really? someone’s been reading too many bad scifi novels....just try to contemplate the amount of resources needed to make something like this...you’re talking about hundreds of entire planets, assuming each planet has the right material.
any culture with the technology to do this would have the intelligence not to waste it’s resources doing this when there are better, cheaper ways.
and yes, i’ve read ‘ringworld’. cute story, but how many solar system must be destroyed just to make it?
I haven’t read the “ringworld” and haven’t really done a calculation, but it seems very unintuitive that building a ring around the Sun would take materials worth of hundreds of planets.
Do you have some calculations handy?
I do admit that I have read bad sci-fi novels.
Larry Niven's "Ringworld" won the 1971 Nebula Award for Best Novel, the 1971 Hugo Award for Best Novel, and the 1971 Locus Award for Best Novel.
We might not understand aliens' motives for constructing megastructures, and we certainly don't understand the technology that would make it possible. However, we do know that smart cultures sometimes do very stupid things.
