I prefer not to trouble myself, and my primitive mind, with the precise nature of the 4 known and perceivable physical dimensions. The contemplation and intellectual contortions required to untangle the nature of our physical dimensions is much too massive a cognitive undertaking and at times it seems wise to leave that to the trained physicists, even though they are just as puzzled as I am, albeit behind the cloak of fanciful guesswork that is draped in esoteric notions and descriptions that I am unable to conjure because I lack the vocabulary and training.
In fact, a couple of physicists from opposite ends of the country have teamed up in a quest to deconstruct physical dimensions. Tackling the novel approach, Jonas Mureika from Loyola Marymount University in Los Angeles, and Dejan Stojkovic from SUNY at Buffalo in New York, have postulated a theory that physical dimensions themselves underwent a massive “physical evolution” in the billions of years since the “Big Bang” event which precipitated our universe’s existence as we know it. According to their theory, Big Bang dimensions may have existed in a limited primordial physical state which included only 2 dimensions, one of space, and one of time. According to the scientists, this tenuous early stage of existence can best be described as a state approaching that of a…straight line! As the latent energy level of the universe began to decline, to “cool,” 2nd and 3rd spatial dimensions were added, thus leading to our present configuration of 3 spatial and 1 time dimension. Mureika and Stojkovic explain that as the universe’s energy level plummeted, it also concomitantly expanded, and such cosmically massive movement caused the single spatial dimension to enfold upon itself, thus creating extra dimensions that we now are familiar with.
This is amazing stuff. Consideration of physical dimensions boggles the mind. In fact, quantum physics postulates many additional dimensions unseen and unnoticed by our rudimentary senses.
And this is the truly astounding part. Not the dimensions themselves, but their effect on our resultant biological evolution. The 5 physical senses we have developed are attuned auspiciously to translate physical existence through the screen of the 4 major dimensions. The lower quantum dimensions are so “trivial” in the respect that they have had no effect on our biological evolution, or they have escaped notice, anyways. And I wonder if our physical senses were in fact shaped by the presence of the major physical dimensions that were created in the wake of the big bang. Or is it that our senses are merely generalized perceiving tools that have molded around the stimuli presented by the 4 dimensions we live in? What came first? The physical dimensions of our universe or the primary senses we use to describe and acclimate them to our limited reality?
And furthermore, we seem to shortchange the dimension of time because it is so incomprehensible to us. Have our senses been unable to keep up or adapt to the concept of time beyond the forward moving linear train that we perceive it as?
If space has 3 visible dimensions, why should time be limited to only one? Our eyes allow us to visualize 3 spatial dimensions, but which of our senses can ever allow us to “visualize” time? Time seems to be a figment of our instinctual logic that is compiled through input of concrete spatial measurements.
