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