Debunking Common Space Myths: A Retired Astronaut's Perspective

🚀Immediate death in space is worse than being fried to a crisp - it's freezing to death while simultaneously boiling, burning, and losing the ability to breathe.

🏋️Living on a spaceship is surprisingly lazy - you don't have to lift a finger.

👃The smell of space is like gunpowder or burnt steak, caused by trace gases and particles released from the metal surfaces of the spacecraft when exposed to the vacuum of space.

⏳Time dilation is real, but going near the speed of light is not currently possible.

🔊Sound does exist in space, but there is no medium to carry the sound waves, so it cannot be heard by humans.

Do you have to exercise constantly in space?

—No, living in space is the laziest existence imaginable, as weightlessness eliminates the need to lift a finger.

What does space smell like?

—The smell of space is often described as similar to burned steak, gunpowder, or brimstone, caused by trace chemicals being released in the vacuum of space.

Can you survive interstellar travel by freezing yourself in cryosleep?

—Cryosleep is currently only present in science fiction. Freezing the human body would lead to irreversible damage and destruction of tissues.

Does bacteria multiply faster in space?

—Microbes and bacteria do grow differently in space, but strict hygiene practices are in place on the space station to prevent excessive growth.

Can you generate gravity by spinning a spaceship?

—Spinning a spaceship can simulate gravity by creating artificial centripetal force, but controlling gravity itself is currently beyond our scientific capabilities.
