Concept of universe
Just as an egg has a development phase, similarly our universe also has a development phase.
Like the different body parts which are developed in the egg of the chicken, similarly different solar systems are being developed in our universe.
If we take our sun as a part to describe in an egg i guess it would be the part of a cell like nucleus.
Just as when the cell is ready to hatch the matter enclosed comes out, similarly our universe also exploded which the scientists call as big bang theory and out we came as a part of the chicken ie developed solar system.
The chicken on the whole doesn’t have life; it is the compiled effect of the live cells i.e. solar system that gives the outward look as if the chicken or the universe of having life.
And as the chicken grows up to be a hen or cock, similarly there would be a phase in the universe when the universe would give a youth appeal, i.e. the universe would be radiating with its stars and other heavenly bodies emitting the most bright colors effect.
And as the youth comes so will the old age follow, and collapsing of the universe would initiate.
Finally the decomposition of the chicken and the disintegration of the universe would take place and the life element in the universe would be totally eliminated as its cells solar system would gradually be destroyed.
So in short the general idea of the concept of universe can be visualized with the concept of an egg.
The quantum and the relativity theory are the main theories used to describe the universe.
The cycle of birth and death is everywhere!
Every sun in this universe act as the power source in this universe like mitochondria in a cell so the solar systems can be referred to as a cell and sun will eventually die and hence the cell will too..
But as there is no rebirth, it seems that the universe will become a mass without life.. But till now it is supporting life and in near future, someone may find that we are a part of this living thing as presently we humans don't know where we stand in this universe whose extent we can't even imagine.
We are a drop in the universe and the universe is a drop in other universes. But if you don’t have that drop there is nothing. It is part of the whole and whole of the part concept. Life like humans can be present anywhere in the universe. It is the race to capture the best habitats in the universe, the race which we are not even aware of. As the death of our abode will near we will be a part of this race and come to terms with other people who have reached at a very advance sage in the race. Slow evolution and non creative thinking are the main reasons why we still have not even come to terms with this fact.
