 Freeman Dyson's Optimism

Brand: I was looking at your 1988 book, Infinite in All Directions, and remembering what it was that excited me about it. Ten years ago, most people I knew were in the depths of a kind of bad mood, harboring a pessimistic feeling that things were going to keep getting worse for the rest of their lives. But your book had this pragmatic and also rather cosmic optimism about it; it came as a complete counter to the cultural flow at that point. Did you perceive that at the time? Dyson: Oh yes. I...

 Matrioshka Brains

Matrioshka Brains (MB)1 are megascale computers constructed out of microelectronic and/or nanoscale components.  MB may be constructed as shells around a star (internally powered Matrioshka Brains: IPMB) or may be constructed independently of a star if large amounts of power are harvested from stars in other locations and beamed to the MB (externally powered Matrioshka Brains: EPMB).  A third variant, (self-powered Matrioshka Brains: SPMB) which generates power via controlled n...

 Life Can Go On for Billions of Years

I believe that life can go on forever. It takes a million years to evolve a new species, ten million for a new genus, one hundred million for a class, a billion for a phylum—and that's usually as far as your imagination goes. In a billion years, it seems, intelligent life might be as different from humans as humans are from insects. But what would happen in another ten billion years? It's utterly impossible to conceive of ourselves changing as drastically as that, over and over again. All y...

 Dyson Spheres

The mathematician Freeman Dyson, of the Institute for Advanced Study, offers a scheme in which the planet Jupiter is broken down piece by piece, transported to the distance of the Earth from the Sun, and reconstructed into a spherical shell – a swarm of individual fragments revolving about the Sun. The advantage of Dyson's proposal is that all of the sunlight now wasted by not falling upon an inhabited planet could then be gainfully employed; and a population greatly in excess of that which...
