Massive props to @rbos for pointing out this video to me.

The tl,dr if you don't want to watch the whole thing: It begins with the idea that #cosmological "fine #tuning", often used as an argument to 'prove' the idea of intelligent design, is almost certainly just an observational illusion. But the rabbithole goes much deeper than that.
Why We Might Live in a "Barely Habitable" Universe

The emergence of globular clusters and globular-cluster-like dwarfs: https://www.nature.com/articles/s41586-025-09494-x -> "a suite of #cosmological simulations in which both dark-matter-free GCs and dark-matter-rich dwarf galaxies naturally emerge in the Standard Cosmology. We show that these objects inhabit distinct locations in the size–luminosity plane and that they have similar ages, age spread, metallicity and metallicity spread to globulars and dwarfs in the nearby Universe. About half of our simulated globulars form by means of regular star formation near the centres of their host dwarf, with the rest forming further out, triggered by mergers. The latter are more tidally isolated and more likely to survive to the present day. Finally, our simulations predict the existence of a new class of object that we call ‘globular-cluster-like dwarfs’ (GCDs)."
The emergence of globular clusters and globular-cluster-like dwarfs - Nature

The results from a state-of-the-art suite of hydrodynamical cosmological zoom-in simulations show how globular clusters naturally emerge in the Standard Cosmology and also reveal the existence of a new class of object called globular-cluster-like dwarfs.

Buddhist #mythology serves as a symbolic, pedagogical, and #soteriological tool, conveying #ethical values and #cosmological insights. Unlike mere superstition, it functions as skillful means (#upaya), integrating local cultures and supporting the path to #awakening through narrative and metaphor. Here is a brief overview:

Interesting theoretical approach to #quantum #gravity using quantum information theory and tie it to gravity. What emerges is a small #Cosmological constant (a.k.a. Dark Energy), consistent with current measurements:

Gravity from entropy: A radical new approach to unifying quantum mechanics and general relativity

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our understanding of gravity and its relationship with quantum mechanics.

#BigBang Theory is the prevailing #Cosmological model for the universe. It states that the universe began with a very hot, dense state and has been expanding and cooling ever since.

Big Bang

The Big Bang event is a physical theory that describes how the universe expanded from an initial state of high density and temperature.

Technical trials for easing the (cosmological) tension

Thanks to the dizzying growth of cosmic observations and measurement tools and some new advancements (primarily the "discovery" of what we call dark matter and dark energy) all against the backdrop of General Relativity, the early 2000s were a time when nothing seemed capable of challenging the advancement of our knowledge about the cosmos, its origins, and its future evolution.

"There is all this #cosmological evidence for the existence of #DarkMatter, but over the last 30 years, we’ve run all these experiments and haven’t found it. My bet is that we’re looking at things all wrong. Someone who’s 8 years old 🧒 today is going to come around and figure out how to make sense of all the data without evoking mysterious new substances." https://www.astronomy.com/science/discussing-dark-matter/
