The Fermi Paradox

Astronomers at the University of Auckland claim that there are approximately 100 billion planets in the Milky way that mirror the conditions of Earth, making them habitable and giving them the ability to support life. For a planet to be considered habitable, it must be a comfortable distance away from a star, it must rotate on its axis and revolve, and it must have the ability to sustain an atmosphere. With 100 billion planets in our galaxy sharing these strict characteristics, it is unreasonable to assume that Earth is the only planet that holds

Even though the three big reasons why aliens do not exist has been explained for this argument, there are still smaller reasons that add to the fact that there are no other existing alien civilizations other than ours here on Earth. One of those reasons is that governments do not give very much evidence supporting the existence of alien civilization. In fact, European governments have completely disclosed everything they know about UFO’s. The only evidence most governments give out to the public is testimonial evidence. There has never been any real hard physical evidence. Another reason is that scientists, in a sense, know that aliens can not exist, but they use the ridicule excuse as a cover up to explain why they do not admit UFO’s are real. Scientists are supposedly afraid of the ridicule they would receive if they would happen to admit aliens do exist. On the other hand, scientists lie and cheat to gain fame and fortune for all kinds of research and investigations. The discovery of UFO’s would make them big and famous, but yet all

We live in a universe that is about 46 billion light years old. In a world, as massive as ours there must be some form of extraterrestrial life out in the galaxy. For thousands of years ancient peoples, such as the Greeks, have wondered the same question. Are we alone? As our technology advances, things such as videos and photographs are surfacing of people claiming to see such alien life. Whether it is an unidentified flying object, or if it’s from someone claiming to see an actual alien, there are thousands of people that believe they have seen proof. Some also claim that the government is hiding things behind our backs, like the Roswell UFO incident for example. Though many people refuse to believe in the existence of alien life forms until they see evidence, the fact that multitudes of people have eye-witness accounts, the improbability that we are alone, and the idea that we have thought of aliens so long, bring forth the evidence that proves something is out there.

However, due to the technological evolution and the industrial and mechanical revolution, sky was not an unsurpassable limit anymore, but what lied beyond that sure was. By the time the first telescope was made, space’s conquest has been a goal that first world’s nations have been trying to fulfill. Simultaneously though to that goal’s fulfillment, a question popped up that created numerous new theories and propagandas. Are we alone in this vast universe? And if we are not, how does it look or behave those who coexist with us?

Exobiology is the science that is concerned with the search for life in outer space; it may be called as astrobiology as well. The search for life in outer space has consumed the imagination of the humankind for long time ago. Nowadays, humankind has made a progress and found major discoveries in the quest for life existence in the universe and outer space because of the advancement of the technology. However, in the past, exobiology was considered as a science without a subject, where the people and other scientists laughed at and ridiculed the famous scientist and biologist Joshua Lederberg when he originated the term exobiology. Some people argue that life exists elsewhere in the universe, however, others believe that life only exist on Earth. A new study reveals that our galaxy, the Milky Way, has 100 billion or so stars, where 17 billion of them are Earth-size alien planets, and probably many more. The huge size of the galaxy increases the probability of life existence in the outer space. Are we alone in the universe? This question has captured the imaginations of scientist, theologians, and astrobiologists. However, they don’t know the answer yet. Understanding the complete definition of life and how life originated, and determining the techniques used for searching for life existence in outer space and evidences found can help to answer the question of “Are we alone in the universe?”

The Milky Way in which we live in is expanding 3.25 million light years per second (Moskowitz). By the time you finish reading this paper, the Milky Way will have expanded by 1.9 million light years. This might be a lot but the closest galaxy to the Milky Way is 13.2 billion light years away. This means there is a chance extra-terrestrial life might exist by the time you finish reading this paper. While saying this, the galaxy is made up of two hundred billion stars in which NASA has discovered. Each of these stars has at least one planet orbiting it. By saying this if the Sun has one habitable planet orbiting it, what is the chance of another star having a habitable planet circling it? Peter Behroozi, a Hubble fellow at the University of California Berkley talks about this issue, “For every grain of sand there is, there are ten other planets out there like Earth” (Cofield). Astronomers have only seen our galaxy, and there are galaxies larger than the Milky Way and more

Among the billions of stars in each galaxy, many have planets that revolve around them. At least a few are bound to be of the right size and have the correct spatial orientation with respect to their star to allow life to grow. We believe this because life exists on the Earth. Astronomers have concluded that there must be hundreds of billions of other stars with conditions approximating those of the sun. Therefore there could be a million earth like planets with advanced civilizations in the Milky Way galaxy alone (Stilley). It is very probable that there is intelligent life elsewhere in the universe.

