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