    The Museum Of Alien Life
  • 2:03 - 2:04
    To have any hope-
  • 2:04 - 2:06
    of finding alien life,
  • 2:06 - 2:07
    we have to know what to look for.
  • 2:12 - 2:14
    But where do we begin?
  • 2:15 - 2:16
    How do we narrow down...
  • 2:17 - 2:18
    a seemingly infinite set-
  • 2:18 - 2:20
    of possibilities...
  • 2:27 - 2:30
    There's one thing we know for sure...
  • 2:31 - 2:32
    nature will have to play-
  • 2:32 - 2:33
    by her own rules.
  • 2:37 - 2:38
    No matter how strange-
  • 2:38 - 2:40
    alien life might be,
  • 2:40 - 2:41
    is going to be limited-
  • 2:41 - 2:43
    by the same physical...
  • 2:43 - 2:45
    and chemical laws that we are....

    Despite these natural boundaries,

    To guide our thinking,

    this museum of alien life-

    Before we venture-

    too far into the unknown,

    we have to ask ourselves...

    what if alien life-

    is more like us...

    carbon compounds for the biochemistry,

    they will have plenty to choose from.

  • 5:58 - 5:59
    If we ever discover-
  • 5:59 - 6:01
    other carbon based life forms,
  • 6:02 - 6:06
    we will be fundamentally related.
  • 6:08 - 6:11
    They will be our cosmic brother.
  • 6:13 - 6:15
    But would they look anything like us?
  • 6:20 - 6:22
    If they hail from Earth like planets,
  • 6:23 - 6:24
    we could share even more in common,
  • 6:25 - 6:28
    than just our biochemistry.
  • 6:30 - 6:31
    What would life be like-
  • 6:31 - 6:32
    on another planets,
  • 6:32 - 6:33
    if it is evolved?
  • 6:33 - 6:34
    Would it be like,
  • 6:35 - 6:37
    the world today here on Earth?
  • 6:37 - 6:40
    Or would be completely different?
  • 6:40 - 6:41
    There are those,
  • 6:41 - 6:42
    who argue that...
  • 6:42 - 6:44
    from the argument of convergent evolution,
  • 6:45 - 6:48
    if conditions on other planets are similar to here,
  • 6:48 - 6:50
    then we will see very similar life forms...
  • 6:54 - 6:57
    animal and plant-like organisms,
  • 6:57 - 7:00
    that look very familiar.
  • 7:12 - 7:13
    On Earth,
  • 7:13 - 7:15
    certain features like eyesight,
  • 7:15 - 7:17
    echo-location and flight
  • 7:17 - 7:19
    have evolved multiple times,
  • 7:19 - 7:20
    independently...
  • 7:20 - 7:22
    in different species.
  • 7:24 - 7:26
    This process of convergent evolution...
  • 7:26 - 7:29
    could extend to alien planets like Earth,
  • 7:29 - 7:35
    where creatures share similar environmental pressures.
  • 7:35 - 7:37
    It's no guarantee,
  • 7:37 - 7:39
    but there could be certain
  • 7:39 - 7:42
    universalities of life...
  • 7:44 - 7:46
    the greatest hits of evolution...
  • 7:46 - 7:49
    on repeat across the Universe.
  • 7:58 - 7:59
    Each feature would be a tune
  • 7:59 - 8:02
    to its local environment.
  • 8:03 - 8:04
    Dimly lit planets...
  • 8:04 - 8:08
    would produce huge eyes to suck in extra light,
  • 8:08 - 8:11
    like nocturnal mammals.
  • 8:14 - 8:15
    Some people have gone-
  • 8:15 - 8:16
    so far as to say-
  • 8:17 - 8:18
    that human type organism,
  • 8:19 - 8:19
    humanoids,
  • 8:19 - 8:22
    will occur on other planets.
  • 8:26 - 8:27
    The existence of other-
  • 8:27 - 8:29
    human-like organisms...
  • 8:29 - 8:30
    seems unlikely,
  • 8:30 - 8:31
    given the long...
  • 8:31 - 8:33
    convoluted chain of events-
  • 8:33 - 8:34
    that produced us.
  • 8:35 - 8:37
    But we can't rule it out.
  • 8:41 - 8:42
    If just one in every-
  • 8:42 - 8:45
    100 trillion Earth-like planets produced-
  • 8:45 - 8:46
    a human-like form...
  • 8:46 - 8:47
    there could still be...
  • 8:47 - 8:51
    thousands of creatures like us out there...
  • 9:02 - 9:07
    But in reality, we are more likely to find
    something lower on the food chain.
  • 9:10 - 9:11
    Convergent evolution-
  • 9:11 - 9:14
    is also rampant in plant life...
  • 9:14 - 9:16
    and C4 photosynthesis-
  • 9:16 - 9:17
    has arisen independently...
  • 9:17 - 9:19
