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

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

This could be the way the world ends. First, a pair of cosmic protons smash together at unimaginable speeds. The tremendous energy of their crash would create a tiny, ephemeral black hole, so small ...

Our universe has three spatial dimensions – or rather, three that our human senses can actively perceive. Some theories suggest there could be many more dimensions that we're unaware of, mostly ...

It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those ...

The universe as we know it is made up of three spatial dimensions, right? The size and location of everything can be plotted out on a graph of X, Y and Z axes – at least, that's what our everyday ...

Extra dimensions sound like science fiction, but they could be part of the real world. Extra dimensions sound like science fiction, but they could be part of the real world. And if so, they might help ...
