- I have seen scientists everywhere support the Big Bang Theory but I don't understand how it is possible. Why didn't the universe just collapse into a black hole. I also don't see why our observations can't be explained by other phenomenon.
Main Question or Discussion Point
I don't understand how observations of the universe and theories behind the cosmos support the Big Bang Theory. For example, the microwave background could be explained through different mechanisms in space. Couldn't the red shift in galaxies be explained by something that occurred in the galaxy? Assuming that red shift does mean that galaxies are moving away, could it be a local phenomenon? I also want to know if there are other observations that I don't know about that support the Big Bang Theory. Please help me understand why the Big Bang Theory is so popular.