    over 40 times...
  • 9:21 - 9:24
    Would alien plants look like ours...
  • 9:24 - 9:26
    or something else entirely?
  • 9:37 - 9:37
    On Earth,
  • 9:38 - 9:39
    plants appear green
  • 9:39 - 9:40
    because they absorb
  • 9:40 - 9:41
    the other wavelenghts
  • 9:41 - 9:44
    in the Sun's light spectrum.
  • 9:45 - 9:49
    But stars come in many colors..
  • 9:52 - 9:54
    and alien plants would evolve-
  • 9:54 - 9:55
    different pigments...
  • 9:55 - 9:59
    to adapt to their sun's unique spectrum.
  • 10:04 - 10:08
    Plants feeding off hotter stars
    could appear redder,
  • 10:08 - 10:11
    by absorbing their energy rich bluer light.
  • 10:20 - 10:24
    Around dim Red Dwarfs stars,
    vegetation could appear black,
  • 10:25 - 10:28
    adapted to absorb all visible
    wavelengths of light.
  • 10:45 - 10:48
    Earth itself may have once
    appeared purple,
  • 10:48 - 10:52
    due a pigment called retinal, that was
    an early precursor to chlorophyll.
  • 10:55 - 10:58
    Some think that retinal's molecular simplicity
  • 10:58 - 11:01
    could make it a more universal pigment.
  • 11:04 - 11:09
    If so, we may find that purple,
    is life's favorite color.
  • 11:20 - 11:24
    But the color of alien vegetation
    is more than just a curiosity,
  • 11:26 - 11:29
    it's chemical information that could
    be seen from light years away.
  • 11:35 - 11:39
    Earth plants leave a signature bump
    in the light reflected off our planet.
  • 11:40 - 11:43
    Finding a similar signal from another
    world could point the way
  • 11:44 - 11:45
    to alien vegetation.
  • 11:50 - 11:54
    Perhaps this will be our first glimpse at alien life;
  • 11:55 - 11:58
    a vibrant hue, cast by a distant world.
  • 12:12 - 12:20
    But the biggest influence on life won't be it's host star; it will be it's home planet.
  • 12:21 - 12:23
    What happens, when you change the day - length of a planet?
  • 12:23 - 12:25
    What happens when you change the tilt of a planet?
  • 12:26 - 12:28
    What happens when you change the shape of the orbit?
  • 12:28 - 12:31
    What happens when you change the gravity of a planet?
  • 12:34 - 12:39
    Planets with long, elliptical orbits would see drastic seasons.
  • 12:41 - 12:45
    There could be worlds that appear dead for thousands of years,
  • 12:46 - 12:47
    then suddenly spring to life.
  • 13:03 - 13:07
    Most of the rocky planets discovered so far have been massive "Super Earths".
  • 13:09 - 13:12
    GJ 357 D
    Super Earth
    Distance: ~ 31 Light Years
    Mass: ~ 7× Earth
    Temperature: ~ -53°C
  • 13:13 - 13:15
    How would life evolve on these worlds?
  • 13:19 - 13:22
    In the seas, gravity may not matter much at all.
  • 13:30 - 13:32
    A high - gravity planet isn't high - gravity all over.
  • 13:34 - 13:38
    If you're in the sea, that's where all life starts, there's very nearly no gravity,
  • 13:38 - 13:40
    cause you're much the density as the stuff around you.
  • 13:43 - 13:47
    It's when the animals come out on land, that they feel the gravity.
  • 13:52 - 13:54
    High G - forces [vaguely, gravitational forces] would necessitate
  • 13:54 - 13:57
    large bones and muscle mass in complex life on land.
  • 14:00 - 14:03
    They would also demand a more robust circulatory system.
  • 14:05 - 14:11
    And plant life could be stunted by the energy cost of carrying nutrients under stronger gravity.
  • 14:17 - 14:21
    Low - gravity planets would more easily lose their atmospheres to space;
  • 14:22 - 14:25
    and lack a magnetic field to protect from cosmic rays.
  • 14:36 - 14:39
    But smaller worlds could be home to secret oases;
  • 14:46 - 14:49
    huge cave systems that provide hide-outs for life.
  • 15:03 - 15:11
    With steadier temperatures and protection from cosmic rays, life could thrive underground on planets with deadly surfaces.
  • 15:28 - 15:33
    The smallest possible habitable planets are estimated at 2.5% Earth's mass.
  • 15:35 - 15:38
