"Speak My Will, Make Yourself a Prophet!"
© ChandraCassiopeia A, a supernova remnant, is approximately 300 years 'old' and has the distinction of being the strongest radio source that is observable outside our solar system.
At any given point in time there seems to be at least one charlatan running around predicting the imminent end of the world. In 2011, radio evangelist Harold Camping predicted the world's faithful would be 'Raptured' on 21 May 2011. Of course, the date turned out to be a total dud, prompting Camping to 'revise' his prediction to October 21. Needless to say, at the time of writing we weren't holding our breath, and with good reason. We might have passed out and missed another apocalyptic non-event!
But is there such a thing as valid prophecy or prediction of future events? The results of
the Cassiopaean Experiment suggest that there is indeed such a thing, and more (e.g., remote access to unconventional knowledge, whether obscure or just previously unheard of). But the Cs have presented a very unique take on the subject of prediction. It is intimately tied with their cosmology and their view on 'time'. According to the Cs, our universe is a 'free will' universe and time is not a strictly linear 'one-off' phenomenon. That means the future is open. More on that below.
Most predictions are based on a pretty simplistic, and probably completely false, view of reality. According to this mechanistic idea, the universe was originally set in motion at some imaginary 'beginning' point in time by some equally imaginary 'first cause'. Religions have called this first cause 'God' while scientists have deemed it the 'Big Bang'. Once the machine has been set in motion, it obeys physical laws and plays itself out like clockwork. Theoretically, with enough data, every event in this mechanistic chain of cause and effect can be predicted. So when some prophet gives a prediction of a future event, he or she is basically operating on the assumption that because 'God' or some other divine being is omniscient and can see how everything will play itself out (and assuming this being actually exists, and that it is not simply pulling a cosmic practical joke on its subject), it's gotta be right. But things aren't that simple.
