Best way to leave the milky way is probably to slingshot around a black hole. Stars get ejected from galaxies all the time like this

Hey not here to talk about any of the weird consciousness stuff, just science, came back to this thread because I was interested in what you were saying about relativity. Like aren't event horizons as found in black holes and the cosmic horizon the same thing?

It's my understanding that it's not possible to synchronize two clocks without bringing them together. And regardless if two clocks are separated by an event horizon (i.e one of them fell into a black hole) or if they're separated by the cosmic horizon (i.e one is outside the observable universe) they can't ever be brought together. Doesn't that mean you can't meaningfully define a moment in time that is simultaneous for them?

Like in the case of a clock inside a black hole, that's in the infinite future of another clock outside the black hole, right?

That's kind of what I was thinking, but she did say she comes here often anyway so I'm not sure

Oh yeah for sure, I did not contact her intending to ask her out lol. It was only after how enthusiastic she was that I started thinking about it, and I'm still not even sure I'll do it, waiting to see how our in person interaction goes first. I'm totally cool staying friends with her if she's not interested!

I really recommend watching Scavengers Reign for anyone who finds this type of thing interesting! I guess it's probably not scientifically accurate from a speculative evolution point of view, but wow the level of thought and detail put into the alien ecosystem is mind blowing. Really beautiful show.

I don't know why you'd ship actual live beings across interstellar distances. Either implies there's a way around the speed of light, or somebody is really fucking bored. The later is of course more likely.

I can see it for the closest star systems to ours, the dozen or so stars within about 10 light years of the Sun. If we can get a spacecraft to 90% of the speed of light, time dilation cuts the elapsed time aboard the ship down to 43 percent of the elapsed time on Earth. The crew would perceive getting to Alpha Centauri in just 1.84 years.

This shit is what makes me doom the hardest. This century is going to spill an incomprehensible sea of blood incomparable to anything else in literally the entirety of human history.

Similar to when these shithead libs say that we've been brainwashed by Russian/Chinese propaganda and we're all useful idiots for the redfash menace

Like motherfucker, do you hear yourself? I live in the fucking United States, I speak English, if it were just that I'm extra susceptible to propaganda, why the fuck am I falling for another country's with massive language and culture barriers instead of just being really well propagandized by the constant incessant torrent of capitalist propaganda exploding out of every orifice of the mainstream liberal media in this country?