    If surface life does evolve on these worlds,
  • 15:39 - 15:41
    it could be a sight to behold.
  • 15:45 - 15:47
    Plant life could grow to towering heights,
  • 15:47 - 15:51
    able to carry nutrients higher, at lesser gravity.
  • 15:59 - 16:03
    And without the need for bulky skeletons and muscle mass,
  • 16:03 - 16:06
    animals could have body types, that boggle the mind.
  • 16:22 - 16:28
    Despite our eager imagination, large complex lifeforms
    are probably a cosmic rarity.
  • 16:32 - 16:35
    Here on Earth, it took three
    billion years for evolution
  • 16:35 - 16:37
    to produce complex plant and animal life.
  • 16:40 - 16:43
    Simple organisms are hardier,
    more adaptable
  • 16:43 - 16:44
    and more widespread.
  • 16:48 - 16:51
    The largest collection in the
    museum of alien life
  • 16:51 - 16:54
    would likely be the Hall of Microbes.
  • 17:10 - 17:15
    Yet finding even the tiniest alien microbe
    would be a profound discovery.
  • 17:31 - 17:34
    And bite-sized life could leave
    a big footprint.
  • 17:36 - 17:40
    Like stromatolites on Earth, layers of
    microbes could build up into huge
  • 17:40 - 17:41
    rock mounds over time.
  • 17:42 - 17:44
    Leaving behind eery structures.
  • 17:49 - 17:51
    And in big enough numbers
    some alien
  • 17:51 - 17:54
    bacteria could leave a
    distinct biosignature,
  • 17:56 - 17:59
    by exhaling gases that wouldn't
    coexist naturally:
  • 17:59 - 18:01
    like oxygen and methane.
  • 18:07 - 18:09
    There's ways to make oxygen without life.
  • 18:09 - 18:11
    There's ways to make methane without life.
  • 18:11 - 18:13
    But to have them in the atmosphere together?
  • 18:13 - 18:17
    Is almost impossible unless you've got
    biology making those gases at the surface.
  • 18:18 - 18:21
    And it would have a imprint on
    the planet's spectrum of colors.
  • 18:23 - 18:26
    Next generation space telescopes
    could find a signal like this,
  • 18:29 - 18:31
    on a world not far from home.
  • 18:32 - 18:37
    The closest Sun-like star with an
    Earth-like exoplanet in the
  • 18:37 - 18:40
    habitable zone is probably only
    20 light years away
  • 18:40 - 18:42
    and can be seen with a naked eye.
  • 18:46 - 18:52
    But there may be an even easier target to aim for than tiny Earth-like planets.
  • 18:55 - 19:02
    The Brown Dwarfs: too small to
    be stars, to big to be planets.
  • 19:06 - 19:10
    Most Brown Dwarfs are too hot
    to support life as we know it.
  • 19:11 - 19:13
    But some are just cold enough.
  • 19:14 - 19:15
    WISE 0855-0714
  • 19:15 - 19:15
    WISE 0855-0714
    Sub-Brown Dwarf
  • 19:15 - 19:15
    WISE 0855-0714
    Sub-Brown Dwarf
    Distance: 7 Light Years
  • 19:15 - 19:16
    WISE 0855-0714
    Sub-Brown Dwarf
    Distance: 7 Light Years
    Mass: 3.10x Jupiter
  • 19:16 - 19:23
    WISE 0855-0714
    Sub-Brown Dwarf
    Distance: 7 Light Years
    Mass: 3.10x Jupiter
    Temperature: -50 - -13ºC
  • 19:24 - 19:29
    All the prime elements for life have
    been detected inside their atmospheres.
  • 19:32 - 19:36
    And within these clouds, some layers
    would provide ideal temperatures
  • 19:36 - 19:37
    and pressures for habitability.
  • 19:46 - 19:49
    There could be photosynthetic
    plankton in these skies,
  • 19:50 - 19:52
    kept aloft by churning upwinds.
  • 19:58 - 20:01
    And with enough force, these upwinds
    could even support larger,
  • 20:01 - 20:03
    more complex life.
  • 20:06 - 20:07
    Predadors.
  • 20:15 - 20:19
    There are over 25 billion Brown
    Dwarfs in our galaxy alone,
  • 20:19 - 20:24
    and their sizes will make them
    easier targets for study.
  • 20:27 - 20:35
    The first specimen we discover from the museum of life may not be from a planet at all.
  • 20:44 - 20:46
    This raises a crucial question:
  • 20:48 - 20:50
    what if we've been looking in
    all the wrong places?
  • 20:53 - 20:55
    What if nature has other ideas?
  • 20:59 - 21:01

