Yeah i know what a structure is. What i mean is how does this megastructure look? Is it like a dyson sphere or a giant tube. And how big is this megastructure? Some accounts say it is the largest but didn't tell the specific size.
"In Greg Egan's Diaspora, the manufactured objects at the end of the characters' journey are inconceivably vast in terms of our universe. Each sub-atomic particle contains an entire universe, each sub-atomic particle of which contains an entire universe, then iterate millions of times until you get to our universe.
Nothing else in SF comes within trillions of orders of magnitude of being as large." -end
That will be $9.78, please. Sorry, no personal checks.
