the earth isn't flat this is something
we've known now for thousands of years
aristotle approved it empirically by
traveling to egypt and witnessing new
constellations of stars from the other
side of the globe
after eradostinis used no more than a
stick and light from the sun to
calculate the earth's circumference in
the time of ancient greece
yet throughout history groups of people
have been constantly re-emerging to push
the notion that the earth our tiny blue
planet floating in space
is in fact flat
the idea first resurfaced in recent
history in the 1800s then a society of
flat earthers was set up in the 1950s
transforming the group from conspiracy
theorists to an organization with
thousands of members
as the internet began to grow in
popularity so did this organization
in no time flat earthers began growing
in number attracting some pretty well
known members of society these included
movie stars rappers and professional athletes
flat earth theorists have different
models supporting their idea perhaps the
most popular is that the arctic or the
north pole is at the center of the
planet while antarctica surrounds its
edges with thick and long walls of ice
a pancake shaped earth floating in space
as the sun and other planets rotate
above it like a celestial carousel
with all the evidence in the world to
prove that this isn't the case why do
thousands of people still believe that
the earth is flat including one-third of
american millennials
the truth is a combination of a lot of
different things that we really don't
have time to go into in today's video
but with all the popularity this topic gets
gets
it's only right that we ponder the concept
concept
what if the earth was actually flat how
different would our world be from what
first if the earth was flat we'd all be
dead because gravity
gravity
our understanding of gravity has
developed throughout the years from
being a force that pulls us towards the
center of mass to being reimagined as
the curvature of space-time that sets
the course for planets to rotate around
their stars
gravity is the reason that earth and all
other planets are round
imagining a flat earth would mean that
gravity as we know it must be having no effect
effect
but let's say for the sake of argument
that gravity would still have an effect
it's unclear how gravity would behave on
a flat planet
knowing what we do suggest that it would
pull towards the center of the disc
shaped earth at its north pole or the
arctic this means that the further you
get away from the center of the disk the
stronger gravity pulls you back towards
the center
as a result trying to reach the supposed
ice walls of antarctica at the edge
would be impossible as the gravitational
pull would make it seem as if we're
climbing a hill that only gets steeper
oceans seas rivers streams and all other
water bodies would converge at the
center of the planet
rain snow and hail would also fall
towards the center while trees would
grow diagonally developing in the
opposite direction of gravity's pool
the effects of flat earth gravity
doesn't end here
as more air gets sucked into the earth's
center it creates an atmosphere that
would be lung crushing close to the
north pole and without enough oxygen to
breathe at the outer edges
earth would already be so uninhabitable
to life as we know it and it's only just
the beginning
without its spherical shape our planet
would lose its layered structure and
behave very differently earth is made up
of three layers with the densest
material sinking to the core the lighter
making of the mantle and the lightest
making up the crust
the outer core is composed of molten
iron and nickel that acts as a giant
magnet creating earth's magnetic field
it's what protects our atmosphere from
the sun's harmful solar winds and
without it our atmosphere would
dissipate our oceans would spill into
space leaving earth a lifeless barren
land similar to mars
but suppose somehow we managed to
survive all of gravity's grueling ways
to destroy us our living experience on a
dis-shaped planet would still be very different
different
flattening earth will increase its
surface area by two and a half times
this means traveling across the planet
instead of around it would take
significantly longer
it's also unlikely that satellites would
be able to orbit or more precisely hover
above a flat earth
without any satellites we'd lose access
to gps services leaving us without
navigation synchronized time or or the
ability to perform all sorts of global
financial transactions
having no satellites also means that we
won't be able to study our planet from
the atmosphere
grace the gravity recovery and climate
experiment for example was the satellite
that was launched in 2002 to take
detailed measurements of the earth and
collect data to significantly enhance
our understanding of global climate patterns
patterns
it's a mission still being carried on by
grace fo which was launched in 2018.
