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