For centuries, scientists have engaged in research that has increased our understanding of nature and how natural forces work to create and sustain the world and universe we see today. The purpose of science is to follow a process of making careful and unbiased observations in order to generate knowledge about the world through tested theories based on the scientific observations. Although theories may not guarantee the absolute truth about a particular scientific theory, the idea is to get as close to an accurate approximation of the truth. The result will lead to a more accurate and credible understanding of how the natural world works.
Scientists seek to learn as much as possible about the nature of the world. By using intellect, the aid of scientific study devices, and formulated scientific hypothesis, scientists now have a better understanding of nature. For instance, the principles of motion and the law of gravity are applicable when studying other parts of the universe, even if we have yet to travel to these areas. The same principles can be applied to other forces such as seeking to understand ocean tides, bird migrations, earthquakes, and hurricanes. Scientists study patterns both in the natural world and in laboratories using technologically advanced research devices to gather data, take measurements, and make their observations and create their scientific theories. The result is an improved understanding of nature.
Science also helps us understand how we evolved. By studying such elements as fossils of species that once roamed the earth millions of years ago, various rocks and other matter located deep within the earth, skeletal remains of dinosaurs, and the remains of prehistoric man and early primates, scientists have made many significant discoveries about how we evolved. In fact, such famous scientists as Stephen Hawking, Carl Sagan, Albert Einstein, and Charles Darwin, have all contributed important theories and data that have brought us even closer to understanding how the universe emerged and developed.
How science has reconstructed the events in the history of the planet and its life forms have led to remarkable improvements and insight into how nature works. For instance, by studying the contours of the ocean floors, the shape of continents, the effects of a volcano eruption and earthquake, and where different fossils have been found, we get a better understanding of why our continents reside where they are and how human populations and species migrated and evolved to what we see today. We also get a better understanding of the results of the ice age and the effect it had on the types of species we have today. Understanding how the world evolved and the changes that took place also helps us to better understand current world problems such as the effects of Global Warming which is essential to finding ways to slow it down. By understanding how nature and its natural forces work, we are better able to come up with ways to manage the planet and its inhabitants.
Because science relies heavily on accurate and unbiased data, there is a constant development of advanced techniques and instruments which has lead to many astounding discoveries in the world and universe. For instance, the Hubble Telescope has resulted in many astounding discoveries about the stars, planets, black holes, and even far away galaxies. With advanced computer systems and other technologically advanced instrument, the future for scientific discovery looks bright concerning our understanding of the history of the universe and the history of life on earth.
