Photons from Nothing !

Check this out … and who says it couldn't all have come from nothing ? …

Researchers create light from 'almost nothing'

Quote:
A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible "sparks" from the nothingness of a vacuum.
… all courtesy of the Casmir effect in a quantum vacuum !!

Amazing stuff … great party trick !!

"Let there be light !!! …. "

Cheers
