What came before our Universe?

Answer 1

We don't know !

Space-time emerged following the Big Bang,

The Universe's current shape and characteristics were brought about by an unraveling of symmetries caused by a perturbation in the quantum foam.

Before the Big Bang space-time was a singularity, and the critical point was the Planck Time, #10^-43# seconds,

An unknown state of the universe is symbolized by the abstract idea of a singularity.

The question of what came before our universe is a topic of speculation and debate among scientists and philosophers. Some theories suggest that our universe emerged from a singularity in a cosmic event known as the Big Bang, but what, if anything, existed before that event is still unknown. Other theories propose the existence of a multiverse or cyclical universe, but evidence for these ideas remains speculative. Ultimately, the question may lie beyond the current scope of scientific inquiry.

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.
