intergalactic travel part is really really underexplored, there’s pretty much nobody considering it, so I guess this post series is the field-founding work.
Edited. Thanks for that. I guess I managed to miss both of those, I was mainly going off of the indispensable and extremely thorough Atomic Rockets site having extremely little discussion of intergalactic missions as opposed to interstellar missions.
It looks like there are some spots where me and Armstrong converged on the same strategy (using lasers to launch probes), but we seem to disagree about how big of a deal dust shielding is, how hard deceleration is, and what strategy to use for deceleration.
:) Ok, and now I will take a chance to advertise my two ideas of intergalactic colonisation.
First is a SETI-attack—that is sending AI-contaminated messages to possible naive civilizations. LW post. Not sure we should start it.
Second is the use of a nanoprobe’s accelerator to send many nanoprobes with different speeds—such nanoprobes will reach each other in the flight and organise in large obejct, which will then capable to deceleration—more details in the comment to the deceleration post.
Claiming that
is annoying as there is an excellent work by Armstrong “Eternity in six hours” https://www.sciencedirect.com/science/article/pii/S0094576513001148
and there was LW post about decelerating of the intergalactic probes. https://www.lesswrong.com/posts/WnPa2KyaTcLXRYZp8/decelerating-laser-vs-gun-vs-rocket
