      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.

      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 ปีที่แล้ว +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.

      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.

    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.

    I like the idea to dump mass behind you. It might scatter the emission of your thrusters and at the same time can be used to accelerate towardsyour prosecutors by the same means to accelerate you away from them. For example you drop mirrors and beam lasers at them.
    This gives you thrust and also sends high velocity projectiles towards your prosecutors, kinda like a mine field.

    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.

    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.

    So glad I remembered and came back to this channel, playing stellaris inspired me lol.
    I had 2 things I'd love to hear your take on sometime. First is what you think ships would look like given different tech levels, for example your ship design given star trek tech, or mass effect level, or just post FTL in general.
    Second is an idea I got from an event in stellaris. What do you think of the idea that while a species could meet a less advanced species, but still be destroyed because the less advanced explored ideas that the more advanced never thought of. For an extreme example, maybe the more advanced had no concept of war, so just had no defenses.
    I know these are broad, but I'd love to hear your thoughts on them some time. Anyway I'm glad to be back and see you're still making amazing content.

    Is light losing energy every time it passes through or around a galaxy because of the escape velocity of each galaxy? If so can that account for part of the red/blue shift we see in the cosmos?

    • @isaacarthurSFIA
      @isaacarthurSFIA  2 ปีที่แล้ว +4

      Yes it does redshift passing out of as galaxy but also blue shifts passing toward it, so the net effect is minimal when calculated out, and not enough to account for the overall redshift of everything. It was one of the common early explanation attempts though, especially in the early days when we had giant margin of error bars on every galaxy's distance besides our very nearest neighbors.

    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.

    Oddly, Fred Saberhagen comes to mind when you speak of fleeing and pursuit not battlestar galactica. Also the primary thought when nihilist, or conquering is mentioned in terms of galactic invasion.
    I could see humanity fleeing the after effects of their own creation in pursuit of expansion more than strange invaders. Perhaps the reason why we're currently tucked away on a tiny blue speck in the outback of the galaxy arm we're located in? And, nearly every surviving tradition of tribal people says we're brought here fleeing destruction of a war that destroyed planets? Wondered if you knew that... it's a fact. "Came here on seven silver canoes when the fire people made war, destroyed our old home...", is origin story of my people.
    Berserkers, the ultimate automated hounds. "What T and I Did" reverberating in my memory fourty years after reading it. Not all humanity, but unfortunate other trait of those seeking wealth and status above others, is destruction and conquering void of consideration for humanity.
    They are, right now, currently in the process of building Berserkers, including some that can mask as humanoid, with biological synthetics improving as a matter of fact.

    • @isaacarthurSFIA
      @isaacarthurSFIA  2 ปีที่แล้ว +5

      Well they are shown moving FTL so that's presumably the method, plus inside your own supercluster the expansion rate isn't really the biggest factor in comparison to just having a speed high enough to get you there before any target galaxy has had time to evolve from bacteria to galactic empire during the time since you left :) Of course it's 40k so it's not really holding scientific accuracy up as a main objective of the stories.

      Would "zero +/- 10%" qualify as "almost zero"? And do you have any sources backing you up on that?

    I would think that the best strategy for this would be to trick the pursuers into overshooting. 1. Travel far enough away from the enemy's core space that the region is largely unexplored and impractical for them to stick around for any length of time. 2. find a star system where it would be possible for your civilization to survive in some way that is low profile, ideally a habitable planet or at least planetoids, moons, and asteroid belts that could sustain your population without too much obvious sign of industry. 3. put together some sort of "lander" craft, separate from your larger ship, capable of holding and maintaining the population long enough for them to get their act together. 4. Plot a path through that system in which the major portion of the fleet does an acceleration burn, while the smaller portion is ejected, in a way that is meant to appear to be rubble or just part of the fuel being burnt off. 5. The main fleet continues on to the next system, and so on, on a pre-determined path that will take thousands of years to complete. Meanwhile, the actual population hides out in that system in the deepest cover they can manage. 5. The enemy intercept fleet should pass through, hopefully find no signs of occupation, and quickly head out after the core fleet ASAP, meanwhile, it's far enough away from the enemy's core that it wouldn't be worth them sending any additional forces to that area any time soon. Ideally, the decoy route would take a slight angle as well, so that any follow-up intercept fleets would gain advantage from taking an alternate route that would not send them through this refuge system.
    It'd be a gamble, but better than nothing.

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.
