Why it acts like both a wave and a particle and gets stranger still.
If you remember the double-slit experiment from school, this video is a super accessible refresher and a reminder of just how weird light really is. It behaves like both a wave and a particle.
But it gets even stranger. When scientists tried to record which path the photons took (slit 1 or slit 2), the wave pattern disappeared. Even more baffling, this happened even when they recorded the path after the photon had already hit the screen.
Stick around until the end of the video to see the quantum eraser in action. So very weird.
Oh, and of course the related videos has a video by Sabine debunking the quantum eraser idea.
Ha, what a rabbit hole. What she says makes total sense. I’m going to watch her bomb video next.
I asked ChatGPT to explain what’s going on. It went way over my head. Further study is required.
