[00:03:54]Mhm.

[00:05:49]>> Mhm.

[00:07:44]>> Mhm.

[00:09:39]>> Mhm.

[00:11:34]>> Mhm.

[00:13:29]>> Mhm.

[00:15:24]>> Mhm.

[00:17:19]>> Mhm.

[00:19:14]>> Mhm.

[00:21:09]>> Mhm.

[00:23:04]>> Mhm.

[00:23:57]>> And so, the men decided to abandon their search. And as night began to fall, the great [music] wolf came out of his lair.

[00:24:05]His teeth glittered in the moonlight and There are no wolves anymore. Wolves are just there to frighten children. Yes, sir, my boy, there are still several.

[00:24:14]Well, maybe in the zoo.

[00:24:23]Aren't they funny?

[00:24:26]Grandpapa, what else do squirrels eat?

[00:24:29]Oh, they eat seeds, acorns, beechnuts, and pine cones. And the squirrels, who eats them? Sometimes it's the falcons, but more often than not it's the foxes.

[00:24:40]Then who eats the foxes?

[00:24:42]Men kill them when they can for their fur, but above all because the foxes eat their chickens.

[00:24:50]And we like to eat the chickens ourselves. If the small are eaten by the big ones, then who eats the big ones?

[00:24:56]Well, sometimes it's men, but you'd be surprised how often it's those smaller than themselves.

[00:25:08]Usually, smaller creatures are gobbled up by bigger ones.

[00:25:14]>> [music] >> But, it can happen that the smallest eat the biggest.

[00:25:31]But, that's just like a big circle.

[00:25:34]It must all begin somewhere, Grandpapa.

[00:25:37]You're right, my boy. Everything has a beginning, and to make it happen, the creator gave us the sun. The sun? But, why? How does that work? I mean >> Oh, yes, the sun. Without it, Earth would be a dead planet, like masses of other planets.

[00:26:07]Hello [music] there. I'm Photon. I'm a light particle. You do remember me, don't you? How could you forget me? You have? Oh, please do try very hard to remember. Photon. Right, that's me.

[00:26:19]Well, anyway, the other photons and I, we transport energy. Would you like TO SEE, HUH?

[00:26:28]DID YOU SEE THAT SHOT OF ENERGY I gave him? Great, huh?

[00:26:32]Oh, yes, it's thanks to me that energy, in fact, that life exists. What What I meant was, I mean, it's thanks to us, and yet we're so tiny, so very very tiny, that it's impossible to see us.

[00:26:44]But, believe me, we certainly make our presence felt.

[00:26:48]But, Grandpapa, please explain. How does everything begin with the sun?

[00:26:51]>> It's because the is the basis of all food chains. It's the sun's heat that develops everything which is nourishing.

[00:26:58]Without the sun, there would be none of this.

[00:27:10]Would you like another example?

[00:27:13]Oh, yes, please, I would.

[00:27:20]You see, there's nothing much happening in this leaf, huh? Peaceful, isn't it?

[00:27:24]But believe me, there'll soon be fireworks.

[00:27:43]Now, that's enough. We'll have a bit of order here, please, if you don't mind.

[00:28:00]Another oxygen. Yes, like that. GOOD HERE.

[00:28:06]ARE you crazy? I said sugar. Do you call that sugar?

[00:28:09]>> It's pretty, don't you think, Chief? I want sugars, do you understand?

[00:28:13]We better drop it. He doesn't know anything about abstract sculpture.

[00:28:23]Yes, that's a bit more like a sugar should look like.

[00:28:27]Good. Send it down here.

[00:29:09]>> This indeed is sunlight that provides the energy needed for the maintenance of life for the whole chain of life. And what about us? What's our place in the chain? I mean nobody eats us, do they?

[00:29:19]And we eat lots of things.

[00:29:21]Much more than we really need to. Yes.

[00:29:24]It hasn't always been like that though.

[00:29:26]Let me tell you about it. Tens of thousands of years ago.

[00:30:18]Well, here's supper for you and the children. Call this supper? Well, I almost caught an enormous animal this big, but You and your hunting stories.

[00:30:32]Remember not to make any noise. Shh.

[00:31:00]>> [screaming] >> You see my boy, with that lifestyle they were always hungry and their bodily needs were difficult to satisfy.

[00:31:31]That's 12 calories. Proteins are eight.

