what happens when the sun goes to die? 

 Our light sources. The energy which presents all over the earth is the gift of it. we all live because of the light.
Research says that it emits 3.86* 1026 watt of energy. Out of them, only 1.74 *1017 watt energy strikes on earth. But how much energy we use out of them?  
Every day we use a thousand units of energy. In electric equipment, mechanical equipment, civil equipment, etc…
But we know the importance of energy? Important of the sun?
Water cycle on earth will crash. No rain no cloud a wind curler of air all think which need of living thing will stop.  Our oxygen cycle will stop. So our oxygen reproduction will stop and what happened after that? All the earth will die.
          Now if energy sources die slowly what happens?
First darkness will rule all over the world. Then the temperature goes down and all the plants and trees have also consumed the oxygen so our oxygen will go to ends slowly. Think about it make you excited?

 Some fun also no light no weak up any work the next day? Just enjoy sleeping. Wow only sleeping. The entire student does not go to school. Not weak up in the morning.
But no light no energy and without energy what is the purpose of life because we all live indirectly energy. The entire living think need energy.
We must need another energy source to live. We understand the importance of the sun when it’s gone. Not even our earth but what all the planet can’t get the energy and lost its shining.
