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