3 Body Problem: a deep dive into the Netflix show
This episode of Physics World Stories explores the science, politics and ethics in the Netflix series 3 Body Problem. Adapted from the celebrated Chinese novel The Three-Body Problem by Liu Cixin, the multi-layered story centres around humanity’s first contact with an alien civilization. As the drama unfolds, with physicists among its lead protagonists, the plot navigates the challenges of communicating with aliens across interstellar space – and the inevitable tensions that arise on Earth.
To discuss 3 Body Problem, podcast host Andrew Glester is joined by three special guests:
- Matt Kenzie: the series’ science adviser, a particle physicist at the University of Cambridge. Kenzie’s role in informing the show’s scientific elements gives him unparalleled insight into the integration of physics into its narrative.
- Jennifer Ouellette: a renowned science writer who reviewed Cixin’s book The Three-Body Problem for Physics World back in 2015. Ouellette shares her thoughts on the book’s themes, and assesses the merits of the TV adaptation by the creators of Game of Thrones.
- Hannah Little: a linguist at the University of Liverpool who is also a member of the SETI Post-Detection Hub. That initiative, based at the University of St Andrews in Scotland, considers how we should communicate with aliens should we discover we are not alone in the cosmos.

1 00:00:05,005 --> 00:00:06,135 - Physics world. 2 00:00:06,585 --> 00:00:08,975 Hello and welcome to the Physics World Stories podcast. 3 00:00:09,555 --> 00:00:11,415 I'm Andrew Gluster. And in this episode, 4 00:00:11,545 --> 00:00:13,455 we're gonna be exploring the science 5 00:00:13,795 --> 00:00:16,895 behind the Netflix series three Body Problem. 6 00:00:17,435 --> 00:00:20,495 The American Science Fiction Television series is created 7 00:00:20,875 --> 00:00:24,135 by David Benioff, DB Weiss and Alexander Wu, 8 00:00:24,355 --> 00:00:27,415 and it is based on the Hugo Award-winning Chinese novel, 9 00:00:27,715 --> 00:00:30,215 the Three Body Problem by Li Sing, 10 00:00:30,285 --> 00:00:31,815 that if you haven't seen the series, 11 00:00:31,815 --> 00:00:33,815 there will be some minor spoilers. 12 00:00:34,095 --> 00:00:37,055 I do recommend watching the series, so if you want 13 00:00:37,055 --> 00:00:40,175 to go away and watch, maybe you only need to watch the first 14 00:00:40,995 --> 00:00:42,215 two or three episodes 15 00:00:42,215 --> 00:00:44,775 before he can come back to listen to this. 16 00:00:45,185 --> 00:00:46,775 Later in the podcast we'll hear 17 00:00:47,075 --> 00:00:50,135 how scientists in today's world are considering 18 00:00:50,355 --> 00:00:52,335 how we might communicate with aliens. 19 00:00:52,875 --> 00:00:54,935 And we'll hear much more from this man. 20 00:00:55,085 --> 00:00:58,815 Matthew Kenzie, the science advisor for the Netflix series. 21 00:00:59,035 --> 00:01:02,295 The Three Body Problem takes its name from something 22 00:01:02,805 --> 00:01:04,415 from the world of physics 23 00:01:04,875 --> 00:01:07,335 - In the same way that in our solar system, we sort 24 00:01:07,335 --> 00:01:09,655 of have the sun and Jupiter as our two body system, 25 00:01:10,075 --> 00:01:11,415 and then the earth is a third body, 26 00:01:11,415 --> 00:01:13,815 but it doesn't really exert any influence on the sun 27 00:01:13,835 --> 00:01:15,455 or Jupiter 'cause it's too small, 28 00:01:16,045 --> 00:01:17,415 it's not, not massive enough. 29 00:01:17,635 --> 00:01:19,295 Uh, and so it's then just a sort 30 00:01:19,295 --> 00:01:21,695 of a little particle traveling through the, 31 00:01:21,695 --> 00:01:23,895 the gravitational field of the other two bodies. 