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.

"Quantum mechanics is incomplete right because it doesn't explain the collapse of the wave function." Sir Roger Penrose discusses the missing link between the smooth evolution of the Schrödinger equation and the sudden collapse of the wave function during measurement. Could this "gap" be the key to understanding the mind? Credit: TheInstituteOfArtAndIdeas

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.

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.

This is what happens when a quantum wave-function hits a wall that it does not have enough energy to cross. Part of it goes through anyway. This is the famous "tunnel-effect". A particle without quantum properties cannot do that.

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 🤓

Nobel laureate Sir Roger Penrose dismantles standard cosmology, arguing the Big Bang wasn't the beginning and quantum mechanics is fundamentally wrong. He then connects a real, gravitational wave function collapse to the non-computational nature of consciousness and why today's AI can't truly understand.

Is entropy subjective? Entropy is core to the laws of thermodynamics and the arrow of time. And yet, some physicists argue that entropy actually depends on who is measuring it. Could it really be the case that such a fundamental aspect of the laws of physics is subjective?! I addressed this question in my talk at the Rationalist Festival (Rat Fest) 2025, organised by Conjecture Institute. Watch here or on the YouTube link below!

$A droplet “walking” on a vibrating fluid can mimic quantum physics, forming diffraction patterns just like electrons in the Kapitza-Dirac effect. A rare, visible model of wave-particle duality, letting us watch quantum-like behavior in the macroscopic world.$

Erwin Schrödinger’s 1926 equation turned quantum mechanics into wave dynamics. Instead of tracking a particle by a sharp trajectory, you evolve a complex wavefunction whose shape and phase carry the physics.