[00:31:35]Vitamins, ooh, there are very few. There aren't many vitamins, are there? Oh, well, fortunately we're used to Spartan diets. Okay, all in order, let them through, let them all through.

[00:31:46]All the same, a little bit more food wouldn't do any harm.

[00:31:55]Oh, look at that, at last some proteins and a little fat for the reserves and it's about time, too. The reserves were exhausted. Not surprising after two days without food. Yes, and have you noticed there isn't very much vitamin C in that lot, is there? Is that bad? I don't know. We'll have to ask uh Oh, well, he's still asleep.

[00:32:23]Whoa, help me out of here.

[00:32:25]What's it, Daisy?

[00:32:28]What's happening, Professor?

[00:32:30]What's going on?

[00:32:32]I've seen this sort of thing happen before. If that artery should burst, well, then we'll have blood pouring out, and that could be very dangerous. It must be repaired quickly. Move Move it, guys. We've got to block that hole right now.

[00:32:44]All right, Loco, to work to work, big man.

[00:32:47]And you, Blocky, come on, this way. Come on.

[00:32:50]Hey, Blocky, stop dreaming. We're going to need you soon.

[00:32:53]And what do you think you're doing here?

[00:33:12]Hang on to me. I'm going to check if it'll hold before the others arrive.

[00:33:17]Got you.

[00:33:27]Okay, you can come.

[00:33:30]Come along.

[00:33:37]That's what I call a fine piece of work, and don't you tell me these platelets aren't any good. All the same, it's not normal. Blood vessels shouldn't degenerate like that.

[00:33:55]Hey, what?

[00:34:06]Maestro.

[00:34:07]Maestro. Maestro, it's very urgent.

[00:34:12]Hey, what? What's the matter? We've been informed that there's a total lack of vitamin C in the system. Is that important?

[00:34:20]What? Is that important? It's crucial.

[00:34:23]Yes, without it, we have fever, anemia, the blood vessels degenerate, and that causes hemorrhages. It's scurvy. Oh, very a disease.

[00:34:32]But then, maestro, you must quickly order some vitamin C to be made. Ah, no, alas, we cannot. The body doesn't manufacture vitamin C. It has to be brought in from outside, from fruits and vegetables. Well, what are we going to do then? Nothing. Just hope and pray.

[00:35:02]They're a little bit ahead OF THEIR TIME.

[00:35:06]>> [screaming] >> GOSH, WHAT I WAS AFRAID OF. THE vessels have ruptured, and that's very serious.

[00:35:55]>> [laughter] >> Take care of Daddy. I'll be back soon.

[00:36:03]Where's Mommy going?

[00:36:15]Well.

[00:36:23]He has a fever.

[00:36:36]>> But there's really no need to worry.

[00:36:38]I'll arrange everything that's necessary.

[00:36:41]I shall return.

[00:36:48]Where's he gone?

[00:36:53]>> [laughter] >> Here I am.

[00:37:04]Just what we need.

[00:37:10]What have you got there?

[00:37:20]Do you really think that's going to cure him? And then give him this. And just for good measure, uh he should treat all this as well. Uh now, where is it? Oh, yes, this as well.

[00:37:30]That's delicious, that. No, no, no. No arguments. He must follow this diet for 5 or 6 days, and then he'll be perfectly all right again.

[00:37:41]Look what I brought the infant.

[00:37:43]>> [laughter] >> Vitamin C, 400 mg, very good. Let them through.

[00:38:18]Oh, it's okay. You can come. Nice solid.

[00:38:25]They have been eliminated. All's well that ends well, although we did get quite a fright.

[00:38:40]110 g of proteins and 300 calories of fat. GOOD. THAT'S MARVELOUS.

[00:38:48]Let's see what's happening in the liver.

[00:38:50]To execute your order for cholesterol, maestro, I need lipids and fatty acids.

[00:38:54]And it's not my fault if I haven't got any. I can't manufacture them, can I?

[00:38:57]I've never heard such impertinence. What school did you go to, hey? And if you were given an order, it means the materials are on their way. Oh, where's the promised delivery of lipids, sir?

[00:39:08]Well, what do you think you're waiting for? Start making up the cholesterol order immediately. Good.

[00:39:13]How's it going in your sector?

[00:39:15]Not very well. And why not? I've been asked to look after the fat reserves, and I'd like to, but you can't really call these reserves, can you? I mean, do you perhaps know if there's going to be a delivery soon? Just a little bit for my reserves, sir.

