Here's my 3 cents worth (3 not 2, inflation you know...)
I do think that there was some sort of a big bang all those years ago. Maby because there is a maximum size a black hole can have beyond which it goes BANG causing a big bang episode . However I'm also convinced that the universe was already full of stuff scattered all over the place. Things such as black holes and galaxies were already floating around. In other words the big bang was not the beginning, it was more like a messy rebirth or recycling event. Also, trying to explain any of this with religion will only lead to mas hysteria and human sacrifices 😬😁.
I have to run, there are people outside with pitchforks...
But first, here's my question; shouldn't we be able to look far enough into the past to a point and time on the far side of where the big bang took place (in relationship to where we are) and see the actual explosion?
These thoughts give me a headache.....🤯
