Light as a wave or particle (split from A rational explanation for the dual slit experiment)
You need to discuss this matter showing good faith: addressing the comments made to you and not "forgetting" past exchanges. Examples have been given to you, so let's not pretend that this has not come up before. It's not as much what you're missing as what you're conveniently ignoring. So let's not ignore things anymore. You even admitted that light delivers its energy in a localized fashion, which is a particle behavior and not a wave behavior. https://www.scienceforums.net/topic/125968-delayed-choice-experiment-split-from-question-does-the-double-slit-experiment-prove-free-will/page/2/?tab=comments#comment-1189287 So I will reiterate my previous example: if light were a wave it would be able to share its energy among multiple atoms when interacting, because that's a wave property, as is losing just part of its energy. But it doesn't do that. The example I used was a 2 eV photon and a bunch of atoms with a transition at 1 eV. We don't see the photon getting absorbed - no partial loss of energy, and it doesn't cause excitations in two atoms. If you insist that light is a wave, all the time, and never shows particle behavior, how do you explain that it doesn't show wave behavior, and shows particle behavior in these instances? (and please note that "I'm not convinced" is not an explanation). You have proposed a model here, and you need to support it.

Size of an event in Spacetime
If it’s meters the time will not be milliseconds. c = 3 x 10^8 m/s. meters means nanoseconds. This issue is as I had mentioned. When I did my postdoc at TRIUMF, the cables were labeled in nanoseconds, so you could account for the signal delay time from different detectors. It’s not that you are worrying over nothing, it’s that you’re not pointing out something that others have missed, and you are framing it as such.

Size of an event in Spacetime
I find no matches to a member with than username. The only hits on that are in this thread. I will ask again: Under what circumstances will this matter? Alternately, give a pointer to an experiment where this would matter where it was not taken into account. I am familiar with experiments which use coincidence detection, so I know of experiments where this is explicitly taken into consideration, because circumstances dictate that.

Light absorption and linewidth (split from A rational explanation for the dual slit experiment)
Which has nothing to do with the topic of discussion The "leaps" being discussed are ones of energy and not location, so this isn't really applicable.

Light absorption and linewidth (split from A rational explanation for the dual slit experiment)
Natural linewidth is not considered broadening, in my experience, as it is inherent to the transition. It's the starting point, and the other mechanisms give you broadening. Which is why efforts are made to reduce the other effects, such as doing Doppler-free spectroscopy to reduce/eliminate that source of broadening.

Universe is (In)Finite?
! Moderator Note The issue wasn't units (and your argument here is flawed), the issue was your observation that "we should be thinking about the progression of physics *between us and infinity*" and that you have shed no light on that progression (whatever "progression" means in this context) ! Moderator Note Repeating the phrase "manifestations of the Singularity" is not a substitute for a testable model, not does it explain anything about this progression you mentioned. If all you have is hand-waving, I will close the thread. Do you have anything of scientific substance to offer?

Speculation
This is why we put error bars on results. In science we tend to quantify the uncertainty in results. 1) You haven't, and 2) You don't get to make that assessment. (the two are not completely independent)

Why is the time axis in a space-time diagram a distance
You can pick whatever values are suitable. You can pop on whatever exponent of 10 is appropriate, like light-seconds (x10^-6) if your distances are in km But you need the factor of c so that you have consistent units, when doing things like constructing a spacetime interval.

Size of an event in Spacetime
Who is CollinJ and why is this relevant? Under what circumstances will this matter? If I am driving my car and say that I will arrive at some time T, does it matter that the front of my car arrives a fraction of a second earlier? No measurement has infinite precision.

Light absorption and linewidth (split from A rational explanation for the dual slit experiment)
Lifetime, as I said, but that also means you can't tell exactly when the transition took place.

Light absorption and linewidth (split from A rational explanation for the dual slit experiment)
"Reference frame of light" make no sense from a physics perspective; this is an issue of relativity and light does not have an inertial frame. We observe that when you send a photons at atoms they can be absorbed, and the atoms emits light some time later. This observation takes place in the lab frame, not the photons. The physics used to describe this is also based in the lab frame. We don't have physics that can be used in a photon's frame, because there is no transform that gets us there and back; the equations diverge. No, we're talking about a photon being absorbed. Light has both wave and particle behaviors. Photons are most definitely quantum particles. Argument by quotation is pretty meaningless. Similar to the Wolff quote above, it doesn't add to any knowledge.

Light absorption and linewidth (split from A rational explanation for the dual slit experiment)
We're not in the frame of the light. The source of this is the energy-time uncertainty relation. ∆E∆t > hbar/2 The natural linewidth of any transition is related to its lifetime. And since E = hbar * w, you can see that this is just a relationship between frequency and time, which are Fourier transforms of each other. It's an inherent uncertainty from that.

