Time and relativity (split from The Nature of Time)
No that's not what I'm stating I simply stated in order to measure something you require space. I did not state change requires measurement how would you ? you would have an effective range of interaction between the two particles ? The better question would be is how you can even have a particle without space for it to reside ? the point like characteristic however miniscule still resides in space.

Time and relativity (split from The Nature of Time)
You also require a space to measure A definition I always apply to physical is any measurable property, quantity or state. edit I should add the caveat that a common QFT view is that measurable equates to real as per real vs virtual particles. Though its better described as field perturbations vs excitations.

Time and relativity (split from The Nature of Time)
well any waveform changes so obviously you need time. You must have a space to take any measurement or to simply have some quantity to change of what it is to change. If you have absolutely nothing that changes then you certainly cannot apply time. You can simply state time exists for anything that has change.

Time and relativity (split from The Nature of Time)
All particles have a range of field influence, Such as the Compton wavelength, harmonic oscillations etc. the point like characteristic is only one characteristic that defines a particle the wavelike characteristics do apply. \[E_{kinetic}\propto T \] the kinetic energy of the particle is proportional to its temperature contribution so it must have space to move correct me if I'm wrong lol how so ?

Black Holes are Paradoxical!
I like your approach into the basis of relativity +1

Black Holes are Paradoxical!
nope not really mind science has very little to do with physics. In particular it certainly doesn't validate some godly observer view point. We don't count spiritual astral projection like states in physics. Now do we count other mental like powers as being involved

Time and relativity (split from The Nature of Time)
without gravity certainly however you can't really have something that changes if that something has no spatial dimension. Can any object or state exist without a spatial dimension of some form. Time isn't an entity unto itself, so under that in order to have time you must something that changes

Electron black hole?
\[e^-+e^-\overbrace{\rightarrow }^{photon} e^-+e^-\] There is the Moeller scattering of two electrons fired at generating a scattering event of two electons. You will subsequently generate an off shell mediator photon. So you will be generating light, however assuming that you can generate sufficient mass density to have the mass below the Schwartzchild radius the photons would not escape. See Swansont's reply above However electrons will repel each other so simply firing them into a specific region will not be sufficient. I don't think a magnetic trap will suffice either as the EM field interactions will cause further scatterings and particle generation/ annihilation events. However lets assume you can generate a BH by some method of containment. The Hawking radiation will be fastest the smaller the BH. So the initial BH will want to decay extremely quickly however Hawking radiation only applies when the Blackbody temperature of the BH is higher than the Blackbody of the surrounding region... Not sure how that would work as your firing beams into the confined space.

Time and relativity (split from The Nature of Time)
As time is a property that describes rate of change you must have the requirement of some state, object, field, space (as volume) that changes. as long as you can measure something then time is applicable. Obviously measurement isn't a requirement for time to be involved either as things change even without being measured. However you must have something that changes even if that something is another property.

EPR & SR
One thing I've always found annoying about how entanglement is described in numerous papers involving the various paradoxes and interpretations is that very few of the papers ever mention that the entangled particle pair had a causal past connection at the moment of entanglement. That causal connection also prepares the allowable states in accordance to the conservation laws. (charge,energy-momentum, flavor, color, isospin, lepton number ) etc. So lets examine that using the parametric down conversion of a monochrome light beam through the beam splitter common to the EPR experiment. As photons are used were dealing with polarity states (left and right circular polarity states). Ok so we don't know the which particle is which so naturally we have a superposition probability state that will be common to both wavefunctions as its fired to the detectors. (treat as one state shared by both) or treat as two identical states. (seems to me shouldn't matter which descriptive is used in this case. The probability is further increased by the detector alignment at detector A and B in so far as the angle is concerned. That gets factored into the correlation function. Now lets stop for a second and think about this. The state sent to each detector is a probability state. It is not the physical state. We do not know the physical state so we can only describe the probability state. Once you observe/measure (in QM measure is identical to observe), you have determined the physical state so naturally the probability state is no longer required. Applying the previous conservation laws the person at detector A will automatically know wheat state should be detected at detector B as being the opposite polarity. There is no cause or communication needed beyond the original preparedness of the entangled particle pair. The very act of generating an entangled particle pair in the first place requires a causal connection. (the two particles must interact in order to become entangled). the particles themselves do not communicate between each other nor change states as a result of the superposition wavefunction collapse. The communication that occurs is when you go to communicate the results of one detector to the other detector or for timing purposes. if for example observer at detector A does their measurement. detector B doesn't know the results until detector A informs them. Until detector B gets the results that detector will still treat the state as a superposition state. A probability state isn't a physical measured state. Any measured stated is a determined state. A key note you can have a superposition of waveforms that are physical (ie a collective of different frequencies in the same space) thats a bit different than the entangled superposition state which is a probability function.

