That's a Dyson sphere,

The Dyson sphere is simply,

Civilizations that reach this level should be able to travel easily between stars,

For example, the eeology,

Then it be said that it is already a stelr civilization,

the transparent wooden rimless smart gsses,

utilize the full energy of the star system in which it is trolled,

This also means,

A Dyson sphere will pletely enclose a

Eveire civilizations live in a Dyson sphere,

The sed level is the stelr civilization,

For example, you arbitrarily travel between the Milky Way gaxy with a diameter of about 100,000 light-years,

If a ic civilization successfully trol the Dyson sphere,

Dyson spheres are theoretically possible,

for the use of civilization itself,

even developed a way to travel faster than the speed of light,

sed-level civilization,

However, the teological level needs to be suffitly developed,

including the energy of other ps, and even stars,

And for the sed-level stelr civilization,

Say slowly:

Dyson spheres are like huge structures made up of tless sor sails,

It's a huge building that encloses almost the entire star,

In theory,

One possible way to harness stelr energy is the Dyson sphere,

There is a good measure of,

is able to exploit the energy in its star system,

Harvest almost all the energy of stars with high-tech level,
