what is the fate of sun and our earth?

Question

We all know that the final fate of our sun as a star is a white dwarf for ever. The fate of sun can be summerised as followings a) Hydrogen burning phase - 10.6 Gyr , b) First Red giant phase -1.3 Gyr, Helium burning phase 100 Myr, d) Se cond Red giant phase 20 Myr e) Unstable pulsation Phase 4000,000Yrs F) Planetary nebulae phase 10,000yrs and g) White dwarf lastly for ever. We are in Hydrogen burning phase of our sun. What is not konwn very well what will happen to this earth in First Re d giant starphase. Will the sun engulf its all planetary system as it will expand. How long this earth will be habbitable for men? 500 million years mor What will happen to this earth as the temperature will fall down? Ice cold age will reappear/

Answer 1

Fate of our sun as you have put it is very acceptable.but Laplace believed in theory of determinism but uncertainty Principal gave blow to it. so it very certain we can predict future only certain extent. Our projection into future is based on our theories & observation. (any theory which proved today may changed by one single observation of tommow so theries are also not constant) to be very sure of what happens after 5billion years is probbaly any bodies guess Your data are good methmetical calculation. tommarrow there may be new theries which may give altogher new picture
If things are destined to happen the way you have put it then is wiser for mankind to search better star's planet & go there. but I am very sad for this kind of approch & one more possibility is man kind creat such technology which may change fate of our sun also.
I think we should be very optimistic about of future Nothing is impossible

Answer 2

I think that in 5 billion years from now, we'll have figured out a way to move the Earth into a more distant orbit as the sun goes supergiant. Or maybe a sunshade of sorts. These are just engineering problems. Maybe move Mars too while were at it. Of course, Titan and Europa will be inhabitable waterworlds... but the giant phase wont last long. I think that, for sentimental reasons, we will move good old Earth and find a new, younger sun for her, or re-fuel Sol.

Answer 3

I believe it is currently theorized that Mercury and Venus will be consumed but Earth will be spared that ignominy. Regardless, it will not be much more than a cinder. Subsequent to that, the Sun will become a white dwarf. It does not have nearly enough mass to go supernova.

This won't happen for billions of years though. Humans will be long gone before that evolutionarily speaking.

Eventually though, both the Sun, the Earth and everything else in the Universe will blink out of existence as all the protons complete decay in about 10^40 years.

By the way, good sirs, I visited your website. It seems to be a charade of science cloaked in metaphysics as exhibited by the page headed by: "DO U Think UNIVERSE has a creator or GOD exist? Where He then steps in? He must be a bigger structure then universe. What is His dimension?"

What business is it of any science to ponder the metaphysical? Complete poppycock! And work on your grammar. It is appalling.

Answer 4

i trust that in 5 billion years from now, we would have discovered a call to move the Earth proper right into a extra a recommendations-off orbit because the daylight is going supergiant. Or will be a sunshade of kinds. those are in simple terms engineering themes. perhaps move Mars too at the same time as were at it. Of route, Titan and Europa will be inhabitable waterworlds... notwithstanding the large section wont very last lengthy. I evaluate that, for sentimental aspects, we will be in a position to move reliable historic Earth and locate a clean, youthful image voltaic for her, or re-gas Sol.

Answer 5

During the helium burning stage, the sun will swell, engulfing Mercury thru Mars. This won't happen for about five billion years though. I'm sure that by then, men will have inhabited planets elsewhere. I must have hope. Maybe Jesus will come back before then!
When the sun burns all the helium, it will collapse, either into a white dwarf, or a black hole, or it will go supernova!

Answer 6

Case 1.

We are moving towards the sun inch by inch each year or so. At certain stage we will be at a point of no return. This may happen before any other event that you have mentioned. This is a certainty.

Case 2.

There are many large stars that are in the unknown orbits at the present, far far away, one of them may get close enough to our sun or our earth. You guessed it. This is a possibility.

Ice age happens slow enough, so we may go under ground, or be able to evolve enough to survive and or adopt to the conditions. Same with warming.

Answer 7

Earth will be habitable till sun reaches its red giant phase , which is much more than 500 million years expected by you, it is roughly 450 crore year i.e 4500 million years away. But, the big question is that whether we human being 'll allow it to last long, thanks to pullution and nuclear threats! If every thing goes well till 4500 m years, the sun'll become roughly 50 times its present size and the heat will vapourise the three inner planets. Unfortunately we are one of them!

Answer 8

all those who claim to know about the fate of earth and sun are comparing them with other stars and planets..........but i think our case is a bit different simply because we humans live on earth..............even today man has technology to track and destroy meteoroids and asteroids coming our way............so who knows we may by that time be enough evolved genetically or scientifically to prevent our sun and earth from having same fate as other stars and planets..................after all some one has said "life survives on hope"

Answer 9

my theory is that the sun will be come a red gaint, engulf mercury, venus, its goin to burn out it helium then boom super nova but that my theory just sayin that what i said in the 7th grade along time ago n the 1st person above is wrong because it engulf the earth 2 guy duh or it blow it out

Answer 10

The earth will be destroyed and the sun too probly.
