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