"Amy finds herself stuck in the TARDIS." "So I join Confidential and hope to take us out of this world at the Royal Observatory in Greenwich." "Life on other planets... could quite possibly exist?" "but it may not be life as we know it." "Excellent." "I actually can't believe that's real." "That's real." "and now the Great Bear himself." "The Doctor adopts the human touch..." "..deals with tricky situations upstairs and downstairs... watches as everybody gets a bit loopy over the time... and proves a bit of a star on the football pitch." "And it's Craig Owens passing to the Doctor." "impressive start from the gangling Gallifreyan." "He's still going." "Look at this." "What a goal by the Doctor!" "that's coming up later in the show." "Best day's filming ever on Doctor Who today." "but because we are playing football." "it's me. to find out all about time and space and do time loops even exist?" "I'm meeting Dr Maggie Aderin-Pocock..." "Hello!" "to find out what the time is." "tell us why we're here today." "Greenwich is the home of time and space." "This is an active astronomical site. and the Astronomer Royal for the UK used to actually live here." "So space and astronomy play a vital role here." "as well." "Every new day here on planet Earth starts here at the Prime Meridian." "And what exactly is this meridian line?" "I can actually show you the Prime Meridian." "So step this way." "this is the meridian?" "I'm very sorry." "and we use them to gauge time. the baseline that we do all other measurements from." "How we're standing at the moment - you're in the western hemisphere and I'm in the eastern hemisphere." "So we're having a conversation over hemispheres?" "Yes." "This Prime Meridian line divides east from west." "So what happens if I do this?" "Now you are in both hemispheres at once." "I'm in two hemispheres!" "I'm like dancing over hemispheres." "Dancing across the hemispheres." "essentially this is the line where time begins." "It is." "This is where time begins." "Every new day starts along this line." "it doesn't have to be Greenwich." "different places had different times - there could be a five-minute time difference between Bristol and London. people had to reset their watches when they went to a different town!" "So people needed a universal time." "but you need a baseline to measure it from." "they decided to put it here in Greenwich." "So this is a hugely important little line." "which means I will be the first person to..." "You'll be the first person to see the new day." "Wow." "We'll return to the observatory later to find out more about the science behind Doctor Who." "the cast and crew get ready to shoot what could be the beginning of a beautiful relationship." "telly." "LOUD BANG What is he doing up there?" "in the paper shop window. suit young professional." "Pretty much any guy who's single who has a really close female friend and that's no different than with Craig." "Craig - find me a man." "otherwise you'll have to settle for me." "first." "I think it's a situation everyone's been in at some point." "but I really should go." "Do you mind if I go?" "you should go." "go." "Because I could stay." "No." "I mean we've got plans..." "Just pizza." "I'm going." "Cool." "Yeah." "I'll see you... soon." "it's out there and it will change their friendship for ever." "just..." "I don't know if you knew... it's quite galling." "it's quite funny." "I love you." "because I'm your new lodger." "wrote a comic strip for Doctor Who Magazine." "The lodger was originally a comic strip in the Doctor Who Magazine." "That is SO an episode." "it's heart-warming..." "It featured David Tennant's Doctor having to stay with Mickey Smith for a week and it was about the sort of domestic arrangements." "because Mickey had left the show and it was no longer possible." "I was fascinated by the idea of the Doctor having to live a normal life." "I think the interesting thing is to actually see him doing it." "It makes it quite a different episode but also quite a fun one." "and ensure that the Doctor doesn't end up it's into the kitchen for the new master chef." "You've got everything I need." "Omelette!" "Oeufs!" "who's the girl on the fridge?" "Sophie." "Girlfriend?" "Friend who's a girl." "There's nothing going on." "works for me." "really?" "how interesting." "That could be handy." "AND the omelette." "though." "The boss has a rubbish business model." "but I'm just a phone drone." "The whole idea was that the Doctor should be quite messy because he obviously doesn't do it very often." "Matt won Junior MasterChef when he was nine... so he's a pretty good cook." "Why am I telling you this?" "I don't even know you." "people never stop blurting out their plans while I'm around." "Where's your stuff?" "it'll materialise." "Ha-ha-ha!" "We can call a pizza." "Cut." "he said." "He really loves it and he wants to do really." "anyway." "so I would take it with a pinch of salt." "But being human doesn't come that naturally to a Time Lord." "Action." "All I've got to do is pass as an ordinary human being." "Simple." "What could possibly go wrong?" "'Have you seen you?" "' isn't it?" "Doctor?" "How long are you going to be in there?" "Ah!" "Oopsie." "Oh