We can take another example for this. What we see there is a wall. Why do we call it a wall? We call it a wall because it is an obstacle and we cannot see or go through it. Since it is an obstacle, we call it a wall. But when we look at if from the scientist’s point of view, there is an enormous amount of vacant space between the atoms that constitute the wall. Although we call it a wall looking at it with our bare eyes, when a scientist looks at it, he says that there is a lot of space just as there is a lot of space between several stars that we see in the sky. Thus, we undertake to get a clear picture of many things with the help of sciences.
