  • Our future in the galaxy is typically envisioned as tied to the stars, be it on planets orbiting them or vast megastructures fueled by the alien suns, and yet the true future of humanity might be to dwell in the vast gulfs between the stars or even in a galaxy in which those stars have ceased to exist.

    There was a story in Analog quite a while back about a civilization in the Ort cloud that ran a high-energy-use society by living one day and then hibernating for years while automatic mechanisms collected energy and matter. Multiple colonies had agreed to live in-synchrony, so even a multi-year low-energy transit between far distant colonies would effectively happen "overnight".

    This episode reminded me a lot of Sid Meier's Alpha Centauri expansion with the Nautilus Pirates. By starting out in the void of the ocean away from everyone else, you started with an immense area to expand and it was much harder for potential enemies to even get to you. Most times you would be such a massive empire by the time first contact was made that you could steam roll over any other civilization. I see Exo-Stellar Civilizations with a similar potential.

End game power plant would be an artificial black hole, with vanilla solar panels to start. But the key is to make it not "map" size limited, but limited by only how much ram your PC has like in modded versions of Factorio (and that is quite a struggle and takes years just to use up 16GB). One cylinder done = time to build another as a trade outpost.

      Bouncing is a liberal word. Isaac's scenario sounds like there's nowhere left to go by the time he thinks this is worthwhile. I do wonder how densly populated interstellar space could be. I imagine a brownian jiggle of drifting habitats. Interesting scenario to create cultures in and contrast them with your typical belter folk. I'm picturing a ringworld feel of radically hetrogenous people all scanning for resources while hiding from pirates.

  • @UNSCrearadmiral
    @UNSCrearadmiral 3 года назад +2

    Quick question...
    For an sci-Fi planetary defense, it more power efficient to use something like a rail gun or a mass driver over a large Laser? I’m in an arguement with a friend, I’m in the camp for a mass driver however he’s all about DEWs.
    I know both should be more effective as an orbital platform rather than a ground side installation, which is where we are basing our argument off of.
    A mass driver (as so far as I understand it) is limited by travel time primarily however the larger the mass you are accelerating the more power you need. And your effective range would be largely based up computational limits, but would be easy to dodge at ranges where it could take up to a minute or more for your projectile to arrive on target. A Laser or similar energy weapon would not have this issue, but as so far as I understand lasers, the farther out you have to reach, the power requirement starts growing exponentially, although I could very well be wrong on that.

    • @Leo-ip3yx
      @Leo-ip3yx 3 года назад +1

      Pretty impossible. Illusory walls would easily discovered by any civilization like ours because of our powerful telescopes. Illusory walls wouldn't be able to replicate fake planets around all the fake stars (light dimming) and gas composition, infared, etc all at once for all the stars we can observe that with telescopes like Hubble. Its just too much to fake let alone construct. They'd also have to create illusory gravitational lensing and a ton of other things.
      Much less effort to annihilate the civilization or just do nothing because they wouldn't be able to lift a finger even if a early space civilization like ours discovered some super mega civilization is literally harvesting whole stars.

Have we considered that some of these civilizations, when they reach a certain level of knowledge and wisdom, choose not to go the eternal growth route of building bigger and bigger hives and exploiting more and more natural resources at the planet-wide and system-wide scales? What about low industrial footprint civilizations, which still develop and use advanced technology, but have strict population controls, smart resource stewardship, an ecological mindset and a desire to maximize the comfort of the relatively few individuals living in them? I would think that given large spans of time, many of the few civilizations that actually survive would have chosen this route rather than incessantly trying to jump up the Kardashev scale.

That is an unstated assumption of the Kardashev scale and I think of much of what Arthur talks about when he discusses advanced civilizations and what they're likely to look like . I don't think it takes a great deal of social and political evolution beyond where we are right now to envision a society that limits population growth for sustainability and efficiency reasons, and does it in a humane and fair way. Hell, China did it by passing one law. (I am not advocating or supporting China's one-child policy, just pointing out that it CAN be done through simple means.) How about a highly advanced civilization of only 1 million members in an ecologically smart, low industrial footprint world that has chosen not to reproduce like bacteria and instead maximizes the quality of life for each individual, but doesn't generate an enormous technological signature that we can see?

    17:50 Tricky part of fusion for us is largely keeping the plasma hot, something which space would help it two fold just off the top of my head making it so easy a baby could do it in space. First and foremost here on Earth we must contend with Atmosphere, Gravity, and Electromagnetic fields of our environment. This makes preventing the Plasma from touching the side cost considerably more than it would need to on Earth as the near perfect vacuum would be created in Space with almost Zero energy cost on our part. Further more the larger we make fusion reactors the easier it is to hit the break even point hence the reason we just keep going bigger here on Earth and in 30 years will reach break even point ;) . In space, when our Reactor could literally be made the size of a small astroid if we wished something as Basic as a Fusor design for Fusion would be more than enough to rapidly reach break even as the Time periods for Ions and Electrons to get from one grid to the other means we could run them in a Pulse mode such that packets bounce back and forth far easier. We would likely even be able to make it multiple layers of Grids in the Future timing them in such a way that the packet automatically avoids the inner grid through electrostatic repulsion( the number one damper in small fusors) . It would be simple, You Have the Grid charged with a Negative charge so it attracts the Positive Deuterium and just as the packets are passing through the grid you shut it down for brief instance then reverse charge such that it now uses repulsive forces to push towards another inner grid gaining power from the positive and negative electrodes. It Literally would be a small sun just sitting there in space producing materials and energy for us all the time.

    An interesting prospect in the local group intergalactic environment is the prospects of reaching Andromeda which is approaching the Milky Way as the galactic corona's of both galaxies are intersecting its low density but it offers a slower approach to getting to our nearest major galactic neighbor. There is also a higher density pit stop around a million light years out halfway between the giant spiral galaxies where the two coronal halos intersect compressing material and driving the beginnings of the star formation of Milkomeda. It is of course pretty far out and limited in terms of what is there now as we are only in the very early stages of the Merger but for an exostellar civilization it might very well be prime real estate You could not only offer boosts to colonists on their way to Andromeda but you also can be pretty sure you don't have any annoying neighbors to deal with.

    I don't know why but I feel like dark energy and dark matter might be a way to get a space craft close to the speed of light, or even FTL, If in the future we discover a way of using dark energy to power an engine that could collect dark matter while you travel to be used as your propellent, the faster you go, the more dark energy and dark matter you would collect and as it is spread evenly throughout the universe, I feel like this type of engine could reach light speed or even go faster than light, as long as you could keep getting more and more dark energy and dark matter as you go faster, it's kind of like having infinite energy and infinite propellent, that's saying if you could some how survive reaching these speeds without killing the crew or destroying the ship by hitting a dust particle, far as I know though, there might be a cap on the speed you could push the dark matter out the back of the engine

    The calculations for collecting interstellar medium assume that relative speed of the collectors are are small, but if you shoot a high speed spaceship in the direction of a molecular cloud you can trade your velocity for collected material, and use higher density of the medium for a shorter deceleration path and smaller sizes for deceleration devices (the collector).

    5:30 The size of a ship or habitat might be estimated by the thickness of shielding it needs. I'd say this might be even 100 m or more depending on speed and radiation strength. So supposing the shielding might be just 1% of the diameter easily diameters of 10km are reached. So anything from oil tankers to sky scrapers might not be considered as it does not even meet shielding needs.
