interesting comments about marerials. Funny how nobody ever thinks abotu where is all that material going to come from. can we even imagine how many planets would be totally consumed encasing an entire solar system???? Millions? trillions?
and how long would it take? centuries? millenia? Is there any affirmation that any civilization, consuming so much resources in order to construct such a thing lasting long enough to complete the task?
and for what? It would be far more cost effective for a civilization to colonize other worlds in order to spread, than pulverizing them in order to build this thing.
Yes, such a construct would defy common sense, if a civilization could build something like that they could certainly harness energies we couldn’t even comprehend.
Harnessing a star’s output is a rather modest proposal, it would be unneccessary for them.
I don’t even see how a Dyson sphere or a ringworld construct would in any way be preferrable to multiple, large, cylindrical colonies placed at strategic points throughout various star systems..
