CHAPTER II[br]The Museum Of Alien Life
0:02:02.805,0:02:03.657
To have any hope-
0:02:03.657,0:02:05.506
of finding alien life,
0:02:05.537,0:02:07.408
we have to know what to look for.
0:02:12.060,0:02:13.945
But where do we begin?
0:02:15.303,0:02:16.446
How do we narrow down...
0:02:16.568,0:02:18.068
a seemingly infinite set-
0:02:18.068,0:02:20.175
of possibilities...
0:02:27.310,0:02:29.968
There's one thing we know for sure...
0:02:30.683,0:02:32.045
nature will have to play-
0:02:32.075,0:02:33.375
by her own rules.
0:02:36.791,0:02:38.166
No matter how strange
0:02:38.196,0:02:39.806
alien life might be,
0:02:40.386,0:02:41.180
is going to be limited-
0:02:41.220,0:02:42.596
by the same physical...
0:02:42.606,0:02:44.756
and chemical laws that we are....

On top of this,[br]6 CO² + 6 H²O + Light → C⁶H¹²O⁶ + 6 O²
0:02:52.312,0:02:52.733
On top of this,
0:02:53.244,0:02:53.694
each alien environment will further limit-
0:02:53.694,0:02:55.239
each alien environment will further limit-[br]-Hydrogen-
0:02:55.239,0:02:55.672
each alien environment will further limit-[br]-Oxygen-
0:02:55.672,0:02:57.374
what kinds of life forms can evolve there.[br]-Oxygen-
0:02:57.374,0:02:59.376
what kinds of life forms can evolve there.[br]-Nitrogen-
0:03:06.992,0:03:09.189
Despite these natural boundaries,
0:03:09.243,0:03:12.206
the possibilities are staggering to imagine.
0:03:14.235,0:03:15.640
Trillions of planets,
0:03:15.778,0:03:17.878
each a unique cauldron of chemicals,
0:03:17.924,0:03:23.076
undergoing their own complex evolution.
0:03:28.300,0:03:33.548
To guide our thinking, this museum of alien life[br]will be divided into two exhibits:
0:03:35.768,0:03:40.185
Life as we know it: home to beings [br]with bio-chemistries like ours.
0:03:41.964,0:03:47.921
And life as we don't know it: home to beings [br]that challenge our concept of life itself.
0:03:54.132,0:03:56.629
Before we venture too far [br]into the unknown,
0:03:57.103,0:03:58.587
we have to ask ourselves:
0:04:00.136,0:04:03.005
what if alien life is more [br]like ours than we think?
0:04:10.820,0:04:12.729
EXHIBIT I
0:04:12.729,0:04:15.017
EXHIBIT I[br]LIFE AS WE KNOW IT
0:04:15.017,0:04:15.435
EXHIBIT I[br]LIFE AS WE KNOW IT[br]CARBON & WATER BASED
0:04:15.435,0:04:20.798
If there's one feature that unites us with [br]these other specimes in this museum, it's carbon.
0:04:25.007,0:04:29.380
Carbon is ubiquitous, it's one of the [br]most common elements in the universe,
0:04:29.745,0:04:32.751
and is very good at forming [br]large stable molecules.
0:04:37.293,0:04:41.502
Carbon has the rare ability to form four way[br]bounds with other elements
0:04:41.807,0:04:44.708
and to bind to itself in [br]long, stable chains;
0:04:46.424,0:04:49.624
enabling the formation of [br]huge complex molecules.
0:04:56.197,0:04:59.093
This versatility makes carbon the center piece
0:04:59.093,0:05:01.130
in the moleculary machinery of life.
0:05:03.520,0:05:07.742
And the same carbon compounds that we use[br]have been found far from Earth,
0:05:08.736,0:05:10.087
clinging to meteorites
0:05:12.359,0:05:15.623
and floating in far off [br]clouds of cosmic dust.
0:05:18.670,0:05:23.518
The building blocks of life drifting [br]like snow through the universe.
0:05:30.162,0:05:34.920
And if alien life has selected other carbon[br]compounds for the biochemistry,
0:05:35.783,0:05:37.413
they will have plenty to choose from.
0:05:42.088,0:05:47.570
Scientists recently identified over a [br]million possible alternatives to DNA:
0:05:48.588,0:05:49.862
all carbon based.
0:05:57.948,0:06:00.795
If we ever discover other [br]carbon based life forms,
0:06:01.650,0:06:03.973
we will be fundamentally related.
0:06:07.928,0:06:09.840
They will be our cosmic brother.
0:06:13.296,0:06:15.137
But would they look anything like us?
0:06:19.975,0:06:21.742
If they hail from Earth like planets,
0:06:22.857,0:06:24.471
we could share even more in common,
0:06:25.065,0:06:26.417
than just our biochemistry.
0:06:29.826,0:06:33.104
What would life be like in another[br]planets, if its evolved?
0:06:33.566,0:06:36.246
Would it be like, the world [br]today here on Earth?
0:06:37.477,0:06:38.736
Or would be completely different?
0:06:40.504,0:06:42.121
There are those, who argue that
0:06:42.456,0:06:44.470
from the argument of convergent evolution,
0:06:44.803,0:06:50.206
if conditions on other planets are similar to here, then we will see very similar life forms;
0:06:54.726,0:06:58.236
animal and plant-like organisms, that look very familiar.
0:07:12.238,0:07:16.618
On Earth, certain features like eyesight, echo-location and flight
0:07:16.628,0:07:20.812
have evolved multiple times, independently, in different species.
0:07:23.648,0:07:28.978
This process of convergent evolution could extend to alien planets like Earth,
0:07:29.222,0:07:32.242
where creatures share similar environmental pressures.
0:07:35.632,0:07:40.372
It's no guarantee, but there could be certain universalities of life;
0:07:44.337,0:07:48.337
the greatest hits of evolution on repeat across the Universe.
0:07:58.040,0:08:02.040
Each feature would be a tune to its local environment.
0:08:02.798,0:08:06.798
Dimly lit planets would produce huge eyes to suck in extra light, like nocturnal mammals.
