Nobody took John F. Clauser's quantum experiments seriously. 50 years later, he's collecting a Nobel Prize.

By Jonas Enander published

John F. Clauser reflects on receiving the 2022 Nobel Prize in physics for the groundbreaking work he did 50 years ago.

The effect has been observed for the first time in a dense atomic cloud.

'Quantum time flip' makes light move simultaneously forward and backward in time

By Ben Turner published

The time-flipped photon can't be used to restage "Back to the Future," but it could help us figure out some of the universe's most mysterious phenomena.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

Something is wrong with Einstein's theory of gravity

By Kazuya Koyama, Levon Pogosian published

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.

What is the third law of thermodynamics?

By Jim Lucas last updated

Reference According to the third law of thermodynamics, the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 kelvin).

The Menlo Park lab of Thomas Edison, who invented the lightbulb, is shown here after its relocation to the Henry Ford Museum in Greenfield Village, Dearborn, Michigan. The arrow on the vacuum pump (center) marks the site of Edison's recreation of the lighting of the incandescent bulb on Oct. 21, 1929.

Who invented the lightbulb?

By Elizabeth Peterson, Callum McKelvie published

Reference Though Thomas Edison is credited as the man who invented the lightbulb, several inventors paved the way for him.

States of matter: Definition and phases of change

By Mary Bagley published

Reference The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.
