According to astronomers from NASA, they estimated that the Big Bang happened between 12 and 14 billion years ago. But how much do we know about the universe after many decades later? In 1959, an institute named SETI (Search for Extra Terrestrial Intelligence) started a project about the universe with opportunity and curiosity. They researched and questioned, "Is there an intelligent life in the universe?" Then in 1961, an astronomer and astrophysicist, Frank Drake conducted an equation called the Drake Equation. Him and his colleagues

R* = The rate of formation of stars suitable for the development of intelligent life. fp = The fraction of those stars with planetary systems. ne = The number of planets, per solar system, with an environment suitable for life. fl = The fraction of suitable planets on which life actually appears. fi = The fraction of life bearing planets on which intelligent life …show more content…
In many of scientific works, if the work can be tested and can have a final result, we tends to believe to in the work. But within this Drake Equation, there is no right or wrong answer or can even test out if there is an answer. From my perspective, it is not accurate to believe in. Also in my opinion, this is just an attempt of humans’ ability to communicate with other intelligent life in the galaxy. "Intelligent life" means if there is possible lives similar to humans out in the Milky Way. Personally, I am trying to figure out what I am going to eat for dinner today, why should I go even further about what's going to happen in the future for civilizations? In the past, I watched from movies and learned different lessons about living in the moment. We never know when will be our last day here on earth. I feel like we shouldn't care about how long the civilization will last because what is important is you are living and giving it all on what's going on
There is a cultural assumption that there are many alien civilizations in the universe. However, what do we really know about extraterrestrial life? With recent findings of water on Mars and the discovery of Trappist-1, there could be hope for extraterrestrial life out in the universe. Even though the water on Mars is frozen under the polar ice caps and Trappist-1 could be far from finding any alien life, there are still many articles supporting the research and looking forward to finding additional news. In the article “Could the TRAPPSIT-1 worlds harbor alien life?’ written by Liz Fuller-Wright, she reports the announcement of astronomers that they found a miniature solar system of seven Earth-sized planets. Furthermore, the argument is effective towards bright individuals because it makes one think about what it will be if there was actually life outside of Earth.
The biological universe is the idea that our solar system contains life other than ourselves. 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 to help 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 discovers us.
We are also over concerned with now compared to the future which I believe to be more important . The world is to caught up in todays tinkerings to think about the end effects.
Edwin Hubble supported Georges Lemaitre’s ideas as it fitted in with his own observations. While he were charting the galaxies he discovered that they were moving away from Earth at a high speed and time was expanding in all directions. He was able to track the movement of remote galaxies and other systems due to a phenomena known as Doppler shifts. However Hubble miscalculated and his data calculated that the sun was older than the Universe. Later Allan Sandage recalculated Hubble’s data and proved to the world that the Universe was older than first proposed. Planets, stars and galaxies only make up 4% of the Universe, the remaining 96% is unknown or unexplored territory. According to NASA there is a dark energy that is making the Universe expand and accelerate at a bigger rate than it did years ago . There are many galaxies apart from out Milky Way that are moving further and further away. Scientist like Stephen Hawkins believe that our Universe is just a small part and that many other Universes exist. According to Hawkins we live in a multiverse. He believes that there are more than 100 billion galaxies, each with 100 billion stars.
Biological factors are related to the sexuality and development in the sexual awareness. During puberty, the young person may not be able to distinguish between sexual and aggressive urges. This would result in sexual aggression that has the outcome of leading to social offense. Drake was introduced to pornography at this critical time in his life. It was during this period that his inclination to sexual offense began to become apparent. He was struggling with the adolescent sex issues while being introduced to sexual indulgence. This contributed much to his confusion and subsequent involvement in the sex matters. Low self-esteem, impulsivity, poor interpersonal skill and poor social behavior aggravated the depth
Since the beginning of human fascination with outer space, the question “Is there life on other planets?” has existed and has waited to be answered. Early astronomers looking to find life on other planets were brutally punished by the Catholic Church. For years, people saw these astronomers as heretics for going against the church and undesirable, but today there might be evidence that supports these astronomers. Today, we find that people are still split between believing in alien life or not. People devoted to a religion tend to disagree with the possibility of life anywhere but Earth as it goes against their beliefs. However, with the increase of realistic movies about aliens and very convincing theories, many young people are beginning to believe that life on other planets does not seem so radical after all. Each day, scientists find more and more predictive evidence that leads most of them to believe that there is life on other planets.
The universe, a vast, ever-expanding space full of mystery, just waiting to be discovered. With the mystery comes speculation; a multitude of researchers focus on one question, are there extraterrestrials out there? While highly controversial, scientists with the help of SETI have proved that this is possible. In order to be prepared for the possible ETs, researchers at SETI work constantly to find answers. Because of the growing research that Extraterrestrial Intelligence is possible, SETI, a credible organization, should receive funding from the government to continue their research.
In conclusion, not one of Percival Lowell’s theories was ever right. However, he left behind a legacy for future space pioneers, as well as being a symbol of hope. He has also left behind a legacy for the public, which has never seemed to have gotten rid of the notion that there is life on Mars.

Frank Drake, an American astronomer made an equation to find the probability of finding aliens in our galaxy. The probability of humans finding extraterrestrial intelligence in our galaxy equals Nfpnef1fifcfL, where N equals the number of stars in the Milky Way, fp equals the fraction of those stars having planets, ne equals the number of those planets that can support life, f1 equals the number of those planets on which life arises, fi equals the fraction of those planets on which intelligent life evolves, fc equals the fraction of those planets where intelligent life developed into a technologically advanced civilization and fL equals the fraction of time a technical civilization lasts. Drake's equation is beautiful, meaningless mathematics. It does not come close to solving the question of the existence of extraterrestrials because it has so many variables that we cannot imagine what they stand for.
THE POWER OF THE MOMENT: The ability to stay in the present is a virtue. Most people are always living either in the past or in the future. So they are either worrying about the past, worrying about the past pains, the past results, the past failures, past relationships, past struggles, or they are ruminating about the future fears, the future impossibilities, the future achievements, future possibilities. Worrying about the past or future would not benefit you as you are putting yourself in a position of disadvantage.
One of the most common unanswered questions scientists find themselves asking is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947, the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs, such as The X-Files, and films (Mars Attacks, Independence Day, and the Men in Black films to name but a few). Scientists have come up with many new ideas and ways of trying to either prove or disprove the existence of life elsewhere.
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?
Even though we know a great amount more than the astronomers in the past, there is still an even larger amount we do not know about the universe to this day. Even our own solar system contains many questions yet to be answered. Some of these include the possibility of a planet beyond Pluto (Planet X), the means by which the system was created, and even the possibility of a sister star to the Sun named Nemesis. Another astronomical mystery is the creation of the universe. In time, many questions will be answered but some will always remain. Astronomy is something that will never be completely understood.
“Don’t worry if your theory doesn’t agree with the observations, because they are probably wrong.’ But if your theory does not agree with the 2nd law of thermodynamics then it is in serious trouble”.
