Eternity Between the Cherubs

Eternity Between the Cherubs

By Alexander Poltorak And there I will meet with you, and I will speak with you from above the cover, from between the two cherubim which are on the ark of the testimony, of all that I will command you concerning the children of Israel. (Exodus 25:22) Introduction The Torah section Terumah contains instructions given to Moses by G‑d about several important elements of the Mishkan (the Tabernacle), such as the Ark of the Testimony (Aron), the cherubs (cherubim), menorah, and the altar. After concluding the instructions concerning the making of the Cherubim, G‑d tells Moses that it is from between the Cherubim that He will speak to Moses. Midrash Tanchuma explains: The Holy One, blessed be He, said to Moses: “From between these two figures—these cherubim—shall I converse with you; there will [...]

Rosh HaShanah: The Beginning of Change II

Abstract This essay explores the profound connections between language, philosophy, physics, and spirituality in the context of Rosh HaShanah. By examining the linguistic roots of “shanah” (year), “shinui” (change), and “shnei” (two), the essay uncovers a rich tapestry of meaning that addresses the fundamental question: Why is there change rather than permanence? The study traces the metaphysical concept of change from ancient Greek philosophy through medieval Jewish thought to modern physics, highlighting the paradoxical relationship between the Infinite Creator and finite creation as expressed in Kabbalistic and Chassidic concepts of mati ve’lo mati and ratzo va’shov. The essay concludes by proposing a relational view of time and change, aligning Jewish mystical thought with contemporary physics, and presenting Rosh HaShanah as an opportunity for renewing and deepening our relationship with the Divine. Introduction In [...]

Rosh HaShanah—the Beginning of Change I

It’s All in the Name Rosh HaShanah is usually translated as the New Year. When translated literally, it means the “Head of the Year.” In this essay, I suggest an alternative (almost literal) translation that reveals a new meaning. The word "rosh" is cognate with "reishit," meaning “beginning.” The word "shanah" is cognate with "shinui," meaning “change.” Therefore, Rosh HaShanah can be translated as the Beginning of the Change. Aristotle equated time with change (Physics). Change itself is unthinkable outside of time as change can only occur in time—first, there was something, and then, it became something else. So, change and time are essentially synonymous. Thus, we can translate Rosh Hashanah as the Beginning of Time. Moreover, what is the beginning? Any process extended in time has the beginning, the middle, and the end. However, what is the [...]

The Mystery of the Eighth Day

The Mystery of the Eighth Day

And on the eighth day, the flesh of his foreskin shall be circumcised. Leviticus 12:3 In the Torah portion of Tazria, we are commanded to circumcise a male child on the eighth day. In the previous Torah portion, Shemini, we read that the dedication of the Tabernacle (Mishkan) also took eight days, and only on the eighth day the Shechinah (“divine presence”) rested on it. What is the significance of the eighth day? Chasidic philosophy interprets the eighth day as the day after seven days. In numerous writings (ma’amarim) and talks (siḥot), the Rebbes of Chabad stated that seven days represent nature, whereas the eighth day is a day above nature.[1] The eighth day represents the supernatural. Why, you may ask, do the seven days represent nature? We are told that the number [...]

Time and Space as Emergent Phenomena — Abstract

The current Torah portion Beshalach tells about the splitting of the Sea of Reeds. As I discussed in my essay, “Collapse and Revelation,” the splitting of the sea is a metaphor for the collapse of the wave function in quantum mechanics. The Alter Rebbe, the Baal HaTanya, taught us to leiben min hatzait (“to live with the time,” that is, to leave with the current reading of the Torah). Maybe this is why, this week, when we read in the Torah portion Beshalach about the splitting of the sea, I finally understood where time comes from. This question haunted me for more than forty years. Finally, this week, I got it—time emerges through the interaction of consciousness with the universal wave function, causing the sequence of wave function collapses that we perceive as [...]

Principle of Least Action III — History

Principle of Least Action III — History

The spectacle of the universe becomes so much the grander, so much more beautiful, the worthier of its Author, when one knows that a small number of laws, most wisely established, suffice for all movements. Pierre Louis Maupertuis (1744) Among the more or less general laws, the discovery of which characterize the development of physical science during the last century, the principle of Least Action is at present certainly one which, by its form and comprehensiveness, may be said to have approached most closely to the ideal aim of theoretical inquiry. Its significance, properly understood, extends, not only to mechanical processes, but also to thermal and electrodynamic problems. In all the branches of science to which it applies, it gives, not only an explanation of certain characteristics of phenomena at present encountered, but [...]

