The universe, where space-time becomes discrete

In quantum gravity, classical physics and quantum mechanics are at odds: scientists are still uncertain how to reconcile the quantum "granularity" of space-time at the Planck scale with the theory of special relativity. In ...

New method of finding planets scores its first discovery

(Phys.org) —Detecting alien worlds presents a significant challenge since they are small, faint, and close to their stars. The two most prolific techniques for finding exoplanets are radial velocity (looking for wobbling ...

A solar eclipse sheds light on physics

On 29 May 1919, a shadow dance took place over the Caribbean which was to make history: While the new moon covered the blazingly bright disk of the Sun, astronomers around Arthur Stanley Eddington measured the shift of stars ...

Physicists wary of junking light speed limit yet

(AP) -- Physicists on the team that measured particles traveling faster than light said Friday they were as surprised as their skeptics about the results, which appear to violate the laws of nature as we know them.

Light bursts out of a flying mirror

(Phys.org) —An international team of researchers succeeds in generating flashes of extreme ultraviolet radiation via the reflection from a mirror that moves close to the speed of light.
