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