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