Hi KiwiPhil,
You might like to have a look at two articles at Space.com (Links are at the bottom). I think that you’ll like these two hypotheses.
You can assess how deep your understanding to the Big Bang theory is, and why it is the most accepted model up to date. However, I think Anton is making a lot of sense in his post number 63.
While I’m at it, in my first post on this forum, I’d like to say hello to all forum subscribers. I hope to benefit from this forum and contribute where I can. And of course, very well done to Fraser and Pamela on Astronomy Cast. I love it, and love your approach guys. Thanks!
