Thomas young's double slit experiment proved light behaves like a wave by creating an interference pattern that only waves can produce. He shown light through two narrow slits cut into a barrier and recorded the pattern on a screen behind it.

Thomas Young's double-slit experiment, performed in 1801, is one of the most important demonstrations in physics. It provided strong evidence that light behaves as a wave by producing interference patterns. In the experiment, coherent light is directed at an opaque barrier with two closely spaced slits. The light waves passing through these slits interfere with one another, creating a pattern of bright and dark fringes on a screen positioned behind the slits. The spacing and location of these fringes depend on the light's wavelength, the distance between the two slits, and the distance to the screen. This experiment established the wave nature of light. The modern understanding of wave-particle duality, where light can also behave like particles (photons), developed in the early 20th century with quantum mechanics, and is beautifully illustrated by modern versions of the double-slit experiment performed with individual photons.

The double-slit experiment is a key demonstration in quantum physics that reveals the strange behavior of particles like electrons and photons. In the experiment, particles are fired at a barrier with two slits, and a screen records where they land. If both slits are open and no measurement is made, the particles form an interference pattern, like waves overlapping, even when sent one at a time. This suggests that each particle passes through both slits at once in a state called superposition. However, if detectors are placed at the slits to observe which path the particle takes, the interference pattern disappears. The particles then behave like classical objects, going through one slit or the other. This change in behavior simply from observing the system is known as the observer effect, and it highlights a fundamental principle of quantum mechanics: measurement affects the outcome. The experiment challenges our understanding of reality, showing that at the quantum level, particles don't have definite states until they are observed 🤓

Sabine Hossenfelder On The Double-Slit Experiment: "You either have to accept a faster-than-light update of the wave function… or you have to accept that the future is fully determined already." Einstein called it "spooky action at a distance." The wave goes through both slits. Measure at one slit, the other slit updates instantly, even if the particle never hits your detector. The particle somehow “knows” you’re trying to measure it.

$Diffraction through a single slit: As we narrow the slit, diffraction dominates, spreading light out, revealing its wave-like nature. Widen the slit, and the beam straightens up, its width starts to mirror the slit, just as expected. #physics #optics #fourieroptics #light #photonics #python$

Magnetism can behave like a spectrum like light. In the Searl Effect, a rotating magnetic field forms a sine-wave pattern where energy flows along the wave. Like a river: the oscillating magnetic field becomes the channel that guides moving charge and energy downstream.

$Built an FDTD Maxwell solver from scratch and rendered 45 seconds of it. What you’re watching: A plane EM wave hits a PEC barrier with two slits 90 cells apart. λ = 26 cells. The slits diffract. The beams interfere. Fringes form. Then a biconvex dielectric lens (ε = 3.8) refracts the transmitted field and partially focuses it. Young’s double-slit experiment. Fresnel diffraction. Snell’s law refraction. All emergent. None of it coded in it falls out of four update equations on a 480×480 Yee grid. This is what Maxwell’s equations actually look like when you let them run.$

Remember the description that whistleblower Dylan Borland gave in regards to the light pattern seen on a giant triangular UFO that he saw while stationed at Langley AFB in the summer of 2012? Borland: "There were four lights in total. One light on each corner, and a larger light in the center.” Well, check out this stabilization of an eerily similar craft and light pattern seen in Sonoma, CA in Dec 2025. Woah. Stabilization edit on Reddit Original video on YT

Neuralink implants can currently control cursors and recreate mental images on a screen, but another goal recently showcased is turning brain waves into physical actions. In this demo, Neuralink, recorded neural signals that are creating movement through a Tesla Optimus arm.

I finally got around to watching Sabine's double slit video and I wasn't impressed. She starts by claiming there's nothing special about the double slit experiment while downplaying the results, but then contradicts herself by admitting no one can explain how the faster than light update 'spooky action' occurs. Sabine ends the video by saying people should study this. Yeah, people like her. The answer to the double slit experiment is that everything is connected all the time via an invisible extra dimension of energy. The Dirac Sea. The Aether.

In 1887, Heinrich Hertz noticed that some light made it easier for electrons to escape a metal surface, but the pattern made no sense under Classical Physics. The surprise was that very bright red light could fail, while dim blue or ultraviolet light worked immediately. Einstein explained this in 1905 by proposing that light comes in energy packets, and only packets with enough energy can knock electrons free. That was the Photoelectric Effect, and it helped earn him the 1921 Nobel Prize in Physics.

Few realize how close we are to a complete Physics revolution. Particle physics is about to be replaced by quantum-wave theory. There is no inconsistency between quantum and macro. Mass is energy. Standing waves produce coherence. The double slit experiment is the gateway to our new understanding. Think about what the answer must be. The electron is traversing all possible paths. How? Space is not empty. All points in space and time are connected. We can travel faster than the speed of light.

YouTuber AlphaPhoenix pulled off something that sounds impossible. He recorded a laser moving across a room at 2 billion frames per second. That is fast enough to watch light itself travel, something the human eye can never perceive in real time. The camera he used was not a normal high speed camera. It recorded only one pixel at a time. To build a full video, he fired the laser again and again, each time recording a single pixel from a slightly different point. After thousands of captures, he stitched the pixels together into a full frame sequence that reveals the light wave moving through space. It is a mind bending mix of physics and creativity. The end result lets us watch one of the fastest phenomena in the universe at a speed we can finally understand.

Drop a ring magnet on a double ferrocell and light itself maps the field: nanoscale iron chains align in the fluid and act like tiny mirrors, blooming into a glowing flower of symmetry. You’re not seeing magnetism, you’re seeing light bent by its geometry

SCIENTISTS TURN LIGHT INTO A MEMORY SYSTEM Scientists built a tiny photonic chip and sent identical photons through it, expecting messy quantum behavior. Instead, the light started acting like a memory system, forming patterns that match a classic AI model used for associative memory. In simple terms, the interference between photons did the math needed to store and recall patterns. No brain, no computer, just light physics doing the computing. Source: NewsForce

What technique has helped engineers make airplanes safer? Hint: this technique can help us reveal small flaws in various materials long before we discover them. The answer is holography. The technique was first invented and developed by 1971 physics laureate Dennis Gabor. In the 1940s and 50s, Gabor discovered a way of producing images with the illusion of depth. The method was based on interference – interaction between light waves – and coherence – light waves aligned in phase with one another. Light falling on an object is captured on photographic film along with a reference beam. When only the reference beam falls on the developed film, the light is bent so that a reproduction with depth is produced. This content was created as a co-production between Nobel Prize Outreach and the BBC.
