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