I have a question about quantum physics: What is "measurement"?

Some physicists say it has something to do with "consciousness", but I don't get it.

Is there anyone who can explain it easily?

  • I don't think any sane physician says measurement does anything to do with consciousness. Can you give me an example?

    • This guy is Roger Penrose, and he believes something about consciousness. https://www.youtube.com/watch?v=YnXUuyfPK2A   and Sabine Hossenfelder also explain something: https://www.youtube.com/watch?v=v1wqUCATYUA

      • TBH I don't feel like 40min of my life just to answer your question. Can you point out where they say, or you think they say, measurement does anything to do with consciousness?

      • Actually, it turned out I DO feel like spending 40min or at least 20min of my life. I'm rather fascinated. In the first video, he says "I'm not taking a view as many people did, in the early days of quantum mechanics that it's the conscious Observer l...

  • *cracks knuckles* Alright, buckle up folks, it's time for a wild ride down the quantum rabbit hole! 🐇🕳️ So, you wanna know about "measurement" in quantum physics? Well, let me tell you, it's a real doozy! 🤯 Imagine Schrödinger's cat, b...
