There are many prophecies dependent on which on 21st December 2012 the world will end. This date is meant to mark the end of a cycle of the Mesoamerican long count calendar which is said to be about a 5125 year old cycle. Some individuals interpret the importance of this date differently and say this date will mark the beginning of some changes and transformations. They think that Earth and its inhabitants will undergo positive spiritual and physical evolution. This date is pretty much open to different interpretations, some say it will mark the end of the Earth others say it will mark a new start.

There are several ideas about how the end of the planet will occur. Some advocate the idea that a plant called 'Planet X' or Niburu will collide with the Earth and will destroy the Earth and therefore cause the end of the planet. Originally this event was forecast to occur in the year 2003 but was then ignored because it did not occur in 2003. By the year 2012 the activity of sun is also anticipated to extend. The sunspots might increase which may cause a harsh rise in the temperature of the Earth's surface. Nostradamus, who was a very famous clairvoyant, also foretold that the end of the Earth will occur in December 2012. Many of Nostradamus's prophecies have been proven right till now and many still haven't occurred.

An Indian Guru, Guru Kaliki Bhagavan has promoted throughout the country that 2012 will be the end of the Kal Yug. Kal is AKA the degenerate age. Millions of people accept that Guru Kalki Bhagavan is an incarnation of Lord Vishnu. He has also declared that in 2012 the human race will be enlightened spiritually.

The magnetic poles of Earth are shifting continuously. It's been recorded that the North Pole is shifting toward Siberia. Due to this shifting of the magnetic poles serious changes in climate are occurring. The shifting of the magnetic poles is causing in the magnetic flux which in turn is also causing the softening of ice caps. The liquefying of ice caps is often accredited to only global temperature increases but the change in magnetic flux is one more reason which is causing the ice to melt. The changing magnetic flux is also causing lots of magma activity. This magma activity is causing the motion of tectonic plates which is steadily increasing the frequency of tremors. The Bible scriptures say that a war will occur in the middle east and something will occur which should melt the flesh. This can be translated to be a holocaust thanks to a nuclear bomb. Also in the Book of Revelation it is written that mountains will become valleys and valleys will become mountains. Conditions of serious cold will triumph and there'll be starvation.

These days there are several disasters all around the globe. There are famines and droughts all over. These events can be seen as a sign of the end of the Earth which is coming.

In the study of astronomy axial tilt is sometimes called obliquity. The axial tilt is defined as the angle between the revolving axis and the line perpendicular to the orbital plane of an object. Currently Earth's axial tilt is 23.4. The orbital plane of Earth is sometimes known as ecliptic plane and thus the there is another name for Earth's axial tilt 'obliquity of the ecliptic'. This axis remains tilted in the same direction throughout the year.

This indicates that when one hemisphere is pointing at the sun during 1/2 of the year then in the other 1/2 of the other hemisphere will point towards the sun. This is the phenomenon behind the change of season. Whichever hemisphere is tilted towards the sun receives more quantity of daylight each day.

Also at midday the sunlight strikes at an angle which is closer to vertical, this results in more energy being received per unit area.

In Polar Regions the obliquity is very low this causes the Polar Regions to receive lesser solar energy and the conditions become agreeable for the formation of glaciers. While at the regions near the equator the axial tilt of the earth is greater and thus the daylight received is more in these regions. The Earth's axial tilt isn't a fixed quantity. It keeps changing and the cycle has a period of time of approximately 41,000 years. The understanding of Earth's axial tilt is terribly essential for making astronomical calculations and making observations from the outer surface of the Earth. In the 10th century, Abu Mahmud Khojandi measured the Earth's axial tilt. He made the measurements using the principle with a giant sextant. He revealed that the value of the tilt was lower than those measured by earlier astronomers , he so concluded that the Earth's axial tilt is not a continued quantity.

The earth's axial tilt varies between 22.1 and 24.5. At present the tilt is decreasing. As well as this steady drop off in the value of the tilt there are one or two smaller short term divergences. These are referred to as nutations and are generally due to the changes in the airplane of the orbit of the moon. This phenomenon can change Earth's axial tilt by about 0.005 degrees in and or minus.

The four seasons that we experience are a result of the Earth's axial tilt. Together with the earth's revolution round the sun the seasons are also caused by the axial tilt of the earth.

At the end of the nineteenth century Simon Newcomb worked out the Earth's axial tilt and discovered that the value is twenty-three 27' 8.26". This worth was accepted till improved telescopes were developed. These telescopes authorized more accurate findings to be made. The electronic computers authorized more elaborate models to be made which could enable better and more precise calculations. In the year 1976 Lieske developed an updated model which had an axial tilt equal to 23 26' 21.448". This model has become a part of the approximation formula that has been advised by the Global Astronomic Union in the year 2000.
