There is a good measure of,

A Dyson sphere will pletely enclose a

is able to exploit the energy in its star system,

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,

And for the sed-level stelr civilization,

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

If a ic civilization successfully trol the Dyson sphere,

The Dyson sphere is simply,

For example, the eeology,

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

the transparent wooden rimless smart gsses,

for the use of civilization itself,

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

The sed level is the stelr civilization,

In theory,

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

This also means,

That's a Dyson sphere,

Say slowly:

Eveire civilizations live in a Dyson sphere,

Dyson spheres are theoretically possible,

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

sed-level civilization,

However, the teological level needs to be suffitly developed,

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

including the energy of other ps, and even stars,

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