True.
I did watch a show on Discovery Channel last week though and they were pretty much discussing the Big Bang like it was fact...I sort of went... :shrug: ok. They said that like...30% of the static on a TV (analog signal I think) was from "leftover radiation from the Big bang". or something along those lines. I found something more interesting to watch though after like 15 minutes
Haha, yea, well, its kind of like gravity. Gravity is a fact, right? Well, not really. Since it is based on the general theory of relativity, it is not a fact.
Yet, we know enough about it to kind of call it a fact. Ya know?
Kinda like we KNOW for a fact that if we throw a ball up, gravity is going to pull it back down and we call that gravity. Same way we KNOW that at one point in time everything was very very close together (note I did not say "infinitismally small point" since THAT is the theory) and it expanded into what it is today. We KNOW that. We just don't know all the details.