dear." "tell me what normal blokes do." "they go down the pub." "but I could." "It is vital that this man upstairs doesn't realise who and what I am." "So no sonic-ing." "No advanced technology." "I can only use this because we're on scramble." "I'm talking absolute gibberish." "Practical eruptin into chicken." "Degas Lombardi spiral." "What are you doing here?" "never worked in anywhere." "I suggest you take your custom elsewhere." "he's called the Doctor." Why not?" "Because it's weird!" "Doctor?" "no. we can sort of see that as well." "he's behaving exactly as a character would do in that situation." "Transferring the comic into a TV script required a few changes." "he needs to get into that house." "He doesn't have that relationship the Doctor had with Mickey in the comic strip." "I didn't put my address." "aren't you lucky I came along?" "More lucky than you know." "We actually needed for Craig to really like him." "your door." "My door." "My place." "My gaff." "Me with a key. whilst simultaneously defeating the the spaceship's deadly autopilot." "and the Doctor solved the technological plot." "let's go." "Why don't we make both stories resolve together in the same way?" "you idiot! I want to know if there really is the possibility of life on other planets." "And who better to ask than a space scientist?" "Here we are in the Planetarium in the Royal Observatory." "who hopefully has all the answers. but I want to take you on a tour of the universe." "This is Planet Earth where we live. four fifths of the Earth's surface is water." "so we're very much a product of the planet we live on." "and at the centre of the screen should be Inverness." "We're in Inverness!" "Brilliant!" "And where are we going from Inverness?" "I think the next stop is the moon." "So I'm going from Inverness to the moon. and also the moon has no atmosphere." "and here's the sun." "We've got a sunspot drifting past. and it keeps all the other planets orbiting." "Earth and Mars." "because it takes Earth a year to go round the sun and here it's just taking a few seconds." "we want to go and visit Mars." "My retirement plan is to go and retire on Mars." "Why would you like to retire to Mars?" "!" "I know that." "but I think I could survive that." "and we need water to live." "That means I could just about live on Mars." "Life could potentially be on Mars?" "but we keep on searching." "OK." "We're zooming out." "We've got the sun in the centre and now we're seeing all the planets in our solar system." "What we want to do next is we want to go and visit the planet Jupiter." "Jupiter is the largest planet in our solar system." "000 Earths into Jupiter." "So it's pretty massive." "Pretty big." "000 Jupiters into the sun." "So that it means you could fit 1 million Earths into the sun." "So the sun is pretty huge." "So it is completely massive." "that's our local star." "Proxima Centauri." "and that is what some people don't realise. and could have planets going round them. and you can see that there is a plethora of stars out there. there are about 150 billion stars." "It's a mind-boggling number!" "What?" "!" "So life on other planets is quite possible?" "because there are so many planets out there." "But it might not be life as we know it." "But now I want to show you what's at the edge of the universe. so a really long exposure." "Then we got the data back and we realised that what we thought was empty space wasn't actually empty at all." "It actually had all these points of light in it there are stars out there." "But then we realised that each one of those points of light is another galaxy." "so that's just..." "That's even more..." "Yes." "..mind-boggling." "we've tried to work out how many galaxies are in and we've come up with a rather larger number." "100 billion galaxies." "that must just be..." "a huge amount that's very difficult to compute." "Yes. 000 years." "the problem is getting out there." "which is why I wish the TARDIS was real." "I want the TARDIS to be real!" "Me too." "Life back on Earth is a little more complicated." "The Doctor offers Craig and Sophie something you'd expect from any good friend - advice." "The Doctor plays Cupid with both of them and finally gets them to realise that what's keeping them there is the fact that they want to be together." "Doctor." "weekend." "And there's six billion people on the planet doing pretty much the same." "I'm starting to wonder where they all come from." "then." "What do you really want to do?" "Part of the Doctor's behaviour in the scene where he inspires Sophie to go away is to inspire her to realise why she's not going." "he can see a mile off they ought to be together." "He says about the keys..." "You unlocked the door." "How did you do that?" "Those are your keys." "but I..." "How do you know these are my keys?" "I've been holding them." "I have got another set." "You've got two sets of keys to someone else's house?" "Yeah." "I see." "She is sort of waiting for Craig to make the first move and he actually seems incapable of doing it." "too." "He's been around the human race for a very long time." "this is like monkeys mating." "What do you really want to do?" "Don't laugh." "I only