Good catch! I wasn't thinking in terms of "escape velocity", I was thinking
more "if Earth stops spinning, we all fly off into space". Somewhere in
that I made the association Earth=star and people=planets, but the
translation doesn't really work, does it? D'oh on me for forgetting Physics
II and Dynamics.
I guess this is the price I pay for watching Fururama once. Never again!
