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