[_ Old Earth _] Water Reserviors in Space

[Barbarian]

The last time I heard about how the earth formed was a college astronomy class several years ago. Back then the thought was that the earth formed out orbiting gasses around the new sun. That gravity of the mass of elements eventually formed the planets of the solar system. But as far as I was aware ot was out of the elements that made the sun. Not from a shockwave of a supernova. So new information to see if it seems accurate. Ya know?

The Sun was also part of that gravitational collapse, and yes, caused by a supernova explosion. How do we know that? It's really pretty simple. Stars like the Sun are massive enough to fuse all the elements up to carbon. Everything heavier than that must be forged in more massive stars,such as those that become novae at the end of their lives. So every atom in the solar system heavier than carbon, is debris from a supernova explosion.

Other evidence? Yes, there is. We can observe this process happening. Observed supernova shockwaves are observed to cause graviational collapse of gas clouds, and new stars are seen forming at the margins of the waves.
