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

And for the sed-level stelr civilization,

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

The Dyson sphere is simply,

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

This also means,

If a ic civilization successfully trol the Dyson sphere,

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

A Dyson sphere will pletely enclose a

For example, the eeology,

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

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

is able to exploit the energy in its star system,

Say slowly:

That's a Dyson sphere,

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

In theory,

The sed level is the stelr civilization,

However, the teological level needs to be suffitly developed,

for the use of civilization itself,

the transparent wooden rimless smart gsses,

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

including the energy of other ps, and even stars,

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

There is a good measure of,

Eveire civilizations live in a Dyson sphere,

sed-level civilization,

Dyson spheres are theoretically possible,
