At best you could gain a 24.5ms advantage (through the earth to other side @ 12,800km versus around it at pi*6,400km).Actually quite significant in HFT terms.

At best you could gain a 24.5ms advantage (through the earth to other side @ 12,800km versus around it at pi*6,400km).Actually quite significant in HFT terms. But: sady this is completely impossible. The weak force is not called the weak force for no reason. Neutrinos hardly interact with matter at all - that's why they can stream through 12,800 km of solid iron almost unimpeded. You would need a detector the size of the solar system in order to collect any meaningful data volume in real-time.

> You would need a detector the size of the solar system in order to collect any meaningful data volume in real-time. That's absolutely untrue. Why would you need to detect all neutrinos? Even if you were capable of detecting only a quadrillionth of all neutrinos sent your way, I could send 10^20 neutrinos per second your way. Although this project would be extremely expensive, it's absolutely possible with today's technology.

Assuming the radius of the earth is 6378.1 Km (it varies), the distance traveled over the circumference of half the earth will be 20037.375179 Km, compared to 12756.2 Km traveling straight through the earth. The difference is 7280.60115 Km. So the best possible case is a time saving of 7280601.15 m / 299792458 m/s = 24.285 mS (what parent said). Expanding on that a little: Using more realistic values, the distance between New York City and London is 5567 Km, while the path through the earth is 5392 Km (see http://imgur.com/Th6jW http://imgur.com/Th6jW). So this would save 175000 m / 299792458 m/s = 0.583 mS On the other hand, Spain and New Zealand are pretty much directly opposite (http://www.freemaptools.com/tunnel-to-other-side-of-the-earth.htm http://www.freemaptools.com/tunnel-to-other-side-of-the-eart...) each other, and Europe to Japan is pretty close to being on directly opposite sides of the earth. So London to New York might be cost effective at $25 million, assuming the same $300M/6mS (http://www.telegraph.co.uk/technology/news/8753784/The-300m-cable-that-will-save-traders-milliseconds.html http://www.telegraph.co.uk/technology/news/8753784/The-300m-...) rate, while best case (Spain to New Zealand) might be worth $1.2 billion.
