Light Slowed Down To 127 mph
Makarand writes "Although slowing down a light beam is as simple as passing it through a window pane, slowing down light dramatically has always involved extremely low temperatures and rooms full of complex equipment. A new small device developed at the University of Rochester can now slow light down to 127 mph without using the room-filling mechanisms previously required. The new technique uses a laser beam to create a hole in the absorption spectrum of a common ruby at room temperatures that can allow a second laser beam, with a frequency slightly different than the first laser, to shine through that hole at a greatly reduced speed. This light slowing device might find applications in the telecommunications industry."
...work on getting us to light speed, rather than getting light to our speed?
Only in slashdot are posts of solidarity modded at -1 Redundant, while posts of antagonism are modded as -1 Flamebait.
Perhaps this could slow down fiber optic communications enough for a server to survive the /. effect.

or does it seem like these folks are sort of headed in the wrong direction with this stuff?
"Scotty, we need 38mph now, or we're all dead!"
Just doesn't have the same ring to it, you know?
We finally get the government to raise the speed limits on highways, so what do they do? Put a speed limit on light! Arrgh!
You just can't win.
The best part is, that we all know that when traveling faster than the speed of light in a vacuum, you can go backwards in time. So, by traveling slower than light in a vacuum, you move *forward* in time. As if this very moment I am traveling forward!
If you'd like to try this, get an airtight container and step inside. Remove all the air (such as with a match). Then start moving slowly. When you get out of the jar you sill notice that it is *later* then when you got in!

It consists of a vacuum tube surrounded by two helical rubys wrapped around in opposite directions. The momentum of the slow light traveling through the rubies warps spacetime in this device between the anode and the cathode of the tube. The electron beam is aimed so as to take a path through the warped spacetime region that will lead from cathode to the anode at a previous time.
Using this nifty device ( ONLY $19.95! on sale now at Best Buy! ) you can surf the web of the future easily! Just set the date you want to surf in your control panel and open a url.
How does it work? Your computer will save the http request on disc and send it out on the date you set in the control panel. On that date, it will recieve a reply and send the result back to your present self by encoding it as a cathode ray signal and sending it through the temporally warped region of the vacuum tube. The signal will travel from the cathode in the future to the anode of now.
Worried that your brand new outdated software will be incompatible with the future Internet? Will http be phased out? Not to worry!! You can download compatible software from the future using this device! To your computer the Mallet Temporal Network Card looks like any other ethernet card. It can even be used to surf the present by setting today's date in the control panel so you don't need to worry about finding slots for two network cards.
That's right, for just $19.95 you can download movies that haven't even been made yet! You can read tomorrow's obituaries and avoid a nasty car accident, you can play the Lottery and win - EVERY TIME! You can play the stock market without risk of losing your hard earned cash. Read books and download software that hasn't been written yet, and OWN THE COPYRIGHT! The possibilities are endless.
Mallet Temporal Network Card - How did you ever live without one?

This technology will finally enable us to create "gun-style" laser weapons that can be ducked, dodged, and deflected with light sabres.
