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