The Twin Paradox is one of the most fascinating and perplexing concepts in Special Relativity. It involves two twins: one stays on Earth while the other travels through space at near light speed. Upon ...

Fermilab physicist Don Lincoln explains a well-known thought experiment examining the consequences of special relativity. “Time waits for no man” goes the saying, and it appears to be true. Inexorably ...

(via Sabine Hossenfelder) Physicists have come up with a new experiment to test the quantum twin paradox using a pair of atoms in a superposition. It's an interesting idea because it could tell us ...

Subhash Kak, Delaune Distinguished Professor of Electrical and Computer Engineering at LSU, recently resolved the twin paradox, known as one of the most enduring puzzles of modern-day physics. Subhash ...

Fermilab’s Don Lincoln is back with yet another entertaining video, this time about what people get wrong about time dilation. In particular, he asks whether the famous “twin paradox” is actually ...

AS MAXIMS GO, Time is relative may not be quite as famous as Time is money. But the notion that time speeds up or slows down depending on how fast one object is traveling relative to another surely ...
