The point of using primordial black hole is that it can be very small (in the range of centimiters for its Schwarzshild radius). You can then calculate safe distance from the black hole where the gravitation and gradient generates acceptable forces for your structure. This is of course much more than the centimiters given but still very small compared to astronomical distances you would need to encircle entire Sun.
Another point of using black hole is that you decide its output (by deciding how much matter falls in) which greatly helps building dyson sphere. You can't modify Sun output.
- jychang 6y agoThe schwarzchild radius doesn’t really matter for engineering purposes. Think about the earth; when you are standing on the surface, 1 radius away from the center of mass, you experience 1g of acceleration. Imagine how much more force you experience if you were closer to the center of mass, and replaced that mass with a black hole. It’s hard enough to build a dyson sphere at 1*earth radius, the amount of forces acting on the structure at 50km radius is insane.
