Theory dealing with how massive object bend or warp space and time around themselves.
Theory dealing with the effects of motion at near light speeds.
Postulates of Special Relativity:
Two fundamental assumptions that form the basis of the theory of special relativity.
Physics based upon Newton’s laws. These laws work very well for motion that is not near the speed of light. This physics is inaccurate for near light speed motion.
Physics that describes the behavior of object that move at nearly the speed of light. At low speeds, it simplifies to agree with Newtonian physics.
Any new theory must agree with an old theory when the old theory gives a correct result.
The slowing down of time in a frame of reference moving at relativistic speeds.
An apparent contradiction where one twin takes a high speed trip and returns with a different age compared to the other twin.
A subatomic particle with a very short life span. When moving at very high speeds, it seems to exist for a longer period of time. This is one experimental piece of evidence that supports the theory of special relativity.
The shrinking of a distance or length due to motion at relativistic speeds.
The energy of mass itself, as given by the equation E=mc2
Frame of Reference:
A viewpoint or set of coordinate axes to which position and motion can be described.
