The Universe : Are We Alone?

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

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

Does life exist on other planets besides Earth? Has extraterrestrial life visited Earth recently or in our distant past? The notion of extraterrestrial life is a very intriguing subject possibly for as long as mankind has looked into the vast heavens gazing at the stars. Can one say that life on Earth was done by Mother Nature which some call evolution? Is life on Earth the result of creation or alteration by a higher power or being? Some people do believe that other forms of life except those on Earth do exist. Others consider it false because there is no absolute proof beyond doubts. There have been countless occurrences by individuals around the world of either being contacted or abducted by alien life forms. Many unofficial accounts describe the Earth as being visited by one or more alien species. These various alien species that possibly visited Earth may be interested in observing the development of the human species.

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration such as how close the planet is to its star (in the case of our solar system, the sun), how long the water and organic materials existed there, and the size and mass of the planet. One must not confuse habitable with inhabited. The term

We live in a universe that is about 46 billion light years old. In a world, as massive as ours there must be some form of extraterrestrial life out in the galaxy. For thousands of years ancient peoples, such as the Greeks, have wondered the same question. Are we alone? As our technology advances, things such as videos and photographs are surfacing of people claiming to see such alien life. Whether it is an unidentified flying object, or if it’s from someone claiming to see an actual alien, there are thousands of people that believe they have seen proof. Some also claim that the government is hiding things behind our backs, like the Roswell UFO incident for example. Though many people refuse to believe in the existence of alien life forms until they see evidence, the fact that multitudes of people have eye-witness accounts, the improbability that we are alone, and the idea that we have thought of aliens so long, bring forth the evidence that proves something is out there.

Are we alone? Are there people around us? Has anyone heard about aliens? Are they real? Can you answer all of those questions, if not, then just keep reading. In my opinion aliens do exist and there are plenty of evidence to prove they exist.

Aliens and life beyond earth has been a mystery for a long time. Many people and scientist have been looking for life outside of Earth, or just floating in the sky trying to get video of it. For all of human history we have been looking for extraterrestrial life, and these are the major events of finding, debunking, and moving forward to life on earth

James Green discusses in his speech the possibility of there being life beyond earth. Green starts off with a quote that is used in a lot of movies, books and television shows, “Is there life beyond earth in our solar system?” He follows this initial quote with one by Carl Sagan, an American astronomer, “It takes extraordinary evidence for extraordinary claims.” It is important for Green to use these two quotes as attention getters. He hooks the listener with his works and we begin to think if there really is life in our solar system then just on earth.

Most astronomers and scientists seem firmly convinced of this fact. Although there is not any direct (or even indirect) evidence to support these claims that other sentient life is sharing the universe with us. However, this lack of evidence showing that extraterrestrial life forms exist is not proof that they do not exist. It just does not seem logical that our planet is the only place where life and intelligence could have developed. The odds are billions against life of some form being unique to the Earth only. The Earth is unimportant in the grand scale of things in the galaxy. By this I am referring to its' size and position in the universe. In fact, the American Association for the Advancement of Science suggests that the true question that we should be

Potential extinction that the tardigrade may face would most likely hinge on the fact that it takes time for them to enter into cryobiosis. While in its active metabolic state they are much more vulnerable to all outside conditions. Even in a more vulnerable state it would most likely take another mass extinction event for tardigrade to become extinct, and even then those that were at the time in cryobiosis would likely still survive. The only definitive way to kill the water bear would be if there was no longer any water on earth. While we know they can stay in stasis for decades we do not know if there comes a time that they will no longer be viable and be able to

To begin with, there is more than one sun out there in space, and a sun can contain about one million planets in space. Scientists have discovered about one thousand planets orbiting distant stars. They have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets.

The idea of extraterrestrials existing and having visited Earth is a long shot, which made scientist Enrico Fermi question their existence, and that is how the Fermi Paradox was created. Enrico Fermi questioned the idea that since the Universe is billions of years old and billions of light years in diameter, extraterrestrials must exist somewhere and have visited Earth. Scientifically, there isn’t enough evidence to prove that extraterrestrials exist or have existed throughout our universe, but this hasn’t stopped millions or even billions of human beings from believing in them. There are countless of possible solutions to the Fermi Paradox, but all are hypothetical. The first possible and most popular solution to the Fermi Paradox is that

Water bears, scientifically known as tardigrades, are puffy, microscopic creatures. The name “water bear” comes from zoologist J.A.E. Goeze in 1773 because of its strange similarity to bears (Bordenstein 2017). All tardigrades are noted as aquatic because they require a film of water to exchange gas (Lindahl and Balser 1999). Tardigrades have been found everywhere, therefore, they need to adapt to every kind of environment. Tardigrades can survive below freezing temperatures as well as above boiling temperatures.

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,

Many people who live on Earth are close minded to what is really out there in the universe. They cannot even begin to fathom the vastness of it and how Earth is just a tiny little speck compared to everything else out there. From the planets to the stars and out towards the edge of the unknown, we can only see what science provides us with. From this, we know that we are nothing but a tiny planet located in a solar system of millions in a galaxy of many more in the universe.
