Gravity-bending find leads to Kepler meeting Einstein

(Phys.org) —NASA's Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon—a result of Einstein's theory ...

Shape from sound: New methods to probe the universe

(Phys.org) —As the universe expands, it is continually subjected to energy shifts, or "quantum fluctuations," that send out little pulses of "sound" into the fabric of spacetime. In fact, the universe is thought to have ...

Long-tailed tits help each other out

Long-tailed tits which lose their eggs or young may help to feed neighbours' chicks, researchers have found. But the degree to which they'll co-operate varies from year to year.

Gravitational telescope creates space invader mirage

(Phys.org)—The NASA/ESA Hubble Space Telescope is one of the most powerful available to astronomers, but sometimes it too needs a helping hand. This comes in the form of Einstein's general theory of relativity, which makes ...

Researchers explore quantum entanglement

Albert Einstein called quantum entanglement—two particles in different locations, even on other sides of the universe, influencing each other—"spooky action at a distance."

Physics researchers join effort to finally complete quantum theory

An assistant professor of physics at Indiana University-Purdue University Indianapolis (IUPUI) will be among a team of international researchers looking to advance the theory of quantum mechanics, a notion challenged by Albert ...
