Researchers have worked out how to make matter from pure light and are drawing up plans to demonstrate the feat within the next 12 months.



In a neat demonstration of E=mc2, physicists believe they can create electrons and positrons from colliding photons.

"We have shown in principle how you can make matter from light," said Steven Rose at Imperial. "If you do this experiment, you will be taking light and turning it into matter."

The scientists are not on the verge of a machine that can create everyday objects from a sudden blast of laser energy. The kind of matter they aim to make comes in the form of subatomic particles...