Super sensitive single string hypothesis and extended periodic table
I don't see how you would get a string loop to represent charge.... In string theory itself charge is represented by where the endpoints lie on the graph/ brane. However string theory doesn't apply a single string either. Quite frankly having a single string represent all of the periodic table would be an impossibility.

Time and relativity (split from The Nature of Time)
We have tested the weak equivalence principle on the moon and found it holds as \[m_i=m_g\] held on the moon test it follows that the time dilation aspects of GR will also hold

What is the speed of electric current?
on that I fully agree with you, I enjoy a good scientific discussion its natural and part of the scientific process to examine different view points for validity etc. A good discussion should include alternate views for examination
-
What is the speed of electric current?
I got rid of that neg rep you got above you didn't deserve it there even though rep is a trivial thing
-
What is the speed of electric current?
ok no offense taken and I had no intention of giving offense so My apologies on that by the way I dont feel you deserve that neg rep point so I'm going to remove it.
-
What is the speed of electric current?
my apologies but did you not correct how I verbally described the above ?
-
What is the speed of electric current?
Sure we can focus if you like on language. Either way the flow of charge is a useful descriptive and it is part of the high school curriculum
-
What is the speed of electric current?
charge isn't carried by only electrons with flow of charge you are describing the effective average of each individual atom in a conductor. The photons are the mediator of charge in interparticle interactions. In this case specifically atom to atom. This is effectively the same as your EM field descriptive. With flow of charge you are not specifying the flow of a specific particle but the flow of the effective charge at a given locale
-
What is the speed of electric current?
I'm prepared to hear your argument why do you feel the flow of charge doesn't have a rate of c ?
-
What is the speed of electric current?
yes you are correct I specified for of charge as that's the lanquage used in a lot of high school lessons. A lot of the high school physics textbooks also apply the flow of charge terminology and subsequently some of their exam questions will trip a student up if they don't realize the question applies flow of charge vs flow of electrons. ( there is one specific lightning question on flow direction for a specific charge that students will get wrong if they don't pay attention to the flow of charge specifically). lol at least in Canada flow of charge in high school is still taught today, as I often help volunteer as an assistant instructor to high school and undergraduate students

Question of three clocks
I agree the earth spins slowly enough that it wouldn't make any significant differences. For the first part if your applying the line elements already derived such as he Schwartzchild metric etc the coordinates vs proper time are already incorporated. You still have to be aware that those same line elements will return the proper time. Same goes for expressions for proper time already accounting for coordinate time The commonly used proper time to coordinate time expression is as follows \[\Delta \tau =\int \sqrt{1- \frac{1}{c^2} \left ( \left (\frac{dx}{dt}\right)^2+ \left(\frac{dy}{dt}\right)^2+ \left (\frac{dz}{dt}\right)^2\right )}dt\] which works fine until you have other factors such as frame dragging, rotation or acceleration. For rotation as above \[d\tau=\sqrt{1-\frac{\omega^2 r^2}{c^2}}dt\]
-
What is the speed of electric current?
as the others mentioned there is a distinction between flow of electrons and flow of charge. As you noticed flow of electrons is extremely slow however flow of charge is near c.

Is "Galilean gravity" a thing?
The history of Eather theory is quite interesting. I have a copy of a 1918 physics textbook that described it. It didn't include anything involving relativity and the entire particle model only comprised of protons and electrons. Neutrons were discovered roughly 1935 if I recall.

Why is a fine-tuned universe a problem?
Your work sheet looks good I don't see any problems or mistakes in that analysis well done.

Question of three clocks
It simply means there is always something new to learn and if your dedicated in your studies you never stop trying to learn new aspects of a given theory. from a preliminary quick research it seems to me applying the Carter Constant for the elliptical orbit may give me a methodology. I wonder if Markus or Jadus agrees with that approach https://en.wikipedia.org/wiki/Carter_constant there we go I think I have an applicable method https://en.wikipedia.org/wiki/Boyer–Lindquist_coordinates#Spin_connection edit speaking of challenges I wonder at the steps to get get proper time for an observer at infinity to a clock orbiting Earth with the subsequent transverse blue/redshifts.