without such satellites our
understanding of our planet would be limited
limited
for a long time humans thought that we
were at the center of the universe it
wasn't until 1543 that polish scientist
nicolas copernicus first hypothesized
that ours is just another planet
revolving around a star
yet almost 500 years later flat earthers
still believe that we're at the center
of the universe
they propose this through two models
with the only difference between them
being how the sun rotates around us
in the first model the sun circles above
the earth and sheds its light in warmth
on certain regions like a high-powered
desk lamp
if this is how our world was we should
be able to see the sun from anywhere
across the globe even if it isn't
currently shining in that region
it would also mean that day and night as
we know it simply wouldn't exist because
if the sun doesn't rotate then it shines
on the same parts of the globe all day
long leaving some places an internal
sunshine and the rest of the planet in
utter darkness
to help account for the day cycles the
second model proposes that the sun is
rotating spherically around the earth
if this happened our entire planet would
witness daytime and nighttime
simultaneously because the whole planet
would be brightened and darkened at the
same time each day
in both of these models there would be
no time zones no seasons and no moon in
our depleted atmosphere
the view of the night sky would be the
same from anywhere in the world and our
view into space would be limited to the
patch of the galaxy directly above us
because again without any rotation
we'll be staring at the same thing every
single time we look up
it gets worse if the sun is as big as it
currently is
it would burn the planet
on the other hand if it was as small as
these theories suggest then earth would
freeze because sunlight wouldn't be able
to reach its increased surface area
it seems that all iterations of the
flatter theory end up with the
destruction of our planet and everything
in it
shouldn't the fact that we're alive then
be proof enough that the earth is round
in theory it should but facts don't
change minds i made an entire video
about this if you want to check it out
link is in the description but the truth
is that humans have known for a very
long time that the earth is in fact round
round
around 500 bce pythagoras first proposed
that the earth is spherical while his
findings were not based on any physical evidence
evidence
he believed along with many greeks after
him that a spherical shape simply made
the most sense
over a century later aristotle was the
first to provide empirical evidence of
earth's surrounding shape listing many
arguments such as ship's disappearing
hall first when they sail over the horizon
horizon
earth found shadow on the moon during a
lunar eclipse and different
constellations being visible at
different latitudes
the greeks believed so much that our
planet was round even in times with very
limited technology that they went as far
as measuring out its size
in 276 bce eratosthenes discovered that
the earth's circumference to be 40 250
to 45 900 kilometers or 25 000 to 28 000 miles
miles
simply by using the shadow of a stick to
measure the angular displacement of the
sun in two different locations
he then multiplied the angle by the
distance between the two locations and
gave us our first estimation of the size
of the planet
and the thing is he wasn't that far off
earth's actual circumference is 40 070
kilometers or 24 901 miles
if you're wondering we measured it using
an orbiting spacecraft
apart from being such an astonishing feat
feat
measuring the earth using the angular
displacement of the sun in two locations
was also another piece of evidence to
prove that the earth is spherical
on a flat plane the shadow cast by the
sun would be the same length everywhere
it's only because of the earth's
curvature that the sun can shine on one
part of the earth at one angle and on
another part of the earth at a different
angle causing one shadow to seem longer
than the other
following the greeks islamic scholars
made further advancements in the 9th
century then european navigators circled
the globe in the 16th
finally in the 20th century we sent
spacecraft satellites and probes into space
space
all of which brought back astonishing
images of our big blue planet
time and time again through different
pieces of research done by various
communities around the world who don't
agree on a lot of things
we've proven empirically mathematically
and scientifically that this little rock
we all call home
is around [Music]
[Music]
but if we're being honest it was never
really about the evidence
believing in a flat earth is a form of
science denial where people entirely
question the main premise behind
scientific ideas
science denial is usually linked to a
conspiracy mentality that makes people
susceptible to wrong ideologies about
all things science
what all these people have in common is
the denial in the scientific process and
are discussed for organized institutions
like governments and research agencies
while believing in a flat earth doesn't
seem to be as harmful as not believing
in climate change for example
conspiracy theories in general become
dangerous when they gather a large following
following
so large that they start to affect some
changes in the policies and decisions of
a society
lee mcintyre a philosopher from boston
university and an expert on science denial
denial
believes that if these misguided ideas
aren't challenged proponents of a flat
earth will start running for u.s school
boards looking to push their ideas into
the u.s education system
because conspiracy theorists are
generally highly skeptical people who
have lost their trust and authority
while we understand that facts don't
always change minds
perhaps instead of arguing the evidence
for a spherical earth a better approach
would be to help these people
reestablish their trust in science
make it about the emotion instead of the
facts because even in face of
overwhelming counter evidence
people are most likely to cling to their beliefs
beliefs
instead of patronizing flat earth
proponents science needs to take their
questions seriously and answer them
patiently and with the level of
sustained engagement
flat earthers may distrust science today
but approaching their uncertainties with
a lower level of scrutiny could help
against the spread of misinformation and
deceptive claims
be that as it may there's still a
special appeal to the flat earth theory
not because it holds any scientific
merit but simply because it allows us to
imagine how unforgiving the universe
could be if the conditions were any different
different
are planets uniquely built to sustain
millions of life forms and its spherical
shape is essential to our survival
this is the most famous image taken of
our planet it's called earthrise and it
changed our relationship with our home forever
forever
while earlier spacecraft had taken
images of earth this is the first one
taken by an awestruck astronaut holding
a camera
when william anders took this picture
from the moon's orbit in 1968 he offered
us a one-of-a-kind glimpse at the rock
we all call home in its place in the
cold dark universe
it's almost as if humanity was able to
look itself in the mirror for the first time
time
take a deeper look at this image
right now all of us are somewhere on
this little blue ball half submerged in
darkness quietly floating in empty space
we have a protective atmosphere to
shield us from the harmful rays of the
sun breathable air and oceans of water
integral to our survival
the sun gives us light and energy and
gravity keeps us rotating at a safe
distance from it
this tiny blue ball floating in the
darkness of space right now seems to be
the only place in the observable
universe with just the perfect
conditions to spawn life
so no
earth isn't flat
today's video was sponsored by brilliant
one of the best places online to learn
anything in everything stem related
in today's video we talked about how
when trying to disprove a conspiracy
theory it's not really the evidence that
matters but the trust in that evidence
to build trust in the scientific
community and the evidence they provide
the best thing we can do is to teach
science technology engineering and math
courses in a way that's not intimidating
to people
this is why i'd love brilliant brilliant
is an amazing tool to learn these stem
courses interactively with courses like
scientific thinking brilliant doesn't
just teach you theory they help you
understand how these theories affect our
daily lives
