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