Scientists have proposed a rather interesting reason for the reason why we have not yet found strangers, a problem known as the Fermi paradox (if life is so abundant, where is everyone?). They propose that intelligent extraterrestrials may be in a state of hibernation, waiting for the universe to become colder so they can be more productive.
This idea was proposed in the Journal of the British Interplanetary Society, with a preprint available on arXiv. The paper was written by Anders Sandberg, Stuart Armstrong and Milan Cirkovic of the Institute of the Future of Humanity at Oxford University, and was recently resumed by Gizmodo.
Some people think that a much more advanced civilization than ours could become a digital race. That is, they will live in artificial intelligence inside computers, suppressing more limited charnable bodies. Experts, including Elon Musk, have suggested that this is a logical progression in the future.
If we are not alone in the universe (which we do not yet have any proof of), we could therefore propose more that an advanced foreign race could have descended in this direction. But to get the most out of their new digital bodies, they might not like the universe right now.
The temperature of the universe at this time is 3 degrees Kelvin above absolute zero. It is quite cold, but this temperature will continue to fall as the universe develops. Sandberg and colleagues claim that the temperature in the future could allow 1030 other computer processes than is currently possible.
"We therefore suggest a" topical hypothesis "," the researchers write in their journal, adding that "the reason why we do not observe the manifestations of extraterrestrial civilizations is that they are currently (most of the Time) inactive, patiently await the future cosmic epochs ". Is basically hibernation to avoid warmer temperatures, and not the cooler ones.
