How many states of matter are there??
By using lasers focusing on atoms of Aluminum scientists have made the atoms of the metal transparent. While we won't be at the helm of invisible starships any time soon, the research seems to open avenues that may lead us to better energy sources. And while we have a "we know it all" mentality sometimes concerning scientific discovery, this is just one more story that says "No, we don't know it all". Perhaps we are just at the cusp of a new practical scientific revelation.
"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."
