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