> and that is an upper bound

I've often wondered if for HFT or similar it might be worth pointing a particle accelerator at the floor and going for direct-line transit times. I'm fairly sure that this is theoretically possible, but no idea if the engineering challenge is beyond reach for use as a communication link.

If your signal is "transparent" enough go through so much rock and iron without being absorbed (like neutrinos), you'll have a hard time capturing it on the receiver side.

Well, OPERA was 700ish km, but had Cern at one end. If one has this as the sole goal and wanted to do it real-time over 12,000km is it "engineering-possible" vs "theoretically-possible" ? My guess is that it depends how much money stands to be made ;)

Basically just aim you accelerator at any neutron detector.

Problem is you'd drop more packets than IP over pigeons.

I think you're confusing neutrons and neutrinos. Firing neutrons at the floor will definitely give you a very radioactive floor.

Does carrier pigeons have that high packet loss?
