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