How did the big bang start from nothing?
In: Physics
There is a half-answer to your question.
As long as everything is sum-0, there is technically no reason you can’t get “something” from “nothing,” just as if x=0, x can also equal -1+1.
I put those words in quotations because the concept of nothing is debatable. Physics says even empty space, completely devoid of matter and photons, has energy. It’s actually ripe with virtual particles – the quantum version of a -1+1.
Some hypotheses suggest a phase change could have caused a massive production of particles and energy that still sum to 0 total energy.