    EXHIBIT II
    LIFE AS WE DON'T KNOW IT
  • 21:03 - 21:08
    EXHIBIT II
    LIFE AS WE DON'T KNOW IT
    EXOTIC BIOCHEMISTRIES
  • 21:21 - 21:26
    Most of the Universe is too cold or too
    hot for liquid water and the
  • 21:26 - 21:28
    biochemistry that supports
    life as we know it.
  • 21:32 - 21:34
    But in case our biases are misleading,
  • 21:35 - 21:36
    we have to cast a wide net.
  • 21:39 - 21:41
    To search for life outside
    the habitable zone,
  • 21:42 - 21:45
    in places that seem wildly hostile to us.
  • 21:50 - 21:53
    Exotic environments will demand
    exotic biochemistries.
  • 21:54 - 21:57
    And while no element can match
    carbon's versatility,
  • 21:57 - 21:59
    one contender is a front runner.
  • 22:08 - 22:11
    At first glance, silicon seem
    similar to carbon.
  • 22:13 - 22:17
    It forms the same four-way bonds and is
    also abundant in the Universe.
  • 22:19 - 22:23
    But a closer look reveals that these
    two elements are false twins.
  • 22:27 - 22:32
    Silicon bonds are weaker and less prone
    to forming large complex molecules.
  • 22:36 - 22:40
    Despite this, they can withstand
    a wider range of temperatures,
  • 22:41 - 22:44
    opening up intriguing possibilities.
  • 22:47 - 22:50
    Life based on the silicon atom
    instead of carbon,
  • 22:51 - 22:53
    would be more resistant to
    the extreme cold.
  • 22:55 - 22:58
    Providing a whole new range of weird forms.
  • 23:01 - 23:03
    But silicon has a problem:
  • 23:05 - 23:08
    in the presence of oxygen,
    it binds into solid rock.
  • 23:10 - 23:13
    To avoid turning to stone, silicon beings
  • 23:13 - 23:16
    might be confined to oxygen free environments.
  • 23:17 - 23:19
    Like Saturn's frigid moon, Titan.
  • 23:19 - 23:23
    TITAN
    Saturnian Moon
    Distance: 1,2 Million KM
    Mass: .023X Earth
    Temperature: -129ºC
  • 23:23 - 23:27
    Its vast lakes of liquid methane and
    ethane could be an ideal medium
  • 23:27 - 23:29
    for silicon-based life,
  • 23:29 - 23:31
    or other radical biochemistries.
  • 23:37 - 23:40
    Without ample sunlight, beings on worlds
  • 23:40 - 23:43
    like Titan, would likely be chemosynthetic.
  • 23:43 - 23:46
    Deriving their energy by
    breaking down rocks.
  • 24:02 - 24:04
    Such life forms could have ultra slow
  • 24:04 - 24:08
    metabolisms and life cycles
    measured in millions of years.
  • 24:16 - 24:21
    And frozen worlds aren't the only possible
    harbor for exotic life.
  • 24:23 - 24:23
    CoRoT-7B
  • 24:23 - 24:23
    CoRoT-7B
    Super Earth
  • 24:23 - 24:24
    CoRoT-7B
    Super Earth
    Distance: ~520 Light Years
  • 24:24 - 24:24
    CoRoT-7B
    Super Earth
    Distance: ~520 Light Years
    Mass: -8x Earth
  • 24:24 - 24:26
    CoRoT-7B
    Super Earth
    Distance: ~520 Light Years
    Mass: -8x Earth
    Temperature: 1026-1526ºC
  • 24:26 - 24:30
    In high temperatures, typically rigid
    silicon oxygen bonds become more
  • 24:30 - 24:32
    flexible and reactive.
  • 24:33 - 24:35
    Triggering more dynamic chemistry.
  • 24:40 - 24:43
    This has led to a truly bizarre proposal:
  • 24:44 - 24:49
    silicon-based life forms that live
    inside molten silicate rock.
  • 25:01 - 25:03
    In theory, these forms could even exist
  • 25:03 - 25:06
    deep beneath the Earth inside
    magma chambers
  • 25:06 - 25:08
    as part of a shadow biosphere.
  • 25:12 - 25:17
    If so, then the aliens are right
    under our noses.
  • 25:21 - 25:23
    Other shadow biospheres have
    been proposed:
  • 25:24 - 25:27
