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