"Unquestionable" refers to something that is beyond doubt or cannot be disputed. It signifies a level of certainty or truth that is accepted without hesitation. This term is often used in various contexts, such as science, philosophy, and everyday life, to describe facts or beliefs that are widely recognized as valid. In legal terms, "unquestionable" can refer to evidence or testimony that is so strong that it leaves no room for doubt. For example, in a court case, DNA evidence may be considered unquestionable, as it provides definitive proof of a person's identity or involvement in a crime.
