Physiology & Medicine / Re: Why do even non-believers pray or appeal to God in times of need?

Before trying to explain why something is true, it's a good idea to check if it is true.

How often does the cockpit voice recorder tell us that someone's last words were"Our father who..."?

I spent some time working with a forensic phonetician. He assured me that the last word on every CVR he had analysed (several dozen) was always "sh1t". It is a remarkable finding: his skills ranged over at least ten major languages, but whatever the native language of the pilot, years of training kick in at the last moment; "in an emergency, speak English".

The only exceptions I know of, were the 9/11 hijackers who attempted to contact some deity before killing 3000 innocent civilians. However they don't count as they were not in time of need.

New Theories / Re: What is a photon ?

« on: 13/07/2020 17:04:58 »

What physical experiment could be performed to demonstrate that particles are Riemann spheres?

Orientate an Electron such that it's axis (pointing from the point 0 to the point ∞) points in the "up" direction. Then it will not emit a photon in the "down" direction.

Also: particles seen from their northern hemispheres will look different as seen from their southern hemispheres.

Wrong. The direction of photon emission when an electron drops from excited state to ground state is random with respect to the electron's spin state, which is the only way of talking about an electron’s axis.  The direction of photon emission is determined in a probabilistic manner by multiple factors including the prevailing magnetic field, of which the nearby nucleus is a major component, and preserving energy momentum conservation over event accumulation.

In addition, electron spin is a matter of angular momentum, in effect spinning clockwise or counterclockwise. It is not a matter of which way a pole is pointing. Electrons with opposing spin values are not ‘upside down’ with respect to each other. They are spinning in opposite directions. To drive that home, the only formulation for spin states that matches measurements is the formalism of angular momentum.  For that to be the case, the clockwise or counterclockwise spin must be with respect to a fixed axis. That is, your hypothetical 0 and ∞ axis must always point in the same direction, negating your argument.

Now explain what differences there may be between the two hemispheres of an electron. Oceans, continents, ice caps? Your insistence that the metrics of a Riemann sphere are those of an ordinary sphere and not the varying metrics of a complex plane mapping argues against any difference.

Also, since the question Kryptid asked is about a physical experiment, how would you determine which photon came from which electron and how to determine the axis orientation of the individual electrons?

So what does “communicated between fields (plural)” mean?

Think of the Feynman diagram of an electron scattering off an electron. What happens is: one electron must tell the electromagnetic field that it wants to scatter of another electron following a path λ, and it must specify its momentum. This must be read off the electron field interacting with spacetime. Then the electron must specify it's expected momentum change. Then the electromagnetic field must compute the virtual photon direction and wavelength and the positions for invoking the creation and annihilation operators, then the virtual photon must communicate the change of direction of momentum to the other electron. Only then can the virtual photon be emitted.

Wow, where do I start?

To begin with, you are using two different meanings of the term ‘field’. Originally you used the term with respect to a particle being a ‘vibration’ in a field, which would imply field theory, a field being a mathematical apparatus for determining the properties at any given point. Now you are using the term to refer to the electromagnetic fields of electrons. Same word, different meanings.

The term λ (lambda) does not appear in Feynman diagrams. That term is used in General Relativity for the Cosmological Constant. What does appear in Feynman diagrams is the term γ (gamma), which is the symbol for the photon. In Feynman diagrams, it is the label applied to the wavy line that indicates the exchange of virtual photons. This diagram show electron-electron scattering.



In Quantum ElectroDynamics (QED) for which Feynman diagrams were first invented, the path is not first chosen. In theory, any path at all might be used, each having its own probability amplitude. This is a wavelike entity. As such, probability amplitudes constructively and destructively interfere with each other. The effective path is the one with the greatest surviving probability amplitude, and usually the only survivor with a resulting probability (square modulus of amplitude) of unity. Paths happen. They are not chosen. There are experiments demonstrating multiple paths being used such as the famous double-slit example.


There are people here who are familiar with deep Physics and deep Mathematics. You cannot make it up as you go along and not get called out.

