  • Feynman, taught me it’s okay to question people, people grow when they’re questioned, and it isn’t wrong to speak up when you don’t know something even if everyone else seems to know that thing, because maybe group think has everyone assuming everybody else knows what’s going on, and that’s when shit can go seriously wrong.

    Terrible pop science, and people who are happily ignorant as long as it’s for the lulz.

    I’ve studied enough oceanography to know that this is bullshit.

    But if you want a community that isn’t critical of bullshit, well there are plenty of religious organizations that would love you membership.

    Sorry, what?? There are no hydro thermal vents at the surface of the ocean???

    Fucking biologist needs to go back to school.

    There’s no life at hydro thermal vents at the surface of the ocean because there are much safer and more reliable ways to get energy, but there are absolutely areas of active geothermal extremes at the surface of the ocean.

    Hell there are hydro thermal vent remnants in the coastal ranges above sea level.

    What does engulfing the earth mean to you? The mass of the sun expanded to a body 1 au would not be very dense. My money says the earth would continue to orbit “inside the sun” for quite a while, but the orbit would degrade more quickly.

    But yes, I argue get them out of the earths gravity well and let Newton handle the rest, no reason to propel them in any direction, eventually they’ll get to the sun.

    You are making 2 opposing assumptions there, 1) there is nothing to bump into in outer space, the earth picks up 43 tons of new mass every day.

    1. the earths orbit would decay, the earth is absolutely massive compared to the amount of mass gained, and also off gasses a significant amount of mass every day.

    If orbits don’t decay, why do even high orbit satellites need to make elevation corrections?

    If you put a small body into outer space it would absolutely be (slowly) effected by the miasma of particles out there.

    And let’s not forget we don’t have a time table for reaching the sun, and we aren’t aiming for the middle of the sun to see results. And as you approach the sun you will bump into more and more particles as they too are being drawn around the sun.

    It’s an easy talking point from the Internet and high school text books, it is disregarding of many actualities of our universe. It would be true if the sun were an infinitely small point on a 2 dimensional plane with a perfect lack of friction.

    And while for instantaneous results it would be easier to get something out of the sun’s gravity well rather than hit the exact middle of the sun, practically, if you have time, and you don’t actually need it to hit dead center of the sun, it’s much cheaper and easier to incinerate something proximal to the sun than it is too send it out of the solar system.

    Also let’s not forget gravity sling shots work in both directions.
