In scifi, a lot of starships are spheres. The first person to ever have a sphere ship was probably E.E. Smith in the Skylark series (started around 1928), though he believed spaceships would have to be streamlined to get less resistance when traveling through space. In the 1920s, space was believed to be a lot “thicker” with H+ atoms (essentially, a loose proton). In reality, space only has a proton in 10^28 cubic centimeters, so streamlining in space is unnecessary. This was also why the Bussard Ramscoop, a particle collector at one point seen as the solution to the issue of energy in space travel in the 70s, was ultimately unworkable, as space is a lot “thinner” than we all thought.
The person most associated with popularizing spherical starships is Larry Niven, who made a pretty airtight argument for why spaceships would be spheres: if you remember your high school geometry, you know that a sphere is the shape with the lowest ratio of volume to minimal surface area. For this reason, hot air balloons are also spheres, to use the least amount of fabric possible. Because geometry is exactly the same all over the universe, Niven argued that any alien race we encounter would have spherical starships as well.
i can’t wait for THIS etymology lesson with the aliens
Here’s something to think about as you kick off 2025: We are all stardust. Every atom of oxygen in our lungs, of carbon in our muscles, of calcium in our bones, of iron in our blood—was created inside a star before Earth was born. Hydrogen and helium, the lightest elements, were produced in the Big Bang. Almost all of the other, heavier, elements were produced inside stars. Stars forge heavy elements by fusion in their cores. In a star of intermediate mass, these elements can mix into the star’s atmosphere and be spread into space through stellar winds.

this what im going thru rn. if anyone gaf
***factually correct version since i didnt check sources v well last time
btw the katy perry/bezos' girlfriend/other irrelevant billionaires (with the exception of amanda nguyen go research her) 10 minute space stunt was not the first all female expedition no matter how much they try to market it as such. the first all female mission was in 1963 with soviet cosmonaut Valentina Tereshkova, who was working class and had to pass incredibly hard exams to be chosen from 400 potential candidates. just in case we started falling for the propaganda machine again
Astronomers are the funniest people on earth actually