Chemistry / Re: Why don't electrons crash into the nucleus?

« on: 02/06/2020 15:52:35 »

It is entirely reasonable to say that an electron in an atomic orbital *has* fallen all the way to the central nucleus. It just so happens that electrons are effectively fluffy, and spread out over a volume 100,000 times larger that that occupied by the nucleus. Similar to how the atmosphere on Earth has fallen all the way down to the ground, but still measurably extends more than 100 km from the surface.

Physics, Astronomy & Cosmology / Re: Is the speed of light constant?

« on: 29/05/2020 23:52:05 »

Is there a simpler explanation?

Probably the simplest equation to calculate the speed of light in a vacuum:
c = 1/√(ε₀μ₀)
where:
- c: velocity of light in a vacuum
- ε₀: permittivity of a vacuum
- μ₀: permeability of a vacuum
Look at just the last 2 lines of this section: https://en.wikipedia.org/wiki/Electromagnetic_wave_equation#The_origin_of_the_electromagnetic_wave_equation

This is just as simple as the equation for the speed of a vibration on a string (eg a guitar string):
v = √(T/ρ)
where:
- v: velocity of a wave in the string
- T: tension of the string
- ρ: density of the string
Look at just the last 3 lines of this section: https://en.wikipedia.org/wiki/String_vibration#Derivation

COVID-19 / Re: How is it possible for a test to get it wrong 75% of the time?

« on: 07/04/2020 08:11:42 »

covid-19 usually infect the lining of the throat first, so testing a proper throat swap would detect the virus pending on the sensitivity of the test.
What if a whiff of viruses went straight into the lungs through deep breathing?  Then the virus is difficult to detect early on, and these are usually diagnosed through a CT scan (3D sectional photos of the lungs).
The precence of the virus in blood is a clear indicator of infection, but the blood does not get infected early on.
The virus may also be present in the faeces.
Even asymtomatic patients can transmit the virus.
So basically, no single simple test can reliably detect an infection early on to ascertain who is not infected.

Therefore, social distancing needs to be maintained to avoid infection.

COVID-19 / Re: Why is the coronavirus fatality rate in Germany so low?

« on: 21/03/2020 12:26:49 »

This is most likely to be a statistical artefact of the testing.

The Germans have tested a lot of healthier people, including a lot of people from ski resorts.

Fitter, younger people tend to go skiing; older people in poor health do not (they board the Diamond Princess). So although the detection rate is high, the risk of severe disease is low, giving the impression that Germany is somehow special.

New Theories / Re: What is the relationahip between mass and charge?

« on: 28/02/2020 21:20:39 »

GG: A photon from the right and a photon from the left of spaceship will have exactly the same energy to a stationary spaceship. Yet the effect of the photon to the spaceship moving toward the photon will be at a higher energy level due to the speed of the spaceship. The spaceship is filled with photonic dot-waves and these will add to the photon  as it hits the spaceship or subtract from the photon when the space ship is traveling in the opposite direction.

Okay, perhaps that's fair. Your model is still incorrect because it predicts the wrong value for known constants. You claim that those constants can vary in strong gravitational fields, but that isn't correct. You don't even need relativity to demonstrate that. Conservation of energy in itself is enough to demonstrate that the gravitational constant does not change in high fields of gravity.

Consider Pluto as it is right now. It has a set gravitational potential energy that is determined by the Sun's mass, its own mass, its distance from the Sun and the gravitational constant. Change any one of those parameters and the potential energy changes as well. Now we collapse the Sun down into a black hole of equal mass. The Sun's mass, Pluto's mass and the distance all remain the same. But what if we assume that the high gravity of the black hole increases the gravitational constant? That would result in more force per unit mass, which would increase the gravitational pull on Pluto. This results in a higher gravitational potential energy.

This, however, cannot happen. More energy cannot spring up spontaneously out of nowhere. That violates conservation of energy. This is how we know that the gravitational constant does not change from one scenario to another.
