An utterly emormous construction on an unthinkable
scale. A mere
theory, a Dyson
Sphere is a "space ship" that encircles
an entire star
, so as to harvest ALL of its energy. To make
Sphere would provide an unimaginable
amount of living space and energy.
A lot of debates have been
started over the size of a Dyson
Sphere, but for a small(ish) star
the diameter would have to be close to 200,000,000 km. Even
though many people
whether there is even
enough matter to MAKE
Sphere, almost everyone
agrees that if a civilization were to have the ABILITY to make
one, they wouldn't even
have a use for a Dyson
Sphere, as by that point they probably would have had something better.
Sphere for the solar
system would be about 600 million times the surface area of the Earth.
A much debated
sizes of Dyson spheres can be from 190000000 km to several light months (for more than one star inside of the sphere).
"originally proposed in 1959 by the astronomer Freeman Dyson as a way for an advanced civilization to utilise all of the energy radiated by their
sun. It is an artificial sphere the size of an planetary
orbit." -Anders Sandberg
