      The only problem is if the pursuing fleet were AI and robotic based, then they would likely induce the automated forces you leave behind and decoy fleets by standard light speed communication to join them and reveal their locations.
      Now what if the original pursuit fleet were biological, but over time and many cycles of this happening the fleet that is pursuing you is eventually essentially your own creation ?

    While flying through a red giant seems like the ideal place to scatter, even with fake ships made to be as reflective or emissive as the real ones but acting as decoys, all while utilizing the gravity well of most of the star including it's core to manouvre and change directions and speeds for all those real and/or fake scatering ships. One ship goes in, a myriad of ships go out in many directions. All seam real until the pursuers get close enough to see that all of them except one is made of the 35th century equivalent of cardboard.
    Interesting idea for whoever wants to use it in a hard scifi space opera.

      As a bonus you could have each of the decoys be capable of assembling/dissembling into Von Neumann probes that can act to seed and rebuild civilization from a saved information bank so any which the enemy ignores or misses can grow again to become an advanced civilization. Of course this requires you to have prepared for the possibility of needing to flee prefect for the paranoid civilization obsessed with preserving their existence.
      It might actually be a good "origin" for the aliens which masquerade as gods in one of my science fantasy settings given that the idea was they were refugees fleeing something which caught up to them and wiped them out resulting in their gods vanishing and an ensuing dark age where knowledge is lost. Cue science eventually advancing and reaching the space age and rather than pristine asteroids and planets they find wreckages of the alien ships/space stations in tattered ruins. Whoever did it left leaving them and their world behind albeit picked clean of all advanced alien technology.
      Just imagine that revelation you are in a long cold war space race analog looking out at the solar system and you find dead alien ruins the ruins are partially stripped of whatever the perpetrators took away presumably the technology the so called gods had used to rule over "mere mortals" and travel between the stars and all the knowledge stored within the ruined vessels but everything else is left derelict.
      No knowledge or evidence would be left of the attackers so they would be left to speculate under the existential dread that someone came and wiped out alien beings so powerful they were thought as gods and then left selectively removing some technology but leaving everything else. What happened?, What did they remove and why? Might the attackers return and if so how do they avoid meeting the same fate? So many questions to worry about and how might they shape society? :P

    If the fleet is fleeing rather than spend a huge armada, send just enough to make them afraid enough to continue to flee. Say automate a robot fleet to noisily chase, but never catch the enemy fleet. The persuit fleet being a robotic hound fleet chasing the fleeing fleet, allows your civilization to advances far beyond anything the fleeing fleet could contend with.

      I think the designers of the metric system realised that, too. That's why we've got the prefix system. It's a linguistic version of scientific notation, just quantised to multiples of three (well, if you ignore the prefix cluster around unity (centi, deci, deca, and hecto) that gets little use with most units).

    The telling of life among the evacuation fleets you described reminds me of an episode of Metal Hurlant Chronicles. They showed the remnants of a destroyed civilization and what was left on ships headed toward an uncertain future. Also you talked about the large arrays. In the Honor Harrington universe. Each star nation uses massive arrays thousands of kilometers in length to detect hyper footprints light centuries away.

    • @achtsekundenfurz7876
      @achtsekundenfurz7876 2 года назад +1

      IIRC, the detection ranges in HH are lower, more like hundreds of _light-days_ instead of light-years. The prime concern seems to be relativistic kill missiles released from half a light year away, with a few years time to target. Any more, and it wouldn't be an effective weapon in political time scales (all major HH polities have FTL, so they're synchronized pretty well), no use in launching an attack that'll hit a century later, possibly long after even the longest war has ended.
      What's measured in hundreds of LY is the diameter of a major polity (called "star nation"), and most space junctions (a small region of space that allows ships to cross some space instantly, to appear at the other end which is usually many LY away). Manticore, the POV polity for most of the books, is in possession of a particularly useful junction, with the "hub" in the vicinity of the Manticore system (about one light-day out) and as many as six outer endpoints, each more than 100 LY away.

    On the matter of inbreeding, go check on the Hawaiian royalty - inbreeding there was mandatory, and the closer the familial relationship, the more prestigious they considered it. And yet, it appears they were healthier, stronger, and all around better than the rest of the populace, not merely because, being royal, they had access to more and better resources, but genetically they were actually healthier and stronger. Because they were utterly ruthless in culling out the defective. Any baby born with obvious physical defects was immediately killed. Others will killed off if and when they showed any signs of trouble. For problems that aren't outwardly obvious at any point, like hemophilia, they devised tests like cutting up the feet with obsidian - no aid was administered to the cut feet, they were left to heal up naturally, or for the hemophiliaic to bleed out and die. Turns out if you are prepared to be so vicious in eliminating the genetic defects from an inbred population, those who are left are healthier and stronger in every way. Not many cultures would accept such brutality against infants and children, but for those that do...

