If the hypothesis that the universe goes infinite cycles of bang and ending. About how long after an ending until a new bang to start again?

Well, that *was* a theory for a very long time; Once the Big Bang was discovered, it was thought that the gravity of all the mass from all the galaxies in the universe *must* be slowing the expansion. The big question for years was, will it stop? Or expand forever?
25-30 years ago, when we finally were able to measure the rate of expansion, it was a surprise to most that it was, in fact, *speeding up.* Today, it looks like the expansion not only won't stop, but will keep accelerating. "The end of everything" is looking more and more like it might be "The Big Rip."

that could be a single instant, or a very, very long, time.
speed and time and mass seem to be existing and non-existing in various ways; using math, it is even more complicated.
the buddhist theory is that in an infinite amount of time, that the universe has existed in life and death, millions and billions of times. with cause-and-effect, this universe manifests, and life occurs where an environment forms.
my math is: 1-universe = 1-universe; winter = spring; monday = tuesday.
cause and effect exists.

Instantly. The final crunch would be the big bsng of the next cycle.
Also, if the universe collapses to a singularity, time ends. So time would not flow until the next bang. There is no time passing outside of the universe.

So what started the endless cycles, and why? Doesn't really explain much, does it?

I believe Hawking tried to show this and we simply do not know for the many billions if not trillions of years of such cycle.
The universe is vast with an unbelievable amount of mass. As all this mass looses its energy and collapses back to a singularity, it may begin a subsequent 'big bang' at that moment. This is one of the more viable theories, like a cosmic heartbeat, but each beat taking this tremendous time by our standards.
Already shown is our present universe is far older than thought, but to cosmological time, very short lived.
Why tine is considered a temporal dimension.
Steven Hawking and Neil Tyson both wrote papers on the matter, very interesting reads.
