The problem with this idea is that light has a duality of acting like a particle and a wave. You might think that you can separate these properties, but nothing could be further from the truth. So, though photons exist, they are also waves too....all the time. If you separate this in your mind, it will give you contradictory results in your experiment. That is why the math is so very important.

I have no problems with particle-wave duality. I am more interested in nature of information and it's relationship in the experiment. It is more like I will try to draw a diagram using test result as way to connect things relationship wise (in reality I have done this already somewhat, in my head) and to pull ideas from those diagrams to test further. Reason why I am not taking courses in quantum mechanics and particle physics is that, shooting laser is easier, cheaper and cooler (I want being mad scientist to be my hobby)
Anyway, I'll try to explain how I try to approch this after I have slept some.

Look I'm interested in QM as well, and although I do understand some mathematics, I don't have the mathematical ability to understand the equations. A lot of what I theorise is visual and I use what mathematical skill I have to make sense of it afterwards. But I get what Paul is saying. You can't rule out the maths unfortuantely. Some of QM only makes sense with maths. Trying to visualise certain aspects is only possible with deep understanding usually gained by those who have done the groundwork. I accept that I will never have that ability myself to put together something like the schrodinger equation. But I did find a correlation with that of the planck units and the universal wave equation using what maths ability I have quite interestingly. Is it possible that the whole universe is just light? And that a extremely high energy gamma photons are the heart of the quest for 'quanta'? Anyway, welcome to the forum.

I think it is far more likely that the universe is a "bunch" of waves that permeate all of space/time. Matter and gravity and everything else we see as matter or energy is manifested in these waves. I think that string theory is all but a thing of the past now. I still study QED, but it is, as always, a difficult slog with equations that at times, barely make sense to me. And I do have an extensive math background.

Well the heart of everything is energy and waves as we now know. I like studying things like extra dimensions and multiverse theory. I just get this feeling that the photon is at the very centre of all phenomena. I'll share with you a very basic coincidence I found and a couple of ideas.




This shows that c/(1/tp) = c/f and that when the wavelength is worked out it matches the planck length (lp)
tp = planck time
The only reason why it doesn't equal exactly is due to the error in the constants.

You can then go on to calculating the photonic energy of each photon. At this sort of scale we are talking about photons with an energy of 12.29GJ [76.71 BeV] (Bronto-)

I also believe in the universe being made up of quanta like this at planck length scale:



Only rather than them being classical particles, they are wavefunctions that can take on wave/particle properties just like photons.

We also know through pair production that matter and light is interchangeable.

And finally a snapshot of a excel document I have working out how many of these 'quanta' theoretically could exist in a 1m^3/s of 4D spacetime.



The numbers get pretty crazy. Especially when you start working out the different possibilities there are based on 2 states.

You don't have to agree, but its just an idea i've been pondering about and thought I'd share.
