This tells me all I need to know right here. The big bang is not a fukking explosion. EXPANSION IS NOT AN EXPLOSION. Go read some god damn books breh. fukk.
and yes, the accelerated rate of expansion is puzzling to scientists, go read up on Dark Energy.
Whatever word you want to use. It was a catastrophic event that resulted in the rapid expansion of the universe. "Explosion" is just an easy and understandable way to say all that.
And once agin "expansion" "explosion" or whatever you want to call it should not speed up according to what we know about physics. Dark energy is one theory, and there are plenty of others. Some may slightly alter the Big Bang theory and/or our understanding of physics. Some could totaly change what we know. I don't know why me stating that fact, gets you so angry.
