If anyone does it, it will be financial firms putting them under stock exchanges to get milliseconds of advantage over anyone following the curvature of the earth.

This implies financial feasibility. It still takes a super collider on one end and a detection tank on the other. But one day it might be feasible. I would think a military warning system would be implemented before a financial aid.

the shadows are so dark (or the secrecy so official?)....that for all we are able to know, they already done it.

We would see decisions being made that aren't physically possible with current technology. Also the number of people who would need to keep something like this a secret would be on par with that of a fake moon landing.

If their application of the technology were so secret that we couldn't tell it existed, then it wasn't worth whatever they paid.

Just need to have a satellite orbiting behind

Presumably it would be used in the case where a split-second decision is the difference between success and failure.

I would posit that, were a system like this feasible and already implemented by the military, we wouldn’t hear about this until the football has to be activated.

There is no single other decision as monumental and requiring of extremely precise timing. And it’s not a decision that is used very often or would be obvious if something “not physically possible” were done since it happens in secret. It’s pretty much the perfect usecase for such a technology.

This was studied decades ago. IIRC the effective bit rate, at least with the detector tech at that time, was insanely slow, like a few bytes per hour (or maybe even per day).

As long as the latency isn't also hours/a day, it could still be useful, even if just one byte, as you could communicate what that byte means out-of-band. So catastrophe-detection systems could use it as an example.

In this world? Eeeh, I doubt it.

From my understanding most exchanges put in artificial limits now to ensure anyone with mega bucks for infrastructure are equal

This is an awesome update. It was only in 2018 that a high energy neutrino was detected by the IceCube Neutrino Observatory (funny name lol) that was traced back to its source, a blazar. This was a active galaxy with a supermassive black hole at its center. That was the first time ever that scientists had identified the source of a high energy neutrino, and now scientists generated a whole new avenue of research in a…

> IceCube Neutrino Observatory (funny name lol)

It's also an incredibly descriptive and literal name - the observatory is a cubic kilometer of photosensitive detectors frozen in ice at the south pole. When a neutrino interacts with the ice, it produces cherenkov radiation, which can be detected and sent up the chain to a server to classify what was actually detected.

To be honest, I've read the first and second books and not entirely sure what you mean.

There's a scene at the end of the second book where the aliens offer to build a neutrino communication device for humans but the humans opt for one that uses gravity waves instead. It's a very brief reference, I don't know why the parent would have brought it up.
