So, neutrinos don’t interact with 10^24 kg of rock, but can be easily picked up at the other end by a hypothetical $10 gizmo that does what the entire planet can’t; stop a neutrino.

Okay … that faster-than-light thing turns out to have been some sort of technical glitch. One can dream, though.

And the rationale is for arbitrage? And that arbitrage disappears as soon as the other guy gets access to the same technology?

I’ve got a bridge for sale…

If some college dropout can get $87 billion for automating 20-somethings’ address books, I’m sure my colleagues on Wall Street can drum up a few billion for this excellent notion.

Exactly how many neutrinos would you have to capture (above noise) to get a signal that would be profitable enough to pay for the project? You need to know that number because there’s also an itsy-bitsy detection problem– the linear dimension of a detector that would capture, say, half the neutrinos in a beam is on the order of light-years. Yes, light-years.

But nowadays they’re both vastly more complex.”

But the big difference is that QED was, in its domain, an extremely successful theory that matched experimental results to a high degree of accuracy. Other quantum field theories have been built on its foundation, to describe larger aspects of particle physics, but QED itself has never been superceded.

One could not make this claim about Black-Scholes.

But, there are a few issues…Unless only one-way communication is desired, two neutrino generators (particle accelerators) will be needed to send messages. Actually, this may be a small issue. There are desk-top accelerators currently in use.

The main problem is, based on current neutrino detection capability, the receivers (neutrino detectors) would; a) need to be very large, and b) need to be protected from the multiple other sources of neutrinos and neutrino generating particles. “a” makes receivers expensive, and “b” is why the current detectors are located deep under the ground, or under the ocean, or deep in the ice. These requirements limit the receiver location, and add to the cost of neutrino communication. Also, with the possibility of interference from other sources of neutrinos, comes the possibility of miscommunication.
