That was fun, if a bit long.

Devious, treacherous, murderous, neanderthal, sub-human of the West.

Found this today: How the universe appeared from nothing

Short version: it may not have. It may still be nothing, in terms of physics.

Quote
Due to the weirdness of quantum mechanics, nothing transforms into something all the time. Heisenberg's uncertainty principle states that a system can never have precisely zero energy and since energy and mass are equivalent, pairs of particles can form spontaneously as long as they annihilate one another very quickly.

The less energy such a system has, the longer it can stick around. Thanks to gravity ? the only force that always attracts ? the net energy balance of the universe may be as close to zero as you can get. This makes its lifespan of almost 14 billion years plausible.

Devious, treacherous, murderous, neanderthal, sub-human of the West.
