In August 1977 an Ohio State University radio telescope detected an unusual pulse of radiation from somewhere near the constellation Sagittarius. The 37-second-long signal was so startling that an astronomer monitoring the data scrawled “Wow!” on the telescope’s printout. The signal was within the band of radio frequencies where transmissions are internationally banned on Earth. Furthermore, natural sources of radiation from space usually cover a wider range of frequencies. As the nearest star in that direction is 220 million light years away, either a massive astronomical event – or intelligent aliens with a very powerful transmitter would have had to have created it. The signal remains unexplained.
Explaination ; Time and Space is interwarped with black holes that makes time travel possible in the future, civilisations from the past and future are looking for alien life forms, but they will be disappointed, the only evidence will point to the existence of different time zones in space.
God is a mysterious being, He left plenty of evidence everywhere throughout time for those who truly seek Him, and unravell all His mysteries, even the bible is a prophesy of past, present and future, where there is a possibility to change the future if you believe, nothing is constant, which testify to the greatness of God. That is the reason why I do not believe in any doomsday prophesy, God will not destroy His own creation again. – Contributed by Oogle.
