Antigravity is provided by rotating a cylinder along it's longitudinal axis. It's very simple stuff.

Not sure why we need force fields. If you meant radiation shielding, liquid hydrogren or even water is a fine radiation shield. Life evolved on earth in shallow seas before there was an ozone layer.

All of the things you mentioned are possible, but very expensive today. The reason we wouldn't live beyond earth is because people just accept that it's too hard and too magical.



Forget costs. Where are you even going to get the materials for that at scale?

Sounds good for a space ship or small space station. How do you make that work for thousands of people?


Moon is close by, has plenty of sunlight, aluminum and apparently iron ores, some water. It all is at a reasonable gravity that allows to safety operate on the surface, but cheaply launch a lot into earth orbit, even using electromagnetic catapults that don't require a propellant.

That's not antigravity, it's just Coriolis Force.


Do you mean centrifugal?


I think you are right. I actually meant "центробежная сила", but blame Google Translate [1] which translated is as Coriolis Force (english is not my first language).

I thought it is a bit weird, but then I though thata US still uses imperial units, which 100x weirder, so I didn't check further. ¯\_(ツ)_/¯