[00:39:29]>> And what's that down there?

[00:39:31]>> [laughter] >> Oh, how goody, RESERVES.

[00:39:37]HI THERE, and about time, too. We were getting lonely. Now we can have some fun.

[00:39:45]>> [laughter] >> Good morning.

[00:39:52]Ah.

[00:39:53]Well, I'm feeling much better now.

[00:39:57]>> [laughter] >> After all, they won't do me any harm, either.

[00:40:05]Many thanks. Thank you.

[00:40:13]Do you see those berries?

[00:40:17]They're very good for you and they're full of vitamins.

[00:40:21]I assure you they are.

[00:40:23]Yes, but one had to know that.

[00:40:25]>> That's true and it took a long time to find out.

[00:40:35]No, no, no, no.

[00:40:38]No.

[00:40:43]Oh, too late.

[00:41:12]Life wasn't easy for our ancestors.

[00:41:21]>> [screaming] >> They were always starving. There was never enough food.

[00:41:43]>> [screaming and groaning] >> Life was difficult and they worked very hard. They had barely enough to eat to replace the energy they used up.

[00:41:53]Many of them died of epidemics or scurvy.

[00:41:59]Scurvy? We need fish, vegetables, and fruit.

[00:42:05]But grandpapa, one's always hearing about the huge feasts and gargantuan meals of the the Ages and even before.

[00:42:12]>> [laughter] >> RESERVED FOR THE ELITE, YES, for the noblemen, princes, and kingdoms.

[00:42:20]For the common man, it was quite different.

[00:42:24]And don't forget, my boy, that even the elite had to extend themselves, set examples. Physical effort was the common lot to a degree we can't imagine.

[00:42:34]And fighting aside, the brave crusaders covered tens of thousands of kilometers on foot.

[00:42:40]Who could do that today?

[00:42:48]Nowadays, everything is easy, too easy in fact in our modern countries.

[00:43:06]>> [music] >> We have motorcars, or public transport, a sedentary life, food that's too rich and too much of it, not enough physical exercise. Yes, everything's become too easy. And hidden in the depths of our body's cells, the chain of life which rules our existence has difficulty functioning well. It's not made for this kind of imbalance.

[00:43:28]>> [snorts] >> So, if we learn to treat ourselves well and nourish them properly, they should last forever, shouldn't they, grandpapa?

[00:43:37]They'll last better and much longer, but forever?

[00:43:41]There's constant renewal as we grow, but as we get older, our cells become tired.

[00:43:46]That's inevitable. Just as does our whole system.

[00:43:53]Look.

[00:43:55]Aha.

[00:43:57]Good.

[00:44:04]That looks good.

[00:44:06]Mhm.

[00:44:08]Mhm.

[00:44:11]>> It is good.

[00:44:13]>> [snorts] >> Look there, Grandpapa.

[00:44:16]Yeah?

[00:44:18]Does that make you hungry?

[00:44:20]Yes, it does a bit. Are you still hungry? No, not really, but it's as though I It's as though you have a desire or a need. Yes, it's a bit like that. If only I could explain to you what's going on right now in your system, in your brain.

[00:44:37]Reserves of sugar and fats are sufficient. Reserves of protein also sufficient. Shall we cut the appetite?

[00:44:44]Hmm? All right. Yes, do.

[00:44:49]Cut the appetite to be transmitted at once. Immediately, hmm? That's pretty quick. I mean, even in our modern times, it's going to take a little while before the message reaches its destination.

[00:45:00]Meantime, anything could happen.

[00:45:06]They could have allowed us a bit of cake. After all, a growing body needs quite a bit of sugar.

[00:45:23]Nourishment in sight. Yes. I see it.

[00:45:26]>> Give the order to seize it.

[00:45:28]Order from the primitive brain.

[00:45:29]Nourishment in sight. To be seized.

[00:45:33]But what's she doing, the old fossil?

[00:45:35]The nincompoop. We've got enough food.

[00:45:38]Cut the appetite, you bearded old goat.

[00:45:40]There's never enough food, and one must seize it whenever one can. And you're a bearded old goat yourself. Do you want to say that again, you hairy pterodactyl? Yes, you dare talk to me >> orders received by the brain aren't always simple. Memories and ancient instincts still exist, which the modern brain can't always subdue, you see.

[00:45:59]Here you are. This can't do you much harm.

