copernicus and trial of galileo

One of the theories of the solar system was the geocentric theory. It was also called the Ptolemaic worldview. The belief in this system was common in ancient Greece. It was commonly accepted at the time. The theory was that the earth was the center of the universe and other planets and stars go around it. It was embraced by Ancient Greek philosophers called Aristotle and Ptolemy. They believed that the Sun,Moon, stars, and naked eye planets revolve around the Earth.
After this time, the geocentric theory was proved wrong. it was proved wrong by heliocentric theory.It proved that the earth wasn't the center of the universe. It proved that the sun was the center of the universe and that all the planets and the stars revolve around the sun. Scientists started to believed this when they started to notice that the sun and the moon were slowly changing their posotions every day. it wasn't until 1,800 years later, in the 16th century, that the Polish mathematician and astronomer Nicolaus Copernicus showed a fully predictive mathematical model of a heliocentric system. Later in time, it was explained and extended by Johannes Kepler.
Many years ago, there was a man who played a big role in the scientist revolution. He was an
Italian physicist, mathematician, astronomer, and philosopher. he was the one who made improvements to the telescope Galileo was put to trial because he published a book of his observations of heliocentrism. The church including the Pope Urban who was the leader, believed in the geocentric theory because they felt that is what the word of God was telling them. Galileo tried to prove to them that his theories he found out through his observations , that his theory was precise and that they were wrong but it was quickly rejected because it was against the word of GOD. He gave up on it because he realized he couldn't win and the court put him in house arrest even thought people wanted to put in in jail and torture him. In the end, he died in his house and many years later the church figured out that he was right and they were wrong and they eventually apologized

Scientific Revolution: The Scientific Method

The scientific method was used to correct or improve a idea or previous knowledge. it was also used to bring forth the truth out of the lies and delusion. in regards to being scientific ,methods of inquiry or the seeking of information by questioning must be based on gathering observable,provable or verifiable information experience or experiment, and measurable evidence that is subject to certain principles of reasoning. scientific methods has to have a good amount of information / data through observations and experimenting. it also needs to have a good hypothesis.
One example of a scientific method of the scientific revolution was during the ancient greeks time, there was a a Greek philosopher called Aristotle. he was a student of Plato and teacher of Alexander the Great . he had a theory that heavy objects fell faster than lighter objects. at the time a lot of people believed him. but this was in till he was proved wrong . a young Italian named Galileo tested his theory. According to legend, he went up to the Leaning Tower of Pisa and dropped stones of different of different size and weight to the ground. He proved that was Aristotle wrong and proved something else through his experimenting. objects of different weights fall at the same speed.

Evolution vs. Creation

Evolution basically is the change of the genetic material in a population of organisms from one generation to the next. One of the things needed for evolution to take place is time. The population needs time to live and to adapt to the enviornment in case it changes. Some organisms in a population last long because they can camouflage. it allows then to avoid predators and give them time to reproduce to extend there population. Reproduction is also important for evolution because not only it makes the population bigger, it allows new combinations of genes that is produced by genetic recombination, which can increase variation between organisms. Adapting also helps because when a organism adapts, it gains new characteristics to survive in the changed or changing environment. which can led to physical changes also.
Creation is refered to religious assumptions based on belief that every thing including mankind,earth and everything in the universe including the universe itself. The people who follows a religion believe that everything was made by a God or a god or just some one with supernatural power. For example, christians believe that every thing was created by God, that there was nothing in the world and he made every thing in the world in seven days. In japanese religion, God Izanagi and Goddess Izanami were married to each other. Izanami could give birth to anything. One day she created the island of Japan. Izanami died when she gave birth to the god of fire from deadly burns during labor. By then she had given birth to 14 islands and 35 gods.So as as you can see, creation goes against science 100%
As a Christian, i believe in what other christians believe in. that the world was made the the one and only God in seven days. I believe in my religion, but also believe in evolution because for the amount of time the earth has been around, the animals who have ancestors that go way back to the beginning had to adapt. Like the cockroach , its believed to go way back till the prehistoric time along with the dinosaurs. Some of the evidence they have is fossils that strongly resemble them. so since there still around today, they had to adapt to there environment to live this long.
