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