  • You are applying too much classical thinking.

    Something in superposition isn’t in some unknowable but definite position before measurement.

    It is all possible states, at the same time.

    Einstein famously did not like the implications of QM, saying “god does not play dice with the universe”, though his work on the photo electric effect helped pave the way for QM.

    This is just a misunderstanding of superposition.

    A superposition is being in all possible states before “collapsing” into a defined state, after interacting with something (a measuring device).

    So Schrodinger’s immigrant will be in all possible states; they are obviously lazy welfare bums; whilst simultaneously taking all the jobs; and being so poor that they eat your pets; and having the time to organize groups to go raping; whilst also being trustworthy enough to be a housekeeper or nanny




  • We know something is out there; galaxies are rotating far too quickly for our understanding of gravity to be correct. This is based on the observable matter.

    For the galaxies to be rotating at the speeds we observe, we need approx 5 times the matter we see. So it is not like we have missed 10 - 20% of the matter that interacts with electromagnetic radiation, we would have had to have missed an extra 500%

    As someone else pointed out, MOND is the next most promising candidate, but it has major issues even explaining what we see. Which is why it hasn’t received widespread acceptance.

    I don’t have an answer; I have a few ideas. It maybe that something MOND adjacent is the answer; i.e. on the largest scales spacetime “relaxes” more when there is nothing pulling on it. So near galaxies and clusters spacetime is under more stress, this stress could equate to spacetime curving more on galaxy sized scales. But on the small scales we work on the extra stress will be almost invisible.

    But as for us figuring out what “dark” matter is in your lifetime, unless you are already in your 80’s; I think there is a very good chance. The only thing we know for sure about dark matter, is that it interacts with gravity (spacetime). We are building some pretty epic gravitational wave detectors, bringing the detection threshold lower.










  • As someone with a 5yo.

    Sit on the floor when interacting with them. Literally being on their level can help a lot, that and talk about stuff they are into.

    As someone else mentioned, don’t baby talk to them, unless they have some specific learning disability, a 5yo will know a lot about what they are into (a dinosaur kid will know heaps about dinosaurs)

    My boys all love Lego, build cool stuff, then let them have it, don’t use instructions.


  • Cactus Outdoor.

    I had the original pack now called Vacuole, used it for a long time 10 or so years, lost it one time when moving houses. My boys have one each for school now, I expect them to last for the duration.

    I have two pairs of supertrousers and two pairs of hangdog shorts, all have lasted 6 years so far, daily use in summer / winter for the shorts / trousers.

    The stuff made in the Christchurch factory is epic.
