Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion of the universe.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Albert Einstein's general theory of relativity describes gravity as the warping of space-time geometry by mass, a concept distinct from Isaac Newton's absolute space and time, and has been empirically ...

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.

The masses of fundamental particles such as the Z and W bosons could have arisen from the twisted geometry of hidden dimensions, a new theoretical paper has demonstrated. The work has outlined a way ...

Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance that accounts for more than 80% of the universe's mass could interact with itself. ...

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 ...

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...
