d=r(1/cos(s/(2r))-1)=3958(1/cos(6906/7916)-1)~=2198 mi; Yes, into the lower mantle with only 692 mi to go to the outer core. What I would love the internetz to explain is how to justify the h8 for HFT, yet the luv for Musk since he is the one in the driver's seat at the moment for this stuff with StarLink and the Boring company.
Satellite internet already exists; StarLink's defining feature is lower latency both by being in a lower orbit and inter-satellite links. It does benefit consumers by introducing another satellite internet competitor, but how many "normal" people want to rely on satellite internet or, if they do, care about a few extra 100s of ms of latency? (Inter)-National wireless companies have a tendency to consolidate and lobby out smaller companies and municipalities who have less incentive to build out fiber and landline companies, if any, have further justification to cut cords. StarLink is the now the leading solution for global low latency connections for HFT by being in a near vacuum in low orbit. The case for HFT benefiting non-professional trader Mrs. Mainstreet is that she no longer has to eat the larger spread offered by the big bank market maker every pay cycle when the 401K contribution hits with HFTraders providing liquidity. The opportunity for smaller traders to make the market is no longer there, but the odds that they would had a chance to begin with have been stacked against them for a long time with the cost of the fastest connection being marginal to now near insignificant.
And tell me how one would service any problems that arise either by tectonic movements or breaching an alien/breakaway civilization hollow earth chamber?
