Quote from: Bill S
Then there is Mark McCutcheon!!! He believes there is no gravity. He believes that all the matter in the Universe is expanding. If we drop something, what we perceive is not that object falling to the ground, it is the ground coming up to meet the object.I heard this back in the sci.physics newsgroup many years ago. I explained to that person why he was wrong (i.e. what observations of the world around him contradict his claim) and I was promptly ignored.
Suppose he was right. Then the earth would be getting larger and larger and larger while the same thing would be happening to the sun. Since, according to him, there’s no gravitational force both the earth and the sun move in straight lines. If what he said were actually true then both the earth, moon and the sun would be getting larger and larger with time. That means that the surface of all three of those heavenly bodies would be getting closer and closer to each other. Since observation tells us that this is not the case it follows that Mr. McCutcheon is quite wrong. However I doubt he’d admit it.
People like that must truly think that each and every physicist in the world is an absolute moron.
