12. Beauty of the Universe of Quantum Dancing

We know that the ultimate, unique source elementary particle is eluding us now that we have identified so many elementary particles (including antiparticles and super-particles): from which fundamental particle did these elementary particles emerge from ( ….) or  the source of so many particles was nothing but the infinitesimal infinitely-dense point-like energy concentrate with which the Big Bang started?

We have not yet been able to settle the issue: whether the energy concentrate was the egg and the elementary particles the eggs or the elementary particles formed the multiplicity of eggs that produced the single chicken of energy concentrate that preceded the formation of eggs. We just explored the possibility of a Nothing from which the energy concentrate emerged. But the question remained: Energy first or the elementary particles first.  The only solution is to treat them as one and the same thing in different forms.

But more perplexing possibilities haunt us in our investigation into the elementary particles. Energy is now known to be available in discrete units of one Quanta particle and not as continuous! On top of this, we have come to know that the elementary particles appear as particles or as waves depending on how to interact with them with our detecting and measuring instruments. Quantum physics deals with discrete, indivisible units of energy called quanta. Quantum Theory tells us about the behavior and characteristics of sub-atomic matter (electrons, protons and neutrons) and energy. The physical properties of the subatomic particles, like the momentum and position cannot be determined at a time. If one value is known precisely, the measurement of the other value is less accurate.

*Energy is discontinuous and exists in small packets, called quanta

* According to the Principle of Wave-Particle Duality, the subatomic particles behave as particles, as well as waves. The same “object” may appear to be a particle (locatable in a single place), or a wave, spread out over space and time (A particle is a solid object with a specific location in space and time while a wave is neither solid nor localized but spread out like a wave in water). Recent experiments assert that the elementary particles may in fact exhibit simultaneously both particle like and wave -like behavior. This duality may be arising out of Entanglement of particles: particles are never independent - they get linked

*The subatomic particles move in a random manner. Particles being in more than one place at once (a recent experiment found that one particle could be in up to 3,000 places!)  Subatomic particles seem to travel instantaneously over any expanse of space (even though Einstein said that nothing can travel faster than the speed of light) .In classical physics one could determine with certainty where a particle would go, given any set of conditions, but in quantum physics, one can never know with absolute certainty how a specific thing will turn out and can only specify probabilities of alternative locations to which a particle may shift. It is physically impossible to know both the position and the momentum of a particle at the same time. The more precisely one is known, the less precise the measurement of the other is.

*As per Heisenberg Uncertainty Principle, the process of observing appears to influence what is being observed: when the observer attempts to observe or interact with the dancing damsels of subatomic matter/ energy, the observed changes nature from being a state/wave of probability to a particle. The act of measurement is creating that very reality it is measuring. Thus, when one is not observing or measuring, the electrons or photons (particles of light) act as waves: they have no precise location, but exist as “probability fields”. But, when one is observing or measuring, they appear as particles: the probability field “collapses” into a solid object locatable in a specific place and time.

The magical dance of quantum energy is the greatest shock that science have ever experienced and enjoyed for the last eleven decades bewildering the smartest men like Einstein. When an electron moves from orbit to orbit around the nucleus, it does not move through space the way we would think, instead it moves instantaneously: it just disappears from from one place in one orbit to appear instantaneously in another place in another orbit. The best the scientists could do is give up the attempt to determine with certainty exactly where the electron would appear or jump on to but calculate the probabilities of its jumping into different alternative locations using Schrödinger’s wave equation.


Weirdness of the microscopic universe of particles is fascinating. The thoughts of the ancient Indians 4000 years back that seemed to us as unscientific and imagination of the child now seems to no longer weird. Modern scientists claim that a change in the spin of one particle in a two-particle system seem to affect its twin simultaneously even if the two are separated by great distance in space: separated articles seem to in contact despite their distance in space. There may not be any transmission of signals between different particles separated by space: information seems to get transmitted from one to the other particle. We are still able to figure out how?.
Maybe information of the entire universe is contained in each of its parts (like any part of an Hologram providing the same image of the whole hologram itself.

Finally, some elementary particles may be soon termed as fairy tales: light appears quantized only because of the way it interacts with matter and protons may not really exist.


The perspective of Science has undergone a radical change with the discovery of the magical dance of the quantum damsels. The Knower  itself seem to be a part of the Knowledge acquired or  to be known. The reality is no longer an objective independent of the experience of the Knower. Each part of the Universe, however small or big part, seem to have multiple existences separated by distances over space.  It is not just three: particle, anti-particle and super symmetry particles but infinite number of existences. The Universe maybe an agglomeration of multiple universes. You and I may be in existence simultaneously in different locations of the Universe.
