For five years I had been researching a book on asteroid impacts, when I came across a mysterious event that happened in 1917 in Fatima, Portugal: "The Miracle of the Sun", where they talked about "the Sun changing colors", "dancing", "falling on the people", and a perplexing fact about the "drying of the garments" after a soaking rain. How could this be possible? I was so spellbound by the phenomenon and by the mystery it represented that I had to write another book, and after several years of work I solved the 104 years old puzzle. The Fatima event was real, not a hoax or mass hallucination. It was a small comet that entered our atmosphere and disintegrated completely. But a new mystery was exposed, and this one, I could not solve with our current knowledge. The event at Fatima was extraordinary. The probability of happening by chance was 1 in 61.428.000.000.000.000. Thus it has to be regarded as a miracle, in spite of the fact that it has a scientific explanation. Then, we are back into square one. How could this be possible?
