Oh happy day! Nature reports that a team of scientists at the University of California, Riverside have successfully created the formerly theoretical molecule known as Di-positronium. It can exist for only the tiniest fraction of a second, which is plenty long enough for one of its projected uses.
Get ready for it. It’s the gamma-ray annihilation laser.
The gamma-ray annihilation laser is a useful tool that falls into an important category, for me. That’s the category of “things I’d really like to have, but which I’d rather you didn’t”. Like the flying car.
Anyway loads of information about this, though – I’m happy to say – not enough that you can drop everything and cobble together a gamma-ray annihilation laser* of your own – are available at BBC News.
“The difference in the power available from a gamma-ray laser compared to a normal laser is the same as the difference between a nuclear explosion and a chemical explosion,” said Dr David Cassidy of the University of California, Riverside, and one of the authors of the paper.
*I just really like that name.
