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