A pop up book about the LHC should also have a page showing massive piles of money being sucked into a vortex. #atlaspopupbook

So if CERN is Black Mesa, just who is Aperture Science? #cernhalflife

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

Needs more boxes and 50 gallon barrels. And headcrabs. #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

@dingus: Clearly CERN needs some instruction from your local Univ. They also need more dangling, sparking electrical wires. #cernhalflife

Wow. Dude, that's like way back when you had to actually DO SOMETHING to win a Nobel prize!

Good find!

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.

@jepzilla: Doesn't this break conservation of energy, assuming there is only kinetic energy? Do you know where an english copy of the paper is?
