Essentially yes, a supernova shock wave pushed enough nebulous material together to form our solar system. |

Well what you said is wrong.
Supernova explosions would scatter material away from where it was formed, and then GRAVITY would pull the material together, not a "supernova shock wave". |

May be you are misunderstanding what I said. There was already nebulous material at a great distance from the supernova and the blast wave pushed the material close enough together to jump start our sun. Please don't argue semantics with me, if you don't believe me I don't really give a . |

all this sounds fascinating.. I always wanted to know how do they actually figure out how wide and far away planets or stars are with just a telescope?
wouldnt you lose depth perception when your looking at something so far away. what is the frame of reference?
Im not very knowledged in this subject so maybe someone could explain it in basic terms. |

What, so you can play Playstation, drink beer and watch hockey on a spaceship as it hurtles towards some distant planet? I can just see it now; your girlfriend at the window and you saying "I'll come and look later..."
Also, I think this short story is highly relevant to this thread, and everyone should read it. It just proves why Isaac Asimov is one of the greatest science-fiction writers ever.

Oh but I will argue the semantics with you.
Now you have put it like that, yeah supernova blasts could push material closer together. But still, gravity is responsible for the creation of the sun and solar system. If anything, the blast would have only helped initial conditions. |

That's exactly what I meant I just didn't elaborate on it. I figure e=mc˛ doesn't really need explaning, but thank you for clarifying it for anyone who just tuned in from american idol. |
