Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter ...

Physicists propose that tangled cosmic “knots” formed after the Big Bang may explain why our universe is made of matter, not ...

This giant greedy atom can help scientists probe the reaches of ultracold atom physics. The space between an atom's nucleus and electron is usually barren. But, when an electron's orbit sits ...

Optical microscopes can help us see the microscopic world, but to use them to examine individual atoms is like measuring an ant with a measuring tape. An atom is way too smaller as compared to the ...

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the ...

Quantum entanglement is a phenomenon that’s as bizarre as it is fragile. Entangled particles are thought to lose this inexplicable link when exposed to outside factors. But now, physicists have ...

This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

The Nobel Prize in physics has been awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for their work looking at electrons in atoms in split-second moments. Hans Ellegren, the ...
