Cosmic Parallels of Hinduism

The most beautiful and deepest experience a man can have is the sense of the mysterious. It is the underlying principle of religion as well as all serious endeavors in art and science. He who never had this experience seems to me, if not dead, then at least blind.   — Albert Einstein

Perhaps one of the most exciting — and unsettling — concepts in modern cosmology is the theory that we inhabit a parallel universe. “There are vibrations of different universes right here, right now. We’re just not in tune with them. There are probably other parallel universes in our living room — this is modern physics. This is the modern interpretation of quantum theory, that many worlds represent reality,” says Michio Kaku, professor of theoretical physics at New York University and author of Parallel Worlds: A Journey Through Creation, Higher Dimensions, and the Future of the Cosmos.

The concept of parallel universes may be novel and disconcerting to scientists, but it rests very comfortably in ancient Hindu cosmology. The Puranas, Hindu religious texts thought to date back to between 500 B.C. to 1500 B.C., are replete with descriptions of many worlds whose inhabitants are ruled by kings in the human plane and gods in a higher plane. The many gods, in turn, belong to many different worlds and planes of existence. At the highest level of the hierarchy are the trinity, namely, Brahma, Vishnu, and Mahesha, ruling the divine kingdoms. Brahma is the creator, who dreams the universe into being, which is maintained by Vishnu. What humans perceive as reality is in fact the dream of Brahma, misled by matter. Brahman (not to be confused with Brahma) is the ground of all reality and existence. Brahman is uncreated, external, infinite and all-embracing. It is the ultimate cause and goal of all that exists. All beings emanate from Brahman; all beings return back to the same source. Brahman is in all things and it is the true Self (atman) of all beings.Physicists hypothesize several levels of parallel universes. Max Tegmark, of the Massachusetts Institute of Technology, even envisions an infinite number of parallel universes: “In Infinite space, the most unlikely events must take place somewhere. People with the same appearance, name and memories as you, who play out every possible permutations of your life choices.”

The Paingala Upanishad, another religious text, describes the many worlds created by Brahman: “With those quintuplicated elements he created endless cores of macrocosms and for each of these fourteen appropriate worlds and globular gross bodies fit for each planes of them all.”

Among the many universes envisioned by physicists, one exists in extra dimensions and might be physically very close to us. As creatures of a three-dimensional world, we may not perceive it. But scientists hope that these universes might drop some clues to help us identify them, like ripples in a pond help us locate the actual disturbance. Modern scientific theories of creation and the world of particle physics help us develop a picture of our cosmos, which might be just one of many possible universes. In his best-selling series Cosmos, renowned astronomer Carl Sagan reflected on the parallels between modern cosmology and Hindu philosophy, noting: “Hindu religion is the only one of the world’s great faiths dedicated to the idea that the cosmos itself undergoes an immense, indeed an infinite number of deaths and rebirths. It is the only religion in which the time scales correspond, no doubt, by accident, to those of modern scientific cosmology .… There is the deep and the appealing notion that the universe is but the dream of the god who after a 100 Brahma years dissolves himself into a dreamless sleep and the universe dissolves with him until after another Brahma century he starts recomposes himself and begins again the dream, the great cosmic lotus dream. Meanwhile, elsewhere there are an infinite number of other universes each with its own god dreaming the cosmic dream.”

Vedic cosmology has scores of other eerie parallels with some of the most cutting edge recent cosmological theories of multiverse, oscillating universe, and the Big Bang, so it should come as no surprise that some of the greatest minds in science have turned to these 3,500-year-old cosmological ideas for inspiration and questions about our enigmatic universe. The Danish nuclear physicist and Nobel Prize winner Niels Bohr once wrote, “I go into the Upanishads to ask questions.”Observational evidence in support of parallel universes has come from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP). While analyzing the Cosmic Microwave Background (CMB) radiation data, scientists discovered evidence of a huge void spanning almost one billion light years (1 light year is approximately 9.5 trillion kms). The void in the infant universe represents the absence of any material, which otherwise should have become stars and planets. None of the current cosmological theories can explain such huge voids in the data. Some physicists interpret this as the unmistakable imprint of another universe beyond the edge of our own. Physicist Mersini-Houghton and her colleagues have proposed a theory of entangled universes, under which they predict two huge voids, not just one. One of them has been found by WMAP data and they expect new data will reveal a second similar void. The recently launched Planck satellite by the European Space Agency, whose exceedingly sensitive detectors measure CMB radiation and which captured its first image in early September, may be able to ascertain this second void.

