What would the Universe have looked like before the Big Bang?

Answer 1

My surmise about our mysterious universe before Big Bang (BB): Perhaps 27.6 billion years (by) ago, our universe might have existed like what it is now.

Based on my hypothesis, there is a BB-BB cycle with a period of roughly 20 bytes.

This is divided into two-half cycles.

(i) the condensation and integration of matter into a single, infinitely powerful source

(ii) breaking down to produce an expanding universe.

The question doesn't have a scientific answer.

To the best of our knowledge, there is no way for us to access what might have existed "before" the Big Bang; all we can speculate about lacks scientific validation.

The universe was infinitely dense, hot, and small prior to the Big Bang, a state known as singularity, about which our knowledge of physics breaks down. Thus, it is impossible to describe the appearance of the universe at that time.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
