In the same way Hashem is infinite, His deeds are infinite.
In the same way Hashem is infinite, His deeds are infinite. That is why the wisdom in the Torah He gave us in infinite, and that is also why the wisdom in the universe He created is infinite. The more we learn, the more we see we don't know -- in both Torah and in science (see this video of the inner workings of a single cell), since both were written by the same infinite G-d.
When we say “Hashem Echad”, we’re supposed to think of the six ketzavot - all 4 directions, as well as up and down.
What is the secret in this yichud?
Hashem is absolute ONENESS, which means there really should only be one dimension. Like the Yud, which is only a dot without any hispashtus. And also there should be no time, because time allows for change and absolute oneness means no change ever.
So in order to create the universe, Hashem had to be metzamtzem Himself, kaviyachol. First He created the Alef Beis, which are hispashtus from the dot of the Yud. And through the letters He created space and time.
In addition, to create the complexity of the human being, there needed to be approximately 40-50 orders of size (10 to the power of 20 up, and -20 down- see this video). Size is relative, so to Hashem there is no such thing as big or small, only relative to the other things He created. So when He created the universe, he created approx 40-50 orders of size as well (perhaps more, we don't know). The bigger things need to be relative to other things, the more diverse the universe must be. Again, this is only possible through a tzimtzum of His absolute oneness.
So perhaps the 6 ketzavos of our universe are:
The 3 dimensions of height, width and depth
Time
Size in both directions relative to the human being, both bigger and smaller than us.
Every one of these things is therefore seemingly a stirah to Hashem’s absolute oneness, and that’s why when we say ECHAD in Shema, we think of all directions and dimensions. We are mechaven that all of space and time doesn’t really exist outside of Hashem Himself, and is only possible through His being metzamtzem Himself.
Part 2
After thinking more about, I realized some interesting things. First of all, the initial “something” that the Big-Bang sprang out of is known by scientists as a “Singularity” (see here). This is the absolute Oneness of Hashem, because Hashem has no spatial dimensions, He contains everything in a place with no space. He is called Makom, because He is “Mekomo shel Olam”. He doesn’t exist inside the universe, but rather the universe exists in of Him. So this singularity - was a “ONENESS THAT CONTAINED ALL”, and it is/was Hashem somehow.
Now in order to create the world, there needed to be diversity. There needed to be numbers greater than one and dimensions which are able to facilitate multiplicity. Also, “Time” is needed to allow for change, because without Time, how could the singularity expand? If there’s no time, there’s no change. So time had to be created together with the expansion.
Bereishis - In the beginning - Time.
Bara Elokim - G-d created
Es Hashamayim - the 3 dimensions of space
ve’es ha’aretz - and matter.
In the very first millionth of a trillionth of a millisecond of the initial expansion of the Big Bang, there had to be an initial contraction of G-d’s Oneness so to speak, to allow for “more than one”.
Now in order to create man, the universe actually needed many, many levels of multiplicity. If the universe wasn't the size it is today, the great variety of atomic types, especially Carbon, wouldn’t have developed. The types of atoms necessary for life were created only through billions of years, and through the birth and death of stars which created new types of matter, which eventually found their way to Earth and became the building blocks for life.
Life requires an astronomical level of complexity (meaning, combinations of individual particles) both from the atomic level and upwards until Man, and also from Man, upwards, until the size of the universe itself. (I wonder how many multiples of the initial singularity Hashem had to expand the universe to reach this level of complexity. Was it 10 to the millionth power? Or perhaps a million pickles?).
Perhaps this the meaning of the name Sha-dai, as Chaza”l explain,that He said to His world dai - “Enough” - i.e. “Stop expanding”. Hashem saw in His great wisdom exactly how many orders of size were necessary for the complexity of life, and this expansion required Him to be metzamtzem (contract) Himself - His Oneness - so to speak - in order to allow for multiplicity. And I believe that Hashem wouldn’t contract Himself more than necessary, and therefore, as soon as the size needed for the complexity of life was reached, He said “dai”.
Part 3.
After writing to you and Ma about this idea on Wed and Thurs night... (short recap: the postulation that there's a type of mathematical numerical 1 called "Absolute One", which existed in the instant before the Big Bang, that both can’t be divided and that equals infinity. And I believe that this phenomenon still exists outside the dimensions of our universe. And in order to create the universe, Hashem had to contract Himself, so to speak, to allow for mathematics to even exist. And He did this by expanding the space within Himself, so to speak, to allow for "more than 1").
Anyway, on Shabbos, I just “happened” to open up the first volume of the תלמוד עשר ספירות that was lying on the table in the shtiblach, and I read the following from the Ariza”l (here's a very rough translation of the idea from memory):
Before everything, there was only a single nekudah which was an absolute oneness, that no creature or angel can even comprehend. And when Hashem decided to create the world, he was metzamtzem (contracted) himself equally in all directions, in order to allow for the creation to exist, and creation expanded in all directions like a circle… . And the 10 sefiros led from one to the next, inwards, from the outer circle, without touching the outer circle (which is the "ein sof" - infinity itself, because if it would touch it, it would become included within it and not be part of creation) inner circles, upon inner circles, until this world, which is the farthest from the ein sof, and therefore the most megusham (physical) … And each of the sefiros has within it 10 sefiros, and so on, like layers of an onion… ad infinitum…
Doesn’t that sound like concept of Absolute One, that we can't comprehend? And doesn't this sound like the seemingly infinite orders of size (that I was talking about before) that the universe is comprised of, multiples of 10, in order to allow for the complexity of life? It’s incredible that these words, which I don't remember ever seeing before, seem to reflect the exact ideas I was writing about above! It’s like Hashem was reassuring me that although my parents both dismissed my ideas as wacko, there is some truth to what I wrote... (I don't claim to understand it, just as "concepts")...
I believe that the Universe, Torah and Kabbala are all one, having all been designed by the same Creator. And although Ima will probably be upset by what I wrote here and tell me to stay away from trying to interpret the Ariza"l with no prior training (and she'd be right) I still believe that the physical universe and the spiritual worlds are parallel, and in the same way that Hashem had to contract Himself, so to speak to create the spiritual worlds, He had to contract Himself to create the physical world. Spiritual and physical are just different manifestations (or levels, or reflections, or like ancestors, if you will) of the same phenomenon.
