Could reality be made of more dimensions than those we perceive? The question has consumed some of the most brilliant physics minds for over a century, from unifying space and time into spacetime by ...

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 ...

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 ...

Extra dimensions: is evidence for string theory lurking in this rubidium BEC? Evidence for the extra space-like dimensions predicted by string theory could be found within Bose–Einstein condensates ...

Our universe may be hiding extra dimensions just beyond the reach of current experiments — and they could be the key to unlocking two of the most stubborn mysteries in physics. A new theoretical study ...

Physicists have long suspected that beyond the 3+1 dimensions that we are familiar with, there might exist additional space or time dimensions. But in an article published this September, a group of ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. Meanwhile, physicists are also trying to figure out how the ...

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 ...

Researchers attempting to solve the problem of dark matter have proposed a particle that can travel to an unseen fifth dimension. The work is entirely hypothetical, as it attempts to explain a type of ...
