Scientists really don't understand time... but they do have some theories about what it might (and might not) be.

Dubbing these “closed timelike geodesics” (CTGs), Ralph and Sajeendran explain in the paper: “Such a CTG would be ideal for ...

As scientists get closer to putting humans on Mars, the need to understand why clocks tick faster on the red planet is more ...

Scientists discover time rondeau crystal, a new phase of matter showing unique time-based order, distinct from time crystals.

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Breakthrough from Princeton team reveals exotic quantum state that coherently blends many-body correlation and quantum ...

Since 1991, UChicago’s Kavli Institute for Cosmological Physics has connected students from Chicago Public Schools with world ...
