Thank you for viewing this video on Sky Scholar! This channel is dedicated to new ideas about the nature of the sun, the stars, thermodynamics, and the microwave background. We will discuss all things astronomy, physics, chemistry, and imaging related! We hope that the combination of facts and special effects will aid in learning even the toughest concepts in astronomy. If you enjoyed this video, please subscribe.
Pierre-Marie Robitaille, Ph.D., was a professor of Radiology at The Ohio State University from 1989-2019, and also held an appointment in the Chemical Physics Program. In 1998, he led the design and assembly of the world’s first Ultra High Field MRI System. Readings from this equipment brought into question fundamental aspects of modern thermal physics, such as Kirchhoff’s Law of thermal emission.

The technical content of this video is way over my head but the premise is clear. Main stream science data fudging. Thanks Pierre

[@tisithecount4198]

I think Pierre needs to get to scientific meetings and start convincing astrophysicists. He has the science to back him up, so why not?

The picking and choosing of what will fall on the face of a white dwarf shows that the theory of very dense white dwarf as an explanation must fall flat on it`s face.Thanks Doc for another excellent video show I am looking forward to the next example of real science defeating fanciful stuff.

[@captainsensible298]

It seems as though Astronomy in general terms has fallen prey to "making shit up" as they go along trap. Instead of changing the hypothesis to fit the measurements as measuring equipment has become more accurate, the researchers simply add unmeasurable, unrepeatable, bizarre new features to the existing hypothesis. So fixed in the paradigm they cannot see the wood for the trees. This is what happens when research is controlled by people with no imagination and or no courage. Thank you for all your presentations, all your work is truly appreciated and we are thankful for your dedication to bringing us enlightenment.

[@FrederickMathieu]

Francois Wesemael was my thesis supervisor. Wow!

[@stevecrothers6585]

[@critical-thought]

Another excellent presentation! It is amazing how scientists subvert observations to fit their model. Very backward - science doesn’t work that way (or at least shouldn’t).

[@ineffable500]

Thank you again; and, a comment which echoes my comment on your last video as well: the only reason the fanciful ideas presently entertained by astronomers which you address in these videos are at all possible is dependent on the present fact that we can actually observe and perceive so extremely very very little of the Universe, and in particular, we cannot resolve any angular diameter of the points of light which we call stars (except for, it is presently claimed, about 2 dozen, albeit barely even in these cases).

[@lmwlmw4468]

Great video.

[@EasyThere]

How do they eliminate the light years worth of dust and gas in the gap between the star and observer?

[@VariantAEC]

Wondered that for more than 20 years now.

[@VariantAEC]

That said, the argument here is that the current scientific understanding is that accretion disks, intense gravity of hyperdense objects, and photolevitation are all equally responsible for the Balmer lines of white dwarf stars even in cases that contradict themselves, which obviously makes no sense. This just exposes the nonsense of modern astrophysics and cosmology.

[@briankerr4512]

astral hoover

[@MA9ICAL]

Dr., what is necessary from an equipment or hardware perspective along with resolutions of magnifying or spectral analysis? In other words, how close do we need to be to actually use the science we now understand, to discern what we are actually looking at. What do you imagine we need, and how is it being developed. The conflict you have so eloquently explained in your lecture seems to take so much of the energy of the individuals involved in the formation and forging of these ideas. We need to not have the conflict and just observe. Our answers are there. We just need to increase our focus and resolution. Thank you for addressing sir, if you read this. Good day, and Cheers

[@Chris.Davies]

Pierre, I watched a couple of videos the other day where the creators are very accepting of the Liquid Metallic Hydrogen nature of our so-called "Gas Giants" (Surely: Liquid Giants!) and rendered it as a liquid surface in their videos. So, the message about LMH is getting out there, it just has yet to penetrate all the way to the inner solar system! Why would planets be made from LMH, but suns get made from gas? How would that even happen? Because a sun is simply a "Liquid Giant Planet" that got so hot and heavy particles started fusing somewhere in, on, or above the surface. Yeah?

[@romado59]

There is five or six ways to create redshift not counting chemistry. The issue is with figuring what percentage each adds to the total. Could there be a way to filter the percentage of each redshift from the total?

[@billjasin8388]

Dr. Robitaille, I am curious, If white dwarf stars are not super dense, is there another plausible explanation for how Type 1A Supernova form? I love your videos keep up the deep dives. Your explanations sure seem to make a lot of sense. Thanks for what you do.

[@raycar1165]

Very good Much❤Love

[@Celtokee]

1. Why do you suggest that calcium is "floating in the atmosphere" of the white dwarves? Wouldn't it also emit lines if it were solidly one the surface, atop denser mass below? 2. It is an assumption that red shift is due to velocity. There are other explanations for red shift, e.g., super-dense gravitational fields (as are theorized for WDs).

[@szymonbaranowski8184]

gravitational stuff is just new hype

[@chrimony]

I like how the patchwork theory becomes "no doubt".

[@jasonwarren9279]

What are the spectral lines like for, say, Venus or the moon? Are we able to recreate these lines in a lab with light emitting devices? What sort of spectrum is produced through things like the light flash produced when a cavitation bubble in water collapses?

[@JoeDeglman]

If anything, redshift indicates a lesser atomic/ magnetic flux density, or some other intrinsic property of the object. Definitely redshift does not correspond with a higher density nor a doppler recession, for most objects.

[@Steaphany]

What of type 1A Super Nova of White Dwarfs which is supposed to be the result of exceeding the Electron Degeneracy pressure ? Is there any grounds to claim Type 1A Nova being standard Candles ?

[@stevecrothers6585]

No, none!

[@7eroBubble]

Modern astronomy's house of cards, building one imaginary thing upon another, has finally reached the height of the stars (seems to be a lot of hot air surrounding stars, these days). A very great collapse is due, that is, reputational, not gravitational. Seems that some of astronomy's purported super-giants may actually be dim dwarves, after all ;-)

[@henrysiegertsz8204]

If observation disproves the model, that is unacceptable. At all costs, the current model must be supported by any means necessary!

[@AndrewPrice2704]

Has not a metal scar or blemish been observed on a WD recently? If so, the change in this, or its absence, should provide some interesting data :)

There is no mistake in the video. If you examine Zuckerman's et al. cited below the video, you will see that the authors refer to Mg I, just as Dr. Robitaille stated (see abstract and Fig. 2 legend).

[@paaao]

If you place a strong magnet underneath a ferro cell, you will notice bright pin points that form along the most constructive zones of magnetic/dielectric interference. A galaxy is no different. The black hole at the center where the larger dielectric rest convergence accumulates, leads to constructive and destructive lines of force outward at a massive scale. Any metallic matter free floating in space will accumulate at these points just like the ferro fluid giving rise to highly constructive metallic objects that become compressed and begin nuclear processes as a result. It's really not as complicated as everyone thinks. No one is looking at the bigger picture. All magnetic and dielectric field lines give rise to both birth and death of material matter. This happens over large scales and large time frames, but it isn't magic. Star birth follows a very mathematical frequency line that obviously varies due to chance, but stars are not born via complete chaotic processes that happen to all align perfectly and repeatedly.

[@2Hesiod]

The orbital dynamics prove they are hyper-dense.

Not it doesn't. Clearly you did not understand Dr. Robitaille's lecture. White dwarfs are not ultra-dense at all. And they are not gaseous.
