What is the difference between the questions below?
● Science is currently addressing?
● Science cannot yet answer?
● Science will never be able to answer?
The main difference between the premises is the application and role under scientific inquiry under the axioms of possibility and plausibility.
Science is currently addressing- Is the platform from which scientific inquiry will expand. Its premise is that it is exploring possibilities and it is open to explore plausible scenarios and additional outcomes.
Science cannot yet answer- Is the first step out of scientific inquiry. After addressing what science is currently investigating, you ask "what HASN'T it found out about it. It is like a non-example, in which you compare and contrast the real and the plausible. It is a neccesary step to start an investigation, and opens the door more widely to both the possible and the plausible. It is not reductive, or limiting.
Science will never be able to answer- Is a reductionist view of scientific inquiry. "Never" is not a part of the scientific lexicon. It minimalizes every possibility and plausibility involved in the experimentation process, and it denies any diverse view of the same problem, which is a counteraction of scientific inquiry. There is no "never" in science.
In looking over the questions that you posted there are some significant differences in the questions.
The first "Science is currently addressing?" relates to the discoveries and testing that is currently in progress. There is a vast amount of research and field evaluations and experiments ongoing in medicines, space, genetics, alternative fuels, carbon footprints, environmental damage, etc..
The second question "Science can not answer yet?" relates to the experiments and information about life and our world and universe that has not been solved. The technology has not been developed that will lead others to the knowledge that one day mankind will have available. Science is progressing at a rapid pace as new instruments develop and the world searches for answers to self-created problems such as the depletion of fossil fuels. Science is not stagnant and it will always move forward in man's quest for knowledge.
The third statement "Science will never be able o answer?" is indicative of the things that mankind is just not going to be able to figure out. No matter how much knowledge man gains there will always be things that will exist that man will not ever be able to figure out. It is man's quest to solve the riddles of the world and universe that drives science. However, not all knowledge will be attained by man. In addition, as one new thing is discovered it leads to many other questions and things to learn. It has a domino effect in regards for man's need to know more.
