Yes, there are proofs. Pictures from stars during an eclipse show that a light ray does, indeed, bend near gravitational fields (a consequence of the general relativity theory).

Evaluating a Lorentz transformation Special relativity Physics Khan Academy YouTube
Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper " On the Electrodynamics of Moving Bodies " (for the contributions of many other physicists and mathematicians, see History of special relativity ). Special relativity is based on two postulates which are contradictory in classical mechanics : Our modern understanding of gravity comes from Albert Einstein's theory of general relativity, which stands as one of the best-tested theories in science. General relativity predicted many phenomena years before they were observed, including black holes, gravitational waves, gravitational lensing, the expansion of the universe, and the different rates clocks run in a gravitational field.
Learning Objectives By the end of this section, you will be able to: Show from Einstein's postulates that two events measured as simultaneous in one inertial frame are not necessarily simultaneous in all inertial frames. Describe how simultaneity is a relative concept for observers in different inertial frames in relative motion. Bettmann/Bettmann Archive. Albert Einstein would have been 139 years old Wednesday. Happy Birthday! Einstein's science, and general views on humanity, have profoundly changed the way we see.

special theory of relativity. theory that Albert Einstein proposed in 1905 that assumes all the laws of physics have the same form in every inertial frame of reference, and that the speed of light is the same within all inertial frames. speed of light. ultimate speed limit for any particle having mass. time dilation. Relativistic momentum p p is classical momentum multiplied by the relativistic factor γ γ. p = γmu, (13.6.1) (13.6.1) p = γ m u, where m m is the rest mass of the object, u u is its velocity relative to an observer, and the relativistic factor. γ = 1 1 − u2 c2− −−−−−√.
