Essay about Possibility of Life on Other Planets

Darwin’s theory of evolution was a ground-breaking discovery for the study of life. Although Darwin gets most of the credit for the discovery his influences Charles Lyell, the father of geology and Erasmus Darwin, a pre-Darwinian evolutionist, made great contributions to the theory. The majority of the scientific community was quite receptive to Darwin’s evolution by natural selection theory because it provided an explanation for many things that the current origin of life theory, special creation, did not. The scientific community did have some trouble accepting his work because it did not describe how the evolving genes were transferred from generation to generation which was a very important piece of information that would solidify his for

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

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.

Darwin began to form his ideas when he served as official naturalist on a world voyage on HMS Beagle from 1831 to 1836 and spent the rest of his life back in England developing them (Singh 2). When his famous book The Origin of Species by Means of Natural Selections was published in 1859, he received a lot of violent reactions. In his book, Darwin challenged the Bible’s account of creation and explained that human beings are descended from an ape-like ancestor (Singh). However, Charles Darwin received backlash from many critics. After Darwin's book was published, he obtained many letters criticizing his idea of evolution due to people's religious beliefs. Darwin wasn't only criticized by the church, but also by scientists. He also received letters from scientists such as Adam Sedgwick and St. George Mivart, rejecting Darwin's natural selection hypothesis. Although he received a lot of backlash for his beliefs, he stayed true to his claims. Other world renowned naturalists such as Alfred Russell Wallace developed similar ideas as Darwin, expanding on evolution. To this day, evolution is still taught in many classes and is a theory that most scientists refer to.

Although Darwin’s (1809-1882) work in evolutionary observation might appear radically different from those focused on other areas, the theories he developed from these observation lead to such groundbreaking publishing’s as The Origin of Species. These intern caused an upset within the then accepted norms of philosophy and religion, had a profound impact on the academia, and further

Over one hundred fifty years after Darwin’s theory has been published, the evolution theory is still highly controversial. The idea didn’t go well with the public, Darwin was so embarrassed by the ridicule he received that the swimming-bear passage was removed from later editions of the book (Than). Darwin’s views brought him into fierce conflicts with others who continue to maintain that the account of divine creation contacted within the Bible was correct. According to Than, Darwin’s theory of evolution by natural selection is one of

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?”

In 1837, Charles Darwin was traveling aboard the H.M.S. Beagle in the Eastern Pacific when he stopped on the Galapagos Islands. There, Darwin found a wide array of animals including the Galápagos finches. The differences that he uncovered between these animals sparked Darwin’s interest; he had never before seen nor attempted to understand the similarities and differences inherent within these species. Examining each and uncovering the probable reasons for their distinctions, namely their differing needs for adaptation, Darwin constructed his theory of natural selection. From his observations on the Galapagos Islands, Darwin continued developing his research into eventually what became known as the Origin of Species, published in 1858. In this book, he asserted that these animals and differing species did not just appeared out of thin air, but rather had evolved from other species through the process of natural selection. Yet, his scientific findings were not accepted by the general public when first published, nor long after. Instead, they sparked a great uproar and criticism, since for most people accepted the theory of the Creation, the belief of divine creation, as the way people and species appeared on earth. His findings, so contrary to the then accepted norm of creation, were met with hostility and resentment by many who considered his work

Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found, communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect. Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.

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 universe is too massive to describe in words, and is always expanding, mars could have once held life, and NASA has already discovered other habitable planets. There is no reason to scoff at the notion of alien life, the facts are too numerous, but we always need more. More discoveries and theories to keep the dream alive, that's why people should be more invested in space exploration, problems we have on this planet could have solutions on others. The universe could hold answers to questions we haven't asked, and to those queries we have, it's just a matter of whether or not we’re ready for

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.

Exoplanets exist in a vast array of sizes, in numerous systems, across countless galaxies. This begs the question: is life realistically, even mathematically possible elsewhere? The only answer we have right now is: that we don’t know for certain. The only baseline for life

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.

During the time when Charles Darwin was alive (1809-1882) most of the Western culture believed that the world was created by God and only several thousand years old. They believed that our world was always like it was then. So when Darwin wrote The Origin of Species it shook up both the cultural and scientific views of his time. His views that evolution occurs by natural selection was one of the most radial theories during his time, yet today is widely accepted as a fact among most of the world.
