Question from Steve R:
If the big bang was an inevitable consequence of the laws of physics, please tell me: which law of physics supports spontaneous creation? I have not found any laws or principles of the physical universe which support the idea of bridging the infinite gap between non-existence (quantity zero) and existence (quantity one) using no previous resources. In fact, I think it’s the opposite – there is a law (and a quite significant law) which clearly state that both matter and energy cannot be created or destroyed (1st law of thermodynamics). If there was no one to make this law, then it is just part of the universe. But if it is just part of the universe, then the universe would have to violate its own laws to create itself. So please tell me, again: which law of physics supports spontaneous creation?
Answer by SmartLX:
No law so far, but multiple scientific theories. Lawrence Krauss regularly talks about quantum mechanics spontaneously generating matter and anti-matter, which have a combined energy of zero when there’s the same amount of each, from a previous state which can be called nothingness. (Something can come from nothing, he says, because “nothing” is unstable.) In Stephen Hawking’s book The Grand Design Hawking makes a claim based on both quantum mechanics and relativity that gravity creates universes and this is only one of them. I recommend reading the work of both to get some idea of the mechanisms science has actually proposed for what you call “spontaneous creation”.
All this may be moot, however, because there is a much simpler solution. As you say, the law of conservation of energy based on the first law of thermodynamics isn’t concerned with the above and states unambiguously that matter and energy cannot be created or destroyed. The universe would therefore have to violate the law to create itself, but if it exists now then the law implies that it has always existed in some form, and it wasn’t created at all.
The idea of anything creating itself from nothing is absurd, because it would mean that the effect existed before the cause. For the idea to make any kind of sense it needs to be an emergence or formation from nothing. Once you get away from the word “create”, it stops being a contest between creation by an intelligent being such as a god and creation by unintelligent phenomena, and seems much more plausible in the absence of a god. This is of course why religious apologists use variants of the word “create” even when they refer to natural hypotheses.
