Thank you, I will check out the link.
I guess what I am asking is a matter of perspective. If we are only on one side of the earth and the force of the earth moving is what holds us to the ground then to me it doesn't seem to be very important which direction the earth is actually moving just so long as our back are against the wall and facing the direction in which the earth happens to be moving. I guess I am thinking of something like centrifugal force. Or like the feeling you get whenever you are in a car that has a lot of horse power which can take off at a high rate of speed...as the car accelerates forward it is moving faster than your body at that moment, you feel your body being pressed against the seat.
So to me, lets say if the earth wasn't moving up and we jumped...then we would never "fall" because the earth would not be moving to catch up with us. In my mind it works the same way if we are facing down. The downward moment of the earth moving faster than our own body after we jump would be the same wouldn't it?
I don't know if I am explaining my question clearly. I just don't understand why the earth necessarily must be moving up.
I'm not sure what you're asking here. The Earth moves up at 9.8m/s^2, which emulates what you know of as 'gravity'. Round Earth science teaches that gravity is what holds us to the Earth, but it's really an upward momentum that holds us down. We know this to be true because the speed of an object falling freely near the Earth's surface will increase by about 9.81 metres (32.2 ft) per second every second.
