No. But we don't know what was going on before the big bang. My theory is it was a dead old previous universe after the last star died. So nothing but darkness and then all the rocks and diamonds and everything collapsed back in on itself and started a big bang.
Remember, if you are a fan of the big bang, consider this. It started off really small right? So at one point the observable universe would have only been 1 light year across. Correct? I mean in the way back beginning. Today what is it 900 billion light years bigger? Point is, our observable universe is much bigger than it was when it started. So it's eating into something. That something we are eating into at the edge. It just keeps getting bigger and bigger. So every day our observable universe travels into the Universe that you claim doesn't exist.
I thought about you last night. You're an intelligent fish in a fish bowl. From what you can see, the room was made for you. And there is even a god who feeds you and provides everything you need. Seems like the world was made for you. But the universe can't be bigger than the room you are in. You see god leave the room but only god can leave the room. Because he's outside of time and space.
AND he has talked to you. LOL.
