A more serious problem (with the solid version) is that no material imaginable could withstand the compressive forces involved.

- mulmen 9y agoI'm imagining a material that can withstand the compressive forces involved.
- ekianjo 9y agoDyson himself said the solid version would not work: > Dyson replied, "A solid shell or ring surrounding a star is mechanically impossible. The form of 'biosphere' which I envisaged consists of a loose collection or swarm of objects traveling on independent orbits around the star."

- taneq 9y agoScrith has enough tensile strength, so I'd imagine it could have similar compressive strength...
- SideburnsOfDoom 9y agoScrith is a fictional "unobtanium". "The tensile strength of scrith is theorized to be similar to the Strong nuclear force" which means "god-level magic involved". http://larryniven.wikia.com/wiki/Scrith http://larryniven.wikia.com/wiki/Scrith
- taneq 9y agoIt sure is imaginable, though.
- SideburnsOfDoom 9y agoThat's a low bar: we can imagine things that are impossible. We can imagine things that aren't even self-consistent.
