Everyone wants something better than ΛCDM

There’s a nice short review article on arXiv today by Mike Turner. I wasn’t going to share it because it hasn’t got any pictures in it, but changed my mind.

Here is the abstract

The current cosmological paradigm, ΛCDM, is characterized (b) its expansive description of the history of the Universe, its deep connections to particle physics and the large amounts of data that support it. Nonetheless, ΛCDM’s critics argue that it has been falsified or must be discarded for various reasons. Critics and boosters alike do agree on one thing: it is the not the final cosmological theory and they are anxious to see it replaced by something better! I review the status of ΛCDM, provide my views of the path forward, and discuss the role that the “Hubble tension” might play.

arXiv:2510.05483

To make up for the lack of pictures in the article, here’s the first image that came up when I did a search for “ΛCDM”:

Big Things in the Universe

About a year ago I wrote a couple of articles (here and here) in response to the discovery of a very large structure (“The Big Ring“) and claims that this structure and others – such as a Giant Arc – were inconsistent with the standard model of cosmology; the work concerned was later submitted as a preprint to arXiv. In my first post on the Big Ring I wrote

To assess the significance of the Big Ring or other structures in a proper scientific fashion, one has to calculate how probable that structure is given a model. We have a standard model that can be used for this purpose, but to simulate very structures is not straightforward because it requires a lot of computing power even to simulate just the mass distribution. In this case one also has to understand how to embed Magnesium absorption too, something which may turn out to trace the mass in a very biased way. Moreover, one has to simulate the observational selection process too, so one is doing a fair comparison between observations and predictions.

Well on today’s arXiv there is a preprint by Sawala et al. with the title aims to assess the significance of structures comparable to the Giant Arc. The title of the paper is The Emperor’s New Arc: gigaparsec patterns abound in a ΛCDM universe from which you can guess the conclusions. The abstract is

Recent discoveries of apparent large-scale features in the structure of the universe, extending over many hundreds of megaparsecs, have been claimed to contradict the large-scale isotropy and homogeneity foundational to the standard (ΛCDM) cosmological model. We explicitly test and refute this conjecture using FLAMINGO-10K, a new and very large cosmological simulation of the growth of structure in a ΛCDM context. Applying the same methods used in the observations, we show that patterns like the “Giant Arc”, supposedly in tension with the standard model, are, in fact, common and expected in a ΛCDM universe. We also show that their reported significant overdensities are an algorithmic artefact and unlikely to reflect any underlying structure.

arXiv:2502.03515

Here’s a picture of a large structure (a “Giant Arc”) taken from a gallery of such objects found in the simulations

I quote from the conclusions:

We hope that our results will dispel the misconception that no inhomogeneity can be found in the standard model Universe beyond some finite size. Instead, any given realisation of the isotropic universe comprises a time- and scale-dependent population of structures from which patterns can be identified on any scale.

I have nothing to add.

[Перевод] Исследователи с DESI составили самую большую трёхмерную карту нашей Вселенной

С помощью 5 000 крошечных роботов в телескопе, расположенном на вершине горы, исследователи могут заглянуть на 11 миллиардов лет в прошлое. Свет от далёких космических объектов только сейчас достигает спектроскопического прибора Dark Energy Spectroscopic Instrument (DESI), позволяя нам составить карту космоса, каким он был в юности, и проследить его развитие до того, что мы видим сегодня. Понимание того, как развивалась наша Вселенная, связано с тем, как она закончится, и с одной из самых больших загадок в физике: тёмной энергией , неизвестным ингредиентом, заставляющим нашу Вселенную расширяться всё быстрее и быстрее. Чтобы изучить влияние тёмной энергии за последние 11 миллиардов лет, в DESI создали самую большую трёхмерную карту нашего космоса из когда-либо созданных, с самыми точными измерениями на сегодняшний день. Впервые учёные измерили историю расширения молодой Вселенной с точностью более 1 %, что даёт нам лучшее представление о том, как развивалась Вселенная.
