Any Physicists Here?

I got that impression because Hubble's "horror" statement is commonly taken out of context to cast doubts on science, in order to pave the way for a creationist argument.

Ignoring things you don't like and choosing the ones you do isn't science. I understand though, we all have our reasons. There are valid theories not accepted because of being presented by an unqualified person.

As far as casting doubts, much of the physics theories have done that to themselves. Alot seems to be right but the same scientist know somethings don't add up, or huge chunk(s) of information is missing.

We manipulate matter consciously and subconsciously, continually from the time of conception until we are no longer part of this system. Right or wrong, is it really so hard to imagine a much bigger version of the same exists?

I have a theory about dark matter:

The double-slit experiment says that elementary particles can behave as both particles and waves. I've never been able to fully accept that. It means that a particle turns into a wave and then recombines to become a particle.

However... what if dark matter was a fluid that permeated the universe. All particles vibrate due to their energy. If you drop a rock into a pond it creates waves. In the same way if you shoot a particle into a fluid it will create waves.

So the particle is moving from the emitter towards the slits. There's a wave in front of it. The wavefront bounces off the solid area and also goes through the slits. This creates an interference pattern. The interference pattern is a complex wave with high and low pressure zones. The particle will follow the path of least resistance. Sometimes it will strike the plate. Sometimes it will go through the left slit and sometimes through the right.

So, yes, there's still wave-particle duality but it's because there's a wave around the particle. The particle is always a single particle and is never in two places at the same time. It's wavefront, however, is affected by the surrounding and dictates the path the particle will take. The path is randomized due to various factors so sometimes the path of least resistance is the left slit and sometimes it's the right slit. The wavefront behind the slits has all sort of peaks and nulls due to interference and the particle follows the troughs.

Therefore what I'm thinking is that wave-particle duality is actually due to a dark matter fluid that creates waves around particles.

It also explains the patterns with a single slit. The wavefront passes through the slit and there is diffraction off the edges of the slit. This causes lobing of the wavefront. Sometimes the particle will follow a sidelobe path due to random fluctuations.

IOW, there's a wave that propagates through the fluid and the particle follows the troughs in the wave.

I think you're talking about "pilot wave " theory.
I'm a Copenhagen guy....
 
The idea of there being some fundamental property of the universe that we haven't yet identified seems entirely probable to me, almost certain, but dark matter is theorized due to effects we've observed on the behavior of galaxies and anomalies we've found in the rate and behavior in how the universe seems to be expanding. In other words, dark matter, assuming it exists, has mass. If the fluid you propose was dark matter, we could detect it. But the idea of something massless and all-pervading having the effects you suggest has serious proponents in the physics community who suggest an updated version of aether theory.

Perhaps our difficulties with aligning observations of quantum reality versus everyday reality and astrophysics reality is that we are 2 bit computers trying to perceive a 1,024 bit reality. We just don't have the hardware or capacity to see the whole picture. For a fish, the flight of a bird is truly otherworldly and beyond their ability to process even though it does exist.

Just cause we can't figure it all out now doesn't mean we can't learn more over time.
No one had a clue about the quantum until the last few hundreds of years. Now we have a very good understanding of it.

Here's one for you. 1-dimensional space and 3-dimensional time.

Well, obviously!

I did scan the whole paper. Playing with math is fun and keeps theoretical physicists employed. Whether it has anything to do with (observable) reality is an entirely different question. But we never know what theory might hit on something. The problem (or benefit?) is there is 1000:1 or 1,000,000:1 ratio of hypotheses to confirmable theories.

The smallest inert particles that exist are swimming in an ocean of energy. Energy and particles that are beyond our means to detect for now. The reality we know is the waves from those vibrating particles. Shape, size, clusters, proximity of these particles could create very different interactions. Waves that reinforce, amplify, compound, cancel, collide, combine, absorb, repel and interact in many ways (the physics behind your guitar producing sound coarse representation of this), yet really not so many variations with what we know about the universe.
The particles and waves are not the fascinating part. It's a field that exists outside (and inside) of all time and space. Remains stable at least for what human consciousness has observed and forges our universe with an intelligence and consistency we don't comprehend. What if the energy field ramps up down or pauses and time/reality exists in many forms, and we can only see/interact with a small part? Would the interaction we have affect/influence the levels we don't see? Could our consciousness be tuned to a narrow band in a much, much wider spectrum? Or take samples of that information at intervals that leave much of it hidden from us? What if the "movie" were recorded at a trillion, trillion frames per second and we could view that at one frame per second slow motion, or speed it up trillions of times in high speed and see it and all variations simultaneously? As humans maybe we only see one version? Maybe we see all and filter out all but one?
Fascinating things to think about but we lack the tools to prove. Maybe someday, maybe not? If someone ever attained to ability to manipulate some of those higher-level states, we may start to see some crazy things... UFOs? Time travel? Teleportation? Particle/reality gardening? :)

Nah it's an "artist rendering" video (probably AI will be doing these soon). Even the "images" on NASA are artist interpretations. There is no way to image directly something 300 million LY away (Edit: with detailed resolution as depicted in the images/video).

As a scientist this marketing stuff ("artist fakes") pisses me off.

Agree but it is an interesting rendering, all things considered. The JWST is a vast improvement over image captures via Hubble. All those millions of galaxies really puts our existence into perspective. Especially awesome is the lensing effect gravity has over light, which is now observable.

Yeah, and if this was real how long would it take for this to happen as illustrated above?
 
In 1921, Albert Einstein was awarded the Nobel Prize in physics for his theoretical theories and his discovery of the law of the “photoelectric effect.” In 1905, Einstein considered that light has a nature of both a wave and a particle. This lead to the development of “photons,” or photo electrons, which gave light a wave-particle duality.

Now it must be noted that Nikola Tesla wasn’t just a theoretical physicist like Einstein, but was an experimental physicist as well. In 1896, Nikola Tesla was the first to propose that radiation had both particle-like and wavelike properties in his experiments with X-rays. In experiments with his newly developed high-vacuum tubes and his high-frequency disruptive coil (Tesla Coil), Tesla shot cathode, and other rays at different metals noting the differences in reflection the streams made upon the metals. Nikola Tesla preceded Einstein by 4 years on the law of the photoelectric effect publishing a patent titled “Apparatus of the Utilization of Radiant Energy.” filed in 1901.

Tesla still recieved no Nobel Prize.
