In theory,

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

For example, the eeology,

That's a Dyson sphere,

The sed level is the stelr civilization,

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

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

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

A Dyson sphere will pletely enclose a

However, the teological level needs to be suffitly developed,

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

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

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

Say slowly:

There is a good measure of,

sed-level civilization,

is able to exploit the energy in its star system,

The Dyson sphere is simply,

including the energy of other ps, and even stars,

for the use of civilization itself,

Dyson spheres are theoretically possible,

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,

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

And for the sed-level stelr civilization,

This also means,

the transparent wooden rimless smart gsses,

Eveire civilizations live in a Dyson sphere,
