The Fermi Paradox

Leave a comment

Are We Alone In The Universe?

So far, we have no evidence to the contrary, and yet the odds that not one single other planet has evolved intelligent life would appear, from a statistical standpoint, to be quite small. There are an estimated 250 billion (2.5 x 10?? ) stars in the Milky Way alone, and over 70 sextillion (7 x 10?? ) in the visible universe, and many of them are surrounded by multiple planets. The shear size of the known universe is staggeringly and inconceivably vast. The odds of there being only one single planet that evolved life among all that unfathomable vastness seems so incredible, that it is all but completely irrational to believe. But then “where are they?” asked physicist Enrico Fermi while having lunch with his colleagues in 1950.
Fermi questioned, if there are other advanced extraterrestrial civilizations, then why is there no evidence of such, like spacecraft or probes floating around the Milky Way. His question became famously known as the Fermi Paradox. The paradox is the contradiction between the high estimates of the probability of the existence of extraterrestrial civilizations and yet the lack of evidence for, or contact with, any such civilizations. Given the extreme age of the universe, and its vast number of stars, if planets like Earth are at all typical, then there should be many advanced extraterrestrial civilizations out there, and at least a few in our own Milky Way. Another closely related question is the Great Silence, which poses the question: Even if space travel is too difficult, if life is out there, why don’t we at least detect some sign of civilization like radio transmissions?
Milan Cirkovic of the Astronomical Observatory in Belgrade, points out that the median age of terrestrial planets in the Milky Way is about 1.8 gigayears (one billion years) greater than the age of the Earth and the Solar System, which means that the median age of technological civilizations should be greater than the age of human civilization by the same amount. The vastness of this interval indicates that one or more processes must suppress observability of extraterrestrial communities.
Since at this point, there is no direct and/or widely apparent evidence that extraterrestrial life exists, it likely means one of the following:
We are (A) the first intelligent beings ever to become capable of making our presence known, and leaving our planet. At this point, there are no other life forms out there as advanced as us. Or perhaps extraterrestrial life does exists, but for some reason extraterrestrial life is so very rare and so very far away we’ll never make contact anyway—making extraterrestrial life nonexistent in a practical sense at least.
Or is it (B) that many advanced civilizations have existed before us, but without exception, they have for some unknown reason, existed and/or expanded in such a way that they are completely undetectable by our instruments.
Or is it (C) There have been others, but they have all run into some sort of “cosmic roadblock” that eventually destroys them, or at least prevents their expansion beyond a small area.
The ancients once believed that Earth was the center of the universe. We now know that Earth isn’t even at the center of the Solar System. The Solar System is not at the center of our galaxy, and our galaxy is not in any special position in contrast to the rest of the known universe. From a scientific viewpoint, there is no apparent reason to believe that Earth enjoys some privileged status. Since Earth’s placement in space and time appears to be unremarkably random, proposition “A” seems fairly unlikely. Assuming humans evolved like other forms of life into our present state due to natural selection, then there’s really nothing all that mystical, special or remarkable about our development as a species either. Due to the shear numbers, there are almost certainly other planets capable of supporting at least some form of life. If that is so, then for Earthlings to be the very first species ever to make a noticeable mark on the universe, from a statistical perspective, is incredibly unlikely.
For proposition “B” to be correct would defy all logic. If potentially thousands, or even millions of advanced extraterrestrial civilizations exist in the known universe, then why would all of them, without exception, choose to expand or exist in such a way that they are completely undetectable? It’s conceivable that some might, or perhaps even the majority, but for all of them to be completely undetectable civilizations does not seem likely either.
Proposition C in some ways, appears to be more likely than A or B. If “survival of the fittest” follows similar pathways on other worlds, then our own “civilized” nature could be somewhat typical of extraterrestrial civilizations that have, or do, exist. Somehow, we all get to the point where we end up killing ourselves in a natural course of technological development and thereby self-inflict our own “cosmic roadblock”. “Perhaps the most disturbing aspect of the Fermi Paradox is what it suggests for the future of our human civilization. Namely, that we have no future beyond earthly confinement and, quite possibly, extinction. Could advanced nanotechnology play a role in preventing that extinction? Or, more darkly, is it destined to be instrumental in carrying out humanity’s unavoidable death sentence?” wonders Mike Treder, executive director of the Center for Responsible Nanotechnology (CRN).
Treder believes that some of the little understood new technologies now being developed such as nanotech, and others, could well be either our salvation or just as likely end up causing our ultimate destruction. “Whatever civilizations have come before us have been unable to surpass the cosmic roadblock. They are either destroyed or limited in such a way that absolutely precludes their expansion into the visible universe. If that is indeed the case—and it would seem to be the most logical explanation for Fermi’s Paradox—then there is some immutable law that we too must expect to encounter at some point. We are, effectively, sentenced to death or, at best, life in the prison of a near-space bubble,” suggests Treder. “Atomically-precise exponential manufacturing could enable such concentrations of unprecedented power as to result in either terminal warfare or permanent enslavement of the human race. Of course, that sounds terribly apocalyptic, but it is worth considering that the warnings we heard at the start of the nuclear arms race, and the very real risks we faced in the height of the Cold War, were but precursors to a much greater threat posed by an arms race involving nano-built weaponry and its accompanying tools of surveillance and control.”
When we consider the chronological history of life on Earth, humans have only existed for a small fragment of time and our existence has always been precarious. The entire time we’ve existed, we been banding into various groups and attempting to kill each other—or at least are constantly in the process of developing more effective ways of killing each other—just in case. The US government, for example, spends on “Defense” (including “preemptive” warfare) and Homeland Security, 8 times what it spends on educating the next generation. There is enough nuclear weaponry in storage around the world to kill every living creature on the planet several times over. Clearly, we’re a species with poor odds of surviving indefinitely.
Our self-destructive natures aside, curiosity may end up killing more than the cats. The faster technology is advancing, the more our “leap now, look later” nature appears to grow as well. If evolution on Earth serves as a somewhat typical template for evolution of other life forms, then becoming a truly advanced civilization must be a very daunting task indeed and a very rare, if not impossible, achievement. In fact, Sir Martin Rees, Great Britain’s Astronomer Royal and respected professor of astrophysics at Cambridge University has estimated that humans have only a 50-50 shot of making it through the 21st century. If Rees is right, and our standing on the planet is as precarious as he and others believe it is, then we may be alone due to a built-in evolutionary self-destruct button. Others have come before and others will exist after, but the cosmic roadblock may be an innate, finite nature, which only allows sentient life forms to exist for a very small window of time—windows of life which may be too small for our civilization to match up with the small windows of other civilizations that have been before or will come after.
In a contrary point of view, Milan Cirkovic believes that highly efficient city-state type of advanced technological civilizations could easily pass unnoticed even by much more advanced SETI equipment, especially if located near the Milky Way rim or other remote locations.”