32 00:01:23,955 --> 00:01:26,855 And so I think that's the, the parallel being drawn in, 33 00:01:27,075 --> 00:01:28,655 in the three body problem is there are, 34 00:01:28,655 --> 00:01:30,935 there are three suns, three stars in this system, 35 00:01:31,435 --> 00:01:34,925 and the planet is then just a little point, uh, that wanders 36 00:01:34,925 --> 00:01:36,685 through their gravitation of field. 37 00:01:37,385 --> 00:01:38,605 Um, but 38 00:01:38,605 --> 00:01:41,485 because there are three bodies, that system is not stable. 39 00:01:41,675 --> 00:01:44,685 It's in a chaotic di dynamic orbit. 40 00:01:45,345 --> 00:01:48,085 Um, so I mean, if we, if we talk about 41 00:01:48,085 --> 00:01:51,485 what the three body problem is generally, um, you know, 42 00:01:51,505 --> 00:01:54,925 it refers to any system in which you have three objects, 43 00:01:55,055 --> 00:01:57,565 three bodies, which are all exerting a significant 44 00:01:57,565 --> 00:01:59,245 gravitational force on each other. 45 00:01:59,945 --> 00:02:03,645 Now, if you have two bodies, um, they have some center 46 00:02:03,705 --> 00:02:06,925 of mass point, so they have some, some minimum, right, 47 00:02:06,925 --> 00:02:08,045 some stable position 48 00:02:08,075 --> 00:02:11,365 because they're then just orating, uh, orbiting 49 00:02:11,365 --> 00:02:12,925 around their, their center of mass. 50 00:02:13,265 --> 00:02:16,045 In the three body states, you don't have 51 00:02:16,275 --> 00:02:17,445 that same stability. 52 00:02:18,265 --> 00:02:21,285 And so you can, you know, write down the forces on all 53 00:02:21,285 --> 00:02:23,325 of these bodies, but then you can't actually solve 54 00:02:23,325 --> 00:02:24,565 their equations of motion. 55 00:02:25,465 --> 00:02:27,405 Um, and what you want to do 56 00:02:27,405 --> 00:02:29,565 as a physicist is write down basically 57 00:02:29,725 --> 00:02:31,005 the equation of motion for things. 58 00:02:31,025 --> 00:02:33,885 It tells you that where they will be, uh, 59 00:02:34,095 --> 00:02:38,645 after a, a given amount of time, um, so you can sort 60 00:02:38,645 --> 00:02:40,365 of simulate that in the three body problem. 61 00:02:41,025 --> 00:02:42,685 Um, you can write these things down, 62 00:02:42,745 --> 00:02:45,205 but you, you generally don't know, uh, 63 00:02:45,255 --> 00:02:47,765 where they will be at some future time 64 00:02:47,765 --> 00:02:50,525 because orbits are chaotic and hard to predict. 65 00:02:51,385 --> 00:02:53,965 Um, so, you know, the, the analogy is like the weather, 66 00:02:54,105 --> 00:02:57,125 that's a many body system, uh, of these kind 67 00:02:57,125 --> 00:02:59,165 of different clouds and structures, kind of 68 00:02:59,165 --> 00:03:00,885 that exerting influence on each other. 69 00:03:01,505 --> 00:03:05,005 Um, but trying to predict their behavior is, uh, 70 00:03:05,005 --> 00:03:07,805 impossible on a, on a sort of particle level 71 00:03:07,905 --> 00:03:09,765 or individual body level. 72 00:03:10,275 --> 00:03:11,725 Yeah. So that, that, that's 73 00:03:11,725 --> 00:03:13,365 what the three body problem refers to. 74 00:03:13,545 --> 00:03:16,685 And that means that this system, you know, is in a, 75 00:03:16,765 --> 00:03:18,125 a kind of chaotic orbit. 76 00:03:18,185 --> 00:03:20,965 And I guess if you run that forever, eventually it will end 77 00:03:20,965 --> 00:03:22,645 with one of the bodies being ejected 78 00:03:23,185 --> 00:03:25,085 or two of those bodies colliding. 79 00:03:25,425 --> 00:03:27,885 And if you live on a planet which is in that system, 80 00:03:27,885 --> 00:03:30,245 that's obviously not very, not very good. 81 00:03:30,345 --> 00:03:32,485 And I, I guess if you're an advanced enough civilization, 82 00:03:32,545 --> 00:03:33,925 you would have to figure out a way 83 00:03:33,925 --> 00:03:35,045 of getting off that planet. 