A Dyson sphere wouldn’t be much different from a big cloud of modern satellites, perhaps with bigger solar panels, but the materials would be the same.
You don’t need strong materials for a dyson sphere. You basically just put solar panels into low-orbit until you captured all of the outgoing light (or like any appreciable fraction of it, you just do it until you have the energy you need).
You might be confusing “Dyson sphere” with the Dyson shells from science fiction, which is more specific type of Dyson sphere. You don’t need “scrith” or “neutronium” to make a Dyson sphere out of satellites (a Dyson swarm) which is the more realistic type that Dyson originally proposed, or out of statites (a Dyson bubble).
Do we know of materials that could make a good dyson sphere?
