Gravity might be holographic

Gravity Seems Holographic
Holographic Gravity

Interesting. Scientists are still divided as to whether this means we exist within a hologram, but it's an interesting solution to the puzzle of gravity. As said in the second link:
"In SEAT, spacetime curvature, traditionally seen as a consequence of mass and energy in Einstein’s general relativity, is reinterpreted as an effect of entropic gradients. Structured information on boundary surfaces creates entropy gradients that influence spacetime, resulting in the observed “curvature.” This “entropic order” refers to the level of organization in the informational structure around an object, ultimately altering the geometry of the surrounding space. It also refers to the arrangement and organization of information that creates a directional flow of entropy, leading to structured, predictable behavior in the system. This entropic order affects the motion of nearby objects, giving rise to gravitational behavior akin to spacetime curvature."

"Holographic gravity in the SEAT framework challenges traditional views by describing gravity as an emergent macroscopic effect from quantum information on boundary surfaces. This unified model ties together quantum mechanics, thermodynamics, and gravity, resolving issues like the black hole information paradox and providing a new understanding of the universe. SEAT suggests spacetime curvature results from entropic effects due to structured information at boundaries, offering a novel perspective where gravity is a consequence of statistical mechanics and informational dynamics rather than a standalone force."

Reading theoretical physics makes my brain hurt. There's simply far too much imagining of concepts that I find very hard to grok.

Last night I was talking with my son, who studies CO math - Combinatorics and Optimization, and I asked him what concepts bother him or that he finds challenging. He referred to some logic seminars where people were busy proving the mathematically impossible through logic statements. It all gets a little surreal for me, just like reading these physics papers where paradox abounds.

I think my favourite quote was, "Somehow, we and everything we experience exist within an unblinking dot of no size." That really sums it up for me. It makes me feel like I need to return back to living in a simple material world where gravity just is, and that's why I stay away from falling objects.
