Question by yousif: why are the solar eclipses happening in shorter periods of time?
in the past it didn't happen in short periods but now it happens always
in 2011 another solar eclipse will happen and is it truly a sign of world's end?
Best answer:
Answer by suittiNot all solar eclipses are the same length. But their duration can be predicted - it's hairy math, but computers can cope.
In the mean time, the Moon really is moving away from the Earth. And in a short period of time, it might only be 50,000 years, the Moon will be too far away to cast shadows. No more eclipses. It appears to be a cosmic accident that the apparent size of the Moon and the Sun are so close to being the same at this point in history.
But 50,000 years puts the end of the world well past 2012, right? And that's what this question is about.
