Is Anybody Out There? -- Revealed

If you're a Star Trek fan, you may recall in the series ST:The Next Generation, in the episode entitled "Relics" (First aired: 12 October 1992), the Enterprise picks up a distress call from a transport vessel that has been missing for 75 years. "As the Enterprise drops out of warp to respond to the signal, the starship is rocked violently by a massive gravitational field. Although initial scans do not find the source of the field, they trace the field to its center and discover a massive spherical structure, 200 million kilometers in diameter (or two-thirds of the Earth's orbit around the Sun). The sphere's dimensions are consistent with those of the (until then) theoretical structure known as a Dyson Sphere."1 This is the episode in which the Enterprise discovers that a pattern has been locked in the transport vessel's transporter buffer these past 75 years, and after some tinkering by the Enterprise crew, Captain Montgomery "Scotty" Scott materializes on the transporter pad.

The
Dyson Sphere is named after noted physicist Freeman Dyson, who originated the idea in 1959. Via @projectblackcat, I found a link to the Discovery Enterprise blog, which features a video of Dyson from the TED Conference -- Technology, Entertainment, Design -- held in Monterey, California, in February 2003. I'll save you the trouble of clicking on over to the DE blog and include the video below. Dyson speaks on searching for life in the outer Solar System; he is a genius, a space geek, even a comedian, as you'll see if you watch the vid, and though he rambles a bit, if you have the time (approximately 20 minutes), it is well worth the investment. More after the vid....
