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