  • 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.




  • 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.










  • How?

    I’m in NZ, we have a whole bunch of politicians to choose from, and it always comes down to who is the least likely to fuck things up beyond repair. It is not often that an objectively good candidate, everyone has their flaws.

    In this example the question is not is Harris an objectively good candidate, but is she objectively better than Trump?

    In my opinion yes, yes she is! Trump is the worst, the way he has emboldened the far right world wide is truly terrible.

    Generational shifts happen slowly and in full view. You can act accordingly, this is a process that lasts decades.

    COVID happened in months, spread like wildfire and put a huge strain on healthcare systems worldwide. No amount of money thrown at the system would have increased capacity.

    What would count as real proof, if not prices falling due to competition?

    That is the problem I was referring to in my original post, “economics is a very murky science”, I come from an engineering and physical sciences point of view. Good economic data is hard to come by, it is always contaminated with chaotic factors that cannot be controlled for. “Proof” may not be possible in economic science.

    Why would it not be true?

    Because from a logical point of view, there is no necessity to go from socialism to communism. A country could easily decide that socialism is where they wan to stay. When something is necessarily true, not only does it always happen it must happen. That is the point I was trying to make, there is nothing fundamental about socialism forcing that transition from socialism to communism.

    Again, this has nothing to do with Socialism or Communism.

    I have to disagree with you there, in a capitalist system the burden of care falls on the individual (see the American health care system), whereas in socialism and communism, that burden falls on the state. This is a key economic factor, I’m from NZ and the social healthcare system is really awesome, but as with everything we can see how it could be better.

    The system has a capacity, if you want to increase that capacity you have to have the resources to do that. If your population is not growing (stable is not enough) then your health care system is always in danger of not having enough resource. The problem is that the system always need to grow, as we get better at improving the lives of people and increasing lifespan the burden from the elderly increases. The resources used to care for the elderly are finite and use up system capacity.

    Even in a capitalist society the system has capacity limits, there is no amount of money that you can throw at it to increase your number of doctors tomorrow. You have X doctors today, this is not easily increased beyond the natural rate (X+new doctors-retiring doctors), all you can do is move the existing ones around.

    You can use this argument for a lot of major points of expenditure; education, welfare, transport etc…but healthcare is starkly different between the different economic models.