The idea that all structures that exist mathematically also exist physically is the foundation of the parallel universe concept. This hypothesis, known as the “ultimate ensemble,” predicts the existence of all universes that can be defined by mathematical equations. But many physicists disagree on the ground that all mathematical structures are not well defined.Striking as these similarities are, it does not mean that modern science has vindicated Vedic cosmology. For one, these modern cosmological theories may themselves be disproved and besides, many physicists remain skeptical of these theories. Some cosmologists, for instance, question the whole notion of multiverse. According to them, if the universe encompasses everything we know or ever want to know, it rules out any room for parallel universes. Some other models suggest that universes are finite in number and restricted by mathematical formulations.

Nevertheless, the concept of many worlds or parallel universes, which would have invited the ridicule of mainstream physicists, as it did when it was first proposed more than a half a century ago by U.S. physicist Hugh Everett, is currently one of the hottest trends in theoretical physics. The multiverse theory is the inevitable result of quantum mechanics, which represents a set of multiple “probable” states for a particle. When an observation is made, the particle chooses one of the multiple states measured by the observer and the other states collapse. This is the most basic principle behind the existence of many universes or multiverses.

Erwin Schrodinger, a leading theorist in quantum mechanics, who had a life-long interest in Vedanta philosophy, wrote: “What we observe as material bodies and forces are nothing but shapes and variations in the structure of space. Particles are just appearances. The world is given to me only once, not one existing and one perceived. Subject and object are only one. The barrier between them cannot be said to have broken down as a result of recent experience in the physical sciences, for this barrier does not exist.”Quantum physics, the study of the minutest particles that make up matter, has been remarkably successful, but it reveals a picture of a quantum reality so strange that our minds are unable to grasp it. For instance, quantum mechanical experiments have proved that objective reality is unlikely to have a separate existence. The nature of the ultimate reality is intertwined with our actions and uncertainty rules when we observe it. This is contrary to our common sense view that reality has an existence independent of the observer. In the realm of the smallest particles, however, objective reality is not an absolute entity that can be measured definitely as is true in classical physics.

The absence of objective reality implies that the material world could be an illusion — or, what Hindu sages call Maya. In Hinduism, Maya is the natural illusion that the material world is the only reality. It is a skewed perception, albeit commonly held, to believe that the material world is the fundamental reality. Maya, which has its roots in the Upanishads, denotes the power of God to make human beings believe in an illusion. The material world is the manifestation of Brahman, the infinite and immortal reality that is responsible for matter, energy, space, time and every being. The scriptures and philosophies seek to unveil the illusion to learn the ultimate truth.This is not very far removed from the concept of Brahman — the self-existent, immanent and transcendent supreme and ultimate reality. Brahman is the fundamental divine cause of everything in and beyond the universe. The nature of Brahman is explained as personal and impersonal and it is the source of creation of the universe and Gods. The universe and all the objects in it are the manifestation of a fundamental reality, which science doesn’t know yet. We understand the universe as an exchange of matter and energy and scientists often disagree about the fundamental building blocks of these phenomena.

Science employs its own methods and procedures toward that goal. Our universe and its subjects are creatures of spirit coated with matter that conceals the spirit from the light. Science can demonstrate its processes, is based on rationality and logic, and can be comprehended, but we are somewhat lost in the scheme of the ancient wisdom. Consider for example, this Upanishad expression, “That which permeates all, which nothing transcends and which, like the universal space around us, fills everything completely from within and without, that Supreme non-dual Brahman — That Thou Art.”

The scientific approach always assumes that fundamental reality is different from us and we are independent observers seeking truth. But many researchers now believe that we must rethink this assumption. Our observation impacts the observed reality, because we are part of it. This essentially is the Adwaitha philosophy, a cornerstone of Hinduism, which asserts that Brahman (ultimate reality) and Atman (self) are the same. Such a non-dualistic approach is advocated by many modern researchers, who argue that the effect of observation either changes reality or creates new realities.Our interpretations of the evolution of the cosmos, once based on myths and legends, have advanced markedly in the last century. We live in a universe that is beaming with billions of galaxies that are continuously expanding. We now know that this expansion is accelerating and we will never know what is beyond our cosmic horizon as no light will ever reach us from the expanding universe. It is ironic that we need many universes for the existence of our own universe.

