The theory that life can possibly exist on another planet is an exciting idea. The search for extraterrestrial life has been looked over countless times. So many people believe that there is life beyond planet earth, many others have realistic expectations to this theory. They simply just believe that this theory has no evidence to be prove that there is any extra-terrestrial intelligence anywhere in the universe.
A vast number of people still consider this question especially scientists and astronomers who spend a lifetime trying to prove or disprove the idea that extra-terrestrial does exist in an outside universe. Throughout time technology has advanced and many scientist are able to study this question more efficiently. The theory of life beyond earth has been concentrated on attempts to receive wavelength signals. Wave length signals are “the distance between identical points in the adjacent cycles of a waveform signal propagated in space or a long wire. “ (Dictionary.com) While the people on earth lead themselves on to believe the possibility of extraterrestrial life, many microbiologist astronomers and zoologist have been focusing on the environments that creatures have adapted to in order to survive. Microorganisms such as tardigrade usually found in moss can live in temperatures that vary from -400 to 400 degrees Fahrenheit, and don’t require much water to live. Many scientist believe that these microorganisms have mastered living in environments on other planets in our solar system. The conditions that these microorganisms live in on a daily basis bring many scientist to conclude that there may very well be extra-terrestrial life elsewhere.

..., represents the fraction of planets with life that actually go on to develop intelligent life. An even more crucial piece fc, represents the fraction of civilizations that develops a technology, and enables it to release detectable signs of their existence into space. L of course represents the length of time that these signal signs are released into space. Although this equation is used by scientists many have said that the N variable portion of the equation is useless because it is impossible for the equation to physically detect the number of outside civilizations based on the infinite length of our galaxies alone. Realistically speaking this equation has only been proven to work effectively as a great tool to trigger our curiosity about the universe around us. It does not actually aid us in identifying outside life species, like it was originally believed.
Fermi’s paradox supports this claim because theoretically there should be species capable of interstellar travel due to the age of 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
With more and more planets being discovered everyday isn’t it a little narcissistic of us to believe that we are the only planet that can sustain life. With movies like Star Wars, and Star Trek the thought of extraterrestrials are becoming more mainstream. However there are still many people who don’t believe.
Today we live in a world where many human beings move from one place to another. We live in a world where individuals in most cases move away or even escape their own country in order to live a better life than they had before. Though in the United States of America those who move in this country are called in such an unusual way. Those who move into this country, where I and million of U.S citizens live, are called the word “alien”, which according to the Oxford English Dictionary is someone who is “born in, or owing allegiance to, a foreign country.” When using the word “alien”, it mainly directs to immigrants from foreign countries in the world. When using the word “alien”, many individuals might immediately think of an alien who lives in
“I think humans will reach Mars, and I would like to see it happen in my lifetime” was said by Buzz Aldrin, a NASA astronaut. The former American aeronaut from Montclair, New Jersey believes that since Mars does exist, it is waiting to be reached by humans. When this would happen, he says that the human race would “evolve into a two-planet species.” Present day Mars has a lot of canyons, mountains and volcanoes. Even though the surface is Mars is very old, scientists learned about different younger rift valleys, plains, hills and ridges. According to recent reports, there were lakes and rivers, along with an ocean billions of years ago. The low temperatures on the planet cause there to be polar ice caps and frozen water present. Scientists continue to notice several discoveries on the planet that lead them to think there was once life on the planet. Different clues have scientists wanting to find out about even more. Many scientists in the past few centuries have been curious if life on Mars is possible or if it has ever been before.
Even though, there is much debate about the purpose of the aliens, there is more agreement about the types of aliens that are reported. Examples are the ‘tall whites’, the ‘grays’, the ‘humanoids’, and the ‘reptilians’. The ‘tall whites’, aren’t always as tall as some of the people say. They actually assume to grow as they mature. Growing so much that eventually they out grow their bodies and eventually die. The ‘grays’ are assumed to be led by the ‘reptilians’, they are small and gray with big metallic looking eyes. The ‘humanoids’ are almost exactly like us. They behave in a similar matter, they look like a cross breed of a gray and a human. But they are tall, pale skinned, and they have blonde hair and blue eyes. The ‘reptilians’ are sot
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.
