A 24,000-atom experiment constructs an internal clock from entropy exchange, offering a laboratory test of how time might ...

When I follow stories about the universe, sometimes the words themselves take up residence in my head before I truly understand them. Replica wormholes, or quantum extremal surfaces, for example. I ...

The term entropy is used in information theory as a "measure of the uncertainty associated with a random variable" and refers to an axiom called the Shannon Entropy. The concept was introduced by ...

We finally understand how black holes get their entropy. Physicists have been struggling to figure this out since the early 1970s, when Stephen Hawking and Jacob Bekenstein calculated how much entropy ...

A remarkable yet mysterious property of black holes is that their entropy is proportional to the horizon area. This area law inspired the holographic principle, which was later realized concretely in ...
