Copernicus and the Trail of Galileo

There are two theories about the Solar System. They are the geocentric and heliocentric. The heliocentric theory is said that the sun is stationary and that the planets revolve around it. On the other hand, the geocentric theory was believed b the catholic church which said that the Earth was the center of the universe and the planets and the sun revolved around it because they thought the earth was special. The geocentric theory came first because the church made the followers of the Church believe in the theory. The heliocentric theory came out of the Scientific Revolution ans was the cause Galileo was sent to trail. The heliocentric theory is the correct theory because The sun is stationary and the planets revolve around it.

The trail of Galileo was a famous trail in the Scientific Revolution time period. This trail was in 1633 because Galileo was opposing the Geocentric theory so the Church send him to trail and Galileo was sentenced to House arrest. Galileo believed that the sun was the center of the universe and that the planets revolved around it , which is the heliocentric theory and the Church believed in the geocentric theory which was that the sun was the center of the universe and the other planets revolved around it.

Scientific revolution: the scientific method


The Scientific Method is the strategy we use to solve a theory or question with tests. The scientific method has the following procedures: observation, hypothesis, predictions, and tests. Scientists use the scientific method to conduct tests or experiments by having a theory or a question. Then make a hypothesis and predictions. Next, a scientists has to make tests to see if the hypothesis is correct, if not they had to make another hypothesis and predictions of the test and repeat the procedure if the hypothesis isn't correct. finally conclude the theory or question with an answer.


An example using the Scientific method is the theory of Charles Darwin. He made his hypothesis and predictions. Darwin traveled to find information to proof his theory on evolution. He tested his hypothesis and predictions. Darwin also observed all the prediction. for example finches and the different type of becks can grab different amount of food.

Evolution Vs. Creation

The on going debate on how living organisms came to exist stems from two different theories ; The scientific explanation of Evolution and the religious explanation of Creation. The theory of Evolution was explained by Charles Darwin and other scientists. Charles Darwin's theory of evolution is based on 5 inferences. The inferences are Variation, Completion, Offspring Genetics and Natural Selection. Organisms ass said by Charles Darwin have a common ancestor. There are variations in every population and organisms compete for limited resources such as water, space and food. Organisms are able to produce more offspring that are able to survive. Organisms are able to pass genetic traits on to their offspring. Organisms that have favorable traits are able to survive and reproduce more offspring this is called Natural Selection.

On the other hand the Theory of Creation is seen in the Bible. The bible says That God made the Earth and heaven. Then the day and night. Next the plants and animals. Finally, created man and woman and gave them all the authority to control everything on Earth and to produce more offspring.

In my opinion I believe in both theories, because if creation didn't exist then living organisms wouldn't be able to evolve and change in characteristics and physical change.
