The principle of relativity, as initially described by Galileo, posits that the laws of physics remain consistent regardless of an observer's relative motion. Einstein's special relativity ...

IT is with great diffidence that I enter the relativity controversy, since I know little or nothing of the subject. Ignorance, however, is seldom a bar to the expression of opinions. I understand that ...

(via Sabine Hossenfelder) The Andromeda Paradox, originally from Roger Penrose, is a brain-melting thought experiment that brings up the question of whether the future is still open or already fixed ...

We break down Einstein's famous twin paradox to illustrate time dilation in special relativity. Discover how acceleration, not just velocity, causes a difference in the aging of the twins and why the ...

THERE is, as Mr. Browne points out, a lapsus calami in my quotation. The supposed velocity of the cannon-ball is, not a twenty-thousandth of, but less by about a twenty-thousandth than, the velocity ...

Are black holes as simple as they appear, or is there more to their story? Theories that attempt to resolve the so-called black hole information paradox predict that black holes are much more ...
