The world seems like it’s becoming a smaller and smaller place all the time.
As technology has improved,
the ability to travel around the world has gotten more and more easy to do.
With that being said though,
if you were absolutely determined to make a full circumnavigation around the planet today,
what is the quickest time that you could possibly do it in?
For a little bit of reference,
let’s go back to the first time that anybody successfully did that.
The men aboard Ferdinand Magellan’s voyage back in 1519
being a part of this voyage really truly sucked.
They started with 5 ships and 270 men,
and took over 3 years to complete the trip.
Magellan himself got killed in the Philippines along the way.
And out of those 270 guys,
only 18 of them managed to actually survive the journey back to Spain.
Travelling around the world was a truly terrifying feat to attempt then,
and still was for a long time.
Everybody who tried it took somewhere between 2 to 3 years up until the 19th century.
The first ship that got really close to circumnavigating the world and under a year
was a Confederate ship basically on accident during the US Civil War.
The CSS Shenandoah left London to raid Union shipping lines across the world,
and wanting to avoid piracy charges after the war ended.
The crew sailed back to London to surrender to the British instead
twelve and a half months after first departing from there.
Building canals later in the Suez and Panama
enabled people to not have to sail around the entire continents of Africa and South America,
which allowed for much quicker travel times.
As of the making of this video,
the fastest that anybody has circumnavigated the world in a boat so far
was just last year in 2017.
Frances Joy Yon 以及5个船员
Frances Joy Yon, along with a crew of 5 sailors, managed to sail around the world
in just 40 days, 23 hours, 30 minutes and 30 seconds.
But sailing is slow when compared to flying.
So, how quick can you get around while in the air?
The first time anybody flew around the world happened back in 1924 by the US Army Air Service.
And it took them 175 full days to complete, which is ludicrously slow.
But it was still faster than any other alternative was at the time.
Just a few years later though in 1929,
that time was drastically improved by Zeppelin piloted by Hugo Eckener,
managed to get around the world in a brisk 21 days.
2 years later in 1931,
2 pilots flying a Lockheed Vega smashed that record
by flying around the world in just 8 days, 15 hours and 51 minutes.
Progress on getting this time down further continued through 1949,
when the US Air Force flying a B50 superfortress made the first flight around the world
without stopping to refuel.
Relying instead on midair refuelings,
the plane managed to fly around the world in just 94 hours and 1 minute.
This was the first time that humans managed to travel around the world in less than a week.
So now, we can fully appreciate how easy and fast this is in the modern world.
Air France flying the Concorde set the all-time record for the fastest time
circumnavigating the world in a sub-orbital flight all the way back in 1992.
They managed to get around the entire planet in just 32 hours, 49 minutes and 3 seconds,
over 800 times faster than Magellan’s first voyage was in 1519.
Nobody, even now, has managed to travel around the world in under a day without having gone to space.
Going to space, though, changes both the rules and the times that are possible by a dramatic amount.
If you’re to believe Elon Musk’s claims about what SpaceX’s new rocket,
the interplanetary transport system will be capable of.
It should be able to transport anybody on earth from one place to any other place in under one hour.
If you watch the video that they uploaded to their YouTube channel,
they claim that a flight from New York City to Shanghai will only take 39 minutes while on board.
If we accept the claim that the rocket can get from one side of the earth to the other in under an hour,
then it should be reasonable to assume that it could fully circumnavigate the world in under two hours.
That’s really fast.
But there are already people who have done it faster.
This guy, Yuri Gagarin, became the first human in space back in 1961,
and completed his first full orbit of the earth in just a tiny 108 minutes.
But the astronauts onboard the International Space Station can do even better.
The ISS makes a complete orbit around the earth once every 92 minutes,
which if you can afford the 20 to 40 million dollar price tag to take a trip up
is the fastest way that you can move your body around the earth.
There are some satellites and aerial that can orbit the earth quicker in 84 minutes.
所以 你可以把自己绑在某一个上面 然后开始你的旅程
So, you could possibly strap yourself onto one and ride it out.
You’d probably die, of course.
But nothing in the rules said that you need it to be alive to complete it.
So, there you have it:
92 minutes if you want to stay alive,
and 84 minutes if you don’t.
Or, if you want to settle for traveling in a plane,
just hope that the Concorde comes back, and do it in about 32 hours.
Of course, if you’re like me though,
and waiting for anything for any amount of time bores you into oblivion,
why not do something productive next and try out SKILLSHARE?
SKILLSHARE has over 19,000 classes
on anything from Python programming to 1930’s Character Design illustrations.
If there’s any skill you want to learn,
then there’s a good chance that SKILLSHARE has a class for it.
The most frequent email that I get from you guys
is how to start learning animations to create your own videos on your own channels.
So, if you want to learn today,
they have a course on animation taught by the senior motion graphics designer of KURZGESAGT.
然而 最大的看点是 你不用花很多的钱去学习
The greatest news about this, though, is that you don’t need to spend much to start learning.
