Cosmology: Inflation theory under attack (Introduction)

by dhw, Wednesday, August 02, 2017, 14:27 (2669 days ago) @ David Turell

DAVID's comment: Inflation explains much of why the universe looks as it does, but not without problems. A cyclic universe gets rid of the origin problem but keeps the Big Bang. It also gets rid of the multiverse. A cyclic universe doesn't get rid of a first cause.

Reblak has mentioned the red shift problem too, and perhaps he will explain this in more detail.

On this forum we have repeatedly discussed the unanswerable question of what preceded the Big Bang if the Big Bang ever happened. The concept of eternal energy and matter as first cause would allow for any number of universes before this one, or for this one itself being eternal and constantly changing.
