Special theory of relativity says that in the absence of an absolute reference, different observers may disagree on the time at which a particular event happened.
With this knowledge, how do i explain time travelling? Every observer should be witnessing the same set of events (though their...
Ok, let's just leave out the watch. That was put into indicate that no time has passed as per the wave and it still T1 according to it.
Accepted that there is no absolute space and no absolute time, but there is absolute spacetime and this spacetime does have different events on difference...
According to the theory of relativity only force free objects can be considered true reference frames. In the case of the spaceship moving at a constant velocity, it would have certainly accelerated at some point in the past so as to achieve its current motion, which renders it unsuitable as a...
Since the combined speed of electormagnetic waves can be 'c' and that they travel in space at 'c' leaves no component for time, hence the time on a watch on a beam of electromagnetic wave does not change at all.
With this understanding, assume two stationary mobile phone users U1 and U2...
