Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible field, but from the hidden geometry of space itself. Instead of treating extra ...

From high school mathematics to the renormalization group.The 5-volume series "The Complete Guide to Dimensional Analysis" is ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Time is the strange dimension: Unlike its spatial siblings, it is a one-way street as the clock only ever ticks forward and never backward. Scientists have long been aware of time's quirks, with the ...

Physicists aren’t known for playing fast and loose with the rules of reality. But when it comes to the concept of space, some take a remarkably permissive attitude. For most of us, it would seem there ...
