He was the first scientist who demonstrated that time is a key element in the laws of movement. The legend says that, during a boring religious ceremony ,Galilei was swinging a lamp and thus discovering the principle of the pendulum watch, in June 1637.
He founded his theory about time in 1686.Newton considered that the entire mechanism of the universe is the same to that of a clock watch and that its parts are moving with mathematical precision, determined by fix and predictable laws. Newton's time is absolute and universal, the same for everyone and it doesn't depend on the way individuals move.
He demonstrated that a finite universe that is expanding can have a beginning localized in time- thus recommencing Saint Augustin's idea. The mathematical model used by Friedman to explain the expansion of the universe is the first theory in which the term Big Bang is used.
The man who revolutionized Newton's theories and demonstrated that time is not absolute and universal ,but on the contrary it is relative. So time is different for everyone if we move at different speeds, because time dilates by movement. As Einstein said: "...the past, the present and the future are just illusions ".
He showed that Einstein's theory about the relativity of time involves a non-detachable link between time and space- notions that cannot be separated.
The physicist that invented and defined the term "black hole". He considers that black holes are like infinite webs of time-portals to eternity. "Time is the way nature made sure that all things do not happened at the same time" ,he said.
