Re: About planetary gravity

Wow. That sounds horrible.

I had an idiot science teacher in 7th grade who insisted that atomic bombs are more powerful than hydrogen bombs because atomic bombs are fission, which throws things outwards, and hydrogen bombs are fusion, which is an implosion that sucks things inwards. I sat there thinking, "That's so stupid it's not even wrong!"

Gravity is an attraction between two masses, with the formula Force = G * M1 * M2 / R^2, where M1 and M2 are the masses of the two objects, G is a constant, and R is the radius between their centers.
