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