Question submitted by Jeff of Williamston.
Gravity is an attractive force between objects.
Objects with more mass will experience a stronger attraction to each other. The farther away these objects are from each other, the less they will be attracted to each other. Albert Einstein suggested a slightly different definition of gravity. Lets imagine that the universe is like one big, flat piece of foam padding. If we put a heavy steel ball on the foam it will create a depression in the foam around itself.
