If a cosmic civilization can successfully control the Dyson sphere,
For example, the warp engine technology,
Dyson spheres are theoretically possible,
It' s a huge building that encloses almost the entire star,
In theory,
For example, you can arbitrarily travel between the Milky Way galaxy with a diameter of about 100,000 light-years,
na looked at the transparent wooden rimless smart glasses,
Civilizations that reach this level should be able to travel easily between stars,
This also means,
for the use of civilization itself,
One possible way to harness stellar energy is the Dyson sphere,
second-level civilization,
even developed a way to travel faster than the speed of light,
The Dyson sphere is simply,
A Dyson sphere will completely enclose
That' s a Dyson sphere,
The second level is the stellar civilization,
Even entire civilizations can live in a Dyson sphere,
Then it can be said that it is already a stellar civilization,
There is a good measure of,
can utilize the full energy of the star system in which it is controlled,
is able to exploit the energy in its star system,
Dyson spheres are like huge structures made up of countless solar sails,
Harvest almost all the energy of stars with high-tech level,
Say slowly:
including the energy of other planets, and even stars,
However, the technological level needs to be sufficiently developed,
And for the second-level stellar civilization,
