Earth is small. Many people find it hard to believe, but when one thinks of earth in its context, amongst billions of galaxies, stars, planets, and an infinite universe, earth is a mere grain of sand on the beach that is space. With this in mind, one may, quite understandably, find it hard to believe that earth is the only planet that sustains life. With today’s advanced technology and science, extensive evidence has been found suggesting a great likelihood of life on other planets. The discovery
culture and in science but belief in extraterrestrial intelligence goes back into ancient times. Extraterrestrial life is defined as life that does not originate from Earth. With the fascination of aliens among human, many became theorist. They believe that extraterrestrials with superior knowledge of science and engineering landed on Earth thousands of years ago sharing their expertise with early civilizations which forever changed the course of human history (Ancient Aliens). An example of this is Stone-hedge
co-workers an interesting question, “where is everybody”. (Howell, 2014) By which he meant, since there are over a million planets which are proficient enough to support life and possibly some sort of intelligent species, so how come no one has visited earth? This became known as The Fermi Paradox, which came from his surname and two Greek words, para meaning contrary and Doxa meaning opinion, about a 100 years ago. (Webb 2002) A paradox arises when you set undisputable evidence and then a certain conclusion
“Did you know the Bible talks about a great cube-shaped spaceship coming down to Earth?” Is this talking about UFOs? (Graves 12) To begin, this paper is on UFOs, the appearances of extraterrestrial spacecraft; also, the criteria to be one. Why extraterrestrial rockets are perceived to be undeniably real, legitimate, things. Why Flying saucers are perceived to be not tangible, or legitimate things. Finally, why the media glamorizes UFOs. UFO’s will forever be a controversy because of media glamorization
thing is known for sure, the discovery of intelligent alien life outside of Earth would provide support to prove and/or disprove fundamental beliefs that have been held for centuries. In any case, the discovery would serve as a cornerstone for humanity to make the quantum leap in understanding the purpose of our existence. Based on numerous examples, it is impossible to deny the existence of extraterrestrial life outside of Earth. Reportings of sightings, ancient civilizations beliefs, and scientific
State of Research on the "Snowball Earth Hypothesis" The "Snowball Earth Hypothesis" also known as the "Varangia glaciation" is a hypothesis presented in 2001 by Geologist Paul Hoffman. (Wikipedia, 2002) The hypothesis purposes that 540 million years ago during the Neoproterozic, a meter thick of ice covered the oceans and glaciers the continents for 100 million years. Albedo; when ice and snow reflect solar radiation into space, in absents of greenhouse gases, which don't exist within
Transport- The issue of transportation and the environment is somewhat of a paradox. Transportation conveys certain socioeconomic benefits, but transportation is also effecting environmental systems. Positively, transportation supports the increasing need of mobility for passengers and freight, while negatively, transport is tied to motorizations, congestion on transport lines, and the growing lists of environmental externalities. Since the Industrial Age, humans have been rapidly changing their
Generally, as figure 1 shown that the Strengths for this supply chain is good for short run production and hard make mistake. It could avoid the lack of materials and make materials mixed together. However, the Weaknesses for this supply chain is complex which are much labor spending and low work efficiency, especially that new staff needs spending long time to adapt to the job. Certainly, X1 also knows the disadvantages for their supply chain and makes some special change for the disadvantages and
article “Rare Earth Plant Ready, But in a Glut,” by Keith Bradsher it is mentioned the rare earth metals this company will be producing can be found in many cell phones, flat screen televisions, computer hard drives, and wind turbines that are used in the United States today. If this company is not opened it will cut down a fifth of the rare earth metal being mined and it will cause the cost of these rare earth metals to increase. There are many benefits to the refinery mentioned in “Rare Earth Plant
Thank heaven for small favors. Although chances of being hit by a meteorite are slim, it’s estimated that 200 tons of cosmic debris falls to Earth every single day. It rains down in the form of interplanetary dust particles, micrometeorites and chunks of rock. Scientists estimate that some 24,000 stones ranging from just a few grams to many kilograms strike the Earth every year. That’s a bombardment rate of about 40 meteorites per square kilometer over a period of a million years. That’s a lot of meteorites
