Re: Teleporting rocket fuel as a Bose-Einstein condensate

Maybe I will only get a good explanation about why not... but what role could Entanglement play in this enterprise? I have read that entangled particles are the only confirmed instance of FTL transfer of information. When an entangled pair is shot in any two directions, the reading of spin on one always determines the spin on the other. If one is shot through a gizmo that would guarantee its spin, then you would be (in that same instant) spinning the other in the opposite direction. This may all be a bit simplified, but that is essentially how I remember it.

Taking Pyro's idea of quantum effects on a macroscopic thing, what if the transmitter and the receiver were in fact entangled at a quantum level? No matter how far apart they got, they would be the physics equivalent of the Corsican Brothers; one feeling the other's pain. At one device you feed information in, and simultaneously the same information is emitted at the other device. Could macroscopic entangled gizmos allow the conduction/transfer of more than just information? Could you send electrons through such a device? Could you send photons through such a device? Could you send atoms through such a device?

I always assumed that this is how interstellar communications would be made reasonable. Why not take it the next step?

A Fine-Tooth Comb To Measure The Accelerating Universe
imageAstronomical instruments needed to answer crucial questions, such as the search for Earth-like planets or the way the Universe expands, have come a step closer with the first demonstration at the telescope of a new calibration system for precise spectrographs. The method uses a Nobel Prize-winning technology called a 'laser frequency comb', and is published in this week's issue of Science.

Fermilab physicists discover "doubly strange" particle
imagePhysicists of the DZero experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b (Ωb). The particle contains two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and weighs about six times the proton mass.
