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

Physicists have recently made a groundbreaking discovery in the realm of quantum materials with the identification of a ...

A glittering hunk of crystal gets its iridescence from a highly regular atomic structure. Frank Wilczek, the 2012 Nobel ...

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

Scientists at TU Wien have uncovered that quantum correlations can stabilize time crystals—structures that oscillate in time ...

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 ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Scientists in Wales have built the world’s most sensitive table-top interferometer, which is a miniature, ultra-precise ...

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.

Only here, the rhythm unfolds not in space but across the very flow of time. The discovery of two new continuous time crystals could reshape how you think about time in quantum physics. These phases ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

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 ...
