The physics of an O'Neill Cylinder, rotating fast enough to create artificial gravity through centrifugal force. Inside, objects curve "upward" because motion replaces mass, and every part of the habitat follows the same circular path. (Via scienceclic)

Forget the “trampoline” analogy; it’s a 2D lie. Gravity isn’t a pull. It’s the metric deformation of a 4D manifold. Every mass is just a localized curvature gradient forcing the geodesics of spacetime to converge. You’re not “falling.” You’re simply following the path of least resistance through a warped continuum where Gμν = 8πTμν. The universe has no floor; only a geometry that refuses to stay flat.

The arm doesn't "catapult" into release, it unwinds from the inside-out along a spiral path as a result of trunk rotation.⁠ ⁠ This centrifugal force pulls the elbow into extension and allows the natural whip-like mechanism to occur. 🌪️⁠

A common misconception in physics is that gravity must be negligible at the quantum scale because its measured strength appears weak compared to electromagnetism and the strong nuclear force. However, this perception arises from considering gravity only in its weak field limit. Obviously, it will appear weak under such conditions, but the situation changes when we consider regions of high mass-energy density. For example, when examining strong gravitational fields near black holes, the force becomes immensely powerful. With this in mind, lets re-examine unification and gravity at the quantum scale: Following our holographic mass solution, elementary particles like protons are found to be microscopic Schwarzschild black holes and their mass-energy density is sufficient to create a gravitational curvature equivalent to the strong nuclear force. The vacuum energy density of space provides enough energy to maintain these structures through Planck-scale dynamics, preventing their rapid evaporation via Hawking radiation, so they are ultra-stable. These discoveries, expounded in our studies like The Origin of Mass and the Nature of Gravity, available to download for free on CERN's Zenodo preprint server-🔗 -demonstrate that what we observe as distinct fundamental forces are in fact manifestations of a unified force operating at different scales, where quantum vacuum fluctuations significantly curve spacetime (the curvature being gravity) with the resulting encapsulation generating screening effects that modulate the apparent strength of gravity from its fundamental high-energy state, which results in nuclear confinement forces, to its familiar weak-field behavior that appears as regular Newtonian gravity.

The Dance of Three Masses on a Warped Spacetime Fabric Newtonian Gravity says masses attract one another through force. General Relativity changes the picture by treating gravity as geometry itself, where matter shapes Spacetime, and motion follows that evolving curved structure. In a three-body system, the bodies are not just pulling on each other. They are moving through a geometric landscape that shifts as the mass arrangement changes.

Why does a spinning object speed up as it shrinks? This Hoberman sphere demonstration illustrates the law of conservation of angular momentum. Moment of inertia measures how mass is distributed relative to the axis of rotation. When the sphere collapses, its mass moves inward. This decrease in inertia forces the angular velocity to increase because the total momentum of the system must remain constant. This same principle allows figure skaters to accelerate their spins and causes collapsing stars to become rapidly rotating pulsars. It is a fundamental rule of physics. Geometry determines speed.

A Triple Spring-Mass Pendulum Just for The Fun of Physics We model the mass positions as r₁ = (x₁, y₁), r₂ = (x₂, y₂), r₃ = (x₃, y₃) with y positive downward in the simulation. The three spring segments are r₁ = r₁ − (0,0) r₁₂ = r₂ − r₁ r₂₃ = r₃ − r₂ Each spring applies a Hooke force along its own direction, F(r; k, L) = −k (|r| − L) (r / |r|) and each mass also feels gravity, Fgᵢ = (0, mᵢ g) So the equations of motion are m₁ r̈₁ = Fg₁ + F(r₁; k₁, L₁) − F(r₁₂; k₂, L₂) m₂ r̈₂ = Fg₂ + F(r₁₂; k₂, L₂) − F(r₂₃; k₃, L₃) m₃ r̈₃ = Fg₃ + F(r₂₃; k₃, L₃) We integrate these ODEs forward with RK4 using a small dt. Different scenes come from changing the mass ratios and from giving the third mass a small initial kick. The yellow trail is the path of the third mass. The inset phase portraits show the same motion in state space: (x₃, vₓ₃) and (−y₃, vᵧ₃) When those curves stay tight and loop cleanly, the motion is more regular. When they spread, fold, and smear, energy is being redistributed across the whole chain between gravity, spring stretch, and kinetic motion. #NonlinearDynamics #CoupledOscillators #SpringPendulum #ChaosInMotion #ComputationalPhysics #MathematicalVisualization

