This is a video by RealLifeLore
sponsored by The Great Courses Plus.
A little over three months ago,
I released a video about what if everybody on earth lives inside the same city.
Today we're going to talk about something perhaps even more terrifying -
What if everybody on earth lives inside the same building
How large with this building have to be to house all 7.4 billion of us survive right now?
It's not a strange of a question as it may seem at first.
This picture right here is the town of Whittier, Alaska.
And by that I mean the entire town is located inside of this one building
The entire city's population of two hundred fourteen people for the most part lives inside this single building.
And they really don't have to ever leave it.
This is because almost all of the functions that you would normally find inside of a city are all located inside of the building.
Inside, you can find the city's police department,
The post office,
The mayor's office,
A general store,
A grocery store,
A hospital,
A laundromat,
A hotel,
A church in the basement,
And even an indoor playground complete with a swimming pool.
The building is the city and the residents of the city can stay indoors almost indefinitely whenever the weather begins to get bad,
Because all of the city services as well as their homes are all located inside of it.
But even still just 214 people live here which is nowhere near the entire human race.
So let's get bigger and think about buildings with the largest seating capacity.
The AT&T stadium in Arlington, Texas is the home of the Dallas Cowboys and is truly enormous,
Larger than the US Capitol building and capable of sitting 80,000 people.
Which means that you can comfortably seat the entire population of Andorra inside of it
But it still isn't as big as the largest indoor stadium in the world
which is located here in Pyongyong North Korea and it's
called Rungrado 1st of May Stadium..
It has the capacity to seat 114,000 people
all indoors 34,000 more people than the
AT&T stadium or about the same
population as the Island of Kiribati or
about twenty percent of the population
of Wyoming but even that isn't as big as
the largest ever planned Indoor Stadium
which would have been constructed in
Berlin by Nazi Germany had they won the
Second World War the building would have
been called the Volkshalle and would
have been capable of sitting 180,000
people inside about five percent of the
population of modern-day Berlin the
building would have been so enormous
that German architects calculated that
the moisture collected by all of these
people breathing inside of it could have
actually created artificial rain and
side causing the building to have its
own weather if we move to outdoor
stadiums however which would still be
one building in a sense and we can fit
much more people the largest outdoor
stadium currently is the Indianapolis
Motor Speedway capable of seating
235,000 people a little less than the
entire population of reno nevada but
once again the Nazis had plans for an
even larger stadium in the event of a
victory in World War Two their plans
were to construct the Deutsche Stadion on
in Nuremberg which would have been
capable of feeding a massive 405,000
people more than the population of New
Orleans and over five times the seating
capacity of the AT&T Stadium Hitler
plans that after Germany won World War
Two every single Olympic Games for the
rest of history would take place here at
this stadium but because the war was
lost the stadium was never finished
however the largest building anywhere in
the world in terms of how many people
are meant to fit inside of it would be
the Great Mosque in Mecca Saudi Arabia
during the Hajj period the mosque has
the capacity to fit four million people
inside of it which is greater than the
entire population of Panama there are
buildings that could in theory fit more
people to miss though they're not
designed to fit people but we're going
to see what could happen if we did so
anyway before we get started with this
part though let's figure out how many
people we could safely bit inside of one
square meter after a lot of research it
seems that anything over five people
first where meter to be potentially
dangerous and lead to people trampling
each other so that the highest limit
let's go with about five people on
average being able to possibly fit into
one square meter the largest building in
the world in terms of its physical
footprint on the earth's surface is
going to be the Tesla gigafactory once
it's finished being built in Nevada its
gargantuan when compared to the AT&T
stadium and the US Capitol building and
it would take up a physical state of
530,000 square
meters or a little larger than vatican
city which means that you could fit the
world's smallest country completely
inside of the boundaries of the world's
largest building at five people per
square meter that means you can fit
2,650,000 people inside the building all
indoors more people to live in all of
namibia so we're at the scale of entire
countries worth of people sitting inside
one building out but we can still get
much larger the largest building ever
designed in terms of the floor space
that would occupy with the Crystal
Island building which would have been
built in Moscow where it not halted have
been completed it would possess two and
a half million square meters were the
floor space which combined could have
fit a staggering 12 million five hundred
thousand people were more than the
entire population of Belgium but we can
still go even bigger if we begin to take
a three-dimensional view rather than the
two-dimensional view that we've had so
far with this in mind the average height
for a modern human is roughly 1.63 meters
therefore if we construct a cube with a
one square meter base and height of 1.63 meters and we can fit five average
human inside of it
this gives us 0.326 cubic metres per
person for 3.07 people per cubic meter
with this mouth in mind the largest
building in the world in terms of sheer
volume is the Boeing Everett factory
located in Washington the building
possesses 13.3 million cubic meters
located entirely indoors which is so
large that the building has its own
microclimate somewhat similar to what
the proposed Volkshalle in Berlin would have been like adding floors into the
building with an average height of just
1.63 meters each capable of fitting the average human
inside and we could theoretically fit 40,831,000 people inside of here
which would be enough to fit the entire
populations of Denmark Norway Sweden
Finland Iceland Greenland Estonia Latvia
and Lithuania all combined and still
have room left over for all of Serbia
just for good measure
that's the largest building in the world
though and that's still not even one
percent of the entire human population
that could possibly fit inside of it to
get to that point we need to construct a
new building and if we did so what is
the smallest possible size that it could
be to fit all of us
well at the time of making this video
the world population is
actually 7.4 78 billion people if we
crammed people into the same density as
we did inside the boeing factory and we
will require a volume of 2.436 billion
cubic meters or 2.436 cubic kilometers
the building would be a cube with sides
of 1.3 for six kilometers in length and
height of 1346 meters this seems big but
place in downtown New York City that
would actually look like this inside of
which you can actually fit every single
human being alive today the tallest
building in the world is the Burj
Khalifa at nearly 800 30 meters high but
the tallest building under construction
that will be done in 2020 is the jetta
tower which will be much higher when
finished at 1080p ters only 330 meters
short of our mega cube the base of the
cube would only be about five times
larger than the Tesla gigafactory as
well so building the cube is certainly
within the realm of possibility and if
it was built the entire human race alive
today all 7,478,000,000 of us could
also fill inside of a building that would
only take around half an hour to jog
around so thank you very much for
