What is Gravity, according to the world
Gravity is a fundamental force that attracts all objects with mass or energy towards each other. It's the force that keeps planets in orbit around stars and objects falling towards the ground. Essentially, anything with mass has gravity, and the more massive an object. You are expected to believe a spinning ball hold billions of tons of water as it flies round the sun at 67,000 mph. Boats, people, planes etc on the underside of the spinning ball are being held on with gravity and would be upside down compared to the people on top of the ball. Does this make any sense? Please also remember Gravity is only a theory as is the Big Bang, Evolution, Relativity & Special Relativity.
What is really going on
Gravity is a theory required to make the spinning ball idea work. There is no need for gravity on a flat stationary earth. Objects fall as they are heavier than air and rise if lighter than air, in water we have buoyancy allowing objects to float. In short we have the natural forces of buoyancy and density, objects rise or fall according to the relative density of the medium surrounding them. If we also had gravity trying to hold everything down to the centre of the earth we would not be able to move, butterflies could not fly and birds could not dive into water, catch a fish and fly back out. There is no need for a theoretical force on the flat stationary earth. Google "Is Gravity a Theory".
