Big bang

 
They say that a microsecond after the Big Bang the universe was as big as a galaxy.

How could this be if nothing can exceed the speed of light and a galaxy is maybe a hundred thousand light years across?

The big bang is not an explosion in space, as it is often imagined to be, but rather, it's an expansion of space itself.

The speed of light limit applies to objects moving within space, but it does not apply to space itself. Sci-fi writers take advantage of this to imagine machines capable of minipulating space itself so that faster-than-light travel/communication can be achieved without violating relativity.

I dont know what 'big bang' your talking about
but the big bang is a myth about what happend to the dinosaurs
the giant meteorite that hit the earth and suposedly killed all the dinosaurs is referredd to as 'the big bang'

jaz, you couldn't be more wrong. The Big Bang theory is a model describing the expansion of the universe.

I do not know the answer to the original question but I do wonder if perhaps the laws of physics as we know them did not apply. After all, these laws apply to the universe as we see it now and not necessarily to whatever 'existed' before and during the expansion.

I really don't believe in the big bang theory. nor the religious theory's. I'm going to pretty much wait to figure that out a couple of years down the road.

Good Question...Speaks a lot to our current definition of nothing doesn't it? Always seemed weird to me that nothing could even have a definition.