ever tell Craig about it." "maybe abroad." "I saw this orang-utan sanctuary on telly." "What's stopping you?" "true." "They're quite happy where they are." "didn't take it." "What's wrong with staying here?" "what if they don't love you back?" "secure and just a little bit miserable till the day you drop." "The Doctor knows that's a prompt to her to get something going." "a call centre is about where you should be." "Why are you saying that?" "That's horrible." "Is it true?" "Of course it's not!" "I'm not staying in a call centre all my life." "I can do anything I want. .." "Oh!" "did you see what he just did?" "what's happening?" "Are you going to live with monkeys now?" "Sophie." "Work out what's really keeping you here. and I want to find out how the Doctor and Amy manage to do this." "do we think that time travel is actually possible?" "they think it is." "I'll try and explain why." "This is a baby's rattle." "This represents 3D space." "y and z." "to and fro." "so take 3D space and another fourth dimension - which is time." "OK." "Einstein came up with this idea of space-time." "So we can take the 3D of space and time as well and so this sheet now represents space-time." "and B is our next door neighbour star." "so we want to get to our sun to the next sun?" "Yes." "you'd have to go from A to B in a straight line and that would be the quickest way you could get there. you take A and B and put them together and then form something like a wormhole to travel between them." "much quicker way of getting there than the conventional route from A to B." "That's a very handy short cut." "and we believe that wormholes exist because the mathematics indicates but we haven't found them yet." "So time-travel is actually possible?" "there's one caveat on that." "and paradoxes are nasty." "There's this thing called the grandfather paradox." "don't do that." "of course." "so who's gone back and shot your grandad?" "we don't believe you can travel backwards in time." "but not backwards in time." "that's mind-boggling." "Yes." "Travelling through time isn't the only thing the Doctor seems to be good at." "but he's also got a nifty right foot." "Let's just shoot some goals now." "Let's shoot Matt scoring some goals." "The football match was very easy to do because Matt Smith's so brilliant at football." "A bit of volley." "Comes in on the chest and I do..." "Right." "Header would be great." "you're kind of waiting to play but you never get the ball cos he's just stolen the game." "I'm familiar with that feeling." "So I need James's POV of the Doc scoring as well." "So I'll do it... but we need to do his point of view of Matt just taking over the game." "yeah?" "You can't escape the fact that he's really good at football." "I think he used to play for Leicester." "but it's actually all CGI." "I apologise if I hit anyone." "He can't kick a ball to save his life." "but this is all green screen." "The ball isn't even there." "They've just put it in with a computer so it looks like kneeing it and volleying it." "Saving in the tap-in for the Doc?" "Yeah." "Look." "There's not even a ball there." "This is all CGI." "He's never even seen a ball in his life." "What?" "I'm sure you've all read the stories." "I played Leicester schoolboys." He didn't." "stunts." "Watch this." "Stand by for a take." "Do the computer-generated ball." "so he's brilliant." "really good." "'James is a right laugh and I was just playing football all day.'" "I felt really lucky." "Chest and I'll put it high up." "you chest it and put it higher." "I suppose." "Hello and welcome to a very special edition of Football Focus." "The King's Arms broke new ground this week and made history with their signing of the first football Time Lord." "it's the Doctor." "Great excitement here at Victoria Park." "it's the Doctor." "Hang on to your boots." "This could be out of this world." "the Doctor comes and plays for the King's Arms with" "Craig." "And what a pairing the King's Arms boast now with Craig Owens in great form." "a pairing made in heaven." "But the planet-hopping time-traveller had better beware." "He faces a formidable foe today." "It's the Rising Sun." "And the Doctor happy to muck in for this one." "What a game in store!" "his debut." "Let the game begin." "it's promised to be the Pub League match to rival all Pub League matches." "The King's Arms against the Rising Sun." "We can join Steve Wilson pitch-side at Victoria Park in Cardiff for highlights of the game." "46 cast and crew." "And this is how they line up." "The King's Arms has chosen Craig Owens in his regular spot." "though. and a lot resting on his performance today." "And the Rising Sun looking strong with a formation we've seen them use before." "And it's Craig Owens passing to the Doctor." "nice footwork." "Impressive start from the gangling Gallifreyan." "He's still going." "Look at this." "what a goal by the Doctor!" "It's 1-0 to the King's Arms." "And he's off again." "Magnificent footwork." "And he's made it two!" "He's in magnificent form today." "Nice ball in by the Doctor." "The Rising Sun have barely had a kick yet." "Great excitement on the touchline." "what timing by the Doctor!" "But what else would you