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