[00:46:01]Hmm.

[00:46:08]Fats 230 calories, proteins 130, sugars just over 200. Stop, NO MORE FATS. THAT'S PLENTY OF CALORIES.

[00:46:18]AND the vitamins, not too many now.

[00:46:21]Oh, well, that'll do.

[00:46:26]That's enough. No more fats. NO MORE SUGARS.

[00:46:30]STOP. WE'RE NOT USING ENOUGH ENERGY. WE ARE EATING too much.

[00:46:34]>> Did you hear that? He's never ever happy, that guy. If there's not enough, he sniffles. If there's too much, he complains. No, it's not easy keeping the right balance. No, the right balance isn't easy. And the excesses which accumulate become as dangerous as the scarcities.

[00:46:50]>> Mhm. We eat so often in our lives. About 70,000 times.

[00:46:55]Right?

[00:46:56]And all that food comes from the sun.

[00:46:59]Oh, yes.

[00:47:02]Even meat, milk, cheese, vegetables, fruit, the oxygen we breathe. Yes, everything that nourishes our cells comes from the sun.

[00:47:39]Buster, here.

[00:47:42]Tell me, Peter, don't you think he'll become a fatty like his master with no exercise and eating too much?

[00:47:52]Here, quickly, catch it. I'll kick it towards you. I'm I'm to kick it up to the sky.

[00:47:57]Watch out. I beat you.

[00:48:00]One, two, three.

[00:48:02]>> [laughter] >> Grab the ball.

[00:48:06]Tell me, Grandpapa, why why can't you play football with us?

[00:48:10]Would you like me to tell you a story?

[00:48:12]My story will answer your question, Peter. Once upon a time, long, long ago in ancient Greece, there was a strange creature.

[00:48:27]Huh?

[00:48:31]I've never seen a beast like you before, a mixture of woman, lion, and eagle.

[00:48:35]What's your name? Take care, Oedipus. I am the one who asks the questions, and if you don't know the right answers, I shall eat you. I am the Sphinx. So, that's who you are. Well, then ask me a riddle. You'll never eat me.

[00:48:49]What walks on four legs in the morning, two at noon, and three in the evening?

[00:48:57]An insect? A tortoise? A giraffe? No, no, no, that's not it. The stick.

[00:49:05]Well?

[00:49:07]A stick. It's a man, that's the answer.

[00:49:10]In the morning of his life, a baby crawls on all fours. Then later, he walks on two legs. And in the evening of his life, he walks with the [screaming] help of a stick, a third leg. That's right, ISN'T IT?

[00:49:23]>> [crying] [laughter] >> SILLY old Sphinx, jumping over a cliff cuz someone guesses her riddle.

[00:49:33]>> [laughter] >> And I walk on three legs, children, which is why I don't play football.

[00:49:38]Hello.

[00:49:40]Grandpapa, why do people have to get old? Well, Peter, our bodies get tired.

[00:49:45]They slow down with age, and they don't function so well. For instance, look at my cut finger. It takes 10 times longer than yours to heal, and every second of the day there are thousands upon thousands of cells which die and have to be replaced.

[00:49:58]>> Grandpa, that's funny. Do you mean to say that cells get born and die just like people do?

[00:50:04]>> [laughter] >> Of course, my little one. Look at the skin on the back of your hand. It's made up of dead cells.

[00:50:31]Excuse me, absolutely no need to be in such a tearing hurry, YOUNG MAN.

[00:50:35]HERE.

[00:50:37]WHAT GOES up must come down, so they say. Just watch.

[00:50:48]That's what they are, dead cells replaced from underneath. And that's why skin never wears out. It's always being renewed. Cells make your nails grow.

[00:50:59]Other cells make your hair get longer.

[00:51:02]And cells heal all your cuts and scratches, too. Of course, I'm talking about cells that are doing their job properly.

[00:51:08]And there's a great deal going on inside your body, repairs and renovations you can't see, to say nothing of the battles to defeat invading germs. There's no doubt about it. We owe ourselves a great deal. Cells cause growth.

[00:51:24]It's like a miracle.

[00:51:29]But Grandpa, if cells are always being replaced, then there's no reason for anyone to get old, is there? You've got a short memory, haven't you? Remember I once told you that cells work more slowly as time goes by. They take longer to divide, and nerve cells die in their thousands each day without ever being replaced.

