A human tightrope walker is able to walk the rope only in one dimension, forward or backward. But an ant can access an ...

If we find that gravity starts acting weird at the scale of a micron, it could trigger a process of discovery that could ...

Of the four fundamental forces of nature, gravity is the most peculiar. It’s the most overreaching of the four forces, binding together structures hundreds of millions of light-years in diameter. Over ...

Has Gravity Disappeared into Another Dimension? — One of the Universe's Greatest Mysteries Hidden Within the Four ForcesWhat ...

Scientists know how gravity works at big distances -- the inter-planetary or inter-stellar range -- but does it work the same way at the inter-atomic range? A variety of tabletop experiments are ...

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 ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

In the effort to unify the gravitational theory of general relativity with the quantum theory of the very small theoretical physicists explore a lot of wild ideas. One of these is the idea of higher ...

FORGET Flatland, the two-dimensional world imagined in the 1884 novella by Edwin Abbott. On tiny scales, 3D space may give way to mere lines. So say researchers working on theories of quantum gravity, ...
