You gotta bore for that sweet latency win. A chord tunnel between San Francisco and Hong Kong would save 1300 miles (20% improvement right there), and if you drill it straight enough, you won't even need a cable.
- jodrellblank 6y agoAlameda enterprises excited by rumours of new chord tunnel Thursday, low latency burrito delivery futures up 5%.
- idlewords 6y agoWe have the technology!
- simoneau 6y agoAnd they are heated along the way!
- kstrauser 6y agoCurrently posting from Alameda. If you cause a local surge in demand that means I have to outbid a Manhattanite for a good burrito, I will cut someone.
- throw_away 6y agoBagelRail was dual use before the fiasco
- extropy 6y agoNeed to have lava shields for that.
- idlewords 6y agoThe photons go through fast enough that they won't get very hot.
- bmcahren 6y agoRemember: You want your photons crispy around the edges, not charred.
- leprechaun1066 6y agoI take my photons medium-rare.
- craftinator 6y agoNot to make light of these puns, but they aren't very coherent...
- kefabean 6y agoOn reflection I think we could all use a bit of light relief at the moment!
- uticus 6y agoMedium-rare with a light salad
- samstave 6y agoI only use recycled photons, so my light is green.
- LargoLasskhyfv 6y agoWho cares? Would be totally worth it because of unlimited geothermal energy!
- jeffbee 6y agoHeh baby steps maybe? The existing cables aren’t even short paths along great circles. The Oregon-Japan cable google owns is 12000 km along a 7500-km path.
- thomaslangston 6y agoMore feasible would be transmitting neutrinos or some other signal that would not be blocked by the Earth.
- jxcl 6y ago> More feasible If they don't interact with the thousands of miles of earth between the source and the destination, they probably also won't interact with the receiver! :p Imagine the retransmission rates! https://en.wikipedia.org/wiki/Neutrino_detector https://en.wikipedia.org/wiki/Neutrino_detector
- atonse 6y agoAnd you'd also have to ignore all the insane amounts of noise coming from regular neutrinos wizzing about in the universe.
- parineum 6y agoIf you've built a reliable detector, you've already built something that can intercept them. You just need to make a shroud around your detector and a tube facing your transmitter out of the same material.
- ISL 6y agoThere are ~65,000,000,000 neutrinos from the sun passing through each square centimeter of your hands every second as you read this. There are no materials on Earth that can reliably stop any given neutrino. For that, one needs densities greater than those generally found in stellar cores. Neutrino detectors work by maximizing dumb luck through being both very large and very, very clean (low radioactivity). The transmitter-detector systems work by sending oodles of very energetic neutrinos at a well-defined time and looking for a rare coincident flash in the detector.

- BelenusMordred 6y agoPlease don't give the HFT's ideas, they'll probably do it and cause a half dozen tsunamis in the process.

- hinkley 6y ago...and create a supervolcano.
- ISL 6y agoIf you don't like HFTs, this is an idea you'd probably like to give them. Nobody has ever drilled through the Mohorovicic. It is unclear whether or not it is possible to do so. The most-likely outcome is a few happy geologists/geophysicists and a number of very-sad HFT underwriters. https://en.wikipedia.org/wiki/Mohorovi%C4%8Di%C4%87_discontinuity https://en.wikipedia.org/wiki/Mohorovi%C4%8Di%C4%87_disconti...

- dekhn 6y agocouldn't you start experiments using the Alameda-Weekhauken tunnel?
- rorykoehler 6y agoHow deep would this bore tunnel be at the centre most point if it was perfectly straight? Would it go into the mantle?
- potiuper 6y agod=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.
- samstave 6y agoAnd tell me how one would service any problems that arise either by tectonic movements or breaching an alien/breakaway civilization hollow earth chamber?
- potiuper 6y agoRepair it like any other tunnel that requires maintenance?
- wmf 6y agoBecause HFT helps the rich AF get richer but Starlink benefits normal people?
- potiuper 6y agoSatellite 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.

- m463 6y ago> if you drill it straight enough, you won't even need a cable. Well, yes and no. I recall they wanted to pursue hollow cables in the early days of optical cabling, but it turned out solid fiber was the answer. (sorry, can't find a good reference) So FTTC (Fiber Through The Core) is what you want.
