Have you done the calculation how much material is required for such an endeavor? I bet there are more cost effective approaches.
"The plans for demolition have been available on Alpha Centauri which is only 4 light years away you know."
It's a tiny fraction of what's required for a proper Dyson sphere. And we know civilizations can afford those because we can no longer see their stars.
For anyone who's hung up on saving nickle, we could do a low budget Worldring² or even thriftier Shadow Squares®.
²Nivenlarry ®Larry NivenThat's a giant claim you just made like it's fact.
Dyson Spheres would be really obvious, emitting infrared radiation unlike normal stars.
You are correct. That is absolutely a thing I did.
Also correct. Even past that, we haven't been mass-cataloging stars long enough for a Dyson sphere to be constructed and remove a star from our view.
One man's poison is the same man's alcohol and mankind revolves around that.
It looks promising; I'll check it out. Appreciate the recommendation.
The infrared star stands out because it is different than normal stars.
These are really good points. I figured the flaw in my theory is we haven't had precision observation long enough for DS to get constructed. Also that if we noticed the disappearance of a star, that we'd attribute it to a DS and not some natural occluding object.
