Life in a Distance Universe
What is life in terms of a planet? What is life in terms of a galaxy? What is life in terms of a solar system? More importantly does some type of “life” exist in another universe somewhere? In order to answer this timeless question one must first answer what is life. From there once the definition of “life” is established, and then we can research, investigate, and come to a conclusion of whether life exists in another universe somewhere. It must be said that we might have to come to a philosophical conclusion as one could never fully research every planet as there is an infinite numbers of planets. In this paper the main argument will be made physically and theoretically for the case of life in another universe.
Many humans on planet Earth tend to believe that life is described as tiny microscopic material called bacteria. In terms of an astronomer speaking one might describe

The main problem is the distance. For example “at a distance of about 2.5 million light years, the Andromeda galaxy (also known as NGC 224 and M31) is the nearest galaxy to the Earth apart from smaller companion galaxies such as the Magellanic Clouds.” (http://www.bbc.co.uk/) 2.5 millions light years is hard to comprend in earth time. The simple fact is once again we kinda know of ways to travel very fast theoretically. These ideas just not have been developed yet.
Another argument for the existence of life on other planets is the phenomenon of extremophiles! These orgasims are a type of living being that can thrive under high temperature and pressure. Some can even survive without oxygen. Lots of these extremophiles are found at the bottom of the ocean near hydrothermal vents.(http://oceanservice.noaa.gov/) And the best part is we are finding new extremophiles. It wouldn be crazy to think that we actually might be able to find this type of organism on some other planet or
In the last hundred years we have made enormous progress in studying not our galaxy but ones billions of light-years away. Only a few hundred years ago our world seemed so big that there were areas of the world that had never been charted and people believed that the Earth was flat (and yes for some reason a few people still believe that today). If we continue to make progress at thus rate the universe will actually begin to seem smaller because of how much more we might know.
Carl Woese’s (1990) groundbreaking paper categorised the Tree of Life into three domains for the first time– Archaea, Eubacteria and Eukarya. Before this, Archaea were known as Archaebacteria due to their prokaryotic, single-celled appearance similar to bacteria. However, Woese analysed 16S ribosomal RNA from all three groups and discovered there were differences of such significance in the sequences, for example between positions 180 and 197, that Archaea should be classified as their own domain. The three domains are believed to have separated from one common ancestor, with Eubacteria and Archaea diverging 3.8 billion years ago and Archaea separating from Eukarya 2.8 billion years ago. This means that, despite their appearance, Archaea share more similarities with eukaryotes, such as 33 identical ribosomal proteins, than with bacteria.

An underlying theme present throughout the series is the possibility that our existence is not the only one. According to current theories in physics, it is entirely possible that our universe is just one of many universes f...
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.
As stated by Prescott, Harley and Klein (1990) microbiology is the study of organisms that are usually too small to be seen with the naked eye.
The Andromeda is part of the Local Group of galaxies. The Andromeda galaxy is the closest full size galaxy to the Milky Way. The Andromeda Galaxy is about four times bigger than the moon in the sky. Andromeda contains around one trillion stars. The Andromeda Galaxy is also the only galaxy noticeable to the naked eye in the Northern Hemisphere. The Andromeda Galaxy is the Milky Way's larget galactic acquaintance and is on course for a collision in the fututre.
The galaxies that are not inside of us are really moving away and the ones that are farther away are moving away the fastest and we don't know why.That also means that even if you are in another galaxy . the other galaxies are moving. The universe has no center; however, the galaxies are not moving through space, they are moving in space, because space is also moving. A amazing astronomer Edwin Hubble made the theory that in 1925 and was the first who could actually prove that the universe is moving away from us. It is most likely possible that the universe will last forever, or it may be destroyed and crushed out by existence in a reverse version of the Big Bang scenario. The universe was created by one the biggest events of the Big Bang Theory. Albert Einstein once stated “that the most incomprehensible thing about the universe is that it is comprehensible”. “he also said to have deep faith that the principles of the universe will both be beautiful and simple.” People have thought about how the big bang theory happened or not happened, and for a lot of years there were a lot stronger debates between those supporting it and those who favored theory of the universe was created by god, even some people believe that the universe was just there and no one created it , in which the universe was eternal and unchanging.The universe just might die out because of the sun, we are currently bein...
Recently, two probes were sent back and they made it to Mars. They landed on the South Polar Caps of Mars. That is where NASA plans to find water. After landing on Mars, the probes extracted water like crystals from the surface of Mars. They found that there was a small amount of water in the crystals, which means that there is a strong chance that life, was on Mars at one time.
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.
It is a single-celled organism that is not visible to the human eye, which means it can only be seen with a microscope. Bacteria are classified as Prokaryotes. They make their own food from the sunlight and can absorb food from the materials that they live on.
A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass. Galaxies also contain billions upon billions of stars and their diameter can range from 1,500 to 300,000 light years. That’s huge! The Milky Way, the galaxy in which we live in, is one of about 170 billion galaxies in the observable universe. Our Sun is one of the billions of stars in our galaxy, and our eight planets revolve around this star in only a tiny part of our galaxy. “The Earth’s solar system is believed to exist very close to the Galaxy’s galactic plane, due to the fact that the Milky Way essentially divides the night sky into two virtually equal hemispheres” ("All About the Milky"). It definitely makes people second guess the fact of there being life on other planets.
This is more time consuming than interplanetary travel and also needs a higher technological level that has not yet been come across. This kind of travel may be essential for the survival of our race because in around 5.4 billion years, our Earth and all other planets in our solar system, will become too near to the Sun causing all life forms to be destroyed, due to overheating. From this information, we can conclude that we will need to spend extensive periods of time focused on interstellar travel, to travel to other stars that may have Earth-like planets in its orbit. Interstellar could cost upwards of $174 trillion and require nearly 40 years of development. This would be very daring and since there isn’t that much money in our current system, we would have to print
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.