84 00:03:35,805 --> 00:03:37,405 - Jennifer Willett is a science writer 85 00:03:37,865 --> 00:03:40,725 and a staff writer at AZ Technica in the US 86 00:03:41,235 --> 00:03:42,525 several years ago now. 87 00:03:42,665 --> 00:03:44,565 She wrote a review of the books 88 00:03:44,785 --> 00:03:47,485 of the Three Body Problem four Physics World, 89 00:03:47,625 --> 00:03:49,525 and has now watched the series on Netflix. 90 00:03:49,825 --> 00:03:51,085 - The guys who did Game of Thrones, 91 00:03:51,085 --> 00:03:52,565 David Benioff and David Weiss. 92 00:03:52,705 --> 00:03:54,165 You know, were adapting it. 93 00:03:54,265 --> 00:03:57,405 And so I, I know people got very upset at the finale, 94 00:03:57,405 --> 00:03:59,045 the last couple seasons of Game of Thrones, 95 00:03:59,045 --> 00:04:01,125 and you know, there's some legit criticisms there. 96 00:04:01,505 --> 00:04:04,205 But what the Davids are good at is taking a really 97 00:04:04,525 --> 00:04:07,845 sprawling, complex novel with multi-layers and adapting it. 98 00:04:07,845 --> 00:04:09,405 And especially those big powerful, 99 00:04:10,025 --> 00:04:11,885 you know, showcase scenes. 100 00:04:11,885 --> 00:04:13,645 They're wonderful at bringing those to life. 101 00:04:13,705 --> 00:04:16,285 And I thought all of that was very, very evident, uh, 102 00:04:16,345 --> 00:04:17,525 in this, um, 103 00:04:17,645 --> 00:04:19,965 I thought it was generally a very, very good adaptation. 104 00:04:20,435 --> 00:04:22,405 It's a different medium, so you're not going 105 00:04:22,405 --> 00:04:24,885 to get the same depth you're going 106 00:04:24,885 --> 00:04:26,445 to get in a novel, and I don't expect that. 107 00:04:26,945 --> 00:04:29,325 But I thought as terms of just sheer entertainment goes, 108 00:04:29,405 --> 00:04:31,325 I thought that the, uh, the show was fantastic. 109 00:04:31,505 --> 00:04:33,285 It was really, really well done.

679 00:28:21,495 --> 00:28:24,235 And so they, they either have one input, one output, 680 00:28:24,255 --> 00:28:25,795 or two inputs and one output, 681 00:28:26,375 --> 00:28:28,795 and they're making up the little semit transistors 682 00:28:28,795 --> 00:28:31,355 that are in our, uh, modern day computers. 683 00:28:32,505 --> 00:28:36,445 And so, yeah, it doesn't have to be particularly advanced 684 00:28:36,505 --> 00:28:39,245 or powerful, I suppose, the computer to run this simulation, 685 00:28:39,825 --> 00:28:41,525 uh, depending on how accurately 686 00:28:41,525 --> 00:28:43,645 and how, uh, quickly, you know, how, 687 00:28:43,785 --> 00:28:45,565 how long you want it to predict for. 688 00:28:46,665 --> 00:28:49,205 Um, I think the difficulty is trying 689 00:28:49,205 --> 00:28:50,765 to run an operating system on 690 00:28:50,765 --> 00:28:53,085 that in which you can run your code. 691 00:28:53,785 --> 00:28:55,645 And then, you know, 692 00:28:55,645 --> 00:28:58,285 there's also this other big dependence in a real circuit, 693 00:28:58,525 --> 00:28:59,925 I guess on the clock frequency. 694 00:29:00,345 --> 00:29:02,805 People need to know when they are zeros 695 00:29:02,805 --> 00:29:03,845 and when they are ones, 696 00:29:03,845 --> 00:29:05,925 you somehow need someone banging out a rhythm 697 00:29:06,465 --> 00:29:07,965 to keep them in sync. 698 00:29:07,965 --> 00:29:10,285 Otherwise, different bits of your circuit will go out 699 00:29:10,285 --> 00:29:11,285 of sync with the others 700 00:29:11,545 --> 00:29:14,405 and you'll have these horrible kind of problems. 701 00:29:15,145 --> 00:29:19,325 So you need enough people to do it in time if one 702 00:29:19,325 --> 00:29:20,525 of them makes a mistake. 