Nothing comes from nothing. Since the universe is something it must come from something.

You don't know that. Near as we know, the universe did come from nothing. Causality is a pointless question when you consider that time itself was created in the big bang. Furthermore, we can not experience true nothingness...even "empty" space itself is something, so you cannot logically say that something cannot be created nothing.


US astronomers have used images taken by NASA's Hubble Space Telescope, to capture massive supersonic jets streaming from newly formed stars.

The jets are travelling at an amazing 700,000 kilometres an hour, creating powerful bow shocks that light up the molecular gas and dust clouds in which the stars form.

The correct term is hypersonic. Supersonic speeds are significantly slower than that.
