Still thinking outside the box...
You can create artificial gravity by use of centrifugal force
Is it possible to increase the gravity of the planet by adding that force to??
Actually, your first line "outside the box" should clue you in on Centrifugal Force.
Artificial gravity through centrifugal force only works if you're inside the object that is spinning.
The basic experiment, filling a bucket half way with water then spinning around with the bucket, you notice the water stays inside the
bucket....because it's on the inside. Turn the bucket around and the water will go flying out.
If you've ever watched any movies showing a space station that spins for gravity, you'll get the idea. The movie 2001: A Space Odyssey
very good example of that. People are walking around the inner surface of the giant wheel that is spinning. If you were on the outside of the ring, it
would want to fling you off.
If the earth were a hollow shell, then if it spins fast enough, you could get 1 G of gravity and walk around on the inner surface of the shell of the
planet, but you would only have 1 G at the equator. The further north or south you go, it would get lighter and lighter.
But again, you'd have to be on the inside of the planet's crust, walking around on the inner side.
We do not get flung off our world by centrifugal force because one, the Earth isn't spinning that fast, and two, the gravity of our planet is more
than enough to hold us to it.
Even if you could increase the Earth's spin, the amount of mass our planet has is more than enough to hold on to us and everything else on the
The only thing you would achieve would be to make our day / night cycle shorter, make some very powerful winds, and tidal waves.
The only way to increase a planet's gravity is if you could increase it's mass.
