on causality and The Big Bang Theory
Asking here in layman's terms..
When theoretical physicsists discuss the origin of our Universe, the wider consensus appears to be that it originates from a singularity; a position that rests on observations about the apparent expansion of our Universe.
However, the question why singularity itself came into being, still remains.
But this question takes a different angle: Does the Universe as a whole need a cause to exist at all?
If the law of conservation of energy is universally valid, then questions about a beginning become irrelevant since there can't be any by definition and everything boils down to dynamics of interaction. Thoughts?
