  1. Kaitlyn Bless, Tevin Strange, David Ching, Gilbert Gomez PP.3.2 What would happen if the Sun burned out?

  2. Base Knowledge of the Sun • It’s over 800,000 miles across. • You could line up more than 100 Earths, each touching the next, and still not span the diameter of the sun. • The sun can make 333,000 Earth-size planets out of it. • The sun’s surface temperature is about 5500 degrees Celsius.

  3. While the density of the sun’s core is greater than that of any materials here on Earth, the sun’s overall density is not even 50 percent higher than that of water. • Each second, about 700 million tons of hydrogen is converted into helium by the sun. • Source: Other Worlds by James Trefil

  4. Earth-Sun Relationship • The Earth-Sun relationship has molded the Earth into what we know it to be, in the current day. • By affecting the climate, landscape, and even the atmosphere. • These affected traits have three primary influences.

  5. The Three Influences 1. The nearness of the sun. 2. The composition of the gasses that make up our atmosphere. Which has come to about 80% Nitrogen and 20% Oxygen. 3. Also the simple mass of the Earth, and the heat that radiates from the core.

  6. Why We Believe the Sun Will Die • Scientists, examined the simple chemical reaction that the sun, used to produce so much energy. They could not determine, with drawing similarities to terrestrial energy sources, what could produce so much energy over a long span of time.

  7. Understanding the Sun Burning Out • If you put a steamy cup of coffee in the refrigerator , it wouldn't immediately turn cold. Likewise, if the sun simply "turned off" (which is actually physically impossible), the Earth would stay warm—at least compared with the space surrounding it—for a few million years. But we surface dwellers would feel the chill much sooner than that.

  8. Effects to the Temperature • Within a week, the average global surface temperature would drop below 0°F. In a year, it would dip to –100°. 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.

  9. Millions of years after that, our planet would reach a stable –400°, the temperature at which the heat radiating from the planet's core would equal the heat that the Earth radiates into space, explains David Stevenson, a professor of planetary science at the California Institute of Technology.

  10. Life on Earth • Although some microorganisms living in the Earth's crust would survive, the majority of life would enjoy only a brief post-sun existence. Photosynthesis would halt immediately, and most plants would die in a few weeks.

  11. Large trees, however, could survive for several decades, thanks to slow metabolism and substantial sugar stores. • With the food chain's bottom tier knocked out, most animals would die off quickly, but scavengers picking over the dead remains could last until the cold killed them.

  12. Human Survival • Humans could live in submarines in the deepest and warmest parts of the ocean, but a more attractive option might be nuclear- or geothermal-powered habitats.

  13. Iceland • One good place to camp out: Iceland. The island nation already heats 87 percent of its homes using geothermal energy, and, says astronomy professor Eric Blackman of the University of Rochester, people could continue harnessing volcanic heat for hundreds of years

  14. Orbital Pull Of course, the sun doesn't merely heat the Earth; it also keeps the planet in orbit. If its mass suddenly disappeared (this is equally impossible, by the way), the planet would fly off, like a ball swung on a string and suddenly let go. source: http://www.popsci.com/node/24698
