12,000 years ago in the hills of Modern-day turkey our ancient ancestors built
What is to our knowledge the oldest temple in the world?
It has always been a human desire to see how far up into the sky their creations can reach
ancient humans used to gaze up at the night sky
and dream about reaching the stars with their buildings it is only natural for
Humanity to push further than ever before and to build taller and taller than anybody before them
But surely there must be a limit to how tall we can eventually build something, right?
What is actually the tallest thing that we could theoretically ever build?
to begin with a sense of scale
This is a standard height for a one-story family home about four and a half meters tall above the ground moving up from there at
128 meters High is the tallest statue in the world a statue, so
Tall that if you jumped from the top of its head it would take you five and a half seconds before hitting the ground
just a bit higher at
139 meters is the tallest Roller coaster in the world
But that's not quite as high up as the great pyramid of giza which was built a very long time ago in
2500 70 BC
once completed it was by far the tallest thing that we humans had ever built and it maintained that record for an
unbelievable three thousand eight hundred Eighty-one years
until it was finally beaten in the year thirteen Eleven in England the Lincoln cathedral reached a soaring height of
160 meters into the sky and that remained the tallest thing that humans had ever achieved until kind of recently in
1884 when the Washington monument in Washington DC. Finally surpassed its height at
169 meters the tallest Ferris wheel in the world Currently is Roughly the same height as this
Monument, so the monument clearly didn't remain the tallest structure for very long the Eiffel tower
Surpassed it quickly and was 301 meters high above the ground which
Absolutely dwarfed everything that humans had ever built before it the Eiffel tower
Kind of opened up Pandora's box though in terms of how tall we could possibly build something with the advent of wrought iron
and steel the height of our structures could get much greater the Chrysler building at
319 meters tall finally unseated the Eiffel tower after 41 years of holding the record
but the very next year after it was completed the Empire state building stole the crown at a massive height of
448 meters
but even this record wouldn't last for very long because starting in 1963 the tallest thing ever built by
Humanity would actually be a TV mast
the tallest of these ever built was the Warsaw radio tower which ascended to a staggering height of
646 meters it collapsed in 1991 but its height was never surpassed until very recently in
2008 to prepare for the scale of the tallest thing ever built by Humans so far
I'm going to include Several other very tall and recognizable buildings onto this graph first
But by far taller than any of them is the Burj Khalifa in Dubai
this Monster Building is
830 meters tall it takes two thousand nine hundred and nine steps to walk up from the ground floor to the top
Or you can take an elevator ride that takes two minutes and 40 seconds?
If you jump from the top and somehow hits the ground without hitting any part of the building it would take you 20
Seconds to fall the entire distance go ahead and start a timer at 20 seconds to understand how long of a fall that
actually is but the burj Khalifa is only how tall we have built not how tall we possibly could build if
We wanted to we could build something
significantly higher so what's preventing us from doing that right now in
theory there really isn't a limits to how tall we could build something at all so long as we kept expanding the base of the
Structure to support the added weight on the top
since the Earth is spherical there obviously is a limit to how much we could expand the base of the structure by
So given our current technology and resources the tallest thing we could possibly build right now is likely the exeed
4000 the tallest structure ever fully envisioned with completed blueprints it would soar to an insane height of four
Kilometres into the sky which would make the burj kalifa look puny in comparison
And it would be even taller than Mount Fuji is in Japan it would even reach about
45% as high as mount everest or
2748 Toyota Corollas stacked on top of each other the base of the tower would have to be six
kilometres across in order to support the
enormous weight on the top
It would basically be a metal mountain capable of housing over 1 million people inside of it, and it would be so
Gargantuan that it would likely
disrupt weather patterns around wherever it is built the cost of building such a titanic structure however is perhaps as equal a
Ludicrous thought Estimates range anywhere from
479 Billion Dollars on the lower end up to one point four Trillion dollars on the higher end
Which is higher than the entire GDP of Russia the XC?
4000 is a true testament to possibility and if we decided to build it today?
There's nothing that could stop us from finishing it tomorrow in the future it may become possible to build even more outrageous
structures like a space elevator
100,000 kilometers above the Earth's surface
But since that currently isn't possible
I decided to leave it out of this video until now
There doesn't exist a material that we can produce enough of that is both strong and light enough to build a space elevator
But if our technology advances enough in the future it is
Theoretically possible to build which makes this probably the tallest thing that could ever be built on Earth in humanity's future
for some perspective the international space station only orbits around the Earth this far away from the surface while the
100,000 kilometer space elevator would stretch all the way out to here
Due to the Earth's rotation the top of this elevator would be moving incredibly fast relative
To the surface this means that people on board would experience a modest amount of time dilation
similar to what astronauts onboard the International space station
Experienced today astronaut Scott Kelly for example spent an entire year
Aboard the space station and as a result of time dilation. He returned back to Earth
0.01 seconds younger than his identical twin brother it may not seem like much
But Scott kelly in effect time traveled a very small amount due to the speed that he was traveling
at I learned a lot about time travel and how it could be possible just
Yesterday in a few spare minutes by listening to blink asst a new digital learning app that distills the key insights behind great