Time as a Combination of the Past and the Future

Philosophers struggled with the notion of time from the dawn of human civilization. Physicists of today declared the problem of time the number one problem in theoretical physics. Jewish mysticism has much to say about time.[1] Rabbi Ḥayyim Vital, in the name of the Arizal, quotes a verse: בִּטְחוּ בַיהוָה עֲדֵי-עַד, כִּי בְּיָה יְהוָה צוּר עוֹלָמִים Isaiah 26:4 The standard English translation of this verse, by JPS is: Trust ye in the LORD for ever, for the LORD is GOD, an everlasting Rock. Isaiah 26:4 This is not a very good translation because it doesn't tell you what specific names of G-d are used in the pasuk. Let us spell out the names in this pasuk to see what is going on: Trust ye in Havyah (Y-H-W-H) for ever, for Kah (Y-H) is [...]

Metaphysics of Time in the Eyes of Philosophy and Kabbalah

A-Series and B-Series as Zman and Seder HaZmanim McTaggart’s series A and series B are two conceptual frameworks proposed by the philosopher J.M.E. McTaggart[1] to analyze the nature of time and its relationship to temporal properties such as past, present, and future. J. M. E. McTaggart, by Walter Stoneman, 1917 In McTaggart’s series A, also known as the “A-series” or the “temporal series,” time is understood in terms of the temporal properties of past, present, and future. The A-series categorizes events based on their temporal relations, such as past, present, and future, which are considered essential aspects of events. The A-series views time as a succession of moments where events move from the future, through the present, and into the past. It emphasizes the dynamic and changing nature of time, with events shifting their [...]

Sanctuaries in Space and Time

Sanctuaries in Space and Time

We are quite familiar with space—we move freely in space back and forth; we concur space on land and beyond; we reclaim land from sea; we turn deserts into gardens; we turn desolated space into sprawling cities. We are, on the other hand, helpless in the face of time. We cannot move freely in time. We can’t move back in time. We are swept forward in the inexorable flow of time. We do not understand time; we cannot change it. We are masters of land, but not of time. It is for this reason, when G‑d instructed Moses how to build a sanctuary for Himself, He could not have started with time—we would have not the faintest idea what it meant—a sanctuary of G‑d in time—let alone how to do it. That is why G‑d started with space, instructing Moses how to build the Mishkan—a Sanctuary in space—first. Only then He commanded Moses about Shabbat.

Noah’s Ark—Three Layers of Reality

Noah’s Ark—Three Layers of Reality

A light shalt thou make to the ark…with lower, second, and third stories shalt thou make it. (Genesis 6:16) We mentioned in the previous posts that Noah’s ark was a microcosm.[1] As we discussed in the previous post, “Noah’s Ark—Three Layers of Being Human,” most structural parallels related to Noah’s ark are based on its tripartite structure —that is, its having three tiers. In Chasidic thought, the three levels of Noah’s ark correspond to three worlds of BiYA—Beriyah (the World of Creation), Yetzirah (the World of Formation), and Asiyah (the World of Action). In this essay, we will investigate how the tripartite structure of Noah’s ark is reflected in the structure of reality. We might say that the totality of existence comprises three layers—physical, informational, and spiritual. The classification of reality into three [...]

Let There Be Light

Let There Be Light

And G‑d said: “Let there be light.” And there was light. And G‑d saw the light, that it was good; and G‑d separated between the light and between the darkness. And G‑d called the light day, and the darkness He called night. And there was evening and there was morning, one day. (Genesis 1:3-5) This short passage from Genesis presents several difficulties that many classical commentators struggle to address. The first problem has to do with darkness and the separation of light from darkness. As we know today, darkness is not a substance—it is merely the absence of light. The verse states that G‑d separated between the light and the darkness. Presumably, before this “separation,” the light and the darkness existed together. How is this possible? By definition, the presence of light [...]

Nadab and Abihu — Tragedy in Time

Nadab and Abihu — Tragedy in Time

And Nadab and Abihu, the sons of Aaron, took each of them his censer, and put fire therein, and laid incense thereon, and offered strange fire before the Eternal, which He had not commanded them. And there came forth fire from before the Eternal and devoured them, and they died before the Eternal. (Exodus 10:1-2) And Aaron spoke unto Moses: ‘Behold, this day have they offered their sin-offering and their burnt-offering before the Eternal, and there have befallen me such things as these; and if I had eaten the sin-offering to-day, would it have been well-pleasing in the sight of the Eternal? And when Moses heard that, it was well-pleasing in his sight. (Leviticus 10:19) The Torah Portion Shemini tells two stories: One of the tragic death of two sons of Aaron—Nadab (Nadav) and Abihu [...]

