2012 Doomsday Hoax

Sudahkah Anda menonton film 2012? Film ini mengisahkan tentang bencana besar yang diperkirakan akan terjadi pada tahun tersebut. Namun, tahukah Anda banyak fake science yang dimasukkan dalam film tersebut? Jadi, Anda tidak perlu khawatir dunia akan segera kiamat karena tidak ada alasan dan bukti kuat tentang ramalan semacam itu. Berikut ini akan ditampilkan sebuah artikel dari universe today, yang menuliskan pendapat NASA tentang isu-isu yang tidak benar yang diperkirakan orang (bahkan dengan bodohnya dipercaya orang) akan terjadi di tahun 2012 (khususnya di tanggal 21 Desember 2012).


NASA is now joining in to combat the 2012 nonsense. Don Yeomans, manager of NASA's Near Earth Object office has produced a video and written an article, providing the scientific realities surrounding the celestial happenings of 2012. Yeomans has done a wonderful job explaining everything that is and isn't going to happen in 2012, and we're happy to add his work to our collection of 2012 debunking articles.

The Galileo spacecraft's view of the Moon and Earth On December 16, 1992, 8 days after its encounter with Earth, the Galileo spacecraft looked back from a distance of about 6.2 million kilometers (3.9 million miles) to capture this remarkable view of the Moon in orbit about Earth. Image credit: NASA/JPL There apparently is a great deal of interest in celestial bodies, and their locations and trajectories at the end of the calendar year 2012. Now, I for one love a good book or movie as much as the next guy. But the stuff flying around through cyberspace, TV and the movies is not based on science. There is even a fake NASA news release out there… So here is the scientific reality on the celestial happenings in the year 2012.

Nibiru, a purported large object headed toward Earth, simply put – does not exist. There is no credible evidence – telescopic or otherwise – for this object's existence. There is also no evidence of any kind for its gravitational affects upon bodies in our solar system.

The Mayan calendar does not end in December 2012. Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period, but then – just as your calendar begins again on January 1 – another long-count period begins for the Mayan calendar.

There are no credible predictions for worrisome astronomical events in 2012. The activity of the sun is cyclical with a period of roughly 11 years and the time of the next solar maximumis predicted to occur in the period 2010 – 2012. However, the Earth routinely experiences these periods of increased solar activity – for eons (very long period of time -red) – without worrisome effects. The Earth’s magnetic field, which deflects charged particles from the sun, does reverse polarity on time scales of about 400,000 years but there is no evidence that a reversal, which takes thousands of years to occur, will begin in 2012. Even if this several thousand year-long magnetic field reversal were to begin, that would not affect the Earth’s rotation nor would it affect the direction of the Earth’s rotation axis… only Superman can do that.

The only important gravitational tugs experienced by the Earth are due to the moon and sun. There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible. Each December the Earth and Sun align with the approximate center of the Milky Way Galaxy but that is an annual event of no consequence.

The predictions of doomsday or dramatic changes on December 21, 2012 are all false. Incorrect doomsday predictions have taken place several times in each of the past several centuries. Readers should bear in mind what Carl Sagan noted several years ago; "extraordinary claims require extraordinary evidence."

For any claims of disaster or dramatic changes in 2012, the burden of proof is on the people making these claims. Where is the science? Where is the evidence? There is none, and all the passionate, persistent and profitable assertions, whether they are made in books, movies, documentaries or over the Internet, cannot change that simple fact. There is no credible evidence for any of the assertions made in support of unusual events taking place in December 2012.

Duh, nih orang gak ada kerjaan amat bahas 2012. Udah jelas cuma film dan kiamat gak ada yang tau, malah dibahas pula. Cape deh

@anonymous: tapi banyak orang yang percaya. oleh sebab itu, harus di-clear kan. bagus artikelnya...
