Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic fabric reveals deeper mysteries about existence, change, and the very nature of ...

Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

In their study, Zhao and Smalyukh created a space–time crystal in the nematic phase of a liquid crystal. In this phase the crystal’s rod-like molecules align parallel to each other and also flow like ...

We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

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 ...

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square of the distance between them – the inverse square law. However, as Most ...

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 ...

A team at CU Boulder has made a curious state of matter in which particles move constantly—like a clock with hands and gears that spin forever, even without ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe ...

The visible patterns produced by the time crystals could be used for data storage and anti-counterfeiting designs.