      In a certain sense, what our host suggests, editing the DNA of a fetus, is that really any different? The baby that was meant to be born by the natural combination of the DNA is "killed". Indeed, in the case of DNA editing, effectively a "new" baby replaces the old one. It's almost like the old European folklore about changelings, except *we* are the changelings ourselves!
      Sure, our methods might seem more humane, scientific, and enlightened, but bear in a mind that whatever practice you think is so humane and enlightened today, people a thousand years in the future will probably deem barbaric. Perhaps the better way to consider the matter is that we are doing the best we can with the means available to us at the moment.
      At the same time Christian missionaries in mesoamerica were trying to stop human sacrifice, in Europe there was still on-going Inquisitions, witch trials, and trial by combat. Were Christians really so much more enlightened, or just doing the best they could according to their understanding of the world around them? It's not a simple question.
      I'm not here to be a cultural relativist - certain practices are indeed quite horrific regardless, especially the harming of babies and young children, but the point remains that whatever you deem barbaric from the past, it is worth keeping in mind that future generations will find something you do or believe to be barbaric. Such is the nature of human progress.

    Baltar -"Adama, wait! You must hear me out. I have been to the Cylon seat of power. It is in chaos! Cylon forces are scattered throughout the star system searching for you. The route back into the Cylon empire is BARELY defended. They're spread so thin, ONE SINGLE BATTLESTAR can take control of the empire and bring it to its knees!!"
    I agree with Baltar, feign a retreat, then counter attack is the best model for success.

      Assuming you have a head start anyway, staying in the galactic plane makes it easier to find red dwarfs/nebula to use for harvesting and/or hidden direction changes. You could go ahead and leave the galactic plane early, but you'd be giving up a lot of resources and oppurtunities to make strong burns hidden by stars. You'd still get those oppurtunities if you left the galactic plane, just not as many, not as often, and a sufficiently capable pursuer would have a smaller list of stars that might be your destination.

    I was a very good math student right up until 11th grade and then I was completely derailed. I attended a Catholic elementary school before starting at the Bronx High School of Science. Like most incoming 9th graders, I had taken algebra in 8th grade. But for some accreditation reason having to do with my 8th grade math teacher, I was not allowed to take the NYS Algebra Regents Exam. So I had to repeat Algebra in 9th grade. But it felt like I was a year behind. I finished with a 96 average in Algebra and a 98 average in Geometry. I decided to apply to the Honors 11th Grade Math class because it was a combination of Trigonometry and Precalculus. If I did well, I could have taken AP calculus in 12th grade. I didn't do well. As I said I was a very good math student, but that class was full of actual geniuses. It moved way to fast for me. I had a 70 average in my first semester. I switched to the regular trig class, but the honors class had done mostly precalculus first, meaning I was a semester behind. It ruined my life in that I majored in history and went to law school. But that experience wasn't really the fault of any of my math teachers. Even with my 8th grade math teacher that was really the school's fault, not hers.
    My younger sister is an engineer, so if I have a math question, I ask her. But she had some bad math teachers. One was so bad every student in her differential equations class failed. Every student. That was quite a curve. The problem was that the professor didn't really speak English. They all had to retake it with a different professor. I don't think my sister will be sending any email thank yous to the first guy.

    The newest Alastair Reynolds book, Inhibitor Phase, set in the same universe as the Revelation Space series, has a lot of discussion about "stealth" in space within realistic physics. I haven't finished reading it yet but so far it is very good
    At one point they do exactly what you suggest, plumeting into the photosphere of a star and maneuvering using plasma fluid dynamic interactions to avoid giving up their position when slowing down into a system.

    So when I first watched this video I realized it's sort of describing the deadly snail question on a cosmic scale.
    Usually it goes like, you get 10 million dollars but there's this snail that is after you that you can't touch or you die. The snail always knows where you are and is indestructible or something. In the cosmic case you're a gigantic spacefaring civilization and the snail is a hostile alien civilization.

    • @josephfilm73
      @josephfilm73 2 года назад

      AFter 10% the speed of light you'd start running into relativistic effects. In truth, even that speed would be problematic due to energy use, and radiation at the front of the hull, both of which are showstopper problems. Unless you are Q, it isn't happening. Mirrors. Man. Big Mirrors. Bring the universe to your couch lol.

  • @389293912
    @389293912 2 года назад +2

    Using sails might be detectable by the background star field occlusion they may cause. Depends how big it is. Also you can use gravity to change your trajectory with no possible detection without any engine burn by cruising close to stars. Calculating survival distance is left as an exercise for the reader. Why travel to the rim? Just vector your fleet perpendicular to the galactic plane to avoid passing through solar systems of questionable danger. Asking volunteers for splinter missions would probably be fruitful for those who tire of the regimentation of the main fleet.

    Off topic but Issacs intercept dynamics calculations remind me that time travel scenarios are also spatial travel scenarios.

    I have to agree that very little innovation is made during "chaos". I think of the attack on Pearl Harbor. No great inventions were created during the 3-hour attack. However, if you believe in the adage that "necessity is the mother of invention", then it follows that once the chaos has passed and a group of people have managed to secure their immediate safety, then innovation and adaptation are probably the rule. Life is resilient and as such, humans have historically risen to the occasion when the time factor is removed. Thanks for the reminder on how to calculate where the trains would meet between Chicago and New York. I forgot about 50 years ago how to calculate that one.
