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