Thank you for your comments, @carton383.
Folks who ponder #TimeTravel are rather compelled to think about splitting or parallel universes. But there are other lines of reasoning for scenarios like Schrödinger's cat or #superposition having to do with limitations in our sensory and cognitive apparatus. The apparent collapse of multiple narratives (timelines) into only one may be a function of how our brain works, and the #Newtonian low-dimensional geometric space that we evolved in. We are simply not engineered to see the other narratives, or rather the bigger picture, which may all be one hyper-complex narrative. It is our reading. Didn't #Schrodinger say that the cat is both dead and alive? Parallelism may be more locally integrated in ways that we can't process, instead of a version A here, and a version B elsewhere. Versions A, B, and others may be all here, but not accessible to us. Just some thoughts.

We'll be posting about #quantum #decoherence in a few days.

So that's my #question to folks who know something about #physics or other relevant #science disciplines:

Have I caused any damage to our existence from pursuing #Newtonian interests that result in a #NonNewtonian byproduct?

Could our universe implode? Might we be tossed into a different dimension? WHAT ARE THE IMPLICATIONS???!?

In my personal pursuit of #Newtonian knowledge about #light, I had accidentally created #NonNewtonian fluid!

The large glass jar that was easy to whisk with #FibreOptic / #FiberOptic bundles was in fact full of a 'solid' from the accumulated #abrasive cleaner particles on the bottom!

Last month me and my grandpa both went after M106 and both images look awesome. Lots of small details can be seen in the bright core of Leonard's image, and a surprising amount of detail can be seen when you crop into my widefield image, even of the smaller, nearby galaxies. This was a fun galaxy to shoot, and many more are coming very soon!

#Physicist Fay Dowker & #science #historian David Kaiser give a brief two-minute explanation contrasting the #Newtonian classical view of Time with the #Einsteinian modern or #relativistic view of Time. Nicely illustrated & articulated, not touching on contemporary #quantum Time.

Right - so 2 basic ways to look at it:

Each specialty branch comes up with their own perspectives, priorities/hierarchies, and jargon. With few exceptions, they stay in their own lanes and do not mix outside their field/subfield. Their writings are stand-alone, rarely intended to connect back to the greater human knowledge base. They'll tell you exactly what "wet" or "sound" is, based entirely on their tiny-desk world-view.

The other way would be a general model of vibration, perhaps based on quantitative info rather than qualitative. It would incorporate all modes of vibratory phenomena, regardless of mediums, velocities, or other characteristics that were fleshed out by some subfield as critical for their particular context & definitions.

Frequency (Hz) actually would be a good quantitative baseline for this, if it hadn't been exorcised from #quantum mechanics.

The "old QM", as espoused by the founders and historic supporters for the split in Physics, used a semi-classical approach that was later abandoned. Later, Pi was added to E = hf as convenience for some aspects, but frequency generally falls away when you work with quantum states ala Schrödinger. #Time is just an input to QM, and is the #Newtonian, absolute kind. The concepts of frequency & wavelength seem to get in the way of the probabilistic formalism.

IMO, the #probabilistic formalism then gets in the way of a #relativistic completion to quantum theory being developed, though in reality, there is no limit to the imaginative supplemental mathematic epicycles that can be added while still spitting out the same expected answers.

My rather standard 6 inch Newtonian telescope produced terrible spikes on bright objects, especially Mars.

I replaced the 3 vane spider (secondary mount) with this curved secondary and it eliminated spikes produced by bright targets.

One consequence of the new approach is that at the human scale, #gravity is entirely #Newtonian. But another is that at galactic scales, the acceleration due to gravity can vary by a small but random amount, as if #spacetime were eliciting some kind of #BrownianMotion on the masses within it - generating the extra #GravitationalForce that holds galaxies together.

Typical discussion in this house (beyond the rack mount circular argument) - #Newtonian vs #Dobsonian.

#BackyardAstronomy is a serious thing.

A friend just sent me the below to discuss the parallels between #Magee and #Rosen in rejecting a #Newtonian theoretical framework for the #social, or for #life (around 13:55). I'm happy to have such friends.

I modified the secondary holder on my 6 inch #Newtonian to have a 180 degree curve, and now it doesn't have spikes around bright stars. Of course, the bigger the telescope, the more difficult that is to do. And if the main mirror is a segmented mirror, forget it and enjoy the spikes.

The dynamical surface density implied by vertical motions (data from Bovy & Rix 2013). The dark blue line is the prediction of the model surface density described above – assuming Newtonian gravity. The light blue line is the naive prediction of MOND.
