Will We Ever Utilize Dyson Spheres?

what does $${\Delta}x{\Delta}{\rho}{\geq}\frac{\hbar}{2}$$ have to do with $$F=ma$$?

"The more precisely the POSITION is determined, the less precisely the MOMENTUM is known".

What a novel and disturbing concept!
The fact is, there are definite practical limitations to the effects of uncertainty. It's essentially non-existent on a macroscopic scale.
Unless I missed something along the line, no one has said that Dyson spheres are impossible. The question is in whether or not they would be practical. If, for instance, we would have to gather material from another stellar system we'd might as well just move there.

The point of them would be living space and/or gathering all the output of a single star. The material to build a suprastellar shell, at least a lot of them around a star, might have to come from other star systems. However, by building them you get millions to billions of times the living space of Earth. How many star systems would one have to move humans to in order to equal that? A lot of teraforming would be involved with moving to billions of systems. There probably aren't Earths ready "made" in every system! Let's say we found another Earth nearby though. It would have life of its own(I'd have to in order to fit the name of Earth) We could take the planet for ourselves; but unless we have to take the planet though, wouldn't it be better to preserve it as a Galactic Park?
