Scientists have had many arguments on how the Earth is really shaped. Some say that the Earth was round rather than a flat plate. It came to mind on how the Earth was really shaped when there were eclipses on the moon. If the Earth were a flat disk, the shape of the moon would be stretched and arched. Also, Aristotle, a Greek philosopher, thought that the Earth was stationary. He believed that the sun, the stars, and the moon orbited around the Earth. A Greek philosopher named Ptolemy made a model predicting the alignment of the galaxy, and the Christian church adopted his model.
Before Galileo and Newton came, most people believed Aristotle ideas about motion. He said that a body was at rest and only move if a force acted upon it, and that a heavy body should fall faster than light one. Galileo proved that those ideas were false. Newton used Galileo's experiment to form his law of motions. Aristotle believed that anybody would stay at rest if it were not driven by a force, but Newton believes that there is no unique way of rest. Besides their differences, Aristotle and Newton believed in absolute time. The speed of light was discovered by Christensen Roemer. He proved that light travels at a quick speed, and that you can measure that speed.
An American astronomer named Edwin Hubble showed the world that our galaxy is not the only galaxy out there. He calculated the distances to nine different galaxies. The Doppler Effect was established which is the relationship between wavelength and speed. Hubble observed other galaxies and their spectra. The discovery that the universe is expanding was the greatest revolution of the twentieth century. Additionally, Einstein introduced an antigravity force that said that space time had a bu...

Albert Einstein, Galileo Galile, and Isaac Newton were the greatest men of all time. Einstein’s efforts for peace took him far. Galileo was responsible for the birth of modern science. It was his work that was to be genius of modern physics. Lastly, Newton was not that nice, but he was a powerful man. All these great scientists paved a way for our humankind.
Our human kind is thrilled to know how our universe was created. All these theories lack observational evidence. The earliest theoretical attempts to describe and explain the universe involved the idea that events and natural things were controlled by spirits. We have found the task of science to be the discovery of laws that will enable us to predict events. Humans are still trying to come up with a theory, but when they find the answer, it would be the ultimate triumph.
Geniuses like Isaac Newton and Albert Einstein and Thomas Edison were not only smart, but they also devised new theories, solved mathematical mysteries, and pioneered new gadgets.
“If I have seen further that others, it is by standing upon the shoulders of giants.” -Sir Isaac Newton. Sir Isaac Newton and Robert Hooke were by far the most brilliant scientist of their day. They individually and collectively made huge contributions to the science of their day. Sir Isaac Newton was Without the work of Sir Isaac Newton and Robert Hooke, the world of science would be no where near where it is today.
Isaac Newton, (1642-1727) was an English scientist and statesman. Although his views were thought to contradict the bible he was the only man of these three which proved his views to be true. He discovered gravity and the laws of motion. He stated that, 'every particle in the universe is attracted to every other particle by a force that is directly related to the product of their masses and inversely related to the squares of the distance between them.
Edwin Hubble supported Georges Lemaitre’s ideas as it fitted in with his own observations. While he were charting the galaxies he discovered that they were moving away from Earth at a high speed and time was expanding in all directions. He was able to track the movement of remote galaxies and other systems due to a phenomena known as Doppler shifts. However Hubble miscalculated and his data calculated that the sun was older than the Universe. Later Allan Sandage recalculated Hubble’s data and proved to the world that the Universe was older than first proposed. Planets, stars and galaxies only make up 4% of the Universe, the remaining 96% is unknown or unexplored territory. According to NASA there is a dark energy that is making the Universe expand and accelerate at a bigger rate than it did years ago . There are many galaxies apart from out Milky Way that are moving further and further away. Scientist like Stephen Hawkins believe that our Universe is just a small part and that many other Universes exist. According to Hawkins we live in a multiverse. He believes that there are more than 100 billion galaxies, each with 100 billion stars.
