What was the universe immediately before the Big Bang occurred?
1 answer
The concept of "before" the Big Bang is somewhat challenging to comprehend because the Big Bang marks the beginning of spacetime itself. According to the prevailing cosmological model, the universe emerged from a singularity—an infinitely dense, hot, and small point. Prior to the Big Bang, our understanding of the universe's state is limited, as the laws of physics, as we know them, do not apply to this extreme condition. Therefore, the nature of the universe immediately before the Big Bang is not yet fully understood, and it remains an area of active research and theoretical speculation in cosmology and physics.
