The widely accepted convention dictates that time follows a linear path. It originates from an indefinite point, theoretically positioned at infinity, and extends to another hypothetical point at infinity, but in the opposite direction. Within this linear continuum, every known and unknown event finds its place, each point corresponding to a specific date, hour, and even down to the tiniest fraction of a second. One of these points is dedicated to our birth, another slightly further down to our death, and between them unfolds our life - with all its events, joys, and sorrows. This narrative of existence intermingles with other life points on the timeline, each representing different experiences, other events, and so forth. For instance, a point before our birth might denote the commencement of World War I, while another, further back, could signify the arrival of the first European in the Americas. Following our death, the line hypothetically continues, possibly stretching towards a point where humanity ventures beyond the bounds of the solar system or marks the commencement of an entirely new era. This linear concept is typically regarded as a single, one-dimensional representation of time, encompassing all events in a solitary, forward-moving progression. Such is the conventional belief we draw upon to make decisions, construct hypotheses, and interpret the world around us.

However, could it be that this belief is subject to error? Not that we are unequivocally mistaken, but perhaps there is room for doubt. We place our trust in sensory perceptions and personal experiences to validate this perspective. Yet, it remains a formidable challenge to perceive anything that counters this deeply rooted convention. Our sensory perceptions are confined to the sensory organs at our disposal, but there is no assurance that these are the only senses required for comprehending and collecting information from our surroundings. In the natural world, we find numerous instances where animals possess keener senses than ours, perceive reality differently, or even harbor senses entirely foreign to us. Given this, it is not beyond the realm of possibility that, had biology endowed us with different or more acute senses in certain domains, our perception of the world might diverge significantly from the conventional view.

Let us then entertain a hypothesis - that the line is not straight and time is not one-dimensional or unidirectional. Picture a two-dimensional plane, denoted by axes X and Y, where a multitude of segments exists. Some of these segments are longer, others shorter. Some run parallel to each other, while others possess distinct inclinations or curvatures, causing them to intersect at various junctures - perhaps only once, possibly not at all, or maybe even two, three, or countless times. In certain regions of this plane, no segments traverse; they represent voids or points of separation. Each segment has a defined origin and terminus, and individually, none extends infinitely. However, it is entirely conceivable to move both forward and backward along these segments. Think of this as analogous to watching a movie. You can pause it and rewind it as often as you desire, navigating the timeline as you wish. The cursor, representing your point of focus, is bound to follow the path of the segment; it cannot skip scenes, for it must traverse the segment faithfully. Although it cannot leap ahead to bypass a scene, it repeatedly moves along the segment from the beginning to the closing credits and back again, countless times. When you rewind a movie, the characters within remain unaware, and each event can replay as if transpiring for the first time. Similarly, an entity moving backward along its segment would possess no memory of the future, as human memory functions unidirectionally - accumulating experiences only in one temporal direction and not the other.

Nonetheless, this unidirectional trait may be a biological limitation - a constraint within our capacity to perceive. Consequently, it is within the realm of conjecture that a life could unfold within a segment, oscillating ceaselessly between its endpoints. An individual might be born, live, die, then revert to live in reverse, potentially experiencing a life where aging reverses into rejuvenation, and where the accumulation of experiences transforms into their gradual erasure. With every passing minute, the slate of memory is wiped clean, and the cycle perpetuates, endlessly. Throughout each iteration, the entity would remain oblivious to this temporal fluctuation, as it is the workings of the human brain and memory that adhere to a unidirectional design, and it is this unidirectionality that constitutes the limitation, not the essence of time itself.
