Our 4.5 billion-year old Solar System exits in a universe that is estimated to be between 13.5 and 14 billion years old. Experts believe that there could be advanced civilizations out there that have existed for 1.8 billion years.
Lord Martin Rees, a leading cosmologist and astrophysicist who is the president of Britain’s Royal Society and astronomer to the Queen of England. Has said that he believes the existence of extra terrestrial life may be beyond human understanding.
“They could be staring us in the face and we just don’t recognize them. The problem is that we’re looking for something very much like us, assuming that they at least have something like the same mathematics and technology.”
“I suspect there could be life and intelligence out there in forms we can’t conceive. Just as a chimpanzee can’t understand quantum theory, it could be there as aspects of reality that are beyond the capacity of our brains.”
