Abraham’s Stardust Children

In this week’s parasha, Lech Lecha, God forges a covenant with Abraham and promises Abraham that his offspring will be as numerous as the dust of the earth (Genesis 13:17) and the stars of heaven (15:5). The Midrash (Lekach Tov) comments on this by stating that “So, too, are [Abraham’s] children: When they rise, they rise as high as the heavens; when they fall, they fall as low as the dust.” Israel is compared to both stars and dust simultaneously. Peering a little further, there is actually a much more profound, scientific connection hiding in this statement.

According to modern scientific understanding, the dust of the earth and the stars of the cosmos are intricately linked. Where did the dust of the earth come from? For that matter, where did all elements of Earth, and its entire mass of material, come from? The scientific answer may at first sound blasphemous, but actually fits neatly with the Torah and the ancient teachings of our Sages. Scientists believe that Earth (and the entire Solar System) formed about 4.5 billion years ago (on the issue of the age of the universe, see here), probably from the remnants of a previous star that exploded in a massive supernova. The supernova resulted in a nebula of dust and gas, that then reformed into new worlds.

Going back to the very beginning, the first element to form in the universe was simple hydrogen, with just one proton and one electron. It remains the most abundant element in the cosmos. In our sun, hydrogen atoms fuse together under immense pressure to form helium, the second element (with two protons and two neutrons). Eventually, as hydrogen will start to run out, even helium atoms will start participating in fusion. This will give birth to the first and lightest metal, lithium (three protons), and then beryllium (four protons), and so on. This process generally keeps going until iron (26 protons), the most stable atom and most abundant metal in the universe. When a star explodes, or when neutron stars merge, even heavier elements may be generated, including gold and silver.

As such, it is believed that planet Earth condensed from the minerals spewed out of an exploding star long ago. The lithium and iron we mine from the ground were once part of a star! In fact, the very atoms that make up our bodies were once part of the stars, too! The Torah tells us that the body of Adam was made from the dust of the earth (Genesis 2:7), yet the dust of the earth itself was forged in the stars. With that in mind, we can have quite a literal understanding of God’s statement to Abraham that his children are both dust of the earth and stars of heaven. It also allows us to appreciate the ancient mystical teaching that man is an olam katan, a “mini-universe” or microcosm of the universe (see, for instance, Zohar III, 33b, Ra’aya Mehemna) while the universe is, in turn, an adam kadmon, a “primordial man”.

The big question is: what do we make of these scientific statements? Might they be true? Could Earth have formed from the destruction of previous worlds? Amazingly, our Sages taught exactly that!

Disorder to Order

The Torah states that before God created our world, space was tohu v’vohu and a tehom, a chaotic and unformed abyss. What does this really mean? King Solomon stated in Ecclesiastes 3:11 that God “made everything precisely at its time; even the world…” [gam et ha’olam] In the Midrash, Rabbi Tanchuma explains that this means even the Earth had a specific time when it could be created (Kohelet Rabbah 3:11). Rabbi Abahu then teaches: “We learn from this that the Holy One, blessed be He, would create worlds and destroy them, create worlds and destroy them…” until He finally made a world that “pleased” Him. Rabbi Elazar concludes by suggesting this is alluded to by the great tehom before Earth’s formation, and says this is why God ultimately stated that everything He made was “very good”. God was finally satisfied!

Thus, long ago our Sages already taught what modern science has recently come to realize: our Earth itself was made from the remnants of previous worlds that God had destroyed! It is amazing to think that the wedding ring on your finger—meant to symbolize an eternal bond—is made from gold atoms made by God billions of years ago in a massive cosmic blast, or that the iron coursing through your veins was forged by God in the furnace of an old star. It gives such things immensely more meaning.

On that note, it is important to remember that God programmed the universe with certain unyielding natural laws (as stated, for instance, in Jeremiah 33:25). And God generally follows His own rules, working through derekh hateva, “natural ways”, as our Sages taught. It therefore isn’t surprising that He also generated all the many worlds of the universe through natural means.

