"This week on Doctor Who, Amy finds herself stuck in the Tardis." "So IjoinedConfidential and hoped to take us out of this world at the Royal Observatory in Greenwich." "Life on other planets could quite possibly exist." "Well, we think it's quite likely 'cause there are so many planets out there." " But it might not be life as we know it." " Excellent." "I actually can't believe that's real." "That's real." "The Kings Arms meet The Rising Sun in a battle of the pub teams." "That's coming up later in the show." "Andit's Craig Owens passing to the Doctor." "Oh, nice footwork!" "Impressive start from the gangling Gallifreyan." "He's still going." "Look at this!" "Best day's filming ever on Doctor Who today." "Not 'cause of JC, but 'cause we're playing football." "Hello Confidential, it's me!" "So following this week's episode, the Doctor was dealing with the time-loop and Amy was stuck in the Tardis in space." "So here I am at the home of time and space, at the Royal Observatory in Greenwich to find out all about time and space and do time-loops even exist?" "And I'm meeting Dr Maggie Aderin-Pocock." " Hello." " Who is a space scientist." " To find out what the time is." " Ooh." "Ah." "So, Maggie, tell us why we're here today." "Well, as you said, Greenwich is the home of time and space." "The space comes from..." "This is an active astronomical site." "We have an actual telescope here, which is educating the public." "And the Astronomer Royal for the UK used to actually live here." "So space and astronomy plays a vital role here." " Yeah." " But time is critical here as well." "Every new day here on planet Earth starts here at the prime meridian." "And what exactly is this meridian line?" "Actually, well, I can do better than that." "I can actually show you the prime meridian." "So step this way." "Ooh!" "So, this is the meridian." "No, no." "This is the prime meridian." "The prime meridian." "I'm so sorry." "Meridians are lines, imaginary lines, that run from the North Pole to the South Pole." "And we use them to actually gauge time." "So the prime meridian is this line here." "And this is effectively the zero, the base line, that we do all other measurements from." "How we're standing at the moment, you're in, I think, the Western Hemisphere and I'm in the Eastern Hemisphere." "So we're having a conversation over hemispheres?" " Across hemispheres, yes." " Okay, so..." "This prime meridian line divides east from west." "So what happens if I do this?" "Ah, now you are in both hemispheres at once." "Look at me, I'm on two hemispheres." "I'm like dancing over hemispheres." "Dancing across the hemispheres." " Yes." "Cool, so essentially, this is the line where time begins?" "It is." "This is where time begins." "Every new day starts along this line." "The thing is it could have been anywhere." "It doesn't have to be Greenwich." "'Cause in the old days, different places had different times." "So for instance, there could be a five minutes' time difference between Bristol and London." "Now, in the old days that didn't matter, but as communication and transportation got better and better, people started realising they had to reset their watches when they went to a different town, which seemed ridiculous." "So what the people across the world came together and said what they want is sort of a universal time." "So as you go across the world, you have a different time." "But you need a baseline to measure it from." "So they debated where they should put the baseline." "And after a long, protracted conversation and a vote, they decided to put it here in Greenwich." "We'll return to the Observatory later as I want to find out more about the science behind the episodes ofDoctor Who." "On set, the cast and crew get ready to shoot what could be the beginning of a beautiful relationship." "And action." "So what's the plan tonight?" "Pizza, booze, telly?" "Yeah, pizza, booze, telly." "What is he doing up there?" " You put the advert up yet?" " Yeah, did it today, paper shop window." ""One furnished room available immediately, shared kitchen, bathroom," ""with 27-year-old male, non-smoker," ""L400 pcm, per calendar month, suit young professional. "" "Pretty much any guy who's single, who has a really, really close female friend who he always says, "We're just friends,"" "the truth is he's probably in love with her and that's no different than with Craig." "That's your mission in life, Craig." "Find me a man." "Yeah, otherwise you'll have to settle for me?" "You'll have to settle for me first." "When you're in that situation, it's quite galling." "When you're looking at it from the outside, it's quite funny." "I love you." "Well, that's good, 'cause I'm your new lodger." "With two time travel machines for Amy to contend with in this week's episode," "I want to know if there really is the possibility of life on other planets." "And who better to ask than a space scientist?" "So here we are in the planetarium in the Royal Observatory." "So I'm still with Maggie, who hopefully has all the answers." "You and the Doctor travel through space time through science fiction, but what I want to do now is I want to take you on a tour of the universe, to show you what's really out there." "This is planet Earth." "This is where we live." "Earth is quite amazing, 'cause as we go through our journey, you'll see that Earth is covered in water." "Four-fifths of the Earth's surface is water." "And about four-fifths of our body is water." "So we're very much a product of the planet we live on." "Now what we've done is we've zoomed into the centre of our solar system." "And here's the Sun." "Got sunspots drifting past there." "Now, the Sun provides us with virtually all the energy we use here on Earth." " So the Sun is the powerhouse." " Okay." "And it keeps all the other planets orbiting." "And here we have the planets of the inner solar system." "Mercury, Venus, Earth and Mars." "Time is definitely sped up here, 'cause it takes Earth a year to go all the way round the Sun." "And here it's actually taking just a few seconds." "So now what we're doing is we're zooming out." "We've got the Sun in the centre." "Now it just looks like a very dim star and we're seeing all the planets in our solar system." "And what we want to do next is we want to go and visit the planet Jupiter." "Now, Jupiter is the largest planet in our solar system." "In fact, you could fit 1,000 Earths into Jupiter." " So it's pretty massive." " Pretty big." "But then again, you could fit 1,000 