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