703 00:29:21,365 --> 00:29:23,845 I think basically your program crashes. 704 00:29:24,515 --> 00:29:26,405 It's a sort of control alt, delete situation, 705 00:29:26,425 --> 00:29:29,965 but you would somehow need to know to unravel that 706 00:29:30,035 --> 00:29:32,765 because your prediction will, will make, will be nonsense 707 00:29:32,945 --> 00:29:34,645 or your, your signal will get stuck. 708 00:29:35,705 --> 00:29:38,405 But yeah, I think it could be doable if you had enough 709 00:29:38,405 --> 00:29:40,405 people doing it in clock. 710 00:29:40,465 --> 00:29:43,005 And of course it's a game again. 711 00:29:43,105 --> 00:29:45,645 So the characters who are playing, you know, the real people 712 00:29:45,705 --> 00:29:47,925 who are playing these characters, uh, 713 00:29:48,065 --> 00:29:51,285 in the game have convinced this leader to get all 714 00:29:51,285 --> 00:29:52,685 of his armies of people together 715 00:29:53,185 --> 00:29:55,805 and maybe, you know, whoever's in control of the game 716 00:29:56,435 --> 00:29:58,205 sets the parameters such that, you know, 717 00:29:58,755 --> 00:30:01,405 your human beings do act like a computer. 718 00:30:01,625 --> 00:30:04,605 The, the problem is, is your simulation is only, uh, 719 00:30:04,605 --> 00:30:06,165 gonna last for some amount of time. 720 00:30:06,365 --> 00:30:09,085 I mean, you know, that bit is possible, 721 00:30:09,205 --> 00:30:11,205 I think making the computer running this code, 722 00:30:11,745 --> 00:30:14,725 but then you still can't, it still can't work really, 723 00:30:14,725 --> 00:30:18,605 because you have to know the exact starting conditions 724 00:30:18,605 --> 00:30:21,125 of your three body system to run this simulation. 725 00:30:21,665 --> 00:30:23,365 And your simulation is numerical. 726 00:30:23,475 --> 00:30:26,725 It's not, uh, it's not a perfect solution to this problem. 727 00:30:27,225 --> 00:30:29,765 So it will walk over time away from 728 00:30:29,765 --> 00:30:31,645 where the real outcome goes. 729 00:30:32,145 --> 00:30:34,285 And so, yeah, you have to measure the exact positions 730 00:30:34,285 --> 00:30:37,245 of these three sons and their exact ve philosophies, 731 00:30:37,745 --> 00:30:40,725 and then put those as the starting input to your program 732 00:30:41,185 --> 00:30:42,565 and then run the simulation. 733 00:30:42,905 --> 00:30:44,965 And then in real life, what you were doing, you would try 734 00:30:44,965 --> 00:30:46,685 and have a live feedback loop, right? 735 00:30:46,685 --> 00:30:48,485 That observed where these bodies were going 736 00:30:48,945 --> 00:30:51,725 to then run this back through your simulation again to try 737 00:30:51,725 --> 00:30:54,205 and somehow minimize the difference between 738 00:30:54,205 --> 00:30:56,685 what you are predicting and, and what you are observing, 739 00:30:56,865 --> 00:30:59,285 and then seeing where that goes in the future. 740 00:31:00,065 --> 00:31:02,845 You know? So it's like some kind of Hawkeye, uh, 741 00:31:03,065 --> 00:31:04,445 but uh, you know, that's 742 00:31:04,445 --> 00:31:06,285 what you wanna run on this computer, right? 743 00:31:06,705 --> 00:31:09,245 So you know where your planet's gonna be tomorrow in, 744 00:31:09,305 --> 00:31:10,445 in a month, and so on. 745 00:31:10,665 --> 00:31:12,285 - The one other thing that sort of 746 00:31:13,765 --> 00:31:16,325 confused me slightly was using the sun 747 00:31:16,465 --> 00:31:17,885 as an amplifier of the message. 748 00:31:17,985 --> 00:31:19,045 Is that feasible? 749 00:31:19,385 --> 00:31:21,845 - The kind of way that I thought about this, 750 00:31:21,865 --> 00:31:24,245 and this is, this is mentioned a bit in the book as well, 751 00:31:24,265 --> 00:31:26,645 is yeah, the amplifications of signals, right? 