Lets imagine that we are the are the flat landers for a second. We're doing something, the laundry, and we feel an eerie feeling come over us as if we're being watched. No one else in the room, so you shrug it off. Come to find out, our 3D counterparts were actually observing us, unbeknownst to us (aside from that eerie feeling we got). Stay with me! So, while we are on the persons screen or a piece of paper in front of them (this of course assumes 2D existence is possible, just for the example) and they are viewing us, is this at all similar to what this article is talking about? In this scenario, can we label one Ads and one CFT? Another question kind of, but maybe not separate to that, asks if Ads/CFT is a mathematical description of how things project into seemingly completely separate things depending on your perspective? But they're indeed the same. An example of what I mean, so in our 2D existence we notice a pulsing circle, and then in our 3D existence we realize that pulsing circle is actually someone playing with a ball on a string and the pulsing is the ball getting closer to us in more dimensions than can be expressed properly in the 2D view. That's kind of what I mean...so is Ads/CFT description of the same kind of idea as my... admittedly weak example? Lastly, I would like to say that Quanta is fantastic. I don't understand a lot of what is written in their pages sometimes but that's not due to the writing by any stretch. But it makes me think, which is why I still read it anyway! If I'm not mistaken this is the 2nd time in as many days it was featured on the front page, and rightfully so, I think. Anywho, thanks for reading/taking time to respond if you do.
