According to Grigorian, TimeCapsuleLLM's most intriguing recent output emerged from a simple test. When he prompted it with ...

According to Zych, this trippy thought experiment (and the math that backs it up) has the potential to directly inform the development of tomorrow’s quantum computers.

Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.

The Seattle scientist who wants to test a controversial prediction from quantum theory that says light particles can go backward in time is, himself, running out of time.

Time travel, once a ridiculous conceit, became a logical possibility when Einstein started bending time like taffy. Einstein showed that, as an object increases its speed, time slows down for it.

In his new book about time travel, astrophysicist Richard Gott has plenty of science to explain, but first he makes sure that his readers are up to speed on science fiction. The first chapter of "Time ...

This time around, it’s 20 years later, the ice has melted, and you’re fighting in jungle settings instead of the snow. And the game focuses on a bunch of characters instead of just one.

Backwards time travel would create pairs of objects that would annihilate each other, according to an interpretation of Einstein's theory of special relativity.
