Cosmic Voyage IMAX HD

  • 0:00 - 0:03
    Equipped with his five senses
  • 0:03 - 0:06
    man explores the universe around him
  • 0:06 - 0:08
    and calls the adventure Science.
  • 1:09 - 1:12
    Things around us
    aren't always what they seem.
  • 1:29 - 1:33
    ln the everyday world,
    we use a simple scale, ourselves
  • 1:34 - 1:36
    to know what's small and what's large.
  • 1:47 - 1:50
    But what about the worlds that lie beyond?
  • 1:52 - 1:56
    What is truly large and truly small?
  • 2:04 - 2:07
    To explore, to observe
  • 2:08 - 2:11
    to understand the wider world
    we call the universe:
  • 2:12 - 2:15
    This is one of the great human adventures.
  • 2:30 - 2:35
    As we look out at the distant horizon,
    we may ask ourselves
  • 2:36 - 2:39
    what is our true place in the universe?
  • 2:43 - 2:45
    We are all travelers
  • 2:45 - 2:48
    on an unending voyage of discovery.
  • 3:28 - 3:32
    More than 25 centuries ago,
    among the Greek lslands
  • 3:32 - 3:36
    here at the vibrant crossroads of Africa,
    Asia and Europe
  • 3:37 - 3:41
    philosophers devised rational theories
    about the world around them.
  • 3:45 - 3:48
    The wondrous waves and foams
    of nature, they said
  • 3:48 - 3:50
    could be understood.
  • 4:20 - 4:25
    One Greek thinker suggested
    that the Earth moved around the sun.
  • 4:29 - 4:33
    Another taught that everything,
    the work of man and nature
  • 4:33 - 4:37
    was made of particles too small to see.
  • 4:41 - 4:44
    Others estimated the sizes
    of the Earth and the moon
  • 4:44 - 4:48
    and the distances between them,
    and reasoned
  • 4:48 - 4:49
    both were spheres.
  • 4:52 - 4:57
    But it would be centuries before we had
    the tools to extend our vision
  • 4:57 - 5:00
    and confirm the wisdom
    of these early thinkers.
  • 5:02 - 5:03
    ln the meantime
  • 5:04 - 5:08
    people around the world
    gazed on the stars and gave them names.
  • 5:09 - 5:13
    Most assumed the Earth was the center
    of an unchanging universe.
  • 5:48 - 5:50
    Two thousand years passed
  • 5:50 - 5:54
    before a revolutionary breakthrough
    was made by a mathematics professor
  • 5:54 - 5:57
    in the ancient,
    maritime republic of Venice.
  • 5:58 - 6:02
    ln 1609, Galileo Galilei
  • 6:02 - 6:06
    demonstrated an instrument
    that would soon be called a telescope.
  • 6:10 - 6:12
    From the tallest bell towers
  • 6:12 - 6:15
    he showed the device
    could spot approaching ships
  • 6:15 - 6:18
    hours before their sails were visible
    to the naked eye.
  • 6:20 - 6:23
    Later, when he aimed his telescope
    at the night sky
  • 6:23 - 6:27
    Galileo discovered that the moon
    was a world of mountains.
  • 6:27 - 6:29
    Jupiter had its own moons
  • 6:29 - 6:33
    and the Milky Way
    was a band of countless stars.
  • 6:38 - 6:41
    Our own cosmic voyage begins here
  • 6:41 - 6:45
    in the center of Galileo's Venice,
    St. Mark's Square.
  • 6:51 - 6:54
    Since the universe is a big place,
    we could easily get lost
  • 6:55 - 6:59
    so we'll need signposts
    to give us a sense of scale.
  • 7:02 - 7:05
    The acrobats' ring is one meter wide.
  • 7:08 - 7:12
    The crowd is ten times wider,
    ten meters across.
  • 7:12 - 7:14
    Larger by one power of ten.
  • 7:19 - 7:22
    Now, with every step, every ring
  • 7:22 - 7:25
    we travel ten times farther from Venice
  • 7:25 - 7:29
    and our view of the universe
    is ten times wider.
  • 7:32 - 7:35
    The 100-meter ring surrounds St. Mark's
  • 7:35 - 7:39
    and 1,000 meters, one kilometer,
    the city's center.
