Have you ever look at the sun. WEll maybe with sun glasses but look at it. Well this Sun is really old for stars. Yes are Sun is a star. But it is old. Really it only has 5 billions years left! Yeah might be alot for us but for stars not that long. Here is what will happen in 5 Billions of Years from now.

You always picture a perfect sun rise? In 5 Billion Years something will start to happen to that sun rise. The color of te sun will first turn from the yellow we see to a Volient Red color.

Next, the sun will start to grow. Keep growing first Mecury will be burned away from the sun. Then Venus. Then as you know Earth will be destoryed. Even before the Earth is taken over by the sun it will have no water left. Everything burned. It would be the end of Earth for ever.

Then comes Mars. Mars is taken over by the sun.

Even the giant gas giants will be sucked up. Jupitar will be destoryed and Saturn. Then the sun will let out its last blow and collaspe on its self. Then making huge dusts from where this great Solar System last was.

Nice story...
Did you make it up or found some infomation somewhere?

It seems interesting..

yep, that's the most probably scenario of how the sun's gonna end (5 billion years is enough for the human race to be wiped from earth forever, be it a self-made incident or something we can't influence...)

The scene you've described is the perfect example of what is known as a "Super Nova" in astronomical terms. That's when gaseous bodies like the sun reach their fusion limit and explode into a massive white sphere for a short duration, unleashing a huge electromagnetic storm into the surrounding galaxy.

In actuality, a Super Nova isn't the explosion of a dying star.. instead, all the while it was dying, the core of the gaseous body gradually got transformed into heavier and heavier metals and this gradually extends out to quite a big diameter - like a ball of solid metal. Once the fusion limit is reached - all the superheated gaseous molecules that had flown far off during the fusion reaction, come rushing back towards the core (as the reaction there has stopped and there's no more heat driving them outward).. an immense storm of such gaseous particle come rushing in only to be rebounded back the infinitely dense and solid core.. This rebound action spreads these particles way further than they'd travelled during the normal fusion of the core.. this outward storm is what appears as Super Nova.

The next step following this is to implode (the opposite of explode) where the whole scattered mass starts to fall back onto itself giving rise to a zone of infinite gravitational pull. For a short while the sub will exist as a body named Pulsar, which rotates just like the sun does, and keeps on emitting X-rays at regular intervals. These can be detected in far-off galaxies as of now.. the pulsating emission gives rise to the name Pulsar.

The final step after Pulsar is a singularity we commonly know as a Black Hole.

Such events are occuring at tandem given any moment of time everywhere around us and if provided with suitable equipment, none are that difficult to observer (except, of course, the highly debated existence of black holes)...

Pretty nice story. Of course, before any of this actually happened we would be dead anyway. Or so the theory is.

This is because the Sun's energy would hit the earth more powerfully than before, causing deadly radiation. There are two reasons why this may occour, one is that we have been destroying the ozone layer through pollution, so we would recieve the entire sun's energy - which causes deadly radiation. The second is that, when the sun finally burns out, it will use up its remaining energy quicker and the result would be powerful radiation.

Of course, the theories only work if you actually believe the sun will die out...

OMG, What is my grandx10^7 sons/daughter going to do about it ? I must think of a way to prevent this.. so that my future generations are secure.

The theory regarding sun will die out it true because after all, its a star. But, I think, till then, technology will be sooooooo advance that in that era, you will come back from Work and say "Honey, lets have a dinner at Saturn. Its your 2456th birthday and how can we forget that ;-)"

Humans might evolve soo much that they will have advance technology of communication and time travel(i guess). Let's leave it to our great grand children..

OpaQue, for time travel you would need to be able to travel at the speed of light. And we already know that is not possible... yet...

And has someone changed the title of this topic or something? It DEFINATELY did not have that title earlier...

lmao

hmm by then, or we destroyed ourselves, or we live on many other planets.
You know how evolution works, maybe we develop a very big skin to protect us from it all

The Sun gives and takes, I see it as a natural way of cleaning up your mess after your done

I have heard the part about the sun getting red but not expanding all the way to Jupiter. lol Would that mean that pluto will be like the Earth someday having the perfect temperature for life. Of course it wouldn't have life because it has no autmosphere or surface but it wouldn't be so cold. I heard that after the sun turned red it would go white and then just burn out. Imagine one day you woke up and the sun was dark. Complete darkness except from the stars. You would live for a while til the plants die, the trees die, and you lose all the food because animals that eat plants would die and so on. Pretty scary.
