Scientists propose seven-dimensional universe model where black holes leave tiny remnants that preserve information and could ...

For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only a sliver of reality. Extra dimensions, if they exist, would not just be a ...

Stephen Hawking's theory of black hole evaporation clashes with the laws of quantum mechanics. A new paper finds a way around ...

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special relativity that includes observers moving faster than light. This fresh perspective ...

In addition to the four dimensions we normally experience - height, length, depth, and time - physicists argue that there are ...

One of the weirdest theories in cosmology is the holographic principle, the idea that our universe is a three-dimensional image projected off a two-dimensional surface — the idea that, yes, we are ...

Scientists have created the largest and most detailed 3D map of the universe ever made, offering a fresh way to understand ...

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 ...
