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