🔬✨ The craziest experiment in physics: the double-slit experiment!

As soon as we observe electrons, they behave like particles—without observation, an interference pattern emerges, as with waves. 🤯

👉 Information seems to change reality itself.

In the Zoomposium interview with Prof. Dr. Gerd Ganteför, we talk about the double-slit experiment, the limits of modern physics, and why our reality may be more than physics can explain so far.

Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.

I hadn’t been aware that the discovery of the wave-particle duality of photons, electrons and even larger structures of particles…

Let me add to the content for previous lecture.

Have you seen light moving like a wave?

No.

We only observe the results. (Wave-like pattern shown in screen)

But the same result is shown even if the light is a particle.

bright part is 2particle, dark one has no particle.

So interference pattern observation doesn't show the light is a wave.

This time, I'll put a thick plate behind the slit. move the thick plate. If light is a wave, there should be some changes in the bright pattern and dark one. dark spot will become brighter. However, there were only brightness changes to bright pattern and no phase differences or dark spot getting brighter. This shows that there is no light "wave" passing between the patterns. which you guys say interference is wrong.

<is interference pattern really wave interfering?>
