Re: About planetary gravity
And anyone who's ever ridden on a merry-go-round or other spinny-type ride knows that the rotation tries to throw you OFF of it not pull you more into it. If Earth's spin were to have any real impact on us it'd be more likely to throw us into space than it would to pulls us into it. Thankfully, gravity is stronger than centripetal force.
Just because it's futuristic doesn't mean it's practical.
