Why Aliens Do Not Exist

Why Aliens Do Not Exist

Why Aliens Do Not Exist There are several different meanings to the word “alien. ” An alien could be a resident born or belonging to a different country, a foreigner, a person who has been excluded from something, or a creature from outer space (extraterrestrial). For this argument, a creature from outer space would be the appropriate definition. Many believe extraterrestrials do exist. Many even claim to have seen aircrafts belonging to these extraterrestrials. There have been thousands of “sightings” of unidentified flying objects in which many believe do not look like or belong to anything Earthly.

A lot of these sightings have not and can not be explained. Major governments around the globe will not come out and tell the public what they know or if they know anything about these UFO sightings. All of these things have heated up the long debate on whether or not aliens exist, but the debate need not go on any longer because aliens do not exist for three main reasons; interplanetary travel faster than the speed of light is just simply not possible, the closest planets that may possibly contain life are many light years away, and if aliens were really here on Earth, we would have seen them in person by now.

A habitable planet is one capable of supporting life. For a planet to be considered habitable, life on it would have to be carbon-based and would have to use liquid water (Lissauer C11). Here on Earth, carbon cycles between the atmosphere, the oceans, living organisms, fossil fuels, and carbonate rocks. Scientists have been searching for Earth-like planets for a long time. According to an article called Are We Alone by Gregg Easterbrook, Frank Drake held a conference of physicists and astronomers in the year 1960. There he proposed his mathematical equation for predicting whether aliens exist.

The result based on the equation was that there are about a million extraterrestrial civilizations scattered across our galaxy. Many of the scientists in attendance supported this result. “A critical variable in the equation is the number of other planets. In 1960 it was assumed that planets would be prevalent throughout the galaxy. But so far no planet outside this solar system has been detected. ” James Trefil, a physicist at George Mason University, ran through Drake’s equation and estimated that there was only one intelligent civilization in the Milky Way — us.

There have been many cases in which scientists have believed they found habitable planets, but they have not been able to officially confirm whether life is possible on them. For example, astronomers have found a potentially habitable planet, 55 Cancri F, with two suns. This planet adds to the huge speculation list of potential habitable planets. They estimated that it is about 40 light years away. “While 40 light years is pretty close, it’s still over 150,000 years away (Roel 1). ” That is about 1,875 times longer than an average life of eighty years old for a human being!

Even if aliens did exist, they would have to have a pretty good reason for traveling that far. One would think that aliens would want to make contact with us by sending out radio waves before going to all of the trouble of traveling that far. “…any early communication technology like radio waves would be floating around and traveling to other stars for those same thousands and hundreds of years. They should have reached earth by now even before the aliens had (SIX Reasons Why UFOs Don’t Exist 1). ” Earth’s antennas have not picked up any radio waves from any extraterrestrial life.

If aliens existed, then that would mean they got here before the radio waves did and would have had to travel faster than the speed of light to get here. As far as scientists know, that kind of technology is not possible. Faster-than-light travel is impossible because it would take an infinite amount of energy to accelerate to the speed of light. An experiment by a team of Hong Kong scientists was conducted to find out whether faster-than-light travel is possible. They measured the ultimate speed of a photon using controllable wave forms. Hong Kong scientists claim to have proved that a single photon cannot travel faster than the speed of light in a vacuum, making time travel seemingly impossible (Beck 1). ” Because of this experiment, it has been confirmed that traveling faster than the speed of light is not possible. Unless there is some kind of super advanced technology that us human beings have not discovered yet, it is impossible for aliens to travel faster than the speed of light. This is another main reason proving why aliens do not exist.

If one assumes aliens are real and also assumes they have made the long journey to Earth, for the sake of the argument, then humans would have seen these aliens in the flesh by now. Gregg Easterbrook, author of the article Are We Alone, puts this point into perfect perspective. “Enrico Fermi, one of the inventors of the atomic bomb, proposed that the absence of extraterrestrials on Earth is the strongest argument that extraterrestrials do not exist. Indeed, Fermi’s simple question – ‘Where are they? ’ — has become the rallying cry of SETI skeptics within the scientific community.

This question still carries considerable weight. ” Extraterrestrials would physically be among human beings if they really existed. They would have been seen clearly in the flesh by the human naked eye. Instead of physical sightings of extraterrestrials in the flesh, all of the evidence that aliens do exist is either testimonial or is in blurry and unclear pictures of supposed UFO’s. “Sightings” of UFO’s have been happening for centuries. One might be lead to believe that after all of these hundreds of years, aliens would have been seen in the flesh instead of floating over the Earth’s atmosphere for all this time.

The point is, there has not been one single sighting of an extraterrestrial in person after all these centuries and because we have not seen one single alien being in person all the way up to this point, there is no way they exist. Even though the three big reasons why aliens do not exist has been explained for this argument, there are still smaller reasons that add to the fact that there are no other existing alien civilizations other than ours here on Earth. One of those reasons is that governments do not give very much evidence supporting the existence of alien civilization.

In fact, European governments have completely disclosed everything they know about UFO’s. The only evidence most governments give out to the public is testimonial evidence. There has never been any real hard physical evidence. Another reason is that scientists, in a sense, know that aliens can not exist, but they use the ridicule excuse as a cover up to explain why they do not admit UFO’s are real. Scientists are supposedly afraid of the ridicule they would receive if they would happen to admit aliens do exist. On the other hand, scientists lie and cheat to gain fame and fortune for all kinds of research and investigations.

The discovery of UFO’s would make them big and famous, but yet all scientists stay away from it. They do not actually stay away from fame because they are afraid of ridicule. The real reason they stay away from it is because they know it’s a belief system disguised as science. They understand people can believe in anything. Why should any scientist be afraid of ridicule if they can prove aliens do exist? The SETI (the Search for Extraterrestrial Intelligence U. S. government program) is another reason that proves that there is no extraterrestrial life. NASA used to spend millions of dollars to study for signs of alien life in outer space. Why if they have some UFO hotrod parked out in the back of the ‘White House’ would they have spent all this money (Six Reasons Why UFO’s Don’t Exist 1)? ” Lastly, in the 1950s aliens were thought to be among us and had come from within the solar system. They were from Venus, Mars, and the outer moons of Jupiter and Saturn. The proof was out there somehow even though the government was still hiding this information away from the public. Then the United States and Russia started sending probes to explore these planets and found them very inhospitable to life.

All of a sudden these aliens were quietly moved out of the solar system and into other star systems. Today, all aliens travel faster than the speed of light and come from far away. The proof that aliens exist is still supposedly out there, but just further away. All of these reasons make a good case as to why aliens do not exist. However, scientists will continue to search for signs of alien life throughout the universe. They will strive for breakthroughs in research on faster-than-light travel and search for planets habitable to life in hopes of finding an alien civilization.

Many human beings will still continue to believe what they want to believe. The debate on whether aliens exist will live on, but the truth is they do not exist for three main reasons being that the technology for interplanetary travel faster than the speed of light does not exist, the closest planets that are potentially habitable are many light years away, and if aliens really did exist we would have seem them in the flesh by now. “We are alone, period. Perhaps there is no sound of breathing on any other world, no matter how many stars stretch out to the barricade of existence. And there never will be (Easterbrook 1).