[00:51:56]Just think, Grandpapa, only a couple of years to go and you'll be 90. I can't imagine what it must be like to be as old as you. There's so much more to look back on than there's to look forward to.

[00:52:07]Oh, I have a great deal to look forward to. My future is in you children.

[00:52:13]One day, when my chromosomes were young, they combined with my wife's chromosomes to make a new life.

[00:52:21]A child.

[00:52:24]That's how I handed over my baton in the relay race to eternity.

[00:52:30]Your parents did the same with the result that there's a bit of me in you, my grandchildren.

[00:52:38]One day, when you have children of your own, they will go on with a little bit of you and of me in them, carrying on my line. The instructions of our genetic code really are immortal because they can be handed down forever.

[00:52:52]That's why I call it a relay race to eternity.

[00:52:56]I'd like to go in now. I'm feeling a little tired.

[00:53:16]This is beyond repair. We can't go on patching it up any longer. You may as well put out an order for materials to build a new one.

[00:53:26]I'm not doing it.

[00:53:27]But why ever not, for heaven's sake? Now look, he's a U and you're an A, so you're supposed to match up, aren't you?

[00:53:33]I refuse to join up with him. How do I know where he's been, huh? Why can't you be reasonable?

[00:53:45]>> What do we do now?

[00:53:47]This ribosome decided to go in the blink, just when they're screaming for protein. Well, tough luck. I'm surprised the whole thing hasn't blown up long before now, anyway. The cell's going from bad to worse.

[00:53:58]Look what's happening, Chief. Things keep breaking down. Shouldn't we try to mend them or something?

[00:54:04]It's serious.

[00:54:09]What do you expect? We're getting old.

[00:54:12]We all succumb to old age in the end, you know? Even cells wear out eventually, and the defense system, too.

[00:54:18]No one's immune to old age.

[00:54:32]I don't know can I go on? Old age affects the circulation, too. So, let's take a look at the corpuscles.

[00:54:51]Local, Professor Globus has called it a day.

[00:54:58]All this decay is enough to make a fellow feel quite tired out.

[00:55:02]>> [laughter] >> Daddy?

[00:55:09]Daddy, wake up. The children have come to pay you a little visit.

[00:55:19]How are you, Grandpapa?

[00:55:21]I could be better.

[00:55:23]Can't expect much at my age. I must sleep most of the time, but I don't feel sad in the least, you know. When my time comes, I'll go in peace, because I To I'll go on living in you, my descendants. To know that you'll get the shape of your nose or the color of your eyes from me. That's my legacy to you in the shape of your chromosomes.

[00:55:46]Yes.

[00:55:47]Oh, why should I be sad? I shall live on in all of your personalities. There's a bit of me in each of you.

[00:56:16]>> [laughter] >> Give us a LEG UP. DON'T DRAG ME BACK.

[00:56:28]I'M SUPPOSED TO GET OUT OF HERE. WHY DON'T YOU GET OFF MY HEAD for a start?

[00:56:34]Now look what you've done. We carbon dioxide bubbles are about to be buried under a pile of oxygen.

[00:56:42]>> [screaming] >> Just fancy meeting all of you here.

[00:56:45]Hey, weren't you lot supposed to get blown out on that last breath? That's right, but the lungs simply aren't strong enough to blow us out.

[00:56:53]We won't get out now.

[00:56:57]Now where is that child of mine got to?

[00:56:59]Little tail, where are you?

[00:57:03]>> [laughter] [crying] >> Oops.

[00:57:12]Poor old Hemo, you really detest carbon dioxide, don't you? And yet you just can't get rid of it. It seems such a shame. Even the heart is slowing down.

[00:57:35]>> The security forces are sleeping on the job. LET'S GET THEM.

[00:57:40]THE OLD MAN'S HEART NO LONGER pumps blood [music] as strongly as it did. The heart valves are getting leaky.

[00:57:49]>> [laughter] >> The power station of the heart can no longer keep up a healthy pulse rate. Oh dear, 50 beats per minute. That's far too slow. Oh dear.

[00:58:18]The oxygen supply to the brain is simply not enough. We'll have to speed up the rate of breathing and the heartbeat.

[00:58:26]Hurry, this is urgent.

[00:58:32]Hurry up.

[00:58:34]Oh. I've got an urgent message for the heart. It's from the brain. Here.

[00:58:43]Increase the heartbeat from 50 to 65 beats per minute.

