Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

Should the universe “choose” braneworld, it could mean that your senses (which perceive fewer dimensions) are keeping you ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Andromeda sounds far away because 2.5 million light-years sounds far away. It lands with authority. It feels exact. It gives you the comfort of a labeled universe, one where galaxies, stars and ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Though spacecraft with artificial gravity are still a distant dream, we had proof of concept way back in September 1966.

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...
