  1. The entire idea of the laser sail is that the craft itself can be very light, because the lasers are not on the craft.

  2.  @dontactlikeUdonkno  Yeah, he didn't talk about that in the video, I guess the starshot idea is to just fly by the target system? But I guess you could use electromagnetic breaking in addition to the light pressure of the star to slow down? Don't know whether that would suffice.

  3. I don't understand any of the physics, but the most well cited paper I could find is "Are black hole starships possible?" by Crane and Westmoreland. And when I look at the citations on google scholar the first one's titled "No black holes from light" and came out this year.

  4.  @CoolWorldsLab  Huh, you cited that black hole drive paper, too. :D

  5. They're very relevant for understanding our own past and future.

  6. People have already left earth. And your religion is horrible whether you're on earth or anywhere else.

  7.  @AlexWalkerSmith  That's stupid. Having elvolved somewhere doesn't mean you're happier there. Actually the opposite is the case: it means you're probably unhappy there, bcs unhappiness is pretty much always correlated with your evolved seeking and avoiding behavior. You evolved to be miserable in your environment.

  8.  @AndrewBlucher  Lots of small senders spread apart are a lot like one large sender.

  9. Is there a god, who puts kangaroos in all rooms? No. Bcs there is no kangaroo in my room. Same goes for FTL/time travel.

  10. Intuitively that seems totally implausible. Have you crunshed the numbers and found out that you could do sth with a laser pointed at another solar system?

  11. For interstellar travel itself it doesn't matter whether one individual in the same body arrives or their descendants or an artificial agent. All of those are subject to mutation.

  12.  @Klyis  >There's records of nearly every great leader of the ancient world seeking out the wisest men in their lands to discover the key to eternal life Can't think of any.

  13. You could, e.g. move stars closer together to have more reachable neighbours.

  14. There's literally a video on this very channel discussing the concrete reasons we can't build an Alcubierre drive. The consideration of the consequences comes ON TOP of that, so that even the those reasons can somehow be overcome, it's still incredibly implausible that it could work, bcs otherwise there should already be Alcubierre spaceships everywhere and indeed there should be the kind of infinite resonance effect mentioned in the video. Why isn't there someone, who can and wants to eat all cookies in the world in ten seconds? Lots of reasons, but we also know that he doesn't exist.

  15. Not really. Just bcs something is a valid metric in GR doesn't mean it can exist. Similarly you can describe systems in Newtonian physics that you can't build. Also again: if it existed, why isn't it already here due to timetravel?

  16. I guess the laser sail slows down at the other end via electromagnetic breaking in addition to the light pressure of the target star? Or is the idea here just to shoot by?

  17. 1) A lot of this has been built. 2) If we can never talk about any potential future technology, we could never have invented ANY technology. Genuinely don't know whether you're acting dumb on purpose.

  18. 1) It being nothing like you expected would be more exciting than it being exactly like expected. 2) Why would you be stuck there?

  19. >due to ever increasing costs Increasing costs of what? >It's all fun and games until you start crunching the numbers. I am 100% sure that you have never "crunched" numbers in your lifetime.

  20. By definition AGI is at least as good as humans at everything we care about. Also imo Nick Bostrom convincingly argued that being at a human level in silico makes you immediately vastly superhuman. So even the smartest of us helping the AGI would be like a toddler helping a rocket engineer.

  21.  @AndrewBlucher  You're a particularly pompous idiot. 1) Being a scientist yourself in no way means you're better able to speak on speculative engineering. And not being a scientist doesn't mean you can't. Most scientists have no clue about this, even most physicists don't. 2) Having published well cited stuff yourself has absolutely nothing to do with being well informed about a subject matter. If anything the opposite is the case: if you're doing a lot of original research, you probably don't have the time to be informed.

  22. Your insane rant aside, the space between galaxies expanding isn't the same as a craft moving between galaxies superluminally. Nothing actually travels faster than light in the first case.

  23. If she said that, she's wrong. Any superluminal travel would be time travel. Where do you think she claimed that?
    1
  24. Are you saying that it's somehow possible to build alcubierre drives, but they are somehow limited to moving subluminally? Or are you saying that alcubierre drives exist and everyone exclusively moves subluminally with them?

  25. >Paradoxes could be avoided if the multiverse hypothesis No. FTL leads to time travel in this one universe.

  26.  @invisiblekincajou  Hydrogen bombs literally have never been used. So that's a strike against your argument if anything. Meanwhile knives are still used all the time.

  27. You're probably thinking of an erroneous interpretation of the delayed choice quantum eraser. It only violates causatily if you totally ignore quantum mechanics. What exists in quantum mechanics is the wave function, the superposition. Heck, even the Wikipedia article has a section called "Consensus: no retrocausality".

  28.  @guidojones6107  Not sure what you're getting at. You still need a shield for a larger interstellar craft.

  29. Why didn't you consult the literature of people, who already thought about this problem, lol? If you can't find it, other chatbots like Perplexity can actually find sources for you. If there's a common misconception about sth, Chat-GPT is likely to pick it up as well.

  30. The Buzzard Ramjet was mentioned. Afaik that's the most prominent fusion drive.

  31. >Special relativity allows for time travel That's like saying Newtonian mechanics allows for pink flying elephants. > and it does not violate causality because past events has no causal power in the present That's complete hogwash. Causality violation and time travel are the exact same thing in special relativity.