  • 7:42 - 7:46
    As our speed increases,
    four steps, four powers of ten
  • 7:46 - 7:51
    reveal all the islands of Venice,
    the Adriatic Sea and Northern ltaly.
  • 7:59 - 8:03
    Six steps take in Europe
    from Germany across to the Balkans.
  • 8:08 - 8:10
    And soon, we can see the entire planet.
  • 8:11 - 8:13
    Our home in space.
  • 8:25 - 8:27
    Eight steps on our outward journey
  • 8:27 - 8:31
    eight powers of ten, and we pass
    the farthest reaches of human travel:
  • 8:33 - 8:34
    The moon.
  • 9:00 - 9:03
    lf we visualize the paths
    that the nine planets take
  • 9:03 - 9:05
    in their orbits around the sun
  • 9:06 - 9:09
    at 13 steps from St. Mark's Square
  • 9:10 - 9:13
    the entire solar system comes into view.
  • 9:23 - 9:27
    And with 15 steps, 15 powers of ten
  • 9:27 - 9:31
    we can see our sun is just another star.
  • 9:31 - 9:35
    From here on,
    our voyage will be measured in light-years.
  • 9:36 - 9:39
    The distance light travels in an entire year.
  • 9:41 - 9:45
    Only now do we fly past
    our nearest neighbor stars
  • 9:46 - 9:48
    almost five light-years away.
  • 9:50 - 9:53
    The same journey at the speed
    of today's spacecraft
  • 9:53 - 9:57
    would last 100,000 years.
  • 10:04 - 10:06
    As we cross the perpetual night
  • 10:06 - 10:10
    our voyage takes us up and out
    of our sun's neighborhood
  • 10:10 - 10:13
    near the edge
    of a great pinwheel of stars.
  • 10:36 - 10:38
    The Milky Way is actually a spiral galaxy
  • 10:39 - 10:43
    and our own sun is just one
    of a hundred billion stars in it.
  • 10:45 - 10:48
    At this immense scale, 23 powers of ten
  • 10:49 - 10:51
    each shining light we see is not a star
  • 10:52 - 10:56
    but an entire galaxy
    composed of countless stars.
  • 10:58 - 11:02
    Astronomers have discovered
    galaxies are flying away from one another.
  • 11:03 - 11:05
    The universe is expanding.
  • 11:07 - 11:10
    Our own galaxy, and all the others
  • 11:10 - 11:14
    form clusters and superclusters
    of stupendous size
  • 11:14 - 11:17
    hundreds of millions
    of light-years across.
  • 11:20 - 11:24
    And here, about 15 billion light-years
    from Venice
  • 11:25 - 11:28
    we approach the outer limits
    of the visible universe.
  • 11:29 - 11:34
    What lies beyond this cosmic horizon,
    we cannot see
  • 11:35 - 11:37
    and do not know.
  • 11:53 - 11:57
    While Galileo's telescope
    allowed us to take an outward voyage
  • 11:57 - 12:00
    another innovation,
    here in the Dutch town of Delft
  • 12:01 - 12:04
    would lead us on an inward journey
    of discovery.
  • 12:15 - 12:16
    Over three centuries ago
  • 12:16 - 12:20
    Anton van Leeuwenhoek
    perfected the early microscope
  • 12:20 - 12:24
    and used it to study droplets
    from the waterways of Holland.
  • 12:42 - 12:44
    Come on, over here.
  • 12:48 - 12:50
    As students today
    make their own discoveries
  • 12:50 - 12:53
    imagine the moment
    when van Leeuwenhoek
  • 12:53 - 12:55
    peered through
    his more powerful instrument
  • 12:55 - 13:00
    and discovered a living kingdom
    in a drop of water.
  • 13:08 - 13:11
    This busy world of single-cell paramecia
  • 13:11 - 13:13
    is only one millimeter across.
  • 13:14 - 13:17
    Three powers of ten smaller than a meter.
  • 13:21 - 13:26
    The microscope allows us to continue
    our journey to the realm of the very small.
  • 13:27 - 13:29
    As we move into the cell nucleus
  • 13:30 - 13:33
    each new ring now reveals a world
  • 13:33 - 13:36
    ten times smaller in diameter
    than the last.
