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 ...

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 ...

Recent discoveries in the realm of physics have pointed to the possibility of time anomalies that challenge our current ...

Many scientists hold the belief that the paradoxes associated with time travel, which have perplexed thinkers for centuries, ...

Supermassive cosmic objects, such as black holes, are very difficult to study directly, but researchers can construct useful analogues in the laboratory using quantum effects. For example, researchers ...

Frank Wilczek has one of the most brilliant and original minds in theoretical physics, having come up with the idea of time ...

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 new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

What if, just before we reach the bottom, we find out that reductionism fails? Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the particle nature of dark matter." When NASA’s Nancy Grace Roman Space Telescope ...
