From the overview: "Is the universe simple enough to be adequately described by the standard ΛCDM cosmological model which assumes the isotropic and homogeneous Friedmann-Lemaître-Robertson-Walker metric?" The more that question is asked, the more obvious it will be that the answer is no. |

Or is it the other way, the universe is simpler than LCDM? |

It could be a way to present our models if we send them via email. |

This is organized by the Royal Society, send your papers to the Philosophical Transactions of the Royal Society A if you want 'them' to look at your model. |

Great conference idea, helps promote alternatives to standard models |

I have not enough competence to present my theory there. Is there anybody who has a similar model and has competence to present it? It is simpler than Lambda model. 4D, and Q as diameter, eternal time. Different extrapolation as in BB. GR chanced to 4D, as in Suntolas DU, but no expansion. The theory of the Universe must say what is outside the observable universe too. There is the web of galaxies eternally and everywhere. The universe, the whole universe has no outside. Such place does not exists. And there is no beginning. The local universe goes like BB, but no expansion there either, except in the beginning of the Local Universe, the local big bang. Can be tested in astronomy: there should be visible different beginnings, different galaxy populations. |

Hi Oli, Toivo had a very succinct expression to describe the infinite and eternal Universe: Every thing evolves, but the whole does not evolve. He characterized the origin and expansion theory as hyperevolutionism. |

Very good! Everything evolves, but the whole does not evolve. Origin and expansion are impossible for the whole, the universe. Is it then a logical truth? What about my invention, that it is time, what is coming more, not matter, not space. It's only a little complicated because they are relative all four. |

genotics could be right |

Universe is the web of galaxies everywhere and always. If this can be proved right, it is a big invention. New theory. Totally new cosmology. The deep field images and the animations point to this direction. |

Challenges of Modern Cosmology 2024 (CMC2024) by Elena Asencio and Pavel Kroupa CMC2024 is an online discussion panel intended for listening, sharing and learning about challenges of modern cosmology and alternative theories. It will take place on the 18th of January 2024 from 12:00 to 17:00 (CET) and it will be publicly streamed on youtube. The panel will be divided in three sessions: current problems of modern cosmology, modified cosmology and gravity theories, and standard cosmological and gravitational tests. Each of these sessions will include from two to three 10 minutes talks followed by a 20 minutes discussion on the corresponding topic of the talk. In order to join the discussion panel, registration is still possible until the 10th of January. The discussion can also be followed online without registration by searching for "CMC2024" on youtube or through the link that will be shared on the CMC2024 webpage 24h before the event. |

The CMC-2 discussion panel videos of the presentations are on YouTube: Part I, Part II. My poster is available here. (Eric Lerner's slides are also there.) A more detailed calculation of the STz process is given in a pre-print of the paper submitted to the MG17 conference. It is posted on arXiv. This will help @HanDeBruijn understand the formula displayed here. My CMC-2 talk is here. Instead of presenting equations in five(+3) minutes, I decided to give a qualitative description through a familiar analogy. I'm not sure this is a better approach. (I received 'positive' feedback from three people, but 'confused' feedback from another.) |

"The energy that's been taken out from these photons is now in the form of heat, so I've represented the red dots here which are electrons that are heated by the process." - @RedshiftDrift As your model says that an electron gets heated, that means the electron increases velocity, right? Can you show conservation of energy and momentum? Specifically, a before and after for one complete interaction? |

Hi Louis,
I want to congratulate you and Eric on your presentation. Regarding the
Tired Light theory, I recall there being an issue with the redshift
spectrum (though I don't remember the details), and solving that problem is
a significant step forward. Unfortunately, my English isn't fluent enough,
so I usually don't participate in online sessions.
I wish you all the best,
Claudio

The list I give in Section "VI. Misconceptions about Tired-Light" can help
@sahil5d <https://github.com/sahil5d> debunk “Errors in Tired Light
Cosmology”

but it would be better, if possible, to debunk without using a specific
model.

Thanks Claudio. Let me know if you remember the specific issue with the redshift spectrum. |

All I have is a vague memory concerning the CMB, whose blackbody spectrum
would not be easily explained by interactions with other particles. I don't
know anything else.