Thinking about the Universe as a consciousness computer and how the right atoms bump into the right other atoms, we conclude that we are the product of energy, movement, and matter touching matter, says Gregg Braden. He also declares that, as in a computer program, nature uses a few simple, self-similar, and repeating patterns – fractals – to build atoms into the familiar patterns of everything, from elements and molecules to rocks, trees, and us.

Is there life in the vast universe? Can they communicate with us? These questions have been around for decades. But, lately numerous articles have been appeared in the media at an explosive rate. As it can be expected, not all the articles are credible, moreover a portion of them uses fallacies to attract the reader’s attention and to create inadequate controversy. As an example, Joel Achenbach in his article of February, 28, 2015, published on the Washington Post with the title of “Do we really want to know if we’re not alone in the universe?” exposed logic fallacies as his writing denotes that aliens are aware of us because of the radio transmission that the humanity have been broadcasting since TV and radio existed (Par. 6), interstellar

The Search for Extra-Terrestrial Intelligence(SETI) has been searching for life for more than fifty years and have yet to find anything (Waldrop 442). SETI has ran on $2.5 million annual costs from powerful telescopes to hundreds of dishes worldwide and have managed to find no signs of other life forms (Waldrop 444). The search of life outside of Earth remains to be unanswered and now many ask, where are they? Through SETI’s large budget and expensive equipment the possibility of life on other planets becomes very slim. However, the lack of evidence for any possible forms of life does not justify the possibility of life forming in other unobservable places. The possibilities of life formation in other solar systems can be countless. In “Where Are They?,” Nick Bostrom states that there are over 100 billion galaxies in what we can observe of the universe and our galaxy alone has 100 billion stars (Bostrom 2). This alone provides the reason to believe that somewhere in our observable universe there are many planets with similar conditions and probability of life forming. It took Earth approximately 3.5 billion years to allow life to form that started with single celled prokaryotes to humans (Bostrom 3). The prokaryotes only formed after earth provided an ideal state in which life could be formed. It is also known that many of the galaxies contain stars and planets much older than ours (Bostrom 2). This gives endless amounts of time frames in which life of began in galaxies far way or nearby. The points of evolution become countless within each galaxy, yet the visibility of technological life civilizations like ours is nowhere to be seen. This means there is something preventing these civilizations from passing our current level of civilization. This known as the Great Filter, a theory, in which specific steps are prevented in the timeline of the evolution of

In the depths of space you can find my group of scientists, soldiers and me, General Spear commander of the QWERTY spaceship. We work under the POIU corporation to discover the ends of space and if there is more life forms in the universe. We know that the universe is expanding at an exponential rate and we wonder if it has gifted us any more life forms or discoveries.

To begin with, there is more than one sun out there in space, and a sun can contain about one million planets in space. Scientists have discovered about one thousand planets orbiting distant stars. They have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets.

After the Big Bang for another galaxy it will take 30 million years for any human-like creatures to form. So, unless they formed before us or when we were forming to become what we are now, they probably are not any aliens in the universe. We also have no scientific discoveries, just reported sightings. There’s a good chance that there will be aliens in the future than right now.

Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started.

To be the only intelligent life on a planet in our galaxy would be a miracle. Shostak bets that we will pick up a signal from ET intelligence in the next twenty-four years considering the advancement in technology and the amount of potential planets. If we were to hear from ET life, they would be a society way more advanced compared to ours by thousands or millions of years and the amount we could learn from them would be a huge jump on our own advancement and evolvement. That being said, finding life on other planets would make us feel less special and like less of a miracle. “It is, philosophically, a very profound thing to learn.”-Seth Shostak. On a more positive note, seeing a society advanced years ahead of us would let us know we are not doomed for self-destruction by being overrun by our own