    forms of life living alongside us
    that we don't even know are here.
  • 25:28 - 25:30
    Including tiny RNA-based life, small
  • 25:30 - 25:34
    enough to go undetected by
    existing instruments.
  • 25:47 - 25:51
    Clouds of dust and empty space might
    seem like the last place you'd expect
  • 25:51 - 25:52
    to find anything living.
  • 25:54 - 25:57
    But when cosmic dust makes
    contact with plasma,
  • 25:58 - 25:59
    a type of ionized gas,
  • 25:59 - 26:01
    something strange happens.
  • 26:06 - 26:08
    In simulated conditions, dust particles,
  • 26:08 - 26:11
    have been seen spontaneously
    self-organizing
  • 26:11 - 26:14
    into helical structures that resemble DNA.
  • 26:19 - 26:22
    These plasma crystals even begin
    to exhibit life-like behavior:
  • 26:24 - 26:28
    replicating, evolving into more stable
    forms and passing on information.
  • 26:36 - 26:39
    Could these crystals be considered alive?
  • 26:42 - 26:49
    To some researchers, they meet all the criteria
    to qualify as inorganic life forms.
  • 26:52 - 26:57
    So far, we have only ever seen them in computer simulations.
  • 26:58 - 27:05
    But some speculate we could find them
    among the ice particles in the rings of Uranus.
  • 27:12 - 27:16
    Plasma is the most common state
    of matter in the Universe.
  • 27:18 - 27:21
    If complex evolving plasma
    crystals really exist
  • 27:21 - 27:23
    and if they can be considered life,
  • 27:23 - 27:25
    they could be its most common form.
  • 27:39 - 27:43
    Or perhaps life is lurking in the
    polar opposite environment:
  • 27:43 - 27:47
    inside the hearts of dead stars.
  • 27:51 - 27:54
    When massive suns explode, some collapase into
  • 27:54 - 27:57
    ultra dense cores called neutron stars.
  • 27:57 - 27:58
    PSR B1509-58
    Neutron Star
    Distante: 17,000 Light Years
    Spin Rate: ~7/second
  • 27:58 - 28:02
    Hulking masses of atomic nuclei
    crammed together like sardines.
  • 28:06 - 28:08
    Conditions on the surface are mind-boggling:
  • 28:09 - 28:12
    gravity is a hundred billion times
    stronger than Earth's.
  • 28:16 - 28:19
    But beneath their iron nuclei
    crust lies something strange:
  • 28:21 - 28:25
    a hot dense sea of neutrons
    and subatomic particles.
  • 28:35 - 28:37
    Stripped of their electron shells, these
  • 28:37 - 28:40
    nuclei would obey entirely
    different laws of chemistry,
  • 28:40 - 28:43
    based not on the electromagnetic force,
  • 28:43 - 28:45
    but the strong nuclear force,
  • 28:45 - 28:47
    which binds nuclei together.
  • 28:50 - 28:52
    In theory, these particles could link-up
  • 28:52 - 28:55
    to form larger macronuclei,
    which could then
  • 28:55 - 28:58
    combine into even bigger super nuclei.
  • 29:07 - 29:10
    If so, then this bewildering environment
  • 29:10 - 29:12
    would mimic the basic conditions for life.
  • 29:12 - 29:17
    Heavy nucleon molecules floating
    in a complex particle ocean.
  • 29:23 - 29:25
    Some scientists have proposed
    the unimaginable:
  • 29:27 - 29:30
    exotic life forms drifting through
    the strange particle sea,
  • 29:31 - 29:36
    living, evolving and dying on
    incomprehensibly fast time scales.
  • 29:56 - 30:01
    There's probably no chance of ever detecting
    such a strange breed of life.
  • 30:03 - 30:08
    But there may be hope for finding
    an even more exotic form.
  • 30:19 - 30:22
    Life is not something that has to evolve naturally.
  • 30:26 - 30:27
    It can be designed.
  • 30:42 - 30:45
