Fast radio bursts: bright FRB 20190203 detected at 111 MHz

Mystery remains for GRB theorists as to why no gamma ray transients can be found for non repeating FRB’s. https://arxiv.org/pdf/2410.13561

This lack of a gamma transient for this FRB is easily accounted for in my proposed theoretical model Here which describes the physical mechanisms responsible for the observed GRB  and FRB transients. An FRB in my model, is proposed to be simply a very fast, very short timescale GRB. 

FRB’s are just very short Gammaraybursts. Their observed activity in all frequencies are compressed proportionally on the timescale compared to their larger relative, the GRB. As an FRB has at most a second long transient in radio, it will have a proportionally much smaller transient time length in gamma. The observed total luminosity in each frequency would also in turn be proportionally less the shorter the observed transient length.


My model predicts here and on other pages of this blog that instead of the usually observed; seconds for gamma, minutes to hours for optical and days for radio transients normally seen in GRB’s, single FRB’s should have all their frequency transients durations on  much shorter timescales length. Notice that the entire observed radio transient for FRB20190203 was only in fractions of seconds. One only has to see that if a fast radio burst is only seconds long in radio frequencies, not for days as observed in the GRB radio transient, then it is clear that under my model, outlined in the link above, an FRB optical transient is predicted to be only on the order of a thousands of a second long. And in turn this model predicts that the FRB Gamma transient must  last for even shorter timescales in many order smaller than a thousandth of a second timescale. 

No wonder they can’t find optical or gamma transients for FRB’s. They are far too short to be recorded with our current technology

Fast Radio Burst mystery solved. They are short Gammaraybursts.

As usual the theorists haven’t the faintest idea about what mechanism produce Fast radio bursts and Gammaraybursts. In their ignorance they think imaginary massive explosions caused by imaginary black holes etc produce these flashes. Some fantasists have even imagined there is a time reversal structure, so desperate is their desire to try to explain why their “explosion” model always fails to model each successive new observation of either Gamma or Fast ray burst data. As these following links show:

The actual mechanism of gamma and fast radio bursts is well described by a simple classical model where light is a wave only. GRB and FRB data is only consistent with a model where the universe is infinite and not expanding. And the speed of light is always and only c relative to its source. In other words ignore the all relativity based physics.

DO NOT make up a fantasy model that continually needs to be corrected as the actual data comes in as all established models currently do. Instead base your model on the data first and foremost. Not as an afterthought. If you do, as I do, it will always correctly predict any subsequent new observation. As the link below explains.

https://physicsexplained.blogspot.com/2019/12/grb-190114c.html

To start with all current data on Fast radio bursts is consistent with them being just very short Gammaraybursts where the burst time line itself is so short that all data above radio frequencies occurs too fast to be measured by our instrumentation above the background noise. So for instance if a FRB is observed to last only seconds, then it’s optical counterpart will be a flash in less then a thousandth of a second and the gammaray part of the burst will last in even smaller timeframes of millionth of a second or less. Too small a time to be measured currently by our latest technology.

Proof of this model is that if one looks at any FRB lightcurve it will always show an exponential decay in peak fluence from hi to low frequencies. Proportional to wavelength. The fluence of the FRB lightcurve lasts for longer times at longer wavelengths. This same decay rate is also observed in all GRB data for all observed wavelengths. Confirming that an FRB is just a very short GRB. 

So that for instance if in a GRB, the gamma lightcurve peaks at t_0 seconds and lasts 20 seconds, then the xray peak will be delayed slightly and last longer. And this trend will continue. Optical peaks later than xray and lasts for even longer. And, the trend continues through IR, far Infrared through to radio. Where shorter radio wavelength parts of the electromagnetic spectrum of the burst will not peak for hours or even days after gamma peaks. And the radio lightcurve also lasts for days and weeks longer than gamma. This model is confirmed by ALL grb and FRB data since they were first observed in the 1990’s.

The delay and stretch of each part of the EM spectrum of any burst will always follow this rule. That is that it will peak and decay later and longer proportional to wavelength.

This model of mine first developed in 1990 when GRBs were not known even to be isotropic. And, not only did I successfully predict  in 1990 that they would be isotropic. I also succesfully predicted that similar rebrightenings in all other wavelengths and lightcurves would be observed to be delayed proportional to wavelength. When no such data had yet even been observed. Nor even considered possible by the fantasies of the ridiculous fact free Neil Gehrels explosion model.

And to date, 35 years later, my models predictions have always been confirmed with each successive year. Whilst the explosion progenitor model’s predictions have failed each year since 1990.


Links to my own theories articles and videos cited above describe in more detail how this “Doppler” effect of light in a classical model can explain all GRB and FRB data. 

But in a nutshell let me here offer a simple analogy: Imagine a gedanken of a flat surface of a large body of water. Create a series of waves of a particular wavelength on this surface. Now imagine you are on a motorboat travelling with and at the same speed as those waves as they propagate across the surface of the water. You don’t measure any up and down of the waves because your are moving at the same speed as those waves. Now speed up and slowly overtake these wavefronts. What do you see or measure? Your boat now bounces up and down slowly as it overtakes/passes each wave crest. Speed your boat up again and those waves will appear to you to be at an even higher frequency. Thus the faster your boat moves, the higher the observed frequency of those waves you overtake will appear to be. Do this same gedanken with lightwaves in a non BBT universe and you will get a GRB.

