“Unease, anxiety, tension, stress, worry – all forms of fear – are caused by too much future and not enough presence. Guilt, regret, resentment, grievances, sadness, bitterness, and all forms of non-forgiveness are caused by too much past and not enough presence.” – Eckhart Tolle
Heisenberg’s Uncertainty Principle and Schrödinger’s Cat
There are two scientific principles that we can investigate further to understand why living from moment to moment or from light particle to light particle – more specifically photon to photon – is so important. The first is Heisenberg’s uncertainty principle and the second is a thought experiment or paradox called Schrödinger’s cat.
Before we open the Pandora’s box of these two scientific experiments, you should know that even MIT scientists are struggling to understand why DNA seems to email it and absorb lights in the form of photons.  some argue that ourselves are nothing more than lights flashing in and out of existence within the quantum field. Our DNA is a communication device by which ourselves interact with this field. Your cells and DNA talk to one another through biophotonic light. 
Keep this in mind, along with repeated platitudes by wise persons for us to live in the moment, as we consider these quantum experiments further.
The Schrödinger’s cat thought experiment was devised by Austrian physicist Erwin Schrödinger in 1935. This hypothetical experiment was designed to point out a flaw in the Copenhagen interpretation of superposition when it’s applied to quantum theory. The Copenhagen interpretation of quantum physics was disrupted by this experiment though it was the prevailing theory of its time.
It proposed that atoms or photons exist in multiple states that correspond with certain possibilities called superposition and that they don’t commit to a specific state i.e. a wave or particle until they are observed.
Though it’s a morbid experiment, it is only a thought experiment. Schrödinger’s cat proves, at least theoretically, that a cat could be both alive and dead at the same time awaiting our observation of matter before it collapses into form. If you aren’t already familiar with this experiment, you can watch this brief video explanation:
The trouble is that we have since learned that nature on the super-microscopic level (quantum level or the level of light particles) is a bit odd. There are all types of speculation about what actually happens in the quantum field or vacuum.
The “empty” space in the quantum vacuum has coherent oscillations that gives rise to mass, form, structure and your very essence as a human being (but also essence to stars, planets, quasars, space dust, etc.)
The most cutting-edge science deems the quantum field as such,
“A universal network of the vacuum harmonic oscillations of the zero-point field can be considered as information exchange in innumerable quantum computational units, or Planck spherical oscillators, where each Planck sphere is one bit of information. It is this unified spacememory network that in-forms and connects all things to produce coherence, order, and systems intelligence.” 
So, while your consciousness is determining if the cat is alive or dead, so is the coherent intelligence of the universe. Therefore, you can’t simply will yourself to be a tree, and turn into one. Yet, you can will your cells to communicate efficiently to be an outstanding, vital, intelligent, and healthy human being, as this is in alignment with Quantum Intelligence.
This also meshes with Heisenberg’s uncertainty principle. It states that you can never know the exact position and speed of an object in space. If we look at the double-slit experiment, we learn that even looking at the position of an object in space can change its speed or even its material form. Everything in the universe behaves like a wave and particle at the same time. This is the true “secret” behind Heisenberg’s uncertainty principle.
What makes a wave (infinite possibility in the quantum vacuum) collapse into a particle (material form as we understand it that looks like a tree, a flower, or a quasar)? The communication of photons or light particles to the field. Moreover, the smaller a particle becomes (on the quantum level) the more it behaves like a wave. 
For us mere mortals, it means that our consciousness is collapsing the field with waves of photonic light encoded with Intelligent blueprints for our form.
A bunch of different waves interacting with the Unified Field eventually collapse via interference patterns into a singular wave.
As we make our consciousness more coherent, the photonic light patterns communicating with our DNA become more coherent as well. You can think of it like taking the noise out of a radio station when you are trying to tune in to listen to your favorite song, or as the ancient Taoists described, letting the sediment settle in a lake so that you have clear water. These are descriptions of living in the moment. Living presently, allows greater presence, which then allows a coherent wave to create the absolute best version of you.
When you live photon to photon – literally one packet of light at a time – you are allowing clear consciousness to direct information, unimpeded, to your cells and DNA.
Alexander Gurwitsch, one of the premier researchers of biophotons, talked about this extensively. Up to one hundred thousand chemical reactions are triggered within your cells in every nanosecond.  
Coherence is a degree of order which is transferred by photons. Coherence is the mechanism activated by consciousness.
When we clear emotional traumas, memories, and outdated habitual thoughts from the mind, our consciousness is elevated and the seemingly miraculous photonic encoding of our DNA can take place. We clear the lake of its sediment, and those hundreds of thousands of chemical reactions in our cells can happen without mishap.
When you start to live in the here and now, one photon at a time, you clear the conscious mind of unnecessary impedance. This is what ancient masters of the mind understood eons ago, and what quantum physicists are uncovering today.
As Jon Kabat-Zinn said, “The only time you ever have in which to learn anything or see anything or feel anything, or express any feeling or emotion, or respond to an event, or grow, or heal, is this moment, because this is the only moment that any of us ever gets. You’re only here now; you’re only alive in this moment.”
