Study Notes
- The idea that you will immediately fry to a crisp by unfiltered solar radiation in space is untrue; in reality, you will freeze, boil, burn, and suffocate.
- Living on a spaceship is weightless and lazy, but astronauts must exercise two hours a day to maintain bone density and muscle strength.
- Space has a lingering smell that is a trace of off-gassing chemicals and particles from the metal of the spaceship walls.
- Einstein's theory of relativity means that time passes differently for an astronaut in space traveling at the speed of light compared to people on earth.
- Explosions in space create sound, but there is no way for the sound to travel in the vacuum of space.
- We currently do not know how to control gravity, so the only way to simulate gravity is by spinning a spaceship.
- Warp speed, cryosleep, and growing taller permanently in space are all science fiction myths.
- Bacteria does grow differently in space, but the International Space Station is kept clean and hygienic to prevent any harm.
- The gaps between bones in the body can expand temporarily in weightlessness, making astronauts slightly taller, but this is not permanent.
- Astronauts must plan ahead for the slightly taller and stretched bodies by fitting their spacesuits and crash seats accordingly.
