Since the early medieval ages, the idea of cosmic pluralism, or the idea that multiple worlds like earth exist with their own forms of life, has been thrown around philosophical and theological. It has only been in the last few centuries that books (like Orson Wells War of the worlds), and television shows like the History Channels ancient aliens, put forward theories and tell stories that
One of the biggest mysteries for the human race isn’t what is on Earth, or even in the solar system, but what is beyond. Although powerful telescopes, such as the Mauna Kea Observatories, can see incredibly far, they’re only able to see roughly 46 billion light years in any one direction, making the diameter of the observable universe, or the part of the universe that humans can observe with telescopes, roughly 92 billion light years. Since the universe as a whole is so vast, scientists are unable to estimate the actual size (Redd, 2013) and possibly will never be able to do so if it continues to expand. In the Milky Way galaxy alone, there are an estimated 8.8 billion stars with habitable Earth-like planets (Borenstein, 2013), which greatly
The adaptive features of animals: i. Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.
Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive. This process is known as natural selection, which explains how Charles Darwin’s theory of evolution can occur.
Adaptations allow deep-sea creatures to survive in extreme environments. There are many different adaptations that allow an animal to survive. The three common adaptations consist of habitat, appearance, and diet. The Giant Squid, Zombie Worm, and the Yeti Crab utilized these adaptations to survive, and without them it would be difficult to nearly impossible to keep their species alive and flourishing. Each one of theses species is suited for its environment and survival tasks through its adaptations.
Even science, at this point, can only postulate what answers these questions may hold. However, as science begins to develop, the possibility of finding answers continues to create a gravitational pull like a planet may. With so many eyes on the field and a lack of scientific proof, literature and movies in the genre of science-fiction, or more commonly known as sci-fi, explores ideas of the future commonly by expressing a widespread fear. These fears can range from a fear of annihilation to fear of loss of control or even simply to a fear of the unknown. The sci-fi movie Europa Report (2013) decided to rise to the challenge of answering the question of what’s out there.
But when the twentieth century was at the gates of new and historical events, that began to change. New discoveries shook the old certainties and paved away for questions about "where the universe came from?". One observation transformed our ideas about the true scale of the universe. It began with a mystery in the sky. By the early part of the twentieth century, it was well known that our solar system lay within a galaxy, the milky way.
Environmental change plays an important role in evolution. When an environmental change occurs, it can be a physical or chemical change. It can also be a gradual process such as the formation of mountains, or it can be a rapid and unexpected change, such as a natural disaster. When changes in organism’s environments occur, they must adapt to their new environment, this can cause ample amounts of selective stress and pressure on organisms, causing some species to eventually die out, while other organisms strive and evolve to be better adapted to this change.
“Where did the universe come from? Why are we here?” What is to become of us? Such questions have traditionally been answered by appeal to the supernatural. From time immemorial, the workings of the natural world have been attributed to supernatural beings (Gods),” (Schick 2013, 432).
Without outside intervention, there is no tale to tell; in other words, there is only the Nothingness that has always remained a possibility in man’s encounter with the Universe. Unlike the preposterous pulp-fiction worlds of Mars and Venus created by Edgar Rice Burroughs, for example, where an energetic evolutionary force has created an elaborate hierarchy of intelligent beasts and beings, Clarke and Kubrick looked to outside intervention to spur the slow, steady state of terrestrial change. If the
The Big Bang Theory, known by scientists as for how the world came to fruition,
The Evolutionism or Creationism Debate The evolutionism-reationism debate has been going on for centuries among christians and scientists. However, creationism is said to have more logical proof of their points being the strongest. According to Charles Darwin, Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
This part of the essay will summarize the main points of naturalism, creationism and existentialism suggested by Baggini. Both pros and cons of the above positions will be discussed and the preferred position will be indicated at the last part.
An organism which does not require water is never discovered. While some organisms require less water than others, e.g., cyanobacteria Chroococcidiopsis, for instance, requires minute quantity of water that biologists even think it may be able to survive on the arid surface of Mars. Every organism that is alive needs water to survive. In fact, without water, life on Earth would never have started. Water is also one of the reasons that there is no life on any other planet in the solar system.
