1.If the sun disappeared, for eight-and-a-half minutes we'd have no idea that the sun had gone. If there was no moon, then the water might spread across the planet equally and reduce the amount of friction. Earth / Uncommon Science / Universe. [8] If it takes two weeks before the particles fall, their radioactivity will go down 1,000-fold and we'll be able to make it through alive. Based on the day/night temperature differences, I would guess that we could loose about 5C or 10F a day (or more) for the first couple of weeks. We can assume that millions of years before this, Earth will have become uninhabitable. Photosynthesis would halt immediately, and most plants. This is due to their slower metabolisms and large sugar storage capacities. While some inventive humans might be able to survive on a Sun-less Earth for several days months or even years life without the Sun would eventually prove to be impossible to maintain on Earth. In theory we could. After about a billion years the sun will become hot enough to boil our oceans. Everything would simply freeze solid. Yo ho! A full moon is nearly two thousand times brighter than Venus is at its brightest. But it still wouldn't be enough to light up the sky. And without sunlight, the Earth would get very, very cold. And here is the answer I got from yahoo answers: As said above, at least 8 minutes and 19 seconds (it's a mean time for light to reach earth from the sun). A relatively simple calculation would show that the Earth's surface temperature would drop by a factor of two about every two months if the Sun were shut off. The sun is the anchor point of the solar system at 333,000 times the mass of Earth, it exerts a hefty pull that keeps the planets locked in their orbits. Without the Sun's rays all photosynthesis on Earth would stop. But we . During the Polar Night, which lasts from . Although some microorganisms living in the Earth's crust would survive, the majority of life would enjoy only a brief post-sun existence. The sun doesn't just go out in a bang, but rather the dying process takes millions of years. Jeremiah 8:2). The Earth's atmosphere has some capacity to hold in heat but not much of one. It is impossible for a human to have that. That's because these animals don't need the sun to live. "Humans don't have cholorphyll or chloroplasts. There's another side that does not face the sun that's really cold. This means the agricultural industry would crash and burn. No humans do. This means in two months the temperature would drop to 150K and 75K in four months.

Sadly, at the time God cast his people out of the land by means of the Babylonians, even in God 's own temple in Jerusalem the people were worshipping the sun (Ezekiel 8:16; cf. "This is huge, 99.9 percent of the natural productivity on Earth is done by photosynthesis, which requires the sun," Stevens says. There might be some heat accumulated in our atmosphere, as others have pointed out, that could be sufficient for a few seconds or minutes, but that would be insignificant in the absence of a Sun. We like to say that life on Earth could not survive without the sun, but that isn't actually true. For us on earth, it is a source of life. We need its light. Without the sun, our planet would get extremely cold, and all living things on it would die. In roughly 5 billion years, the sun will run out of energy and drastically alter the solar system. What would happen to life on Earth if the Sun were to burn out how long would we be able to survive? 2. Without sunlight plants would be unable to photosynthesise. Sun, the glowing planet in the sky. Skin cancer rates would soar, but we might not even live long enough to experience that cause of death [source: Carlowicz].

By contrast, darkness stimulates hormones, such as melatonin, that makes us tired and sleepy. This means that the earth would not slow, which then means that the hours of our days would change. Humanity has a 95% probability of being extinct in 7 800 000 years according to J. Richard Gott's formulation of the controversial Doomsday argument which argues that we have probably already lived through half the duration of human history. Very few things besides other suns could survive that kind of heat. And when that happens, the warm yellow orb at the center of our solar system will transform into a cooler . Most of us can survive the night without the sun. These thermophiles never see the Sun or encounter a breath of oxygen, but survive 2.4 kilometers (1.5 mi) below the sea surface. Even in Antarctica, the coldest place on our planet, temperatures seldom drop below minus 50C. A cup of hot coffee put in the refrigerator cools down instantly. Sir Roger has argued that when a person dies temporarily . This means that it is in the most stable part of its life . The top layers of the oceans would freeze over, but in an apocalyptic irony, that ice would insulate the deep water below and prevent the oceans from freezing solid for hundreds of thousands of years. Thanks to the wonderful oxygen in our atmosphere, food and water, and everything else that makes our home planet liveable, you can get in a good 80 years here. [+] 1.) So, if you straddle that zone it'd be like you rotated like in a rotisserie chicken and you would have cold and warm . Exact Answer: 7 days A plant in a dark room will die over time.

Humans would survive as long as our energy and food supplies would last. Most would die within a few weeks, while larger flora would continue to endure for several years, perhaps even decades. We need its energy. Without the Sun's rays all photosynthesis on Earth would stop. This will cause a massive increase in food prices, and it will also affect the health of the population. And without sunlight the Earth would get very very cold. It's not entirely clear how long it will take for the particles to fall. The evaporation of the Earth's oceans would be well underway by 1 billion years from now. Similarly, if the sun went out and its heat was suddenly "switched off", which in reality is physically impossible, the Earth, compared with the surrounding space, would remain hot for several million years . If humans survive a nuclear war, they would be able to adapt to their environment. Since the seasons take less than a few months to change the cooling would be rapid.

The sun would melt anything that got near it. After all, photosynthesis is how plants and some organisms use sunlight to make food from carbon dioxide and water. Our star is powered by nuclear fusion, and it turns hydrogen into helium in a process that converts mass into energy. A lack of sunlight will have wiped out all smaller plants by now, but the larger trees would still survive for a few decades without the need to photosynthesise. You may live even longer if you inhabit a "blue zone," one of the several places on Earth where people tend to live much longer than the general population. Entire planets will be consumed.
