Introduction: The population density of the world is 57.376 people per square kilometer of the earth’s surface (). This includes all of the world’s oceans and Antarctica, which are uninhabitable. Additionally, climate change and diminishing natural resources are putting increased strain on the world economies. A clear solution to the problems is space exploration. While still in the explorative stage, making the step to colonization has massive implications.
The “Rare Earth hypothesis” argues that the occurrence and development of those complex multi-cellular lives including highly intelligent human beings on the earth, require an extremely uncommon combination of, diverse geological, biological, chemical, meteorological and astrophysical factors, events and circumstances. This book report aims to summarize the main ideas in each chapter, in accordance with their importance and length. There is also a short conclusion at the end of the report. Content Summary Chapter one - Why Life Might Be Widespread in the Universe Extreme heat, extreme cold, extreme pressure, darkness and toxic-waste waters
Scientists have been busy analyzing the bounty of data and are busy creating new missions to find out more about comets. One of the reasons scientists want to study comets is that the icy bodies on comets could have delivered the organics and all molecules needed for life when they ran into the solar system . Past comet missions and ground-based telescopes have seen dozens of molecules on comets, including organics. Today scientists are not doing anything more with the Rosetta Mission but, a year later NASA created a mission called the “Deep impact”. The Deep impact mission is similar to the rosetta’s because scientists launched a probe into space that was designed to study the interior composition of comet Tempel 1 by releasing an impactor into the comet.
This will help scientists accomplish their goal of colonizing Mars. Through this mission, scientists will learn more about the land on Mars. As stated earlier, the rocks can show the elements that exist of Mars. The soil can inform people if the ground is healthy for planting crops. The samples of the atmosphere can tell what the air is made of.
O. Glenn Smith (former manager of shuttle systems engineering at NASA’s Johnson Space Center) said, “If we send nine crews to Mars it will cost around 1.5 trillion euros.” However the NASA administrator recently said, ”If we were to pioneer Mars it will cost around 2 trillion euros.” The question is, who will pay for all this money. Will it be all the space administrations or should all the countries give an amount of money to the mission? But why do we have to spent so much money on the mission to Mars when we have bigger problems on Earth. We have global warming to fix, unemployment, lack of education, poverty, etc. and why not use it for those important
Hundreds of years ago, people used to believe that the earth was flat, but with the research and technology, we were able to find out that it is a perfect sphere. Aliens run along those same lines. Even with all the technology today, there is still no definite answer if we are alone in this massive universe or not. There is so much controversy weather or not aliens exist. Over the past few decades the ideas of aliens has morphed into a craze, that one has to ask themselves, “what is an alien?” With “aliens” being in Hollywood movies and roller coaster rides, what do we actually consider to be aliens?
Finally, NASA is National Aeronautics and Space Administration of the United States of America. “We would never have got a chance to go outside and look at the Earth if it had not been for space exploration and NASA” (James Lovelock, BSc). Humankind have always wanted to discover universe since their inception, from Yuri Gagarin to Neil Armstrong, from the Apollo missions to the Hubble Space Telescope. Moreover, space travel is accelerating the process of increasing wisdom for people to explain mysteries of prehistoric Earth. For example, what’s the age of the Earth and how did the first living specie came to life.
There is an overwhelming amount of support for theories on the origin of life. Although each theory differs to one another, all proposed theories imply that life has evolved from single-celled microorganisms to the complex multicellular life forms that have existed over millions of years. The first hypothesis I am evaluating is the Panspermia hypothesis. Panspermia, from Ancient Greek is defined as (pan) meaning ‘all’, and (sperma) meaning ‘seeds’. It is the hypothesis that states life exists all throughout the Universe, and life is propagated throughout space from location to location via meteoroids, comets (Wickramasinghe, 2011), and planetoids (Rampelotto, 2010).
How did the Earth originate? Was there any supernatural being behind the creation of the Earth? There have been many claims and theories on how the Earth originated such as “The Big Bang Theory” and “The Nebular Theory” meanwhile there were two theories and claims that caused a debate for almost more than a century which is Evolutionism and Creationism. The Theory of Evolution is false because it could not prove any scientific evidence unlike Creationism that base all of it facts on the Bible, that has been proven scientifically and historically accurate. The Evolution Theory is one of them most common ways to contradict Creationism as it tries to prove that the world is over 4.5 billion years, Humans evolved from apes by natural selections, and etc., meanwhile Creationism it states that there was an ever-existing Creator who created the universe with nothing.
