China completes most powerful hypergravity centrifuge

  Did a little research on this thing. Its capacity is 1900 g-tons, meaning that it can take a payload of 1000 kg (one metric ton) and spin it to apply 1900 G’s.

  Is 1 ton it’s weight limit? Dunno.

  Is it limited to 1900 G? Dunno.

  The “compressing space time” statement is just poor journalism. They’re referring to the fact that they can perform accelerated testing because of the higher limits. Basically, a test might take 2 days instead of 10 because it can go harder. Yes, it’s that stupid.

    You da real MVP.

    Its weight limit is 19 MN. You can divide it in any reasonable product of payload mass and apparent gravity you want.

    It would be way more practical to label it by the actual weight than that gravity*weight bullshit. But engineering has some boneheaded practices that people insist on keeping alive, mostly for gatekeeping.

      Doubt

      You’re assuming that it has the ability to spin faster at lower loading. There’s certainly an upper limit to how fast it can go (because of motor limits, gearing, etc).

      In reality, the limits for this machine are probably best described by a payload vs. speed chart.

  For some reason the ‘article’ mentions compressing space and time multiple times. Does it really though? Maybe I’m misunderstanding, but I can’t imagine large centrifugal forces inducing any relativistic effects.

    Only if it goes at a statistically significant % of the speed of light, I think. Artificial “gravity” it creates should not have any relativistic effects, AFAIK. These only show up at proximity to large masses (real gravity).

      And even 1900x Earth masses would have a time interval of 0.9999986774:1

  “Hypergravity” centrifuge? Isn’t that just a centrifuge? Are there any hypogravity centrifuges?

    Let’s define hyper gravity first…I have no idea what that could even mean