A rational explanation for the dual slit experiment
"It is a wave" and "it becomes a corpuscle" is part of the overall problem. It's not that it is one or the other, it's that it has properties of both, and when you look for each of the properties, you will find evidence of that property. Via experiment we can only look for behavior. We can't say what it is, and also, we run into problems trying to use classical descriptions when describing quantum objects.

In a dark way, black holes are growing in mass with a new craze among cosmologists
! Moderator Note Yes, because you were spamming us with jibber-jabber that does not comply with our rules on speculations posts. This one does not, either. You need some combination of a model, a way to test your idea, and evidence in support of it. ! Moderator Note Yes, one must look at this. In this case, that is you, who must analyze the data and present it, because you are the one proposing a solution. You were told this before. It's not very promising that you are ignoring that.

Cancel Culture-Split from: Jordan Peterson's ideas on politis
It seems to me that this is just another in a line of boogey men: ill-defined, undefined or wrongly defined terms (when used by the group) that only serve to stoke fear in the base. Welfare queen. Political correctness. Socialism. CRT. Woke. Antifa. Cancel culture. Can you, or anyone, give a precise definition of cancel culture? (and explain how is it being “weaponized”?) And give some examples of someone being “canceled”? Seems to me that people claiming this are behaving as if they are owed attention, or business, and are complaining when held responsible for their actions. This might not be new, but we simply notice it more because of social media in this age of rapid and widespread communication

A rational explanation for the dual slit experiment
You’ve provided no evidence of the EM wave or any explanation of what properties (e.g. wavelength) they should have. Why don’t we detect them? What’s the source when neutrons or neutral atoms undergo interference? You concluded that particles don’t give a wave pattern, and that’s wrong.

Relativity equations are correct but possibly for different reasons than dilation of time and shortening of lengths.
Please don’t be obtuse. You are not being asked to support the doppler shift. You are being asked to support your claims that are contrary to mainstream physics. ! Moderator Note The thread on this was closed. You passed up your chance to make your case, and aren’t getting another bite at the apple. ! Moderator Note You were going against mainstream science, and you refused to provide the required model and/or evidence. Heaven knows why you think the same hand-waving tactic is going to work

I found out what Allais Effect based on
! Moderator Note And you were asked to present it, not spam us with this wall-of-text that you already posted in another thread. If you don’t comply with the rules, you will be banned

I found out what Allais Effect based on
! Moderator Note All I get from your post is “the more the Sun, Moon and the Earth's center have been aligned, the more disturbances have been observed” If you’re saying the video contains no further info, great. I don’t have to watch it. You still need a model and evidence

I found out what Allais Effect based on
! Moderator Note Check out the rules. Specifically this part of rule 2.7 Links, pictures and videos in posts should be relevant to the discussion, and members should be able to participate in the discussion without clicking any links or watching any videos. Videos and pictures should be accompanied by enough text to set the tone for the discussion So it’s stronger as you get closer to the equator? Great. Now all you need is a model and to present us with evidence. An opportunity to do real science.

NASA discovery proves Dark Matter doesnt exist and disproves standard model of cosmology [FALSE!]
That’s not what the redshift is - it’s not like having redder light at sunrise or sunset, because blue light has been scattered out if the path. It’s light of a known source, and thus known wavelength, shifted to the red.

A rational explanation for the dual slit experiment
“pattern” implies multiple data points, but that’s just semantics. The “dot on the wall” will appear only in areas that fit with the interference pattern, which is only going to happen if there is a wave. i.e. it’s because of the fact that the dot can appear where you would get first order interference, or second order, etc. that you must conclude there is a wave involved.

Wind Power Long Term Sustainability
The rotation rate changes all the time; the length of the day fluctuates on the scale of a millisecond over perhaps a month The angular momentum of the entire earth is basically constant, but that does not mean the rotation rate is. Mass moves around. Hurricanes/typhoons/tornadoes rotate and have angular momentum. Ocean currents change. The earth shape is slowly changing as ice melts (one of the suspects in the recent speedup of earth rotation) https://hpiers.obspm.fr/eop-pc/page_princ_frame2.html https://www.nasa.gov/centers/goddard/news/topstory/2003/0210rotation.html The variability of earth rotation is why it’s not used for precision timekeeping.

Could this be
You didn’t say anything about the transmitter being inside the cage. You talked about covering(!) it, and then about a reciever. Did you ever wonder why microwave ovens don’t cook food placed next to it? How do you transfer vector to something?
