"Not Real but Relative" refers to something that may not physically exist, but has significance or meaning in relation to something else.
One example could be time. Time itself is not a tangible object, but our perception and measurement of it is important in relation to events and schedules.
"Not Real but Relative" has a basis in reality or existence, whereas something completely imaginary does not have any connection to reality.
In science, many things that are studied or observed may not have a physical form, but their effects or relationships with other objects or concepts can still be measured and understood. "Not Real but Relative" helps scientists to think beyond tangible objects and consider the intangible factors that may influence a system or phenomenon.
In everyday life, we often encounter things that may not physically exist but still have meaning and significance. For example, values and beliefs are not tangible objects, but they shape our actions and relationships with others. Understanding the concept of "Not Real but Relative" can help us to think more critically and broadly about the world around us.
