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