| Feb 15, 2018 at 19:53 | comment | added | Mike | There are many questions that no respectable scientist claims to have answers to (yet). Among them are some of the "big" questions that religion has historically tried to answer. Questions such as "how did the universe come into existence?", "why is there something rather than nothing?", and so on. Physics simply doesn't have all the answers. There are even "easier" questions that we can't claim to answer (yet), like "what happens at the singularity inside a black hole?" Individual physicists may present hypotheses — but if they claim to have correct answers, beware. | |

The universe is defined not only by the the "stuff" that's in it, (especially energy), but also by the laws of nature that describe it. So while I can't say what event (if any) caused the universe to appear, I think it might be safe to say, despite the possible evolution of the laws and physical " constants" over time, that the laws came into existence at the same time as the universe did. | |
