    If we managed to make baloons holding vacuum instead of needing expensive/explosive hydrogen or helium would blimps make a comeback?

    Hydrogen and helium work literally 95% as well as vaccuum would without having to create a balloon made out of a physically impossible material
    This question could easily have been googled, which is what I did and am summarizing for you. Youre welcome.

    Thats been long debunked.
    Supply chain issues =/= running out of helium
    Regardless, vaccuum balloons are not an alternative, as they physically cannot exist.

    Vaccum weighs less than helium or hydrogen, dumbass.

    Your balloon would need to be made of diamond.

    Balloons can already hold vacuum. You can vacuum the air right the fuck out of a balloon. And it won't float because it isn't buoyant.

    Honestly, retarded as this thread is, now I am kind of curious. Can you actually design a vacuum vessle that is light enough to actually achieve lift off?
    It should be possible in theory...

    Just fuse hydrogen. It's not rocket surgery.

    They can, it's just classified.

    Tell me anon, which is greater? 13.5 or INIFNITY (Assuming structural elements can be ignored :^)

    It's easy we just need a material that is half the density of diamond while having 50% greater stiffness

    Infinity minus 1 will always float higher.
