For German speakers, I also recommend Josef Gaßner's YouTube series "Von Aristoteles zur Stringtheorie" (I find it a bit more structured than PBS Space Time, albeit maybe less amusing).
It seems to be well produced but the presenter rubs me the wrong way for some reason.
I came here to reccomend this channel aswell. The "basics" were all covered years ago (6+), and now Matt is dipping into more complicated topics. If you find his recent videos overwhelming, I suggest to give his older ones a try.
I love watching this channel even though it sounds like word salad to me
Judging by the comments, that seems to be a common sentiment among viewers :)
The problem with the channel at the moment is that it builds on top of previous episodes, I got into it when it was still understandable to me; check out the older videos and go from there.
