The sed level is the stelr civilization,

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

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

A Dyson sphere will pletely enclose a

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

If a ic civilization successfully trol the Dyson sphere,

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

Dyson spheres are theoretically possible,

The Dyson sphere is simply,

Eveire civilizations live in a Dyson sphere,

In theory,

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

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

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

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

for the use of civilization itself,

This also means,

Say slowly:

That's a Dyson sphere,

sed-level civilization,

There is a good measure of,

However, the teological level needs to be suffitly developed,

is able to exploit the energy in its star system,

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

the transparent wooden rimless smart gsses,

including the energy of other ps, and even stars,

For example, the eeology,

And for the sed-level stelr civilization,
