New preprint submitted to Classical and Quantum Gravity:

GR is time-symmetric. That symmetry is the root of singularities, information loss, and the arrow of time.

We propose the opposite: irreversibility is fundamental.

Main result: gravitational collapse halts before any trapped surface forms. C_max < 1. No quantum gravity needed.

Entropic I‑Field Theory: Fundamental Irreversibility and the Resolution of Singularities, Information Loss, and the Arrow of Time

General relativity is time-symmetric. This symmetry is the root of its three deepest puzzles: singularities, information loss, and the arrow of time. All existing approaches treat irreversibility as emergent — a statistical mirage atop a reversible microreality. We propose the opposite.   Irreversibility is fundamental. It is encoded in a classical scalar field $I$ — the I-field — that couples universally to gravity and matter. Its dynamics are governed by an Euler-Lagrange-Rayleigh action, where a dissipation term $\gamma u^\mu \nabla_\mu I$ breaks time-reversal symmetry at the level of the field equation. The modified Einstein equations introduce a dimensionless stabilization index $\eta$ that quantifies I-field backreaction.  The consequences are direct:  -   Gravitational collapse halts at a finite critical density $\rho_c$, before a trapped surface can form. The maximal compactness satisfies $\mathcal{C}_{\max} < 1$.  -   No event horizon ever appears — information remains causally accessible throughout the evolution.  -   The arrow of time emerges from the field dynamics, not from boundary conditions or statistical postulates.  Three foundational problems are thus resolved within a single classical framework, from first principles, without invoking quantum gravity.

The long‑term tracking of star S2 orbiting Sagittarius A* continues to be one of the most compelling confirmations of General Relativity. Over 27 years of observations show a clear Schwarzschild precession: the orbit doesn’t close but slowly rotates due to the intense curvature of spacetime near the supermassive black hole.
A beautiful example of how precision astronomy can test fundamental physics.

2/n…somewhat inelastic view of #GeneralRelativity , along with preferred avoidance of #Engineering.
Those likely to be recruited into a reverse engineering program setting are tasked with giving data on craft and observables context. #GR gives you a set of bounds at the origin , a starting point. In one approach to fitting for the data and observables you need your vehicle to become effectively massless. If you find a path to that you’ve not “ broken relativity “. Gravity will still be there...

I developed a new field theory of gravitational collapse — no singularities,
no event horizons, information preserved by construction.

The I-Field Theory: Fundamental Irreversibility and Gravitational Collapse Without Horizons

 We introduce the Entropic I-Field Theory, establishing fundamental irreversibility as a new physical principle through an Euler-Lagrange-Rayleigh action formalism. The framework extends Einstein's equations by coupling to a universal scalar field—the I-field—whose dynamics break time-reversal symmetry via an explicit dissipation term $\gamma u^\mu \nabla_\mu I$. The field couples to matter through $\mathcal{J} = \rho/m_I$, where $\rho$ is the energy density and $m_I$ the I-field mass scale, ensuring dimensional consistency.    We define the dimensionless **Stabilization Index** $\eta = (g_I^2 m_I/\gamma) \cdot [\lambda I^2/(\lambda I^2 + m_I^2)]$, which quantifies I-field backreaction strength and exhibits natural saturation behavior. Through rigorous analysis of the modified Friedmann equations, we prove that the I-field generates negative pressure $p_I \propto -\rho^2$ at high densities. This pressure opposes gravitational attraction, causing collapse to halt at a critical density $\rho_c$ where the acceleration reverses. The system reaches a finite minimal radius and subsequently re-expands, with maximal compactness $C_{\text{max}} < 1$ that precludes trapped surface formation.    The framework provides unified conceptual resolution of three foundational problems: (1) **Singularity avoidance**—gravitational collapse stabilizes at finite radius without horizons or curvature singularities; (2) **Information preservation**—the absence of event horizons ensures all information remains causally accessible; (3) **Arrow of time**—temporal asymmetry emerges from fundamental field dynamics encoded in the dissipation term, rather than from statistical postulates or boundary conditions.    The theory satisfies the correspondence principle, smoothly recovering general relativity in the limit $\gamma \to 0$ while preserving all established tests. This work establishes irreversibility as a fundamental rather than emergent feature of gravitational dynamics, extending physics from the time-symmetric framework of "Being" to the irreversible dynamics of "Becoming.

We spent six weeks computationally analyzing the Rodal (2025) warp drive metric, the latest attempt to build a warp bubble without exotic matter. The result is a definitive negative, but the reason why is more interesting than "it doesn't work."

The irrotational construction reduces violations by 37x vs Alcubierre. But observer-robust analysis shows it hides violations across 45% of the domain that comoving observers never see.

1/n Notes on #UAP Discussions : This particular exploration is a milestone. If we map what they eventually wind up talking about to vexing questions in current #Physics we have a direct confrontation with #GeneralRelativity, #QuantumMechanics, and the applied mass- energy firewall problem that lies at at the heart of several open problems in #Cosmology and the SM. It should be noted that the intuition of #Engineers in this case is capable of beating #Physicists to the punch.
There is a bit…

This is way above my pay grade, and I've only read the article, not the actual technical work underneath it (because my maths is insufficient to know what it's talking about, so there's not a lot of point). But it sounds really interesting.

I've never heard of "observer patch holography" (note typo in slug text), but a theoretical framework which has just a single free variable but lets you derive general relativity and the standard model, correctly predicting a bunch of magic numbers that we input as free variables into the standard model, is interesting as hell.

Maybe someone smarter than me has already looked at this and debunked it. Sabine doesn't seem to have done a video on it (or I missed it). And "one guy with four information theory axioms solves all of physics' problems" is definitely on the Hollywood-script end of the plausibility scale, but who knows? Weirder things have happened.

@cenobyte - thought of you, of course.

How Observer Patch Holography Improves on the Standard Model and General Relativity

The Standard Model can’t predict a single particle mass. General Relativity needs invisible matter to work. OPH solves these issues, and…

Unfortunately, this fails in both #physics and #theology.

The physics failure is in skipping part of the full energy–momentum relation. Energy does not imply mass. It implies mass or momentum. Photons have energy, but they do not have mass, for example.

The theology failure is that the Christian conception of God (the Father) is external to spacetime, i.e. transcendent. There's no metric tensor to apply. There's no general relativistic description for the relationship between God and the physical universe. General relativistic concepts like black holes do not apply.

Then you have the issue of God (the Son) as intercessor to deal with. Sins don't get sent straight to God the Father.

Good try. No cigar, though.

Physicists dream up ‘spacetime quasicrystals’ that could underpin the universe

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.