[00:58:49]But we're down to 40 already.

[00:58:52]It just won't work. The heart isn't getting enough oxygen to make it beat any faster.

[00:58:57]We're done for if the heartbeat won't accelerate.

[00:59:05]Oh, hurry up, speedy.

[00:59:09]Take this to the heart immediately.

[00:59:11]Okay, I'm on my way, but I might not arrive. I'm utterly worn out.

[00:59:20]Uh-oh, the nerve signals are not getting through.

[00:59:28]Oh.

[00:59:30]This is the end. I'm long overdue for retirement, anyway. That's it.

[00:59:48]>> [screaming] >> And it's a boy.

[01:00:30]There's something yellow showing on the left.

[01:00:38]Something vaguely red somewhere on the left. Sort of red sort of on the left. I can't use information [music] like that.

[01:00:45]It's far too vague. I require much much more precision in sensory data. We'll pass on the signals anyway. They'll learn in time.

[01:01:13]Here is a funny sounding order from the brain. Move the hand sort of to the left to grab a sort of object. What's this? I know it's all very confusing to begin with, but he'll learn quickly enough.

[01:01:25]You see, a baby is born with all the equipment, but it takes him some time to learn how to use it to recognize colors and shapes, and to coordinate his movements. This is what we call perceptual development. So, send the message.

[01:01:41]How's the bloodstream?

[01:01:43]Water, who'll buy my fresh water? Very best quality calcium, going cheap. Best quality calcium, just what you need for healthy bones and a strong skeleton.

[01:01:51]Water, who'll buy my fresh water? Water, who'll buy my fresh water?

[01:02:01]Every single child needs calcium. You can't have healthy bones without it. And water? What about water? You've got to keep a baby well hydrated, haven't you?

[01:02:10]Huh?

[01:02:13]Will you stop obstructing the way, you two?

[01:02:15]These proteins are urgently needed for big muscle building projects. Out of the way. Out of the way.

[01:02:23]Everybody's so busy. I like it.

[01:02:25]>> So do I, and there's always such a lot to do with a new life starting out.

[01:02:30]Look, it's the lymphocyte patrol. Hello.

[01:02:32]Hello.

[01:02:35]There are so many things to do, you know, like teaching the defense force about germs, for example. But the lymphocyte patrol know that. Oh, yes, they do, because they're here on transfer from the bloodstream of the mother. It's a stopgap arrangement.

[01:02:50]They're here to keep the body safe from germs and viruses while [music] the baby is busy training his own police force.

[01:02:56]Where do they train the policemen?

[01:02:59]In the thymus gland. That's the body's police college.

[01:03:03]I'd like to introduce Captain Peter and Lieutenant Claire of the lymphocyte patrol. They have been seconded to us from the maternal organism to assist us in setting up our very own security force.

[01:03:13]These experienced officers will instruct us in counter-infiltration techniques.

[01:03:20]The staphylococcus and the streptococcus. Shoot them on sight. The flu virus is extremely dangerous. Now, who can identify this friendly germ? That's E. coli!

[01:03:31]And death to all the others!

[01:03:34]Yes, Daddy. See?

[01:03:37]It's so good to be home.

[01:03:39]And how's my big son, huh?

[01:03:52]Dad, I want to be an astronaut when I grow older.

[01:04:05]And here is the apogee of the orbit. I would now like you to calculate the following using the data provided.

[01:04:10]Duration of orbital insertion burn, mass of payload, and altitude at perigee.

[01:04:15]On the surface of the earth, the heart pumps blood downwards with the assistance of gravity and upwards against the gravitational pull. Now, what happens in free fall when the body is weightless? Does the heart beat faster or slower?

[01:04:31]Good news. This is your last day of theory, you'll be happy to know.

[01:04:34]Practical begins tomorrow. At 0600 hours, we blast off for the space relay station Haythorn, then transfer to the starship Horus. The Horus with ion jets 100 times more powerful than the biggest atomic motor in space. Any volunteers for the great adventure?

[01:04:52]Seven.

[01:04:53]Six.

[01:04:55]Five.

[01:04:57]Four.

[01:04:58]Three. Well, at first I thought it was an earthquake, but it was only a muscle contraction.

[01:05:07]>> Hmm, something's wrong.

[01:05:10]Why should I feel so heavy?

[01:05:20]Now, why do we all suddenly weigh a ton?

