Arguably mankind's greatest achievement and the technology is destroyed?
astronauts mix up their facts (one said stars were bright and lit, other says it was a deep pitch black no stars)
Nobody takes a picture of the earth from the moon
gravity is a theory and is not provable. Fact.
That a force pulls us to the Earth is a fact.
We call that force gravity, but it really doesn't matter what we call it.
That the force obeys Newtons law of gravity (F=Gm1m2/r2 in which F is the gravitational force, G is a constant, m1 and m2 are the masses of the two objects, and r2 is the square of the distance between the objects) is also a fact.
The explanation of why gravity works is a THEORY which can never be proven. But that the force we call gravity exists and obeys Newton's laws are both facts.