expect?" "It's 3-0." "Fantastic play by Owens." "what a turn for a big man." "Unlucky." "The Doctor with a follow-up to make it four." "and that's five." "It's six!" "Extraordinary!" "King's Arms seven." "It's a free-kick." "And Craig Owens is ready to dispatch this in the back of the Rising Sun net." "but the Doctor arrives." "And it's eight!" "And Owens isn't happy." "The Doctor stole his glory and he's hit eight." "and what a game." "Owens doesn't look best pleased." "The King's Arms have a new hero." "It's the Doctor." "and the Football Focus studio." "Let's get some reaction to that." "Lee and Lawro have joined us in the studio." "What do we think?" "An incisive pass there from Craig Owens to the Doctor." "Lawro?" "Nice dummy." "not particularly good." "But look at how much time he's got." "mind." "Loves his step-over." "Just beat the 14 on his way through to the goal." "What a finish as well." "super strike." "that." "we thought the big lad was going to take it." "That was a dodgy free-kick." "Dan." "Absolutely brilliant." "Look at that." "the goalkeeper." "Not so sure." "I think he should have saved that." "definitely." "Now we can hand back to Doctor Who Confidential for some post-match interviews." "Best day's filming ever on Doctor Who today." "but cos we're playing football." "Action." "THEY CHEER please." "but to play today was just bliss." "yeah." "And then he just comes in and takes it. that's why." "It's not me." "It's the..." ""Thank God I've got to be rubbish." "I really scuffed the ball and stuff and I was just really in character." "football." "This is what... best day ever?" "I love this." "Yeah." "but there's another important time-related question I need an answer to." "the Doctor's facing something called time loops." "Do we think those can exist?" "Time loops are probably possible. it's bringing two bits of space-time that shouldn't be together together." "you have a little jump in space and time." "I think in this episode it's a jump in time." "People are dying up there!" "People are dying!" "People are dying!" "These two bits of space-time aren't meant to be linked and yet somehow they have been linked." "It doesn't make sense." "No." "That's what would happen physically?" "you'll have that strange glitch." "So you set up these loops." "but they're loops that don't add up." "And what do we think will actually happen during that?" "things won't make sense." "So there is science behind the scripts." "You sound surprised." "Sorry." "The time loop in the football scene..." "What we wanted was for the Doctor to be able to be in the scene patently cos he's realised it affects Amy in the TARDIS." "We did this with a green screen and put the Doctor in and then he had to act the scene as though everybody was in it." "not ever." "We shot the scene without the Doctor in it but with all all acting as though the Doctor was there." "Then the visual effects team take over and they manage to marry the two and make it so that but Matt in the middle can act normally." "Action." "THEY CHEER" "Amy." "And cut." "Are you guys all right?" "Is the camera all right?" "LAUGHTER" "Good job you put that poly on it." "A time loop in the Doctor's world is a sign of sinister goings-on in the flat above." "and that's when the Doctor realises something very dangerous is happening upstairs." "Action." "Is this..." "A statement on modern society." "ain't modern society awful?" "You've only been here three days." "They've been the three weirdest days of my life." "Your days will get a lot weirder if I go." "'The Doctor is free of the time loop.'" "Time travel." "It can happen sometimes." "everyone is compelled to repeat whatever action they're doing or whatever they're saying." "People are dying up there!" "People are dying!" "People are dying!" "People are dying up there!" "People are dying up there!" "People are dying!" "Amy." "SHE SCREAMS" "They're being killed." "It's happening again right now." "Someone's up there." "dark force." "It's not just a passive thing that you move through." "I love all that." "Action." "Someone's up there." "And there is definitely no time to lose as the alien upstairs has one very important victim." "Craig!" "Someone's dying." "wait." "I've got the plans." "It cannot be upstairs." "It's a one-storey building." "'There is no upstairs!" "'" "What?" "! it's time to see if I can do a little time travelling of my own." "We have something else for you." "Really?" "I'm going to introduce you to the public astronomer here at and he has a very nice surprise for you." "Then let us go." "Perfect." "Come on." "Marek is going to show me a star that has quite a relevance to Doctor Who." "here we are and what we're going to see is this star up here. and the other thing we can do here as well as having no clouds that's what we're bringing up now." "And you can see the lines of the constellation and now the Great Bear himself." "Oh. or Talitha." "which means the light that we're seeing from it now has been travelling towards us for 47 years." "47 years!" "That's right. because it means that the light that we're seeing set out in 1963." "isn't it?" "the year that Doctor Who began. they would just be able to pick up the first