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