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.

This is true its on of the many ways for the sun to end... another way could be implosion and stuff... what can actually form after the supernova is a black hole white dwarf or a newtron star but i dont think our suns big enough to do that...

Did you know if our earth was to be commpresed to the point of turning into a black hole it'd be about the size of a marble (normal one that you hit with the game marbles) yeah that big lol... sad isnt it that much mass in that little thing...

well a teaspoon of a newtron star weighs like 200 thousand tons or some crazy number like that lol...

but yeah it wont happen in our life thim... by 5 million years lets hope we are off this blasted rock of a home we call...

I think this is a nice story, but it doesn't matter to us and our problems not even a little bit. It does not matter if the world ends tomorrow or in a million years. What really matters is the way you see these constant changes. Just look at yourself when you were 10 years younger - is that really you? We all change and not just every year but also every second. The world around us also changes - just look at the change of winter, spring, summer, autumn and again winter.

So we see that the world is more than just a change, it is also a constant circle! We are born, we live, we die and we are born again and so on just like the winter comes after autumn and again summer comes after spring. Night comes after day and day comes after night - it is the same with our lives (why would it be different if we are a part of this world?): we are born (day) and we die (night) but then we are born again (day)...and so on and so on!

What I am trying to say here is, that if the world ends, it will not end this constant circle - it will be just another change, but we, with all our problems, which we carry on after this human life into death (night) and again into life, will still exist and not a single one of those problems will end with the "end of the world" - we'll just have one more problem

And the solution in my opinion: Think about yourself, how certain can you be that you will survive another day in this human form??? You cannot be sure! It is also true that everything changes. It is also true that these changes bring you unhappiness, because you loose your loved ones, your loved objects, you get older and death is nearing, vacation ends, you cat dies, your favorite trip to himalaya ends, and so on...

So we should focus on how to end this unhappiness! We can only do that by realizing that these changes happen and START NOT TO EXPECT THAT THEY WON'T HAPPEN! Because that is exactly what we do and that is exactly what makes us unhappy

All our problems come from this little fact - we want things to be different than they are. If we except them - where it the problem now?

Yes, correct - there is no problem anymore and we can be happy and enjoy the moment, being greatful for everything we get!

> "Yeah, but that is difficult to achieve!"

I sure agree with that, but it is the only way we can really be happy, because problems will always be here with us! What matters is how we percieve them!

End of the sun? Does it really matter after what I've said..?

My high school teacher gave us a scientific reason about how the dinosaurs died and it all starts with an asteroid blasting itself into our atmosphere and creating a huge dust cloud all around the Earth causing 75% of all of the Earth's living creatures to die out. Not to mention aren't there ice ages coming up? The whole world would freeze up. What if global warming was just meant to happen? What if all this was the work of mother nature? We all know that as the sun gets older it gets brighter so what if by the time the 5 billion years are over, the world would be 100 see?

If the scientists are interested in leaving and saving humankind they'll have to go much further into the universe, away from our galaxy, our solar system. Or would it be as simple as facing whatever is coming?

Nice little topic there

But you said this is what will happen in 5 billion years, so really thats long enough for most people to not care, well especially me

by that time we will have been and gone and so will many of our family down the line but it would be cool if that did actually happen

I'm 100% percent sure that we won't be there to see it (I mean people in general). Space is, as you probably heard, very BIG. And humans will live somewhere else before Sun runs out. But where, we don't know yet, and we dont bother too much, since there is still a lot of time before that happens. If I could get frezed right now, and melted 5 billion years latter, I would do that.
Unfortunately, I can't

It seems to me that colonization of Venus would be a step in the wrong direction (Mars would be best if we were trying to "escape the heat" so to speak). Besides, Venus is the hottest planet in our solar system (it's dense, toxic clouds trap in heat, so it's actually hotter than Mercury). It would be much easier to colonize Mars than Venus, even if venus is about the same size as Earth.
