The Universe didnt happen at a certain "point" or any particular "place". Space exists when matter is present, that's all. Even though space is "empty", our definition of space is wrong, since even empty outer space is full of virtual particles coming in and out of phase and annihilating each other.I got a question for you guys/gals. The universe is said to be 14 billion years old... I read somewhere that the farthest image ever taken from a telescope was 12 or 13 billion light years away. If they could reach 14+ billion light years would they then be viewing the big bang? Because the image they see will have happened 14 billion years ago, at the so called beginning of it all. Or would they just see a mirror image of themselves looking through a telescope?
Picture a balloon. We're on a point on that balloon. When the balloon gets bigger, or inflated, there really isnt any point in which is really the center of the expansion. That's why we cant see a mirror or anything like that, because there is no center to see because the Universe isnt from a point in any particular place (or time).
Light didnt get visible till about 400,000 years after the Big Bang. It took that long for it to cool to 3000K which is the temperature needed for electrons and protons to combine forming neutral hydrogen. Neutral hydrogen absorbs photons so the Universe is opaque. When electrons and protons separate the photons can creep through making the Universe (like it is now) pretty transparent.
