Title text: And I can't believe some places still use fax machines. The electrical signals waste so much time going AROUND the Earth when neutrino beams can go straight through
Now I have to Google to see if neutrinos can be used to send signals for the internet. That would give me a nice advantage on Dota.
Edit fixed a typo.
You laugh, but for some people this is a real issue. High Velocity traders have to compete at 100 microsecond scales and data centers can charge differently according to how long the wires are to the market floor.
Impulses in electrical wire travel at 0.58c (CAT3) to 0.99c (open ladder) depending on how the conductors are laid out. Light impulses in optical fiber
travel at c/(avg index of refraction), which can be quite a bit less than c.
A few years ago commodity arbitragers constructed a microwave relay line between NYC and Chicago to gain a speed advantage - EM radiation
through air is a lot faster than fiber or wires.
They'd use neutrinos if they could - it would allow them to avoid relay latency, and be a shorter path.
