The Theory of Relativity, Updated

Watch this video on YouTube...the woman has this funny theory. She starts out asking, you do know what H2O is? You have heard of Einstein. Basically she notes

1) E=mc^2
2) As the diameter of protons, neutrons is about 1E-15 m, while the diameter of the atom is 1E-11. Thus, all the mass in the galaxy would fit into a small ball.
3) Thus, the mass being small, we can ignore it, and so E=c^2.

This plays into her theory that we are all mere energy, which somehow means homeopathy works.

Only using mere words can one can make this mistake.
