Hi Matt, thank you very much for your honest comment at 16:03 during an entire minute about the _Janus cosmological model_ by French astrophysicist Jean-Pierre Petit. This is so rare in the English-spoken world to hear about these ideas! It makes me want to translate your whole episode in French language. Will do it soon. BTW, let's say that ALL theories are by essence speculative. Good theories try (and are able) to describe our _physical reality_ (i.e. accounting for observations and measurements) and they also make _predictions_ so they can be _falsified_ (in the sense of Karl Popper). On the contrary, bad theories don't even bother to be falsifiable (there's a lot of them!) or are already falsified. It is the natural cycle for a good dominant theory to be superseded by a better one, someday. I don't know if the Janus model or another bigravity theory will prove to succeed where lambda-CDM will fail (which is quite difficult, as the lambda-CDM model is very adjustable thanks to its various free parameters that can be fudged to stay in accordance with many new observations over time, a bit like the _Ptolemaic Epicycles_ ). But the proof is in the pudding: the Janus model can already account for observations with fewer free parameters and can also explain observational facts the concordance model cannot. Have a look for example at such comparison points in _Astrophys Space Sci_ (2018) 363: 139. doi:10.1007/s10509-018-3365-3 It will be interesting to see if the Janus model has its own explanation for the solid discrepancy between CMB ringing and stellar recession speed measurements, hence in the surprising discovery that the density of "dark energy" may have different values through space and time. Cheers

@AlcyonEldara

5 жыл бұрын

Could you stop lying please ? "Less parameters". Of course, when you use "variable constants", you don't call them "free parameters". Which is a big fat lie. You need to add a free parameter for the rate of change and assuming A LOT. "Can already account for observations". Another lie. JPP claims to explain everything but always put the "right" numbers (=free parameters, and differents for every "explanation") and sometimes he just claims "my model works" without providing math. He also don't have a CMB or a baryon accoustic oscillation. We don't observe any divergent lensing. And let's not even talk about the dark matter in janus. Dark matter = matter that don't interact with "regular" light. The current model is saying "we don't know what this DM is, so we don't assume anything". JPP add a full set of untestable predictions (interactions, speed of "negative" light, etc), his model isn't even a scientific model. And I am not even talking about how JPP insults everybody who dare to point the flaws in his "model".

But it was a bit misleading, because those "rings" are only a 2D observation with our eyes (like the plane of the milky way in the sky) whereas in reality the sound shell did expand radially as a 3D bubble in all directions, as I thought initially. This is important to point out, as redshift measurements are not restricted to a 2D plane.

Good point and observation. The Universe (4D) isn't a collection of ripples in a pond (3D) that constructively (or destructively) interfere with each other.

Basically, it said comoving distance. Since the measurements of the galaxies that are farther away are from farther into the past, you have to evolve all the distances you obtain forward or backward in time, and bring them all to the same moment. That way you get a picture of the universe at a single moment where you can compare distances independently from its expansion. Depending on what moment you chose, the distance for the bump can really be anything. It only has physical meaning when you know the moment as well, or its corresponding redshift. I assume they mention that in the paper, or there might be some standard choice, like the lss.

You wouldn't have heard of it😉

I would love a textbook that puts all of these videos together in a nice way!

That episode was so cool. Hearing about how a theory hypothesised something, then they found the data to support it is cool enough. When it's regarding the structure of the universe, it's way cooler.

Who slipped and thumbs down? Because that could not have been on purpose. How can you dislike this?!

Really liked that you showed the data analysis in this episode! (Referring to the overlapping rings)

Thank you for theses theoratical lessons. They seem so real.