television transmissions of" "Doctor Who if they're tuning their receivers towards us at the moment." "guys!" "Brilliant!" "So we're looking at 1963." "You are actually looking at 1963. we can actually show you the past. the further you're looking back into time." "That is incredible and mind-blowing." "We're looking back in time." "looking right back in time." "there are many different stars at many different distances." "you're looking at a different period of history." "So there are stars up there where the light set out 22 years ago when you were being born." "my goodness!" "it's like a bit of a birthday star for you." "cool!" "please." "The realisation of what's upstairs comes as a surprise to the Doctor and Craig." "There's a great deal of space and a definite lack of time." "sort of the climax of the episode realise that this has been on top of Craig's flat the whole time." "Action." "What?" "What?" "The crashed spaceship was a massive set." "And in fact we decided to make it even bigger. in that it's larger on the inside than on the outside." "Action." "What?" "of course." "It was just really exciting and it was like an eight-page scene." "because there were eight pages of dialogue and there were special effects and pyrotechnics with smoke and sparks and we just had to get our heads down and get going." "the time engine IS the flat." "Someone's attempt to build a TARDIS." "you want those moments when you're in a big spaceship." "There's always been an upstairs." "Has there?" "Think about it." "Yes." "You've got to run around and something's at stake." "it's willing her to touch the activator." "it's not going to have her." "What?" "Why's it letting her go?" "The Doctor has realised now that it's zapping people and trying to get them to try and be the pilot." "Because we were on this raised platform in the middle of the set it's like really." "I'm Captain Troy Hansen please state the nature of your emergency." "the crew are dead." "A pilot is required." "You're the emergency crash programme." "You've been luring people here to try them out." "you will help me." "he was doing this whole thing where his body was lurching around." "You'd better" "# Push the button And let me know... #" "The correct pilot has been found." "And we're off." "the whole solar system would burst." "I'm way too much for this ship." "My hand touches that... the whole solar system goes up!" "so he manages to get Craig to touch it instead." "Geronimo!" "Aaargghh!" "that he loves Sophie." "Why don't you want to leave?" "Sophie." "I don't want to leave Sophie." "I can't leave Sophie." "I love Sophie." "Sophie then realises that she loves him." "you idiot!" "They both put their hands on the console of the space ship and the whole thing blows up." "do you mean that?" "Of course I mean it." "Do you mean it?" "do you mean it?" "Yes." "Craig." "The planet's about to burn!" "kiss the girl!" "Kiss the girl!" "Doctor?" "You've done it." "SHE LAUGHS" "You've done it!" "Big yes." "help me." "now." "Out!" "the emotions of it and stuff." "I really enjoyed it." "The whole top floor just vanished." "as Marek lets me take a look with something truly out of this world." "Maggie promised you a surprise and here it is." "It's the biggest refracting telescope in the United Kingdom." "How big is it?" "and this one has a lens which is which is still about as big as you can make them." "it really was the Hubble space telescope of its day." "the more we can see?" "the more light you can get through so the further out you can see into space." "where you want to explore as far out into the universe as you can possibly go." "So let's get the dome open and then we can have a look at the sky." "Let's go." "so let's move the telescope down." "I'm about to get the chance to see something totally amazing." "but I'm very excited." "Take a look and see what you think." "What is it?" "my goodness!" "That's real." "I'm actually looking at Saturn right now." "I can see..." "It's really clear!" "I can see it's sort of like a yellow ball with these rings going round it." "SHE GASPS" "I can't believe it!" "I really can't." "it's just really hard to compute that that's actually out there right now." "It's kind of like a yellowy colour." "And how many moons does Saturn have?" "which are made all orbiting round the planet." "up to the size down to the size of a tiny pebble." "like billions of tiny moons." "I can't..." "It's a pretty incredible sight." "it just..." "Wow!" "That is so incredible and I can see the two moons as well." "# Everybody's starry eyed And everybody knows" "# Everybody's starry eyed And nobody knows... # so I've got one last thing to show you." "you can see the meridian line in the form of a laser." "I've been told on a good night it can stretch for up to 70 kilometres and it runs right through London and into Essex." "So that brings me to the end of our visit to the observatory." "I think it's fair to say that my brain is ready to explode." "probability suggests there time-travel could actually be possible." "I find it so fascinating." "because I've been working on Doctor Who." "But this visit has given me a tiny glimpse into the life of Amy Pond." "Thanks for joining me."
