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