    Over a month later I still have no real clue what this means.

    Maybe that's how we came to exist, invented in a lab by some reptile in a lab coat. It would explain a lot.

    There's a UVM connection with that research. Which is interesting, because a different [and since former] CS faculty member was not very keen on self replicating nanobots and assigned a lot of articles about the dangers of them during Senior Seminar for my CS degree. 22 years ago. The "grey goop" theory of how the world would end. Now they've gone and done it.

    I think in about a month I won't know, either.

    But at the time I was thinking the magnetic tunnel thing might alter incoming radio waves--it shouldn't take a lot to turn a signal into noise. In which case SETI's failure to find the aliens with radio telescopes might have alternate explanations. Maybe the answer to Fermi's paradox is "the tunnel's hiding them."

    Gotcha. Although I think it's more likely that they're hiding themselves.

    Good point. And if the tunnel is worth a damn it might make that super easy.

    It's finally there. This could have hudge impacts

    CAPE CANAVERAL, Fla. (AP) — A NASA spacecraft has officially “touched” the sun, plunging through the unexplored solar atmosphere known as the corona.

    Scientists announced the news Tuesday during a meeting of the American Geophysical Union.

    The Parker Solar Probe actually flew through the corona in April during the spacecraft’s eighth close approach to the sun. Scientists said it took a few months to get the data back and then several more months to confirm.

    “Fascinatingly exciting,” said project scientist Nour Raouafi of Johns Hopkins University.

    Launched in 2018, Parker was 8 million miles (13 million kilometers) from the center of the sun when it first crossed the jagged, uneven boundary between the solar atmosphere and outgoing solar wind. The spacecraft dipped in and out of the corona at least three times, each a smooth transition, according to scientists.

    I can't imagine how nervous that team will be as the engines fire up.

    Not really that cool or impressive, none the less…

    Visiting family members in Oak Ridge Tennessee this weekend, one family member was cleaning out old possessions and brought a number old watches for anyone that wanted one.

    He mentioned one of them used to glow in the dark. Immediately my nerd brother in law perks up, he’s in R&D at Oak Ridge.

    He describes to us all how they used to used Radium to illuminate watches and proceeds to run home to grab his geiger counter.

    I’m pretty sure he keeps his college era counter as a retro demonstration device, but it was cool to see it work. He’s active in scouts and the local school district so of course he had props.

    After demonstrating the radioactivity of fiestaware and coleman lantern mantles it was proven that the watch was indeed radioactive. Not like melt your face but you wouldn’t want to lick it type radioactive.

    I’ve seen geiger counters in movies, but was today years old before I saw one in person.

    They painted the radium on those watches and the workers would lick their brushes to keep a nice sharp tip. If you want to see how that worked out for them do an image search for "radium mouth."

    "Ötzi and the Radium Mouths" would be a good name for a band.

    Butchering pronunciation is what happens when you have radium mouth.

    Surf instrumentals, as you might hear on the beach at Three Mile Island or while catching waves on a Fukushima tsunami.

    Osteonecrosis of the mandible sounds like a pretty awful way to die.

    My favorite explanation;
    "And obviously, the alien factor could not be missing, with a Type III supercivilization on the Kardashev scale expanding through a vacuum, absorbing energy from nearby galaxies."

    This is cool. Who knows if it will ever by viable, but it's exciting if they could make it work.
