  1. wat are you smokin


  2. Up to that point in time, the universe was nothing more than a super-hot, opaque kind of plasma.

  3. Sorry miss read the question. Yes I would have to agree that before the universe as we know it  expanded out far enough to be identifiable as multiple fragments temperature or no it would have appeared if anything as still one massive star. Perhaps even at a frequencie of light that we can not detect such as infrared or gamma ray

  4. because light is caused by the excitation of an electron around an atom. when it excites it jumps up an energy level. to become more stable it jumps back down to its ground state and releases a photon. for the first 380,000 years the universe was too hot for electrons to orbit around protons and form the first hydrogen atoms. prior to that electron energy levels didnt really exist.

  5. ?????

    Oh, you mean the temperature thing.

    The Universe's temperature dropped below 3,000 degrees. Electrons began to slow down enough to be captured by protons, thus bringing atoms into the world. With fewer unattached electrons to gum up the works, the photons could finally race around without bumping into anything. That's when the universe became transparent, the fog lifted, and a cosmic background of visible light was set free.

    Before that, there was nothing that we could see.

  6. because tivo dosent go back that far ; )