In the Beginning — It’s All About Change

In the Beginning — It’s All About Change

In the beginning G‑d created the heaven and the earth. (Genesis 1:1) The first verse in the Torah is key to understanding the fundamentals of creation. As far as physics is concerned, there are three key words in this verse, which are highlighted in bold: In the beginning G‑d created the heaven and the earth. According to Nachmanides, these three words—“beginning,” “heaven,” and “earth”—represent, respectively, time, space, and matter. It is easy to see that the “beginning” stands for time, because the “beginning” is clearly a temporal concept that sets off the beginning of time; that “heaven” is a metaphor for space, because the stars and the planets are perceived to be in the sky (i.e., heaven) when, in fact, they are moving in space;[1] and that “earth” is emblematic of matter, [...]

It Is Not Good For Man To Be Alone

It Is Not Good For Man To Be Alone

And the Eternal G‑d said: “It is not good that the man should be alone; I will make him a helpmate opposite him.” (Genesis 2:18) The end of this verse is rather puzzling. Why would the woman designated as a helpmate for Adam be opposite (literally “against”) him? One can perhaps soften things by translating the Hebrew eizer kenegdo as “counterpart.” However, in a literal translation, the question remains. A simple explanation is well known: if a man is worthy, his wife would be his best friend, ally, partner, companion, and helpmate. If the man is not worthy, however, his wife would be his opponent and antagonist. An esoteric interpretation offered by Rabbi Shneur Zalman of Liadi, in his commentary on this verse in “Torah Ohr,”[1] provides a deeper meaning. He writes [...]

Three Angels: Past, Present, and Future

Three Angels: Past, Present, and Future

And the Lord appeared unto him in the plains of Mamre, as he sat in the entrance of the tent in the heat of the day; and he lifted up his eyes and looked, and, behold, three men stood over against him… (Genesis 18:1-2) In the Torah portion Vayeira, three men appeared to Abraham as he was sitting at the entrance to his tent. The Talmud states that these three men were angels: Michael, Gabriel, and Rafael. Michael came to tell that Sarah will give birth to a son; Raphael came to heal Abraham after his circumcision; and Gabriel came to destroy Sodom. However, on a metaphorical level, it appears to me that these three angels personify three aspects of time: past, present, and future. Here are several clues that hint at [...]

Noah’s Ark — Sailing through the Flood of Time

Noah’s Ark — Sailing through the Flood of Time

Time is a storm in which we are all lost. " (William Carlos Williams, Introduction to "Selected Essays") I always had a hard time relating to the story of the Flood on a literal level. Why would G‑d want to wipe out all people He created in full knowledge that they would sin? Like it was a surprise for G‑d! G‑d, who exists above time, which He created, cannot be surprised—He knows the future. Then why to create humanity, just to destroy it later? And animals. . . what was their fault? They have no freedom of choice. They act on instincts hardwired in their genome as they were created. Why punish them? Lots of questions, few answers. If the Torah says the flood happened, it must have happened. However, the Torah is [...]

Cosmic Symphony

Cosmic Symphony

Strings vibrate, Souls tremble, Angels are running and returning, G‑d is touching and not touching – The rhythms of the universe… Nothing stays still… all is in flux. The inexorable flow of time is synonymous with the existence itself. Indeed, everything exists in time. However, from where does the time come? This is, perhaps, the greatest mystery of science. In modern physics, we do not know what time is, let alone from where it comes. We only know how to measure it – by counting the number of periodic intervals, which we accept as a unit of time. For example, in antiquity, people used a night-day cycle as the basic unit of time. This cycle was born out of observations of the apparent rotation of the sun around the earth (although, in reality, [...]

Fitting Pieces of the Puzzle Together

Meditations on the Maaseh Merkavah – IV This is the fourth and the final installment in the series of posts related to Ezekiel’s prophesy, Ma’aseh Merkava, “The Making of the Chariot.” For background information, refer to the previous posts, “Space – Between Future and Past,” “Relational Space,” and “Collapse of the Wave Function.” Regular readers of my blog may be wondering about my last post “Futurist Interpretation of Quantum Mechanics,” which was about my new interpretation of quantum mechanics. This is not a physics blog, however; the Quantum Torah blog is about Torah and physics (or, more broadly, Torah and science). What did the last post have to do with Torah? Hopefully, it will all now become clear. Last Shavuot I had a very unusual experience. Sitting in shul listening to the reading [...]

Futurist Interpretation of Quantum Mechanics

(A popular summary of the paper “Towards Futuristic Interpretation of Quantum Mechanics” by Alexander Poltorak being currently prepared for publication) Quantum mechanics (QM) is one of the most successful theories of physics that withstood the test of time. Indeed, it is one of the best-tested theories known to science. Yet, we hardly advanced in our understanding of the meaning of QM since its inception almost a century ago. The indeterministic nature of the theory puts it at odds with both classical physics and our intuition, and continues to perplex physicists and philosophers of science today as it perplexed Einstein, who famously said, “G‑d does not play dice with the universe!” Superposition and entanglement seem to defy common sense and, yet, they have been confirmed experimentally time and again. The phenomenon known as the [...]
