All-Knowing from the Physics of Light


“Can one discover the mystery of God? Can one discover the limit of the Almighty?” Job 11:7

Our focus (in this ongoing series of articles on light) now shifts to the omniscience of God. “He is the knower, the thing that is known and the knowledge, all One.”

“The Holy One, ‎blessed be He, recognizes His own truth (his true existence) and knows it as it is. He does not know it with a knowledge that is outside of Him like we know (things). We and our ‎knowledge are not one, but the Creator, blessed be He, and His knowledge and His life are ‎one from every side and every angle and in every manner of oneness. If He lives with life and ‎knows with knowledge that is outside of Himself, there would be multiple Gods – Him, His ‎life, and His knowledge. And this is not so; rather, it is one from every side and every angle ‎and every manner of oneness. It emerges that He is the Knower, He is the known, and He is the knowledge itself; all is one. And concerning this matter, there is no way of describing it in words, nor is it within the mind’s capacity to understand it fully…’      (Maimonides Laws of ‎Foundations of the Torah 2:10). ‎

God being omniscient means having complete and total knowledge of everything past, present, and future. This includes knowledge of all events, thoughts, actions, and outcomes and the inner workings of every heart and mind. God’s knowledge is considered exhaustive, perfect, and timeless, encompassing all things that exist or will exist. God’s knowledge is infinite, encompassing everything in this universe and more, all together at the same point.

When you find out that light has the inherent capacity to transmit an infinite amount of information on a single light beam, you will probably not be overly surprised by this information. In theory, quantum entanglement and quantum teleportation suggest that an infinite amount of information can be encoded onto a single photon (light particle).

Professor at the University of Vienna and director of the Institute for Quantum Optics and Quantum Information, Mario Krenn, made the following assertion:

“Light’s orbital angular momentum, or OAM, is theoretically unbounded. This means that, in theory, one has access to an unlimited number of distinct states in which light can be encoded.”

The goal of physicists has been to find a way to encode more information into photons. In the 1990s, they started looking into twisting light, which can be transmitted like a corkscrew over long distances. This phenomenon, referred to as orbital angular momentum, or OAM, paves the way for incredibly quick and completely secure communication.

In theory, each photon, which is a particle of light, is capable of being bent in an infinite variety of different ways, and each bend has the potential to carry a unique bit of information. This demonstrates that, by utilizing OAM, it is possible to transfer an infinite quantity of data at precisely the same time over a significant distance.

This is analogous to what occurs now with the various colors of light, also known as frequencies, inside optical fibers.

All this indicates that the physics of light makes it possible to encode infinite information onto a single beam of light using just one light source. This information would be transmitted at the speed of light in a manner that is virtually identical to instantaneous transmission. There is no other physical medium in which this is even theoretically conceivable. Because there is no way for modern scientific research to verify such a hypothesis, this can only be considered a theory.

Scientists cannot store or send an infinite amount of information because they do not have that capability. Current technology can’t approach this limit due to noise and errors in transmission and detection. However, this is possible, according to the physics of light, if it were ever put into practice. It is theoretically possible for a single light beam to transmit an infinite number of conversations simultaneously.

By taking advantage of the properties of light, the transmission of large amounts of data in a short amount of time can be accomplished using fiber optic cables. The technology that is in use today only makes use of an infinitesimally small portion of the data-handling capacity of light, and even this infinitesimally small use of the data-handling capacity of light is mind-boggling. The limitations of our technology, not the constraints of light, prevent us from accessing the infinite data-handling power and capacity of light. Light itself poses no such restrictions.

In addition, because light possesses this property, two people can have a conversation that is entirely private or even a secret. In encrypting quantum communications, the orbital angular momentum, also known as OAM, of light photons can be utilized. In this method of communication, a “key” to an encrypted message is created by stringing together a series of spinning photons (photons are “particles” of light).

This key, known only by two people at a time and shared between them, protects the data sent over the link. Any attempt by an eavesdropper to intercept the key will be fruitless due to the laws of quantum physics and the properties of light, so there’s no point in even trying. Any attempt to measure the key will result in the key being lost forever. This form of quantum communication carried out over light cannot be intercepted.

Therefore, a single light beam can deliver infinite information to which only the person or persons who possess the key have access.

We know that God’s knowledge and comprehension are unlimited (omniscient). Furthermore, we are aware that no human being can fathom what goes on in the mind of God.  If light, a mere physical creation of God, has infinite potential, it is wise and safe to believe and know that God’s mind is unfathomable. We must trust all that God does is wise and merciful.
