For the second time in a week, a long-standing conjecture has been disproved by artificial intelligence, highlighting the ...

The universe’s expansion makes cosmic distance far less intuitive than simply measuring how long light has traveled.

Quantum technologies, which leverage the principles of quantum mechanics, have been found to outperform their classical ...

One of the most important ideas in physics is also one of the most misunderstood: entropy. It describes how energy naturally spreads out over time and helps explain why time appears to move in only ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

To some, METR’s “time horizon plot” indicates that AI utopia—or apocalypse—is close at hand. The truth is more complicated. MIT Technology Review Explains: Let our writers untangle the complex, messy ...
