EARTH WITHOUT SUN 

We all know that, without Sun life is not possible on Earth. What will happen if the Sun suddenly disappears? In practical there is no chance for it. Suppose if Sun disappears what will happen? Let's see about it. 

SUN DISAPPEARED AFTER A WEEK:

One pleasant morning you are getting up with the Sun. But actually it disappears. In Earth sun disappears 8 minutes later. Because, light takes 8 minutes to reach Earth from Sun. After 8 minutes, The entire world will turn into Dark. The other side of Earth it becomes complete Dark and many Galaxies and Stars are easily visible to them. The Moon also disappears. In North, Aurora Borealis will happen. These are all normal changes. Let's see about the harmful changes. The major causes are, Photosynthesis will completely Stopped. This will happen in  Plants and also in Cyanobacterium. If Photosynthesis stops, Oxygen is not exhale by Plants. Suppose, This continues for an Hour, All Humans will panic Because, Continuous Darkness. Power Stations and Communication will completely shutdowns.

The Earth's temperature also decreases. In the another side, people gets up and sleep and repeats until they see the date and time. They were panicked about the disappearance of Sun. After 24 hours, World will go into massive Power cut. The Earth's average temperature will reduce to 5-7°C. Due to this, many organisms including Plants will die. After a week, The average temperature of Earth will reduce by -17°C. In this temperature, Earth looks like an Giant Ice ball. The animals in the Hot Zone, will completely die. The ocean surface becomes freeze and ocean organisms except the deep sea animals will die. But in Tectonic Fault, are warm. This place are also called as Geothermal Plates. The Scientists finally conclude that Sun will not return. 

SUN WILL NOT RETURN:

After a month, The average temperature of Earth will reduce by -30°C. Earth will become an Ice Glacier. Except Conifer Plant, al plants die. Except the peoples in the Geothermal Places, all will die. After a Year, Earth will cover with thick Ice Glacier. All Organisms completely die. In this extreme cold temperature, some Humans will live, they belongs to the Geothermal Place. Earth will look like a Giant White Ball. The Gravitational Force of Sun also disappears. Planets moves in a Random direction and motion. No Planets and no Asteroids will stable. Earth may hits to a Planet or it Enters into a Black Hole. But Earth escapes all from it, It searches a new Planet and joins into Stellar System. Earth will revolve around a New Star System. 

THE CONCLUSION:

  Nothing is Permanent.
