    Given that quantum theory and general relativity are incompatible, something has to give.

    Also, general relativity requires dark matter and energy to explain cosmological data, but particle physics has yet to capture the faintest indication of something supposedly 5x more common than visible matter.

    In fairness sometimes small tiny differences like that do turn out to be significant. But measurement error usually wins out most of the time

      Then there’s things like:
      “Passing through the magnetic field, exactly half the electrons went UP, and exactly half the electrons went DOWN”, and classical physics went OUT through the quantum window.

      Cosmic metal?

      Is that some kind of refined variation of unobtanium?

      (Without reading more… I’m just going to assume they mean meteoric iron? Though the title does read like a prompt for a b-tier sci-fi that ends with Kirk trying to put his dick into something he absolutely shouldn’t put his dick into.)

      I enjoyed reading that. I’m no chemist or physicist, but that sounds like it could be a cool real world thing. Care to shatter my ignorance?

        From what I understand its a Nickel alloy that has good magnetic properties which can replace rare earth alloys for magnets that renewable technology is heavily reliant on. At face value yes this would be pretty big, but in terms of actual real world practicality on replacing rare earth magnets I really couldn’t tell you. Most science articles tend to oversell scientific breakthroughs in my experience, science is slow and incremental, if it’s a real breakthrough the technology tends to catch fire fairly quickly before any articles are written on it
