Not really. And saying that there is a cyclic universe doesn't remove the problem of a "beginning" it has simply been pushed back a finite number of cycles.

>> No.4694609

you are forcing the finite aspect there, the whole point is that it is infinite.

>> No.4694622

No. The universe being smaller wouldn't help. Life is unlikely to form that early.

Obviously you haven't actually looked at what a cyclic theory of the universe entails. Every cycle of expansion creates entropy through thermodynamic processes which adds to the entropy of earlier cycles. At the beginning of a new cycle there is a higher entropy density then the cycle before. The duration of each cycle is sensitive to entropy density, thus, if the entropy increases, the length of the cycle increases as well. So going forward in time, each cycle becomes longer than the one before.

If you assume that this cycle has been going on for an infinite amount of time, then the length of each cycle would be infinite, and we wouldn't have a cyclic universe.

>contracted

Unless this is the last cycle, which is some pretty shitty luck if it is, then dark energy says that's highly unlikely.

wat

Anyways, an eternal cycle has no beginning, it's existed for an infinite amount of time and will exist for an infinite amount of time. There is nothing finite about existence except for individual universes.

Read it wrong. I read it as, "Why, don't you?"

Thing is, I can't explain why the Mandelbrot set is a single shape. Shit makes no sense.
