"However, Einstein's theory of general relativity predicts the existence of time loops ... through a different route or by a ...

IN the course of reasoning on this subject with some of my more recalcitrant friends, I have come across a numerical example which I think makes the matter easier to follow than would any ...

Theoretical physicists have proposed a new solution to the Schrödinger's cat paradox, which may allow the theories of quantum ...

It illustrates and resolves several apparent paradoxes of special relativity including the twin paradox and train-and-tunnel paradox. Assuming a minimum of technical prerequisites the authors ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

Einstein came up with an example to show the effects of time dilation that he called the "twin paradox ... to Einstein's special theory of relativity, objects gain mass as they accelerate ...

General Relativity Quantum mechanics and general ... his attempt to unravel the mysteries of the black hole information paradox. According to standard quantum theory, information cannot be destroyed.

That prospect is called the black hole information paradox. It has occupied physicists for decades, not only because it highlights the profound disconnect between general relativity, Albert ...

The diagrams guide the reader, step-by-step, from the basics of relativity to advanced topics including the addition of velocities, Lorentz contraction, time dilation, the twin paradox, Doppler shift, ...

The Clock Paradox This celebrated consequence of the special theory of relativity is that two clocks that are moving with respect to each other run at different speeds. The effect rests on nothing ...
