You Are Here - 9

Fig. 1 Special Spatial Considerations
(space parts is space parts?)

The saying "Parts is Parts" is not just for Wendy's anymore:

"Imagine: You and your sister are 66-year-old twins on Medicare who share the same family history of Alzheimer’s disease, making an early diagnosis critical for long-term planning and preventive health care. Since Medicare provides coverage for a cognitive screening as part of each year’s wellness visit, you believe that diagnosis, if needed, will occur.

Let’s say you live in Hartford, Connecticut. Your sister is some 26 miles away in Springfield, Massachusetts — so close that you often share Sunday dinners. Yet according to a new study, you are 18% more likely to obtain a diagnosis of dementia in Hartford than your sister in Springfield. 

How could this be? According to Medicare data, the health care system in Connecticut may be doing a better job than Massachusetts of screening and diagnosing Alzheimer’s disease or related dementias and referring patients to specialists, said lead study author Julie Bynum, a professor of internal medicine and geriatric and palliative medicine at the University of Michigan Medical School in Ann Arbor.

Such disparities happen across the United States, Bynum said. In fact, depending on your ZIP code, you may be twice as likely to be diagnosed in some areas of the country as others"

(Depending On Your zip code). Not only that, in this equation the problem could even be Divided By Age).

The "not enough doctors" combined with the "different schools, different textbooks, "different diagnoses" problems are not just for medical doctors anymore.

It's the same in physics in that there are no doctors in our current space and time location who can diagnose the gravity of the problem of our scientific cognition concerning quantum-gravity: 

"Most physicists expect that when we zoomin on the fabric of reality, the unintuitive weirdness of quantum mechanics persists down to the very smallest scales. But in those settings, quantum mechanics collides with classical gravity in a resolutely incompatible way. 

So for almost a century, theorists have tried to create a unified theory by quantizing gravity, or sculpting it according to the rules of quantum mechanics. They still haven’t succeeded."

(Quanta Magazine, emphasis added). That article is not the only diagnosis going on:

"In a classical universe, if we knew all the positions and velocities for all particles, we could predict the future and the past. Quantum mechanics is not like this. It shows that reality is not deterministic but is probabilistic. The precise location of a particle cannot be predicted in advance, even in principle. This is the most accurate theory we have. It can account for all the forces of nature, except gravity. Why is gravity so different? Why can’t gravity be modeled by quantum mechanics? Why is Quantum Gravity so difficult?

General Relativity is very accurate, so why must we quantize gravity? Because quantum mechanics works. And General relativity falls apart at quantum scales.

Quantum mechanics says that particles are not like little cannon balls but are like a wave described by a wave function. Particles are waves until some kind of interaction occurs, at which point the wave becomes localized like a particle. But prior to this, we can't predict the location of the particle.

But a photon or electron, just like any quantum particle must also have a gravitational effect because that's what General Relativity says. But if it's a wave prior to an interaction, and it could be anywhere until the moment we measure it, where is its gravitational effect located? General Relativity can't tell us where. We don’t know how this works because we don’t have a quantum description of gravity."

(From the video below). I guess we don't know everything about 'here' no matter where we seem to be (You Are Here, 2, 3, 4, 5, 6, 7, 8).

Especially in the 'political spaces' of Earth One.
