Conventional concepts of communication deal with information encoded in signals, signs and symbols (r). For such messages, energy travels along the known sensory pathways and varies with conventional time (r), a "one-dimensional-like" time always moving from past to future at a rate tied intrinsically to the average rotation of the planet Earth. 

     Consider a different form of communication where energy also travels along the known sensory pathways but where information is encoded in "perceptions of lateness" measured in a rhythmical, "two-dimensional-like," rotating time called RBT or "Rhythm Based Time." Let a) the "two dimensions" of  RBT be at right angles (orthogonal) to the "one dimension" of conventional time and b) the "RBT Plane" containing this new type of time proceed in a forward direction along the "arrow" of conventional time at the above mentioned conventional rate. 

     Synchronization is defined as occurring at the same time. Two synchronized turning wheels have locations on one wheel that repeatedly occur at the same relative positions of turning, and at the same times as similar locations on the other wheel. We can characterize this concept by saying that each wheel's phase (position of advancement within a cycle) remains identical. The wheels are said to be "phase-locked" during synchronization (r). 

     Let biological rhythms be represented by rotations in the RBT Plane where each rhythm is characterized by angular velocity and phase angle (rotational measurement of phase). Define "On Timeness" as an arbitrary zero phase angle of a biological rhythm. The rotations that represent biological rhythms are similar to the aforementioned wheels, where the wheels are imagined as turning about axes of conventional time (Diagram 1, postscript #19). In order to have this new type of communication initially, biological rhythms must be shared between two organisms so that synchronization (phase-lock) occurs between the two rhythms, one within each organism. Then and only then can information encoded in RBT pass between the organisms. RBT can now be precisely defined as: The Perception of Lateness Relative to On Timeness. Such information flow is "Rhythm Based Communication" (RBC). 

     Imagine two parallel "arrows" of conventional time, each associated with one of two communicating organisms, A and B, as shown in Diagram 1, postscript #19. (The term "arrow," in reality, refers to a vector, having both magnitude and direction, such as moving energy or mass, whereas time, like temperature is a scalar, having magnitude only). Now picture two turning wheels with their centres on the "arrows" of time, with different angular velocities, referred to as "alpha rhythms." The duration of one rotation is referred to as an "alpha concept." 

     To arrive at synchronization, organism A makes a signal in any time window (or time slot) of wheel A, but only when the window reaches the vertical or "NOW-axis" (Diagram 1, postscript #19). The signal (S) simultaneously occurs on the "arrow" at the conventional time given by the position of the centre of the wheel. Organism A then repeats this action on the next one or more complete cycles of its wheel. The proposed alpha concept can be confirmed by organism B, if its signal also occurs in a synchronous time window centred on the NOW-axis of any of its subsequent rotations, which action then defines the concept of On Timeness (or zero lateness). Information is now transmitted between A and B (as per Diagram 1, postscript #19), in various perceptions of lateness, in binary, 1,1,0 (late, late, on time), in tertiary, 1,2,0, (late, later, on time) and so forth. 

     (After sections on major differences in RBT, how RBC differs from conventional communication, observations it explains, where earlier ideas have failed, our observational and experimental design with whales, dolphins, red fox and bald eagles, results and interpretations, the following concluding hypothesis is presented.) 
       Note: The reason why RBT is described as "two-dimensional" (which description is purposefully placed in quotation marks), when physical concepts of time clearly have NO "spacial dimensions," will  be somewhat clarified in postscript #105 but with a more detailed description now in postscript #121.

     Living organisms encode information in Signals, Signs and Symbols (which encoding is hereby called SBC or "Signal Based Communication") as well as in RBT (which encoding is hereby called RBC). The former is more well known for humans as well as various forms of Nature that are undergoing higher states of biological stress, the latter mainly occurs during low biological stress. These dissimilar, separate modes of communication are received, analyzed, remembered and acted upon by separate biological mechanisms, components of two separate minds. There seems no reason why parts of the two minds cannot take up the same physical space within the organism. RBC could have unconscious reception in virtually any cell of a living organism and such information may indeed produce feelings which may be transferred to a presumed smaller number of cells in a conscious mind. The conscious specializes in Signal Based reception, analysis, memory and actions; it also receives feelings from both Signal and Rhythm Based information. Regarding these latter activities, the organism may be fully aware. 

     RBT is a rhythmical, "two-dimensional-like," rotating time which is at right angles (orthogonal) to conventional time and proceeds in a "forward direction" along the "arrow" of conventional time. The RBT Plane has a "characteristic corridor" centered on a NOW-axis (Diagram 1, postscript #19), with an arbitrary phase angle, which corridor remains always in the present and from which information in the form of signals, signs and symbols is instantaneously transposed to and from conventional time. However, only information arriving in any of a number of preassigned (and often confidential) rotating RBT windows has RBC meaning, and only then when the RBT windows coincide with the fixed characteristic corridor. 

     RBC could work for all animals (and in fact for all life). Should this be the case, then a universal greeting is feasible. A group of living organisms should be able to send and receive messages, using RBT, as if they were physically together, independent of spatial separation. Also larger vocabularies could be expected and body language should play an extensive role in communication. It should become not only important WHAT the organism does, but perhaps even more important WHEN the organism does something. 

     The belief by most that time passes is only for "one dimension" of time. For the other "two dimensions," which lie in the RBT plane, and into which many claim to have transcended, time does not pass. Here time remains in the present (r). My feeling is that some humans, and most of Nature know this. So we must expand our consciousness to all "3-dimensions" of time and freely move between them. We must amplify this expansion by the scientific development of RBC throughout the biosphere, in order to improve our benefits from Nature, and to acquire higher degrees of harmony with Nature.
