Although Dyson sphere systems are theoretically possible, building a stable megastructure around the Sun is currently far beyond humanity''s engineering capacity. The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities. George Dvorsky has advocated the use of self-replicating robots to overcome this limitation in the relatively near term. Some have suggested that Dyson sphere habitats could be built around white dwarfs and even pulsars
