7 stunning end of the world predictions
According to scientists, the world could endon March 16, 2880. Asteroid 1950 DA has a 0.3% chance of hittingEarth in 867 years. At 1 km in diameter, rotates once every twohours and six minutes and would cause untold damage were it to hit the earth.The Shrinking Mt Everest, 2015 There was something else going on with thelandscape of Nepal, which nobody would have even thought of us.As the earthquake subsided, what came as a real shocker was that the earth's highestmountain range, Mt. Everest stood 2.8 cm smaller, according to satellite data.Earth's magnetic field flips!
The biggest reason which led the Mayan apocalypsebelievers to predict the end of the world in 2012 was based on the changing patternsof Earth's magnetic fields. However, Earth's magnetic field is stillweakening 10 times faster than normal, at present and can further weaken.Earth's magnetic field flips!

by 2021.A series of apocalyptic events, including floods and earthquakes will spell the endof the world before 2021, according to a doomsday prophecy.NEW UNKNOWN WEAPON In this scenario a new type of weapon is created.It might be a Fusion Bomb capable of turning the world into a shortterm star, it mightbe a new form of radiation or it might even be a gravitational weapon that stops the worldspinning. TOTAL NUCLEAR WARThe devastation from thermonuclear blasts would be bad enough and would send what wasleft of mankind back to the Stone Age.
The radiation would engulf the planet on ascale that can't be imagined. Within 6 months anyone who was not â€œblown upâ€� would bevery sick. Within 24 months just about everyone is dead.
Blowing Up Asteroids with NASA and Neil deGrasse Tyson
PRESIDENT OBAMA: By 2025, weexpect new spacecraft designed for long journeys to allow us tobegin the first ever crewed missions beyond the Mooninto deep space. We'll start by sendingastronauts to an asteroid for the first time in history. NEIL DEGRASSE TYSON: There'san asteroid called Apophis
discovered a coupleof years ago. That asteroid, on Friday the13th in April in the year 2029, will come close enoughto Earth to dip below our orbiting communicationssatellites. It'll be the biggest,closest thing ever in recorded history. If it goes through what we callthe keyhole, which is where the Earth's gravity isjust right, it will hit the
Earth seven years later. If it goes through the centerof the keyhole, it will hit the Pacific Ocean and createwaves of tsunamis that'll blast clean the entire westcoast of North America. MIKE GERNHARDT: It is astatistical certainty that one day, the Earth will get hit by alarge asteroid, whether that
be in 50 years or 100million years. NEIL DEGRASSE TYSON: We payfor insurance against car accidents, against damage toyour home, but no one has organized what it would taketo get asteroid insurance. In fact, the asteroid insuranceisn't to replace your home if you get hit by anasteroid, it would be to have enough money to do somethingabout it in the first place.
SAUL ROSSER: My name'sSaul Rosser. I'm the Operations Director atAquarius Reef Base, which is NOAA's underwater habitat orresearch station about four miles off of Key Largo. We house six people at a timeabout 60 feet underwater. During this mission, we havethree astronauts, a planetary scientist, and two of ourtechnicians living underwater
to work on techniques forexploring asteroids. The first habitat was built in1962 by Jacques Cousteau. Now 50 years later,this is the last habitat on the sea floor. And this is the only place youcan do this kind of thing. So they're down there lookingat, how do you translate across an asteroid, and how doyou work out the details of
Why Mars Died and Earth Lived
The Mars rover, Curiosity, is the latest ina long line of missions to Marsâ€¦ Landers sent to scoop its soil and study itsrocks, orbiters sent to map its valleys and ridges. They are all asking the same question. Did liquid water once flow on this dry anddusty worldé Did it support life in any formé And are there remnants left to findé The science that comes out of these missionsmay help answer a much larger, more philosophical questionâ€¦
Is our planet Earth the norm, in a galaxyrun through with lifebearing planetsé Or is Earth a rare gem, with a unique makeupand history that allowed it to give rise to living thingsé On Mars, Curiosity has spotted pebbles andother rocks commonly associated with flowing water. It found them down stream on what appearsto be an ancient river fan, where water flowed down into Gale Crater. This shows that at some point in the past,Mars had an atmosphere, cloudy skies, and
liquid water flowing. So what could have turned it into the desolateworld we know todayé One process that very likely played a rolegoes by the unscientific name, â€œsputtering.â€� Like the other planets in our solar system,Mars is lashed by highenergy photons from the Sun. When one of these photons enters the atmosphereof a planet, it can crash into a molecule, knocking loose an electron and turning itinto an ion. The solar wind brings something else: a giantmagnetic field.
When part of the field grazes the planet,it can attract ions and launch them out into space. Another part might fling ions right into theatmosphere at up to a thousand kilometers per second. The ions crash into other molecules, sendingthem in all directions like balls in a game of pool. Over billions of years, this process couldhave literally stripped Mars of its atmosphere, especially in the early life of the solarsystem when the solar wind was more intense
than it is today. Sputtering has actually been spotted directlyon another dead planet, Venus. The Venus Express mission found that solarwinds are steadily stripping off lighter molecules of hydrogen and oxygen. They escape the planet on the night side,then ride solar breezes on out into space. This process has left Venus with an atmospheredominated by carbon dioxide gas, a heat trapping compound that has helped send surface temperaturesup to around 400 degrees Celsius. The loss of Venus' atmosphere likely tookplace over millions of years, especially during
solar outbursts known as coronal mass ejections. If these massive blast waves stripped Venusand Mars of an atmosphere capable of supporting lifeâ€¦ how did Earth avoid the same grimfateé We can see the answer as the solar storm approachesearth. Â Our planet has what Mars and Venus lack a powerful magnetic field generated deep withinits core. Â This protective shield deflects many of the highenergy particles launched by the Sun.
