The mass of a Star determined the Star's development and time of death. The most of the Star's have age from one billion to ten billion years.The Solar System has a planet where there is a life. The Solar System locates in the Milky Way and the Solar System has 26,000 light years from the center of the Milky Way. The Solar System has known to be life a unique planet. This planet is the Earth.
69). In Book I, Nicolaus strongly argues against the geocentric theory, which states that the Earth is at the center of our solar system. Claudius Ptolemy, a Greek Geographer and Astronomer, came up with this theory. Everyone later on came to believe the geocentric theory. Controversy augmented when Nicolaus evolved the heliocentric theory, which was later included in Book I of De Revolutionibus Orbium Coelestium.
Eddie Cohen The first astronomers had a great influence on what we now know as modern Astronomy. A majority of astronomers made massive advances for their time. Ptomely, Nicolaus Copernicus, Tycho Brahe, and Galileo all were known for their advanced thinking. Their theories were so advanced for their time, that it typically got them in trouble with either the government or the church. One of the most influential astronomers and geographers of all time was Claudius Ptolemy.
There has to be a something that is uncaused. Just like newton 's law so is the cosmological argument, there has to be a first cause that uncaused. But, some scientists believe that the universe has existed forever. Yet in 1929 Edwin Hubble, an astronomer at Caltech, made a discovery that proves that the universe did not exist forever. “He measured the redshifts of a number of distant galaxies.
The Lunar Day Animation Questions: a. How much time passes between one high tide and the next? The tides are created by the gravitational pull between the moon and the Earth, so the time difference between the tides depends on how long a lunar day is. A lunar day is 24 hours and fifty minutes and in one lunar day the Earth rotates through two tidal bulges. The time between one high tide and the next is twelve hours and twenty five minutes.
This sun is 432,288 miles across and the galaxy is supposedly 6,213,711,922 miles wide. It takes 250,000,000 light years for the sun to orbit the galaxy. There are approximately 100 billion different solar systems in the Milky Way. Our dolor system is 25,000 light years away from the center of our galaxy. Our galaxy is so big we have only gone 19.5 kilometers from home.
To begin with, Copernicus is by far one of the most important in the Scientific Revolution because he basically started it off. Before Copernicus, Ptolemy believed that the Earth was the center of the universe and all of the planets including the sun and the moon revolved around it. Moreover, according to Copernicus, what appeared to be the movement of the sun and the fixed stars around the earth was really explained by the daily rotation of the earth on it’s axis and the journey of the earth around the sun each year. Copernicus made some research and he found out that Ptolemy was incorrect. Copernicus contradicted Ptolemy’s ideas about the earth being the center of the universe because he made some research and found out that the sun was actually the center of the universe.
In October 1923 Hubble spotted what he first believed was a nova star flaring up in the M31 nebula. After examining several photos of the area, he realized that it was a Cepheid star. Using Shapley’s method, Hubble placed M31 a million light-years away. Discovering this, Hubble realized that there are more galaxies other than ours. This discovery is often referred to as the discovery of the universe and cosmos.
In the year of 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect. This model added to the advancement of quantum mechanics. c. Reason for listening: This topic is important because people often only think about Einstein’s theory of general relativity, but he offered so much more. d. Credibility: For my informative speech, I have conducted extensive research on the scientific contributions of Albert Einstein. e. Thesis Statement: People view Einstein work as just if he has only contributed a few things to sciences and physics, but he did a greater amount then the majority of people know.
“We all travel in time. During the last year, I 've moved forward one year and so have you,” (Spaceplace.Nasa.gov). The question that is much more likely being asked is can you speed up time, or put it in reverse. The answer is humans truly don 't know. Physicists theorize that reverse time travel could be impossible, but think that it could be very possible to travel forward.
