Are Dyson Sphere's Realistic? [Analysis]

a reply to: amazing

Why are we talking about one thing. I am talking about what scientists are talking about. Which would be to start with a band of satellites. It doesn't need to block out the sun either. Just to make in unatural. Like it couldn't be a comet swarm.

The analogy that a civilization will not create a Dyson Sphere for they will have ships with reactors zipping where ever they want is short sighted. It is similar to state why would a city make a sky scraper when they will have trains and cars and can go make another settlement.
Sure they will, but the city will still grow and their need for power.


The argument that a civilization will never need that much power is again short sighted. Mabey they will found a solar system to harvest it's sun to use in some exotic way such as augment or manipulate forces of a small black hole to bend some ripple in space and in this senecio, this certain sun may be their only source of energy that can attempt such a feat.
This is just meant to describe some far off high energy requirement technology, not for an exact match, but to make an argument that we cannot foresee the energy needs of such an advance civilization, but if their anything like ours, as they continue to push the boundaries of what is possible, they will eventually have to harvest a whole sun.


Any arguments on different facts such as it will be impossible to make is as well short sighted. Any of those points can be solved by any creative mechanic/engineer.
