A "Dyson Sphere" is a purely hypothetical object for the straightforward reason that it refers to a structure built to encompass an entire star in order to capture as much of its radiation as possible. Freeman Dyson, an actual physicist, didn't invent the concept named after him but he did seriously think that as the energy requirements of a technically advanced civilization grew, it would perforce be obliged to this expedient. He thought that it would be a good signature to look for when searching for alien civilizations. In other words, a Dyson Sphere is an extrapolation of "the march of progress" to an absurd degree.

And yes, I realize that you probably meant to refer to R. Buckminster Fuller. But you gave me an excuse ... :-)
