mass ATRACTION

A man named Newton said" Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

In other words,  the closer and larger two objects are, the more they are attracted to each other. Another way to put it is that two large objects that are close together are going to have more"attraction" to get together and smash each other apart. This video demonstrates the power of GRAVITY and the two large objects are the stupid dude and Earth, meaning the rail,that he was trying to grind on. His reaction to gravity is his ***** getting smashed and the other reaction is him screaming, quite profoundly too. The rails reaction was it shaking a bit.
