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