Stephen Hawking warns over making contact with aliens

Mr Hawking says it is ‘perfectly rational’ to believe in aliens

Aliens almost certainly exist but humans should avoid making contact, Professor Stephen Hawking has warned.

In a series for the Discovery Channel the renowned astrophysicist said it was “perfectly rational” to assume intelligent life exists elsewhere.

But he warned that aliens might simply raid Earth for resources, then move on.

“If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans,” he said.

Prof Hawking thinks that, rather than actively trying to communicate with extra-terrestrials, humans should do everything possible to avoid contact.

He explained: “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.”

In the past, probes have been sent into space with engravings of human beings on board and diagrams showing the location of our planet.

Radio beams have been fired into space in the hope of reaching alien civilisations.

Prof Hawking said: “To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.

“The real challenge is to work out what aliens might actually be like.”

The programme envisages numerous alien species including two-legged herbivores and yellow, lizard-like predators.

But Prof Hawking conceded most life elsewhere in the universe is likely to consist of simple microbes.

Well, called.

If the aliens that come here are as much megalomaniacs as we are, but with technology that we don’t have (obvious, because they got here, we didn’t get there) we are not in deep space, we are in deep shit.

His analogy with Europeans arriving in America is very apt.

What was Flying over Santiago, Chile 4 Days Ago?

4 Comments

On the 17th & 18th of December this year several glowing orbs, which looked like an alien fleet was observed over Santiago, Chile.

Usually these things are pronounced a hoax, but these seem to be filmed  from three different sources.

The wonderful thing about the mainstream media, not a word has been printed in five days…

UFOs, are they real?

I note that no air or military authority has commented either, maybe this one is too hard to explain.

Ural Relief Map

 


In terms of mysteries, few come along as incredible and irrefutable as The Ural Relief Map. In 1995, Aleksandr Chuvyrov, Professor of Mathematical and Physical Science at Bashkir State University in Russia, was investigating hypotheses of the immigration of Chinese Migrants to Siberia and the Urals. During his research he heard an account from the 18th century telling of a series of strange white slabs scrawled with some unknown language. As they were supposedly situated in an area central to his study, a remote village named Chandar the southern Urals, he thought the stones could be of Chinese Origin. and organized a team and helicopter to try and locate them. After several searches and village hopping in his helicopter he could find no trace of the elusive stones. It was then that a village elder approached him and asked him to take a look at a strange slab he found in his back yard. The slab he was taken to was the Ural Relief Map, also dubbed ‘The Map of the Creator’

