Ultra-Dense Deuterium Produced

Omomyid was among several readers writing in about the production of microscopic amounts of ultra-dense deuterium by scientists at the University of Gothenberg, in Sweden. A cubic centimeter of the stuff would weigh 287 lbs. (130 kg). UDD is 100,000 times more dense than water, and a million times more dense than deuterium ice, which is a common fuel in laser-ignited fusion projects. The researchers say that, if (big if) the material can be produced in large quantities, it would vastly improve the chances of starting a fusion reaction, as the atoms are much closer together. Such a D-D fusion reaction would be cleaner than one involving highly radioactive tritium. Many outlets have picked up the same press release that Science Daily printed pretty much verbatim (as is their wont); there doesn't seem to be much else about this on the Web. Here's the home page of one of the researchers. The press release gives no hint as to how the UDD was produced. Reader wisebabo asks: "I can easily imagine a material being compressed by some heavy duty diamond anvil to reach this density, the question is: what happens when you let the pressure off? Will it expand (explosively one would presume) back to its original volume?"

That's "dilithium"

[Actually, I do RTFA]

Woo-hoo, warp drive, here we come!

Oh, only "cold fusion here we come"? Fine, lets just solve our enrgy crisis then. *kicks rock, wishes for holodeck*

Heay douchebag, you can't get free redhead porn on the internet.

Hmm

Sounds like the university of gothenberg should just go walk nibbler.

No problem.

It's also good for practical jokes

Imaging putting a little bit of that in ones shoe...a great laugh!

Actually, it would probably be funnier to put it someone elses shoes.

But think how much heavier the Earth will be when they start making lots of this stuff. Won't that affect our solar orbit? Or the tide?

It's like how sponges can hold 25 times their weight in water. Imagine how high the water levels would be if they became extinct!

I don't know how people can sleep...

I don't think they could do much better than claim a major breakthrough in Hot Double-D Reactions.

It's so dense that a single pound of it weighs over 10,000 pounds!

You're right -- just think of what a boon this will be to the mining and drilling industries.

Because you know, that's all it's going to be good for. It's dense enough to fall through granite and limestone like they were tissue paper. I'm getting a figure of mechanical pressure that's about twice what hardened steel can take.

Fill a soda can with this stuff and watch it shoot down into the center of the Earth, with nothing you can do to stop it. If it's any consolation, after that it will probably fuse and explode.

I, for one, welcome our new swedish doomsday weapon.

I'm having fun imagining him trying to lift and lightly toss 35 thousand pounds of anything.
