truth-value gaps

A truth-value gap occurs when a statement cannot be clearly identified as either true or false. This can happen in cases where there's insufficient information, when the statement refers to future events, or involves concepts that don't have a definite answer. For example, "Tomorrow, it will rain" has a gap until tomorrow arrives and we observe the weather. Essentially, a truth-value gap highlights situations where our usual way of assigning truth or falsehood doesn't apply, leaving the statement temporarily neither true nor false.