Showing a relief scale of the entire southern Urals, the slab accurately shows its three main rivers, the Belya, Ufimka and Sutolka, as well as the Ufa canyon. After the map was studied further it was understood to show a giant irrigation system, consisting of two 500 meter wide channel systems, 12 dams, each 400 meters wide, 10km long and 3km deep. It is calculated that 1 quadrillion cubic meters* of earth were shifted to allow for the dams to be built. After initial tests failed to provide an age for the stone, a breakthrough was made when 2 types of prehistoric shell were found embedded in its surface, Navicopsina munitus and Ecculiomphalus Princeps. The former existed 500 million years ago, while the latter existed 120 million years ago. Scientists place its actual age at 120 million years. A geological test of the slab concluded that it consisted of 3 layers, the base being 14cm thick dolomite, the second being a diopside glass unknown to science, while the third is a protective layer of calcium porcelain. Chuvyrov said ‘It should be noted, that the relief has not been manually made by an ancient stonecutter. It is simply impossible. It is obvious that the stone was machined.’ X rays confirmed it was made by precision tools. Interestingly scientists believe that the map is actually part of a relief map of the entire world, due to the crudeness of the areas around the maps’ perimeter. Soil tests of 400 types of soil in the area, in comparison to the ones found embedded on the stone, have allowed scientists to narrow down the possible location of other pieces to 4 specific areas around the village of Chandar. So what is the Ural Relief Map? God’s discarded blueprint? Ancient Extra Terrestrial resource chart? It remains a Mystery.

Discovered so many years ago, been in the news ten years ago, but since then… NOTHING!

This is another example of somebody doesn’t want everybody to know something. Keep the people stupid.

Are Humans the Result of Alien Colonization?

Colonization

Source: wikicommons

Dr. Charles Lineweaver an astronomer, who studied planetary formation, concluded that any other life form in the Universe would probably have had 2 billion years longer to evolve than us, making us the “new kids on the block”.

Some experts have said that using nuclear power, a speed of 1/10th the speed of light could be attained. They say that assuming an intelligent life form, only used this source of power; they could colonize the whole galaxy in a period of 1 – 10 million years.

These facts led to some scientists saying: if aliens existed, we would have seen them by now, we haven’t and so they cannot exist.

Earth

Other scientists though, say these facts could support the ancient alien theorists.

Some of these have said that perhaps aliens colonized the Earth and when the inhabitants of Earth started to show signs of intelligence, they moved on. This could account for the reason why we have not seen aliens in recent history but our ancient ancestors did.

Others have theorized that Earth was the subject of alien colonization but over time, as earths inhabitants grew in intelligence the colonizers bred with them. Humans are the result of this mix of DNA, a kind of Creole between Aliens and Earthlings.

Once again, this theory could support the fact that only our ancient ancestors seem to have seen aliens. We only see ourselves and do not see ourselves as aliens.

 

  • Have We Been Visited by Aliens.
    There are many stories of aliens visiting our ancient ancestors. This highlights a couple of them that although they are so well known, are perhaps a little more believable.
Ancient Monuments

Ancient Ancestors

We may never know the answer to the question of whether we had been colonized in our ancient history.

One thing though is certain. The existence of ancient monoliths, temples, pyramids and cities, shows that our ancient ancestors seem to have had advanced technologies or advanced machinery.

The colonization theory could explain this. Also why, the technology does not still exist today.

Our astronauts today know how to fly their spacecraft and also know how to use the machines they take with them. They may even know how to fix some of these. However, I am sure they do not know how to build them, assuming that on whichever planet they landed they had the raw materials to do so.

It is therefore logical to assume that any alien colonizers would only have a certain amount of hardware. Yes, they may have received resupply but as their colonization continued to spread throughout space, these probably became fewer and fewer, eventually coming to an end.

True, we have not yet found any such technology buried among the ruins but then again, depots may not have been marked by pyramids. Besides, for all we know the alien technological machines may have been made of materials that are bio-degradable on Earth.

Whether you believe in ancient aliens or not, you must find it a mystery as to what technology the ancients possessed to be able to build such monuments. You must also wonder as to what happened to that technology.

  • United Nations Appoints Ambassador for Aliens.
    Now that the UN has appointed an Ambassador for Aliens we must ask why? What is it they know that we don’t? What does it mean to our future?
  • Proof of Alien Existence by 2026
    The senior scientist at SETI makes a wager that proof of aliens existence will happen by 2026. How can he be so confident?
  • Aliens Grave Found in Africa
    An alien graveyard has been found in Africa. Once again, as in other similar cases, after one immediate report, secrecy seems to take over. What is it that the authorities do not want us to know and why?
  • Religion and Aliens
    There are many stories of our ancestors being visited by aliens. Is it just a co-incidence that our concepts of religion began during this same period?
  • Will We Be Re-Visited By Aliens.
    Many people are now convinced that we have been visited by aliens at some time in our past. What we should now be asking is: will they return?

ET Phone home!

A question that I have often considered is, “Why are we so fascinated by the stars, what impels us to leave Earth, spending so much money that could be well used here?

My answer is that we are trying to go home.

Maybe ET wasn’t so far wrong; we are trying to phone home.
