the universe expanding. The gravitational pull of all the galaxies plus whatever the other matter existed in the universe would be great enough to slow down that expansion or even reverse it.

Can you please rephrase this to something I can understand clearly, thanks

In the oscillating theory of the universe, it is expanding at the present time (following the "Big Bang") but gravitational forces are so strong that the burned-out galaxies will eventually reverse and come back together in a "Big Crunch" that will reignite another expansion.

Recent measurements indicate that an unknown repulsive force is causing the expansion of the universe to accelerate. If this is true, the universe is not expected to oscillate.

Stay tuned. No one really knows

thank you drwls, I appreciate your input :-)

Sure! The oscillating theory of the universe suggests that the universe goes through cycles of expansion and contraction. During the expansion phase, the universe gets larger and galaxies move farther apart. But eventually, the gravitational pull from all the galaxies and other matter in the universe could slow down or reverse this expansion, causing the universe to contract again. This cycle of expansion and contraction would repeat over and over again.
