Possible Worlds: The most promising ones.
Almost 500 years ago we all believed that earth was the center of the universe and for the major period of our existence we have believed that earth is unique and so is our solar system, it is very recently that we have discovered that planets actually more common than we ever thought.
Possible world is necessarily true concept if and only if it is true not only in the actual world but in all possible worlds
The Notion
We see Universe not as it is, But as it was once and existing ubiquitously.
The concept of a possible world leads to the theological problem of the existence of evil, arguing that an all-perfect God would actualize the best of all possible worlds.
It is very recently that we have discovered that planetary systems are very common across the galaxy , and many are even too bizarre to even exist .Luckily we have some promising planets for humans to Colonize and destroy too just like Earth. (sad, but True)
Before moving into that let’s peep into some factors which are considered before classifying a planet as habitable.
Goldilocks and The Bears
Remember that childhood tale of Goldilocks and the bears?, that’s exactly is the case with the planets, some are too hot, some are too cold, some has the most bizarre weather conditions.
