Scientists may have figured out how to convert light into matter

Vox writes Scientists may have figured out how to convert light into matter

"Eighty years ago, physicists Gregory Breit and John Wheeler calculated that if you smashed pure photons of light together, you could theoretically convert them into tangible matter — but said that actually producing this process would be so difficult that it'd be 'hopeless to try to observe… in laboratory experiments'.

In a new article in the journal Nature Photonics, scientists at Imperial College London led by Oliver Pike propose a practical way of accomplishing this that would use lasers, a slab of gold, and an empty can."
