Youtube is always safe from malware. I understand if you never follow links to videos from non-youtube or non-vimeo sources, but you can always hover your mouse over the link before you click on it, and see at the bottom of your browser where it leads to. This link does indeed link to youtube.A_Seagull wrote: ↑Mon Dec 03, 2018 1:47 amWhy should I care?

Yes you have a slight misunderstanding regarding the experiment. The particles do not interfere nor interact with previous or succeeding particles.
The particles interfere with themselves. They are best modelled as a wave which goes through both slits. Each slit then acts as a wave source. The waves emanating from each slit then interfere with each other. This results in a sequence of highs and lows at the detecting screen. These highs and lows, can be considered to represent the probability that the detector will detect a particle at that particular point. It requires a whole lot of particles to build up the pattern so that it can be seen. Each particle is entirely independent of every other.
Hope this helps.
If what I posted doesn't aid your understanding, well that is absolutely fine with me.
If you want to learn about the 2 slit experiment then wikipedia would be a better source of information than youtube. Or even better.. read a book. Or better still do your experimentation.. its not hard to see the diffraction pattern using light.
- or - you could simply copy/paste the link into your browser, or at the very least go to youtube and search:
"The Quantum Experiment that Broke Reality".
And you can always trust PBS Space Time, because PBS Space Time is, although slightly popular science, in the more serious business of popular science.
It explains what actually happens, it is non-fiction, serious and trustworthy.
You can't do the double slit experiment properly using your own light. First of all, you need a laser - not hard to get though.
But you cannot fire single particles (photons/electrons) using home made equipment.
If you fire a single electron, one at a time at the 2 slits, you still get the interference pattern after firing many of those single particles, one at a time.
This is why I am talking about the thing that the first particle "tells" the second particle where to land on the screen, to create the overall picture of an interference pattern.
This is also described in the video, as well as Wikipedia, as well as in science books.
