I think your understanding of the damage an extinction-level meteor would cause might be a bit off. The whole issue with extinction-level meteors (or any event for that matter) is if you don't avoid it, there is pretty much nowhere on earth that you can be safe. It seems far easier to try and redirect the orbit of an asteroid than alter the orbit of the earth itself (which would be the only way to not be where the meteor is going to be.)

This is huge for arbitrage markets where you want to have a server close to more than one exchange (i.e. NYMEX/CME in New York and IPE in London.) Example is the spread between WTI and Brent crude is very actively traded. You can do this trade on legs (individual flat price trades on each side) or outright as a contract. Black boxes are scalping that all day long. A 6ms advantage means you can take advantage of market inefficiencies between the two exchanges before other people can, huge benefit. Heck there is even a WTI contract on IPE and one on the CME, that is a very scalpable market with the right setup.

the 'flash crash' had impact far beyond just the NYSE. Crude oil dropped $3/bbl in a very short period of time and rebounded. With commodities markets as leveraged as they are it would have been quite easy to rake in massive amounts of money if you knew the incident was coming

This has got to be the stupidest idea yet. If we assume 30 dollars one way as a reasonable fair, and it does not go into cost overruns, and it costs ZERO dollars to operate once it is built, it will take 156,000,000 trips to pay for itself. At 50 dollars one way, it is still 94 million trips. How many people make that commute? How long will it take to pay for itself? Of course, we know it WILL go into cost over runs, and it will cost a great deal of money to keep going, for maintenance, employees, power, etc. Can anyone explain to me how this will be economically feasible? Anyone? Arnold?

Let's not jump to conclusions here. These numbers are unrealistic. First of all, a reasonable fair of $30? It would cost $50+ in gas (not to mention depreciation) alone at 30mpg on the highway. Let's say $60 one way. That matches the cost of a flight and has a lot less hassle. The eurostar capacity is 15 trains per hour, 800 people per train which translates to 12,000 passengers, per hour, per direction giving 24,000 passengers per hour counting both ways. Say you run at 50% capacity on average, that is still $720k/hr at $60 per ticket, and you can easily have a first class cabin that has a higher cost. Say you spend 75% of that on operating costs, etc and you still need just 26,000 hours of operation to pay that 4.7bil. that is under 3 years of operating at 50% capacity. Even if this can pay itself off in 10 years it would be a great investment for the state to make. Now I know my numbers aren't perfect but the breakdown in the parent post is ridiculous
