Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

A recent study published in Nuclear Physics B examines how hidden dimensions might influence the physical reality that we ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and feasting on its stellar material. The observation is ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

Spacetime might seem smooth, but it could, at very short length scales, be quantized. Energetic neutrinos from gamma-ray bursts could provide a useful means to investigate further, and probe the ...