Human eyes operate on the visible light of the electromagnetic spectrum, allowing us to view only objects that emit light, which comprise only a small fraction of the universe. In modern times, telescopes replaced the unaided eye in the hunt for the unknown. Operating from ground and space, these telescopes scan the cosmos to draw pictures of material objects. Even with telescopes, we exploit the electromagnetic radiation to weave images of the cosmos. Whether it is gamma rays, x-rays, microwaves or visible light, throughout human history we have been dependent upon different forms of light to learn of cosmic events, which document our own history. The early universe was not transparent to light, which implies that we can write the history of our cosmos only up to the point when the first light began its journey, long after the creation of the universe. Additionally, the interaction of light with matter distorts the details of the information it carries. However, unlike light, gravitational waves propagate through cosmos without reflection or refraction. That could potentially allow us to create a pure picture of the cosmos beyond the levels light allows us.If a physical reality exists independent of human experience and that reality can only be expressed with our most logical language, mathematics, then observational science is not the only way to comprehend the ultimate mystery. This formulates the possible intersection of science, philosophy and ancient wisdom. Unlike the West, religion and science are not opposed fundamentally in Hindu traditions. Freeman Dyson, a theoretical physicist famous for his work in Quantum Field theory, says “Science and religion are two windows that people look through, trying to understand the big universe outside, trying to understand why we are here. The two windows give different views, but both look out at the same universe. Both views are one-sided, neither is complete. Both leave out essential features of the real world. And both are worthy of respect.”

The gravity wave detection is the objectives of LIGO (Laser Interferometer Gravitational-wave Observatory). Two of the biggest such interferometers in the United States — one in Hanford, Wash., and the other in Livingston, La. —are collectively called LIGO. These systems are sensitive enough to detect the ripples in the space-time fabric caused by cosmic events, such as supernova explosions, and transmitted by gravity waves. These waves carry the information of events, such as the explosion and collision of stars. It is estimated that by 2010, direct detection of gravity waves will be possible. Gravity is the weakest of all known forces in the nature and has confounded physicists for decades. Now string theorists believe that gravity may be leaking into parallel universes or other dimensions.

The Big Bang

The Big Bang, symbolizing the finite beginning of the infinite universe from a primordial hot and dense condition nearly 13.7 billion years ago, is presently the leading theory of the origin of the Cosmos, displacing another popular “steady state” model. The big bang theory is rooted in astronomer Edwin Hubble’s observations that the galaxies are expanding and moving away from each other. Evidence of the expansion was also found in the cosmic microwave background radiation captured by the Hubble Telescope in 2003. The big bang theory, formulated by George Gamow, still faces formidable challenges to meet the standards of science, but it is the best prevailing model for the universe’s origins.

“Then was not non-existent nor existent: there was no realm of air, no sky beyond it.The Hymn of Creation (Nasadiya Sukta) in the Rig Veda, written around 1500 B.C., describes similar big bang origins of the universe:

What covered in, and where? And what gave shelter? Was water there, unfathomed depth of water?
Death was not then, nor was there aught immortal: no sign was there, the day’s and night’s divider.
That One Thing, breathless, breathed by its own nature: apart from it was nothing whatsoever.
Darkness there was: at first concealed in darkness this all was indiscriminated chaos.
All that existed then was void and formless: by the great power of Warmth was born that Unit.”

The cosmological constant is one of the biggest enigmas of modern cosmology. The comprehension of the cosmological constant might successfully explain repulsive dark energy. Two scenarios have been predicted for the distant future of the universe — the Big Rip or the Big Crunch. Depending on the critical density of the universe, these are the probable future of our cosmos. Either way, the current universe will end in trillions of years to come. That inevitable fate of the universe has led cosmologists to speculate on what follows the demise of our universe.The discovery of the accelerating nature of universe’s expansion demands a force surpassing gravity and stretching the fabric of the cosmos. Physicists call it dark energy, and the big bang model predicts that the universe consists of 73% dark energy and 23% dark matter. Normal matter, which constitutes just four percent of the universe, makes up all the stars, planets and living and non-living things that are known to us. The Big Bang model needs dark energy to account for the current state of the universe, although scientists have no lucid explanation for it. In fact, scientists believe dark energy is the same as the cosmological constant originally introduced by Albert Einstein to counterbalance the gravitational attraction of matter in the universe. He later discarded the cosmological constant when Hubble’s observations proved the expansion of the universe. Now, modern cosmologists think Einstein’s cosmological constant holds the key to the accelerated expansion of the universe.

Paul Steinhardt of Princeton University and Neil Turok of Cambridge University recently proposed that the cosmological constant was once much larger, but that its value decayed with each manifestation of the universe. Their theory argues that the universe came into existence not just once, but in endless cycles of death and birth. Known as the “Cyclic Universe Theory,” it could explain the dark energy and its role in the acceleration of the universe. Because of endless cycles, the universe would be far older than the 13.7 billion years that scientists currently estimate. Steinhardt and Turok estimate that each cosmic cycle lasts about a trillion years. During this time, the universe runs its natural course, but all the while matter and energy fan out through space until they are extremely diluted. Once that happens, a cosmic collision follows, and each collision is essentially a new Big Bang that infuses the aging Universe with new matter and energy. In scientific terms, energy cannot be created or destroyed, but it can change forms and also matter-energy exchange is possible. When the current form of matter is destroyed, it can pave the way for a new form of matter or energy.

