Falling objects reach a "terminal velocity", where the speed loss from air resistance matches the speed increase from gravity. This is usually around 125 mph for something with mass and air resistance of a human body. Cats top out at about 60 mph. (Please don't ask how I know this.) Nothing approaches the thousands of miles per hour needed for a stable orbit at Lunar distances. Lower orbits need higher speeds.
Sorry, that's what I meant by critical mass. Very different, I know. My point was that this creates an object with a large amount of kinetic energy. The energy could be transferred to the mirror array by either collision (preferably with a wall of force attached to the array as not to cause damage to the array itself) or some sort of net hooked up to pull the array.
Gust of Wind in airless space? I suppose it's technically legal. You'll kick it up to the wind speed generated by the spell. That's 50 mph. Not as fast as the falling cat, and not nearly enough for orbital stability.
Same argument as above. Repeat this enough times and you'll build up enough energy/speed.
And, for the record, there is gravity in space. You can counter it and get the zero-gravity thing going for you, if you can just find a way to achieve orbital velocity under D&D rules. Maybe we should work on that angle.
Well yes, technically every object in the universe is constantly gravitationally attracted to every other object. Being in some void area of space though, the numbers dwindle so much that they are negligible, much like Jupiter and I don't really feel the pulling from each other.
And you're high enough level to Levitate a mirror array the size of Delaware? Well, if you say so...
2000 lbs at level 20, and it's only a 2nd level spell. It could be cast multiple times on different parts of the station, or a higher level spell could be created that could handle more weight.
I've heard of a homebrew rule where one could apply Heighten Spell to spells without DC's to increase the effects to that of another spell of whatever level it's raised to.
One solution already proposed is the "Floating Castle" gimmick that hangs the whole thing from a permanent Force Cage. Absolutely immovable no matter how much physical force is being applied.
This exposes one of the major flaws with certain types of magic in a fantasy world. When an object is made immobile, it becomes immobile in relation to what?
The planet still rotates and moves through space at enormous speeds, meaning that an immobile object would most likely disappear as soon as it came into existence (and cause massive destruction depending on which side of the planet it was cast).
This would imply that the object is not really immobile, but inherits the same velocity as the planet (though that still doesn't account for rotation). But why that planet specifically? If it's based on the planet it was cast, then what would happen in void space?
