    I’m in the space industry and I can tell you that anyone pretending to be an authority on orbital mechanics on the internet is full of shit. I’ve taken entire classes called “advanced orbital mechanics.” That shit is wildly hard, vaguely inaccurate, and so slow that you can only do it effectively on a computer. Even then you have to decide which variables to throw out because you if you use them all you won’t be able to calculate predictions on every satellite in time for them to be useful. Then you have to take the predictions, predict how wrong they are, and predict again based on those predictions if two satellites will run into each other.

    The truth is that nobody knows if Kessler Syndrome is even real. I personally fall on the side of thinking it’s nonsense, there are too many variables that would have to go wrong all at once. It’s like being worried about winning the lottery. There have been multiple catastrophic on orbit conjunctions that have created thousands of pieces of debris. Still no Kessler Syndrome. Even in a nightmare scenario I can only see it affecting one orbital regime. The odds of Starlink effecting the orbit that GPS is in is effectively not possible. But this is not a solved field and I am not remotely an expert, I’m just tired of people who don’t know a thing about the field thinking they’re experts because they have a JWST desktop wallpaper and have 300 hours in KSP. The real experts are ancient old men and women who have been doing orbital predictions for 40 years and I’ve seen them get into yelling matches about this sort of thing.

    This post got away from me but the point is this shit is so involved it effectively can’t be fact checked because you could come to whatever conclusion you want.

    I left not too long ago, it’s gotten significantly warmer. Rained every week of summer. I think it hit 60 one day. The tow is closed because the permafrost underneath shifted and the building is cracking in half.






  • The end of WW2 was a complex political issue, and the atomic bombs were not the ‘press here, end war’ that most of us believe.

    The Japanese we’re holding out hope (stupidly) that the Soviet Union would negotiate a conditional surrender with the united States as the end of the imperial system was unacceptable to them. The US had floated that if there was an unconditional surrender, that the imperial system would stay intact, but wanted it to seem like a US condition, not a Japanese one, because that would be a conditional surrender.

    The Soviets always intended to invade, but were held by a nonaggression pact they made with the Japanese. The US pressured the Soviets very hard to violate this and invade Manchuria.

    There was literally a Japanese war cabinet convened already when news of Nagasaki reached them. We have actual primary source for their reactions. They did not care.

    Only once the second bomb dropped and Manchuria was invaded did some of the cabinet manage to convince the emporer to intervene which was extremely rare.

    Correct. I’ll happily shill for the defensive alliance formed to ward off (the currently on display) Russian aggression. NATO would not exist if Russia weren’t so nakedly attempting to rebuild the Soviet Union by force, an alliance that had already been litigated and abandoned by the smaller nations Russia pillaged for resources, this time without even pretending to be for the workers.

    Edit: no amount of tankie brigading will convince me that Russia isn’t the aggressor in the region. Imagine the brainrot required to think that the military that invaded Ukraine and is still currently there is the good team.




  • Highly doubtful much of anything majorly sensitive got leaked. Firstly even unclassified DoD emails are encrypted by default. Secondly anything classified isn’t even on a network that can talk to normal email, it’s either 100% point to point encrypted or on an airgapped network. If I hopped on SIPR (DoD Secret-level internet) and emailed a normal email address it simply wouldn’t work.
