Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

The most vivid implication of this situation is Heisenberg’s uncertainty principle, introduced in 1927, which says that there is no state an electron ... by black holes one billion light-years ...

In quantum physics, subatomic particles behave strangely—they can be in two places simultaneously, move through solid objects ...

Two NASA rocket missions are taking to the Alaskan skies in hopes of discovering why some auroras flicker, others pulsate, and still others are riddled with holes. Understanding these peculiar ...

Boron contains one less electron than carbon, allowing it to accept electrons. Boron essentially opens up a periodic electronic "hole" in the material that has the effect of increasing the ability ...

Advanced imaging techniques like X-ray diffraction and electron microscopy confirmed ... singularities are thought to exist only within black holes, concealed behind event horizons that prevent ...

How can the latest technology, such as solar cells, be improved? An international research team led by the University of ...

The researchers state that the discovery of this extremely high-energy neutrino is the first concrete proof that the universe produces neutrinos at these incredible energy levels.

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

They are in essence the eigenmodes of a material system that correspond to oscillations, at optical frequencies, of the electron liquid with respect to the crystal lattice. It can be shown that ...

"Black holes really do sit at the frontier of human understanding." Scientists have discovered that some supermassive black holes rotate much more rapidly than expected. The discovery came as the ...
