WILL THE WORLD END?
Come the 21st of December, the earth will end- according to the doomsday prophets, that is. Their dire predictions are based on the calender used by the ancient Maya, which reaches the end of the long term cycle on the fateful day, but scientists know that these prophecies are widely inaccurate. If your looking for the Apocalypse, forget calenders- its meteor strikes, super volcanoes, hyper novas and pandemics that you should be worried about. First, lets look at the prediction of the ancient Maya.
A celebration for the Maya
the latest prediction for the end of the world-Dec.21,2012-stems from the ancient Maya Calender. Fantasists believe that the ancient Maya were predicting our demise on this date, but scientists maintain that the Maya would have viewed it as we do New Years Eve.the Maya have a complex numerical system to be i track of dates, which they made an important calender. The calender began with the mythical creation of Aug. 11,3114 BC, and its longest cycle, the B'ak'tun, lasted for 144,000 days (just over 394 years). When our calender reaches Dec.12,13 of these long periods-some 5,125 years- would have passed.

THE ATOM
Continued...
... so, in logic that means that each atom has its own mass. So this is the very basics of an atom and the things inside the atom are called sub-atomic particles. So the nucleus is made out of protons and neutrons, that is why these are called nucleons(because they are in the nucleus). If you add the number of neutrons and protons in an atom, you get the total mass of the atom. What about the electrons? Well, before i explain that i have to explain about this.
Well, some people might think that the electron orbits around the nucleus just like the earth orbits the sun. This is a very old idea that the electrons orbit the nucleus but this idea is completely wrong. No one has ever proven whether they do orbit or stay rigid but for now, think that they are just teleporting and moving at the speed of light.
That is why electrons have no mass, because the move at the speed of light .
This is the the basics of an atom. But there is more to it. Read my other articles to find out
