Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Many Worlds interpretation of quantum mechanics proposes that every time a quantum event gets decided, the universe splits so that every possible outcome really does occur. But where exactly are those worlds, and can we ever see them?

Damn, I ended up in the universe where this doesn’t make any sense

I actually thought the whole universe splits at every wiggle. Recombination makes this far more confusing and even more interesting. It also makes me wonder if there could be something like a partial, local, or pocket-like split, where a split is still attached to or recombines with its origin.

I love that this channel covers alternate quantum interpretations with more technical vigour than the average YouTube science video

I love that many topics like the double slit experiment are briefly explained again, to build refreshers for non-physicists like me. This helps me still get the most out of the video- thank you for the great content

Wow, that was a great explanation! A pond analogy somehow feels much better to me than a branching tree. I'm not sure if I'm a fan of the many worlds interpretation, but I think after watching this video I understand it better (obviously on my very shallow, amateur level). Thank you!

My brain has just split into two migraines. This is heady stuff

At risk of sounding oblivious, where is that guy who always acts as the quantum observer from? Those visuals are hilarious.

I think PBS Spacetime may be my favorite educational media on youtube, for both being informative and in depth but also often tackling topics just on the horizon of my current understanding. Not something I've seen before, but not something I don't already have the foundation to understand. Really often I'll be wondering about something and there'll be a spacetime video about it within a month or two.

It had never occurred to me that the many-worlds interpretation would be so efficient with regards to space.
