I hope they have some big doors there that lock tight, to hold all the aliens in there.
But, the vortigons (sp?), can actually be useful and go into the medical industry. Since they revived Alyx after her enounter with the hunter. #cernhalflife
As a guy named Gordon -- and a Gordon who has worked at particle accelerators before, and is wearing a SLAC hoodie at this very moment, at that -- I completely agree with this assessment. #cernhalflife
@Jackhole: The halls in the basement of the local University's physics department are lined with big crates, usually marked with some indication that it had once shipped some sort of big honking laser. #cernhalflife
That's actually really, really interesting. Basically, the way a space vehicle works is you fling stuff out the back. The exhaust gains some momentum in one direction and you get an equal amount of momentum in the direction you want to go. Chemical rockets work by shooting large amounts of propellant (exhaust) out the back at low speeds. Electrical rockets work by shooting out a lot less propellant, at much higher speeds. The amount of momentum you gain for a given amount of propellant is known as specific impulse, and generally the bigger number the better. Increasing specific impulse can have a huge impact on the fuel requirements for a given mission, which is why electrical engines (with very high specific impulses) are so interesting.
But what Hilbert proposed is that you can actually get MORE momentum out of your propellant than you put in, if your exhaust speed is above half the speed of light. Now usually what relativity giveth, relativity taketh away. But assuming that there aren't any gotchas that make this useless in practical terms (big assumption), it could point the way toward engine designs which require an order of magnitude less fuel than even fancy shmancy electrical engines.

Are these teeth marks.
I thought it was chocolate.
It isn't!
Then why was it wrapped in foil?!
It was never wrapped in foil!
