Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It's a question that's difficult to answer, but physicist Melvin Vopson of the University ...

Scientists are closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force works in ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if you analyze the ashes of the fire, the smoke and the flames to re-create ...

If not in visible stars and galaxies, the most likely hiding place for the matter is in the dark space between galaxies.

What happens if you do a big jump? Your body goes up into the air. But then it comes back down again. The reason you don’t just keep going up, up, up is because the force of gravity pushes your body ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...
