Fill the Earth

And G‑d created man in His own image, in the image of G‑d created He him; male and female created He them. And G‑d blessed them; and G‑d said unto them: “Be fruitful, and multiply, and replenish the earth, and subdue it . . . .Genesis 1:28 G‑d created man, male and female, and commanded them to be fruitful and multiply, fill the earth, and subdue or conquer it. While the literal meaning of this verse is apparent—fill the earth with your progeny by procreating[1]—it begs a question. Specifically, the phrase “fill the earth” seems superfluous—wasn’t it enough to say “Be fruitful and multiply”? Indeed, the Hebrew word milupim[2] (“to multiply”) is etymologically related to the word mil’u[3] (“to fill”).[4] If humans were to multiply, as commanded by G‑d, they would naturally fill the earth. It seems [...]

The Cosmological Problem of Initial Conditions and the Universe of Tohu

Now the earth was unformed and void.Genesis 1:2 We have a big problem in cosmology: the problem of the initial conditions of the universe at the time of the Big Bang.[1] Before we can explain this problem, however, we need to review some basic concepts of thermodynamics. Thermodynamics developed by Boltzmann and others[2] described the behavior of gases and liquids and the transfer of heat. A key concept in thermodynamics is entropy. Entropy is a measure of disorder, of chaos. The second law of thermodynamics states that in an isolated system, entropy always increases with time. The second law of thermodynamics explains universal decay. And entropy is the measure of that decay.[3] Shining stars produce entropy. Stars collapsing into black holes produce entropy. Evaporating black holes produce entropy.[4] Entropy is increasing in the universe.[5] Let us [...]

Let’s Make this Sukkot About Ananei HaKavod, not about Ananei ha-COVID

During the Holiday of Sukkot, we celebrate the divine providence that protected Jewish people from the sun and other dangers of the desert during their forty years of wandering in the desert. This providence came in the form of the ananei ha-koved (“the clouds of glory”). The clouds of divine glory hovered over Jewish people protecting them from the elements—hashgachah pratit (“divine providence”) was openly revealed. The concept of divine providence is often misunderstood. People expect open miracles. Nowadays, we no longer merit the open revelation of divine providence, which is concealed. However, it is still here guiding and protecting us, if we open ourselves to its protection. This reminds me of an old parable. After a shipwreck, a Jew was stranded on an uninhabited island. The Jew prayed to G‑d for a [...]

Yom Kippur—The Day of Pure Delight

Yom Kippur means “The Day of Atonement.” Some view it as a frightening day full of regrets of the past and anxiety for the future. However, Chasidic philosophy sees Yom Kippur as the day of pure delight. On a simple level, Yom Kippur is the day of forgiveness--the day when we all going to be forgiven, cleansed, and atoned. What is not to be happy about? Moreover, it is a day when we get our personal rendezvous with our Heavenly Father, and with ourselves. The last prayer of Yom Kippur is called Neila ("closing"). It is usually interpreted as the closing of the doors of prayers when the penitent feverishly trying to squeeze another prayer before the doors are shut. In Hassidic teachings, the Neila is viewed completely differently—it is the most cherished [...]

The Offering of the First Fruits and Loop Quantum Gravity

. . . Thou shalt take of the first of all the fruit of the ground, which thou shalt bring in from thy land that the Lord thy G‑d giveth thee; and thou shalt put it in a basket and shalt go unto the place which the Lord thy G‑d shall choose to cause His name to dwell there. . . . And the priest shall take the basket out of thy hand, and set it down before the altar of the Lord thy G‑d.Deuteronomy 26:2,4 And He garbed Himself with righteousness as a coat of mail, and a helmet of salvation upon His head . . .Isaiah 59:17 The Torah portion Tavo begins with the commandment of the offering of the First Fruits (bikkurim). The simple meaning of this mitzvah is self-evident. [...]

The Paradox of Steven Weinberg

The world has lost one of the greatest theoretical physicists of our time—Steven Weinberg (1933–2021). I never met him in person. But I studied his textbooks at university. His Gravitation and Cosmology, translated into Russian, was one of the few books I brought with me when we left the Soviet Union in 1982. This book is still on my shelf. Weinberg’s contribution to physics was enormous. His electroweak theory earned him a 1979 Nobel Prize in physics (which he shared with Abdus Salam and Sheldon Glashow). His work played an essential role in laying the foundation for the Standard Model of particle physics. He made significant contributions to the theory of strong nuclear forces, formulating the quark theory of strong interactions called “technicolor.” His idea of effective field theory changed our understanding of [...]

The Genetic Alphabet Has Nothing to Do with the Name of G‑d… Other Than That Everything Has to Do with the Name of G‑d

On this blog, we search for structural parallels between the Torah and science; we look for scientific metaphors that help us to understand the Torah better; and we look for Torah insights to help us understand science more deeply. However, this endeavor is fraught with peril. Using superficial parallels that don’t hold up under scrutiny serves neither the Torah nor the science and likely discredits this interdisciplinary research. I don’t like to criticize others, as my own work is not free from errors. But I feel compelled to sound a cautioning note. One such unfounded “parallel” that has troubled me for years is the purported analogy between the four bases (“letters”) of the genetic code and the four letters of the Tetragrammaton—the proper name of G‑d. This parallel, advocated by some highly intelligent [...]

A Wheel Within a Wheel

Now as I beheld the Chayot [living creatures], behold one Ophan [wheel] at the bottom hard by the living creatures, at the four faces thereof. The appearance of the Ophanim [wheels] and their work was like unto the colour of a beryl; and they four had one likeness; and their appearance and their work was as it were a wheel within a wheel. . . . As for their rings, they were high and they were dreadful; and they four had their rings full of eyes round about. Ezekiel 1:15–18 One of the most difficult theological questions is how Eternal G‑d relates to the world created by Him, the world that is always in flux. Indeed, the prophet Malachi says in the name of G‑d: For I the Eternal change not.Malachi 3:6 G‑d does [...]

Lag BaOmer Tragedy

A day of joyful festivities turned into a day of tears and mourning. When tragedy strikes, it is not the time for analysis or finger-pointing. Rather, it is the time to bury the dead and to mourn. It is the time to comfort families of the deceased. it is the time to pray that those who survive may fully recover. However, the tragic irony of this disaster is that it happened to the devout who came to the kever (burial place) of Rabbi Shimon bar Yochai, known as the Rashbi, the second-century tana, to pray for miracles. It happened on Lag BaOmer—the day of the Rashbi's passing, a day believed to be an auspicious one to pray for miracles. How does one explain to children that people who came to the tomb of [...]

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.