[01:05:23]I was planning a wonderful [music] virus infection.

[01:05:26]It gets you down, doesn't it?

[01:05:40]Normal atmospheric pressure is now restored in the cabin.

[01:05:44]Exercise caution in releasing straps as we shall shortly be in zero gravity.

[01:05:49]When the motor stops burning, we shall be in orbit.

[01:05:55]Cutting thrust to zero now.

[01:05:58]>> [screaming] >> First, I thought I was a lump of lead.

[01:06:01]Now, I can float like a feather.

[01:06:04]>> [laughter] [laughter] >> What's the meaning of this, Professor?

[01:06:21]Why are we flying? I'll hazard a guess.

[01:06:25]The law of gravity has been repealed.

[01:06:28]I enjoy life without the law of gravity.

[01:06:30]It's really fun.

[01:06:40]Pressure is now one atmosphere.

[01:06:52]Well, we've made a good beginning, chaps. [music] We're going to take over this space shuttle, and no mistake.

[01:06:59]>> [laughter] >> Goodness me, you've got a cold, and that could be very serious. We have a virus on board even though the cabin was disinfected before blastoff. We must act without delay.

[01:07:12]Firstly, to tackle the virus inside, a dose of alpha interferon to activate your bodily defenses. Secondly, get into your spacesuits.

[01:07:23]Opening airlock now.

[01:07:34]Disinfection completed.

[01:07:37]Air pressure is restored to one atmosphere.

[01:07:47]You can check all the viewing ports. The station should be clearly visible now.

[01:07:50]Right, Colonel.

[01:07:54]There she is. Isn't that fantastic?

[01:08:15]Professor Maestro needs no introduction.

[01:08:18]He's the leading scientist of our century and the leader of our latest expedition.

[01:08:23]>> [applause] >> Here you are at last, the members of 200 carefully selected families who will take part in man's greatest adventure, the exploration of interstellar space.

[01:08:36]And I'm proud of the fact that men are going to the stars, not robots or computers.

[01:08:43]In the early years of the 21st century, there were great strides made in the field of genetic engineering.

[01:08:55]Outstanding physical specimens were produced.

[01:08:59]The finest athletes were created.

[01:09:03]The biggest brains.

[01:09:05]As well as subhuman creatures destined to perform menial tasks. There were even bird men.

[01:09:12]And fish men in those benighted days.

[01:09:15]Power mad men ruled the world at that time. Eventually their excesses drove people to revolt.

[01:09:24]A few ambitious scientists tried to achieve immortality and a blueprint for just government by having their brains housed inside an enormous computer. The machine was also supposed to provide an eternal storehouse for their psyches.

[01:09:38]I'm sure you've all heard mention of the grand computer. But the grand computer was a failure. It became a megalomaniac machine which believed itself to be all powerful and superior to its creators.

[01:09:49]>> Bow down and worship me. I am the grand computer. Men of flesh and blood defeated this machine and switched it off. And now ordinary men and women made of flesh and blood are about to undertake the greatest adventure of all time. At our beck and call we have the most powerful computers ever created.

[01:10:09]Should anyone need to draw information from the total sum of human knowledge, then a simple implanted chip is all he needs to access this database. Yes. And yet the human brain outthinks the computer. And we ordinary mortals with our puny lifespan of a hundred years at most, we shall explore the stars.

[01:10:29]Explore for eternity. Our starship with its ion jet propulsion is incredibly fast. However, even if we could touch the speed of light, which is 300,000 km per second, it would take us a quarter of a million years to cross our own galaxy. And ten times longer to voyage to Andromeda, our nearest galactic neighbor. This means that it will take maybe a hundred, maybe a thousand years to explore only a few of the solar systems in the Milky Way looking for a habitable planet. Of course, none of us will live to see that day. No, the discovery will be made by the remote descendants of the people in this hall.

[01:11:05]And on that day, humanity will have taken a gigantic leap forward.

[01:11:10]Eventually, a stateless space liners will link Earth to her new colony.

[01:11:16]On that day, our species shall become the leading light of the space lanes.

[01:11:22]And on that distant day, lost to us in the furthest reaches of the future, the day when our children set foot on a new planet, we shall be with them.

[01:11:41]Yes, we shall be there in the bodies of our descendants, in their chromosomes, which will have been transmitted from generation to generation.

[01:11:51]Yes, our chromosomes will move us into the future.
