Guys,
I have a question about looking back in time to the beginning of the big bang.
If you assume the universe is infinite and expanding, then i don't understand how we can see light from 500 million years before the big bang.
When the big bang occurred (save for an event horizon that may have occurred when there is a singularity) light would be traveling at the constant speed that it does.. therefore:
a. how come the light wasn't lost
b. does this mean the universe is expanding faster than the speed of light.
If you could place at yourselt next to the big bang, then after 1 sec the light would have traveled hte usual 186,000miles, therefore if the universe was not that big wouldn't the light have been lost forever.
Additionally, in an infinite space there is no centre, then how can we know to look in the right direction, i mean, if we look left and see cosmic radation 18 billion years old and see the same if we look right how does that work.
Cheers
