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

And for the sed-level stelr civilization,

is able to exploit the energy in its star system,

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

including the energy of other ps, and even stars,

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

sed-level civilization,

the transparent wooden rimless smart gsses,

There is a good measure of,

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

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

In theory,

However, the teological level needs to be suffitly developed,

for the use of civilization itself,

That's a Dyson sphere,

This also means,

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

Eveire civilizations live in a Dyson sphere,

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

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

For example, the eeology,

If a ic civilization successfully trol the Dyson sphere,

Dyson spheres are theoretically possible,

The sed level is the stelr civilization,

A Dyson sphere will pletely enclose a

The Dyson sphere is simply,

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

Say slowly:
