I think there should be some more options for habitable areas. Smaller zero-G modules or larger (and more heavily shielded) habitable rings are good places to start.

Probably, we could use something, like magnetic boots to walk on any magnetic surface directly.

Side question. How come the technology used in Star Trek for sustaining artificial gravity was never used for propulsion purposes? Manipulation of gravity seems like the main theme for space travel. Seems to me that if you can create positive gravity, then reversing it could be used for hovering, maneuvering?

The most weird thing in movies is that if even ship is so damaged that it is ready to break into pieces, artificial gravity is still working

The Star Trek: The Next Generation Technical Manual explains that, the artificial gravity generators have spinning superconducting magnets inside them and even if you cut all power it still takes hours for them to slow down on their own and stop generating gravity.

The crew of a starship is free to move about their ship without the problems of weightlessness because of a network of small generators working together to provide the proper sense of "down".

The gravity field itself is created by a controlled stream of gravitons, using the same principles as the ship's tractor beams.

Power is channeled into a hollow cylinder of anicium titanide 454, where a superconducting rotor of thoronium arkenide is suspended in a pressurized chrylon gas.

Once set into motion, the rotor generates a graviton field gentle enough to simulate the gravitational pull of a standard Class M planet.

Requiring only occasional energy, the rotor can continue to provide an attraction field for up to 4 hours after a power loss.

I'm curious what's happen if you go outside the ship under its "bottom" side?

Are there will be gravitational repulsion, or those generators creates gravitational attraction in all directions?

I have never understood things like ability to fall through the floor into space (like in "Aliens").

The basic idea is it creates a single direction gravity well across the ship. If a hole opened up and you fell in you would exit the 1 directional field and your velocity would be preserved so you would continue to "fall".

Yes, this is simply impossible. "Force lines" of gravity field can't suddenly end up, they must be closed on some source. This is like creating a magnet with cut force lines.

Those gravity pods basically set themselves up as the local gravity well. An object in motion will continue in motion, according to Sir Issac, so given the dripping acid blood, it would commence to orbit the ship after it left the artificial gravity field.
