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 ...

A new underground facility called DUNE, which will accelerate particles for 800 miles between Illinois and South Dakota, could reveal the hidden dimensions of the universe, new research suggests. When ...

While the existence of extra dimensions is a cool idea, it's currently not supported by any evidence ...

Our universe may be hiding extra dimensions just beyond the reach of current experiments — and they could be the key to unlocking two of the most stubborn mysteries in physics. A new theoretical study ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

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 ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

In 2013, François ENGLERT and Peter HIGGS won the Nobel Prize in Physics for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles ...

How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. We should expect to see not only phenomena ...
