The Dyson sphere is simply,

In theory,

And for the sed-level stelr civilization,

is able to exploit the energy in its star system,

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

For example, the eeology,

including the energy of other ps, and even stars,

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

That's a Dyson sphere,

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

Eveire civilizations live in a Dyson sphere,

However, the teological level needs to be suffitly developed,

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

Say slowly:

the transparent wooden rimless smart gsses,

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

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

for the use of civilization itself,

sed-level civilization,

If a ic civilization successfully trol the Dyson sphere,

This also means,

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

The sed level is the stelr civilization,

Dyson spheres are theoretically possible,

A Dyson sphere will pletely enclose a

There is a good measure of,

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

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