We never measure time directly; instead, we use clocks to measure moments in time, meaning “time” is just a measurement of ...

Other scientists have investigated the idea of a hidden structure further. David Bohm, a 20th-century physicist, built a fully deterministic alternative to quantum mechanics, in which particles move ...

Quantum experiments keep stripping away our everyday intuitions, replacing them with a picture of reality in which cause, effect and even “facts” depend on how we look. New tests of entanglement, ...

The modern scientific world prides itself on precision, empirical rigour, and the pursuit of measurable truth. Yet, some of ...

As we go about our daily lives, we tend to assume that our perceptions—sights, sounds, textures, tastes—are an accurate portrayal of the real world. Sure, when we stop and think about it—or when we ...

Indian philosophical schools, such as Vedanta and Sankhya, propose that the world is not real, but rather an illusion (Maya) ...

Alyssa Ney is professor and chair of metaphysics at the Faculty of Philosophy, Philosophy of Science, and Religious Studies at Ludwig-Maximilians University Munich, Germany. This week, physicists are ...

A new theory suggests that time might not be a fundamental aspect of our universe but rather an illusion created by quantum entanglement. Quantum entanglement occurs when particles become ...

As Joe Howlett points out, "the Schrödinger equation remains physicists’ foremost window into the quantum realm. It tells scientists how that strange world works; that is, how quantum objects interact ...

Physicists have shown how time can effectively be reversed for some quantum systems, which would allow for new ways to ...
