Is Your Brain a Quantum Computer? (A Scientific Explanation for the Soul and Afterlife)

This week’s parasha, Chayei Sarah, begins with the passing of the matriarch Sarah. The Torah states that “the lives of Sarah were one hundred years, and twenty years, and seven years…” Traditionally, two big questions were asked of this verse: the first is why the Torah describes her life as one hundred, twenty, and seven years instead of simply saying that she was 127 years old when she died. The second is why the Torah says these were the lives of Sarah, instead of life in the singular, especially in light of the fact that the parasha actually describes her death, not life!

The classic answer to the first question is that Sarah was as beautiful at 100 as she was at 20, and she was as pure at 20 as she was at 7 years old. The answer to the second question, as we’ve explored in the past, is that Sarah (or a part of her soul) was immediately reincarnated in Rebecca, and thus Sarah’s life and life’s work continued with her future daughter-in-law. In general, the word for “life” in Hebrew is in plural, chaim, which alludes to the fact that there are really two lives: the transient life in this current physical world, and the everlasting life of the soul.

Today, many question (or outright reject) the possibility of an afterlife. Such people argue that there is no evidence or scientifically plausible explanation for such things. When the body dies, the person dies with it, and that’s it. In reality, there is a great deal of evidence to support the notion of a soul and an afterlife, and even one solid scientific explanation that is slowly gaining popularity and acceptance.

The Quantum Brain

Although there have been millions of cases of “near death experiences” and medically-induced “clinical deaths”—many of which end with the victim or patient describing other worlds and relating accurate information that would have been impossible for them to know—these are all relegated to “anecdotal evidence” and generally not taken seriously in the scientific community. We can put all of that aside (together with countless people’s personal stories of prophetic dreams and premonitions, “out-of-body” experiences, miraculous occurrences, and other inexplicable phenomena), and focus strictly on accepted science.

In recent decades, neurologists studying the human brain have sought to uncover what it is that generates consciousness and actually makes the brain work. Why and how is it that this network of cells produces a “mind”? Biology and chemistry have given us the general mechanisms of electrical signals and neurotransmitters, but have not been able to answer the real fundamental questions. To solve the mystery actually requires the most complex of sciences: quantum physics.

In 1989, world-renowned physicist Sir Roger Penrose published The Emperor’s New Mind in which he argued that classical physics simply cannot explain consciousness, nor can the brain be compared in any way to a typical computer, or be explained with familiar algorithms. Penrose suggested that the only plausible explanation for consciousness can come from quantum physics.

To go into the major principles of quantum physics is far beyond our scope. Indeed, one of the great quantum physicists, Richard Feynman, once noted: “I think I can safely say that nobody understands quantum mechanics.” Suffice it to say that quantum physics has completely revolutionized science and our entire understanding of reality. It has turned the universe into a funky place where just about anything is possible, and where things at the sub-atomic level behave in totally bizarre ways. Niels Bohr, one of the early quantum physicists (and a Nobel Prize winner) offered that “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.” Meanwhile, the man who is often called “the father of quantum physics”, Max Planck, stated:

As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.

From his lifetime of studies, Planck concluded that reality as we know it doesn’t exist, and all of matter is held together by some kind of universal mind or consciousness. Building on these ideas, and the complex math and science behind them, Penrose proposed that the brain is a “quantum computer” of sorts, and may be intricately linked to the very fabric of the universe.

Quantum Biology and the Soul

Penrose’s hypothesis inspired a psychology professor in Arizona named Stuart Hameroff. As a practicing anesthesiologist, Hameroff knew that anesthesia works by shutting down small proteins inside neurons called microtubules, and this shuts off a person’s consciousness. Penrose and Hameroff teamed up to continue researching the possibility of the brain as quantum computer. Incredibly, their conclusions suggest that the brain can actually store its quantum information in the universe itself, so that even if the brain was to die, its information would not die with it. That information can be held indefinitely in the universe, and can return to a revived brain, or even into another brain. This would explain near death experiences and clinical deaths, and provides a scientific explanation for reincarnation and a life after death. The death of the body does not at all mean the death of the person, or that person’s memories and thoughts.

While there are those who are quick to criticize the theory and reject it, no one has been able to actually refute it. In fact, since the theory was first proposed, more and more evidence has accumulated to support it. In 2014, quantum biologist Anirban Bandyopadhyay (based in Japan’s National Institute for Materials Science and a visiting professor at MIT) successfully demonstrated the quantum activity of microtubules.

