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

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

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 ...

For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...

It’s been two years since scientists discovered evidence of gravitational waves. Now, they’re figuring out what we can do with them. Recently, they found a huge, early contender: Using them to unveil ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain. Ordinary matter, the stuff we can see and touch, accounts for just ...

Physics education is a subject that is almost as big as physics itself, and in some ways it is even more complex. Although the laws of physics are the same in Belfast, Bologna and Berlin, the way in ...