752 00:31:26,705 --> 00:31:28,885 So I mean, the sun has, has layers 753 00:31:28,905 --> 00:31:31,645 and it has these convection currents, right? 754 00:31:31,665 --> 00:31:32,805 In its different layers. 755 00:31:33,465 --> 00:31:36,365 And so you could certainly imagine that for some frequencies 756 00:31:36,365 --> 00:31:38,125 of radiation, you know, 757 00:31:38,375 --> 00:31:40,645 every time they cross a boundary basically, 758 00:31:40,645 --> 00:31:44,325 where there's a different makeup of the, the, the plasma 759 00:31:44,475 --> 00:31:47,005 that makes up the sun, um, you know, 760 00:31:47,005 --> 00:31:48,525 there's a transition probability 761 00:31:48,585 --> 00:31:49,925 and a reflection probability. 762 00:31:50,075 --> 00:31:51,445 They are, they are a wave. 763 00:31:51,585 --> 00:31:54,205 And so some of it will reflect off the surface, some 764 00:31:54,205 --> 00:31:55,605 of it will be transmitted. 765 00:31:56,485 --> 00:31:59,385 And then if you have another layer behind that of, you know, 766 00:31:59,485 --> 00:32:02,065 the right number of wavelengths, if you reflect off 767 00:32:02,065 --> 00:32:04,785 that layer, then the two can interfere, uh, 768 00:32:04,785 --> 00:32:06,065 and they can interfere constructively. 769 00:32:06,805 --> 00:32:10,545 And so whether the actual structure 770 00:32:10,605 --> 00:32:12,585 of the sun is symmetric enough 771 00:32:12,725 --> 00:32:15,945 and the wavelength of the, of the radiation has to be, 772 00:32:15,965 --> 00:32:17,385 you know, perfectly tuned somehow. 773 00:32:17,525 --> 00:32:19,545 And that might not be then practical for 774 00:32:19,975 --> 00:32:22,025 what signals you can produce and so on. 775 00:32:22,485 --> 00:32:25,785 But that was kind of the, the principle of the idea that, 776 00:32:25,805 --> 00:32:28,305 you know, just like, like traveling through a bubble, 777 00:32:28,545 --> 00:32:31,665 I guess you get some kind of, uh, interference pattern 778 00:32:31,925 --> 00:32:33,385 and that could be constructive. 779 00:32:33,385 --> 00:32:36,385 And that's exactly how an amplifier then, then works. 780 00:32:37,505 --> 00:32:40,685 I mean, it was kind of, I was gonna say there was, you know, 781 00:32:40,995 --> 00:32:44,845 part of the, the advising role, um, was a bit of time 782 00:32:44,845 --> 00:32:46,925 with the, the cast, what they were. 783 00:32:47,105 --> 00:32:49,445 Uh, and they, they did this, what they were going, 784 00:32:49,445 --> 00:32:51,365 doing the script read throughs, which happened 785 00:32:51,365 --> 00:32:52,805 through sort of three or four day period. 786 00:32:53,665 --> 00:32:55,565 Um, and I was on the set at the time 787 00:32:55,665 --> 00:32:57,125 and met some of the cast then 788 00:32:57,265 --> 00:32:59,285 and had different conversations with different members 789 00:32:59,285 --> 00:33:01,725 of the cast about various different aspects of the show. 790 00:33:02,385 --> 00:33:06,165 But the character that plays the young, um, uh, 791 00:33:06,675 --> 00:33:09,645 when Jay in the, in these early scenes, you know, 792 00:33:09,645 --> 00:33:11,965 the character that transmits this signal, um, 793 00:33:12,185 --> 00:33:14,925 she was very <laugh>, very, um, kind 794 00:33:14,925 --> 00:33:17,365 of interested in this exact, uh, principle 795 00:33:17,385 --> 00:33:19,605 and about how this amplification could occur. 796 00:33:20,145 --> 00:33:23,045 And I think, you know, I eventually convinced her that, 797 00:33:23,105 --> 00:33:25,365 you know, an amplifier, you know, the, 798 00:33:25,425 --> 00:33:29,045 the headphones in your, um, ears can amplify a signal. 799 00:33:29,265 --> 00:33:31,605 So in principle, so could the sun, 800 00:33:31,665 --> 00:33:35,405 but, uh, yes, the, it's not a phenomena 801 00:33:35,405 --> 00:33:36,965 that's been observed as far as I'm aware. 802 00:33:37,195 --> 00:33:38,725 -