It appears that science has finally discovered the soul. There are now valid, empirical evidence-based theories to explain the existence of an eternal mind or spirit, a universal consciousness, the possibility of an afterlife and reincarnation. The scientific community needs to stop aggressively denying anything that seems “spiritual”, and instead delve deeper into this exciting and promising new field. This sentiment was already expressed long ago by Nikola Tesla, considered by many to be the greatest scientist of all time: “The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence.” It was the genius Tesla who first noted that his brain “is only a receiver,” and stated that “In the Universe there is a core from which we obtain knowledge, strength, inspiration. I have not penetrated into the secrets of this core, but I know it exists.”

How Did Adam Live 930 Years?

This week’s parasha is Vayelech, which begins with Moses’ statement that “Today I am one hundred and twenty years old” (Deut. 31:2). It was the 7th of Adar, Moses’ birthday, and also his day of passing. Moses goes on to conclude his final speech to the people, then sings a deeply prophetic farewell song in next week’s portion Ha’azinu, followed by his blessings to the people in the last parasha of the Torah, V’Zot HaBracha.

Moses was the greatest of all prophets, the humblest man to walk the earth, and the central founding figure of Judaism. He was blessed with living a full and healthy life spanning exactly 120 years. It has become common today for people to wish each other 120 years of life. Why is this the specific figure? Can humans not live longer? Don’t we see in Genesis that Adam lived 930 years, Noah lived 950 years, and Methuselah (Metushelach) lived a record 969 years? What happened?

The Flood Generation

Ten generations from Adam, the world had descended into endless sin and immorality. God decreed that man’s days “will be numbered at one hundred and twenty” (Genesis 6:3). Many believe this to mean that God decreed humans will no longer be able to live past 120 years. Indeed, when looking at modern records of longevity, the vast majority of the world’s oldest people die close to 120 years. There has only been one official case of anyone exceeding 120, a Frenchwoman named Jeanne Calment who lived 122 years.

However, the traditional Jewish interpretation is that the Genesis verse above does not mean man is unable to live past 120. After all, our forefathers Abraham, Isaac, and Jacob lived long after this decree, and they lived 175, 180, and 147 years, respectively. Rather, the Jewish Sages state that God decreed the arrival of the Great Flood 120 years hence. God gave mankind 120 years to repent, and possibly avert the Flood. Noah was commissioned to go around and inspire people to mend their ways, and he had 120 years to do it.

Unfortunately, Noah failed in this endeavour, unable to bring even a single person to righteousness (as the Ark only carried his own family at the end). This is one reason for why the Flood is known in Hebrew as mabul Noach, literally “Noah’s Flood” (or mei Noach, “Noah’s waters”), as if he was partially responsible for not doing enough to inspire people to change. Because of this, many (including Rashi) have commented on the verse “Noah was a righteous and pure man in his generation” (Genesis 6:9) to mean that Noah was only righteous in his faulty generation. Had he lived in another generation, such as that of Abraham, he would not have been deemed so righteous!

We see from the Biblical chronology that after the Flood, people’s life spans steadily shorten. Moses’ older siblings Aaron and Miriam lived 123 and 126 years. Moses died at 120, and this appears to have become the new limit. After Moses, there are only a few people noted to have lived longer, one of which is Yehoyada the High Priest, who lived 130 years (II Chronicles 24:16).

What accounts for this steady degeneration in longevity?

Yeridat HaDorot

The Talmud (Shabbat 112b) states: “If the earlier [scholars] were sons of angels, we are sons of men; and if the earlier [scholars] were sons of men, we are like asses…” This is one of many passages that attests to the well-known concept of yeridat hadorot, “the descent of the generations”. It is said that each passing generation falls lower and lower in its wisdom and spiritual greatness. This concept can solve the puzzle of longevity.

The body is a finite lump of matter. It is only animated and vitalized by the infinite soul within it. Thus, the greater the soul, the longer the body can live. As the spiritual potential in each generation falls, so too does the lifespan.

Moreover, it is taught that Adam contained essentially all of the souls of humanity within him (Sha’ar HaGilgulim, ch. 11). As more and more people were born over the centuries, this single universal soul broke down further and further into smaller and smaller fragments. With the exception of a number of “new souls”, the vast majority of the world’s 7 billion people are all parts of the soul of Adam. It is therefore not surprising that today’s spiritual capabilities (and with that, the lifespans) are severely limited.

