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