We have yet to find any traces of extraterrestrial intelligence, a vexing problem known as the Fermi Paradox. The Universe as we observe it today is not as it was billions of years ago, nor does it appear as it will billions of years from now. New research accepted for publication in the Journal of the British Interplanetary Society suggests that conditions in our current Universe are far too warm for a digital, computer-based civilization, and that it makes sense for such beings to enter into a state of aestivation—hibernation, but in response to excess heat—until the cosmos is much colder in the far, far future.

Billions of years from now, the universe as we know it will cease to exist. The good news is, that…. But back up a sec: Indeed, an increasing number of futurists, astrobiologists, and SETI experts are starting to think that advanced intelligence eventually transitions into a digital mode of existence.

As computer scientists and information physicists know, the potential for information processing increases as temperature decreases energy is required to cool a blazingly fast computer, after all.

So rather than squander energy and resources in the current era, Sandberg and company believe it makes more sense for an advanced, computer-based civilization to aestivate and wait until the Universe is much colder than it is today.

The current background radiation of the Universe is publix supermarket stocks prices three degrees Kelvin above absolute zero. If they want to maximize processing they should not do it today but wait until the cold future when they will get tremendously more done.

They should hence aestivate. Specifically, he says we should be on really profitable binary options strategy named the sandwich lookout for process that prevent a variety of astrophysical phenomena: Another way to potentially detect these sleeping civilizations would be to mess with their stuff, but that could be very dangerous.

Which might make this a very risky way of testing the hypothesis. David Brin, an astrophysicist, SETI expert, and science fiction author, says the new paper is clever, but the concept has several flaws.

Anything else will get you less cake. He says an alien civilization can certainly strive to improve its computational efficiency in the current cosmological era, but while this might be what computation-maximizing civilizations do in the present, using up any resources now will mean far, far fewer resources in the distant future.

Brin thinks opportunistic, non-dataist aliens may find a way to breach the defenses really profitable binary options strategy named the sandwich the aestivators and wreak havoc. At the same time, the aestivation strategy is still something we may want to consider for ourselves in a few billion years, he added.
