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