Last year too NASA had debunked the conspiracy theory of a giant supernova engulfing Earth by saying: "Given the incredible amounts of energy in a supernova explosion - as much as the sun creates during its entire lifetime - another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth. However, given the vastness of space and the long times between supernovae, astronomers can say with certainty that there is no threatening star close enough to hurt Earth.
Astronomers estimate that on average about one or two supernovae explode each century in our galaxy. But for Earth's ozone layer to experience damage from a supernova, the blast must occur less than 50 light-years away. All of the nearby stars capable of going supernova are much farther than this."
The scientists all over the world are asking the public not to believe in gibberish websites spreading rumours about doomsday. All this kind of stuff is a hoax. As we know that the Internet is a great tool to access information in a jiffy. But, the Internet can become dreadful also because every person, good and evil, can add information to it to exercise his or her freedom of speech. But on the other hand, it's a free-for-all bazaar of the bizarre and truth, accuracy and reliability can take a nosedive when they get in the way of a good story, warns a website debunking doomsday hoax.
