  • As far as we can figure it, basically, yeah. Wrapping your brain around the concept is less tricky than you’d think.

    So gravity gets stronger the closer you are to a black hole, but at the event horizon things get weird. The extreme curvature of spacetime forces space itself to flow toward the singularity at its center faster than the speed of light, so on the inside there’s no “other” direction to point to, even photons emitted straight “out” can’t reach the event horizon and end up moving in the same direction as everything else. So space becomes timelike, proceeding inexorably from point A to B.

    Time is more complicated, because it’s really hard to visualize. If you fall into a black hole, you’ll pass through all the outward-pointing light that’s been failing to escape since the event horizon formed, which puts all the past history of the black hole below you. Meanwhile, anything that falls into the black hole after you but before you hit the singularity can be seen falling from above as the downward-pointing photons catch up. The timeline of the inside of the black hole is laid out with the past and future being directions you can point to, making time spacelike.


  • Okay!

    Entanglement is what we call any sort of quantum interaction that causes some property of two particles to become linked, like photon gun that always spits out two photons of the same polarization, or bouncing a couple of molecules together so that they spin in opposite directions. So long as nothing comes along to disrupt that state, we could measure one particle and we’d know the state of the other particle no matter where it is without having to measure it.

    The “inexplicable connection” there is just information about a quantum pair, but it’s spooky because that information literally doesn’t exist until it is measured, at which point the connection is broken. A couple of intergalactic hydrogen atoms could exchange a photon across light years and become entangled for the rest of time, casually sharing some quantum secret as they coast to infinity.

    Bonus answer, I think time is real but isn’t like what we imagine it to be.



  • Yes you people. Fuck off with the faux outrage.

    I’m not outraged, I’m confused. Who is “you people” supposed to be referring to?

    She’s a politician that did a stupid politician thing. It’s so fucking stupid to give a single shit about it.

    And yet, here you are getting mad because people didn’t give enough of a shit about it.

    Clearly it failed. But it’s a really fucking stupid reason to not vote for her. Just completely ignorant of the political reality we were in.

    Says the guy trying to blame the voters in a country that science says is not and has never been a democracy.


  • Man you people are a bunch of fucking snowflakes after all aren’t you?

    “You people”?

    Throw a hissy fit because the only viable candidate that wasn’t going to quite literally destroy our democracy didn’t turn out perfect.

    Who are you talking about? Harris destroyed her own campaign by squandering all the momentum gained from dropping Biden off the ticket.

    She was never a viable candidate because she chose to fight right-wing populism with mealy-mouthed bipartisanship.

    If you haven’t grasped it yet, I’m not sure you’re capable of understanding. You even said yourself that she, “tried to appeal to” those people, which implies that you understand that it was 100% a political move to try to get votes.

    I genuinely do not understand what your point is. It sounds like you’ve got your understanding of electoral politics backwards, the onus is on political parties to earn our votes and parties that can’t convince people to vote for them lose elections. Individual choice doesn’t matter, what matters is who has the best propaganda.
