Susan Schneider of the University of Connectict and the Institute for Advanced Studies at Princeton says that the first aliens we may encounter will be machines and could be billions of years old.
Schneider said in a Daily Galaxy report, ‘all lines of evidence converge on the conclusion that the maximum age of extraterrestrial intelligence would be billions of years, specifically ranges from 1.7 billion to 8 billion years.’
The reason? It’s all about probability – and how long it takes alien civilizations to evolve from developing radio communications to becoming immortal cyborgs. Many scientists believe that the period from the discovery of radio waves, to organisms turning themselves into immortal robots will be relatively brief.
Schneider says, “I do not believe that most advanced alien civilizations will be biological. The most sophisticated civilizations will be post-biological, forms of artificial intelligence or alien super-intelligence.“
Although this theory is been dismissed by Ancient Astronauts proponers, many scientis as Seth Shostak of the Search for Extraterrestrial Intelligence believe that it is not only possible, but probable. He said:
“Consider the fact that any signal we pick up has to come from a civilisation at least as advanced as we are.
“Now, let’s say, conservatively, the average civilisation will use radio for 10,000 years. From a purely probabilistic point of view, the chance of encountering a society far older than ourselves is quite high.”
