Gravitation: The Four Fundamental Forces of Physics #3
Hank continues our series on the four fundamental forces of physics with a description of gravitation - the interaction by which physical bodies attract with a force proportional to that of...
==========
Welcome Back to our series on the four fundamental forces of physics. Today we are talking about gravitation, the force that you and I probably have the closest working relationship with. But it's not only what sticks you to the ground, and makes you fall down, it also explains how stars and galaxies form, and it will describe how they die. But even though we can watch it in action, gravitation is much more complicated than it appears. Generally, I think of gravitation in two different ways; the way that Isaac Newton described it, and the way that Albert Einstein described it. In classical Newtonian terms, "gravitation attracts everything in the universe that has mass to everything else in the universe that has mass." And I mean everything fr...
