What would happen to us if the sun collapsed one day?

Question

What would happen to people and the Earth if the sun collapsed, not exploded at some point in the near future? What would happen to the Sun and everything around it; would that be destroyed? Would the Sun become a black hole? Because the Earth orbits around the Sun because of the Sun's gravity drawing it in, would the Earth fly off on a tangent into outer space? How would people die: cold, lack of light for photosynthesis/no food, disintegration of atmosphere, etc? How long would it take for people to die?

Answer 1

we would die in s few hour

Answer 2

The sun wouldn't become a black hole, because it's not massive enough. It would actually be about 8 minutes before we felt anything: that's the amount of time it takes light to travel between sun and earth, and nothing can travel faster then light. If the sun just disappeared, the loss of gravity would cause Earth to just continue in a straight line out into space. However, if the sun collapsed but still contained all it's mass it probably would have pretty much the same gravitational effect, so we'd continue orbiting as usual.
We'd all freeze. Id think the atmosphere would still stay on earth unless a shockwave knocked it off. The atmosphere itself might freeze.
If the sun collapsed, there would probably be some major radiation that would kill us.

Answer 3

Planets is in basic terms no longer knocked approximately or destroyed, and suns won't gravitate in the direction of one yet another. the subsequent nearest celeb is 4.2 easy years away. The galaxy "collision" might double the kind of stars interior the area around us, so the closest celeb might then be 3.3 easy years away. 4.3^3 / 2 = 3.3^2 relatively, staring on the distances to the closest fifty one celeb systems, a greater determine may well be 3.5 easy-years for the closest celeb after the "collision". i've got have considered estimates that *perchance* 2 or 3 stars, out of the 1300 billion total in the two galaxies, might relatively collide. there's a multitude of empty area between stars. And to boot ... long until now the sunlight dies, it is going to warmth up and boil the Earth's oceans. life in the international would be impossible in decrease than a million billion years. We extra desirable start up questioning approximately what to do long until now that.

Answer 4

If the sun collapsed, there would not be any life on earth. Sunlight is vital for all living things. There would not be any heat in the earth, hence humans and other animals would die. Plants would die, as they need sunlight to create their own food. As for earth... it would be lifeless.

Answer 5

When the gravity stops the sun Will get bigger and hooter.Then the sun will get so big that the surface of the sun will touch the surface of the earth.

Answer 6

I love a nice cheery question...don't worry, the sun has enough fuel for another 5.2 billion years, if you're still around then start worrying.

Answer 7

Death of the Sun

The end of life. The end of time. The end of earth and all of its inhabitants. Sounds like something out of a science fiction or horror movie. However, all of them will one day come to pass, and they all will happen when the Sun burns itself out and no longer shines its life giving rays on our planet. In this paper, we will discuss why the Sun is going to burn itself out, when we can expect it to happen, and what will happen after this process occurs.

Since this is such a dreary and dreadful topic to cover, a little humor may be a good way to start. There is an old joke where a guy walks into an astronomy lecture and listens to a professor talking about the fate of the sun. “In a billion years” the professor says “our star, the Sun will
run out of fuel and die”. The guy raises his hand and says, “How long did you say we had?”

The professor repeats his billion-year prediction. “Whew,” says the guy, “I was getting worried.

I thought you said a million years!”

As the joke above suggests in a humorous way, it is really much ado about nothing. The death of the Sun is so far away that we should not even give it a second thought, but we do. For some unknown reason, the thought of the Sun (and ultimately the Earth) no longer existing not only frightens many of us, but also fascinates us. It makes us realize how really small and insignificant our lives are in the grand scheme of the universe, and how much little control we

have over the forces of nature and time.

The Process

Our Sun is made up of more than billions and billons of tons of matter. As a result, all of that matter produces a huge amount of gravitational force that squeezes the star more and more in-

ward. In order to combat the inward crush from the gravitational force, stars (The Sun) utilizes fusion power to hold themselves up. At the Sun’s core, where the crush is most extreme, Hydro-
gen nuclei are repeatedly pushed together and combined to form Helium. A small amount of

energy is given up in these fusion reactions. The newly formed energy flows outward toward the Sun’s surface heating the outer layers in the process and puffing the Sun up to counteract the
inward force of gravity. According to scientist, as long as the Hydrogen fusion reactions are functioning as they have in the past, the Sun is safe from gravity and can continue to serve as a source of heat and light for Earth.

Unfortunately, the hydrogen fuel of the Sun can’t last forever. All good things eventually come to an end. In approximately five billion years from now, the Hydrogen at the center of

the Sun will all be converted to Helium. At this point, the Sun will begin die. Many Astrono- mers also believe that this will also start the beginning of trouble on our planet. Without its

Hydrogen, the Sun has to find an alternate way to free up energy and combat gravity. The Helium deposits in its core can be fused into Carbon and Oxygen, but only if the conditions in

The Sun’s core become much more extreme. In order for this to happen, the Sun changes in a very radical way. The core contracts and, even more importantly, the outer layers swell. When

the Sun reaches its maturity, it will begin to bloat and swallow all the inner planets. The Earth will possibly see its demise at this point. Ironically, even if the Earth is not swallowed, the

ultra-extreme heat coming from the bloated Sun will be so intense that it will burn up and scorch whatever life might remain on our planet’s surface. Sadly, there is little we can do to
escape our doomed fate in approximately five billion years from now.


Good News – Bad News


Believe it or not, our planet existing for another five billion years is actually the good news.

The bad news is that our impending doom could be awaiting us much sooner than that time. The Sun is not constant now, and it never has been. Many believe that the Sun is in a comfortable

mid-life stage and as a result is fairly stable. But, the fact is that the Sun is slowly heating up all the time. Every ton of Hydrogen gas that gets converted into Helium forces the Sun to

contract just a small amount, and that raises its temperature in small increments. In the next 1.1 billion years, the amount of energy the Earth will get from the Sun (which is directly related to
the Sun’s temperature) will increase by almost 10%. This may not seem like a tremendous amount to the casual observer, but to a delicately balanced planet’s climate, far less than 10%
can mean the difference between life and death. When scientists examine computer models for

a future climate based upon the slow increase in the Earth’s temperature, they are very much alarmed at what may possibly happen. They view the Earth as having an Greenhouse effect
gone berserk. The polar ice caps will no longer exist, and much of the fertile land we use to produce our food will be flooded. As the Sun’s output continues to grow, so much water is
evaporated into the atmosphere that even the stratosphere gets wet. Sunlight can then break apart the water molecules allowing the Hydrogen atoms to escape into space. Bottom line – no more water equals no more life on our planet. The world as we know it will cease to exist. Not a very Sunny (pardon the pun) picture indeed!

Conclusion

As was mentioned at the beginning of this paper, this is by nature a very dismal and dreary topic to cover. Even though we will not be around to see any of this happen, it is depressing
for many to think that the Earth we have come to know and love will one day no longer be in existence. It seems unimaginable to many. The bigger question to me is that will we humans also cease to exist as a species? This is a very real possibility.

Over the past several decades, we as a world community have come to start understanding that Biospheres are delicate things. It is unfortunate that we have abused ours in many regards. Even though our possible demise is billions of years away, it is not too early for us to start thinking about a possible move in the future. In many ways, we have already started by exploring other
planets for similarities of Earth’s atmosphere. Hopefully, somewhere in the distant future, humans will evolve to such a state intellectually and technologically, that life on another planet
will be possible.
