Fact and Theory

    According to Pratt (1998) facts usually remain the same and theories often change.Facts are also empirically true and can be support by evidence.This tells us that fact,are remain the same even for decades.While theory are changing according to current situation.Theory are make out by making research where it will lead the research of what is happening.Theory are make out based on 3 steps of methodology ,Pratt (1998) which is first,make an observation,second come out with a theory and lastly use the theory to predict future observations.It is necessary to repeat those steps until the research question are answered.

   Pratt (1998) stated that, general in science, "facts" refer to the observations.This will tells us that fact do related to theory.Fact is also something that has happened such as space travelling is commonly true.Hence,we can conclude that theory is based on our personal observation after making assumption from other,meanwhile,fact cannot be change and will remain same because it is something that people hold on onto many years.