One of the most controversial arguments of this day, are aliens real or they just a hoax. We all always wonder if really do exist, and to the people who don't believe that they exist I will try my best to change your minds a little that there is living life forms on planets or galaxies. In fact, Mars actually has ice or water scattered around the Martian planet. The famous hidden and heavily guarded place in the U.S is the Nevada Test and Training Range and Groom Lake, aka “Area 51”, has been in suspicion of keeping top secret things from the Roswell UFO Incident that happened in 1947. Well we all know the CIA will snag those things up and hide them, instead of showing the curious world if we are really the only ones that occupy this plant or even this whole universe. With great numbers of stars covering our solar system or universe, life is possible. It doesn't take a rocket scientist to know if other planets went through the same stages that our earth is going through in this heavily planet and star populated universe.
Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.
Intelligent life outside of Earth is one of the most debated topics in The United States of America. There are plenty of shows on television about it and supposedly there has been thousands of sightings all throughout America. Our government is thought of to have encountered and held extraterrestrials. Area 51 is where everyone theorizes that we hold and run tests on aliens, even though there is little evidence. There are also ancient stories told about “gods” coming down and doing inhuman things. In cave paintings you can find UFOs in the pictures, even back then they somehow knew of these flying objects. Most people do not want to recognize that our universe is so vast it would be more likely that there is intelligent life out there than there is not. It is possible that the general population is afraid to acknowledge Aliens’ existence because they cannot imagine a species being more advanced and smarter than us. Another reason people fail to recognize them is because the media has made these “creatures” very far fetched with
For thousands of years, it was thought that the Earth was the center of the universe. Today, even a young child knows that idea is false. As knowledge increases, so does the understanding that the Earth is not as unique as previously thought. There are billions of other planets out there, and odds are that a significant amount are comparable to Earth. If a planet as insignificant as Earth can develop a vast and diverse number of organisms, it is logical to assume that life could take root somewhere else in the universe.
Trillions of habitable planets, those that can sustain liquid water, exists in the universe. From looking at the number of habitable planets that exist, there should be other life forms in the universe and out of these life forms, there should be intelligent civilizations. When looking for alien civilizations, researchers look at the planetary bodies within our local group. Everything outside the local group is unreachable because the universe is always expanding.1 “If only 0.1% of those planets harbored life, there would be 1 million planets with life in the Milky Way.
The findings in this book could easily be compared to real findings, throughout history we have been looking at finding proof for existence of life out in the universe and we have found several meteorites throughout times. Though they are not as significant as the discovery in the book where they are found during presidential elections and with fossils on it, but today when people are looking in space and saying our future lies there; reading the book has made everything just more interesting and exciting. "If this discovery is confirmed, it will surely be one of the most stunning insights into our universe that science has ever uncovered. Its implications are as far-reaching and awe-inspiring as can be imagined. Even as it promises answer to some of our oldest questions, it poses still others even more fundamental"
Do you believe in aliens? If you had asked me this three weeks ago I would have laughed at this childish question. In the early 2000’s people used to believe in extraterrestrial life, but in my lifetime all science disproved the idea that we would ever see other planets, or the planet’s inhabitants. Our minds couldn't fathom a machine to enable us to see into our universe that far. The lack of hardcore evidence resulted in our ultimate refusal to accept that other life could exist and this eventually led to our ultimate demise.
While this idea may seem straight out of a science fiction movie, some evidence suggests that an extraterrestrial origin of life may not be such impossible idea.
Life is everywhere, but was it always? There are so many theories about how life began on Earth. Evolution, electricity, panspermia, but we may never know the real hypothesis. Because we are all in the dark, we have to come to our own conclusions. Some are understood scientifically, others are indifferent opinions and everything in between. The chilly start theory is the idea that Earth was covered with ice containing compounds that interacted with eachother. Scientists have found the chilly start to be a reason for life because, ice is a catalyst, the earth was once frozen, and the scientific possibility.
