It's a theory. 394 00:39:11,852 --> 00:39:14,938 Like capturing sunlight, it's not meant to be possible. 395 00:39:15,022 --> 00:39:16,607 But you think you found a way? 396 00:39:17,524 --> 00:39:18,775 That Safiya found a way? 397 00:39:19,401 --> 00:39:21,820 I don't know. I don't know. Maybe. 398 00:39:22,487 --> 00:39:24,823 I can't know for sure until I see her thesis. 399 00:39:29,786 --> 00:39:30,871 What else was in the book? 400 00:39:47,763 --> 00:39:49,640 "Cambridge doesn't feel safe anymore." 401 00:39:55,479 --> 00:39:58,649 - "I am surrounded by a kind of…" - …a kind of dark geometry. 402 00:40:00,526 --> 00:40:03,278 - Saf! - Hello! Safiya. 403 00:40:03,362 --> 00:40:05,781 Something that I thought was impossible, 404 00:40:06,698 --> 00:40:08,951 might actually be possible. 405 00:40:15,082 --> 00:40:19,294 If you're reading this, then what I feared most has happened. 406 00:40:22,965 --> 00:40:26,510 And although it's too late for me, you must 407 00:40:26,593 --> 00:40:29,273 - shine a light on what's going on. - "…a light on what's going on." 408 00:40:38,522 --> 00:40:42,109 It's an abstract. It's a summary of her thesis. 409 00:40:42,776 --> 00:40:43,944 And? 410 00:40:44,027 --> 00:40:46,113 And it's the exact same area as mine. 411 00:40:47,865 --> 00:40:49,032 What's this? 412 00:40:55,205 --> 00:40:56,290 Kaplar Institute. 413 00:40:57,165 --> 00:40:59,585 It's a research institute in Cambridge. 414 00:41:00,752 --> 00:41:03,463 They asked me to join, but… 415 00:41:03,964 --> 00:41:05,632 But… Ed, what? 416 00:41:05,716 --> 00:41:07,259 Her work could be there! 417 00:41:08,093 --> 00:41:10,512 I don't want any part of this. 418 00:41:10,596 --> 00:41:12,431 No, Ed. Kaplar could be our key. 419 00:41:13,015 --> 00:41:14,141 Don't you see? 420 00:41:14,224 --> 00:41:16,268 It's the only way we figure all of this out.
