Why couldn't it just be here all along? Nihil ex nihilo, after all. |

Cool, the big crunch was what I meant :) Didn't realise it had a proper name :p |

The universe is ever expanding at a faster rate (Red Shift). I think a crunch is out of the question.
and no, this isn't a religion thread..:rolleyes: |

| Like homer simpson said, think of the universe as a donut. You walk around the donut all day, but you will never reach the end. You can travel in all axis, but you will never have a beginning or an end. But if you want to escape the universe, all you have to do is come with me. Take my hand and fly away with me, Over mountain and sea, Far away from the pain to a place where we're all free. As we fly together, you and me, We will build a new world We'll believe in a love I know that we will be Together and free. Together, forever, Move on to an island across the sea |

If the universe has a beginning, how could matter and energy have been here all along? |

What if there was a black hole (or something similar) that was so large and so dense that it slowed the expansion, and eventually reversed it? Is something like that possible?

That's why the 'cyclical' theory makes more sense (to me anyway :p) |

1) The universe doesn't have to have a beginning
2) yukii's "outside the universe" . theres nothing "outside the universe". whatever it "outside" is part of it.
3) from a distance the gravity from a black hole behaves the same as a star of equal mass |

okay, so if there was no beginning then youre saying there was no starting point?