  • 13:40 - 13:42
    Deep within the nucleus
  • 13:42 - 13:45
    we come upon
    truly remarkable constructions.
  • 13:46 - 13:49
    Long, spiraling molecules of DNA.
  • 13:52 - 13:54
    DNA holds the chemical codes
  • 13:54 - 13:57
    for the reproduction of most organisms
    on the planet.
  • 13:58 - 14:02
    Whether they're paramecia,
    people or petunias.
  • 14:09 - 14:12
    Voyaging on, we see that molecules
  • 14:12 - 14:15
    are made of even smaller parts
    called atoms.
  • 14:21 - 14:24
    The tiny world of the common atom
    is very strange indeed.
  • 14:25 - 14:29
    lts six electrons seem to swarm
    everywhere at once.
  • 14:33 - 14:35
    Now our voyage takes us through a void
  • 14:35 - 14:38
    that appears as vast as the space
    between the stars.
  • 14:40 - 14:42
    Ahead lies the atomic nucleus.
  • 14:43 - 14:45
    So fantastically small
  • 14:45 - 14:48
    that if the whole atom
    were the size of this theater
  • 14:48 - 14:51
    its nucleus would be like a speck of dust.
  • 14:53 - 14:56
    Yet the nucleus contains
    almost all of the atom's mass
  • 14:57 - 14:59
    packed into particles called protons
  • 15:00 - 15:01
    and neutrons.
  • 15:03 - 15:08
    And these, in turn, are made of smaller,
    more mysterious things called quarks.
  • 15:12 - 15:13
    Exploring this
  • 15:13 - 15:15
    the inner frontier of the universe
  • 15:15 - 15:18
    physicists wonder
    if quarks might contain
  • 15:18 - 15:21
    even tinier building blocks of matter.
  • 15:28 - 15:33
    Scientists are investigating this mystery
    in an underground tunnel near Chicago
  • 15:34 - 15:37
    home of the giant
    Fermilab particle accelerator
  • 15:38 - 15:43
    designed to create conditions
    like those after the birth of our universe.
  • 15:47 - 15:50
    Millions of protons and antiprotons
  • 15:50 - 15:52
    race through these pipes
    in opposite directions
  • 15:52 - 15:57
    nearly at the speed of light.
    A kind of subatomic demolition derby.
  • 16:26 - 16:30
    Now our cosmic voyage
    enters another dimension
  • 16:31 - 16:33
    the dimension of time
  • 16:34 - 16:36
    where knowledge is much less certain.
  • 16:37 - 16:40
    Studying traces of quarks
    from these collisions
  • 16:40 - 16:44
    physicists try to learn
    what our universe was like when it began
  • 16:44 - 16:47
    after the explosion
    known as the Big Bang.
  • 16:50 - 16:52
    One of them outlines the theory.
  • 16:53 - 16:55
    Welcome to Fermilab.
  • 16:55 - 16:58
    Today, astronomers
    see the universe expanding.
  • 16:58 - 17:00
    lmagine running the expansion backwards.
  • 17:01 - 17:02
    Billions of years ago
  • 17:02 - 17:05
    everything must've been packed together
    at enormous density.
  • 17:06 - 17:07
    lt seems incredible
  • 17:07 - 17:09
    but we think that the matter
  • 17:09 - 17:12
    making up everything we see
    in the universe
  • 17:12 - 17:16
    the buildings, trees, people, planets
  • 17:17 - 17:19
    stars out to the most distant galaxies
  • 17:20 - 17:24
    was once crammed together
    into a volume smaller than this.
  • 17:25 - 17:26
    And then.
  • 17:42 - 17:46
    Space itself exploded,
    in a burst of radiant energy.
  • 17:48 - 17:51
    ln those first dazzling moments
  • 17:51 - 17:55
    the newborn universe
    began to expand and cool.
  • 17:56 - 17:59
    Quarks combined
    into protons and neutrons
  • 17:59 - 18:03
    which later attracted electrons
    to form atoms
  • 18:04 - 18:06
    and the vast fog lifted.
  • 18:21 - 18:23
    For hundreds of millions of years
  • 18:23 - 18:27
    the force of gravities slowly drew matter
    together into a gigantic web.
  • 18:28 - 18:30
    The architecture of the cosmos.