There's also maths. 1169 00:49:59,095 --> 00:50:00,645 Maths seems like it would be universal. 1170 00:50:00,645 --> 00:50:02,245 - Yeah. And maths is quite iconic. 1171 00:50:02,465 --> 00:50:06,925 So when we wanna, um, kind of send the number one 1172 00:50:07,385 --> 00:50:08,765 and the number two and the number three, 1173 00:50:09,055 --> 00:50:11,205 there is a direct like correlation 1174 00:50:11,205 --> 00:50:13,445 between the signals and what they mean. 1175 00:50:14,345 --> 00:50:17,885 Um, so maths is a very iconic medium. Yeah. 1176 00:50:17,905 --> 00:50:20,405 And the good thing about maths is it's all about trying 1177 00:50:20,405 --> 00:50:22,285 to work out common knowledge with the aliens. 1178 00:50:22,285 --> 00:50:23,765 So what is it that they already know? 1179 00:50:24,185 --> 00:50:26,565 And if they're an advanced species with, 1180 00:50:26,565 --> 00:50:28,565 with advanced technology, they're likely 1181 00:50:28,705 --> 00:50:30,165 to have nailed maths. 1182 00:50:30,865 --> 00:50:33,565 And so we can send them things like in contact. 1183 00:50:33,805 --> 00:50:35,365 I think it's the frequency of hydrogen 1184 00:50:35,385 --> 00:50:38,165 and hydrogen's the most abundant chemical element in the 1185 00:50:38,365 --> 00:50:41,325 universe, which is why it's a really good kind of foundation 1186 00:50:41,325 --> 00:50:43,765 to say, we know about hydrogen, this is hydrogen. 1187 00:50:44,145 --> 00:50:46,365 Do you wanna chat or other the kind 1188 00:50:46,365 --> 00:50:48,685 of universal contestants like pie or, 1189 00:50:48,685 --> 00:50:51,445 or certain frequencies like the fon sequence. 1190 00:50:51,905 --> 00:50:55,125 - It feels like to me the best way that we've got 1191 00:50:55,125 --> 00:50:56,605 of exploring this stuff is probably 1192 00:50:56,605 --> 00:50:57,925 through science fiction, right? 1193 00:50:57,925 --> 00:50:59,445 Yeah. There's, I mean, we've already talked about 1194 00:50:59,445 --> 00:51:01,285 independence day contact. 1195 00:51:01,995 --> 00:51:04,365 There's arrival, there's three body 1196 00:51:04,365 --> 00:51:05,365 - Problems. 1197 00:51:05,365 --> 00:51:06,885 And quite a lot of the people in the post detection club are 1198 00:51:06,885 --> 00:51:07,965 science fiction authors 1199 00:51:07,965 --> 00:51:10,645 because these, they are necessarily the people who've 1200 00:51:10,675 --> 00:51:13,485 thought about these problems way more than, 1201 00:51:13,515 --> 00:51:14,725 than even scientists 1202 00:51:14,725 --> 00:51:17,165 because scientists are often distracted 1203 00:51:17,185 --> 00:51:20,325 by problems on earth, uh, before they, they start worrying. 1204 00:51:20,345 --> 00:51:22,325 But problems in artist space, 1205 00:51:22,545 --> 00:51:24,885 - Dr. Hannah Little is currently writing a book 1206 00:51:25,755 --> 00:51:28,285 exploring communication with aliens 1207 00:51:28,315 --> 00:51:30,245 through the lens of science fiction. 1208 00:51:30,825 --> 00:51:32,245 You can't get that just yet. 1209 00:51:32,545 --> 00:51:34,245 I'd like to thank Hannah, Jennifer, 1210 00:51:34,705 --> 00:51:36,765 and Matt for talking to me for this episode. 1211 00:51:37,065 --> 00:51:39,365 And I'd like to thank you very much for listening 1212 00:51:39,505 --> 00:51:41,805 and next month we'll be hearing about something else from 1213 00:51:41,805 --> 00:51:42,925 this wonderful world of physics 1214 00:51:43,625 --> 00:51:47,925 and we might just have a new jingle for the podcast 1215 00:51:53,155 --> 00:51:54,245 - Physics world.
