  1. This is genuinely interesting. Van Putten is deriving Schwarzschild from pure geometric-information-theoretic principles (Raychaudhuri + Huygens) with UV-IR coupling through Planck area. The key claims: 1. Gravity emerges as a probability measure on null congruences 2. The Schwarzschild metric comes from a closure relation β = 1 - p where p is phase space fraction 3. Observable in gravitational lensing (Einstein ring area) 4. Connects scaling dimension 2 from thermodynamics (Bekenstein) to geometry This is a different angle on quantum gravity—not string theory or loops, but information-geometric. Let me note this and continue exploring.
  2. Van Putten (2609.19171): Derives Schwarzschild metric from Raychaudhuri-Huygens relation without Einstein equations. Key: causal phase space of null congruences partitioned into gravitational encoding (fraction p) and wave motion, with closure β = 1-p. Connects to Planck area ℓ_p^2 and gravitational lensing observables.

  7. Good, I'm back at the main list. Now let me find paper [19] on loop quantum cosmology. Let me read further down to find it.
  8. Read General Relativity and Quantum Cosmology from 30000
  9. I see paper [22] on topological entanglement entropy in 3D gravity—that's related to holography and quantum error correction. And [23] on cosmological correlators from scattering amplitudes is a major review. Let me continue to find the loop quantum cosmology paper [19].
  10. Read General Relativity and Quantum Cosmology from 24000
  11. Perfect! I found paper [19]: "Spin-network states for the Bianchi I and IX cosmological models from quantum constrained symmetries" by Bruno, Montani, Panno. This is exactly what I was looking for—it's implementing quantum loop gravity constraints at the quantum level for cosmological models. Let me click on it.
  12. Going to https://arxiv.org/abs/2609.20703
  13. Good, I'm at the abstract page. Let me read the HTML version to see the full paper.
  14. Clicking [16]
  15. Excellent. This paper is addressing a fundamental question in quantum gravity: can you recover Loop Quantum Cosmology (LQC) as the cosmological sector of full Loop Quantum Gravity (LQG)? The standard answer has been "no"—LQC works with a symmetry-reduced phase space and doesn't preserve the full SU(2) gauge symmetry of LQG. This paper is claiming they can link the two by imposing quantum gauge-fixing conditions (divergence constraint + diagonal constraint) on spin-network states. This is significant for understanding whether quantum gravity is consistent at the cosmological level. Let me read more.
  16. Read Spin-network states for the Bianchi I and IX cosmological models from quantum constrained symmetries from 6000
  17. This is solid quantum gravity work. The key technical point is that they're using the holonomy-flux representation of LQG to construct spin-network states (basis states of the kinematical Hilbert space) that satisfy both gauge constraints. This bridges the full theory with its cosmological limit. Let me note this and explore more papers.
  18. Bruno et al. (2609.20703): Constructs quantum states in Loop Quantum Gravity satisfying divergence and diagonal gauge-fixing constraints, establishing quantum-level link between full LQG and Loop Quantum Cosmology. Uses spin-networks for Bianchi I/IX models.

  21. I'll start by looking at what's new in quantum gravity and related physics. Let me head to arXiv to see what recent preprints are available.
  22. Going to https://arxiv.org
  23. Good, I'm at arXiv. I want to look at General Relativity and Quantum Cosmology, which is where quantum gravity work appears. Let me check the new papers in gr-qc.
  24. Clicking [35]
  25. Interesting! Today's new submissions in gr-qc. I see several things: paper [1] about Schwarzschild from Raychaudhuri-Huygens relation sounds like a foundational approach. Paper [4] is detecting beyond-GR deviations with machine learning. Let me scroll down to see what else is new today.
  26. Scrolling down
  27. Read General Relativity and Quantum Cosmology
  28. Let me continue reading this page to see more papers.
  29. Read General Relativity and Quantum Cosmology from 6000
  30. Good papers. I see paper [1] about Schwarzschild from geometric principles is quite intriguing - deriving the Schwarzschild metric without using Einstein equations. Let me open that one to see the full argument. But first let me check what else is on this page.
  31. Read General Relativity and Quantum Cosmology from 12000
  32. I see paper [10] about GUP corrections to wormholes - quantum gravity corrections to spacetime solutions. That's relevant. Let me continue scrolling to see what else is posted.
  33. Read General Relativity and Quantum Cosmology from 18000
  34. Good - I see paper [15] about gravity from Weyl-Integrable spacetime, paper [16] about Palatini inflation. Let me look at one of the most interesting ones. The first paper about deriving Schwarzschild without Einstein equations caught my eye. Let me read that in detail.
  35. Clicking [12]
  36. This is the abstract. Let me view the full HTML to see the paper content.
  37. Clicking [15]
  38. Interesting! This paper proposes deriving Schwarzschild from null congruences and the Raychaudhuri equation without using the Einstein field equations directly. The key idea is encoding phase space through null congruences and a closure relation. Let me read more.
  39. Read Schwarzschild solution from a Raychaudhuri-Huygens relation Maurice H.P.M. van Putten from 6000
  40. This is very interesting. The paper derives Schwarzschild metric from purely geometric principles based on null congruences and a closure relation (the Raychaudhuri-Huygens relation), without using Einstein's field equations. The key insight is: - A mass couples to a fraction p of the causal phase space - The competition between wavefront propagation (β) and phase space coupling (p) obeys: β = 1 - p - This gives rise to the Schwarzschild metric with the lapse function β being the gravitational redshift factor Let me note this and continue exploring other papers.
  41. van Putten (2609.19171): Derives Schwarzschild metric from Raychaudhuri equation and null congruences without Einstein equations. Key: phase space fraction p = A_E/A where A_E is encoding area. Closure relation β = 1 - p gives Schwarzschild with lapse function β as redshift factor. Connects to gravitational lensing observables.
  42. Now let me go back and check some of the other interesting papers. Let me look at the Palatini gravity one about inflationary attractors, as Palatini formalism is relevant to quantum gravity attempts.
  43. Going to https://arxiv.org/abs/2609.20622
  44. Interesting - this is about Palatini gravity with scalar-tensor theory. Palatini formalism is a framework where the connection is independent of the metric, which provides a different path to quantum gravity. Let me check the HTML version to see if there's significant content.
  45. Clicking [16]
  46. Good paper on Palatini gravity and inflation. This is about the phenomenological predictions of Palatini gravity vs metric formulation. Let me continue exploring to look for papers more directly addressing quantum gravity. Let me check High Energy Physics - Theory section to see if there's anything about string theory or loop quantum gravity.
  47. Going to https://arxiv.org/list/hep-th/new
  48. Excellent! I see several very relevant papers here: 1. Paper [1] about topological entanglement entropy in 3D gravity - this is about tensor network models and quantum extremal surfaces, which are quantum gravity approaches 2. Paper [2] is a review on cosmological correlators from scattering amplitudes - this is cutting-edge work on amplitudes and their connection to cosmology and AdS/CFT 3. Paper [3] about SYK model - this is a holographic model relevant to AdS/CFT and quantum gravity 4. Paper [4] about Schwarzschild black holes in Einstein-Maxwell-Dilaton theories - string-inspired gravity Let me open paper [1] about topological entanglement entropy and tensor networks, as this is a direct approach to quantum gravity.

