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