After 5..or maybe 15 billion years..the sun will expand..be larger in size..and the Mercury and The Venus would be roasted/boiled and the Great Earth which is inhabited by the most variety of species of life,would be the next one.Would the Earth survive..atleast a decade or so..?Our mother Earth had yet survived from being destroyed by a galactic cosmos..but has the Earth already met it?How and why did the species of Dinosaurs become extinct?Would Man be able to survive from fate?How many Big Bangs had already occured and Is there any limit?The ultimate question to add is...Did Animals come here?It can be like this that the species of mankind made a spacecraft with which they stayed at the farthest corner of the Universe and watched the Big Bang and came to the earth in the right time,then killed the dinosaurs to settle themselves?These questions wander around in the human mind(atleast mine)As we come closer to the invention of the Ultimate Universe.We'll discuss all these and related topic's here..coming back to reality..is anyone interested or do they think that we are born healthy&wealthy to die without improving the Knowledge of Mankind?

Those are a lot of questions you have there, frankly i don't know where to begin?interesting subject and one to think about for sure. |

I do like your way of thinking my friend only if more school kids were intelligent thinkers like you, don't get put off by people who are critical of you, its only because what they cannot achieve often frightens them.

Some really relevant questions that you've asked, Tapojyoti. I fear that it may ultimately prove to be the case that it won't be an expanding sun that destroys the Earth, but man himself.
I'm not superstitious, merely mildly stitious. |

What i've never really understood is why is the sun expanding?i've always held the opinion that the sun was burning itself out?

A lot of good questions here, but I disagree with the notion that no clock has the exact correct time. Time is a man-made concept, there must be at least one clock that has the correct time. How else would you know if the other clocks are accurate or not? |

if what my good friend Deluded say is true, then a stopped clock must be one of the most accurate timepieces around, since it would show the correct time twice a day

Yep..Global Warming from CFC(Chloro Fluro Carbon).CFC comes out from factories,Air Conditionars,Some Fridges,etc.Currently,"No CFC"fridge's are available.But this cfc is cutting holes through our ozone layer.Plus,WE NEED TO GROW LOTS OF TREES.The tree that delivers fresh air is...Neem.Don't know if it's available worldwide.And I'm currently afraid of the future of The Great Himalayas..Especially Mount Everest..We've to watch the Olympics..Before the Sun..There comes a galactic cosmos.It happens when a Star atleast 10 times bigger than our sun completes it's life cycle and is ready to be a black hole.It starts to decay and while it does,let's out a huge something from it's center(on both sides) and if one ray hits the Earth..Then it lost all it's atmosphere..The side where it hit would forget hosting life but the other may hold some.But then the sun's rays won't be distributed by the atmosphere resulting of life damage in one rotation.. |

@Kryptik bro, that's a good one! 
On a more serious note, I think I have to agree that Man will ultimately cause his own extinction, way before any natural calamities can. |

@deluded
Our Sun has enough fuel to last another few billion years so I don't think we need to worry about that yet - unless of course we discover the secret of immortality. (Imagine reaching your billionth birthday )
I am of the opinion that life on earth will continue long after humans have come and gone.

before a sun collapses in on it's self due to lack of fuel (burning out as you say), it's expands for several million years as the gas is no longer held so densely packed due to the sun's decreased mass compared to when it was younger. Lower mass, lower gravity, therefore less ability to hold in the remaining gas. Sun's such as ours do this, however some types of Sun's don't expand and instead just collapse without expanding. Yet others go supernova, destroying themselves completely in a dramatic explosion that takes only a only a few weeks to occur.
The giant sun however will be much less dense than the sun is now, and not as hot. Still hot enough however to fry away all earth's oceans as it expands.
By then though, my guess is Earth humans will have colonised planets orbiting other sun's. It seems quite probable to my mind that within several thousand years humans will have invented a viable form of insterstellar travel, and if so we have plenty of time to colonise our local galaxy and will no longer need earth to survive. Our home planet, and home solar system may even be abandoned well before the Sun expands to encompass the earth.

@goldenface,It's not of man's immortality..it's about mankind's stay in the earth.@all,all the burnable gases in the sun's atmosphere make helium after combusting.Like when you burn a log and when it's almost completely burnt till it is completely burnt,The flame rises higher and after it's completely burnt,a gush of flame soars up and vanishes...Scientists say that the sun will also expand..but never trust words.. |
