Alien Civilizations May Number In The Trillions, New Study Says

Alien Civilizations May Number In The Trillions, New Study Says

The possibility that we earthlings are not truly alone in the universe has gained some added credibility, thanks to a new study that coincides with NASA’s recent planetary discoveries. The research, published in the journal Astrobiology last week, suggests that more planets in the Milky Way galaxy may harbor advanced civilizations than we previously imagined.

Study co-authors Adam Frank and Woodruff Sullivan looked at recent discoveries of potentially habitable exoplanets and considered the odds of whether sophisticated civilizations existed on them in the past or present.

“What we showed was the ‘floor’ on the probability for a civilization to form on any randomly chosen planet,” Frank, a University of Rochester physics and astronomy professor, told The Huffington Post in an email. “If we are the only civilization in cosmic history, then that what we calculated is the actual probability nature has set. But if the actual probability is higher than that floor, then civilizations have happened before.” 

Frank says the potential number of planets orbiting their parent stars within a habitable distance is staggering.

“Even if you are pretty pessimistic and think that you’d have to search through 100 billion (habitable zone) planets before you found one where a civilization developed, then there have still been a trillion civilizations over cosmic history!” Frank wrote. “When I think about that, my mind reels — even if there is just a one in a 100 billion chance of evolution creating exo-civilizations, the universe still has made so many of them that we are swamped by histories other than our own.”

In 1961, astronomer Frank Drake — founder of the SETI Institute (SETI stands for “Search for Extraterrestrial Intelligence”) — devised what is now known as the “Drake equation” to estimate the number of planets that may be home to civilizations with the ability to communicate beyond their world.

Frank and Sullivan created a new equation, which appears at the bottom of the illustration below. While the Drake equation calculates the number of advanced alien civilizations that could exist in the Milky Way galaxy, Frank and Sullivan’s equation expands the question to calculate the number of advanced civilizations that have existed in our galaxy throughout the whole history of the universe.

Two equations consider the possibilities of technological alien civilizations in the Milky Way galaxy: At top, the 1961 Drake equation and, at bottom, a more recent equation by Adam Frank and Woodruff Sullivan.

The variable factors that Drake and others consider when attempting to come up with figures about ET-inhabited worlds include:

  • The rate of formation of stars with planets suitable for intelligent life.
  • The number of those stars that have planetary systems.
  • The number of those planets which may have life-sustaining environments.
  • The number of those planets where life develops.
  • How many of those planets produce intelligent life.
  • How many of those intelligent life forms could produce technology, such as radio signals. 

In their Astrobiology paper, Frank and Sullivan write:

“Recent advances in exoplanet studies provide strong constraints on all astrophysical terms in the Drake equation. We set a firm lower bound on the probability that one or more technological species have evolved anywhere and at any time in the history of the observable universe.”

The two scientists address what they refer to as “the cosmic frequency of technological species.”

“The universe is more than 13 billion years old,” Sullivan, of the astronomy department and astrobiology program at the University of Washington, said in a statement. “That means that even if there have been 1,000 civilizations in our own galaxy, if they live only as long as we have been around — roughly 10,000 years — then all of them are likely already extinct. And others won’t evolve until we are long gone.

“For us to have much chance in finding another ‘contemporary’ active technological civilization, on average they must last much longer than our present lifetime,” Sullivan said.

The search for extraterrestrial signals has been ongoing for decades.

“With so many stars and planets filling the cosmos, it boggles the mind to think that we’re the only clever life to have made an appearance,” SETI Institute senior astronomer Seth Shostak told HuffPost in an email. “Frank and Sullivan use new research indicating that roughly one in five stars is orbited by a planet that could nurture biology. After that, it’s just a matter of counting up the tally of stars in the visible universe, and saying that — with all the suitable real estate that’s out there, if we’re the only place with intelligent life, then we’ve really won the mother of all lotteries.”

Shostak cautions against being overly optimistic or pessimistic about the SETI Institute’s searches for intelligent signals from possible outer space neighbors.

“The odds that no one is out there are very, very small. It’s a bit like an ant coming out of its hive, seeing the enormous amount of real estate stretching in all directions and deciding that, if its home is the only ant hill, then its existence is a near-miracle. Or, put another way, the calculation by Frank and Sullivan quantifies Jodie Foster’s statement in [the movie] ‘Contact’ that, if there’s nobody out there, it would be a ‘waste of space,’” said Shostak.

Scientists searching for extraterrestrial beings — and, yes, to those beings, we would be aliens — are like archaeologists combing a vast space for treasures and information to learn more about the history of our species.

NASA / REUTERS This colorful deep space image captured by the Hubble Space Telescope was released by NASA in 2014. What’s astonishing about the image is that it depicts a very small portion of the sky but shows approximately 10,000 galaxies, each made up of billions of stars.

“I love the notion of a cosmic archaeological question. I think this puts an important new spin on the question about the rise of technological communicating intelligence,” Penelope J. Boston, incoming director of NASA’s Astrobiology Institute at Ames Research Center, told HuffPost.

