    graph function singularities exist as physical features in our world

    Do they, though…?

    As I (mis?)understand it, as a massive star begins to collapse, getting denser and denser, the gravitational gradient gets steeper and steeper… and time (from the perspective of an outside observer) gets slower and slower… to the point that, from our point of view, the full collapse (or maybe even any collapse below the Schwarzschild radius?) hasn’t happened yet, and won’t happen until the extremely distant future, beyond the end of the universe…

    So, in that sense, from the point of view of “our world”, no singularities (except possibly the big bang) would ever exist (yet), all of them being censored not only by event horizons, but by being shoved into the perpetually far future, beyond time itself…

    And, speaking about event horizons, isn’t the whole “light isn’t fast enough to escape” concept a misinterpretation of sorts…? As I (again mis?)understand it, it’s not a matter of speed, but of geometry… The way space-time is twisted in such a gravitational gradient, once you get past the event horizon there are no longer any directions pointing towards the outside.

    Which is another from of cosmic censorship (or a different effect or interpretation of the above), preventing anything inside the event horizon from causally interacting with the outside universe…

    So, if these singularities are hidden beyond sight, causally, visually, and geometrically isolated from the rest of the universe, and perpetually shoved into the far future… can they really be said to exist in our world…?

    (Of course there’s always the big bang, but we can’t really observe that one, only its effects, and it’s not necessarily exactly what the original post was talking about anyway…)




  • Two things can both be wrong

    When one of those two things is fascism, the other one is irrelevant.

    The difference in magnitude between how wrong one objectively is and the other might be is so cosmically vast, that any comparison is moot.

    You either stop fascism, by any means necessary, or you (and everyone else) suffers the consequences.

    Again, there is no possible middle ground.

    There is no possible “yes, but…”.

    There are no other priorities.

    There’s no possible bargaining, rationalisation, justification, or argument.

    Any attempt at such is either irrational or malicious, or most probably both.

    When faced with an existential threat, you either do everything in your power to stop it, or you suffer its consequences, and allow everyone else to suffer them.

    If you are not actively opposing fascism, you are enabling it.

    You are a necessary accomplice and collaborator.

    You are effectively indistinguishable from any other fascist, and equally responsible for any harm they cause.

    Accept your responsibility and, if you don’t like it, stop trying to justify yourself and start doing something about it.


  • how is it also not a problem for people to violate immigration law

    Because they don’t give a flying fuck about whether the people they’re disappearing have violated any laws or not.

    They’ve disappeared citizens, they’ve disappeared people following the legal process to immigrate, without letting them finish, they’ve disappeared tourists who didn’t even have any intention to immigrate.

    They’re fascists. They don’t care about the law. It’s just an excuse to do what they want. Marketing to attract gullible racist idiots to their cause.

    But, even if that wasn’t enough, even if you don’t care about their real motives, even if you don’t care whether the law is good or not or how it’s applied, as I said in my previous answer they’re designing their new laws in such a way that it’s impossible for anyone not to violate them.

    Even if you were to always carry your parents’ and grandparents’ birth certificates on you, what about your great grandparents?

    Everyone in the USA is an immigrant or a descendant of immigrants! (Sure, some got there long enough ago that they were probably the first to arrive and can therefore be called natives, but they’re the wrong colour, so they don’t matter and will be disappeared anyway.)

    Ironically, the only people who’ll be able to prove they’re in the country legally (not that it matters, since, as I said, the fascists don’t care) will be those with a green card, properly stamped foreign passport, or similar documents.

    Making laws impossible to follow and then applying them arbitrarily to achieve their own goals and not the laws’ has been standard fascist fare since fascism was invented (and, before that, standard autocratic authoritarian fare).

    Watching fascists do their thing and pointing at the law and saying that their victims deserved it or should have known better is disingenuous at best, almost certainly malicious, and definitely monstrous.

    And I’ll finish with this:

    Not like the brazen giant of Greek fame,
    With conquering limbs astride from land to land;
    Here at our sea-washed, sunset gates shall stand
    A mighty woman with a torch, whose flame
    Is the imprisoned lightning, and her name Mother of Exiles.
    From her beacon-hand
    Glows world-wide welcome; her mild eyes command
    The air-bridged harbor that twin cities frame.

    “Keep, ancient lands, your storied pomp!” cries she
    With silent lips.
    "Give me your tired, your poor,
    Your huddled masses yearning to breathe free,
    The wretched refuse of your teeming shore.
    Send these, the homeless, tempest-tost to me,
    I lift my lamp beside the golden door!

    Now, I’m not an American, I don’t care about American nationalism or pride, but this is what America, the USA, was supposed to be, what it was supposed to mean. A nation of immigrants, welcoming liberty seeking refugees to her shores. A beacon of freedom and democracy to which everyone could aspire.

    Of course, it never really was that. But it was a nice thought.

    Something is clear, though; anyone justifying the current government’s actions in the name of defending America, or American ideals or culture is either extremely ignorant or an hypocrite. And they’re most definitely un-American.

    And I’ll finish with this

    Ah, no, wait, sorry, there’s also this:

    This is the problem I have that leaves me stuck in the middle.

    There’s no middle ground with fascists.

    You’re either actively against them, or you’re part of the problem.

    Maybe you’re one of them, or just a useful hateful racist idiot aiding and abetting them while you wait for your turn to be disappeared for not being fascist enough, but if you’re not fighting against them you’re contributing to their crimes against humanity.

    And if you’re just a useful idiot, bear this in mind:

    You won’t appease them. They won’t stop. They won’t thank you. They won’t hesitate to treat you like any other undesirable (including many who believed themselves to be part of their group). You’ll end up like any other “illegal immigrant” when your turn comes.

    And if they’re not stopped, rest assured, it will come.














  • in like sg1 which is more realistic to use, we would need aliens to give us the tech, because we would never be able to conceive on our own.

    Excuse me, we stole, I mean salvaged, most of that tech by ourselves, and we used it to kick goa’uld ass all over the galaxy (and, to be fair, they had stolen it first).

    Sure, some aliens did give us some tech, but only because we saved their scrawny hyper-advanced asses from their own hubris because, unlike them, we could conceive of hitting things with a big stick, or shooting small but fast metal pellets at them using barely controlled explosions (you know what, disregard the metal pellet and controlled explosions part, just throw C4 at the problem until it goes away!).

    Damn, I miss that series.
