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