For instance, Kalpa, which is a day in the life of Brahma, is 4.32 billion years, the estimated age of Earth. By contrast, the common time scales of the universe in both Western science and religion until just a century ago, were just a few thousand years, not the billions and trillions of years envisaged by Vedic cosmology. As another example, the Surya Siddhanta, an astronomy textbook from ancient India, computed the earth’s diameter as 7,840 miles, against the modern measurement of 7,909 miles. Similar calculations of the earth-moon distance of 253,000 miles is reasonably close to the current measured distance of 238,857 miles. Surya Siddhantaalso provides close estimates of the diameters of five planets — Mercury, Venus, Mars, Jupiter and Saturn. What makes these measurements especially striking is that they are believed to have been written between 600 B.C. to 1500 B.C. That is almost 3,000 years before Nicolaus Copernicus and Johannes Kepler revolutionized Western astronomy, just by shifting from an earth-centered universe to a sun centric one.The metaphorical similarities between the newly proposed cyclic universe theory and Hindu cosmology are astounding. Hindus cosmology speaks about the universe being created, destroyed, and recreated in an eternally repetitive series of cycles. Brahma creates a new universe that would eventually be destroyed to begin another universe. According to Hindu cosmology, Brahma himself undergoes destruction after 100 Brahma years, 311 trillion years in the human scale, to pave the way for a new Brahma and thus a new universe. Gods are also subjected to the laws of nature and their lives occupy the cosmos in time scales that are comparable to the astronomical scales in such an oscillating universe.

However, remarkable as these similarities are, there are also significant departures between Vedic and modern cosmology. The Sun’s diameter (32,500 miles, according to Surya Siddhanta) is far from the modern day value of 870,000 miles. Modern science postulates that organic molecules (matter) evolved to become life and consciousness, which is fundamentally different from Hindu philosophy’s approach that they cannot evolve from matter unless matter has the inherent potential to provide life and consciousness. Furthermore, the Big Bang model proposes that the mass-energy before the universe came into being was concentrated at a single point. The Vedas, by contrast, assert that in the beginning there was no mass-energy and it was a complete void. Even the cyclic model of the universe, while bearing some similarity to Hindu cosmology, is different. The ancient model says the cycles are independent, but modern cyclic theory assumes dependence.

Nevertheless, many modern cosmologists, awakened to the limits of observational sciences, are intrigued by the cosmological visions of the Vedas and the Upanishads, even though we don’t understand the processes that yielded their cosmic insights. Perhaps the strongest symbolic acknowledgment of the parallels between modern and Vedic cosmology is reflected in the Natraja statue outside CERN, the European Organization for Nuclear Research, which has built the world largest particle accelerator, the Large Hadron Collider (LHC), 17 miles in circumference, capable of shooting particles at 99.9999% the speed of light, on the France Switzerland border. When the collider becomes fully operational in 2010, it will look for the Higgs Boson, often referred to as “God’s particle,” which is suspected to be responsible for determining the mass of a material object. The fundamental particles are mainly classified into two Fermions ( a reference to Enrico Fermi, who conducted the first nuclear chain reaction that led to the development of first nuclear bomb) and Bosons (a reference to S.N Bose, the Indian physicist who published his findings with Einstein in 1924, now known as Bose-Einstein statistics). Bosons play a crucial role of interaction between different fermions to create normal matter.

The 6 feet Natraja statue gifted to CERN in 2004 by the Indian government depicts Shiva’s dance of creation and destruction, not unlike the dance of fundamental particles that generate and destruct, manifesting the interchangeable nature of matter and energy in the universe.

A plaque next to the Shiva statue captures the modern significance of the metaphor of Shiva’s cosmic dance from Fritjof Capra’s best-seller The Tao of Physics: “Modern physics has shown that the rhythm of creation and destruction is not only manifest in the turn of the seasons and in the birth and death of all living creatures, but is also the very essence of inorganic matter and for the modern physicists, then, Shiva’s dance is the dance of subatomic matter. Hundreds of years ago, Indian artists created different forms of visual images of dancing Shiva in a beautiful series of bronzes. In our time, physicists have used the most advanced technology to portray the patterns of the cosmic dance. The metaphor of the cosmic dance thus unifies ancient mythology, religious art and modern physics.”
