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