No, I’m not going to start expounding upon my academic pedigree so you can use it to accuse me of being an elitist. That’s what the internet is for, if you care about it.
Anyway, so what if there was some celestial body that once came close to the Earth? What does that have to do with a flood? One has to come up with a plausible physical connection for people to take it seriously. Dean Sessions understands this, apparently, because he tried to come up with a mechanism involving centrifugal force. That proposed mechanism cannot be correct, because it is only even hypothetically possible around the equator. Can you at least do enough research to confirm that centrifugal force becomes smaller and smaller as you decrease the spin radius? All you have to do is swing around a small weight on a string, and note that the weight tugs on your hand less and less the shorter the string is (assuming the time it takes to go around remains constant. If you can confirm that much, I would be happy to move on to discuss something else.
