1 00:00:00,100 --> 00:00:01,434 Jacob Pinter: This one is from a few years ago. 2 00:00:01,434 --> 00:00:04,838 This one's a little bit older, but also from Jeremy Schnittman. 3 00:00:05,772 --> 00:00:07,374 Ron Gamble: Yeah, I know, I know. 4 00:00:07,374 --> 00:00:09,642 I know Jeremy's work when I see it. 5 00:00:09,642 --> 00:00:12,245 So this is actually one that I use in my, my talks a lot. 6 00:00:12,245 --> 00:00:13,847 Jacob: Yeah? 7 00:00:14,481 --> 00:00:18,351 Ron: But it gives you a visualization of both kind of edge-on 8 00:00:18,351 --> 00:00:22,522 and top-down of what the accretion disk looks like around a black hole. 9 00:00:23,023 --> 00:00:23,423 Right. 10 00:00:23,423 --> 00:00:27,327 So we're looking at something that kind of looks like a spacetime hurricane, if you will. 11 00:00:27,327 --> 00:00:29,295 Jacob: Wow. Ron: To give you kind of like a natural example. 12 00:00:29,295 --> 00:00:29,996 Jacob: Yeah, yeah, yeah. 13 00:00:29,996 --> 00:00:33,833 Ron: But also you can kind of see where the lensing is kind of up top. 14 00:00:33,833 --> 00:00:36,936 This piece ... again, you're seeing behind the black hole. 15 00:00:37,470 --> 00:00:41,307 So the disk that is ... the part of the disk that's behind the black hole 16 00:00:41,307 --> 00:00:43,076 gets lensed in front. 17 00:00:43,076 --> 00:00:46,579 And so that's how you see that kind of crest up top for the black hole 18 00:00:46,579 --> 00:00:49,849 and you kind of see it kind of spin back around and it goes back up top. 19 00:00:50,116 --> 00:00:52,485 And that's exactly what we see here. Thanks, Jeremy. 20 00:00:52,685 --> 00:00:55,055 for putting this together because I use it a lot. 21 00:00:56,122 --> 00:00:59,125 But yeah, that is, that's what we're seeing. 22 00:00:59,292 --> 00:01:01,761 And it's a very good visualization, both top-down 23 00:01:01,761 --> 00:01:04,931 again and edge-on to see what ... you can see 24 00:01:04,931 --> 00:01:07,067 the spherical surface of a black hole. 25 00:01:07,067 --> 00:01:08,201 Jacob:Yeah, Ron: It’s not a funnel 26 00:01:08,201 --> 00:01:08,935 Jacob:Yeah, 27 00:01:08,935 --> 00:01:11,071 Ron: As we can see, right? [Jacob laughs] 28 00:01:11,071 --> 00:01:14,541 Jacob: I always appreciate hearing a scientist say ‘that movie did a good job’ 29 00:01:14,574 --> 00:01:17,043 because I know that it's not always the case. 30 00:01:17,043 --> 00:01:18,611 Ron: Right. 31 00:01:19,813 --> 00:01:21,381 [NASA]
