Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past ...

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 ...

In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...

Having more tools helps; having the right tools is better. Utilizing multiple dimensions may simplify difficult problems—not only in science fiction but also in physics—and tie together conflicting ...

Newton’s Law of Gravity just survived its biggest cosmic test. Scientists studied nearly 686,000 galaxies spread across 7 billion light-years. The result surprised even modern cosmologists. Gravity ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Big G, gravity, is the oldest fundamental constant in physics and the least clearly defined. One scientist has spent a decade attempting to crack the mystery.
