Binge watching it from past to recent videos helps much. Physics is complex, and explaining it without references to a prior knowledge is not possible in a single 20min video, even for Matt. They could do a complete layman format in every video, but that bullshit is already in abundance on yt, and it only solidifies misconceptions and the lack of understanding. You are the target audience, but it is more like a real learning curve than a weekly entertainment. You have to begin from the beginning.

My own impression of SpaceTime is that they are consistent and chronological. I wouldn’t understand that math on my own nor make any inferences, but conceptually everything is pretty clear to me.
