Astronomers have identified a tightly bound pair of stars that are spiraling toward a catastrophic merger, turning a distant ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

Sharper views of black holes are turning what once looked like a fuzzy cosmic icon into a precision tool for testing gravity ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Fr. Gabriele Gionti, S.J., and Fr. Matteo Galaverni continue to produce new mathematical insights into Albert Einstein’s ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

Leiden, a city whose university is often called the Oxford of the Netherlands, features museums, gardens, murals and plenty of ways to stretch your mind. Over the centuries, Leiden, a short train ride ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?
