It varies based on a lot of factors, and obviously gravity is not the same everywhere. But since we can obtain practically all the info needed, we can predict exactly what will happen, how fast it will happen, etc. How do you think we can slingshot space shuttles around planets with pinpoint accuracy? Luck?Define the true and exact properties of gravity for me.
this is trueNo, rocket propulsion allows us to do that. If we understood it perfectly, we could do without said assistance.
I'm not debating with you that we don't know wtf it is. I'm say we don't know exactly how it works.
