the sun will become a red giant in around 3.5 billion years when its supply of Hydrogen for Nuclear Fusion is running out.

It will probably swallow up both Mercury & Venus and there is a possibility that Earth may also be vaporised.

Sorry if i am off topic

In the sun's red giant fase it's size will reach till saturns orbit, so it will swallow Mercury, Venus, Earth, Mars, Jupiter and Saturn.

It is total sci fi stuff, coz it just cannot be done. Saturn is too small ( compared to stars) to withstand this ignition, the heat will make it's atmosphere and gases instable and so it will fall apart, so no, the Saturn ignition idea is not posible.

Well thank god the Wright Brothers didn't share your views on physics....

That's true but aside from gently shedding a planetary nebula our sun won't do any of that.

no, it won't

I hope that at least in the next million years, we would have explored and established society's in space.
I don't see the point of staying on earth or fixing our sun.

ok, I ain't gonna argue with that, anyways if that doesn't happen just how long do you think Saturn will be able to withstand the ignition? Saturn doesn't have that much hidrogen as the sun to produce the fusion....... it only has a tear of it compared to the sun. I am sorry but that idea is totally Science Fiction.

Your signature is way to big.

Yeah, you are right, gonna take it off now.

You don't have to take it off, just resize it.

I wasn't trying to give you a realistic figure. Its ok man you can let it ok every things ok...........

Lol, mankind isnt gonna be in this solar system when the sun runs dry, and by then im sure we would have created an artificial sun.

Why not start working on that artificial sun now?

We are trying to create fusion now. It has not been successful more than a few micoseconds.

@#$%! I better make out my will!!!...........


Lpaiche

Making fursion is very very complicated. We can't do a satifactory fusion with our current technology but the day that humans make sucesfull fusion, many posibilities will be opened.

Won't we be all dead by then? So does it matter if the sun dies when we're dead? Just saying.

I can guarantee you in about 5 billion years, humans wont exist any more.

We already have made successful fusion with our current technology, all though the reaction is a sustained uncontrolled chain. The hope is that in the future we will be able to harness the power of fusion in a controlled environment.

Easy solution to this if we survive the 5 billion (which is doubtfull) as most species have a genetic lifespan then we would have already learned how to travel by warping space \ time by harnessing the power of gravity.. (if not already) We would go to a Star system that has no chance of ever supporing life. Transport Huge amounts of Hydrogen Fuel from new star to our old sun to keep reaction going by way of a some sort of gravity space\time transport system injecting it directly into the core of our sun therore keeping it from expanding into a red giant.. This would probaly be a never ending process much as we currently refuel our current vehicles with fossil fuels . I do not beleive this will be done for the survival of mankind as I am sure we would be spread all over the galaxy by then as we are the type of species to expand and conquer however earth and the system will be spared more so for our history, lineage and sentimental value over our home planet. This technology will probaly be feasable in 200 years or so.. if not sooner.But I do not beleive we as a species will be around too even see this. We dont even know if we are going to survive the next 10 years much less the nex 100....

In 5 billion years our species will have changed and spread out so far across the galaxy no one thing could wip us all out. In otherwords it really is not that big of problem for our species.

Errr... R.I.P our Sun.

We could always thumb a ride from our little green friends to the orion cluster... I hear there are great sea views of the nitrogen oceans there.

And what did I say in my post? When I said satisfactory fusion I meant a sucessful continuous fusion, the curret fusion that we make now is very short and only lasts a few seconds.

I don't think that we should waste our energy in trying to resolve a unsolvable problem that is 5 billion years down the line. How 'bout trying to resolve the climate problem, the overpopulation problem, the looming energy crisis first. We wont have to wait 5 billion years to notice those problems. We will feel the pinch in less than 25.

So will you, Mr. Monkey.

Somebody just saw the trailer for sunshine, a science FICTION movie.

If humans exist in 5 billion years and have not been annihilated by the crazy Koreans we will be well away from this planet. Honestly, why did a 5ft tall Korean have to get a nuclear bomb. The world should be focusing on taking away his big toy before someone gets hurt. If we can survive World War III{Watch out for China, the invasion has begun} we will be fine. Scientists already have an understanding of how to manipulate space time so someone can travel light years in a second without actually moving. They somehow move the time behind them which sounds confusing but it can be done using exotic material.

