Please put into words what you feel you are missing.
I went so far down science I came out the other side. So, I am not the one to ask what is common knowledge. Yes, I know what calculus if for, and I do trig in my head.

Probably you are missing that NASA are known lying liars, that lie. They have been caught in so many lies that they should have just closed up shop and quietly walked off a cliff. But, their PR and false narrative team are very good.
