Gravity is interesting, how and at what speed does the earth move that keeps us attached to it.??
Why do we on the a spinning object not notice the spin of the earth, true we are born into a grativitalion field, we know things do drop into the ground, but to us we in the middle notice no movement , we do not fly into the air, how is the weather brought into all this planet gravity.??
We know all about gravity holding the moon in place our outer planets staying in their place, so, this system is stable all due to spinning objects and their Mass. Mass generates some kind of gravity,
Then one takes a bucket of water and places say, balls of doe on the sides and spins it in the air, no water is lost, but slow down the spin and the doe falls off before the water slouches out. Ask Mr. Wizard he can tell us why. Then the fact that one is worrking against earths gravity and causing a secont gravity brings more questions into mind.
Give me a break, only few humans can figure this out--or so they think---But the simple humans cannot expect to understand all this, the Math and theroys are above understanding. Fun for us to think about all this on a sub leavel but it would not surprise me if a 8 year old on a computer finds the ansewers and turns science upside down.
