Scientists claim to have created a form of aluminum that's nearly transparent to extreme ultraviolet radiation and which is a new state of matter.
It's an idea straight out of science fiction, featured in the movie "Star Trek IV."
The work is detailed in the journal Nature Physics.
The normal states of matter are solid, liquid and gas, and a fourth state, called plasma, is a superheated gas considered more exotic. Other experiments have created strange states of matter for brief periods. This one, too, existed only briefly.
To create the new, even more exotic stuff, a short pulse from a laser "knocked out" a core electron from every aluminum atom in a sample without disrupting the metal's crystalline structure, the researchers explain.
''What we have created is a completely new state of matter nobody has seen before," said professor Justin Wark of Oxford University's Department of Physics.
"Transparent aluminum is just the start," Wark said. "The physical properties of the matter we are creating are relevant to the conditions inside large planets, and we also hope that by studying it we can gain a greater understanding of what is going on during the creation of 'miniature stars' created by high-power laser implosions, which may one day allow the power of nuclear fusion to be harnessed here on Earth."
Fusion is a dream of scientists who would create cheap and plentiful power by fusing atoms together, as opposed to nuclear fission that generates electricity today...
