Also, quick note: I think you're confusing anti-de Sitter space w/ de Sitter space? de Sitter has positive curvature (i.e. it curves back in on itself) whereas _anti_ de Sitter space has negative curvature.

I've really enjoyed PBS Spacetime - it's a great "more than layman" but "less than physicist" channel. They aren't afraid to show math, and explain hard concepts. Additionally I've found this channel, from Anton Petrov, to be good in a similar vein: https://www.youtube.com/user/whatdamath https://www.youtube.com/user/whatdamath

Oops! Yes, that was just what came to mind when I meant to be referring to non-flat spacetime in general

Love this show. Originally thought the title was a little misleading since it seemed to suggest "Black holes are like a hologram" was news. In fact, according to PBS Spacetime, the observation that black holes acted like holograms (in a very particular sense) was the impetus for the holographic principle in the first place: http://www.youtube.com/watch?v=Ab8JIzckx_M&t=10m20s http://www.youtube.com/watch?v=Ab8JIzckx_M&t=10m20s
