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