Can the #dhamma solve all the world’s problems? Are there any problems to solve or is the world in exactly the state it needs to be in, always? Will reducing #suffering by transforming #desire into #contentment have a meaningful impact in time to avert the #polycrisis? Is the polycrisis a fiction we use to divert attention from our personal suffering? So many questions. So much time to fail at answering them, if we zoom out to a broader #cosmological perspective that may not seem “natural” but …

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.

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)."

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:

#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.

Here's the next Sadler's Lectures podcast episode on Immanuel Kant's Prolegomena To Any Future Metaphysics, this one focusing on the two "dynamical" antinomies he examines

Here's a Sadler's Lectures podcast episode on Kant's discussion of the cosmological ideas in his Prolegomena To Any Future Metaphysics, and four antinomies emerging in that analysis

"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/

The third & fourth antinomies in the dialectic of pure reason, as Kant develops it in his Prolegomena to Any Future Metaphysics are "dynamical" and deal with causality. Here's a core concept video discussing them

In the core concept video series on Kant's Prolegomena, we now move into the discussion of the "cosmological ideas" in part 3 of the work. We run into four antinomies within the dialectic of pure reason

The consensus is that any laboratory #mass must be attracted by the Earth, although some authors have considered the #cosmological consequences if #antimatter should be repelled by #matter.

In the general theory of relativity, the weak equivalence principle requires that all masses react identically to #gravity.

Here we show that #antihydrogen atoms behave in a way consistent with gravitational attraction to the Earth.

Repulsive #antigravity is ruled out.

Evidence for suppression of structure growth in the concordance #cosmological model: https://arxiv.org/abs/2302.01331 -> The #universe caught suppressing cosmic #structure growth: https://news.umich.edu/the-universe-caught-suppressing-cosmic-structure-growth/

Constraints on the #HubbleConstant from #SupernovaRefsdal's reappearance: https://arxiv.org/abs/2305.06367 - the result of 67(+/-4) km/s/Mpc is in hard conflict with numerous other methods that cluster around 74(+/- a few) but funnily in accordance with determinations from the CMBR. So the famous tension re. this most fundamental #cosmological number, which is turning 10 years old this year, is getting more intriguing than ever ...

No Tension - #JWST #Galaxies at z>10 Consistent with #Cosmological Simulations: https://arxiv.org/abs/2304.13755 - "we use results from the Renaissance simulations, which are a suite of high resolution simulations designed to model galaxy formation in the early universe. We find that the most massive galaxies in Renaissance have stellar masses and star formation rates that are entirely consistent with the observations from the JADES and CEERS surveys."

The #secrets of deep #space may be starting to reveal themselves, as rapid advances in #technology and stronger research collaborations are making it possible for #astronomers to piece together #cosmological clues like never before.

150 (or so) Arguments for #Atheism

"A popular view in contemporary #analytic #philosophy of #religion is that while there are many arguments for #theism -- #cosmological, #ontological, and #teleological arguments; #moral arguments; arguments from #consciousness; etc. (...) -- there are only one or two arguments for atheism, viz., the problem of #evil and (more recently) the argument from #divine hiddenness.

This is a misconception. Here are well over 150"

Searching through existing data spanning 9 billion years, a University of Michigan #physicist and colleagues have uncovered the first evidence of “#cosmological coupling”—a newly predicted phenomenon in #Einstein’s theory of gravity, possible only when black holes are placed inside an evolving #universe.
