Theory of relativity Background Theory of relativity which was announced by Einstein is theory of physics. It is commonly called relativism for short. It has six phenomenon. 1th, nothing is faster than light. 2th, The object which moves almost the same as light can looks shrinking. 3th , the object has an energy which is equal to the mass times square of speed of light. That is to say. Perhaps, we can go to the future. Research question Can we go to the future? They emitted radar from the earth toward Venus and capture the reflected radar. Methods We emitted radar from earth to Venus and we captured the reflected radar. There is term which is between earth and Venus. We found out distance between earth and Venus. So , we can calculate time. But, calculation result is more important than the time. Conclusion The much time is corresponded with the calculate of relativism. So, we proved the heavy thing create the space distant.
