We’re on the cusp of discovering new applied sciences that “will take us even farther as we discover the planets and the celebs” — and lead us nearer to creating contact with alien life, writes Michio Kaku in “The Way forward for Humanity.”

We all know that one out of each 5 stars within the Milky Approach galaxy has an Earth-like planet orbiting it — which implies that there are greater than 20 billion Earth-like planets in our galaxy, in line with Kaku. Although there are different circumstances essential to creating life (there have to be a Jupiter-sized neighbor to maintain asteroids and particles out of the planet’s path and the Earth-like planet requires a moon to stabilize it), there appears to be loads of choices on the market for all times to exist.

The Seek for Extraterrestrial Intelligence (SETI) Institute, thanks partially to funding from Microsoft co-founder Paul Allen, devotes 42 high-powered telescopes to scanning one million stars to hear for alien communication.

Final 12 months astronomers despatched out a sign from the Norwegian metropolis of Tromsø, containing digital music and knowledge on geometry and binary numbers, hoping it can attain ET ears.

Dr. Seth Shostak of the SETI Institute instructed Kaku that he believes we’ll make contact earlier than 2025, although he upped that quantity by 10 years in a latest article for science journal The Nautilus.

“I’ve wager a cup of espresso to any and all that by 2035 we’ll have proof of ET,” Shostak wrote. “I’m optimistic by nature — as a scientist, it’s a must to be . . . I really feel that we’re on the cusp of studying one thing really revolutionary.”

However what would ETs appear to be as soon as we lastly meet them?

To search out out, Kaku interviewed consultants in exobiology, a subject that research what life may be like in distant worlds with totally different ecosystems. Based mostly on his analysis, Kaku determined that clever alien life would have three needed options:

  1. The aliens, like people, would have stereo imaginative and prescient, which permits eyes to check pictures and observe distance — a needed function in predators, who hunt and observe their prey. “In all probability, clever aliens in house could have descended from predators that hunted for his or her meals,” Kaku writes. “This doesn’t essentially imply that they are going to be aggressive, but it surely does imply that their ancestors way back might need been predators. We could also be properly served to be cautious.”
  2. The aliens would have some type of opposable thumbs or greedy appendages, needed for looking prey and creating instruments (which they must do to be refined sufficient to make contact).
  3. They might additionally have to have language. “To be able to hand down and accumulate important info from technology to technology, some type of language is essential,” Kaku writes.

As well as, Kaku theorizes that many alien civilizations will exist on ice-covered moons (like Jupiter’s moon Europa or Saturn’s moon Enceladus), the place life would exist fully underwater. So how would an aquatic species turn out to be really clever beings?

Kaku takes this thought experiment again to Earth. The one Earth-bound underwater animal that almost suits all of the above standards — stereo imaginative and prescient, graspable appendages — is the octopus, he writes. The cephalopod, which has survived on Earth for not less than 165 million years, solely lacks language.

On a special planet, nonetheless, cephalopods might simply develop language — in reality, if circumstances modified drastically on Earth, Kaku says it might even occur right here, too.

“On a distant planet below totally different circumstances, one can think about that an octopus-like creature might develop a language of chirps and whistles so it might hunt in packs,” Kaku writes. “One might even think about that sooner or later within the distant future, evolutionary pressures on Earth might power the octopus to develop intelligence. So an clever race of octopods is actually a chance.”

In order that’s what we will count on? An clever race of octopods, like within the film “Arrival”?

Shudder.

Michio Kaku additionally writes about mining asteroids for billions of dollars.
