General relativity

“You cannot teach a man anything; you can only help him find it within himself.” Galileo Galilei made Mathematics and philosophy his profession, against his fathers thoughts that he should go into medicine. He emerged as the scientist who discovered four of jupiters moons. Without Galileo, we probably wouldn't have known that the speed an object falls is not proportional to its weight. Galileo was the oldest of Vincenzo Galileis children. He was sent to the university of piza to study…

Cosmos episode 13, “Unafraid of the dark”, begins by talking about the vast amount of scrolls and information that was kept in the library of Alexandria. Many of the books and scrolls were lost when the mob attacked and destroyed the library. This is shocking because of all the history of Ancient times that he's been lost due to the destruction of these books. Although we lost many discoveries, we as humans continue to learn new information about the universe. This begins the discovery of…

Black holes were, an amazing star that everyone wants to know more information about. Black holes can be dangerous, but all depends on how big the star was inside. Black holes form in, an astonishing way, and will effect the space around you. Black holes are extinct stars that explodes into a black hole. Also, Black holes have layers, named, an event horizon. Which, means when the force of gravity is barely sufficient amount to bring light back, and stop from light being put in the black…

Henrietta Leavitt and Stephen Hawking are similar in a variety of different ways. Both Hawking and Leavitt have contributed a great deal to science. Stephen Hawking had discovered that radiation can escape black holes, and Leavitt had discovered the period-luminosity relationship as well as being fundamental in defining the size of the universe. According to the article on Henrietta Leavitt, “Before Leavitt established the period-luminosity relationship, astronomers could determine cosmic…

Using the most the most comprehensive telescope ever created astronomers have found that the universe is slowly dying. By looking at a lot of data, 200,000 galaxies in 21 wavelengths, they have found out that our universe was producing two times the amount of energy 2 billion years ago, in comparison to today. Eventually our universe with be cold, empty, darkness, but we do not have to worry because scientists suspect that our sun will burn out long before our universe does. The area of…

Space is a huge sea of unknown. We are simply specks of dust, trying to figure out the behaviors of giants. Thus it is apparent that the specks can not know much. For now. One of the biggest mysteries is the expansion of the universe; in the 1990s, we knew that theoretically, our ever-expanding universe was slowing down due to gravity, and that it would eventually collapse or keep expanding, just slower as time went on. However, thanks to the Hubble Space Telescope, we now know that to be dead…

was challenged. As Albert Einstein, a German theoretical-physicist, introduced his theory of relativity, time became another phenomenon and mostly likely, acquired more definitions. In addition, Einstein’s suspicion not only changed the studies of science and physics but even art and literature. Pericles Lewis explains in his Cambridge Introduction to Modernism that Albert Einstein’s theory of relativity transformed the modernist conception of time’s linear progression into the notion…

PACE Speech The problem I researched for this experiment was to see if the weight of a ball affects the speed that ball in travel at when shot or thrown. While researching this I found out that many different sports involve arm strength to throw an object far or at high speeds and many athletes don’t have enough arm strength or maybe don’t have much at all, but for every sport there is always a workout plan to increase what is needed. To increase your arm strength, the weight of a ball is a…

Over 104 years ago, on August 7th, 1912, an Austrian scientist named Victor Hess changed the Astronomy and Physics world forever when he discovered cosmic rays through a strange experiment that took place in a hot air balloon. Cosmic rays are high-energy, subatomic particles that appear outside the Earth’s atmosphere. These rays are known to strike to down on Earth, which may seem dangerous but even very energetic primary rays crash into the Earth’s atmosphere and they basically never make it to…

The results from the 3 Hubble diagrams vary in accuracy, this is measured by the R2 value which in other terms means the distribution of the data in relation to the fitted line of regression. The diagrams are also all measured by using apparent magnitude which is the measure of brightness as viewed from the earth and does not take into consideration distance which can mean results are not as accurate in comparison to absolute magnitude. Absolute magnitude is measured the magnitude of the star…
