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