When the cosmos was about to be created — the fundamental forces of nature being unified in an exceedingly hot, dense point and galaxies, stars, planets, even stable matter itself yet unformed — there was no recognizable space, no measurable time. There was no darkness over the surface of the deep because there was no deep, no surface, no over and no under. No wind hovered over any water, as there was not yet any hydrogen or oxygen, much less any combination of them in the form of water. And there was no wind, either. What there was — all that there was — was chaotic, pulsating Potential.
At some moment, for reasons yet unclear, what was began to change into what is. Gravity separated first from the combined strong nuclear and electroweak forces. Then the strong force emerged and the electroweak force devolved into the electromagnetic force and weak nuclear force. The nascent universe, still small and unbelievably hot and turbulent, was an ever changing soup of energy and sub-atomic particles. It was all good, and about to become better.
Within one second from the mystery of beginning, our mini-universe inflated, and then started to expand. Its temperature dropped from an unfathomably hot state of 100 nonillion degrees Kelvin to only one trillion degrees, but that relative cooling was sufficient for sub-atomic particles to become protons and neutrons and other heavier particles. At the three minute mark, with the temperature now down to a cool billion degrees, particles fused into atomic nuclei, mostly hydrogen nuclei, some helium nuclei and other kinds as well. This, too, was good. read more
In response to a theoretical physicist’s article regarding developments in cosmology and the then current debate about whether the universe had a finite age or was in a steady state without beginning or end, the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, initiated a brief but revealing correspondence. The correspondence was prompted by Schneerson’s deep concern over what he considered to be widespread misconceptions about science and his perceived urgent need to correct those misunderstandings. In this correspondence, Schneerson demonstrated an expected devotion to the text of the Torah and traditions relating to it, but also a certain and perhaps unexpected awareness of technical issues, for instance whether light was an electro-magnetic wave or “corpuscular” or both. More importantly, in the course of the correspondence, he articulated his approach to faith and science and what some asserted was a conflict between them.
Schneerson thought the purported conflict was the result of a misconception of the nature of science. The “sciences,” he said, “are at bottom nothing more than assumptions, work hypotheses and theories which are only ‘probable’ . . . .” By contrast, he viewed “religious truths” as “definitive and categorical.” Consequently, science could not challenge religion because “science can never speak in terms of absolute truth.” read more
Although, based on the news media, it is difficult to believe that Homo Sapiens (“HS”) have become biologically gentler, an apparent reduction in testosterone about 50-60,000 years ago led to human personalities becoming gentler and human faces becoming more feminine, according to a new study based on measurements of more than 1,400 ancient and modern skulls. This led people to have gentler personalities and to great advances in art and tool making.
The study, published in the August 2014 issue of the journal Current Anthropology, found that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming. The study’s lead author, Robert Cieri, said: The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament resulting from having a little less testosterone in action. read more

