A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden ...

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 ...

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 ...

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 ...

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 ...

In a hypertorus model of the Universe, motion in a straight line will return you to your original location, even in an uncurved (flat) spacetime. The Universe could also be closed and positively ...

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 ...

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 ...

Does our universe exist in more than just three dimensions? Probably not on large scales, according to new research published July 23 in the Journal of Cosmology and Astroparticle Physics. The study ...

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 ...

Although we now think of the universe as three bulky, nearly-flat dimensions, we might soon discover that the fabric of space-time consists of many more dimensions than we ever dreamed. Extra ...
