Data transmission using neutrinos
Harvard University physicist Alexander Wissner-Gross, in an interview with Wired , suggested that in 20-30 years the world's largest financial companies will start using charged particle accelerators and neutrino detectors to transmit data directly through the Earth. Although the speed of a neutrino is no more than the speed of light, but by shortening the route it will be possible to reduce the latency by several tens of milliseconds.
Experiments on the transmission of data using neutrinos have already been. Just this spring, scientists transmitted information from the accelerator to Fermilab to a neutrino detector located a kilometer away. True, the data transfer rate during the experiment was only 0.1 bits per second. But scientists are confident that using correct modulation can increase throughput by one to two orders of magnitude.
Since 52 world stock exchanges constitute a single world market that works round the clock, prices ultimately tend to the same level. The competitive advantage in the market is received by the trading office, which receives data from overseas a few milliseconds faster than competitors. Therefore, renting a strip on a transatlantic cable with a delay of 59 milliseconds is 50 times more expensive than the same strip on another cable with a delay of 65 milliseconds. Accordingly, laying a new cable along a shorter route becomes economically viable.
In this situation, the speed of light becomes a bottleneck for high-speed trading . The time it takes for the signal to travel along the circumference of the earth’s surface between two of the most distant points on the globe is 67 milliseconds.

According to the Tabb Group agency, in 2010, global financial companies spent $ 2.2 billion on trading infrastructure (servers, communication channels) —on accelerators and detectors should be enough.
