Doing Without Dark Energy

Three mathematicians have a different explanation for the accelerating expansion of the universe that does without theories of “dark energy.” Einstein’s original equations for General Relativity actually predict cosmic acceleration due to an “instability,” they argue in paper published recently in Proceedings of the Royal Society A.

New type of supercomputer could be based on ‘magic dust’ combination of light and matter

The researchers, from Cambridge, Southampton and Cardiff Universities in the UK and the Skolkovo Institute of Science and Technology in Russia, have used quantum particles known as polaritons – which are half light and half matter – to act as a type of ‘beacon’ showing the way to the simplest solution to complex problems. This entirely new design could form the basis of a new type of computer that can solve problems that are currently unsolvable, in diverse fields such as biology, finance or space travel.

“Spookiness” Confirmed by the First Loophole-free Quantum Test

FQXi catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality, but unlikely to be supported by conventional funding sources.
