    The reason you need to slow down is because you’re starting on Earth, which means you’re moving fast enough parallel to the sun’s surface that for every foot you fall downwards toward the sun, the sun’s surface curves away by 1 foot. This results in the nearly circular orbit around the sun we exist in.

    If you start speeding up, the orbit becomes more elliptical, except your aphelion starts raising away from the sun because now you’re moving fast enough that you’ve moved more than 1 foot sideways in the time you’ve fallen 1 foot downwards.

    Slowing down has the opposite effect. If you get your speed down to 0, you’ll fall straight down toward the sun as normal with gravity. But you don’t need to go all the way down to 0 velocity to enter the sun, you just need to slow down until your elliptical orbit brushes up against the sun’s surface. If you then want to speed back up to avoid falling into the sun, you need to do it parallel to the sun’s surface. At this point, speeding up toward the sun will actually make you fall into the sun faster.

    So basically the problem isn’t that you’re moving too fast to fall into the sun. By virtue of Earth’s orbit, you’re moving too fast in a direction away from hitting the sun’s surface.



  • Ukraine hasn’t even been independent for my entire life, what are you talking about? Do you think thirty years is a long time? Are you twelve?

    This is the thing that gets me with lemmy libs at times. I want to dunk on them harder, but some of them are so naive and ignorant about basic facts of recent history that in the back of my mind I can’t help but think I’m probably talking to an actual, literal child. Then I just feel saddened about it more than anything.




  • At what point did this become Russia’s aggression? Certainly after the fall of the Soviet Union by western backed coup (before which Ukraine and Russia were literally the same country). Did Russia’s aggression start when NATO aggressively expanded into the former Eastern bloc after promising not to as a major condition of the USSR’s dissolution? How about when Russia subjected its own population to devastating austerity, resulting in untold death and destruction, all in a genuine effort to liberalize and assimilate into NATO themselves? Was that Russia being too aggressive? Or did Russia’s aggression not start until after the west continued to wage economic warfare anyway, demonstrating NATO never had any intention to let Russia coexist peacefully on the world stage regardless? How aggressive was it of Russia when the west helped to orchestrate the 2014 Maidan coup in Ukraine to install a rabidly anti-Russian fascist government on one of Russia’s largest land borders? I guess Russia was being too aggressive when Ukraine decided to ban the Russian language and shell Russian speaking civilians in Eastern Ukraine for literally years and years in violation of the Minsk agreements, resulting in massive pro-Russian separatist movements forming to fight off Banderite pogroms.

    I think I get it now, after exhausting literally all available diplomatic avenues to peace, aggressive Russia started this conflict out of nowhere by supporting the cause of the breakaway republics invading poor innocent Ukraine, wow can’t believe a country would go to war like this at the drop of a hat! Irrational aggressive Russia should just take their troops home and surrender all territory back to Ukraine, a country losing a war so badly it’s on the verge of collapse.





  • Understanding classical waves better is what helped me wrap my mind around the physical meaning of the uncertainty principle. It’s not a technical limitation, and it’s not just because you need to interact with something to measure it. It’s just a property of waves. Since small enough particles exhibit the properties of waves, it only makes sense that we can’t know their location and momentum at the same time with arbitrary precision.

    The velocity of a wave is a function of its frequency and wavelength. But imagine a highly localized wave, essentially just a peak. What’s its frequency? Well, we find that it doesn’t have one frequency! If you decompose the wave, you find its mathematically a superposition of multiple sine or cosine functions with different frequencies and therefore velocities. So the more localized the wave is, i.e the more you know its position, the less and less you know about its frequency and therefore velocity.

    This stuff blew my mind when it was first explained to me.

    Don’t worry, you may not live in the US, but you’re definitely an American in spirit.

    And you clearly don’t seem to have problem with US prison system, only that wrong people are sent there. You’re as full of shit as the people you think you’re criticizing

    Soviet Union: Sequesters fascists and counter-revolutionaries for reeducation after Nazi Germany murdered millions of people while invading the USSR with the express purpose of genocide.

    The US: Uses drug prohibition as a bullshit excuse to systematically arrests racial minorities in their millions in order to continue enslavement after the abolition of chattel slavery. The conditions are so brutal that the death rate for modern US prison inmates exceeds that of the Soviet gulag system just a decade into recovering from the devastation wrought by WW2.

    Lemmitor turbolib: Wow, these are morally equivalent. If you replace the words “fascist comprador looking to resume the brutalization of the working class” with the words “black people” then you tankies are starting to look an awful lot like 4channers!

    lmao this lemmitors comparing Hexbear users to 4channers shit never gets old. When you liberals meet someone far to your left it must really break your brain for you to lump us in with fascists.

    You know what I almost never see referred to as edgy out of hand? People who don’t want to fully abolish the US prison system, which to this day kills far more people far more often than the Soviet gulag system did shortly after the end of WW2. And that’s really strange considering the US prison system is designed from the ground up to maintain a pool of slave labor by incarcerating racial minorities on bullshit drug offenses. Personally, I’d much rather prison be used to keep dangerous reactionaries from causing trouble while they’re being reeducated.

    Talking to someone who justifies this kinda shit is always a trip. They’ll say that people who aren’t earning a living wage just need to work harder and pick up a marketable skill to improve their situation. But you can simultaneously get them to agree that many of these low wage “unskilled” jobs need to exist for society to continue functioning, so which fucking is it?

    The answer is that the capitalist parasites and their horde of boot lickers believe it’s totally acceptable for there to exist an underclass of human beings born to work until their bodies give out for the enrichment of their superior employer.

    They can’t afford to live a dignified life doing the shit I need them to do? That’s fine, just toss 'em into the hole when they stop working and replace them with the next generation.

    Honestly man, I’m getting real sick and tired of pretending to be above violent retribution when it comes to these people. My blood fucking boils each and every time I need to look my boss in the eye and pretend to smile as they say farcical shit like “we’re all a family here” or “let us know if there’s anything you need” while paying me exactly the minimum wage and hiring the exact number of employees it takes for them to avoid giving any of us enough hours to qualify for benefits.

    Anyway, Stalin had the right idea with gulags, and we should bring those back. Thanks for coming to my TED talk






  • And yet the United States continues to slide into fascism despite having elected Biden. What horrific Trump era policies did the Democrats even bother to repeal after they won in 2020 and held both the senate and the house?

    They are still funding the construction of border wall segments. They never repealed the Republican tax cuts. They have done nothing about the concentration camps on the southern border for fuck’s sake. They never codified Roe v. Wade, we literally lost the right to abortions while Biden was in office. They could have stacked the supreme court but they didn’t.

    The Democrats and the Republicans form an obfuscated one party system in the US. Republican leadership aggressively ramps up the oppression of marginalized people, then Democratic leadership does nothing to restore our rights nor proactively prevent the same thing from happening again. Instead they just use their time in office to suck all of the energy out of people’s movements that could actually effect change.

    And much more importantly than all of that, Republicans and Democrats are virtually identically evil when it comes to foreign policy. When the US is dropping bombs on you and destroying your country, you’ll tend not to care whether it was a Red MAGA or Blue MAGA administration pulling the trigger.

    In some specific cases it might be worthwhile to vote for Democrats in local elections where there exists much more leeway for politicians to stray from the party line, but voting for them in national elections is just lending your voice to legitimizing their bullshit good cop/bad cop routine they play with the Republicans.
