I think my problem accepting the BB explanation for the Hubble redshift, is just I'm too grounded a person in my thinking. The idea of an expanding universe just doesn't make sense to me. (as opposed to the idea of a universe of infinite size that's always been there)
So, I guess I want to rehash tired light theories until I have absolutely no choice but to accept the BB, in the hopes that doing so will make it easier for me to digest and accept.
Then all the physics that builds on it as a foundation will be accessible to me, which would probably help me in completing my study of it. I seem to have a hard time learning things if I don't believe them at least a little.
