  • The last time? aaaahahahaa… no. There are several phenomenon that require energy levels that only stellar objects can throw off. They’ll be asking for bigger colliders even when they’re dedicated space stations firing what would be equivalent to weapons of mass destruction at each other.

    Unless scientists can figure everything out just by observing space, there will always be a demand for a bigger collider. Since scientists like to control variables and don’t like waiting for random events that they then almost have to reverse-engineer to explain (without most all of the sensitive detectors built in to these colliders), there will always be a demand.










  • BTRFS is smart enough to check for file errors in some situations under normal operations (I forget which, it’s been a while). When it finds issues, it puts it in read only to try and prevent things from going off of potentially corrupt data.

    NTFS, which is what Windows usually uses, is a very “dumb” file system. It is merely a record of what files exist where, so if data corrupts, it will only throw NTFS off if it’s in the file index it stores itself. If it’s in the middle of your file, NTFS doesn’t know and doesn’t care and will just give you the wonky data.

    Windows seemingly continuing to work is just a consequence of the “dumb” file system. It will take some critical file getting corrupted before Windows or some program will just crash. At least BTRFS is trying to tell you things are looking amiss and you should definitely back up anything important.

    IIRC, isn’t it closer to a white hole, what with expansion? If you were far enough away, you cannot reach ‘there’ vs being guaranteed to reach ‘there’ like a black hole. Though really, it’s neither. Just curved spacetime.

    The fact we think of white holes and black holes as separate entities just goes to show our great lack of understanding of spacetime.

    Planck length is not like universal pixels. It’s just where current models say there’s little reason to look at smaller things, since it’s kind of like worrying about which flecks of paint are coming off a car in a racing video game. It’s just … so irrelevant as to be ignorable.

    It’s nigh impossible to have any energy that could interact with us or atoms on the Planck length scale that wouldn’t just collapse in to a black hole. It’s not so much any observation of real-world pixelation, and more that even to atoms, it’s very tiny.





  • Absolutely TONS of info, though I’m not a geologist, nor have I studied much, so I sadly do not know of any solid references I could simply point at. I’ve just picked up a few details over the years watching random geology videos on YouTube.

    GeologyHub makes frequent short videos on current activity, and he always comments on the mechanisms at play, and even makes and explains his educated guesses on what will happen. A plug forming comes up quite often when eruptions slow, even in eruptions that are destined to continue erupting.


  • Oh I get it! If you stack rock on the hot rock, you can stop the hot rock from moving the rock with more rock!

    … Unironically, this DOES work … sorta’. Though it’d be dumb to do by man, because a ‘rock plug’ is exactly what forms at the top of many volcanos after the magma cools. It’s why many volcanos have flank eruptions where magma pushes through some side crack, or build and build until the rock plug pops catastrophically.

    Of course some volcanos don’t have the right mix to form rock plugs, and any non-dormant volcano can pop them, but the point is it does have an effect that can delay and redirect eruptions.

    If humanity doesn’t kill itself off soon (bad news on that front), I wouldn’t be surprised if one day we’re building megastructures around volcanos specifically to manage them instead of being subject to them.
