This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Classically, the second law of thermodynamics implies that our knowledge about a system always decreases. A more flattering interpretation connects entropy with the uncertainty inherent to quantum ...

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 ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

A semiconductor device generates unforgeable watermarks from chaotic electron behavior, embedding invisible markers in images ...

Time-dependent driving has become a powerful tool for creating novel nonequilibrium phases such as discrete time crystals and ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Invariance. Constancy. Immutability. As we exist in the here and now, as we travel through space and time, as our lives get linked with one another, and as our states get entangled, the fundamental ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

The reason for this shift is simple: data gravity. The core holds the most complete, consistent and authoritative dataset available to the institution. Moving AI decisioning closer to this data ...
