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