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