When their will be no sun we wouldn't be alive to see it let me explain:
When the Sun dies out it will trigger a massive explosion expanding 300 times it's usual diameter meaning it will consume Mercury,Venus and Even Earth (possibly even Mars!)
Even if you were further away the Sun would burn us if the core hadn't all died out if it had then we would all freeze to death.
well... the sun doesn't go down. the earth does something called rotate which creates the illusion of the sun going down. but for the sake of answering your question, if the sun never went down we would all die somehow.
If the sun never went down, that would mean the world has stopped rotating. If the Earth stopped rotating, time would be less relevant because the sun would never "move". Also, the seasons and such would probably get seriously messed up and everyone would die eventually.
Our kind of life requires warmth and energy to survive. Here in our planet, the Earth is warmed by the Sun, which provides all of our energy either directly or indirectly.
If our Sun were to fail or disappear (neither could happen), the Earth would soon freeze solid and all life would die.
But we can build our own environments and provide for our own energy. Space probes far from the Sun are powered by nuclear reactors; our own interstellar space craft will need similar power sourced.
Before our sun "stops shining," as it creates enough helium from fusion, it will swell to a Red Giant, and envelop the Earth. Then helium will start fusing into heavier elements for a hundred million years or so. Then it will start shooting out matter in destructive pulses, eventually creating a nebula. These pulses will throw whatever planets from our solar system that may have survived into a wider orbit, or out of the sun's gravity altogether to go sightseeing. But our sun will still be shining in the center of that nebula -- shining even brighter, but much smaller -- as a white dwarf. That will last about a thousand years before it cools enough to "stop shining" and wander through space as a giant black rock about the size of what was once Earth. About 100 years later, someone will post a question on Answers.com asking "Why was the Sun so important?" and some smartypants will answer "Your mom."
we will die because
1.the plants need sun to reproduce and make food
2.animals that eat plants will not survive
3.animals that eat animals that only eat grass will desapear
4.so on and so on :) :D
Temperatures will immediately drop to sub-zero temperatures and everybody will freeze on the outisde. The inside will still be working and will take a long time to freeze or die out. This is proven by scientists who have thrown themselves into liquid nitrogen trying to entirely freeze themselves so they could get thawed out in many years time. Unfortunately it doesn't work so they died.
The earth would be too cold to live on, and plants would not grow, meaning no food.
If there was no sun, there would not be a Solar System, which means no Earth, no Mars, no comets, no nothing.
we would not know about the solar systems
Dead.
We would not exist. Our sun is a star.
life will cease to exist. no human or animal will have the energy to forage for food and will die.
Then life on earth would be cold and everything else will be cold. No one would exist. But it would not happen if god had the power to keep it warm. The sun would never do this because it's body has stuff that is hot!
the planets would not receive heat from the sun and all life on earth would cease to exist. also the planets would not rotate or be held in place. the sun is what holds the planets together in orbit.
nothing would happen, the sun is constantly going through nuclear reactions
If there was no sun, then life wouldn't exist oarth
We would not exist. Our sun is a star.
If our sun did not exist the other stars would be little different from the way they are. The sun is just one of billions of stars in the galaxy. Many of the stars we see in the sky are larger than our own sun.
The reaction in the sun which gives us energy involves helium. If helium didn't exist we would receive no energy and life wouldn't exist on the earth.
life will cease to exist. no human or animal will have the energy to forage for food and will die.
People would navigate using celestial events like the stars or setting sun.

well thats easy, it would fly away from the sun in a straight line.
It is very unlikely to the sun will every cease to rise. It is more likely that the sun would first cease to exist, most likely by exploding into a supernova. This would kill all of Earth's inhabitants.
If the sun where to abruptly cease to exist, after 8 minutes, the planets orbiting it would careen off into space. This would be due to the sudden ceaseation of the effect of the sun's gravity, which can only travel at the speed of light.
It is, if one side were to continuously face the sun, though, life would cease to exist. The side facing the sun would become extremely hot while the side facing away would freeze.
Nothing would happen.
