Proposed Experiment to Convert Light into Matter in Simplest Way Known

Light to Matter Conversion: Given enough energy, two colliding photons (light particles) can produce a matter particle and antiparticle, such as the electron and positron shown here.

Experiments have shown how to convert matter into light, but reversing the process isn’t quite as simple. There’s a new theory to solve the puzzle.

Researchers have found direct evidence of Cosmic Inflation, a theory that suggests ripples in the fabric of spacetime produced an enormous hyper-expansion of space after the Big Bang.

Faster than the Speed of Light? NASA Looks at Warp Drive

The Latest from CERN: It’s a Higgs!

Real CMS proton-proton collision events show expected characteristic of Higgs boson decay. (Four high energy electrons shown in green lines and red towers.) Image by CERN.

CERN has concluded that the Higgs-like particle they found earlier is indeed a Higgs Boson particle: A conclusion with many implications.
