    I love that the balloons are far too small. Like they didn’t understand the elements and buoyancy well enough to know the balloons have to be much larger. Not like we have negative mass particles.

            Well, air weighs a little bit more than 1 kilogram per cubic meter, and those balloons look a little bit smaller than a cubic meter

              What about hydrogen plasma as hot as the surface of the sun, contained in a weightless force field? The 'balloon is simply a decorative wrapper? Remember, it’s the future year 2025!

                Unless there’s force coming from somewhere other than buoyancy, you can’t get better than than 1.29 kg per cubic meter of lift in air at stp.

      I’m pretty sure scientists back then could have told you that these balloons are too small. The person(s) who drew that picture most likely wasn’t a scientist, which is why it looks how it looks.

      Obviously they were assuming balloons were filled with supervacuum. We have had 100 years and not invented even that.

      Truly we have failed our ancestors.

      Well, I guess they figured it’d take another 100 years to calculate that correctly, so they just winged it for the picture.
