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