from it’s insane depths to its
00:01
scientific mysteries stay tuned to
00:04
number one to find out the top 10 facts
00:06
about the Mariana Trench
00:12
[Music]
00:18
number ten it’s one of the deepest parts
00:22
of our world when you think about our
00:24
world you likely think about how far
00:27
we’ve come in terms of building up our
00:29
cities or how high we’ve gone in terms
00:31
of space travel and whatnot
00:33
you might even look at the oceans and
00:35
wonder how deep it actually is to the
00:37
bottom of the ocean well as the Mariana
00:40
Trench has shown us it’s pretty deep in
00:42
fact it’s so deep that some think it can
00:45
go even deeper than we know just to
00:48
reach the Mariana Trench you have to go
00:50
30 6070 feet specifically you have to do
00:55
it off of the nearby Mariana Islands but
00:58
the point is still there to be made this
00:59
is a massively deep trench if you still
01:03
need some context as to how deep the
01:05
trench really is think about it like
01:06
this Mount Everest is the tallest
01:09
mountain above sea level in the world
01:10
right and it’s a great honor to climb
01:13
all the way up there and survive right
01:16
well if you were to pick up the entire
01:19
mountain from tip to summit turn it
01:21
upside down and stick it into the ocean
01:23
you still wouldn’t reach the trench
01:25
you’d still be about 7,000 feet away in
01:29
fact that’s how deep the trench is or at
01:32
least just to reach the top of it which
01:34
begs the question number 9 how low does
01:38
it go that is the question isn’t it and
01:42
to be completely honest we have no true
01:45
clue the fact is that although we’ve
01:47
sent people and probes and other devices
01:50
to try and scan the depth and the width
01:52
of the place there’s still no indication
01:54
as to how deep it truly goes there are
01:57
actually sections of the trench and one
01:59
of them is the Challenger Deep which is
02:01
said to be the deepest part of the
02:02
trench but because we can’t explore it
02:04
it will there’s a very good chance that
02:06
there are even deeper parts of the
02:08
trench and by that extension deeper
02:11
parts of our own ocean a bit you’re
02:14
getting kind of a skel vertigo huh
02:16
because all of this just goes to show
02:18
the ocean is much much deeper than
02:20
anyone could have imagined which also
02:23
makes it a place that humans definitely
02:25
want to explore because nothing
02:26
terrifies a human scientist more than a
02:29
question that has gone unanswered
02:31
or an incredible period of time but
02:33
seriously how low does it go sorry but
02:37
there’s just no way of knowing right now
02:40
number eight deep trouble before we move
02:44
on take a moment to like this video and
02:46
join the zero to hero community by using
02:48
the buttons below believe it or not
02:51
we’ve known about the Mariana Trench
02:52
since the 1800s 1875 to be exact
02:57
however just because we knew it was
02:59
there didn’t mean we could get to it in
03:01
fact it took us nearly a hundred years
03:04
to get something strong enough to go
03:06
down there and start scanning the area
03:08
what do I mean by strong enough well
03:11
what you need to remember is that water
03:13
and there are similar in many ways not
03:15
the least of which is that air makes up
03:17
water in part and because of that they
03:19
can both increase in pressure in a
03:21
significant way the deeper you go into
03:24
the ocean
03:25
the more pressure of water builds up
03:27
that’s why scuba divers can only go so
03:29
far on their own once you get to about
03:31
400 feet below sea level the pressure of
03:34
the ocean starts to grow incredibly
03:36
strong and it can severely hurt the
03:38
human body if you’ve ever heard of the
03:41
bends it happens when a diver goes into
03:43
a deep pressure zone and then quickly
03:45
rises to a lower pressure zone this
03:48
causes the body to be pressurized and
03:50
depressurize too quickly and could cause
03:52
serious health issues if you go down too
03:55
far into the ocean you’ll literally be
03:57
compressed by the pressure and not in a
04:00
fun way think of it like a pop can being
04:03
crushed by your hand and that what’s
04:05
never happened before to a human in some
04:07
areas the pressure is so deep that you’d
04:10
likely be crushed into oblivion or even
04:13
turn inside out seriously
04:16
fun fact we have retrieved creatures
04:18
from the Mariana Trench and attempted to
04:20
bring them to the surface key word here
04:22
is attempted because the creatures that
04:26
somehow survive in the Mariana Trench
04:27
are so used to the pressures of the
04:30
water that any attempt to bring them
04:31
into lighter pressure areas destroys
04:34
them it’s not pretty
04:36
hearing all of this you might think it’s
04:38
impossible to get down to the trench and
04:40
survive but number seven three
04:44
explorers it has happened before twice
04:48
actually in total only three people in
04:50
the history of the world have ever made
04:52
it to the Mariana Trench and the trips
04:54
were quite spread out from one another
04:56
the first of these two trips were done
04:58
in 1960 85 years after the discovery of
05:02
the trench scientist Jacques Piccard and
05:05
US Navy lieutenant Don Walsh took a
05:07
submarine and went down into the deepest
05:09
depths of the ocean and were able to
05:12
successfully make it to the trench
05:13
itself in fact despite being the earlier
05:16
of the two trips they went the deepest
05:18
into the trench but hold on there’s a
05:21
catch for though they made it down their
05:23
sub wasn’t fully prepared for the
05:25
adventure and so after about 20 minutes
05:27
the enormous pressure of the ocean
05:29
depths started to crush the submarine
05:32
and the two were forced to retreat then
05:35
there was the trip made in 2012
05:37
fifty-two years after the original
05:39
journey by none other than legendary
05:41
filmmaker James Cameron he didn’t go
