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