So, Anti-Matter Blows Everything Up?

Actually, nope. Not always.

Enter the Majorana fermion, which has a neutral charge. It's matter. And its antimatter. In 1930s Ettore Majorana suggested it was possible.

Now they seem to have found it. Or more accurately made it. It requires superconductors and magnetism and...well, I'll let you read it here.


Here's the important thing about the Majorana fermion now we've found it. It's actually...quite, quite stable. Which means that it might be useful for quantum computing (because it's already both a 0 and a 1, as it were. Or maybe a -1 and a 1). It also doesn't interact much...dark matter, anyone?

But one intriguing bluesky possibility.

If Majorana fermions are stable, then they can be stored.

If they can then later be destabilized then we have a way to store antimatter. And that could be really useful (and scary).

We'll see. They haven't managed to interact with them yet beyond observation and maybe we can't. But think about it...
