One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant ...

A puzzle with only three moves may sound simple. In quantum physics, it can still break classical logic. That is the heart of ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

Might the mere fact of creating a time machine ensure its own elimination from history? That’s the disquieting suggestion of a new theoretical framework by Andrew Jackson, a research associate at the ...

(via Sabine Hossenfelder) In today’s video, I have a brief rundown of my 10 favorite physics paradoxes and big problems. If you have trouble sleeping at night, this will give you something to think ...

Breaking the time asymmetry remains a fundamental yet tantalizing scientific challenge. At the macroscopic level the quest has so far turned out to be fruitless, but on the other hand in the subatomic ...

Black holes have long puzzled scientists, especially because of a problem known as the black hole information paradox. Now, a ...
