[quote name='Blade']He's saying that we're seeing what happened in the Universe millions, if not billions, of years in the past. So nothing that we are seeing probably even exists anymore, and if it does, it's not in the same place.
Supposedly, the Universe consists of 99.9% Dark Matter, which may or may not just be places we can't see yet. They say it's some viscous fluid that the Universe was made up of already before the entire thing condensed and imploded. Yeah, all speculation.
Infinity would probably be a perfect sphere, wouldn't it? Since every part of a sphere is the same, there would be an infinite amount of points. There'd also be an infinite amount of horizontal/vertical movement because it never ends. The Universe being spherical and infinite sort of makes sense.
The one that gets me is if the whole Universe is just an electron in the cell of some other being.[/QUOTE]
The whole time thing is answered by relativity. It's all relative to the observer. If somebody were to travel at the speed of light from this fire ball to us - billions of light years - at pecisely the speed of light, the traveler would not age. It would be, relative to the traveler, instantaneous. If there were an atomic clock aboard the spaceship, the clock would also indicate that the travel was instantaneous. When he got here - remember, instantly - he would tell us what happened right before he left. However, if we looked in a telescope, we could see that it just happened - except, knowing light's speed we'd know we're observing billions of years in the past, relative to earth. In truth, both are right, it happened just seconds earlier relative to the traveler and billions of years earlier relative to Earth.
A sphere being infinite... I'd have a disagree with again. Measurements and numbers are infinite, but nothing physical is infinite. I mean, sure, there are an infinite number of points on the sphere, but ONLY because our measuring systems get infinitely precise. Decimals being infinite. By the same grounds you could say an 8.5"x11" sheet of notebook paper has an infinite amount of points. Technically, it does, because our measurements of its points become infinitely small. But it's clearly a finite space. I don't really agree with the infinitely spherical movement either, but I think that just lies in the semantics of the terms.
