Space is filled with an invisible fluid (ether) in which the planets are carried around the sun by whirling vortices. Theory of matter is that matter is defined by the amount of space that it takes up: if matter is defined by an amount of space, then all space is matter. As curator of experiments for the royal society, he tested theories in many branches of science. It"s the cause of motion both on earth and is space. Earth"s gravity not only holds earth together and causes free-fall, but also holds the. Gravitational attraction increases with proximity to its source: eg. The closer a body is to earth, the stronger earths pull on it. Prior to newton, it was believed: when the sunlight passes through glass, the sunlight is permanently changed into coloured light. Using 2 glass prisms, newton proved: sunlight is composed of the colours of the rainbow.
