You thought quantum mechanics was weird: check out entangled time

What if entanglement also occurs across time? Is there such a thing as temporal nonlocality?

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics. The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they have interacted.

Could an updated Feynman experiment finally lead to a Theory of Everything?

Measuring quantum gravity has proven extremely challenging, stymying some of the greatest minds in physics for generations.

For over a century, the two leading theories in physics have had irreconcilable differences, and scientists have scrambled to find ways to square them, to no avail. An experiment proposed in 1957 by American luminary Richard Feynman, is now getting a makeover, and the results could be significant.
