And for the sed-level stelr civilization,

That's a Dyson sphere,

for the use of civilization itself,

Say slowly:

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

In theory,

sed-level civilization,

the transparent wooden rimless smart gsses,

The Dyson sphere is simply,

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

However, the teological level needs to be suffitly developed,

There is a good measure of,

This also means,

Eveire civilizations live in a Dyson sphere,

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

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

A Dyson sphere will pletely enclose a

is able to exploit the energy in its star system,

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

Dyson spheres are theoretically possible,

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

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

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

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

If a ic civilization successfully trol the Dyson sphere,

The sed level is the stelr civilization,

For example, the eeology,

including the energy of other ps, and even stars,
