what would happen if the sun shut itself down?

Question

i no that we would die in a matter of days and we would run out of oxygen and food. but is there anything else that is importian

Answer 1

um we would die in seconds not days

Answer 2

Interestingly enough, it would take approximately 7 minutes before we would even know it! (That's how long it takes the light to reach earth from the sun)

After that, it would be down hill all the way for every living thing on earth.

If by shutting down you mean just no more light and heat - the earth would start to cool immediately - and, as you point out, all life would be gone in a very short time - perhaps two or three days at the most.

If, on the other hand, you mean it physically disappears - we would spin off into space - unfortunately, the end results as far as life on earth is concerned, is the same.

There's a good reason the ancients worshiped the sun, eh?

Answer 3

Well..The short answer is that BEFORE the Sun actually 'dies', the Sun will evolve into what is called a red giant star. Its outer edge will be way out here near the Earth's orbit so that the Earth itself will be Bar-B-Qued. This will happen in about 6 billion years, But... there are studies out that suggest that in about 500 million to 1 billion years from now, the Sun will have grown in its power output so that the temperature of the Earth's surface will be 50 - 100 degrees higher than it is today. The oceans will evaporate into the sky which will cause the earth to heat up just like Venus is today with surface temperatures above 500 degrees F . So, long before the Sun dies, life on this Earth will come to an end.But.. remember, there still is hope because it took multi-celled life about 600 million years to get to were we are today. This means that we are half way finished with the age of life on this planet. 500 million years seems like a long time, but if we take too many wrong turns in creating a future for our species, even 500 million years from now, we will be extinct a long time before that! Natural catastrophies, asteroid impacts and other things can easily cause a devastating impact on humans from which we could not easily recover space travel technology. So, in light of this(not sun light) suggest you go out there, get a nice convertible and live it up today because who knows what tomorrow will bring

Answer 4

permit's assume the gentle is only being teleported away by way of a widespread alien teleporter field someplace between the sunlight and the Earth. if so, the actual result on earth does not be very considerable. issues like seasonal modifications, eclipses, and random cloud conceal all impact the Earth's climate greater suitable than an added quarter-hour of sunlight. you will could desire to have the sunlight off for a minimum of a few hours beforehand the climate began changing plenty. If it replaced into purely quarter-hour, the psychological and social consequences (superstitious human beings going nuts and thinking this is an illustration of the top cases or however) might a great deal outweigh the meteorological consequences.

Answer 5

By the time the sun does "shut down" we'd all be dead anyways. The sun is slowly expanding with age, in 10 billion years nothing will be able to survive on earth, the only way the sun would ever shut down scietifically speaking is if it exploded which would fry us in seconds. But theoretically speaking if the sun did shut down without killing us in that process then we would die in the following days. Plants need sun to survive, we need plants to get oxygen and with the already high amounts of carbon dioxide in the air we would die even faster and fire wouldn't last either to keep us warm because they need oxygen to keep burning.

Answer 6

We would not die in seconds.

We would have to seek an alternative power supply.

Our environment would be radically different and I think we would all become depressed in the eternal night. (Except for a few night owls who stay up all night on yahoo answers!)

The world would not finish. Just solar power would finish and photosynthesis would stop so many plants would die.

However, the trouble then is the ongoing effects. Many parts of the forests and the plants turning CO2 into O2 may well die. I don't know if we would rig up huge lights to compensate or find another way to prevent our atmosphere from becoming unbreathable

but we would have days to fix it

we'd probably have to switch to nuclear power everywhere

"i no that we would die in a matter of days and we would run out of oxygen and food. but is there anything else that is importian "

LOL....You don't consider THAT as being important enough???? LMAO

Answer 8

We would have to get off the planet, a very longtime before the demise of our sun. Because, the sun would have turned into a red giant star which will engulf the earth positively killing any lifeforms on the planet. Fortunately, it won't happen for another 5,000,000,000 years. But, after that it will eventually collapse under its own gravity and create a black hole.

Answer 9

I 've watched some documentaries in Discovery Channel hosted by Sam Niel on " In space with Sam". The documentary mainly talked about the black hole, surviving on Mars, and shutdown of the Sun.
Yeap,.....that's right, you heard me, there will be one day where the Sun is going to shutdown,.... but in this case, it wasn't just the Sun itself that was going down, It's the black hole in space that's starts to consume the bits in galaxy. And there's a supermasive Black hole ( not the song by Muse you fool) that's hanging around the solar system which threatens not just the Sun but Earth and other planet.
Which by the way, 'IF ' the black hole starts to consume the mighty Sun, let's just say it'll be the start of dooms day in the whole galaxy!

Answer 10

Well, this IS like asking what would happen if fire stopped working on earth... but anyway, the earth would get extremely cold very fast. If you were deep enough underground you would have some time, but you'd eventually run out of food.

The end result, no matter what, is death.

Answer 11

All life on Earth will come to an end .The sun is the biggest benefit to man. It makes life possible. All life on Earth depends on energy from the sun.Some hot water systems depend 100% on the sun-- solar water heating.
