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