| > 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. |

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 ;) https://en.wikipedia.org/wiki/OPERA_experiment | | |
