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