1. A billow of abrogating activity engulfs the solar system. Wow! A aphotic billow with a bad attitude! This complete cautiously like a Brilliant Trek episode. Aphotic activity is all about us already, but it is not packaged into clouds. The aforementioned goes for aphotic matter.
2. Supernovae or hypernovae will brighten Earth.
There are no stars that are so abutting to Earth that radiation from their supernova annihilation would actively affect us. The abutting candidate, the red behemothic Betelgeuse, is predicted to backfire in the abutting 1,000 years. The monster brilliant Eta Carinae is additionally on a abbreviate fuse. Neither bedevilled brilliant has a circuit arbor absolutely aimed at Earth, so we don't accept to anguish about actuality absurd by a attenuated axle of gamma application ejected from the core's implosion. In actuality the kinds of stars that shoot out these Death Brilliant beams are aberrant in the Milky Way. Earth has a one percent adventitious of accepting zapped over 10 billion years. Scratch gamma ray bursts off of your homeowner's allowance policy.
3. The rogue planet Nibiru will beat by Earth.
There isn't such a planet any added than the planet Naboo from the Brilliant Wars leash is real. Purported Internet pictures of the alien are accurate lens flares or hoaxes. Don't accept every dot you see photographed in the sky.
4. An asteroid will accident into Earth.
A aggressive near-Earth asteroid that's gotten the best columnist is the 900-foot advanced Apophis. But its affairs of blow accept been downgraded to 1 in 250,000 at its abutting abutting access in 2029. In theory, an alien asteroid or comet could appear out of the dejected tomorrow. But if we don't apperceive about it today, the Mayans absolutely didn't apperceive about it 1,200 years ago. Earth-killer impacts are tens of millions of years apart. So there's no acumen to be a doomsday clock-watcher.
5. The atramentous aperture in the galactic centermost will affect us.
The Milky Way's atramentous aperture has no access on the galactic disk. The atramentous aperture is three actor solar masses. The Milky Way is several abundance solar masses back we add the tug of aphotic matter. Any gravitational access of the atramentous aperture over the galaxy would be like the appendage wagging the dog. The Milky Way's blow with the Andromeda galaxy will dump gas into the atramentous aperture and it will bonfire as a quasar. But that's several billion years away.
6. The Sun will adjust with the galactic equator on the winter solstice.
So what? These are artlessly coordinates in the sky. It has no concrete absoluteness any added than the circle of Broadway and 7th Avenue at Times Square influences the cartography of Manhattan Island. This is abundantly abashed with the actuality that the sun's position absolutely oscillates up and bottomward as it orbits the galaxy, like a horse on a carousel.
We canyon through the galactic even every 35 to 40 actor years. It's accessible that an added cardinal of comets ability be hurled appear the Earth because of gravitational alternation with the densest genitalia of our galaxy during this passage. But we are talking about the after-effects spanning abounding bags of years, not abolition bottomward on our active in any one specific year.
7. A admirable alignment of Jupiter and Saturn will gravitationally adjy Earth.
For the accomplished several decades there accept been doomsday claims that the accumulated force from admirable all-embracing alignments will account geologic and meteorological upheavals on Earth.
None are appointed for 2012.
In 1962 an acutely attenuate admirable affiliation of the classical naked-eye planets collection astrologers crazy. The affiliation happened on Feb. 4-5 and was accompanied by a solar eclipse! The best abominable admirable affiliation was in 1982 and affected in a book alleged "The Jupiter Effect," which predicted earthquakes and massive tides. Life went on as accepted both years. The moon has a awfully greater gravitational access on Earth than Jupiter. It's alleged location, location, location! At a whopping ambit of 400 actor afar from Earth, Jupiter's tug is appealing wimpy.
8. The Earth's circling arbor will tip.
This isn't about as accessible as angled cows. Unlike Mars, which does go admitting advanced excursions in it axial tilt, Earth's angle is kept abiding by the gravitational access of the moon. An article the admeasurement of Mars would accept to hit Earth to alteration abundant drive to beating us out of kilter. But Mars-sized protoplanets were kicked into interstellar amplitude over 4 billion years ago. The solar arrangement doesn't accomplish "planets-gone-wild" anymore.
9. The Earth's alluring acreage will reverse.
Don't authority you breath. The aftermost acreage changeabout happened about 800,000 years ago. Fred Flintstone and our added antecedent cavemen survived. Geological affirmation shows that the acreage has antipodal its acclimatization tens of bags of times over Earth history. Yet there is no absolute affirmation that a alluring acreage changeabout has anytime acquired any accumulation afterlife due to added catholic ray influx.
10. Changes in the Sun's alluring acreage will advance to able flares.
So what abroad is fresh beneath the sun? The sun goes admitting a well-documented 11-year sunspot aeon that is apprenticed by its alluring acreage entangling, reforming and flipping polarity. Yes, the aiguille of the abutting aeon is in 2012 (or 2013), and some predictions advance it ability be 30 to 50 percent stronger than the aftermost peak.
But experts say it will absolutely not be the better aiguille anytime recorded.
The basal band is that no dragon's animation of blaze will amplitude beyond 100 actor afar of amplitude and blowtorch Earth. The better solar blaze recorded to date, on Nov. 4, 2003, spewed several billions of bags of claret in Earth's direction. The flare's X-ray radiation that impacted our careful atmosphere had the agnate radiation of 5,000 suns.
