In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

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 ...

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible field, but from the hidden geometry of space itself. Instead of treating extra ...

Physicists have spent decades treating mass as something particles simply possess, a built-in feature explained by the Higgs field but not fully illuminated by it. A new wave of research is now ...

The discovery of gravitational waves was announced in February 2016. Scientists used the Laser Interferometer Gravitational-wave Observatory (LIGO) detectors to find fluctuations in spacetime created ...

While last year’s discovery of gravitational waves from colliding neutron stars was Earth-shaking, it won’t add extra dimensions to our understanding of the universe—not literal ones, at least. The ...

June 28 (UPI) --Many theoretical frameworks used to explain quantum gravity and other cosmological phenomena, including string theory, require extra dimensions. Some use spacetime as a single extra ...

PBS Space Time is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart TV, and ...

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 ...

Only 2 years ago, the idea of extra dimensions inhabited a nebulous region somewhere between physics and science fiction. Many physicists had already begun to see the up-and-coming string theory as ...

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 ...
