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