A Dyson sphere is a hypothesized artificial habitat built around a star by a civilization with sufficient technology. It is intended to capture as much as possible of the power output of the star, and should be a distinctive characteristic of a civilization able to control the resources of a planetary system.14-May-2009
What does a Dyson sphere do?
What’s the point of a Dyson sphere?
A Dyson sphere is a truly mammoth mechanism, big enough to surround an entire star. The purpose of this megastructure is to absorb the energy released by a star, for use by humans, be it on Earth or elsewhere.
What can we do with a Dyson sphere?
Think of a Dyson sphere as a huge, energy-catching ball built around a star. It seizes solar energy and converts it into the kinds of energy that we can use to power vehicles, computers or whatever other advanced, power-sucking technologies we manage to develop in the next couple of million years.
Is a Dyson sphere realistic?
A Dyson sphere, as proposed by the physicist Freeman Dyson in 1960, describes an immense artificial construct – or a series thereof – orbiting a star, with the capability to capture its light and convert it to useful forms of energy. … The most realistic and feasible variant of the Dyson sphere is called the Dyson swarm.
How far away would a Dyson sphere be?
93 million miles A Dyson sphere might be, say, the size of Earth's orbit around the sun. We orbit at a distance of 93 million miles (about 150 million km). The website SentientDevelopments describes the Dyson sphere this way: It would consist of a shell of solar collectors (or habitats) around the star.
Is the Death Star a Dyson sphere?
No. A Dyson sphere collects all the energy from a sun. It's inside diameter is roughly the orbital diameter of a habitable planet and the population live on the inside surface as though it was a planet surface. The Death Star is the size of a small moon.
Would a Dyson sphere melt?
But after absorbing and exploiting the solar energy, the structure would eventually have to reradiate the energy or else it would build up, causing the sphere to eventually melt, according to Dyson.
Could you live on a Dyson sphere?
You would never, ever run out of liveable space in a Dyson sphere. We're talking several billion times the inhabitable surface area of Earth. You'd also be capturing the entire output of the local star for use, making power essentially an unlimited resource with no environmental downside.
Can humans build a Dyson sphere?
Feasibility. Although such megastructures are theoretically possible, building a stable Dyson sphere system is currently far beyond humanity's engineering capacity. The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities.
