Gravitational Waves – Listening to Chirping of the Cosmos

Gravitational waves discovered last year and announced last week are converted into sound waves giving the astronomers the ear into the cosmos. Characteristic sounds of gravitational waves are called “chirping.” In Hebrew the  word for bird is tzipor – “chirping.” King Solomon was said to have understood the language of birds. Listening to and understanding the chirping of birds has been a long tradition among prophets of Israel. Tradition has it that Baal Shem Tov listened to and understood the chirping of birds. Rabbi Chaim Vital, the principal disciple of the Ari-zal, writes in Ruach HaKodesh, “Every animal, beast, bird, and creeping-crawly is empowered by a spirit. These spirits are keepers of great mystery. Therefore, through a chirp of a bird, for example, or the sound of any animal, one can also discover [...]

Black Holes and Gravitational Waves

A hole in Kabbalah is called “rah” (evil). The reason for that is, as content is lost due to a leakage through the hole, forces of evil get their nourishment from leakage of light. Kabbalah views the world as divided into two domains – a domain of holiness (“sitrah d’kedushah”) and a domain of evil, so-called "the other side" (sitrah acharah). A hole is viewed as a portal from the domain of holiness into the other side – the domain of evil. This is why, for example, we are commanded to attach mezuzot to the doors of our houses. Doors viewed as portals of evil, through which good energy of the house can leak into the outside – the domain of evil. The mezuzah containing the affirmation of the oneness of God, plugs these [...]

When was the World Created?

There is a dispute in the Talmud as to when was the world created. According to Rabbi Eliezer, the world was created in the month of Tishrei. According to Rabbi Yehoshua, the world was created in the month of Nisan (Tr. Rosh Hashanah (10b)). The Chasidic thought attempts to reconcile these opposite opinions suggesting that both opinions are correct—the world was created in Nisan in thought, whereas in deed, it was created in Tishrei. The problem with this approach is that for halakhic (Jewish ritual law) purposes of calculating Jewish calendar, the planets are deemed to have commenced their heavenly orbits in Nisan, not in Tishrei! How could planets that haven’t yet been actually created, start their orbital movements in Nisan?! This can be explained by using the approach I suggested in my post [...]

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 [...]

Two Beginnings

Two Beginnings B’reshis bara Elokim es hashamaim v’es haaretz… In the beginning G-d created heaven and earth… Alternative translations: With two beginnings G-d created heaven and earth… Genesis 1:1   *This is an abridged and updated version of the paper “Towards Reconciliation of Biblical and Cosmological Ages of the Universe” Presented at the Third Miami International Conference on Torah & Science in Dec. of 1999 and published in B’Or HaTorah, 13 (2002) p. 19.   Contemporary science places the age of the universe in the thirteen to fourteen billion years range, or 13.799 ± 0.21, [1] to be precise.  This age is derived from both theoretical models as well as experimental data.  (For an overview of theoretical and experimental approaches to dating the universe and our planet Earth see my original paper TOWARDS RECONCILIATION OF BIBLICAL AND COSMOLOGICAL AGES OF [...]

On the Age of the Universe in the Many-Worlds Interpretation of Quantum Mechanics

On the Age of the Universe in the Many-Worlds Interpretation of Quantum Mechanics[*]  Alexander Poltorak    Abstract   The present paper addresses the apparent discrepancy between the cosmological age of the universe, estimated at twelve to fourteen billion years, and the “biblical” age, believed in the Jewish tradition to be less than six thousand years.  This paper is a sequel to my previous paper, "On the Age of the Universe," presented at the Third Miami International Conference on Torah and Science, which aimed to resolve this contradiction from the point of view of the collapse of the wave function in the Copenhagen interpretation of Quantum Mechanics (QM). Continuing this discussion, I shall now approach the problem from the slightly different point of view of the many-worlds interpretation of QM.     This paper [...]

On the Nature of Time and the Age of the Universe

Presented at the International Torah and Science Conference in Miami International University on December 18, 2005 Alexander Poltorak   Introduction. This is the third in a series of articles, in which I attempt to sketch various approaches to reconciling a cosmological age of the universe currently estimated at 13.75 billion years with the Jewish tradition setting this age at less than six thousand years (5770 as of the day of this writing, to be exact). The first article [1] tackled this problem from the point of view of Copenhagen interpretation of quantum mechanics suggesting that there were two distinct forms of existence—physical and proto-physical—and that the first conscious observers, Adam and Eve, collapsed the universal wavefunction, bringing the world from amorphous proto-physical existence into tangible physical existence.  This approach leads to two distinct [...]

Towards Reconciliation of Biblical and Cosmological Ages of the Universe

Towards Reconciliation of Biblical and Cosmological Ages of the Universe[1] Alexander Poltorak   Abstract Two opposite views of the age of the universe are considered.  According to the traditional Jewish calendar based on the Talmud the age of the universe is less then six thousand years.  The cosmological models of the universe supported by the abundant empirical data place the age of the universe in the twelve billion years range.  Critical examination of both views is presented in the first part of the paper.  In the second part, we consider quantum-mechanical state of matter before and after the introduction of a conscious observer.  Role of the observer’s free will is examined.  The definitions of physical and proto-physical states of matter are proposed.  It is suggested that creation of the first conscious being with [...]
