How does light speed affect the universe? What about our everyday lives? In the History Channel documentary, “The Universe – Light Speed”, what light speed is and how it affects the universe helps explain how important it is for not only learning the history of our Solar System but the universe itself. How light speed affects stars we see from Earth, the significance of redshift, light horizon and how it affects our glimpse into space, and how ideas are being formulated to traverse space are key points in this documentary. A light year is six trillion miles of which light travels to Earth in a year. The documentary highlights this as the importance for the unit of a light year in which Michelle Thaller notes that one light year is equal …show more content…
There hasn’t been enough time for light to travel more than that” (The Universe – Light Speed). Light horizon is the sphere around Earth in which any direction only allows us to see 13 ½ billion light years. This seems to reflect, in my opinion of that the, “Earth seems to be in the center of the celestial sphere only because it is where we are located as we look out into space… the celestial sphere is a useful illusion, because it allows us to map the sky as seen from Earth” (Bennett, 28) but instead of constellations, the light horizon deals with the ‘horizon’ of Earth’s view into the farthest view into space. This was new and surprising to me because I found out that there’s an obstruction to the speed of light of which beyond is radiation left over from the Big Bang. The Inflation theory about the Big Bang to explain cosmic microwave background radiation was completely new to me and the first I’ve heard of it as well as how it relates to space constantly expanding. I found that space expands faster than the speed of light making is exclusion to the law of the speed of light was extremely attention-grabbing since I find the beginnings of the universe to be something I love to learn …show more content…
I thoroughly enjoyed learning new theories such as inflation theory in relation to the Big Bang as well as what is being done to further our exploration of space. Overall, I felt the documentary taught me numerous facts in relation to astronomy an understanding not only how light speed affects Earth but the universe as a
In Alan Lightman’s, “Our Place in the Universe,” he describes his experiences in the Greek Isles explaining how meek it made him feel to be surrounded by the vast ocean with no land in sight except a small strip of brown in the distance. Great thinkers throughout history, have been exploring the visible variety of shapes, colors, and sizes, though the greatest of these are size, from the smallest atom to gargantuan stars. These massive differences in size change the way we view ourselves in the universe. (470) Garth Illingworth, from the University of California, has studied galaxies more than 13 billion light years away from us.
I really enjoyed this video. It's crazy the amount of informaton that gets packed into a three minute video. I think the cartoon and music that accompanies it helps because you're being entertained as well as informed. I think it's easier for me to remember a fun fact from the video versus reading a whole chapter from a book.
The Big Bang theory is a theory that states that the universe originated as a single mass, which subsequently exploded. The entire universe was once all in a hot and dense ball, but about 20 million years ago, it exploded. This explosion hurled material all over the place and all mater and space was created at that point in time. The gas that was hurled out cooled and became our stellar system. A red shift is a shift towards longer wavelengths of celestial objects. An example of this is the "Doppler shift." Doppler shift is what makes a car sound lower-pitched as it moves further away. As it turns out, a special version of this everyday life effect applies to light as well. If an astronomical object is moving away from the Earth, its light will be shifted to longer (red) wavelengths. This is significant because this theory indicates the speed of recession of galaxies and the distances between galaxies.
But what really resolves the paradox is the same expansion. If the universe is expanding is that it is not infinite. It is not in either space or time, therefore could not be considered but a finite number of spherical shells. Finitude is key. It is true that all of the shells together provide brilliance, but only in the amount enough to let the night as it is ... at

Through all the impacts of Einstein’s relativity on our modern lives, techniques and even our minds discussed above, so we can see how important Einstein’s relativity is to us and how much we have gained. And the great ideas from it will continuously challenge human mind and the arguments around it shall improve our science.
The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person's day-to-day life since we travel at speeds much slower than light speed. For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth. Einstein also
Greene continues with his explanations of the special theory of relativity.Chapter 3: Of Warps and Ripples Green begins the chapter by describing "Newton's View of Gravity" and continues by discussing the incompatibility of Newtonian Gravity and Special Relativity. The author also talks about how Einstein discovered the link between acceleration and the warping of space and time. Greene also discuses the basic aspects of General Relativity. He later points out how the two theories of relativity effect black holes, the big bang, and the expansion of space.Chapter 4: Microscopic Weirdness This chapter describes, in detail, the workings of quantum mechanics.
Overall we can get a pretty good insight on how or Solar System was formed, yes there are still certain aspects of it that are hard to make sense of, as well as debates over which theory is correct, such as Core Accretion vs. Disk Instability, but overall I feel it is pretty amazing what we have learned about the nature of system and look forward to future discoveries.
The theory was first proposed in the 1930s, based on Edwin Hubble's discovery that distant galaxies are receding. Hubble measured the distances to a large number of galaxies (based on the observed brightness of certain stars within them), and compared these distances with their electromagnetic spectra. As it turned out, more distant galaxies had the features in their spectra (spectral lines) shifted to lower frequencies in a linear manner: that is, more distant galaxies exhibit greater redshifts. The only known mechanism for generating a spectral shift is the Doppler effect, which means that distant galaxies are receding from us.
In 1905, Albert Einstein wrote his paper on the special theory of relativity (Prosper). This theory has the reputation as being so exotic that few people can understand it. On the contrary, special relativity is simply a system of kinematics and dynamics, based on a set of postulates that is different from those of classical mec...
Special relativity is a theory that has been accepted by physics as a theory relating to the relationship between space and time. This theory is really important to physics, and all physics teacher such as yourself because special relativity explains the observed fact that the speed of light stays and remains constant regardless of the direction or velocity of its motion. Special relativity now plays an important role in astronomical observation. Special relativity is more precisely about speed. To be even more precisely this speed deals with 299,792,458 ms-1, which is the speed of light, or the rate at which light travels (in meters) per one second.
Although I was not doing an article on black holes, I decided to watch the following documentary, merely because it was related to the cosmos.
...ein’s Theory of Relativity radically altered our perspective of the universe. It profoundly impacted the scientific community and has had an everlasting effect on science itself. All of the properties of his theories define and shape the world around us and without them we would have a negligible understanding of our universe. Albert Einstein once said “Any intelligent fool can make things bigger and more complex... It takes a touch of genius - and a lot of courage to move in the opposite direction.” This is exactly what he did when the first thoughts of Relativity popped into his head in a patent office in Switzerland so many years ago.
