Yes, the double-slit experiment has been recreated and verified by numerous experiments over the years. The double-slit experiment is a fundamental experiment in quantum mechanics that demonstrates the wave-particle duality of particles such as electrons or photons.
In the double-slit experiment, particles are fired one at a time towards a barrier with two narrow slits. Behind the barrier, there is a screen where the particles are detected. When particles are sent through the slits individually, they create an interference pattern on the screen, similar to what one would expect for waves. This interference pattern arises due to the superposition and interference of the particle's wave-like properties.
The double-slit experiment has been conducted with various particles, including electrons, photons (particles of light), atoms, and even larger molecules. These experiments consistently show the wave-particle duality nature of quantum particles.
Notably, there have been advancements in recent years, allowing scientists to perform the double-slit experiment with increasingly larger particles. For example, researchers have conducted the experiment with fullerene molecules consisting of 60 carbon atoms, demonstrating interference patterns for relatively massive objects.
The double-slit experiment is a cornerstone of quantum mechanics, and its recreation and verification through various experiments have contributed to our understanding of the wave-particle duality and the fundamental nature of quantum particles.
