If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all know that don't we? It's actually not true — and an attempt at a massive ...

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 ...

"General relativity is likely incomplete for describing the very first moments of the universe, when quantum effects should also matter." When you purchase through links on our site, we may earn an ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy, a measure of disorder. The theory, ...

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 ...

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 ...
