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