Since time and space as we know them originated with the Big Bang, according to the standard model of cosmology, questions about "before" the Big Bang are inherently difficult to address with current scientific knowledge. Some theories, like the idea of a multiverse or cyclic models of the universe, suggest different scenarios, but these remain speculative without concrete empirical evidence. The conditions prior to the Big Bang are not well-understood, as current theories and the laws of physics as we know them break down when attempting to describe the state of the universe at its very beginning.
