The theory behind it is if an advanced enough race could capture and contain a microscopic black hole then basically, you can toss any junk you happen to have and get energy for it. The reflective bubble you see around the black hole is supposed to be some sort of “anti-gravity” field that could cancel the gravitational and tidal forces of the black hole. The only problem you’d have is if the black hole happened to evaporate while in your space station. Then you could kiss the station good-bye, as well as a good deal of the planet.
I agree that the planet needs a lot of work, mainly in the part closest to the camera where it’s a bit blury. I added the clouds mainly to make the planet a bit more interesting. It’s really probably more like a moon because of the large distance between the planet and the clouds.
Thanks for all the comments. I’ll try and post an update soon.
