The Quantum Experiment that Broke Reality | Space Time | PBS Digital Studios

One of the best explanations of the double slit experiment I've seen. I almost understood it.

My brain is in a superposition of understanding and being completely baffled by this.

"If you understand quantum physics, you don't understand quantum physics." -Some smart man

The Double Slit has always been once of the most fascinating experiments to me. I guess they figured this video had enough mind-blowing information since they didn't mention that when sensors are placed at the slits to try and identify which slit the particle chooses, the pattern on the screen disappears and is replaced with just two columns.

I'm a programmer, and this 100% sounds like an optimisation in the simulation, reducing processor load and removing the unneeded calculation unless it's needed for the observation of those within said simulation. This experiment is the first one that actually gives me pause to believe the theory that we live in a simulation

The types of people watching this (amazing by the way!) channel: The adamant student The anxious philosopher The disgruntled scribe The confused Joe The Sims sims (those who truly believe believed ideals to be believable even though they don't know why) The intrigued intellectuals The PhD sentinels The 2: 00 a.m lurker and finally stoners

When i first found out about this experiment and its implications it felt like i was dreaming. Its literally as if a pseudoscience from a scifi movie becomes real life. Very cool and amazing

Kind of makes me think of those moments when you feel like you've transcended that moment, feel like you've caught a brief glimpse of infinite possibilities, before you make a decision which solidifies your trajectory to the next moment. Or maybe I should just call it a night and go to sleep 😂

This stuff fascinates me but what astounds me even more is the engineering aspect of these experiments, an aspect which I never see anybody explaining. For example, how the heck do you build a machine which will fire a single photon? How do you test that it's working?

I swear this reality is the strangest I've ever experienced

U forgot the best part..!! When they observed which slit the partical went thru, the pattern changed back to that of particals. Only being changed by the ACT of being observed..🤯

I'll always remember how my rotund general chemistry professor illustrated particle-wave duality by bobbing up and down and walking to and fro for an auditorium of hundred and fifty students

this will be patched in the next update

It's amazing that there are videos like this, that explain quantum physics in a way that people like me, who aren't scholarly or fully educated in physics, that we can begin to understand how this incredible aspect of reality, well, our perceptions of reality, work on such scales. I love learning about this. Thank you, PBS for always being part of my learning life, since i was a very small child. Now that's amazing. ❤😘🌹

I've felt like we've been in a different reality for six or so years now. The world just seems incredibly mental.

I had to pause at 4:48…..that almost broke my understanding of the standing of things. I need 5 minutes before I let yo continue

Its a fascinating experiment. So fascinating that I decided to have a go at doing it myself a few years ago. I managed to get hold of a photomultiplier tube from a surplus store. Build the required special power supply and a water cooled pelter based cooler to take the tube down to -25C which reduces the dark current to the point where single photon detection becomes possible. Using a slice of CD as the diffraction surface with a synchronous motor to rotate it and and led in a box with a pinhole as the light source. It actually worked by passing the anode current directly though a pair of headphones, it sounded like the patter of rain. Turning the led current down you could hear the individual click of photons been detected. The way the volume went up and down clearly showed the diffraction patten.

your music and visual artists are awsome but I believe they get too little feedback for their amazing work, and every unseen contributor to the quality of your videos

Omg I love this series. It helps me build on my work SO exponentially. Thank you 🙏

What messed me up here was finding out a bucky ball did that. I'd thought it was only known to happen at the quantum level, so I'm even more confused now!
