pelo menos segundo artigo do discovery channel.
eles bem começam atacando as explosões solares, que são justamente meu maior receio. vamos dar uma olhada resumida na lista de mitos (nem sabiam que eram tantos!)? segura minha mãozeenha e vem comigo!
10. changes in the sun's magnetic field will lead to powerful flaresexperts say it will certainly not be the biggest peak ever recorded.
9. the earth's magnetic field will reverse.
the last field reversal happened nearly 800,000 years ago. fred flintstone and our other ancestor cavemen survived.8. the earth's rotation axis will tip.
an object the size of mars would have to hit earth to transfer enough momentum to knock us out of kilter.7. a grand alignment of jupiter and saturn will gravitationally perturb earth.
the moon has a vastly greater gravitational influence on earth than jupiter. it's called location, location, location! at a whopping distance of 400 million miles from earth, jupiter's tug is pretty wimpy.6. the sun will align with the galactic equator on the winter solstice.
so what? these are simply coordinates in the sky. it has no physical reality any more than the intersection of broadway and 7th avenue at times square influences the geology of manhattan island.5. the black hole in the galactic center will affect us.
the milky way's black hole has no influence on the galactic disk.4. an asteroid will smash into earth.
a threatening near-earth asteroid that's gotten the most press is the 900-foot wide apophis. but its chances of collision have been downgraded to 1 in 250,000 at its next close approach in 2029.3. the rogue planet nibiru will swing by earth.
there isn't such a planet any more than the planet naboo from the star wars trilogy is real.2. supernovae or hypernovae will irradiate earth.
there are no stars that are so close to earth that radiation from their supernova demise would seriously affect us.1. a cloud of negative energy engulfs the solar system.
wow! a dark cloud with a bad attitude! this sound suspiciously like a star trek episode. dark energy is all around us already, but it is not packaged into clouds. the same goes for dark matter.
