Re: Strong gravity

Gravity dictates the orbits of the planets around the sun. By measuring those orbits, you can calculate the planet's gravity. Here on earth, we have a normal gravitational force.
By the way, the earth's gravitational pull does not "twist" something in orbit - the force it exerts is directly toward the center of the earth, and would be the same whether the earth was rotating or not.
