Isaac Newton - isn't he the guy who discovered gravity? Great! So, what's gravity? Aaaah, gravity is the force that makes objects fall towards the ground. And, without gravity, we'd all float!
Scientists push the limits of quantum mechanics, discovering light particles that exist in 37 different dimensions.
Well, it depends on the size of the objects causingthe gravity, so, their masses.For example, the force of gravity on themoon is smaller thanthe force of gravity on the Earthbecause the moon is ...
