Armageddon
Mount Armageddon (Ancient Greek: Ἁρμαγεδών Hebrew: הַר מְגִדּוֹ, Har Megiddo, Arabic هرمجدون, Late Latin: Armagedōn) is the site of a battle during the end times according to some sects within the Abrahamic religions. It is a term in common usage to describe the end of times and Judgment Day.
There is no such concept in Buddhism.
The Buddha described a 10,000 world systems, which was to say that there are literally an innumerable amount of solar systems. A world system was the description for a sun or star with several planets revolving around it. We now know that there are several solar systems through direct evidence with high powered space telescopes. Nearly one hundred planets have been identified in the known universe up to this point. The Buddha stated that "the infinite world spheres are incalculable" (KN, Buddhavamsa 1.64).
Through the use of these high powered telescopes, located in orbit, scientists have been able to come up with some ideas on the formation of our own solar system. Scientists have observed the formation of other solar systems with the telescopes. It appears that new planets form around a new star from debris in the universe. A current theory is that the origin of this debris is from the destruction of a previous solar system.
This would seem to suggest that solar systems are formed, go through their normal life course of about 10 to 50 billion years and then perish. The debris leftover eventually reconstitutes itself in a transformation and becomes a new solar system. This is one hundred percent compatible with the Buddha’s teachings on no first beginning and the cycles of existence. The Buddha said that even world systems get destroyed, but that there is no end. There is no beginning and there is no end. Everything is just transformed in continuation with no death:
"He recalls to mind his various temporary states in days gone by; one birth, or two or three or four or five births, 10 or 20, 30 or 50, a 100 or a 1,000 or a 100,000 births, through many cycles of cosmic contraction and cosmic expansion . . . Now there comes a time, when sooner or later, after the lapse of a long, long period of contraction, this world-system passes away. And when this happens beings have mostly been re-born in the World of Radiance, and there they dwell made of mind, feeding on joy, radiating light from themselves, traversing the air, dwelling in glory; and thus they remain for a long, long period of time. Now there comes also a time, friends, when sooner or later, this universe begins to re-evolve by expansion." (The Buddha, Brahmajala Sutta, Digha Nikaya, Sutta Pitaka)
This quote from the Buddha is virtually exactly how modern scientists are describing the evolution and re-evolution of the universe.
Natural disasters and Armageddon
Frequently when natural disasters occur, there will be one or more famous clergy members from various religions (except Buddhism) stating that the occurrence of many natural disasters is proof that the end of times is near and that this will be the latter days when Judgment Day is imminent. This has occurred with several natural disasters over at least the last 1,000 years. They state that the increase in natural disasters, in particular, is proof that the end of times are near. Yet the end does not come and life goes on. But this does not stop further speculation by various ministers when a major natural disaster occurs.
Today's famines and armed conflicts are fewer and relatively smaller than those in the 20th century, and the frequency of major earthquakes has remained about the same. Natural disasters occur in every century and even the major ones with tens of thousands of deaths or more occur in every century, in every generation and are nothing new nor are they occurring any more frequently.
