#double slit

Slit this, slit that, and I can't concentrate because fanfiction RUINED ME!

Rick Rosner highlights quantum mechanics as the most “neat” physics discovery, still awe-inspiring a century later. He explains the double-slit experiment, where photons interfere with themselves, revealing how reality behaves under uncertainty. This shows physics as the mathematics of incomplete information, defying classical assumptions. Beyond quantum theory, Rosner speculates that the scale…

Light travels as a wave here (and not as a particle).

Observing The Universe Really Does Change The Outcome, And This Experiment Shows How

“The answer, disconcertingly, is that we cannot conclude whether nature is deterministic or not, local or non-local, or whether the wavefunction is real. What the double slit experiment reveals is as complete a description of reality as you're ever going to get. To know the results of any experiment we can perform is as far as physics can take us. The rest is just an interpretation.

If your interpretation of quantum physics can successfully explain what the experiments reveal to us, it is valid; all the ones that cannot are invalid. Everything else is aesthetics, and while people are free to argue over their favorite interpretation, none can lay any more claim to being "real" than any other. But the heart of quantum physics can be found in these experimental results. We impose our preferences on the Universe at our own peril. The only path to understanding is to listen to what the Universe tells us about itself.”

What do the quantum experiments we perform teach us about the nature of reality?

Is the Universe deterministic or non-deterministic?

Does physics only exhibit local phenomena, or does it have non-local phenomena as well?

Is the wavefunction a physically real entity, or just a calculational tool?
