Spooks enlisted in hunt for gravity waves

09 August 2008


THE search for gravitational waves has a new recruit. These ripples in 
space-time, which are thought to
emanate from violent events such as the collision of black holes and the 
first moments of the universe's
existence, could be picked up using the spooky phenomenon of quantum 
entanglement. Machines based
on the principle might even outperform the enormous gravitational wave 
detectors now operating in the US.

Einstein's spooky action acts at 10,000 times the speed of light

13/08/2008


Now, by making measurements in two Swiss villages separated by 11 miles, 
Daniel Salart, a doctoral student
working with the team of Prof Nocolas Gisin at the University of Geneva, 
has run detailed measurements and
concluded that if this spooky action really exists, it must act faster 
than light.

The new work lays down a lower speed limit of 10,000 times the speed of 
light. Quantum weirdness still rules OK.

This study in the journal Nature suggests that a physical signalling 
mechanism that connects the villages is
deeply implausible, because of the well known limit of the speed of light.
