What if the sun disappears one fine day ?
igor_vitrenko [27]

Explanation:

Here is an assumption what would happen if sun disappear for one day only, it would be more curt if it disappear forever but from POV of one day below are certain consequences of such a situation over solar system,

  1. You might be thinking if sun disappear then we would be seeing the moon for a whole day but don't forget, moon don't have it's own light, it reflects the rays coming from sun if sun disappear then surely moon would be like a ball kept in dark.
  2. It would happen for the first time if an asian man calls to someone in Europe, usually when here is night there is day and vica versa, but this time both will have same appear (night only)
  3. There's a idiom in Indian Hindi language that says "seeing the stars during the day time" which we use when we are going through something worse that we see the stars during daytime, but this time every human being on earth will see the stars during daytime, do not forget stars have their own light, they are not sun dependent.
  4. For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.
  5. Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.
  6. people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.
  7. Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.
  8. Our ozon layer will have it's first leave from his duty.
