  • Commented on Canned Monkeys Don't Ship Well, the Remix Version
    Source regarding DNA damage being mostly indirect: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4071054/ Also has a good picture. So basically a dry tardigrade, in addition to all the repair it does when it gets re-hydrated, simply makes a smaller target and doesn't receive nearly as...

    > The problem with being exposed to 0.29Sv of ionising radiation over a thousand years of hibernation sleep is that there are no biological repair mechanisms at work while the tissues are frozen and dormant. That is also the problem...

    I think it's very far-fetched that the gut microbiome data would push out Earth-made relics. Which we could stuff in a shoebox on some metal mask ROM chips, if we wanted. Or microsd cards, but all flash would need to...

    > Point at anything from Assad to Trump to the Saud-du-jour and the best you can hope for is a UK-style devolution process via "armed negotiation". More likely you have the Russian example with a revolution or invasion every few...

    Let's say we have a steel ball bearing that weights 1 gram going at 2% of the speed of light. The volume of the ball bearing is 0.125 cubic centimeters, and the diameter of the bearing is 6mm. Cross section...

    Ohh and I know third post in the row and everything, but regarding shielding against dust particles... probably a relative non issue. Multiple layers of very thin plastic films, very far apart, in front of the ship. Can have them...

    Ohh and with regards to radiation discussion, apparently the annual dose from internal sources is 0.29 mSv (according to wikipedia), meaning that in 1000 years as a popsicle you'll get 0.29 Sv which isn't good to receive all at once...

    You'd definitely want computers for controlling all the valves and plumbing and life support systems and so on. re: diffusion, an absolute non issue even with modern chips, although for space you would likely be using old process chips (because...

    As far as social issues with the interstellar travel go... I feel that maintaining stability inside the ship, maintaining enough competence for on-board repairs (using stored spare parts), those are all very big issues if your end goal is to...

    I think the computer issue is over-rated. You need surprisingly little actual computing power for navigation, a common $4 microcontroller has more power than Apollo navigation computer. And the lifetime of actual silicon, when not thermally cycled, is essentially infinite....
  • Commented on Test Case
    Here's my prediction: Self driving cars will be put in a major use while at least as dangerous as an intoxicated human driver, probably more. All the speculation about the theoretical potential of better than human performance notwithstanding. Human drivers...
  • Commented on Why I barely read SF these days
    I think the spaceship dogfight is usually done far closer to naval-in-the-water battles, than even WW1 fighter planes... You can get kinematic action even with WW2 speeds, as all the aiming is done manually and planes have to be identified...
  • Commented on Unforeseen Consequences and that 1929 vibe
    Regarding the bitcoin power usage, basically what happens with bitcoins is that when the coins a miner produce by mining (+ transaction charges) are worth substantially more than the cost of electricity, that means it is profitable for each individual...
  • Commented on Report on Seat 14C
    Ohh, here's an idea: one or more of the pilots were Muslim, and they passed a bunch of "anti-terrorism" laws following the disappearance; there is now a vested interest in not believing the time travel story even if there was...
  • Commented on Report on Seat 14C
    It is a little bit too futurist IMHO that VHF communication would not be around... You can just have VHF communications and yet the plane getting shot down anyway. E.g. the pilot speaks English with Arabic sounding accent, the disappearance...
  • Commented on Some notes on the worst-case scenario
    > All it takes is a 0.1% asshole who's betting long on Monsanto and who decides to help things along by hiring a couple of shady military contractors to hit up a Brazilian agronomy lab Monsanto itself would have all...
  • Commented on And the Rabid Nazi Raccoons shall inherit the Earth
    > it takes rare-earth magnets You hit 90%+ mechanical to electrical efficiency in larger generators with or without rare earth magnets, with 2016 technology or with 1916 . That's all basically irrelevant compared to the difference between those sailcloth windmill...
  • Commented on Just plain icky
    Well, a much simpler explanation is that more conservative attitudes have worse public healthcare and consequently more parasites. Any you can't measure healthcare quality without circularly measuring parasites. Other thing is that a lot of parasites come from consuming poorly...
  • Commented on We'll all go together when we go
    Ohh and keep in mind that a nuclear war is unlikely to be followed by kumbaya and everyone getting along, but instead would include literally everything that anyone listed in this thread except maybe the rogue AI....
  • Commented on We'll all go together when we go
    One thing to remember here is that humans are quite large animals with long reproductive cycle, i.e. precisely the qualities of animals that go extinct when things go wrong. And indeed we nearly went extinct before. All we need to...
