Always blows my mind to think about all the shit we just don't know yet.
Its bullshit.
Short answer is on micro scale "observing" is never a passive action and better name is "measuring". You have to interact with a particle to observe it and this interaction changes its properties, so the experiment result is different.
For all the people puzzled by it, it's not the sentient act of looking at it or the measure being read by a conscious entity. As long as the electron captor is on, you'll only get two slides. It's because they use light to detect electrons, meaning that light will interact with them, and in order to interact with them, the electron must focalize, and thus can't be a wave anymore. Turn off the light and it'll be a wave again
We are right, as long as you don't look at the results!
That's Young experiment right?
Delayed-choice quantum eraser is weird than the slit experiment.
Isn't this what gave rise to the theory of parallel universes? Over 2 decades of my life I've never seen a meme about this and would've had no idea what this meant but I just learned about it a few days ago, life's weird
It is easily testable, yet we still don't have a clue.
