to the popular belief, science does not always exhibit the elements of a
definite, rigid field. Most scientists prefer to describe it as an ongoing work
in progress. This stems from the advancement over time that previously popular
theories tend to become obsolete with new observations. Such revelations
present twists which usher new research contrary to commonly held beliefs.
There are quite a few examples of new developments around us that have
triggered adjustments in conventional and popular scientific theories.
is a process of accumulating knowledge about the universe and building upon new
observations that illuminate the world around us. Theories are inherently
tentative, but as we use the scientific thought process over and over we become
increasingly convinced in them. Initially in the 17th century, the
continental drift theory was invented as an explanation for the shifting of
continents over time. However, developments in the 19th century
proved this theory to be wrong because the observations from laying of the
Atlantic telegraph cable and invention of sonar devices both proved that the
ocean floor was rugged comprising of underwater mountains and ridges (Williams
et al., 2010). As a result, it became apparent that the Earth was not always in
its current position but had shifted over millions of years.
through this insistent process, ideas are modified, expanded, and combined into
more powerful justifications. For example, quite a few observations about the
black hole have always been a subject of hotly contested debates.
Antecedently, scientists had observed that travel through space was constant
and that black holes trapped light which prevented it from escaping (Williams
et al., 2010). But with Einstein’s new observations from the Theory of
Relativity led to the discovery that light curves in space which breaks the
speed of light to overcome the gravitational pull from black holes. Since then
these perceptions have enabled contemporary scientists to develop better and
efficient formulas for terrestrial and space travel.
accepted all over are the best available explanations of how the world
functions. They have been thoroughly tested, supported by evidence, and have
proved to be useful in generating explanations and opening up new areas for
research. However, science is always a work in progress, and even theories
change in light of new observations. In the 17th century, pioneers
in biology thought that proteins defined the nucleus of a cell. However,
observations from studies in pus revealed that other substances were also in
play. This further led to the discovery of DNA, which is responsible for
carrying forward traits in subsequent generations (Williams et al., 2010).
theories are not always static but subjected to change. Results from
breakthrough observations often presents us with new dimensions and
perspectives from which existing theories are viewed. I believe, scientists
should always be on a constant lookout for identifying new aspects of existing
theories. It absolutely does not help science to take popular theories as
etched in stone whereas it is the duty of scientists to interrogate these
theories by making new observations to enhance the same.
