The answer would be the same if the sun suddenly 'went out' like a light bulb. No sunlight no food chains. No sunlight, colder. The Earth and all on it would die and become a frozen ball.
There would hardly be any light!
It is the only source of light!
According to my calculations there would be no light so the plants and animals will freeze to death.
Nothing casts a shadow on the sun. The sun is the source of light that produces illuminated and shadowed areas, and shadows always point away from the source of light that produces them.
We would be dead because we cannot survive without the sun's light and warmth for more than 8 or 9 minutes.
IT will no longer porvide light, which would make life impossible on earth
Without light from the sun, photosynthesis couldn't occur, causing plant life to die out. This would lead to a collapse in the food chain, affecting all other organisms dependent on plants for food. The Earth's temperature would also drop drastically without the sun's heat.
If the sun's nuclear reactions stopped, it would eventually cool down and no longer emit light and heat. This would have far-reaching consequences for our solar system, as all the planets rely on the sun's energy for warmth and light. Life on Earth would cease to exist without the sun's energy.
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.
The first that would happen, if the sun suddenly vanished, is that the gravitational force that keeps Earth rotating around it, would vanish with it. That would make Earth and all other planets to go in a straight line, (think of the centrifugal-force). The light, and all electromagnetic radiation (that has been threw away from the sun) will, however, still hit the Earth for about 8 more minutes, due to the speed of light and the range sun-Earth.
WE WILL DIE!! Becuase there is n light for plants to make oxygen.
The sun would win.