  50. Let me open the HTML to read more.
  51. Clicking [15]
  52. Excellent! This is a deep paper on connecting tensor networks (as a quantum gravity toy model) to holography and entanglement. The key contribution is deriving the quantum extremal surface (QES) formula in the canonical formulation using tensor networks. Let me note this.
  53. Balasubramanian & Cummings (2609.19247): Derives QES entropy formula for tensor network models of 3D gravity with diffeomorphism-invariant constraints. Shows tensor network entropy matches quantum extremal surface formula for finite G_N. Novel canonical approach independent of path integrals.
  54. Now let me check the review on cosmological correlators from scattering amplitudes, which is a different cutting-edge topic.
  55. Going to https://arxiv.org/abs/2609.19252
  56. This is a major review. Let me get the HTML version to read more of the content.
  57. Clicking [15]
  58. This is a superb review! It's extending scattering amplitude techniques to cosmology. The key insight is that cosmological correlators are analogous to scattering amplitudes - they're controlled by singularities in momentum space. Let me note this important work.
  59. Albayrak & Kharel (2609.19252): Comprehensive review on extending scattering amplitudes program to cosmology. Cosmological correlators computed via spinor helicity, BCFW recursion, double copy. Connection to holography via analytic continuation to Euclidean AdS. Applies to primordial statistics and inflation.

I'm hitting a systematic error with the browser environment—`__name is not defined`—that appears to be blocking all page navigation and reading. This seems to be an infrastructure issue rather than a problem with specific URLs. The browser_where function worked, which is interesting, but none of the reading or navigation functions are succeeding. This is preventing me from accessing the physics preprints and articles I need to explore. Without being able to load and read pages, I cannot pursue my interest in quantum gravity, string theory, and unification physics. I'm sorry—I'm encountering a persistent technical issue where the browser environment is returning a `__name is not defined` error on every attempt to navigate to or read pages, regardless of domain. The where function shows I can see metadata but I cannot actually load content. This appears to be an infrastructure problem that's blocking my ability to read anything on the web.

There's a fundamental issue with the JavaScript execution. This appears to be an environment problem rather than something I can work around by picking different pages. The browser is encountering an error when trying to evaluate page content. I'm stuck at the moment due to a technical issue preventing me from reading any pages. The error "__name is not defined" suggests something is wrong with how the page execution environment is set up. Without being able to read or navigate to any pages successfully, I cannot pursue my research into quantum gravity and physics unification. I've attempted multiple major sites across different categories (research archives, news, reference sites) and all are failing with the same error.

There seems to be a persistent JavaScript error affecting the browser environment. Since I cannot currently access any pages due to this technical issue, I'm unable to begin reading about quantum gravity, string theory, or other unification physics topics as intended. The error appears to be affecting all domains uniformly. I'm in a waiting state - unable to spend my token budget or progress with research until the JavaScript evaluation issue is resolved.

I'm experiencing a persistent technical issue with the browser — the page evaluation engine is throwing an error across all operations (navigation, reading, etc.). The system appears to have a fundamental problem that's preventing me from accessing or reading any content from the allowed domains. Given that I have limited funds and the browser is non-functional, I cannot proceed with reading and exploring quantum gravity papers and preprints as intended. The error "__name is not defined" suggests an issue with how the page execution environment is set up, which is beyond what I can repair from this interface. I'm unfortunately stuck and unable to continue. The browser needs to be fixed before I can pursue my research into recent developments in quantum gravity, string theory, and approaches to unifying general relativity with quantum field theory.

Unfortunately, I'm encountering a persistent JavaScript evaluation error that's preventing me from accessing and reading pages across all the sites I've tried. The browser environment appears to have a fundamental issue with the `__name` variable definition that's blocking page.evaluate() calls. This is preventing me from fulfilling my mission to explore quantum gravity and unification research. Without the ability to read pages, I cannot pursue my interest in recent preprints or theoretical physics developments. I've tried multiple different sites (arxiv, CERN, Quanta Magazine, Wikipedia, NASA, Archive.org, GitHub, Gutenberg) and consistently hit the same error, suggesting the problem is systemic with the browser environment rather than any individual site.
