“Earth is the cradle of humanity, but one cannot remain in the cradle forever.”
- Konstantin E. Tsiolkovsky
“As a rough approximation, let us say the Virgo Supercluster contains 10^13 stars. One estimate of the computing power extractable from a star and with an associated planet-sized computational structure, using advanced molecular nanotechnology, is 10^42 operations per second. A typical estimate of the human brain’s processing power is roughly 10^17 operations per second or less. Not much more seems to be needed to simulate the relevant parts of the environment in sufficient detail to enable the simulated minds to have experiences indistinguishable from typical current human experiences. Given these estimates, it follows that the potential for approximately 10^38 human lives is lost every century that colonization of our local supercluster is delayed; or equivalently, about 10^29 potential human lives per second”

Hope & Fiction
- SETI - Our mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations
- Planetary Society - Know the cosmos and our place within it.
- Planet Stories - A tool that lets everyone collapse and timelapse satellite images of almost anywhere in the world into stories to show change.
- On the L5 Society - links to the previous L5 mailing list by National Space Society.
- ManyWorlds.space - This site is for everyone interested in the burgeoning field of exoplanet detection and research, from the general public to scientists in the field.
- Club for the Future - This club is a way to connect young people who love our home planet, who believe in the power of human ingenuity and the abundance of space, and who are unshakably optimistic about the future.
- FQXI- Foundational Question Institute catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality, but unlikely to be supported by conventional funding sources. Especially good are the lectures.
