    A rotating spheroid will oblate when its centrifugal force generates enough inertia to slightly flatten it out into a more irregular, elliptical shape.

    I didn’t know inertia could be generated. I thought mass just had inertia. Could someone explain? Are they talking out of their ass or is that statement actually accurate?

      I think whoever wrote it just used the wrong word because yes inertia is dependent on mass, not momentum

      Okay I actually decided to check and I think it just a poorly written explanation of rotational inertia

      A rotating spheroid will oblate when its centrifugal force generates enough inertia angular momentum to slightly flatten it out into a more irregular, elliptical shape.

      If the shape also changes, this would mean distribution of that mass relative to the axis of rotation would also have changed, which if I’m reading this right, affects rotational inertia.

      They are talking about Moment of Inertia. Inertia wrt to rotation changes with how they are positioned in reference to the spinning axis. Think slender bodies are easier to rotate compared to wider bodies with same mass. That’s what they mean when earth slightly flattens out its becoming less slender and more difficult to rotate

    lol, I’m not trying to pick on someone with dyslexia but this was a pretty funny typo.

        How does this guy complaining about funding mean he lacks critical thinking? This place is more full of thoughtless agitprop than Reddit. Your botlike comment is useless and could be a response to anything. This place sucks lol

          Could it be something like the overall funding for an institution is not relevant to crowdsourcing one research project? Or maybe that no matter what you think about overall budget, that has nothing to do with trying to get millions of sensors in place? Or maybe that regardless of government funding, citizen participation in science is exciting and cool?

          Edit: or maybe it’s just a throwaway comment trying to stir outrage, rather than having any relevance to continuing a discussion

      Holy crap yeah, you can’t even build one high speed rail line with that! You couldn’t even rebuild the World Trade Center in NYC with that! That’s less than the Big Dig rebuilding a couple miles of highway in Boston! How are we keeping NASA so poor when they consistently deliver science that is both literally and figuratively out of this world?

      Until we can multiply that budget, “all your [phones] are belong to [NASA]”
