:י"ג Four Dimensions

כיון דאמליכתיה למעלה ולמטה ולארבע רוחות השמים תו לא צריכת
Here is a shtikle I wrote many years ago on פרשת בראשית which pertains to the ideas mentioned in our גמרא.

The advances in modern science over the years have allowed us to learn much about the history of the world.  Scientists have been able to establish a pretty clear picture of all that preceded us. However, the instant of creation is a point beyond which no discoveries may be made. Even the most prominent of scientists, such as Stephen Hawking of the University of Cambridge, have come to the realization that "the creation lies outside the scope of the presently known laws of physics." What existed before the creation of the world is beyond human understanding. The simple explanation for this is that before the world was created, whatever it was that existed lacked the basic components necessary for human conception.

All the matter in the universe exists in three dimensions - length, width and height. We do not live in the two-dimensional world of comics and cartoons, nor can our minds conceive of something physically consisting of more than three dimensions. When a cube of a given volume is removed, it leaves behind a space, filled with air, of identical volume. However, before the creation of the world, there was nothing. The second pasuk of the Torah asserts that before creation, the world was "tohu vavohu." Rashi explains "vohu" as emptiness and void. He writes that "tohu" denotes astonishment and wonderment, as one would have been astounded by the emptiness that existed. Indeed, we are astonished to the point of incomprehension at the very idea of nothingness. It is beyond the grasp of human thought and will never be understood. An integral component of creation was the establishment of the infrastructure necessary for the existence of the world as we know it. On the second day, the waters are divided into the upper and lower waters. This is the first evidence of a dimension in creation. However, there was only one. Left, right, forward and backward did not yet exist - only up and down. The next day the waters were collected to form the oceans and reveal land. The three dimensions were now in place.

 Although a physical object may be comprised of no more than three dimensions, there is another dimension commonly included as the fourth - time. Before the creation of the world, time did not exist either. In fact, the word "before" is probably a misnomer. Before implies that which preceded in time. If there is no time, there can be no precedence. This, too, is beyond the comprehension of the human mind. With the first day of creation, the concept of time was implicitly infused into the universe.

Perhaps, these ideas are directly pertinent to one of the central laws of Keriyas Shema. The essence of Shema is the acceptance of HaShem’s kingship upon us. One is required to include this concentration with the recitation of Shema or he does not properly fulfill the mitzvah (Shulchan Aruch OC 60:5). Ideally, this is accomplished with specific focus on the "ches" and "dalet" of "echad," as explained in 61:6. The ches corresponds to HaShem’s rule over the earth and the seven levels of Heaven. This is a one-dimensional focus in concurrence with the events of the second day of creation. The dalet corresponds to the four directions, essentially, the other two dimensions, over which HaShem rules. This coincides with the events of the third day. Hence, HaShem’s dominion over the three physical dimensions. The Mishnah Berurah (63:11), in the name of Levush and Magein Avraham, writes that "Baruch Sheim Kevod, etc." is subject to the same concentration requirements as the first pasuk. In this pasuk, as the words clearly indicate,  we assert the eternity of HaShem’s kingship. In essence, we are declaring HaShem’s rule over the fourth dimension, time.
