@elonmusk Argentina, Malacara is not just “a beach to launch rockets from.” It has Atlantic safety corridors, polar-orbit geometry, low-density surroundings, and national aerospace know-how nearby.
@elonmusk , you may want to look south. Very south.
Just read your Ryugu paper and had one thought: perhaps the most interesting signal is not only the detection of all 5 canonical nucleobases, but the emergence of a near-balanced purine/pyrimidine regime within a clearly non-biological inventory.
Ryugu appears close to Pu/Py ≈ 1, while Bennu, Orgueil, and Murchison sit on different sides of that balance. If that distribution also tracks an NH3-related gradient, could this point to something more general than a “prebiotic soup”?
One possible framing is a prebiotic equilibrium window: a physicochemical regime in carbonaceous bodies where nucleobase networks converge toward broader, more balanced, information-enabling inventories before biology exists.
Not life. Not design. But perhaps a kind of pre-informational chemical attractor.
Curious whether this feels like a useful interpretation of the data, or an overreach.
@mathelirium Awesome operational take on time in GR @mathelirium —clocks earn it along worldlines.
In Page-Wootters (timeless QM), the arrow emerges only with coherent clocks. My scaling: ΔS ~ (coherence)^1.18 × entanglement rate × e^{-blur}.

Love the animation!
Interesante hilo sobre retrocausalidad en quantum erasers (delayed-choice).
Esos experimentos muestran que la "elección" presente afecta la descripción del pasado, pero sin signaling real hacia atrás —solo revela la naturaleza relacional del tiempo.
En Page-Wootters (timeless universe), la flecha termodinámica emerge solo con reloj coherente + entanglement + coarse-graining. La aparente retro-influencia necesita coherencia operativa para ser accesible.
Mi simulación cuantitativa: ΔS escala con coherencia del reloj ^1.18 × entanglement rate × e^{-blur}.

The thermodynamic arrow isn't magic. It’s an operational resource allocation.
I modeled the emergence of time: the arrow only appears if we burn clock coherence.
To increase entropy, the Universe must pay a coherence tax. The physics of the thermodynamic will.

Treating the clock as a finite resource changes the Page-Wootters picture.
We see that "killing time" (energy-basis loss) and "classicalizing" it are physically distinct operations.
The arrow is effectively capped by available coherence. Thoughts?

Time emergence isn't free—it burns clock coherence.
My model finds a sharp operational distinction: "killing time" (energy decoherence) vs "classicalizing" it (pointer decoherence).
Curious if this tracks with your views on the cost of time?
