Why we have Gravity\n\nA correct theory of gravity will show us these four (4) things:\n1. It will show us why gravity also acts like acceleration (principle\nof equvalence).\n2. It will show us the actual cause of gravity.\n3. It will show us why gravitational mass and inertial mass are\nidentical.\n4. It will show us the speed of gravitational attraction.\n\nNewton said gravity was acting at a much faster speed than Einstein.\nWhich one of them was right?\n\n\n[URL]http://www.amperefitz.com/why.we.have.gravity.htm[/URL]\nClick that link above if you like Science!
