The Science of Doctor Who

00:00:00 Blowing your mind, that's what Doctor Who's all about.

00:02:05 Although it doesn't look pretty from the outside

00:04:03 I'm fine, fine. It's just...

00:05:53 We've already demonstrated the basic physics in the laboratory.

00:07:42 I would love it if one day we could have a TARDIS

00:09:35 but at the same time, sometimes we can consider distorting space-time.

00:11:31 And the difficulty comes if you start travelling backwards in time.

00:13:16 Believe me... it was an accident.

00:14:50 is if this were a parallel universe.

00:17:03 Watching Doctor Who regenerate from cells

00:18:51 Repeat: Prisoner Zero will vacate the human residence

00:20:25 My colleague Stephen Hawking has stated that

00:22:24 They're usually not very happy. They're usually very angry.

00:24:07 and creating more Cybermen.

00:26:08 There is something about the Daleks that is inherently evil.

00:27:48 And so we already have senses that can be augmented by implants.

00:29:44 We actually take brain cells-- These are living brain cells

00:31:28 And in a situation like that, how will the world be divided?

00:33:29 which has moving parts and looks just like it, and is in my drawer right now.

00:35:43 There was an episode in a school, where I think the creatures

00:37:41 I wouldn't like there to be two of me. What if the other one's better?

00:39:20 They actually come together out of goo.

00:40:59 At the present time, we have not been able to clone a primate

00:42:41 But it's almost parallel to what's going on nowadays.