“We have only been looking for other intelligences for a few decades in a galaxy of unfathomable proportions,” Boston said. “Of course we haven’t found anybody yet. I think it is childish to imagine that we should somehow have started looking, and bingo, there they are! I have trouble finding my dropped contact lens in the grass. Should I then disbelieve in the reality of my contact lens?”

While scientists had long wondered if there were other planets orbiting stars in the Milky Way galaxy and elsewhere, it wasn’t until the early 1990s that the first extrasolar world was confirmed.

“The existence of planets orbiting stars other than the sun is a 2,500-year-old question that has been entirely answered over the last 20 years,” said Frank. “We now know that every star in the night sky has at least one planet orbiting it, and many of those are in the right place for life to form.

“Ten thousand years from now, no one will remember anything about our era except it was when we discovered this single profound fact: We live in a cosmos of planets.”

  1. Don’t believe in negative aliens and if they did exist they would surely be isolated or fought eliminated. Yes there are demons devils and what have you its what is referred to as the dark forces, bases of the universe is positive and negative which produces magnetism which is the hub of order, so to speak there couldn’t be a god without its relation to an anti god the dark forces, if god is omnipresent so must be temptation except heaven, don’t like the idea of treading on blasphemy

  2. Every time they speak of Aliens, they mean beings that do not look like us. In the message of Christ, ”
    INTRODUCTION TO ASCENSION by Sananda/Jesus, He said, ” Majority of human creation in the Universe look like us. Most of the negative ET do not look like us.”

  3. It boggles my mind when peoples say aliens are demons , so basically they are saying in this vast universe we are the only civilized and good people and the rest are just demons . If you are capable of any rational thinking you would immediately believe it is an absurd idea . They are millions of years ahead of us probably and they are the demons ??? Hahahahaha

  4. I believe in the big bang theory but also someone/something started it there cant just be one god who created him what came first chicken or the egg we’ll probably never know but there is something changing in our universe that’s for sure

  5. “heaven” could be just an excotic planet somewhere in the universe for all we know, the recycled effect. You don’t ascend unless you’ve learned your lesson. And who said we had to die first to do it ether? The Tibetans Book of the living and dead has an interesting angle also.

    • At this present time in my life, I see Heaven as the highest dimention. We get there with the waking of our supressed consciousness, Soul. Step at a time. I continue to remain open for further treading. <3

    • Tibetans? Now these people have do have a knowledge out of this world they were in direct contact with aliens most peaceful that went into great depth and found about the human body and its capability in relation to the cosmos

    • Things that are obscure in the Biblical presentations are clearly explained by Christ in His New Scriptures sent into the world in this 21st century. Many does not believe it exist, but this is the best time for Christ to expose the distortions made to the Bible we are using now which were compiled during the time of Emperor Constantine. And He did it in His New Scriptures and your beliefs will be positioned in their proper perspective.

  6. Christ said in His New Scriptures. ( not the Bible), “The Cosmos is vastly inhabited….” Throughout the Universe, life thrives…
    ( AUTHOBIOGRAPHY: Paragraph 24.)

  7. Why go to the extreme let them admit to one first then can we suggest the number of planets are inhabited or good to be inhabited by aliens. On my side I have long made my research and got my personal conclusion that aliens come in different kind and forms starting from man going off to beyond humans imagination highly intelligent telepathic come under one banner for peace only wars is against diseases and illiteracy some planets have more then one sun in time we will be part of the overall confederation as is the main idea for new settlement on new planets then shall begin the golden age and saucers will be a common sight equality advantage for all in harmony, thing is are we ready for the big change

    • Great story Ghassan Kalmoni. It sounds like science fiction, but hopefully we of our generation can experience it, before we head to another dimension! Better sooner, than later. Howver, not everybody will be able to handle it. Takes more time.

    • It’s nothing more then science fiction but sense it appeals to you never the less , we all have a way to create a scenario to fit our world this is my thoughts running wild be it real or fancy or is it just a hope no matter how much we delve into the fictitious realm especially the elusive topic of aliens its rather difficult to say when reality becomes unreal because we know nothing of it to start off with I find deep ideas more interesting then shallow ones I am not a scientist but a simple cook my information is based on my personal imagination

  8. I have often said that only that only an idiot could conceive that God would create that huge universe little ole insignificant us. If so, we are repaying Him horribly disrespectful for his efforts. What did make us significant is the fact that we are the only bi-lateral created beings in the universe, and with the capability to procreate with Alien Beings, AKA the Anunnaki. This is why Enoch was the only man taken up to the heavens, because Anu, the King of Nibiru wanted to see for himself that he was real and discovered that he was begotten by his son EA/ENKI. The first human/Alien conception.

  9. Demons, yeah cos we’re the only ones, right! If space is infinite, there must be an infinite number of suns so all those solar systems must be full of demons! Get real, unless you really believe the earth was made in 6 days, hahahahahahahahahahahahahahahahahahahaha

  10. There are an infinite number of other universes,galaxies,solar systems,planets…what ever elements/forces have made life here on Earth can quite easily have done so in an infinite number of other places as well. It is very arrogant of humans to assume our planet is the only 1 throughout the whole of space with life on it.

  11. Therr may not be any alian civilisations as there is the possibility that we are a premature planet we could be the only civilisation. …..just saying …….its a thought
