Thanks that means a lot. We agree again. I called bullshit on Tyler and said that gravity does not select what it wants to hold. If gravity existed smoke would not be able to rise from a chimney it would be plastered to the ground as would we all. We would be smushed by gravity strong enough to hold the massive oceans in place that are miles deep and thousands of miles across. On a flat stationary earth gravity is not necessary. I was saying that when things are heavier than air they fall and that when they are lighter than air they rise, we observe that all day everyday. This thing called gravity is a made up theory to explain why people don't fall off the ball earth, it doesn't hold up to careful observation and scrutiny.
