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