The first record of the movement of the planets was produced by Nicolaus Copernicus. He proposed that the earth was the center of everything, which the term is called geocentric. Kepler challenged the theory that the sun was the center of the earth and proposed that the sun was the center of everything; this term is referred to as heliocentric. Kepler’s heliocentric theory was accepted by most people and is accepted in today’s society. One of Kepler’s friends was a famous person named Galileo. Galileo is known for improving the design and the magnification of the telescope. With improvement of the telescope Galileo could describe the craters of the moon and the moons of Jupiter. Galileo also created the number for acceleration of all free falling objects as 9.8 meters per second. Galileo’s and Kepler’s theories were not approved by all people. Their theories contradicted verses in the bible, so the protestant church was extremely skeptical of both Galileo and Kepler’s
1 - Concentric theory - 15th century - taught that sun, planets revolved around the earth.
In support of his thesis that the universe spawned from nothing, Krauss points towards the big bang theory. The original theory was that everything was static, but Edwin Hubble proved this invalid, that the universe was actually expanding. Using advances in telescopic technology and previous knowledge of the light from stars, he correctly made this assertion. Using the very same scrutiny, Hubble determined that our Milky Way galaxy was not the only one in the universe. Krauss uses this theory to demonstrate that an expanding universe mean...
In 1905 Einstein published the Annus Mirabilis papers. These papers explained each of his four main theories; the photoelectric effect, Brownian motion, Special Relativity and Matter energy-equivalence. These four works created the foundation for modern day physics and brought a new view to space, time and matter. Brownian motion is the random movement of small particles in either a gas or a liquid caused by collisions with the particles around them. Albert Einstein came up with mathematical equations that allowed him to determine the exact size of atoms. With these equations Einstein essentially provided the first substantial evidence that atoms actually do exist. Einstein’s second paper was on the photoelectric effect. Until Einstein, the photoelectric effect went unsolved. Einstein concluded that when a photon hits a metal surface, the photoelectrons on the metals surface are emitted as certain light frequencies. Thus proving that light has quanta meaning it has packets of energy. This has brought huge technological advancements and has a lot to do with many things that surround us today. Old television used video camera tubes that required the photoelectric effect to charge the screen and transform the image...
The Big Bang Theory is one of the most important, and most discussed topics in cosmology today. As such, it encompasses several smaller components that attempt to explain what happened in the moments after creation, and how the universe we know today came from such a fiery, chaotic universe in the wake of the Big Bang. One major component of the Big Bang theory is nucleosynthesis. We know that several stellar phenomena (including stellar fusion and various types of super novae) are responsible for the formation of all heavy elements up through Plutonium, however, after the advent of the Big Bang theory, we needed a way to explain what types of matter were created to form the earliest stars.!
Powerful mythologies are normative, as Mircea Eliade described, defining for their societies how the world may be ordered. Myths provide the living backdrop on which people may act. In the Christian societies of Europe and America the “origin myth” that defines the divine order that Christians should follow is laid out largely in Genesis, and the worldview expounded within it in some sense provides the baseline from which “scientific” alternatives must deviate, at least within the Europe and America.
Another important individual who drove history was the Italian astronomer and scientist Galileo Galilei. Galileo discovered something so important that it changed the selfish perspective that humans were the center of the universe and led to the growth of human knowledge. Utilizing mathematics and a telescope he had developed, Galileo observed that the planets revolved around the sun and not the Earth. This was a significant discovery because not only did it contradict what the church had taught, it also showed that the universe was not what it seemed. With this truth uncovered, many people began to fascinate over the universe. This triggered people to begin studying space extensively and eventually lead to present day space exploration. Galileo also left a lasting impression upon many great minds, such as Sir Isaac Newton, who used Galileo's research and theories to further his own studies such as the physical laws, and their properties.
Sir Isaac Newton is the man well known for his discoveries around the term, Motion. He came up with three basic ideas, called Newton’s three laws of motion.
Since the dawn of intelligent man, humanity has speculated about the origins of the universe.
The scientist Aristotle (384-322 BCE) developed many important theories which modern day physics is based upon. One of these theories is Aristotle’s theory of motion. Through his research Aristotle attempted to provide explanations as to how objects in our universe moved. While many of his theories have been since proven to be inaccurate, they provided a basis for future theories which eventually lead to our present day understanding of motion.
Science even proves that there was a divine creator present when the world was first designed and when life first appeared on earth.
