    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.




  • Good choice on Mint.

    I have been using Linux exclusively (personal) since 2008, distro hopped for a few years then settled on Ubuntu, until they shot themselves in the foot with 22.04 and the snap debacle; moved to Mint (after trying Pop, MX and a few others).

    I have to say a big well done to the Mint devs, it is better than Ubuntu ever was; part of this is newer drivers etc…but it is very polished and it gets out of my way and lets me do my work.

    Been working with the various flavors of Windows in a work capacity over the same stretch, in my opinion windows peaked with XP, 7 was ok, and 10 is also ok. But it really has been down hill since XP was retired.
