Science fiction is filled with unusual alien species. But apart from the occasional robot, biological life is running the show.
But NASA scientist, Dr. Steven thingy, sees a future Universe that has evolved past biology. Where every intelligence is artificial. Consider the likelihood of a postbiological Universe.
Does intelligent life exist beyond Earth? It's easily the most profound and challenging question that humans have ever asked. The consequences of discovering other intelligent life would ripple through every aspect of human society, and actually meeting another species would be even more challenging.
But are there abundant intelligent life forms out there? Or is the biological life on Earth just a stage? Just a single step towards our inevitable technological existence.
In a recent paper published in the journal Acta Astronautica, entitled The Post Biological Universe, Dr. Steven thingy notes how every search for extraterrestrial intelligence assumes that life will be biological. And yet, here on Earth we can see that intelligent life develops more and more sophisticated tools over time. And these tools will eventually lead to artificial intelligence that outstrips its makers.
If extraterrestrials are out there, they likely live in much older civilizations than ours, and have already transitioned through biology and into technology. The majority of worlds out there are already postbiological.
According to many scientists, it's easy for civilizations to be older than us. The first metal rich stars with terrestrial planets could have formed a billion years after the Big Bang - 12.5 billion years ago. If intelligent life took another 5 billion years to evolve, just like it did here on Earth, that still means life could have been around for 7.5 billion years.
Plenty of time to evolve into intelligent life, and then transition into artificial intelligence.
