When big bang happened our universe had created and at that time there was no matter but only energy , will any one explain then how matter was formed from it ?

 

 

And at that time what energy looked like I mean in empty universe how can u tell that here is energy and this is energy , was energy present as sort of some particle or something else ?

Why not have a little fun and consider an alternative to the big bang?

 

Big bang doesn't describe a beginning, just a change in state. But before the bang? What caused the bang? No answers.

 

Posit the universe consisting of only bosons and objects made of bosons. Sort of like today, only different, and, like today, not in a steady state. Something changed, just a bit, just enough to cause fermions to precipitate out of the bosonic environment.

 

No need for a singularity. No need for a particular central starting point. Just a process sort of like condensation in the atmosphere, happening everywhere more or less all at once.

How does this fit in with all of the other evidence that supports the big bang? How do you get e.g. expansion and the CMB from a bosonic universe?
