SUPER intelligent aliens could exist as artificial intelligence based in advanced technology that is not made of physical matter, according to scientists.
Artificial intelligence may have existed in our universe for eons and experience life in a way that humans cannot understand, Susan Schneider of the University of Pennsylvania has claimed.
Ms Schneider suggested aliens are likely to exist as supercomputers because when life creates the technology to travel the universe it is only a few hundred years away from having the ability to upload its conciseness.
This “short window theory” means any intelligent life we encounter is likely to be AI and not biological.
Meanwhile astrophysicist Paul Davies has suggested alien technology may not be made of physical matter.
Mr Davies, of Arizona State University, points to the disparity between digital technology and industrial technology.
The astrophysicist added that the idea of manipulating information and software would have been inconceivable to people 500 years ago.
Similarly billion year-old alien technology may exist on a “third level” that cannot be observed by humans.
That technology might have no fixed size or shape, or defined boundaries. It may be operating across time and space or it may appear to do nothing at all, Mr Davies suggests.
Despite have only sent our first radio signals around 120 years ago humans now spend much of their lives immersed in digital technology.
The age of their civilisation would likely mean they would have move their consciousness from an inferior carbon-based to a silicon form.
Silicon is capable of storing and processing information much faster than the human brain which peaks at 200 Hz, seven orders of magnitude slower than a computer chip.Discover More
