elcaro - your post regarding 'taking the bang out of the big bang' was super interesting not just because P Steinhard was a great proponent of the big bang and has now changed to a cyclic concept but importantly the theory as he explains it does not have any of the problems associated with...
Looking through the various most popular theories (or conjectures, thanks Buzz) I struggle to find one that seems to allow for the super massive black holes that were reported to be formed by Smethurst at around 670 million years from the start of the universe. Super massive BH being around 1...
Thanks ohwilleke.
Penrose and his cyclic cosmology proposed that all matter ends up in black holes, what happens to those black holes depended on the duration of the universe and it needs a long long time to meet the cyclic conditions of decay by Hawking radiation.
Penrose and Loeb (the...

Never heard of Smolin's theory so any details about that would be fun even though discredited.
I have heard of and read about the big bang theory for the start of our universe. Are there other competing theories that I should look at.
Thanks

Hello berkeman
I made post that was deleted and called personal speculation. Maybe I should have asked if the start of the universe could have been a collapsed previous universe. That is not speculation but a question.
May I re write my post in a better form as i am still interested in peoples...
Hello all
Glad be here and now I have retired it is a favourite place to browse. Many years ago I was involved in nuclear industry and worked on the nuclear submarine reactors hence my interest in physics.
