What prevents scientists from being able model what was before the Big Bang?

Answer 1

Literally none of these answers answer the question.

The real answer is scientists look at light to tell us what happened in the far distant past. This is because light takes a long time to travel vast distances so looking back is literally looking back into the past. The furthest we can look back is cosmic microwave background which is what tells us that a huge big bang happened.

Problem is we cannot see behind that cosmic microwave background. In this [image](https://static.wikia.nocookie.net/kardashev/images/6/6c/CMBR.webp/revision/latest?cb=20210619193524) imagine you’re standing at the “present” point and looking back into the past. You can see all the formation of galaxies and stars right up to the big bang but you cannot see behind the cosmic microwave background so it’s a mystery as to what happened before.
