A scientist proposes a new law of physics suggesting the universe may be a digital simulation, linking physics, biology, and information systems as evidence.

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

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 ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

A team of researchers from King’s College and Imperial College London have proposed a new way to calculate entropy production in active matter systems Bacteria use chemical energy, usually from ATP or ...

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 ...
