    Ruri is basically in charge of things back home. The empire of might is the main muscle while the villagers have the experience of living there to manage things.

    I love the faith in modern orbital engineering here (space agencies WISH they could have orbits last millennia), but the ISS's orbit decays about 100 meters per day due to upper atmosphere drag and gravitational pull. They have to do an orbital adjustment about once a month. Plus, the ISS was already shown crashing in Dr Stone, in one of the 'what Senku's dad and friends did' montages in season one. (I know this for certain because the image of Byakuya standing on the headland where his fellow astronauts' graves were, watching the pieces of it burn up in the atmosphere, that hit me like a freight train and I ugly-cried for a very long time.)
    It's very doubtful anything human-made of significant size is left in orbit, since it all requires similar minor, regular orbital adjustments to keep it up there. Plus there's the length of time involved here. Even if it's a metre every year, that's 3700 missed adjustments, so it will have deorbited ages ago.
    Same with orbital flotsam and jetsam. Each launch into orbit mission adds about 20-30 bits and pieces to the junk cloud, which is currently about 25000 pieces larger than 10 cm and countless smaller bits. These deorbit in a period of years to centuries depending on orbital height. Even the highest orbiting debris will have had 37 centuries to fall, and so won't likely be a factor anymore.
    That said, I don't doubt Senku and co will be getting back into orbit at some point. It's just unless Why-Man and co or whoever else might be awake and functioning have been doing launches in the interim, there won't be much in the way of human-generated objects up there.

      I understand for LEO, but would the same hold for geostationary orbit objects? Sure, they would be out of orbit, but not necessarily decayed unless they really got kicked in a major way.

      @@HaganeNoGijutsushi Geostationary orbits also require station-keeping adjustments to remain stable. Gravity from the Earth and moon, solar winds, etc all effect them as well. When the thruster fuel for adjustments runs out they are toast, and I very much doubt any satellite put into orbit has enough fuel to last 3.7 millennia.
      There's a very slim chance they would have had an autonymous end-of-life program that boosted the dying satelliite into a higher orbit, but in that case it's still going to be beyond Senku and co as reaching anything higher than LEO is going to take a very long time.

    Thinking back if Senku’s father was able to preserve music with make shift cement
    Maybe he also preserved other precious minerals or tools

    This is too far back for you guys to remember but we actually saw the space station fall back to earth
    Definitely think they'll go to space at some point i mean their flag is literally a rocket

    The scene of Ginro swimming after the boat, after being hesitant at first, is seemingly a jojo reference.
    Remember when Narancia was hesitant to go after the boss in the boat with Bruno? That's pretty much the same

    It is bad how many important people went on the boat, but if the show is gonna focus on the boat then it makes sense from entertainment purposes.

    I do want to point out with titanium being found only as an oxide, pretty much any metal only exists in nature as an oxide. Except for highly inert metals like gold any metal left in nature will react with the surroundings and form an oxide. That is what an ore is, a rock which has that metal as a core part of the compound, not a raw metal. Every metal then needs a unique refinement process to undo the oxidation and recover pure metal, and this can very wildly between metals like iron just needs a furnace with carbon to burn it but aluminium is really difficult and needs a lot of electricity. So to refine titanium you just need to find a deposit of ore in’s the same way they found their other metal deposits and then run through the refinement process unique to titanium. Though I have no idea how difficult that is and might be completely inaccessible to these guys anyway but for different reasons than it is only found as an oxide.

    Ryusui is greedy, he accepts it, the detail with Ryusui's greed is that he turned a defect into a perk. He does whatever and his best to get what he wants, he rather risk it all before giving up on something, he understands that if there's no risk, there's no gain either.

      The point isn’t that platinum is rarer than titanium it’s that the show has not revealed why they are interested in the pod and you are just telling them.