    And once intelligence is introduced into the evolutionary process,
  • 30:46 - 30:48
    a Pandora's Box is opened.
  • 31:06 - 31:13
    Free from typical biological limitations, synthetic and machine - based life could be the most successful of all.
  • 31:17 - 31:20
    It could thrive almost anywhere, including the vaccum of space,
  • 31:21 - 31:25
    opening up vast frontiers unavailable to biological organisms.
  • 31:32 - 31:37
    And compared to the glacial pace of natural selection, technical evolution
  • 31:37 - 31:42
    allows exponentially faster growth, adaptability and resilience.
  • 31:56 - 32:00
    By some estimates, autonomous, self - replicating machines could colonize
  • 32:00 - 32:04
    an entire galaxy in as little as a million years.
  • 32:19 - 32:23
    We can't predict how hyper - intelligent life would organise itself,
  • 32:27 - 32:30
    but in theory, there could be convergent evolution at play.
  • 32:32 - 32:38
    The electrical properties of Silicon might make it a universal basis for machine intelligence,
  • 32:39 - 32:42
    a redemption for its biological shortcomings.
  • 33:03 - 33:05
    With all its potential advantages,
  • 33:05 - 33:10
    With all its potential advantages, machine life may even be a universal endpoint:
  • 33:10 - 33:15
    With all its potential advantages, machine life may even be a universal endpoint: the apex of evolutionary process.
  • 33:53 - 33:58
    As the universe ages, perhaps machine intelligence would come to dominate,
  • 33:59 - 34:04
    and naturally occurring biological life will be viewed as a quaint starting point.
  • 34:10 - 34:12
    Perhaps, we ourselves will lead this transition,
  • 34:13 - 34:20
    and the great human experiment would be merely a first link in a sprawling intergalactic chain of life.
  • 34:51 - 35:02
    In the end, we are still the only beings we know of in the museum of alien life.
  • 35:07 - 35:10
    To truly know ourselves, we will have to know:
  • 35:10 - 35:13
    To truly know ourselves, we will have to know: are we the only ones?
  • 35:27 - 35:32
    Loren Eisley has said, that one does not meet oneself until
  • 35:32 - 35:37
    one catches the reflection from an eye other than human.
  • 35:39 - 35:43
    One day that eye may be that of an intelligent alien.
  • 35:46 - 35:51
    And the sooner we eschew our narrow view of evolution,
  • 35:52 - 35:59
    the sooner we can truly explore our ultimate origins and destinations.
  • 36:04 - 36:07
    We have seen what could be out there.
  • 36:10 - 36:13
    And we know how we might find it.
  • 36:16 - 36:19
    There is only one thing left to do.
  • 36:22 - 36:26
    Go looking.

LIFE BEYOND II: The Museum of Alien Life (4K)
Description:

Soundtrack: https://bit.ly/3lo7cnH Support this project on Patreon: http://patreon.com/melodysheep

What if there was a museum that contained every type of life form in the universe? This experience takes you on a tour through the possible forms alien life might take, from the eerily familiar to the utterly exotic, ranging from the inside of the Earth to the most hostile corners of the universe.

New research is upending our idea of life and where it could be hiding: not just on Earth-like planets, where beings could mimic what our planet has produced, but in far flung places like the hearts of dead stars and the rings of gas giant planets. Nowhere in the universe is off limits.

Only when we know what else is out there will we truly know ourselves. This thought experiment will give us a glimpse into what could be out there, how we might find it, and just how far nature’s imagination might stretch.
