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