Intriguingly, the last Mishnah in the tractate Uktzin famously states that God made 310 worlds for each tzadik, to be enjoyed in the World to Come. This is based on Proverbs 8:21 where God promises He will reward those who love Him with yesh (יש), “substance”, the value of which is 310. It is also God’s “gift” to the righteous, since the value of “gift”, shai (שי) is 310. Going back to the Midrash above, our Sages imply that God made a multitude of worlds that pleased Him, not just the one which we inhabit now. This is probably referring to all the wonderful worlds He made—through derekh hateva, the laws of nature—for the righteous, 310 each, to inhabit in the future. And for those who like gematria, it is fitting that the value of derekh hateva (דרך הטבע) itself is 310!

A final thought: what can we learn from the notion that Abraham’s offspring are both dust of the earth and stars of heaven? Or, in other words, as the old saying goes, that “we are stardust”? We can learn from this that even if we see ourselves as minute and insignificant, a fleck of dust in the vastness of space, God nonetheless always sees us as His precious, glowing stars.

Shabbat Shalom!

Israel and the Iron Age

In this week’s parasha, Ekev, Moses describes the rich land of Israel and says it is “a good land, a land with brooks of water, fountains and depths, that emerge in valleys and mountains, a land of wheat and barley, vines and figs and pomegranates, a land of oil producing olives and honey…” This first part of the description is well-known, and the source for the Seven Species of Israel. These are the seven plants that are particularly praiseworthy, and are native to the Holy Land: wheat, barley, grapes, figs, pomegranates, olives, and dates (which were used to make the honey that Moses is speaking of). The Zohar explains that all other species of plants have various angels appointed over them, but God alone oversees the growth and flourishing of the Seven Species (see Zohar Chadash on Ruth, 106a).

What we often overlook is the next part of Moses description: “a land in which you will eat bread without scarcity, you will lack nothing in it, a land whose stones are iron, and out of whose mountains you will hew copper.” Moses promises the Israelites a land full of iron and copper. This statement is actually just as significant as the Seven Species! What is so special about iron and copper that it was so enticing for Israel? Continue reading →

Why Kiddush on Wine?

In this week’s parasha, Nasso, the Torah commands that a nazir is to abstain from wine and any other grape products. Wine appears frequently in the Torah, and plays a huge role in Judaism. Every Shabbat and holiday is ushered in with kiddush on wine, and concludes with a wine havdallah. Every wedding has a blessing on wine under the chuppah, as does a brit milah, and in ancient times wine libations were brought in the Temple. What makes wine so special?

The numerical value of “wine” (יין) is 70, a most significant number. It reminds us of the seventy names of God, of the seventy root nations of the world, and the seventy “faces” of Torah understanding. Our Sages famously stated that nichnas yayin, yatza sod, “when wine enters, secrets come out”. More than a simple proverb, it is a mathematical equation since the value of “secret” (סוד) is also 70. So, as seventy comes in, seventy comes out. On the surface level, the statement means that alcohol makes a person more likely to spill their secrets. On the deeper level, though, the Sages meant that one who drinks wine may be able to enter a mental state where they can uncover the secrets of Torah, and see it through all seventy faces. Wine can make “a man’s mind more receptive” (Yoma 76a).

Our Sages taught that wine is unique in that it defies the natural order: whereas other things degrade over time (as encapsulated in the second law of thermodynamics, the law of entropy, that the universe always tends towards disorder), wine improves and gets more valuable over time. Wine has another incredible scientific quirk: Japanese scientists researching electrical superconductors had a party in their lab and ended up accidentally discovering that wine makes certain metals superconductive!

Superconductivity refers to the property of being able to transmit electricity perfectly with no resistance and no energy loss. Generally, superconductivity requires cooling substances to near absolute zero (-273ºC). Some substances are able to superconduct at higher temperatures, around -90ºC, but even this is far too cold to be practical. Scientists around the world are therefore on the hunt for a room-temperature superconductor which, if found, would completely revolutionize the world. It would result in dramatic energy savings, and would allow for other cool phenomena like “quantum levitation”.

The Japanese scientists found that wine makes some things superconductive, especially iron-based compounds. And red wine especially was up to seven times more effective than other alcoholic beverages. No explanation for this has yet been found. It is all the more significant when we consider the central role that electricity plays in Jewish mysticism, and that our brains literally run on electrical signalling (suggesting how wine might make our brains more receptive to Torah secrets!) and that our bodies are full of iron, which makes our blood red, too.

While all of the above is fascinating, it does not explain why wine is so prevalent in Jewish rituals, especially in the recitation of every kiddush. What is the reason for wine? Continue reading →