This is just a Doppler effect. That is what GRB and FRB’s are. No explosions involved

CERN particle Myth

Since the early part of the 20th C theoretical physics has using the standard model, attempted to describe the nature of atoms and light as being particulate. Ignoring the fact that almost all other scientific observations point to radiation being wave only and atoms as being only wave like resonating points in space. The only observation supporting the particle model are the observed "particle like" paths seen in cloud and bubble chambers and particle accelerator collisions. This video shows how the traditional explanation that these paths can only be caused by particles, to be a false assumption. By overlapping only 3 expanding wavefronts in 3 dimensions, all straight,curved, split,spiral,positive and negative paths observed in cloud chambers can be succesfully modeled using overlapping wavefronts only. I have produced a video of my own theoretical model of how particles are “created” in cloud chambers showing digital simulations of 3 expanding wavefronts and how they can recreate most if not all the observed "particle paths" seen in colliders.
I challenge anyone in the particle physics community: Give me a “particle path” and I’ll show you how it can be made by three overlapping wavefronts. No need for particles. Just as there was no need for an earth centered universe.

James Webb Space Telescope is expected to observe mature galaxy formation in early universe

Looking forward to having the JWST confirm the following observations. That mature galaxies are observed in any new deep field survey of the distant universe. Confounding the current predictions of BB theorists that JWST would confirm their predictions that no early mature galaxy formations would be observed in any new deep field survey conducted by the JWST. Note the theoretical physicists who have to date predicted that the JWST would see no new or early galaxy formation will rapidly make up new excuses to explain the failure of the BB model and its predictions. They will say...that they had predicted these galaxies in the early universe!! My guess is they will invoke "distortion of time itself in the early era of the Big Bang universe " to explain why the JWST observed mature galaxies where none were predicted previously by the BBT. Separate to this is my expectation that the JWST will also observe what I predicted on this blog for a decade and more and also as far back as 2001 on my www.gammarayburst.com webpage. That in the near and far infrared the delay in peak flux of gammarayburst afterglows will occur later and in longer wavelengths. A delay that will be Proportional to wavelength. The same wavelength/time delay relationship as seen in current observed Fast radio burst(FRB)decays in radio. Described currently on the wiki FRB page as: "The component frequencies of each burst are delayed by different amounts of time depending on the wavelength". In 2001 I described this expected delay as "proportional to wavelength". I expect this wavelength/delay in peak flux of GRB afterglows to be observed by JWST whenever it finally comes online later this year Why do I say this? Because the literature on the JWST suggests that it can observe multiple points simultaneously in its field of view at any wavelength of the electromagnetic spectrum within near and far infrared wavelengths. I assume this means the programmers of the JWST can observe GRB afterglows, if they feel inclined, in multiple wavelength observations from the *SAME* point in the sky simultaneously in different parts of the near and far infrared emr spectrum. My prediction is if they do make these observations of GRB afterglows they will not only confirm my models predictions, but also not be consistent with current established theory. Nor will they be able to explain these observations without admitting that their theoretical assumptions of a constant speed of light in all frames has been proved incorrect.

Gamma ray bursts and Fast radio bursts: A Theoretical model

Gammaraybursts and Fast Radio Bursts: A Classical Model.
This page was originally published 2000-2014 at gammarayburst.com

The following description of a GRB model can also be used to explain
more recent FRB observations. Essentially a FRB is a very fast GRB where
wavelengths shorter than radio are too short in duration to be observed.

In a non expanding universe of infinite age and size, observors should see
emr from all directions and from great cosmological distances. This assumes
a non Big Bang universe  not conforming to the laws of relativity. At these
scales some stellar sources will actually be moving away from the earth at
speeds greater than c. The earth then must be travelling away from the
source, at speeds greater than c and we would therefore overtake this light
and "see" the light in reverse. That is, what appears to be a flash above us is
actually light we are overtaking from the opposite direction below our feet.
Much as a fast boat can overtake slower waves on water and the waves
appear to be coming towards the observer in the prow of the boat when
in fact they are travelling in the same direction as the boat but at a slower
speed. Taking into account the assumption that we would always be
decellerating in relation to the source of the light, the burst would first
be seen as more blue shifted (at the gamma end of the spectrum) and as
time progresses observations in longer wavelengths would be observed.
So the original gamma lightcurve profile would be seen stretched out
over longer time frames in longer wavelengths . If the burst was for
20 seconds in gamma and 200 in optical and then it would be seen for
2000 sec in radio. But always show the same distinctive profile for each
burst in various parts of the observed spectrum.
For a brief visual explanation of this see..
http://www.youtube.com/watch?v=QLSfmvFcLB8

The model I describe here predicts that the afterglows in different parts
of the emr spectrum will be similar in profile to that of the gammaray
lightcurve, but with different timescales. This is consistent with all
observations and shown in the illustration below. The graph below shows
this in data from grb 970508. Using gamma, optical and radio observations.
The prediction would be that other unmeasured lightcurves like x-rays
would also have similar profiles as their counterpart in gamma.
The shorter the wavelength the shorter the timescale. That is; in x ray
the burst duration would be shorter than optical and longer than gamma.
In the comparison graph below, between the 3 lightcurves,  a self
similarity of lightcurve profiles from different parts of the emr spectrum
is observed. The length of the afterglow is directly proportional to the
wavelength. It also indicates that if  gamma and optical burst time lengths
very were small, on the order of smaller than milliseconds. Then in radio,
these bursts would be observed having time scales in millisconds. And
that there would be measurable delays between shorter and longer
radio wavelengths. This is confirmed by recent Fast Radio Burst
observations.
