What Happnes if Sun Exploded? ???

What would happen if Sun exploded? 

That star at the very center of our solar system.

That super hot ball of plasma that gives us heat and energy and amazing complexions and all the life we have on earth that is all because we are luckily positioned at an ideal habitable distance from the sun. Sun is the core to our lives and existence of humanity in this universe.

Well, that very golden ball is a just waiting to explode one day. The sun is about 4.6 billion years old and it is only expected to last about another five billion years. After that sun would expand to become red giant and then it will be shrinked to become a white dwarf and then a black dwarf or a dead star. Surely, we would be long gone before all that happens. But can you imagine how it would be to watch sun explodes before your very eyes? How it would look like? Just like a magnificant firework that a world will see? But in reality we wouldn't see anything.

As we know of sun, it is one hundred and fifty million kilometers away from us and it takes eight minutes for sunlight to reach us. Yes, it may seem super faraway, in the supernova terms we don't stand a chance. For earth to be completely safe from supernova, our earth needs to be fifty to one hundred light years away. 

But the good news is that, If sun explodes tomorrow, the resulting shockwaves wouldn't be strong enough to destroy the whole earth, they will only damage the sun facing part of the earth as it will instantly boil away.  The remaining part and people on it would face scorching temperature fifteen times harder than sun's current surface temperature. And there will be complete darkness since sun has just exploded. And without sun and its mass keeping us in orbit, the earth would drift away into voids of space. Earth would just start floating into the darks of space while its remaining inhabitants desperately struggling to stay alive. Also, there are chances, that floating earth would locks into orbits of some other sun like star which might provide same heat, light, and energy as our sun but unfortunately by that time we would be all long gone.

So if we knew in advance the day sun would explode. We would still need thousands of years to prepare to survive the exploding of sun. Humanity can survive it by getting into huge fortified bunkers underground. As within one week after the explosion of sun, the temperature of earth surface would drop into -18⁰degrees. And within a year after, the temperature would drop to -73⁰degrees and this point the oceans will start freezing from top to down. Within one thousand years the earth's atmosphere would freeze and collapse leaving anything left on earth exposed to cosmic radiations and meteor impacts. Hopefully by that time we would found ourselves a new home.

The good news is that, if sun is to die, it wouldn't happen overnight that is actually an arduous and slow process taking place over billions of years. The sun would get brighter and it would start to expand. During this process it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way as violent birth of the big bang that created earth. Who knows a new life could form? can you imagine a new earth and new humanoid species? Well it is hard to predict how our galaxy would look after billions of years from now. It is especially hard to imagine our solar system without the golden anchor that keeps us all together but yeah one day in the very very distant future the sun would expand and then it would shrink maybe leaving a room for a new star to take its place. And if by some miracle humanity still exists to that point, where it may live ? maybe on some space station? 

Summung up, Sun is not going to explode over night it will take a gigantic chunks of time to happen and by that time the humanity hopefully have made its inroads to other earthlike planets into some other galaxies. Thus, these are the possibilities if sun explodes overnight. So if you want to learn more epic scientific exploration possibilities then stay in touch with What Happens.