Rare earth elements allow for the conveniences shared by modern society. It is the critical components that have made the advancements in technology possible. Its versatility expands thought different media that include: renewable energy, geographic information systems, national security, missile guidance, computer technology, hybrid vehicles, plastics, medical technology and more. All population throughout the world use it regardless if they know it or not. The mining and process of rare earths
that he was talking about extraterrestrial intelligence [1]. If life arises fairly commonly, as Fermi believed, it follows that there should be advanced civilizations with the desire to visit and colonize Earth close enough to do so. However, there is no incontrovertible evidence of aliens on Earth, either now or in the past. This is called the Fermi Paradox. The lack of observational evidence for extraterrestrial intelligence is known as the ‘Great Silence.’[13] Giuseppe Cocconi and Philip Morrison
life and exactly where Earth is located (Gammon). If even one of these planets were to develop intelligent life, it should eventually, like life on Earth, develop radio technology. One star system in particular called Gliese 581 has been getting a lot of attention because this star has multiple earth-like planets in its habitable zone. This star is about twenty-two light years away; a relatively short distance on the cosmic scale, and on August 28, 2009, a message from Earth was sent to the foreign
are eight major planets and their satellites. There are many other small planets, asteroids and comets. Large planets are arranged in order of distance from the Sun as follows: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (Pic.1). The furthermost two planets can only be seen from Earth through a telescope. All others can be seen as more or less bright circles of light and were known to people since ancient times. Pluto used to be considered a planet but was recently demoted from
100,000 years ago, a morphologically diverse group of hominids occupied Earth, unlike now, when only one hominid species exists. By approximately 30,000 years ago, these diverse hominids had evolved into morphologically similar, anatomically modern humans. Within the scientific community, there are two main hypotheses as the how and where this evolution occured: the Out of Africa hypothesis and the Multi-regional hypothesis. Evidence like fossils and mitochondrial DNA research may help scientists
dominated planet earth. What were dinosaurs like? How did they survive? How did they become extinct? These are some of the many questions to which answers are being sought. Dinosaurs were one of the largest creatures to ever walk the earth and one of the mysterious creatures too, how they survived and how they became extinct in a flash has been a mystery. One of the many theories associated with dinosaur extinction is an asteroid collision with earth. The Extraterrestrial Impact Hypothesis Approximately
“I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years… We know where to look. We know how to look” ~Ellen Stofan, NASA Chief Scientist (Wall). First off, there are many different beliefs about alien life. Science, history, and eyewitnesses can prove alien existence. However, skeptics have many examples to why alien life does not exist. There are many examples of the media’s role in making alien’s
Approximately 65 million years ago, about two-thirds of all species on Earth, including dinosaurs, became extinct in one of the planet’s largest mass extinction events. There are many theories in investigating what could have caused the majority of species being ruled out. It had to have been from a catastrophic asteroid that lead to major climate change. With the research Luis Alvarez made trying to prove his hypothesis it supports that an asteroid key have been the key trigger. What caused the
In probability theory, The Birthday Paradox serves as a proposal that in a room of twenty-three people, there is a 50% chance that two or more people within that room share the same birthdate. The legendary source of this paradox claims to be discovered and first practiced by Richard von Mises, who posed the theory in 1939, However, the first practicing of The Birthday Paradox is, in all originality, Harold Davenport, who discovered this theory in 1927, making it the earliest discovery of this paradox
of years ago, including the Pyramids of Giza, the Stonehenge, and the Moái Heads of Easter Island (von Däniken, 1968, p. 42). Branching off this theory is the Hypothesis of Creation, which states that humans evolve by genetic mutation, by being either descendants as genetic hybrids of proto-humans and extraterrestrials, who landed on Earth hundreds of thousands of years ago (Burns, 2011). They also believe the majority of creation myths are true, however all Gods, Goddesses, deities, and other primordial
