<b>KNOWN AND UNKNOWN DIMENSIONS OF HISTORY</b>

<p dir="ltr"><i>The past, often referred to as history, holds the key to understanding human civilization and progress. However, not all past events are equally known or documented. This journal explores the two fundamental types of past: the Known Past, rooted in documented reality, and the Unknown Past, often speculative or based on predictions without concrete evidence. The study of history similarly divides into Known History and Unknown History, each with its respective foundation in truth or uncertainty. This paper further presents formulas that can assist in differentiating and analyzing these two types of history.</i></p>