WHAT IF GRAVITY ISN’T A FORCE - BUT THE SHADOW OF AN EXTRA DIMENSION? Point → line → square → cube. 0D → 1D → 2D → 3D. Now connect 2 cubes. Wait. What the hell do you even get? That’s the 4th spatial dimension - and no, your brain can’t picture it. But your body feels it every second. Mass doesn’t pull on space. It bends it. Curves it into a direction you can’t see - but live inside. That strange invisible push? That’s gravity. Not down. Not up. Sideways through the universe. Welcome to the part of reality you were never supposed to notice. (And don’t even ask about the 5th. That’s where timelines blend.) Source: scribblemouth_

Pure mechanical poetry. This cutaway of a classic Pratt & Whitney R-985 gives a perfect view inside a 9-cylinder radial aircraft engine. Seeing the pistons fire in a perfect circular sequence to deliver smooth rotary motion through that central crankshaft is highly satisfying. The master rod system handling all that synchronized power is an absolute masterclass in vintage engineering.

Why do we clean the core of our engines when the planes are flying through the rain? Shouldn’t the rainwater be enough? Many people believe that rain naturally cleans aircraft engines during flight. However, this is not true. Although rainwater does enter the engine intake, it is mostly thrown outward by centrifugal force in the compressor section. The rotating blades cause the water droplets to move toward the outer casing of the engine, where they are drained away and do not reach the internal gas path where dirt and deposits accumulate. Gas Path Cleaning is the process of cleaning the internal airflow path of an aircraft engine, especially in the compressor and turbine sections. It removes deposits like dust, soot, oil, and salt that build up during operation. This cleaning improves engine efficiency and fuel consumption, maintains engine performance, reduces component wear by lowering operating temperatures. 📸 by ig/muc_maintenance Not an ad

Physics is often taught in dry equations but Walter Lewin turns it into an edge of your seat thriller. He proves that the laws of nature are not just suggestions they are absolute. By releasing the ball from exactly 2.5 times the radius of the loop (h = 5/2 R) he demonstrates the perfect balance between gravitational potential energy and the kinetic energy required to maintain centripetal force. Watch as the math comes to life and the ball defies gravity through pure conservation of mechanical energy. This is what happens when you stop memorizing formulas and start witnessing the universe in motion.

"The only way to reach 1,000 terawatts of AI power is with a mass driver on the Moon. Most of the hardware would need to be produced locally on the Moon, and because it has no atmosphere and only one-sixth of Earth's gravity, AI satellites could be launched into deep space using an electromagnetic mass driver instead of rockets." — Elon Musk

Physicist Brian Greene demonstrates gravity in the simplest way possible using a bottle full of water. When the bottle is held still water streams out through the holes because gravity creates pressure inside. But the instant he drops the bottle the leaking stops completely. Bottle and water fall together at the same rate so the water becomes weightless relative to the bottle. It is a perfect demonstration of Einstein’s idea that gravity and acceleration are deeply connected. What feels like weight is often just the result of the frame you are in.

The basic idea behind "UFO physics" is very simple. We can get a strong "upward" force from a fast-spinning magnet (or magnetic flywheel), because it "pushes against space" like a spinning gyroscope. Very easy, if we apply a rotating magnetic field (3 or 5-phase) to that magnet! The problem is that such an "upward" force is accompanied by an equal and opposite "downward" force by Newton's 3rd Law. So we see an increase of gravitational potential, but no loss of total weight ("up" plus "down"), unless that spinning magnet goes into "free fall". How to solve this great problem? The E.T. crop artists have suggested (many times) that we should try to change that "downward" force into another kind of force, which does NOT follow Newton's 3rd Law: namely the Lorentz force of electromagnetism. As shown in a video below, added DC current makes a disc magnet spin rapidly in one direction (by the Lorentz force), while other thin wires which supply that DC current spin in an opposite direction. We can see right away, that the mass of that disc magnet is perhaps 100 times more than the mass of many thin wires which surround it below. Yet they spin in opposite directions at approximately the same speeds! This shows that spin angular momentum (m x v x r) is NOT conserved, due to a peculiar sideways action of the Lorentz force. Does everyone understand so far? In summary, if we can change the "downward" force, for an upward spinning-magnet, into a Lorentz force, then we should have NO real "downward" force, but only a force that goes "up"! So that will be my next experiment. I have had to order some specialized parts to make the trial apparatus correctly, but will try to do it in October, after all needed parts arrive.
