## Resource

Rotating space habitats known as O’Neill Cylinders propose a radical alternative to colonizing hostile planets like Mars or the Moon. By using rotation to generate Artificial Gravity, these massive orbital structures could support entire ecosystems, cities, and millions of inhabitants while protecting them from cosmic radiation and the dangers of microgravity. Powered by constant solar energy and built using asteroid-mined resources, these engineered worlds may eventually allow humanity to move beyond natural planets and become a civilization capable of constructing fully artificial Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
