An anology for research and knowledge

Knowledge is like a net, with lots of holes in it, big and small. When knowledge in a field becomes saturated, it becomes like a paper instead of being a net, however it is an utopia. Absolute knowledge does not exist.

Research is about finding and plugging holes in the net, there being innumerable holes in the ever expanding net. This is what we call identifying the research gaps. Hence research could be seen as filling the holes or gaps.

However , it does not stop there. The net is ever expanding. New knowledge is like extending the edges of the net
