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