Gamma ray burst

[Maulin]

Recently I read an article about a Gamma ray busrt that happend about 13 billion years ago and how the burst is only now reaching us

This Gamma ray burst happened soon after the big bang and the universe was much smaller then. So wouldnt this burst have passed through our part of the universe long ago? unless the universe was also expanding at the speed of light. So why are we seeing this burst now for the first time?

The curent theory adopted by many cosmologists is the inflationary theory, which states that in the very early universe (10^-35 seconds) the universe was expanding at a ridiculously huge pace. This lasted only about 10^-32 seconds. This theory explains many things about the observable universe, including the mysterious uniformity of the cosmic microwave radio background. During the inflationary period the universe expanded from a tiny 10^-26 meters up to 10^24m (100 million light years) in diameter. This is a massive rate of expansion.

WOW!
That answers my question...Thanks.

It just so happens that New Scientist published an article today that deals with the early universe with a little bit of info on inflation. Check it out here http://www.newscientistspace.com/articl...ap-of-the-early-universe-revealed.html

hmm from 10^-26 meters to 100 million light years? sounds like a bunch of crap to me. no offense to you falcon.

It's not my theory so no offense taken - but if you can come up with a better model that fits the data I'd love to hear it.

Why?
