“What Mark has done is put his finger on a key ingredient of how space-time is emerging: entanglement,” says Gary Horowitz, who studies quantum gravity at the University of California Santa Barbara. Horowitz says this idea has changed how people think about quantum gravity, though it hasn’t yet been universally accepted. “You don’t come across this idea by following other ideas. It requires a strange insight,” Horowitz adds. “He is one of the stars of the younger generation.”

Researchers have separated the nuclear spin states of water. In para water, the spins (depicted as arrows) of water’s two hydrogen nuclei cancel out. They add up in ortho water. The scientists produced an ultracold, supersonic beam of water molecules — a mixture of para and ortho water — and sent it through an electric deflector (blue device on the left). The deflector acts as a prism for nuclear spin states, separating para and ortho water molecules in space (right). (Credit: Daniel A. Horke, CFEL/DESY)

In this Sunday Sept. 7, 2014, publicly distributed handout photo provided by the Nicaraguan Army shows an impact crater made by a small meteorite in a wooded area near Managua’s international airport and an air force base. Nicaraguan government spokeswoman Rosario Murillo said Sunday that a loud boom heard overnight by residents of the capital was a “relatively small” meteorite that “appears to have come off an asteroid that was passing close to Earth.” (Credit: Nicaraguan Army/AP)

Finding clouds of water floating in the atmosphere of an alien world is a significant find. Now, astronomers have reported preliminary findings that water clouds have been detected in the atmosphere of a brown dwarf, a mere 7.3 light-years from Earth. (Credit: NASA, JPL-Caltech, O’neil)

NASA mechanical engineer, Brian Trease, worked with Brigham Young University doctoral student Shannon Zirbel, and collaborated with origami expert Robert Lang, who has long been active in promoting it in science, and BYU professor Larry Howel, to combine different traditional folds for an 82-foot solar array that whirls down to 8.9 feet.

“If we find a noise we can’t get rid of, we might be detecting something fundamental about nature – a noise that is intrinsic to space-time,” said Physicist Aaron Choi, the holometer project’s lead scientist. (Credit: NASA, ESA)

In this picture, which combines views from Hubble and the Keck-II telescope on Hawaii (using adaptive optics), you can see a foreground galaxy that is acting as the gravitational lens. The galaxy resembles how our home galaxy, the Milky Way, would appear if seen edge-on. But around this galaxy there is an almost complete ring — the smeared out image of a star-forming galaxy merger far beyond. (Credit: NASA, ESA)

With a circumference of 52km, the “Higgs Factory” would be almost twice the size of Europe’s equivalent, and significantly more powerful. The Chinese said it is due to be completed by 2028. Image above is the Large Hadron Collider. (Credit: Getty)

“It’s the most distant object for which the spin has been directly measured. The universe is about 13.7 billion years old, so this is going significantly back towards when the epoch of furious galaxy formation was happening,” says, Astrophysicist, Mark Reynolds.

Map showing Ceres and Vesta as they approach each other closely this coming week. Both asteroids are near the easy-to-find star Zeta in Virgo not far from bright Mars. Although the asteroids appear very close together in the sky, they’re really about 51 million miles apart with Vesta in the foreground. (Credit: Chris Marriott’s SkyMap)
By filtering light from the sun, CQT researchers have made a strong detection of a quantum effect known as ‘photon bunching’ in its light. This is a hallmark of the sun radiating like a black body. (Credit: NASA/SDO)

Mechanical oscillators translate an applied force into measurable mechanical motion. The Standard Quantum Limit is imposed by the Heisenberg uncertainty principle, in which the measurement itself perturbs the motion of the oscillator, a phenomenon known as “quantum back-action.” (Credit: Kevin Gutowski)
