How do astronomers predict planetary alignment?
Most use a computer program that can "fast forward" or "rewind" the night sky, since we know the laws governing movement.

About Planetary Alignment
Many have foretold a planetary alignment for the date 12/21/2012, which will signal the end of the world. But a true alignment of all the planets and moons means they would form a straight line leading directly to the sun, an event that scientists say would happen only happen once in 86,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years. The earth is only 4 billion years old now, so this wont happen any time soon.
