Recommended: Do aliens exist argument essay

Are we alone in the universe? This one is a hard question to answer, but there seems to be an argument that this cannot be so. Firstly, the universe is a huge place, a place that expands every second. It is so big that earth is only a tiny atom in the universe, so we can’t be the only ones alive in all that possibility of space. Secondly, life needs certain things to form; these are called CHNOPS and these are found in other places besides earth. Thirdly, people have reported alien sightings on earth, and this too suggests that we are not alone.

Firstly, universe is expanding every second since the birth of the universe. It was first a tiny spec of high concentrated mass and energy, something triggered it to explode. This explosion was called the Big Bang. This is the start of time, space and matter. This happened 13 billion years ago. The universe is made out of 21% dark matter, 4% normal matter and 74% dark energy and has more than 500 trillion galaxies. Each galaxy typically has more than〖 10 billion〗^2 stars. Each star has more than 1 planet or none sometimes. In 1961, Frank Dr...

  • The Cosmic Perspective Neil Degrasse Tyson Analysis

    In the article The Cosmic Perspective by Neil deGrasse Tyson he examines a range of topics from human life coming from Mars to how our perspective of the universe relates to religion. In the year 2000, a new space show opened at the Hayden Planetarium called Passport to the Universe, which compared the size of people Milky Way and beyond. While a show like this might make someone feel minuscule and insignificant, Tyson says that seeing the size of the universe actually makes him feel more alive not less and gives him a sense of grandeur. I agree with his idea that looking at us as a people in comparison can actually give you a sense of grandeur. However, when I compare myself to the vastness of space, it puts events on Earth in perspective while showing how influential we can be as a people even if we are small.

    A question many ask is, “are we alone in this universe?” Formulas, like The Drake Equation, and arguments, like the Fermi’s paradox, have been proposed help use deduce whether our universe is a biological one. The Drake Equation puts forth high probabilities of extraterrestrial life. However, there are skeptics who believe there is only one planet where life can exist, and this planet is the one that discover us. Whether or not life outside of Earth exist, the exploration of the biological universe is beneficial to humanity’s understanding of our place in the universe.

Although we haven’t encountered any life forms from other galaxies it doesn’t mean there aren’t any. Ted Chiang uses an endangered parrot to show that a possible reason for our great silence is due to or erratic and dangerous nature as humans. However, there are still some instances where humans have connected with other species and created special bonds in the

    The existence of life – Aliens, beyond our planet has been a controversial topic for several centuries, and is a debatable issue even today in the 21st century. What is our topic you may ask? Aliens, Do, Exist. According to theoretical physicist, Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth. This is a bold claim, but there is evidence to support this statement. The evidence we seek is in the many Alien occurrences we have experienced throughout human history.

  • The Probability of Extraterrestrial Existence

    I feel there must be extraterrestrial intelligence. Even if not in our galaxy, in the universe somewhere. Someone once said, "Absence of proof, is not proof of absence." I think he is correct. While we do not know that aliens exist, we do not that they do not exist. Considering the many UFO sightings, most of them are probably conjured, but at least one had to have really happened because the idea is too crazy to be thought of out of nowhere. Some scientists argue that the chances of alien intelligence are slim since the circumstances that produced life were all just strange coincidences, all the same circumstances happening somewhere else is extremely unlikely. I think it is just arrogance to assume we are the only intelligent life in the universe.

    Do aliens exist? For eons, mankind has pondered over this peculiar question and a revealing truth has yet to be answered. However, one thing is known for sure, the discovery of intelligent alien life outside of Earth would provide support to prove and/or disprove fundamental beliefs that have been held for centuries. In any case, the discovery would serve as a cornerstone for humanity to make the quantum leap in understanding the purpose of our existence. Based on numerous examples, it is impossible to deny the existence of extraterrestrial life outside of Earth. Reportings of sightings, ancient civilizations beliefs, and scientific proof from scientists and astronomers are all key factors that contribute to this statement.

From the planets to the stars and out towards the edge of the unknown, we can only see what science provides us with. From this, we know that we are nothing but a tiny planet located in a solar system of millions in a galaxy of many more in the universe.

  • The Multiverse Theory

    1015 Words  | 3 Pages

    The argument suggesting life existing on other Earth-like planets has been present since man first looked into space and questioned his own existence and the existence of others like him. Today there are many theories on the existence of intelligent life elsewhere in the universe, but only one theory goes beyond them and into an even larger realm. The contents of this theory, known as the “multiverse” theory, suggest that humans on Earth live within one universe of many others that reside within a primordial vacuum containing many other universes (Jenkins and Perez). Each of these universes possesses potentially different natural constants and physical laws that govern them differently, thus calling forth some logical questions. First, what is the likelihood such universes even exist, and second, how can we test the constants and laws that still result in the possibility of intelligent life in other universes? Moreover, what implications does this theory have on the ideology that this universe is designed specifically for human beings?

  • Galaxies in Our Universe

    757 Words  | 2 Pages

    The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).

  • Essay On The Big Bang Theory

    533 Words  | 2 Pages

    The big bang theory is an attempt to explain how the world began. The big bang theory begins with what is called a “singularity.” This term is used to describe an area in space which defies all the known laws of physics. Singularities are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that matter is pressed together into an infinite amount of pressure. The dense hot mass of the singularity slowly expanded. This process is called inflation. As the singularity expanded the universe went from dense and hot to cool and expansive. Inflation is still continuing on today which means that the universe is continually expanding.

  • Existence and Beliefs: A Personal Reflection Essay

    The universe exists solely according to each of our own experiences and feelings. For me, the universe was created by God who used evolution to construct us as intelligent, compassionate beings. This is the truth in my eyes, but I know many other people have their own faith that is just as justifiable and true as mine. I know this because everyone bases their feelings about the world around on them on the experiences that each of them had, whether it was growing up with a religion or having an emotional event that caused significant revelations. After watching the Empathic 3 video in class, I had a deep realization that the reason why we are all connected is because we each feel empathy for each other. I believe in reincarnation after death and perhaps we are all one soul with different levels of wisdom in all different moments of time. I believe that by observation a person, you can sense how old their soul is despite their age because I have felt this first-hand. When I was a kid, I used to tell my mom t...
