Gravity increased? LOL. Wow. Some people really WILL believe just about anything.
So, you are saying that mass has nothing to do with gravity?
True. For instance the big bang theory, and declaration by scientists that the Universe was slowing in it's expansion and would eventually all come back together and collapse into a singular point of nonexistence.
Or the even older theory that the Milky Way WAS the entire Universe.
How about this one? Our atmosphere is mostly made up of oxygen. Just ask anyone.