I think it's not smart to critisize the koreans and chinese in this thread. That just me anyways.

Are you completely out of your mind? I have never heard anything stupider for us to be worrying about...for about 5 billion reasons. First and foremost, population. We are running out of room. And it is time to move already. That might make the unavoidable tragedy of our far, far, far, far, far distant future kind of a pointless concern

What climate problem are you talking about?

Looming energy crisis? You mean like the one experienced in the later 1970s...which actually wasn't? Less than 25 years?

Something smells like Al Gore got to you...

Nope, something from me infected Al Gore ... I was one of the co-founders of the green party.

If we solve the problems of today, it will inevitably lead to solving this problem in the future. That is a long time away, and a millenium from now (if humans are still alive) we will have technology that our little minds can't even imagine. We could gain the ability of space travel and transport the entire human race away from the earth and colonize on other planets.

stupider?

Oh...OK.

That explains it sufficiently...

you have got to be kidding me... in 5 billion years our minds will be so advanced we can control objects without effort..evolution is constant, the bigger the brain the smarter and ours is gonna keep on growing..

not to mention all the other disasters that are close to happening now, lets worry about those, not 5 billion years from now when we are all supermen

Got this from Wikipedia.


Sounds to me that we just have to figure out a way to create oxygen, (If we don't already) and we have to dig down deep enough and start a civilization underground.

MOLE PEOPLE i tell ya! MOLE PEOPLE! i'm not in my right mind now. but thanks for the info

I can't believe people spend their time worrying about stuff like this. We really are a society consumed by fear.

I know. We'll be dead by the time our sun dies. I mean what's the point?

There would be a point if we had the knowledge how to fix it and the means to do so. But we don't and probably never will.

we are worried for our grandsons x 100000 and our achievements.

Correct its a rather lofty boast to want to "fix" the sun.

I can't believe this thread is even being discussed - hasn't anyone noticed the blindingly obvious?? We've evolved from bacteria in the last few million years - in x billion years humankind simply won't exist. We'll be as different to how we are now as we are to bacteria. And before someone pipes up with "humans are the ultimate goal of evolution", don't bother, because we're not. Read what Sir Martin Rees (possibly the cleverist person alive) has to say on the subject.

This is quite possibly the worst thought-through thread I've ever seen. Utter utter rubbish.

Evolved from bacteria? ... I wash my hands of all of you then LOL!!

*snigger*

No silly, thats like saying we evolved from monkeys, you sound like an ignorant creationist/evolutionist (no offense, you probably aren't one). If you believe in all that, then it should be "We've evolved from a common ancestor between man and bacteria eons ago (anyones guess)". And if you "believe" the "common consesus" in the scientific community and pull it back further, then we are all the result of a quantum fart (our common ancestor ) , resulting in the big bang and the universe. So you see, we are just quantum farts, floating around in time... Well thats if you want to believe in that naturalistic only horsesh*t.


Agreed, but is has gone on for 7 pages so far... worst still is im helping it going on to 8 .

The only thing we can do is eke out and existence on this planet and help it exist for as long as possible.

To this end, I propose that we cull all people over the age of 65.

We can then have 'funbusses' to pick them up in designated areas (preferably of pale skin). We can then transport them to the North Pole where they can help shield the polar ice caps and prevent further melting. They can act as an insulating jacket (much like you get on a boiler).

I've spoken to some environmentalists and geologists that say that this idea has legs (unlike some of the potential protagonists).

They can also provide food for the dwindling walrus and polar bear populations.

I have discussed this on other forums including the BBC's own religious boards and they have all returned favourable responses overall. Unfortunately there were few over-65's within the demographic of the board to see how they felt about sacrificing themselves now for the ultimate good of the planet.

Bus companies and cafe's have said that their trade will dwindle to zero but surely the overall survival of the human race (even for a short time longer), must raise this as a potential consideration.

The only unfortunate outcome would be the elderly eventually becoming a fossil fuel in the future, thus rendering all of this work obsolete.

Thoughts?