Some believers in a traditional deity deny, or at least are skeptical about, certain claims of science. The issue may be the origin of the universe in a Big Bang, the age of the universe, the nature of the evolution of life on Earth or some other proposition. In these instances, the believers see science as inconsistent with, even in opposition to, a sacred truth revealed in some literature such as the Torah, the Christian Bible or the Qur’an, and therefore should be rejected.
On other occasions, though, believers will embrace science. They will hear that the initial conditions of the universe, certain laws of nature or the location and chemistry of our planet are set within a limited range that allows for human existence — a proposition sometimes called the Anthropic Principle (i.e., relating to humankind) — and take those conditions and characteristics as proof of a personal god. They will understand a “fine-tuned” universe as demonstrating, or at least strongly implying, the existence of a Fine-Tuner, a Devine Designer. read more
From time to time, like when an itch just needs to be scratched or a roiling cauldron must overflow, essays are written and debates ensue over the question of whether there is a conflict between Judaism and science. The direct answer to the question depends to a considerable degree on how one defines Judaism, and to a lesser degree on how one defines science. But discussions about the topic, even from Jewish perspectives, often miss that basic point.
Recently Moment Magazine asked nine rabbis the following question: “In what ways, if any, do science and Judaism conflict?” The rabbis were apparently selected as representative of, though not necessarily representatives of, various orientations and denominations. Moment even ordered their responses as if there were a spectrum of Jewish thought from Independent to Humanist, Renewal, Reconstructionist, Reform, Conservative, Modern Orthodox, Orthodox, and, ultimately, Chabad. (Parenthetically, whether this means that Moment believes that Reform is at the center of Jewish opinion is unknown.) The rabbis’ responses are illustrative of the problem inherent in these kinds of discussions. read more
Religion is not a maladaptive “illusion” (Freud), nor is religion a manipulative “opiate” (Marx). Religious behavior is a ubiquitous biological adaptation rooted in Homo Sapiens, because religion like intelligence and language helps human communities survive. Religion, like intelligence and language, can be used for both good and evil purposes, but this is also true of culture, science, politics and all other important human activities. Since almost all revealed religions teach that humans have a pre-birth soul that predisposes them to respond to a Divine call even before the revelation occurs, I identify the existence of a biologically based, self-conscious spiritual soul with the evolution of Homo Sapiens spirituality.
A reference to a prescriptural, prehistoric period when spiritual evolution was unaided by God appears in the book of Genesis (4:26) where it states, “At that time humans began to invoke YHVH by name.” Most of the rabbinic commentators translate the verb hukhal to mean ‘profane’ taking this as a negative statement. But ‘began’ is the more normal meaning of the verb. The Torah asserts that prior to Enosh humans did not practice religion based on the divine insight of revelation (i.e., “invoke YHVH by name”) that they were able to do later. Mystical and spiritual experiences were interpreted by human intelligence without the benefit of prophetic revelation. In the spirit of this Torah insight I offer the following account of the evolution of pre-historic human spirituality. read more
In the great satirical movie Duck Soup (first released 79 years ago to the date of this post), Mrs. Gloria Teasdale (Margaret Dumont), the financial underwriter of the nation of Freedonia, recruits Rufus T. Firefly (Groucho Marx) to be the insolvent country’s new president. The opposition then retains two spies, Chicolini (Chico Marx) and Pinky (Harpo Marx), to work for them. Toward the end of the film, in a bedroom scene with Teasdale, the spies both dress like Firefly in order to secure the combination to a safe. After she gives the combination to one Firefly (the disguised Pinky), Mrs. Teasdale watches him leave the room, but suddenly another Firefly (the disguised Chicolini) appears. Teasdale confronts Chicolini who denies leaving and blusters “Well, who you gonna believe, me or your own eyes?” He knew that Teasdale had convincing evidence against him. She was, after all, an eye-witness. And yet, she did not understand.
Perhaps more than on any other of our senses, humans rely on sight. Our camera eyes allow massive amounts of information to enter our brain, first through the lens at the exterior of the eye, and then from the inverted image on the retina at the back of the eye by way of the optic nerve. In the plains of Africa, our ancestors stood to gather information about their surroundings. Today we focus on ironically named smartphones, not so much to hear audio transmissions, but to stare at screens with text or other visual data.
So important is sight to us that over two-thirds of the sensory cells in our bodies are the light sensing cells in our eyes. So energy consuming is the human retina that it uses more oxygen per gram than does the brain. (Shubin, Your Inner Fish (Pantheon Books 2008), at 150; Lane, Life Ascending (W. W. Norton 2009) at 175.) read more

Rabbi Moshe ben Maimon, Maimonides, also known by the acronym Rambam, lived just over eight hundred years ago (1138-1204 CE). He never saw the planet Earth as astronaut William Anders did on December 24, 1968 when module pilot Anders took the now iconic photograph above while flying over the lunar surface during the first manned orbit of the Moon. We do not know if Maimonides even imagined such a sight.

The picture above shows Earth with the Moon in the background. This scene was captured by the Galileo Orbiter on December 16, 1992 at a distance of almost four million miles from our home planet. Maimonides never had the opportunity to see Earth and Moon from this perspective either.

Living some four hundred years before Nicolaus Copernicus considered the nature of the solar system and Galileo Galilei fashioned his first telescope, Maimonides did not realize that the Earth circled the Sun, and not the other way around as was commonly understood in his day. Nor could he have known that the Sun was but one medium sized star in a rather unremarkable galaxy known as the Milky Way which spans 100,000 light years and is similar in size and shape to the spiral galaxy NGC 3370 shown above in a picture taken by the Hubble Space Telescope. Similarly, he would not have known either that our galaxy consisted of a few hundred billion stars, give or take, or that the Milky Way was but one of perhaps a hundred billion galaxies, give or take, in the visible universe.

In two prior posts, we have reviewed Dr. Gerald Schroeder’s strange claim in The Science of God (“TSOG”) (Rev. Ed. 2009) that billions of years of cosmic evolution and six biblical days of creation actually occurred simultaneously. With his self-imposed standard of not bending the Bible to science or science to the Bible in mind, we have analyzed how objective Schroeder actually was with respect to the Bible and science. In both instances, we have found Schroeder’s work sorely lacking. He has failed to meet his own standard and other more objective ones as well. read more
