Do two opposing centripetal forces still cancel each other out in space? [closed]

I've conducted a test with two fans connected to each other. The top fan was setup to spin counterclockwise and the larger fan spun clockwise. In my test, it showed that once the two fans reached the same rotational speed, the beads where in a rest state (well, if it was perfectly centered and didn't have a wobble that shook the beads about) and were no longer being affected by centripetal forces. You can see my simple test here that I built in an afternoon: Opposing Centripetal Force: Two-fan TEST YouTube Video

After doing this test, I have two questions:

1. Will conducting a similar test up in space result in the same outcome?
2. In theory, is there a way to have a space station that is using centripetal force to mimic earth's gravity AND also rotating in the opposite direction at the same speed so that someone inside the space station could look out a window and objects outside the space station (earth, moon, sun, stars) would appear stationary and not rotating around the station hundreds of times per day?

The main goal here is trying to create (only in theory) a space station that has gravity simulated via centripetal force yet ALSO having it appear as if you're not rotating while inside the space station so that objects aren't moving past the window numerous times per day. Is that even remotely possible (again, only in theory and NOT actually building a real space station that does this in real life)?

• " rotating around the station hundreds of times per day?" A low Earth orbit at about 400 km has a period of about 90 minutes, that are only 16 revolutions per day.

• @Uwe, I'm not referring to orbits around the earth, I'm referring to how many times the space station would complete a full ring-rotation. In order to maintain 1G of centripetal force and the space station ring had a radius about 10,000 meters (a little over 6 miles radius) it would need to have a velocity of 700.51 mph which would be 430 revolutions per day. Smaller the diameter, more revolutions Nov 10, 2021 at 4:16
• Simply put, you seem to have a massive misconception of what constitutes "centripetal force". Please correct this deficiency, and then look at your question (and video) again. It should be enlightening. Nov 10, 2021 at 7:40
• Ah... at simple standard approach, this is a very simple "No" - not in regular conditions like occurring between "anywhere within this supercluster of galaxies" up to "anywhere within our universe". But it becomes a very, very interesting question if you take more general cosmology, e.g. the idea of a Newton's Bucket in an empty universe, and start mucking around with engineering a specific pseudo-special frame of reference instead of taking whichever the universe threw at you. Can we generate a local pseudo-special frame of reference which is spinning relative to the more global one?

• I’m voting to close this question because it just doesn't make any sense. The OP needs to understand some basic physics concepts. Nov 10, 2021 at 11:07
