Can the rate of "expansion" of the universe exceed the velocity of light in a vacuum ( c = 299,792,458 metre per sec ) but not defy one of the key tennets of modern physics in doing so ? How / why is this possible (if you think it is) ? If so - What is a consequence of this ? |

No, as you cannot change the laws of physics.

Why did you put "expansion" in quotes? What is the universe expanding into anyway? |

^^^ I don't know. I thought that the universe was contracting. No? |

The universe is indeed expanding, that's why everything is in redshift, it's moving away from each other. I think the universe is expanding at the speed of light itself since the big bang. |

^^^ Dr. Noah, Thanks. BTW, we just bought The Fellowship of the Ring and The Two Towers on DVD. Our sons have watched them, and love them. I need to be in the mood to sit down for a film (or more than one film) that is that long. (I was reminded of this by reading your signature.) |

Once you have the time, you won't regret it. Best movie ever in my opinion (all of them) since it is after all one, big story (like DS9)

Were your sons watching the special extend version or the theatrical version? |

The universe is not just expanding, space and time are being deformed. So, what appears to be the speed of light in a vacuum from our reference frame, may not apply at the fringe, or other places depending on the deformation of the universe. Either that or our radar gun needs calibrating. |

True, we don't really understand what happening at the edges of the universe quite yet, it will probably take some time before we really. |

Somerled, Please pardon the slight tangent.
They were watching the widescreen DVD version, with two discs for each film. The second disc is loaded with special features (hours, I believe). I'm not sure that answers you question, however. It had to be the extended version. |

Each extended version comes with 4 disks. Two for the movies and two for the interviews and special features. |

Not to belabor the tangent... The extended version has addition scenes that were not part of the version seen in theaters. It doesn't matter though. Sorry for the tangent. |

The version we own has two discs for each film. As I mentioned, tons of special features are included. Not too bad for a mediocre film at best.
