Mastering Light

thyristor writes "'Researchers at MIT document the ultimate control over light: a way to shift the frequency of light beams to any desired colour, with near 100 per cent efficiency. This technology could revolutionise a range of fields, from turning heat into light, or even into prized terahertz rays - which hold great promise for medical imaging. It could also make it possible to focus a wide range of frequencies into a narrow band, make devices such as light bulbs and solar cells more efficient, and help to keep optical telecommunications networks moving.' These are probably the most exciting results in photonics in the last decade."

      Especially since lightsabers that cut with electromagnetic radiations would just pass right through each other, right?

      I'd be like fighting with a flashlight. Although, it would promote a certain degree of finesse in swordsmanship; if you couldn't parry, would you just rush up to someone, the way medieval enthusiasts do when they know they can't get their feet chopped off? It would take some serious finesse to win a fight like that...or a longer lightsaber :/.

    I disagree with "Star Trek has been completed!"

    Star Trek will NOT be complete until we have discovered how the Klingons and Romulans make their CLOAKING DEVICES. And while we're at it, I wish Zephram Cochran would hurry up and be born so he can invent the Warp Drive. You know, I thought we almost had the Warp Drive with Asymetical Capacitors, but others here on Slashdot have pointed out that they don't work in a vacuum. One more thing, we need Transporters to beam down to other planets from orbit. We're a long way from Star Trek.
