Extra dimensions promise to solve many of current particle theory's nagging problems. They can explain the abundance of matter over antimatter, the surprisingly large number of elementary particles, ...

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 ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

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 ...

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 ...

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.

Last year, three physicists shared the Nobel Prize for their detection of gravitational waves produced by colliding black holes. Just two weeks after the prize was announced, physicists from the same ...

Most people are perfectly content with three dimensions to carry out daily tasks -- or four if they take time into account. String theorists, on the other hand, think that many more dimensions are ...

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 ...

MAKING a black hole let go of anything is a tall order. But their grip may slowly weaken if the universe has extra dimensions, something that pulsars could help us to test. String theory, which ...

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 ...
