Big Bang

  Torah starts with two words – Bereshit bara… Bereshit in Hebrew mean “in the beginning” and bara means “created.” What is interesting is that both words begin with the same letter Bet pronounced as “b”. Another expression made of two words that describes the process of creation is Big Bang. And these two words also start with letter “b”. It could, of course, be a coincidence, but not according to Nahmanides (Rabbi Moses ben Naḥman Girondi know by his acronym as the Ramban, 1194–1270). Here is Nahmanides’ description of initial moments of the creation: …At the briefest instant following creation all the matter of the universe was concentrated in a very small place, no larger than a grain of mustard… From the initial concentration of this intangible substance in its minute location, [...]

The Fifth Force

“Now therefore write ye this song for you, and teach thou it the children of Israel.” Deut. 31:19 The four known fundamental forces are: gravitational force, electromagnetic force, strong (nuclear) force and weak (betta decay) force. Newton first described gravitational force in his famous universal law of gravity. Today, we use Einstein’s General Theory of Relativity to describe strong gravitation fields. Electromagnetism was described in the 19 c. by Faraday and Maxwell. Strong and week forces were discovered much later, in the second half of the 20 c. Since Albert Einstein started a search for a unified field theory, unsuccessfully trying to unify (describe by a single theory) gravity and electromagnetism, the quest for a unified field theory – the “Theory of Everything” – became the holy grail of theoretical physics. Strong and [...]

Adam Kadmon and Holographic Universe

Dedicated to the memory of Professor Yaakob David Bekenstein   The Torah opens with the word “Bereshit” – in the Beginning – whose first letter, Bet, is written large to signify that it contains a hidden meaning. The gematriah (numerical value) of the letter Bet is 2. It has three sides – top (“roof”), bottom (“floor”) and the right “wall”:   Letter Bet of Bereshit may be viewed as the “event horizon” of the Torah. In General Relativity, the event horizon is the area of spacetime beyond which information is inaccessible to an outside observer. For example, the event horizon of a black hole is the boundary surrounding every black hole that acts as information firewall – the light from within the event horizon cannot escape outside and, therefore, information is invisible to an [...]

The Entangled Twins

Entanglement is often called the most baffling and the most quintessential aspect of quantum mechanics. What is entanglement, in a nutshell? Two particles born out of one reaction (or two particles that interacted through a collision) remain connected, no matter how distant from each other. A change in the status of one particle instantaneously causes a change in the status in the other particle. Einstein called it "spooky action at a distance." Entanglement is often associated with certain symmetry and corresponding laws of conservation. For example, the law of conservation of angular momentum requires that the spin (the quantum-mechanical analog of the angular momentum) of two entangled particles always point in the opposite directions. This means that, if two entangled particles have their spin in a state of superposition of Up (↑) and Down (↓) and we collapse [...]

Maarat HaMachpelah – Double Cave

Chayei Sarah Give me the Machpelah (double) Cave — וְיִתֶּן לִי אֶת מְעָרַת הַמַּכְפֵּלָה Bereshit-Genesis 23:9 The first legal acquisition of land in Israel takes place when Abraham purchases a double cave – Maarat HaMachpelah – in the city of Chevron (Hebron) as an ancestral burial plot. Rashi explains that the cave was called Machpelah (i.e., double) because it had two structures – an upper chamber and a lower chamber. (Another explanation given in the Talmud relates the name of this cave to four couples buried there – Adam and Chavah (Eve), Avraham (Abraham) and Sarah (Sara), Yitzchak (Isaac) and Rivkah (Rebecca), and Yaakov (Jacob) and Leah.) A Medrash explains that the reason this cave had two chambers – the upper and the lower – is because it reflected the structure of Gan Eiden (Paradise — the Garden of Eden), [...]
