As we know that world population is increasing day by day and it's going to 10 billion and at one day the population will exceeds and earth will no longer to fulfil the demand of human beings
So how the human will fulfil their energy needs?
Now what is Dyson sphere?
Dyson sphere is a theoretical concept basically in this concept a star is enclosed in a very large sphere and the energy of star is harvested and then can be used.
These mega structures are theoretically possible but in reality, these megastructures are beyond the range of human engineering capacity.
In fiction the Dyson sphere Is defined as the hollow sphere around the star but according to research it is mechanically impossible to surround a star with a sphere
Instead of this Dyson suggested some ways to form a Dyson sphere around a star.
Dyson swarm: Before we know about swarm, we need to know about Dyson ring basically it is a ring around the star in an elliptical manner and when number of these rings will combine and become a Dyson swarm but there is a disadvantage in this pattern is that this is very complex
Dyson Bubble: This is also similar to that of Dyson swarm but unlike the Dyson swarm but they are in the non-orbital manner means that they are in the vertical form and these would be totally stationary around the star
Dyson shell: This variant is most used in fictional stories as it is like a shell and covers the whole star the energy harvested would be much more as compared to the other two spheres
But such a shell does not have gravitation interaction with the star which will result in the Collison of the star with that sphere.
From the above note it is cleared that only an advanced civilization can construct a Dyson sphere so scientists at NASA are searching for an intelligent civilization by noticing the flaucation of stars in the night sky if the star flucates to much means that a Dyson sphere is constructed over it.
Freeman J. Dyson in 1960 was the first person to discover this concept all the theories we have read above was proposed by the Dyson.
If something like this is constructed in next few thousands the energy or fuel will no longer be a problem for human beings as star will have enough energy to feed the entire population for thousands of years.
