Science is the study of the structure and behavior of different physical and natural aspects. Scientists study these aspects, observe them thoroughly and experiment before coming to a conclusion. There have been several scientific discoveries and inventions in the past that have proved to be a boon for mankind.
Concepts of Science and Religion
While a logical and systematic approach is followed in the field of science to come up with new ideas and inventions, religion, on the other hand, is purely based on the belief system and faith. In science, a thorough observation, analysis, and experimentation are done to derive a result whereas there is hardly any logic when it comes to religion. Their view of looking at things is thus completely different from one another.
The conflict between Science and Religion
Science and religion are often seen at loggerheads due to their conflicting views on certain things. Sadly, at times these conflicts lead to disturbance in society and cause suffering to the innocent. Here are some of the major conflicts that have occurred between the advocates of religion and the believers of scientific methodologies.
- The Creation of the World
Many conservative Christians believe that God created the world in six days sometime between 4004 and 8000 BCE. On the other hand, the cosmologists state that the universe is as old as around 13.7 billion years and that the Earth emerged around 4.5 billion years ago.
- Earth as the Centre of the Universe
This is one of the most famous conflicts. The Roman Catholic Church regarded Earth as the center of the universe. As per them, the Sun, Moon, stars and other planets revolve around it. The conflict arose when famous Italian astronomer and mathematician, Galileo Galilei discovered the heliocentric system wherein the Sun forms the center of the solar system and the Earth and other planets revolve around it.
Unfortunately, Galileo was condemned as a heretic and put in house arrest for the rest of his life.
- Solar and Lunar Eclipse
One of the earliest conflicts occurred in Iraq. The priests there had told the locals that lunar eclipse was caused because of the restlessness of gods. These were thought to be ominous and aimed at destroying the kings. The conflict occurred when the local astronomers came up with the scientific reason behind the eclipse.
While the astronomers state a strong and logical reason about the occurrence of the solar and lunar eclipse, myths and superstitions surrounding the same still continue in various parts of the world.
- The Evolution of Species
Taking reference from the biblical book of Genesis, the conservative Christians believe that all the species of flora and fauna were created during the six days period when God created the world. The biologists, on the other hand, argue that the various species of plants and animals evolved over a hundred and millions of years via the procedures of natural selection.
Apart from these, there are several other areas wherein scientists and religious advocates have contradictory views. Even though the scientists/ astronomers/ biologists have backing for their theories most people deeply follow the religious views.
It is not only the religious advocates who often raise voice against the scientific methodologies and ideologies, but science has also been criticized by many other sections of society because its inventions are giving way to various social, political, environmental and health issues. Scientific inventions such as nuclear weapons pose a threat to mankind. Besides, the procedures of preparation, as well as the use of most scientifically designed devices, are adding to the pollution, thereby making life difficult for everyone.
