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