I have a theoretical question. I have been reading on what would happen if the earth suddenly stopped rotating around its axis, and I have learned that would result in the annihilation of all life on the planet. I also learned that the earth rotates currently at 465 meters/second.
Now, my question. What is the optimal deceleration factor that would allow the earth to stop over time (and not suddenly), while allowing live to continue? How do I build a machine to slow down the earth to a complete stop, without destroying all life on planet?
