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