Earth is a planet is made up of a mixture of oxygen, nitrogen, carbon dioxide and several other gaseous elements that have created and sustained life as we know it. The universe is a vast space made of matter that varies from the smallest cosmic particle to a massive galaxy. Within one of billions of galaxies is home to planet earth, which is one of 7 planets in the Milky Way Galaxy, all orbiting a star. Based on what human life is conscious of, Earth is the only residence of intelligent life in the universe. Could planet Earth be the only planet able to sustain intelligent life or are there other planets with similar chemical make-up to do so? Or could it be that there are other elements unknown to humans that can create and sustain …show more content…
A massive explosion occurred which lead to a growth and expansion. During this expansion gases were released which then formed galaxies, stars, planets, rock bodies, etc. This occurrence is referred to as the big bang theory. Based on Nature, the international weekly journal of science, Aliens might have existed during the Universe’s infancy years. Calculations infer that liquid water could have formed on rocky planets just 15 million years after the Big Bang. An astrophysicist at Harvard University in Cambridge, Massachusetts, Abraham Loeb, recognized that during the times of the early Universe, energy required to keep water liquid could have come from the afterglow of the Big Bang, instead of from host stars. The temperature of this radiation is now 2.7 kelvin. Based on Loeb’s calculations on arXiv preprint server this month, during the time of the beginning of the universe around 15 million years ago, the temperature would have been 300 kelvin.
Loeb infers that rocky planets could have existed in parts of the Universe where there is dense matter which leads to the formation and development of large short-lived stars. Stars would then have enriched these areas with denser elements needed to create planets. It is said there was a habitable age of 2 million or 3 million years where all rocky planets were able to uphold liquid water, regardless distance from a star. The Universe was at a
There have been various studies, predictions, and theories related to the evolution of the universe. It is an important topic that makes everyone wonder how it all started. It took centuries to finally come to a conclusion that the big bang was the start of the universe. The big bang theory took ages to become a valid model that was accepted by scientists. This model is so far, the most accepted model that validates all the discoveries of major cosmologists and astronomers such as Tycho Brahe, Nicholas Copernicus, Albert Einstein, and many more. The big bang was essentially the beginning of our galaxy including the sun, our eight planets and moons. The start of the big bang is unimaginable. It all started off as an extremely hot element that
First of all, there are so many stars and planets in our universe, at least some of them must have had life at one point. As stated in a YouTube video by Kurzgesagt, "There
Earth is the perfect habitable planet on our solar system right now. For it has right distance from the Sun in which it gets a perfect temperature. It has a magnetic field that protects the planet form the harmful radiation. Earth is also kept warm by an insulating atmosphere, and it possessed the perfect chemical ingredients that is necessary for life
Asteroids and comets are the keys to the formation of life on Earth. According to scientists, comet impacts could have most likely caused amino acids to combine and form the building blocks of life. Chances are that there are comets in other planetary systems that could be doing the same thing right now. It seems impossible for Earth to be the only planet, out of billions, to have life.
already existed about 10 billion years earlier, and after the “Big Bang”? Four and a half
My answer is CHNOPS or carbon, hydrogen, nitrogen, oxygen, phosphorus ,and sulfur. These elements that are listed is the base or structure for each living organism on earth. Carbon is the most favorable structure because it has a rich chemistry. The chemical structure of the carbon atom lets it bond with other elements(including itself) in different ways. This ability to bond with elements with ease is why there are so many creatures on earth. Which is why the study of molecules that contain carbon is called organic chemistry. Out of the six elements listed earlier there are three of them are are crucial to create life. Hydrogen, oxygen, and carbon have a lot of abundance throughout the universe. Shouldn’t this abundance of elements be able to create life in the universe. Yes and No! This should have created life because the six elements should have created life without a problem. Unless, the planet’s ecosystem is not habitable, too hot, cold, or there weren’t enough elements to create a structure. But! Do not worry, there are still some potential in other elements that can also create life. However, most life on earth is mostly carbon based and these elements that can potentially create life would not be carbon based. These other elements can create life if met with the right
The universe was created about 13.5 billion years ago by a huge explosion called the Big Bang. When this occurred, every particle and substance that makes up our universe was created and sent out into the vast vacuum we call space. Once in space, the products from the explosion started to react with each other; creating stars, planets, and light in the process. The Big Bang was essential for the creation of our universe because it created all of the particles that can be found our universe.
article, the elements that supports life was available for many years. This provides evidence to the
In the first second after the universe started, the temperature which was surrounding was around 5.5 billion Celsius. The cosmos had a wide selection of important particles like protons, neutrons and electrons. These either decade or joined as the universe cooled. The electrons
13.7 billion Years ago the big bang occurred and generated all the stars and planets we now know as “space” over time many planets took form after creating many elements that are essential for life to survive such as Hydrogen and Oxygen. 9.1 billion years passed and a planet known as earth started to form from an exploded solar nebula and this explosion created so much energy that it created a red hot planet that the proceeded to cool and created a thin layer of “earth” also known as crust. After 1 billion years of the earth rapidly heating and cooling life first appeared as the form of bacteria such as Prokaryotes that soon evolved into multi cell organisms such as Primitive metazoans after millions of years many processes of Evolution occurred such as Mutations and Natural selection.
Also in The Big Bang Theory, gravity was created by a tiny imbalance in the beginning of creation. Gravity pulled the gases in the universe together and they began to clump. Hydrogen is a simple gas and when heated at 10 million degrees it will shine and provide warmth. Hydrogen began to fuse by a process called nuclear fusion creating a denser element known as
To juxtapose this argument made by the REH, the next key factor is something called the “habitable zone.” The habitable zone is defined as a region within which Earth-like planets might possess the moderate environmental conditions for advanced life to form (von Bloh). Many of these new planets discovered are gas giants with atmospheres too turbulent to support life, so these planets’ habitable zone is said to be “low or nonexistent.” The existence of Earth-like planets, however, is just as common as the existence of these extreme planets. Traits of the habitable zone, such as a carbon-silicate cycle, solar luminosity, and plate tectonics, were analyzed for 200 different possible Earth-like planets in Franck, von Bloh, and Bounama’s research.
The six most abundant elements of life are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Carbon is the most important element because it is found in the atmosphere and all living matter. All living matter on Earth is made up of organic molecules. Organic molecules are formed of carbon atoms, which bond to other carbon atoms , forming complex structures. The complex structure then bonds to other atoms found in essential elements. Without carbon as a backbone, the molecule would break apart. All living things on Earth need carbon to live, grow, and reproduce.
Thirteen billion years ago a supernova accord and created our solar system. Also, planet earth is four billion years old. The calculated life span of earth’s habitable zone is seven-point seventy-nine billion years. With these calculations, astronomers know that earth doesn 't have much time in space terms the earth has roughly about three point twenty-five billion years left until it is unstable for life to flourish. In these years, scientists need to find a habitable planet that can support life and must have a great amount of fresh water. After scientists find that out. They will then need to find out how to get seven point one
Life is an amazing and seemingly rare phenomenon. With the materials necessary and the process that had to take place in a certain order, at certain times, it really is a wonder that we are here. What is even more impressive is that we have managed to evolve past single-celled organisms, and into intelligent life forms. With our increased intelligence, there coincides an increased number of questions that need answers. Does other life exist? What do planets need to support life? Where do we go from here? Throughout this paper, I hope to answer these questions, or at least provide some evidence as to what we know so far. The focus will mainly be on the different types of habitable zones, what special resources and properties are required for a potentially habitable planet within one of these zones, and what this all means.