At the Speed of Light

Science may offer another intriguing possibility. According to modern physics, time as we know it doesn’t really exist. The universe is one interwoven fabric of both time and space. The faster one moves through space, the slower the effects of time for that person. There is actually a formula to measure the impact of this time dilation, known as the Lorentz transformation. It is given by the equation ΔT = t√1-v2/c2, where v is one’s speed and c is the speed of light.

Theoretically, the speed of light is the absolute maximum in our universe. At light speed (just under 3.00 x 108 m/s, or 300,000 km/s), time will totally stop for the traveller (if plugging it into the formula, one gets a value of zero). This seems impossible. However, if we plug in a value very close to light speed, such as 2.99 x 108 m/s, we get a very interesting result.* A person who has perceived living 80 years will have actually lived 980 earthly years! That makes Adam’s 930 years a more palatable 76, and Methuselah’s record 969 as 79. This fits in well with the verse in Psalms that a normal lifespan is 70 to 80 years (Psalms 90:10). But how could Adam and Methuselah have lived at near-light speed?

Beautifully, the Sages teach us that Adam was not a human like us. In many texts (such as Bereshit Rabbah 20:12), Adam is described not simply as a being of flesh, but rather as a being of light. Though most will interpret this metaphorically, there are those sages, such as the Arizal (for example, in Sefer HaLikutim, Bereshit, ch. 3) that interpret this quite literally. It remains to be seen what this means exactly, and if it has anything at all to do with physics, but perhaps there is much more to the idea of Adam being a man of light than we can imagine.

*To be fair, choosing a value such as 2.99 x 108 m/s may be deemed quite arbitrary. One can also plug in finer values even closer to the speed of light, such as 2.997 or 2.9972, and so on, each of which would give a more refined result. The point of this exercise is simply to illustrate the relativity of time, and what might explain the difference in perceived years between our generations and those of the first people, through a scientific perspective.

Noah’s Ark: The World-Altering Power of Speech

One of the more mystical lessons that the parasha of Noach highlights is the tremendous power of speech. On the simplest of levels, we are taught that Noach built an ark of wood and housed all of the creatures within it. The dimensions of this ark were apparently 30 cubits high, 300 cubits long, and 50 cubits wide (Genesis 6:15). This ark is described in Hebrew as a tevah (תֵּבָה). However, the term tevah also has another meaning: “word”.

Incredibly, Rabbi Yitzchak Ginsburgh points out that the dimensions of the ark correspond to the Hebrew letters lamed (ל, which has a numerical value of 30 in gematria), shin (ש, with a value of 300), and nun (נ, with a value of 50), which together combine to form the word lashon (לשן), meaning “tongue” or “speech”. Could it be that by telling us the ark is a tevah, or “word”, and that it had the dimensions of lashon, or “speech”, the Torah is hinting that Noach built it simply by speaking it into existence?

However it may have been, at the very least we can derive a profound lesson here: speech has the potential to affect the world around us. Our words directly impact our reality; they can create and destroy. After all, God created the entire universe through speech. He literally spoke everything into existence! (“And God said, ‘Let there be light’”.) And then He created us in His image—not a physical image, but a certain Divine potential to act as He does. God creates through speech, and so do we.

Speaking Our Minds

What we say usually reflects what we think. Our words are crafted in our minds, then released into the world. We “speak our minds”, as it is often said.

Quantum physics has already shown the powerful effect that our minds have on the universe around us. For example, the famous double-slit experiment proved that an observer influences the fundamental nature of the particles around them. More recently, noted scientists Sir Roger Penrose and Stuart Hameroff have put forth a theory for the brain as quantum computer, with our minds linked to the universe around us. It is no wonder that Nobel Prize winner Max Planck, nicknamed “the father of quantum physics”, once said:

As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.

The mind is the matrix of all matter. Our minds, more than anything else, plant the seeds that germinate into the world around us. And our minds think in words. The ability to speak is the simplest and most direct way to translate our thoughts into the real world. Speech is a conduit that connects our immaterial thoughts with the material world around us.

In the same way that God created all things through speech, the Torah teaches us that we, too, can create (or destroy) our reality in a similar manner. We may now see a new dimension in King Solomon’s adage that “Death and life are in the hand of speech” (Proverbs 18:21). It should remind us how careful we must be with what comes out of our mouths. And it should remind us to focus our efforts on using only positive, constructive, and pure speech.
