New Gravity Theory: Emergent Orbital Motion in a Bidirectional Flux Field

Presenting a field-based dynamical model in which stable circular orbits emerge naturally from bidirectional directional-energy lines that form a flux field, without invoking a central attractive force or prescribed orbital equations. Using a computational simulator as a physical analog, I demonstrate that mass body entering such a field spontaneously acquire orbital motion at multiple radii, with conserved speed and long term stability. The results suggest that orbital behavior can arise from directional field geometry rather than force-based attraction, offering an alternative conceptual framework aligned with flow-based interpretations of gravitation.

Below is the link of simulator and its explanation.

did u know spinning black holes drag spacetime around them such that if you’re close enough you MUST orbit and cannot stay stationary, bc the actual fabric of space is being pulled

Physicist Sir Arthur Eddington was vital in arranging two simultaneous expeditions in 1919 to demonstrate the bending of light around a star during an eclipse. With storm clouds clearing just thirty minutes before the eclipse, Eddington was able to prove the theories behind General Relativity and popularise Albert Einstein outside of Germany. Eddington was also the first person to describe the process of fusion in stars.

From Kastoria, Greece, to the frontier of relativistic astrophysics, Theodora Papavasileiou shares her journey through theoretical modeling, black hole physics, and computational precision. In this conversation with Homer Dávila for SKYCR, she reflects on extreme gravity, high-energy processes, and the intellectual discipline required to explore some of the most demanding environments in the universe.

What ACTUALLY Happens at the Planck Length | Sleepy Scientist Stories

At the Planck length — just 1.6×10⁻³⁵ meters — the universe stops behaving like anything we know. Space and time dissolve into quantum foam, and even gravity begins to shimmer with uncertainty. In this episode of Sleepy Scientist Stories, we’ll journey to that hidden frontier — where black holes, strings, and quantum geometry collide. What truly happens when we try to zoom in beyond reality’s final boundary?


Loop quantum gravity (LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case.


It is an attempt to develop a quantum theory of gravity based directly on Albert Einstein’s geometric formulation, general relativity. As a theory, LQG postulates that the structure of space and time is composed of finite loops woven into an extremely fine fabric or network. These networks of loops are called spin networks. The evolution of a spin network, or spin foam, has a scale on the order of a Planck length, approximately 10−35 meters, and smaller scales are meaningless. Consequently, not just matter, but space itself, prefers an atomic structure.

Einstein’s Cosmic Twist: Dying Star Reveals Spacetime Dragged by Black Hole

Imagine the universe not as an empty stage where cosmic events unfold, but as an active participant in the drama. Imagine the fabric of space and time itself being a dynamic entity, capable of being bent, stretched, and even twisted by the immense objects within it. For a century, this was a profound prediction of Albert Einstein’s theory of general relativity, a concept so strange it was…

it’s the matter and the local observer making the measure and the scale. e=mc².

i just had a thought. because of general relativity even slightly below light speed travel would allow for the traversal of distances with near instant time to the passengers. the rest of the world will have a lot more time pass but not the passengers. with AFAL (as fast as light) travel no matter the distance it would seem instant (excluding time for acceleration and deceleration)

Time travel forward in time: laughably easy, just travel really fast in space! (or orbit close to the event horizon of a supermassive black hole)

Time travel backward in time: you either need an infinitely long cylinder, an object with negative mass, or a spinning naked singularity, none of which exist in nature.

like seriously, the fact that the three major methods scientists have come up with for going back in time require the existence of things that cannot exist tells me that the universe is built in such a way to explicitly prevent backwards time travel from occurring.

Light and black holes

For those interested in black holes and light deflection, I recommend this site. There are 2 “summary” pages and 2 “studies” pages, a little more technical.

The site explores the calculation of light deflection in a gravitational field generated by a massive object or a black hole, according to classical mechanics or general relativity (Schwarzschild or Kerr). It also describes the main characteristics of astrophysical black holes and features visualizations and animations illustrating light bending, photon trajectories and orbits around them.

The site also includes a French version.

Lumière et trous noirs

Pour ceux intéressés par les trous noirs et la déviation de la lumière, je recommande ce site. Il y a 2 pages “synthèse” et 2 pages “études”, un peu plus techniques.

Le site explore le calcul de la déviation de la lumière dans le champ gravitationnel d’un objet massif ou d’un trou noir, selon la mécanique classique ou la relativité générale (Schwarzschild ou Kerr). Il décrit également les principales caractéristiques des trous noirs astrophysiques et présente des visualisations et animations de la courbure de la lumière, des trajectoires et des orbites des photons autour de ceux-ci.

Le site comporte également une version anglaise.

WHAT’S THE EP = EPR HYPOTHESIS?

Introduction

The EP = EPR hypothesis (pronounced “E-R equals E-P-R”) is a fascinating, though still speculative, idea in theoretical physics. Proposed by physicists Leonard Susskind and Juan Maldacena, it suggests that quantum entanglement (EPR) and wormholes (ER) are two sides of the same coin. In simpler terms, the EP = EPR hypothesis proposes that when two particles are entangled, they are…