05:44
down in a submarine though but in a solo
05:46
depth pot of sorts and although he
05:48
didn’t go as deep as Picard and Walsh he
05:50
was able to stay down there for hours
05:52
and all throughout the process take
05:54
pictures and film of the life within the
05:56
trench since then many unmanned subs and
05:59
probes have gone to the trench with
06:01
mixed levels of success fun fact more
06:05
people have touched the moon’s surface
06:07
that have touched the waters of the
06:09
Mariana Trench number 6 no light imagine
06:14
you’re on a submarine and you’re going
06:16
down into the Mariana Trench you finally
06:18
reach it and you look outside your
06:20
window to observe it what do you see
06:23
trick question you actually see nothing
06:26
not because nothing exists in the
06:29
Mariana Trench is just an illusion this
06:31
isn’t a christopher nolan movie after
06:33
all but rather you can’t see anything
06:36
because the light of the sun doesn’t
06:38
reach the dips of the trench the reason
06:41
we see in the world today is because the
06:42
Sun emits rays that reach the earth and
06:44
by extension our eyes but the 36,000
06:48
foot depth of the ocean is too deep for
06:50
the sunlight to reach and so if you go
06:53
into the trench you have to bring your
06:55
own source of light to look around
06:57
because there’s very
06:58
within the trench itself to light your
07:00
way for the record both the sub and pod
07:03
the win into the trench had their own
07:05
flashlights and lamps to illuminate the
07:07
area and thus see what was there number
07:11
five the trench is old you might think
07:14
that it’s hard to gauge the age of
07:16
something like the oceans and their
07:17
waters but in fact it’s actually
07:19
something that scientists are able to do
07:21
quite well this is because they use
07:23
tests to determine how old the ocean
07:25
waters are and then determine how they
07:27
factor into the age of the world itself
07:29
the Mariana Trench is believed to be one
07:32
of the oldest seabed still on earth at
07:34
present scientists believe that it is
07:36
one hundred and eighty million years old
07:39
which could be why so little is known
07:41
about it and how it formed without
07:43
interference from man
07:44
number four plenty of things live down
07:47
there after everything you’ve heard
07:50
about the Mariana Trench you might think
07:52
that the place is uninhabitable I mean
07:54
it has pressure that can take you out
07:56
and no sunlight to light your way so
07:58
what kind of things could live down
08:00
there well a lot actually first and
08:03
foremost there’s a lot of simple life
08:05
creatures that live in the trench
08:07
including more than 200 species of
08:09
microorganisms but it’s not all simple
08:12
life there are types of sharks like the
08:14
goblin shark that reside there and the
08:17
infamous angler fish that has an antenna
08:20
that helps lure its prey into their doom
08:22
you may have seen that one on Finding
08:24
Nemo but although we do know some of the
08:27
things that live in the trench we don’t
08:29
know all of them and that’s why many are
08:31
still sinning craft into the depths
08:33
because they want to know all that lives
08:35
there number three hot and cold given
08:40
that there is no sunlight reaching the
08:41
Mariana Trench you might expect the
08:43
waters of the area to be incredibly cold
08:45
and you’d be partially right the average
08:48
temperature is between 34 and 39 degrees
08:51
Fahrenheit
08:52
however because of how deep it is and
08:54
how close it is to the Earth’s core
08:56
there are actually places nearby that
08:59
are blazing hot how is that possible
09:02
well it’s because of geothermal vents
09:05
these vents are connected to the Earth’s
09:07
core and can shoot out streams of air
09:09
and water that can get up to seven
09:11
hundred degrees and while that may seem
09:14
like a death trap it’s actually a
09:15
necessary thing as this influx of water
09:18
brings more minerals and nutrients to
09:20
the area thus providing sustenance to
09:22
the local wildlife number two it has its
09:26
own mythology if you’ve ever heard the
09:28
phrase people fear what they don’t
09:30
understand then you’ll understand how a
09:32
place like the Mariana Trench is so
09:34
scary to some after all we know that
09:37
some very scary creatures live down
09:39
there so it goes to reason that there
09:40
could be even more scary creatures in
09:42
the waters of the Mariana Trench as well
09:44
to that end there have been many books
09:47
and stories written about what may be
09:49
down there and one of the most popular
09:51
ones which was actually turned into a
09:53
movie last year is called the mick a
09:56
story about the infamous Megalodon shark
09:58
of prehistoric times and how a couple of
10:01
them actually survived very sixteen
10:03
tchen events and found a way out of the
10:05
trench and onto the surface this isn’t
10:08
true obviously that we knew of but it
10:12
doesn’t stop people from using the
10:14
trench as a plot device number one
10:17
there’s still a lot we don’t know
10:19
three explorers numerous unmanned subs
10:22
and probes later the truth is the
10:25
Mariana Trench is still a mystery to us
10:27
in a very large scale its natural
10:29
pressure and lack of light make it very
10:31
difficult to study for long periods of
10:33
time and because of that there’s so much
10:35
in there that we just don’t know there
10:37
could be dozens if not hundreds of new
10:40
animals and plant species down there we
10:43
could find a tunnel that leads right to
10:45
the Earth’s core or something else even
10:47
more remarkable this is a mystery that
10:50
many want to solve and so until it’s
10:52
entirely mapped out everyone wants to be
10:55
the one that discovers the next big
10:56
thing from the Mariana Trench what do
10:59
you think about the mysteries of the
11:00
ocean let us know in the comments below
11:02
in take care
11:06
