1 00:00:00,000 --> 00:00:02,802 So this is actually one that I use in my, my talks a lot. 2 00:00:02,802 --> 00:00:04,004 Jacob: Yeah? 3 00:00:04,004 --> 00:00:07,874 Ron: that gives you a visualization of both kind of edge-on 4 00:00:07,874 --> 00:00:12,045 and top-down of what the accretion disk looks like around a black hole. 5 00:00:12,045 --> 00:00:12,545 Right? 6 00:00:12,746 --> 00:00:16,383 So we're looking at something that kind of looks like a spacetime hurricane, if you will. 7 00:00:16,383 --> 00:00:18,918 Jacob: Wow. Ron: To give you kind of like a natural example. 8 00:00:18,918 --> 00:00:19,619 Jacob: Yeah, yeah, yeah. 9 00:00:19,619 --> 00:00:23,456 Ron: But also you can kind of see where the lensing is kind of up top. 10 00:00:23,456 --> 00:00:26,559 This piece ... again, you're seeing behind the black hole. 11 00:00:26,559 --> 00:00:30,397 So the disk that is ... the part of the disk that's behind the black hole 12 00:00:30,397 --> 00:00:32,165 gets lensed in front. 13 00:00:32,165 --> 00:00:35,668 And so that's how you see that kind of crest up top for the black hole 14 00:00:35,668 --> 00:00:38,938 and you kind of see it kind of spin back around and it goes back up top. 15 00:00:38,938 --> 00:00:41,941 But yeah, that is, that's what we're seeing. 16 00:00:41,975 --> 00:00:44,444 And it's a very good visualization, both top-down 17 00:00:44,444 --> 00:00:47,614 again and edge-on to see what ... you can see 18 00:00:47,614 --> 00:00:49,749 the spherical surface of a black hole. 19 00:00:49,749 --> 00:00:50,884 Jacob:Yeah, Ron: It’s not a funnel 20 00:00:50,884 --> 00:00:51,618 Jacob:Yeah, 21 00:00:51,618 --> 00:00:53,753 Ron: As we can see, right?