Jupiters into the Sun." "So that means you could fit a million Earths into the Sun." "So the Sun is pretty huge." "So it is..." "It is completely massive." "Yes." "What we're doing now is we're zooming out to our galaxy, the Milky Way." "And you can see that there is a plethora of stars out there." "We live just on one of the spiral arms, rather boringly." "But it's estimated that in the Milky Way, there are about 150 billion stars." "It's a bit of a mind-boggling number!" "What?" "So life on other planets is quite possible?" "Well, we think it's quite likely, 'cause there are so many planets out there." "But it might not be life as we know it." "Travelling through time isn't the only thing the Doctor seems to be good at." "He's also got a nifty right foot." "Let's just shoot some goals now." "Let's just shoot Matt scoring some goals." "The football match was very easy to do." "In fact, it didn't need a lot of choreography simply because Matt Smith's so brilliant at football." "It could be a volley, then I'll do a..." "comes in on the shirt and I'll go..." "Craig can cross one in and I can finish with my left foot." "Header'd be great." "You can't escape the fact that he's really good at football." "I think he used to play for Leicester." "To play football as the Doctor, who scores all the goals" " and is the quickest and the best..." "Ready for a take, please." "Sort of like all the dreams coming true at once in a way, I suppose." "Hello and welcome to a very special edition of Football Focus." "The Kings Arms broke new ground this week and made history with their signing of the first football Time Lord." "Yes, it's the Doctor." "Great excitement here at Victoria Park." "The Kings Arms unveiling their new stellar signing." "It's the Doctor!" "Hang on to your boots." "This could be out of this world!" "Well, today the Doctor comes and plays for The Kings Arms with his flatmate Craig." "And what a pairing The Kings Arms boast now with Craig Owens in great form!" "The Doctor and Owens, numbers 11 and seven, a pairing made in heaven." "It's not only his debut for The Kings Arms, it's..." "Well, his debut." "Let the game begin!" "With the Doctor making his debut appearance, it's promised to be the pub league match to rival all pub league matches." "The Kings Arms against The Rising Sun." "We can join Steve Wilson pitchside at Victoria Park in Cardiff for highlights of the game." "And this is how they line up." "The Kings Arms has chosen Craig Owens in his regular spot." "This is what we've all been waiting for, though, the Doctor making his debut for the team and a lot resting on his performance today." "And The Rising Sun looking strong with the formation we've seen them use before." "And it's Craig Owens passing to the Doctor." "Oh, nice footwork!" "Impressive start from the gangling Gallifreyan." "He's still going." "Look at this!" "Oh, what a goal by the Doctor!" "It's one-nil to The Kings Arms!" "And he's off again." "Magnificent footwork!" "Oh, and he's made it two!" "He's in magnificent form today." "Oh, what timing by the Doctor!" "But what else would you expect?" "It's three-nil." "Fantastic play by Owens." "Oh, what a turn for a big man!" "Unlucky." "Oh, and the Doctor with a follow-up to make it four." "Great chest-up by the Doctor and that's five!" "It's six!" "Extraordinary!" "Kings Arms, seven." "It's a free kick." "And Craig Owens is ready to dispatch this in the back of The Rising Sun net." "Assessing his angles..." "Oh, but the Doctor arrives!" "And it's eight!" "And Owens isn't happy!" "The Doctor stole his glory and he's hit eight." "What a performance and what a game!" "Owens doesn't look best pleased." "The Kings Arms have a new hero." "It's the Doctor!" "Now I know a little bit about the science behind the science fiction, there's one more treat in store for me at the Observatory." "We have something else for you." "Really?" "'Cause what I'm going to do is introduce you to the Public Astronomer here at the Observatory," "Dr Marek Kukula, and he has a very nice surprise for you." " Then let us go." "Come on." " Perfect." "There's one more treat in store for me at the Observatory, as Marek lets me take a look at the real sky at night with something truly out of this world." "So, Maggie promised you a surprise and here it is." "It's the biggest refracting telescope in the United Kingdom." "How big is it?" "Well, with telescopes the important thing is the size of the lens, and this one here has a lens which is 28 inches across, which is still about as big as you can make them." "So even though this is 120 almost years old, it really was the Hubble Space Telescope of its day." "Wow!" "And so the bigger the lens the more we can see?" "That's right." "The bigger the lens, the more light you can get through and the fainter the objects you can see so the further out you can see into space." "And that's great for doing astronomy, 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!" "Now we can see the sky, so let's move the telescope down." "With the telescope in place," "I'm about to get the chance to see something totally amazing." "I have no idea what it is, but I'm very excited." "Take a look." "Okay." "See what you think." "Oh, my goodness!" "That's real." "I'm actually looking at Saturn right now." "I can see..." "It's really clear!" "I can see sort of like a yellow ball with these rings going round it." "I can't believe it!" "I really can't." "It's kind of like a yellowy colour." " And how many moons does Saturn have?" " It has at least 60 moons." "And then of course it has the rings, which are made of billions of tiny, tiny icy moons all orbiting round the planet." "They're made of billions of bits of ice up to the size of probably about the size of a car down to the size of a tiny pebble." "And they're all independently orbiting around Saturn like billions of tiny moons." " I can't..." " It's a pretty incredible sight." "It really is." "I mean, it just..." "Wow!" "Okay, so I've got one last thing to show you." "Behind me you can see the meridian line in the form of a laser." "Now, 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 and I think it's fair to say that my brain is ready to explode." "It's completely mind-blowing." "You know, probability suggests that there could be life on other planets and potentially, in the future, time travel could actually be possible." "Um, I find it so fascinating." "I guess I've got a vested interest in it 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."
