A new study by researchers from the University of Barcelona and the University of Padua challenges one of the core ideas of modern cosmology: that the Universe began with a rapid expansion called ...

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 ...

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 ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

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.

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 ...

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...