  • 18:37 - 18:39
    Two billion years passed
  • 18:40 - 18:44
    clouds of gas and dust condensed
    like giant water drops
  • 18:44 - 18:47
    along the cosmic strands
    and formed galaxies.
  • 19:00 - 19:02
    Where the great ridges of matter crossed
  • 19:02 - 19:05
    galaxies came together in clusters.
  • 19:30 - 19:33
    Some galaxies evolved into gigantic discs
  • 19:33 - 19:36
    and spirals of stars, gas, and dust.
  • 19:38 - 19:41
    Neighboring galaxies trapped
    by their mutual gravity
  • 19:41 - 19:44
    draw together in the fantastic collision.
  • 19:45 - 19:48
    ln real time, it would last a billion years.
  • 20:27 - 20:31
    The force of gravities
    stretch long tails of gas and stars
  • 20:31 - 20:33
    from the huge new galaxy.
  • 20:36 - 20:38
    And yet stars almost never collide
  • 20:39 - 20:42
    so vast are the distances between them.
  • 20:52 - 20:54
    Perhaps ten billion years pass
  • 20:55 - 20:57
    and we encounter our own galaxy:
  • 20:57 - 20:59
    The Milky Way.
  • 21:00 - 21:02
    ln it, stars have formed
  • 21:03 - 21:05
    and some have died.
  • 21:10 - 21:12
    Stars are nuclear furnaces.
  • 21:12 - 21:15
    They shine until they use up their fuel.
  • 21:15 - 21:18
    Massive stars end explosively.
  • 21:33 - 21:36
    These exploding stars, or supernovas
  • 21:37 - 21:39
    send out the elements of life:
  • 21:39 - 21:42
    The oxygen we breathe,
    the carbon in our muscles
  • 21:42 - 21:44
    the iron in our blood.
  • 21:46 - 21:48
    Now a cloud of cosmic gas
  • 21:48 - 21:51
    sprinkled with these elements,
    comes together in the grip of gravity.
  • 21:57 - 22:01
    A new star, our sun, ignites.
  • 22:04 - 22:06
    Around it, planets form.
  • 22:09 - 22:12
    ln their infancy,
    over four billion years ago
  • 22:13 - 22:16
    our Earth and moon
    were bombarded constantly
  • 22:16 - 22:18
    by cosmic dust, asteroids
  • 22:19 - 22:21
    and comets.
  • 23:16 - 23:20
    With violent impacts and volcanic gases
  • 23:20 - 23:24
    acid rain, and potent ultraviolet radiation
    from the sun
  • 23:25 - 23:27
    the young Earth was a very hostile world.
  • 23:31 - 23:35
    And yet the basic ingredients
    of life are already here.
  • 23:42 - 23:43
    Water
  • 23:44 - 23:45
    carbon
  • 23:46 - 23:47
    and energy.
  • 23:51 - 23:55
    Molecules, sheltered by the sea,
    somehow combined
  • 23:55 - 23:58
    multiplied, and gave rise to life.
  • 23:58 - 24:03
    For millions of years,
    Earth's only organisms were tiny bacteria.
  • 24:04 - 24:07
    Some, called blue-green bacteria
  • 24:07 - 24:10
    slowly released tiny bubbles of oxygen
  • 24:11 - 24:15
    and profoundly changed the atmosphere.
  • 24:17 - 24:22
    Above the clouds, some of this oxygen
    formed a thin layer of ozone
  • 24:22 - 24:26
    blocking most of the sun's
    ultraviolet rays.
  • 24:31 - 24:33
    ln this changed environment
  • 24:34 - 24:37
    new organisms flourished
    in the Earth's waters.
  • 24:38 - 24:42
    Colonies of green algae
    produced more oxygen.
  • 24:50 - 24:54
    Then, organisms evolved
    in an astonishing variety of forms.
  • 24:56 - 25:00
    Some with shells or skeletons
    for protection and support.
  • 25:10 - 25:15
    Others evolved complex life cycles,
    like this tiny crustacean.
  • 25:16 - 25:22
    The shallow waters of the seas
    filled with a teaming diversity of life forms.
  • 25:35 - 25:39
    Life's next challenge
    was to colonize the harsh, dry land.
  • 25:43 - 25:48
    Bacteria were first, followed by algae,
    plants, and animals.
