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