Science can explain why we value things, but the same goes for values we reject as wrong. That's why scientific explanations of what we value cannot … - Alexander Rosenberg

Here is a list of some of the questions and their short answers (...) The interesting thing is to recognize how totally unavoidable they are, provided you place your confidence in science to provide the answers

Why is there anything at all? or as the question is famously put, Why is there something rather than nothing? Physics, especially quantum physics, shows that the correct answer to this question is: No reason, no reason at all.

A hundred years ago, it became clear that most events at the level of the subatomic are random, uncaused, indeterministic quantum events—merely matters of probability. Locate an electron on one side of a steel barrier it doesn't have the energy to penetrate. There is some probability that the next time you detect it, the electron will be on the other side of the barrier it can't penetrate. But there are no facts about the electron that explain why sometimes it does this and sometimes it doesn't. At the basement level of reality, there are just probabilities.
