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