Edwin Hubble's Law

That the universe extended beyond the Milky Way was already widely surmised, and this discovery didn't change much. The revolution came when Hubble compared these newfound distances with the velocities of galaxies, which can be determined by measuring their color spectra. To his surprise, he found the two to be nearly linearly correlated, leading to the conclusion that every galaxy is receding from every other galaxy, and the universe as a whole is expanding.

2. Explain how Edwin Hubble used Cepheid variables to change our view of the structure of the universe.

She is most notable for providing a great deal of compelling evidence, alongside Dr. Kent Ford, that proved Fritz Zwicky’s Theory of the existence of Dark Matter.2 Zwicky stated that individual galaxies within the Coma Cluster were moving so fast that if they were only held by the gravity of its visible mass that it would escape. Since he found no evidence of the cluster falling apart he concluded that there must be something else holding it together that was nearly 10 times that of visible matter, he called this Dark matter.2 While working with Dr. Ford, they began analyzing the light coming from stars in spiral galaxies. They used what is called the “Doppler effect” which states the wavelength shift is proportional to the speed of the light source relative to the observer. This uses the wavelength of light in how it is approaching or moving away from the observer. When a light source moves away from you it presents a red color and when it comes toward you it presents a blue light. After measuring several stars in different parts

The Hubble Constant is the unit of measurement used to describe the expansion of the universe. The Hubble Constant states that the farther a galaxy is away from us, the faster it is moving away from us. Hc = 42 miles/second ÷ 3 million Light Years

At that time, the good view of the cosmos was that the universe consisted entirely of the Milky Way Galaxy. Using the Hooker Telescope at Mt. Wilson, Hubble recognized Cepheid variables, Kind of star that is used to determine the distance from the galaxy, in several spiral nebulae. Including the Andromeda Nebula and Triangulum. His observations proved that these nebulae were much too distant to be part of the Milky Way and were entire galaxies outside our own. This idea had been rejected by many people in the astronomy establishment of the time.

It is not an experience unfamiliar to one of saturated mind to find oneself, stranded at the 2 AM hour, paralyzed by fear for the reality of the insignificance of humanity against an incomprehensibly massive universe. While it perhaps presents itself as scary, the vastness of the universe lends its limitations to more than just our sense of importance, but to our ability to study it as well.

Edwin P. Hubble was born on November 20 1889 in Marshfield, Missouri. His parents were Virginia Lee James and John Powell Hubble who was an insurance executive. He had two sisters and two brothers. In 1900 his family moved to Wheaton, Illinois. As a kid, Edwin was a gifted athlete playing basketball, football, baseball, and was on the track and field team in which he won several awards. In 1906, he set the state high school record for the event High Jump in Illinois. Two of his favourite hobbies were fly fishing and boxing. 1907, he attended the University of Chicago where he studied math and astronomy and became a member of the Kappa Sigma fraternity. The same year, he led the University of Chicago’s basketball team to

Edwin Hubble- One of the most important astronomer there is also the inventor of the Hubble telescope also said to be the man who discovered the cosmos/first to demonstrate the existence of other galaxies had hope to find other things out there in space.

     Edwin Hubble’s curiosity about the universe started at youth and has grown. Without this, he would have no desire to study the stars or galaxies. Hubble’s interest in astronomy at the age of eight. On his eighth birthday party he spent the night with his grandfather star gazing (Freidman 16). When he was twelve years old he would ask his parents to seep outside and look at the stars at midnight with his friend Sam Shelton (18). His grandfather asked Hubble an astronomical question, and Hubble answered it so cleverly that his

It is a commonly known issue in Australia that as a minority group, the people of Indigenous Australian ethnicity have always been treated, or at least perceived, differently to those of non-Indigenous disposition. This can be applied to different contexts such as social, economic, education, or in relation to this essay – legal contexts. Generally, Indigenous Australians face issues such as less opportunity for formal education, less access to sufficient income, more health issues, and higher rates of imprisonment (Steering Committee for the Review of Government Service

As many scientists over the years have been observing, the universe is continuously expanding. The galaxy's velocity is proportional to its distance. Also, that galaxies that are 3 times as far from us move 3 times as fast too! Going back to the expansion part, the universe is just not expanding in one direction, but in every direction there exists! This observation proves that it has taken the equivalent amount of time to move from a common starting position to its current position And since the universe has been continuously expanding there are more and more clusters of galaxies, this. The phenomenon of the galaxies, which are moving farther away from each other, is commonly known as the Red Shift. As light from the distant galaxies come on earth there is a significant increase of space between earth and the galaxy, which leads to wavelengths being stretched.

“The Hubble, has given us nothing less than an ontological awakening, a forceful reckoning with what is the telescope compels the mind to contemplate space and time on a scale just shy of the infinite.” implied Ross Anderson, an engineer. With this one telescope, created by a normal astronomer, scientists and astronomers are able to see space as never seen before. They are able to make mind boggling observations that contemplate space to an infinite scale. Thousands of discoveries about space have been observed through this lense and without the magnitude of high level instruments compiled into this large instrument most of these observations would never have been discovered. As proposed by Floyd E. Bloom a researcher, on izquotes.com, “As

George Lemaitre discovered that the universe was constantly expanding. Then Lemaitre explained that the universe started with a ‘single quantum’ what is now known as the Big Bang theory. Lemaitre discovered that a line exists between a galaxy and it’s redshift, the further away a galaxy is, the greater its light is shifted towards the red end of the spectrum which means there would be a lower frequency. Lemaitre thought that a galaxy’s light is stretched in frequency by the expansion of space itself, the longer the light’s journey, the more the universe has expanded.

In the first place, Edwin Hubble was an astronomer who found important information of the BBT. His findings originated the Big Bang Theory in the first place. (“The Big Bang Theory”, n.d.) In 1929, Edwin Hubble declared that the universe was increasing and that most galaxies were moving away from us. (Redshift and Hubble’s law, n.d.)  This shut down Einstein's theory that the universe was static (“Hubble’s Law”, 2015)Also, “his theory states that the Universe must have been created in this single event which came to be known as the "Big Bang" through expanding at an

In this article about a natural satellite in space, talks about how one of the biggest moon's in our Solar System has an ocean 10 times the depth of the earth's oceans, About 100 kilometers thick. This was found on Jupiter’s largest moon called Ganymede by using The Hubble Telescope. They’ve first noticed that the moon’s surfaces was flooding, presumably caused by bubbling up from the interior of the moon which could be cause by cryovolcanoes (or ice volcano), which was soon discovered that the moon’s surface is made out of a thick crust of ice. They’ve discovered this ocean through The Hubble Telescope by monitoring Ganymede and Jupiter's auroras, to see the change in their magnetic field, and they’ve noticed that the moon’s aurora does not
