Prologue
The Geeks, the frail heart humans and the atheists.
The Sun
About 1.2 billion years from now, the sun will begin to change. As the hydrogen fuel in its core is used up, the burning will spread outward toward the surface. This will make the sun grow brighter. This increased radiation will have a devastating effect on our planet.The mean surface temperature of the earth will rise from about 68°F to 167°F. The earth’s oceans will evaporate. The planet will become a stark, lifeless desert.
Finally, as it approaches the age of 5-8 billion years, the sun will run out of hydrogen almost entirely. When the sun uses hydrogen to create energy, it changes it to helium. After all these years, the core of the sun will be filled with left-over helium. This helium will become unstable as it begins to collapse under its own weight. The core of the sun will become even denser and hotter. As this happens, the sun will swell one-and-a-half times its normal size and grow more than twice as bright as it is now.
Over the next 700 million years, it won’t grow any brighter . But it will continue to grow larger. It will swell to more than twice its present size.. It will become 166 times larger than the sun we knew. As it does so, it will cool down a little. From the parched surface of the earth, the sun will look like an enormous orange ball hanging in the misty sky.
It is necessary and also not necessary that is what theory and hypothesis is about,the core of science is a dispute and a struggle to the answers.
Geo Magnetic reversal and Islam
One of the portents of the Judgment Day revealed in the hadiths of our Prophet (pbuh) is “The Rising of the Sun in the West”: Our beloved Prophet Mohamed (Peace Be Upon Him) said: “One of the signs of the (Last) hour..the sun will rise from the west, where no longer tauba (forgiveness) will be granted”
Earth's Magnetic Field Flip Could Happen Sooner Than Expected
Changes measured by the Swarm satellite show that our magnetic field is weakening 10 times faster than originally predicted, especially over the Western Hemisphere
Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm.
The biggest weak spots in the magnetic field — which extends 370,000 miles (600,000 kilometers) above the planet's surface — have sprung up over the Western Hemisphere, while the field has strengthened over areas like the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites — three separate satellites floating in tandem.
"Such a flip is not instantaneous, but would take many hundred if not a few thousand years," Floberghagen told Live Science. "They have happened many times in the past.
Scientists already know that magnetic north shifts. Once every few hundred thousand years the magnetic poles flip so that a compass would point south instead of north. While changes in magnetic field strength are part of this normal flipping cycle, data from Swarm have shown the field is starting to weaken faster than in the past. Previously, researchers estimated the field was weakening about 5 percent per century, but the new data revealed the field is actually weakening at 5 percent per decade, or 10 times faster than thought. As such, rather than the full flip occurring in about 2,000 years, as was predicted, the new data suggest it could happen sooner.
Floberghagen hopes that more data from Swarm will shed light on why the field is weakening faster now.
Researchers think power grids and communication systems would be most at risk.
Earth's magnetic field acts like a giant invisible bubble that shields the planet from the dangerous cosmic radiation spewing from the sun in the form of solar winds. The field exists because Earth has a giant ball of iron at its core surrounded by an outer layer of molten metal. Changes in the core's temperature and Earth's rotation boil and swirl the liquid metal around in the outer core, creating magnetic field lines.
The movement of the molten metal is why some areas of the magnetic field strengthen while others weaken, Florberghagen said. When the boiling in one area of the outer core slows down, fewer currents of charged particles are released, and the magnetic field over the surface weakens.
"The flow of the liquid outer core almost pulls the magnetic field around with it," Floberghagen said. "So, a field weakening over the American continent would mean that the flow in the outer core below America is slowing down."
The Swarm satellites not only pick up signals coming from the Earth's magnetic field, but also from its core, mantle, crust and oceans. Scientists at the ESA hope to use the data to make navigation systems that rely on the magnetic field, such as aircraft instruments, more accurate, improve earthquake predictions and pinpoint areas below the planet's surface that are rich in natural resources. Scientists think fluctuations in the magnetic field could help identify where continental plates are shifting and help predict earthquakes.

2012: Magnetic Pole Reversal Happens All The (Geologic) Time
Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to 'south.' This is because a magnetic compass is calibrated based on Earth's poles. The N-S markings of a compass would be 180 degrees wrong if the polarity of today's magnetic field were reversed. Many doomsday theorists have tried to take this natural geological occurrence and suggest it could lead to Earth's destruction. But would there be any dramatic effects? The answer, from the geologic and fossil records we have from hundreds of past magnetic polarity reversals, seems to be 'no.'
Wow Nasa is on a whole new level of stupidity,fossil records showed that ancient creatures like the dinosaurs had cancer and brain tumor,however what instigated dinosaur cancer because of solar radiation possibly or cell trans-mutated cancer is unknown.
Reversals are the rule, not the exception. Earth has settled in the last 20 million years into a pattern of a pole reversal about every 200,000 to 300,000 years, although it has been more than twice that long since the last reversal. A reversal happens over hundreds or thousands of years, and it is not exactly a clean back flip. Magnetic fields morph and push and pull at one another, with multiple poles emerging at odd latitudes throughout the process. Scientists estimate reversals have happened at least hundreds of times over the past three billion years. And while reversals have happened more frequently in "recent" years, when dinosaurs walked Earth a reversal was more likely to happen only about every one million years.
