Big bang cycles

If you interpret the red-shift data to mean velocities of galaxies, then the universe actually has begun accelerating outward after a period of initial gravitational deceleration, so by this interpretation it looks like the answer is that there are no cycles.But this is an odd way of looking at it especially since quantum mechanics has discovered that space is a sea of energy in the form of planck particle pairs. So if space itself were expanding and the zero point energy were becoming less dense, the light would actually experience a blue shift en route.But the doppler shift interpretation of red-shift data has run into more and more problems, so other interpretations should be sought.

Amen to that. Thanks for the websites.

Are they bad because they are not mainstream or do you actually have reasons for calling them bad?And... Do you think big bang cycles exist? If so, why? If not, why the big bang?

Well... It's been a while since I read the Elegant universe... But yes, I think so.What I said before may have been confusing as I am reporting second hand what I have read elsewhere:If the ZPE were decreasing light would experience a blue shift en-route but a redshift from it's emitter. If ZPE were increasing light would experience a slight red-shift en-route but a blue-shift from it's emitter.
