sed-level civilization,

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

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

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

There is a good measure of,

The sed level is the stelr civilization,

And for the sed-level stelr civilization,

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

the transparent wooden rimless smart gsses,

That's a Dyson sphere,

A Dyson sphere will pletely enclose a

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

The Dyson sphere is simply,

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

Say slowly:

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

Dyson spheres are theoretically possible,

including the energy of other ps, and even stars,

In theory,

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

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

is able to exploit the energy in its star system,

For example, the eeology,

However, the teological level needs to be suffitly developed,

If a ic civilization successfully trol the Dyson sphere,

This also means,

Eveire civilizations live in a Dyson sphere,

for the use of civilization itself,