  • 26:13 - 26:18
    Vertebrates appeared on land,
    feeding on both plants and animals
  • 26:20 - 26:23
    and gave rise to larger
    and larger life forms.
  • 26:27 - 26:29
    Some of them conquered
    the realm of the air
  • 26:31 - 26:34
    and others, the great open plains.
  • 26:54 - 26:58
    Our cosmic voyage, from the Big Bang
    to the appearance of humans
  • 26:58 - 27:01
    took about 15 billion years.
  • 27:03 - 27:06
    From the beginning, we were explorers
  • 27:06 - 27:09
    inventors and technicians.
  • 27:18 - 27:22
    And in a few thousand years,
    just an instant in cosmic time
  • 27:23 - 27:28
    curiosity and technology
    would take us back toward the stars.
  • 27:58 - 28:00
    Since it was launched into orbit
  • 28:00 - 28:03
    the Hubble space telescope
    has captured images
  • 28:03 - 28:05
    that reveal ever more beautiful
  • 28:05 - 28:09
    and mysterious regions of the universe,
    where stars are dying out.
  • 28:14 - 28:16
    And within the Eagle Nebula
  • 28:16 - 28:20
    strange towers of glowing gas
    are giving birth to new stars.
  • 28:23 - 28:25
    ln the great Orion Nebula
  • 28:25 - 28:30
    discs of dust seem to be turning
    into solar systems just like our own.
  • 28:34 - 28:38
    The grand adventure of cosmic exploration
    is accelerating rapidly
  • 28:38 - 28:42
    taking us into realms
    that once were the stuff of science fiction
  • 28:42 - 28:45
    like the mysterious black hole.
  • 28:51 - 28:55
    Here, a red giant star
    is slowly being consumed
  • 28:55 - 28:59
    its gases swirling into the depths
    of a black hole.
  • 29:04 - 29:08
    Some black holes may be collapsed cores
    of very massive stars
  • 29:08 - 29:12
    with gravity so powerful
    not even light can escape them.
  • 29:13 - 29:17
    But they can be detected from their trap
    and swallow nearby stars.
  • 29:27 - 29:30
    For the first time in our history
  • 29:30 - 29:34
    we now have strong evidence
    that there are planets orbiting other stars.
  • 29:36 - 29:40
    Scientists think there could be millions
    of earth-like planets in our galaxy alone.
  • 29:45 - 29:48
    lf so, do any of them have life?
  • 29:53 - 29:55
    Some radio telescopes search for signals
  • 29:55 - 29:58
    that may reveal the presence
    of alien civilizations.
  • 30:00 - 30:01
    lt's a daunting task.
  • 30:02 - 30:05
    But, if one day we should receive a signal
  • 30:06 - 30:09
    it would forever change our view
    of ourselves
  • 30:09 - 30:11
    and our universe.
  • 30:36 - 30:40
    Telescopes, such as the giant
    Keck Observatory in Hawaii
  • 30:40 - 30:44
    are like time machines
    capturing the faint light
  • 30:44 - 30:47
    that has traveled towards us
    through all of cosmic history.
  • 30:48 - 30:53
    The deeper astronomers look into space,
    the farther back they see in time.
  • 31:09 - 31:12
    The more we learn about the universe
  • 31:12 - 31:15
    the more new mysteries we uncover
  • 31:15 - 31:20
    profound questions for future generations
    of cosmic explorers.
  • 31:24 - 31:27
    Will the universe go on expanding forever?
  • 31:28 - 31:31
    Exactly how did life arise?
  • 31:32 - 31:35
    Could there be other universes
    beyond our cosmic horizon?
  • 31:36 - 31:39
    And are there others
    elsewhere in the universe
  • 31:39 - 31:41
    asking the same things?
  • 31:42 - 31:45
    Even to ask such questions is ambitious.
  • 31:46 - 31:49
    But look how far we've traveled
    since our ancestors
  • 31:49 - 31:53
    took the first steps in our cosmic voyage.
  • 33:30 - 33:35
    Man must understand his universe
    in order to understand his destiny.
  • 33:36 - 33:40
    Who knows what mysteries
    will be solved in our lifetime
  • 33:40 - 33:44
    and what new riddles will become
    the challenge of the new generations?
