So-Called ‘Dyson Spheres’ Key to Discovering Alien Life

For centuries civilization has looked to the skies in search of answers, in search of extraterrestrial life. It wasn’t until the sixties when Freeman Dyson, arguably one of the smartest men alive in the twentieth century, predicted that eventually all civilizations would outgrow their demand for energy and have to seek alternative energy sources. The Dyson Sphere was a theoretical concept for intercepting and collecting all of the energy that was creating by the sun. The ‘shells’ would orbit the planet and would be able to supply the planet with the energy it required. In theory, Dyson’s Spheres would work and make it possible for the planet to continue to evolve.

In September this year, Jason Wright, along with a team of astronomers, began their search for Dyson Spheres. The idea is, if you are looking for advanced forms of life within the galaxy, you should be looking for Dyson Sphere’s. The expedition has been funded by Templeton Foundation, who are particularly interested in the bigger answers.

If there were a Dyson Sphere system out there in one of the galaxies, the hypothesis is that it would be detected by re-radiation of energy. Something that would be able to be detectable by the amount of infra-red radiation. The team won’t be looking for a solid structure, a large sphere, instead what they propose would be the most likely of scenarios, a ‘swarm of sphere’s’ surrounding a planet or star system.

While to the average person, the idea of searching for alien life forms on a theory might seem preposterous, in fact the search for alien life itself might seem so fantastical that many people would laugh it off. Search for alien life has always been speculative, and until there is tangible proof, it will always remain that way. There is a rich history of human life looking for life in the stars.

There was some success in the eighties when a team of scientists did a sweep of the galaxy in search of large re-radiation points by using an infra-red camera. There were many spots where the re-radiation was large enough to warrant further investigation.
