Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very ...

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers. Strangely, although we feel as if we ...

Physicists have recently uncovered a groundbreaking material known as “time crystals,” which challenges our conventional understanding of time and space. This discovery, rooted in quantum physics, ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

The idea of time in physics is often associated with the second law of thermodynamics, which states that the entropy of an isolated system increases over time. Since the world keeps moving forward on ...

How we perceive and experience time is fundamental to our lives but we don’t fully understand what is a complex phenomenon. Sidney Perkowitz looks at how scientists and philosophers alike are seeking ...

Strangely, although we feel as if we sweep through time on the knife-edge between the fixed past and the open future, that edge—the present—appears nowhere in the existing laws of physics. In Albert ...
