minus-squarecevn@lemmy.worldlinkfedilinkarrow-up9·3 months agoI knew my crap science would get the real scientists in the comments, good point about the density. It would just sort of harmlessly splat.
minus-squarepeopleproblems@lemmy.worldlinkfedilinkarrow-up5·3 months agoNow hold on, I did my math wrong. It was far too late at night. I used C=300000 not 3*10^8. That gives us an impact energy, classically, of 5.37*10^41 J. So that is about 3 times the kinetic energy than the engery at rest of Sol. Sol is not at rest, further, we have non- insignificant factors at play here. Sol is orbiting Sagittarius A* at 250km/s. Additionally, we have the general relativistic relationship between Sol and our massive projectile. I’m going to work on modeling this, it got far more interesting.
