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