The possibility of interstellar travel
Many people or even scientists claimed that interstellar travel is impossible. They argue that it may take a spacecraft too much time to accelerate to a speed close to the speed of light. Some people think other stars are too far, and it may take hundreds or thousands of years to reach them. However, as we will show, these arguments don’t rule out the possibility of interstellar travel. In contrast, there are possible method to travel to very far object in a person’s life. We don’t consider some possible but still very unrealistic technologies like twisting spacetime.
Interstellar objects are very far. The closest star except the sun is Proxima, with a distance of 4.27 light years. Many stars have a distance of hundreds or thousands of light years. Some people think it impossible for a spacecraft to reach these stars because any object cannot travel faster than light. 100 years is required for light to reach an object that is 100 light years away, and it will take even more time for a spacecraft to reach the object. However, the argument above doesn’t take relativity into account. There are two different reference frame for us to understand this problem. First, for people live on earth, the time of an astronaut in the spacecraft will slow down in such a high speed. For example, assume that a spacecraft travel at a constant speed of 0.99c, and a star is 42 light years away as seen from the earth. People live on earth think the
For many years humans have been exploring space to discover the unknown and fuel their curious and adventurous nature, but the decision of whether space exploration is worth the cost is strongly debated. Due to various arguments and evidence space exploration is strongly supported is proven to be worth the cost. Some of these reasons include space exploration being able to expand our knowledge and it being able to generate wealth. With these reasons the argument of whether space exploration is worth the risk can be easily decided.
It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in the human mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, pedestrian numbers. So long as every distance within the system of interest is scaled by the same factor, we retain the meaningful information about relative distances between objects.
Since humans started populating the Earth, exploration has always been on their minds. Before the 19th century, expansion was kept within Earth’s atmosphere, but as of the 20th-century exploration has expanded onto the whole galaxy. In 1961, Russia sent their first human outside of the Earth’s atmosphere, thus initiating the space race. The space race’s first goal was to get a human from and to the moon, alive and well nurtured. Unlike pre-19th century expansion, this exploration would not bring back any goods or materialistic value. Even though the Space Race may have helped those who lived in Russia and America, to others it was seen as a waste of money because of the lack of materialistic value; money that could be spent otherwise. Their motivation fueled
However, due to the technological evolution and the industrial and mechanical revolution, sky was not an unsurpassable limit anymore, but what lied beyond that sure was. By the time the first telescope was made, space’s conquest has been a goal that first world’s nations have been trying to fulfill. Simultaneously though to that goal’s fulfillment, a question popped up that created numerous new theories and propagandas. Are we alone in this vast universe? And if we are not, how does it look or behave those who coexist with us?
When discussing ideas like travelling through space time one must maintain an understanding of how the causal chain functions. The causal chain is a series of
Interstellar, a movie about space, time and family, was made in 2014. The movie features Matthew McConaughey as he journeys through space to find a suitable replacement for their blight infested Earth. Throughout their space trek, they are able to overcome obstacles and solve problems through scientific analysis and logical thinking. Although Interstellar was made for entertainment and not educational purposes, the thorough research put into the movie allows for the average moviegoer to understand the plot and further increase his or her knowledge of the science of space.
The word “impossible” has been a controversial topic discussed for years by people who just explain why there is nothing more we can do. In the book, Physics of the Impossible, Michio Kaku takes multiple ideas and concepts from recent books or movies and he discusses how each of them could or could not exist in the future. Kaku is a theoretical physicist who attended Harvard after winning a scholarship there (preface xi). His passion for science began young in life when he entered and won a science fair, which was his inspiration (preface xi).
The mention of Einstein’s theory of relativity and mention of the already known effects one civilisation can have on another, do not prove that pre-historic space travel occurred on Earth. Rather, they only provide an indication that it could be possible by use of explanation by mere scenario, as they only explain why space travel is possible. Furthermore, the argument also includes the pseudoscientific mark of irrefutable hypothesis, as there is no way of testing or falsifying the claims. Moreover, the argument also appeals to myths by attempting to explain unexplained ancient phenomenon, such as the Pyramids being
Voyager 1, launched over 35 years ago, reached the barrier between our solar system and the vast unexplored interstellar space beyond in August 2012. Imagine the stories that probe could tell! As the Titan-Centaur rocket boosters rattle to life beneath it the intrepid robot takes off for a record-breaking 40-year trip alone in space, going places no man-made thing has gone before. There will be tales of Jupiter and Saturn’s fascinating moons and atmospheres, the amazing discoveries concerning solar and galactic wind at the edge of the heliosphere, solar intensity and power production. Voyager 1 will explain basics of gravity assists, launching from Earth in the
Although I have seen many movies which have an incredible space mission, but it cannot compare with Interstellar. Matthew McConaughey, who play Interstellar as an astronaut named Cooper, he lives in the world that has been facing with plant disease, which is going to be human extinction. So that he has to save humanity and his daughter alive. One day, he got messages that a binary format sent from something that he did not know exactly what it came from and who sent it? But, the messages are the NASA command center location. When he had arrived at NASA, he met doctor bran, who is physicist told him, NASA has the plan to form a team of explorers travels through a wormhole in space an attempt to find another place which humanity able to
Time travel has been debated for years by philosophers and non-philosophers alike. While the possibility of time travel is intriguing and alluring, I do not believe its portrayal in today’s media is plausible. In this paper, I will argue that time travel, particularly back in time, is not possible in our current world and universe.
Mankind has always been fascinated with exploring the unknown. From sailing to distant lands to someday setting foot on other planets, the spirit of exploration is the same. Bur now with the current economic situation and the high cost of sending people to space, NASA is being looked at as a way to free up some much needed funds. Although, there is many problems here on planet Earth that need addressing, the benefits of space exploration far out weight the disadvantages. Space exploration has given us more advanced technology, advances in the medical field, and a boost to the economy and these facts cannot be disputed.
The mysterious vastness beyond Earth has allured many scientists to explore and contribute much of their effort to the understanding of space. Although humans have been looking up at space for thousands of years, the physical exploration of this frontier has been only going on for the past few decades. Our current understanding of space is unparalleled to any time before in our history, but we still only know a small fraction of what there is to learn. Governments around the world spend about $40 billion dollars a year (Rockefeller, 2010) hoping to undertake tasks such as “human exploration of the solar system” to discovering the origins of life itself (Tatarewicz, 2009, p. 531). Recently, the private sector has also shown interest in space exploration in order to engage in profitable activities such as harnessing minerals from asteroids. Although it is easy to debate about the benefits and negatives of space exploration in its entirety, it is simpler focus on one aspect of it - the direct effect it has to those down on Earth. Rather than trying to decide whether or not going to other planets is worth it, this paper will argue about the value of the terrestrial benefits of space exploration. It is an important topic to think about as programs such as space exploration change lives and help acquire knowledge. Despite the large costs associated with space exploration, the multitude of discoveries in the past few decades has greatly improved daily life on Earth, the jobs the
This peer-reviewed journal article talks about the positive consequences of developments in future space exploration in scientific perspective. The author states the development of future space exploration by using resources from the solar system will produce varies beneficial results, such as space tourism, asteroid resources, and so on. The main beneficiary among all the others is science. Supported by space resources, the growth of space economy can provide the cost of building scientific instruments, outposts, and infrastructures in space. Improvement in scientific technology leads to further discoveries and knowledge. Which shows the symbiotic relationship existed between science and space resources.
Space is huge. The universe is bigger than we can get it. The universe is large to the point that stars bigger than our Sun or even entire systems look like little pinpoints of light since they are so far away.
