  • But it takes wiggling magnetic fields to confine fusion reactions, seems like taking energy from inefficient containment, or there’s more energy than required being used on containment which is lowering the overall efficiency…

    I am just a chemist.

    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.







  • This makes me happy, not giddy, not excited, but there’s something waiting for me that’s absolutely incomprehensible.

    Twenty years ago it would’ve kept me up at night and made me cry silently into my pillow.

    Many years ago I noticed I’d get those thoughts when I stayed up too late into the morning wasting my time away, and I would panic and spiral, but when I woke up I’d barely have memory of those thoughts.

    Now when I stay up to late and I get those thoughts I know it’s time to go to bed, I just accept that they come, and I know that they’ll be there, they just don’t bother me. Very much like my eventual demise.

    If they’re intrusive you probably haven’t had enough time to contemplate them. Live with them a while and you’ll find them to be another part of existence, and they’ll make you appreciate your existence, no matter how temporary, even more.

    And don’t ever believe anyone who says they know what happen to them/you the moments following your demise, they only hope to make your time with this existence benefit themselves.
