My posts about why the speed of light in a vacuum is constant, with no addition or subtraction of source or receiver speed are now burred here. It would be good to consider them alongside argument for the Pre-light binary from experimental evidence. As they support each other. The QM story doesn't address the constant speed of light,

Using the new terminology to describe the physics behind the constant speed of light: ( transmissions is not of seen light moving from place to place in the environment external to the observer but unseen Pre-light-binaries in observation independent reality.
Reason for the constant speed of ‘light’ in a vacuum
The Pre-Light binary(transmitted by electromagnetism) is only an existing/happening thing when it is formed within the environment, being in part a particular environmental disturbance. It is not a transmissible composite without it. Without a transmission means the particle component does not move to the receiver and cause the chemical changes allowing a seen product to be formed. The (as it seems) indivisible particles emitted and associated with seen light are not themselves alone the Pre-light binary necessary for the wave behaviour inferred from interference patterns observed in the outcomes of various experiments. They initiate the pre-light transmission process, and enable detection of it but are not sufficient themselves. The Pre-light binary exists until it is absorbed by a receiving material or object, when it ceases to be existing and happening.
The motion of the source prior to formation of the pre-light binary does not determine the speed of the Pre-light binary (speed of light) when it is in the environment. Likewise the speed of the receiver plays no part in the speed of the Pre-light’ binary after receipt as the Pre-light binary no longer exists. Only the travel in the environment between source material and sink material corresponds to existing of the Pre-light binary. The composition, constituents and concentration, of the environment determines the speed when not in a vacuum. When in a vacuum the speed is constant.
A material object, such as a ball, exists before it is released, and after catching. Taking on the speed of the carrying objects, which will be added or subtracted (depending on same or opposite direction of motion, from the speed of the ball would have if the carriers were stationary relative to the observer.

I added two posts to Quantum physics and the end of reality
,that would be better in this 'conversation', To do with observation product generation, rather than qm specifically . Mentions Elon Musk interview by Lex Fridman no.3, worth a look.

There is a very real difference between absolute and relative measurement. Absolute measurement is one value eg. from x to y, where x and y are fixed starting and ending points. A relative measurement can have different value as x or y is not fixed . making it always necessary to specify the relative context. That is measured from where to where. This is not an original concept it is not a difficult or obscure fact of physics/math. Why are we treating climate change as if global temperature is a singular absolute measurement ? We know the temperature varies and though we may say that the end point ,modern day is a roughly fixed point , the start point of measurement is changeable depending on the choice of the person measuring. That gives a relative measurement. if we choose to measure from the start of industrialization the Earth is still warming after the medieval 'little ice age. co2 rise may be correlated but not causative. It is a limiting factor to plant growth, giving a greener world. Whereas measuring from an estimate of the 'Roman warming' to now shows net cooling. Thank you to Dr. Patrick Moore for some sanity on the issue that is misleading global politicians and the undemocratic WEF. We do not need AI to save us from climate catastrophe. We need to understand the difference between absolute and relative.

Global warming panic is based in confusing of the difference between short term local weather, man made local disaster such arson and mismanagement and long term global climate, ignorance of normal, natural planetary climate fluctuation and the difference between a singular unreal absolute measurement and variable, contextual relative measurement.

What a load of absolute nonsense. See the Greenpeace USA Statement on Patrick Moore https://www.greenpeace.org/usa/news/greenpeace-statement-on-patric/ :
"... Patrick Moore has been a paid spokesman for a variety of polluting industries for more than 30 years, including the timber, mining, chemical and the aquaculture industries. Most of these industries hired Mr. Moore only after becoming the focus of a Greenpeace campaign to improve their environmental performance. Mr. Moore has now worked for polluters for far longer than he ever worked for Greenpeace ... Patrick Moore frequently portrays himself as a founder or co-founder of Greenpeace, and many news outlets have repeated this characterization. Although Mr. Moore played a significant role in Greenpeace Canada for several years, he did not found Greenpeace. ..."

IRRELEVANT TO WHETHER CLIMATE CHANGE MEASUREMENTS ARE ABSOLUTE OR RELATIVE, You supposedly know some math, do you understand the difference? it has nothing to do with an individual's employment.
Georgina Woodward
You are using cancel culture as if disapproval of someone's former employers is evidence that they are incorrect on a specific matter of fact. it is not logical thinking. Climate change depends not just on the variation that has occurred but over what specific period of time. It not only fluctuates but from when, a viewpoint, matters. It affects the value for net change output and whether there has been 9overall cooling or warming found
Georgina Woodward
Patrick Moore has been a paid spokesman for a variety of polluting industries for more than 30 years, including the timber, mining, chemical and the aquaculture industries. On the other hand, climate scientists, who seem to have a majority opinion on the matter of what is happening to the climate, and why it is happening, are NOT paid spokespeople for polluting industries. Why would I bother to do the figures, when I trust climate scientists to do their specialist jobs?
Why don't you stop watching rubbish videos?
Lorraine Ford
Still as irrelevant as last time you tried that failure to use logic. I'm not expecting you to anything with the figures. is it absolute. or relative? The specialists aren't going to tell you by the way. The video gives some context .

I notice from the comments you posted yesterday (see below, where I have highlighted parts of your comment), that you are an anthropogenic climate change denier:

It is well known that carbon dioxide is a greenhouse gas. i accept that some warming may occur due to its increase. However i don't think every bit of bad weather can be accounted for by climate change.
Georgina Woodward
Water more of a greenhouse gas and far more associated with temperature.
Georgina Woodward
The objective truth, is not the fiction predicted by IPCC models. the models are not accurate predictions that fit the incoming data. Name calling doesn't change the facts.
Georgina Woodward
Right now, you seem to think that you are a climate scientist, or better than a climate scientist.
Next, you’ll watch another video and tell us you are a brain surgeon, or better than a brain surgeon.
Lorraine Ford
Confucius said, words to the effect,"' Do not make a mistake into a crime by failure to admit it."
The computers may be very expensive and the models they run very complicated. That does not mean they are actually foretelling the future. The generated fiction rather than objective fact is being used , misleading humanity., Scaring the public, especially children, adversely affecting food production, energy and transportation policies to the detriment of the populous. Costing a fortune but only making things worse for the environment. Horrible lithium mining, non recyclable new' green' technology, people suffering in the cold of winter etc. . co2 encourages plant growth and satellite data shows greening of the Earth is happening.
Cancel culture mentality does not make the failed models suddenly correct or change the data.
Still waiting-relative or absolute?
Georgina Woodward
Unfortunately, Georgina Woodward watched a video, LOTS of crackpot videos, and now she thinks she is a climate scientist, BETTER than a climate scientist.
I'm curious if she also wants to tell the mechanic how to fix her car, or if she wants to tell the dentist how to treat her teeth, or if she feels compelled to tell the nurses and doctors how to treat her medical conditions.
Lorraine Ford
Here is some expert testimony by a climate scientist. Knows about the subject. Unlike Lorraine who believes in the media and political sensationalism and fearmongering. Belittling interest in the actual science and real world happening.
