When we are born we have a very small view of the world: our mother’s womb and the
delivery room.
And, as you’re raised, your parents are probably trying to control the environment
that you’re in and so you end up with a very centralized, tiny little view of the
world—naturally.
As you get older, as you travel more, as you read more, you start to understand a little
more of the world around you; and all of those influences affect your choices in life.
What are you going to imagine that you could be?
If you’ve never left Main Street, small town, Ohio, then you’re probably not going
to visualize yourself doing something that is wildly different than that.
You’re never going to be the head of a religious sect in Pakistan; it’s not inside your worldview.
You can only draw your own aspirations and hopes and decisions based on the things that
you even know exist.
It’s easier now to understand and see the world than ever in history.
Our ability to communicate and our ability to travel has greatly improved.
But space travel is sort of like the wildly exaggerated version of that, where you can
go around the whole world in the time it takes to eat supper, and see everywhere, see the
whole world 16 times a day.
That widens and deepens your worldview like nothing we’ve ever seen before in history.
And it’s very difficult to maintain artificially drawn biases like nationalistic borders and
“my little tribe”, “my little street”, “my little gang”, “my little town”,
my little whatever when, 15 minutes later, you’re over at the exact same-looking sort
of town—but it’s in Africa, and 40 minutes later the exact same-looking sort of town
and it’s in Australia—and then you come up to Indonesia—and you go, “Man, it’s
all the same.
They build their towns just like we build our towns, and how are they “They” then?
It’s just sort of all “Us”.
We’re all doing this thing together, and everyone has got the same sort of hopes and
dreams amongst themselves.
And that pervasive sense of the shared collective experience of being a human being, that seeps
into you onboard a spaceship.
Not the first time around.
The first time is overwhelming, but somewhere, you know, a hundred times around, 500 times
around, suddenly the world becomes one place in your mind.
It’s not very big, and that I think is a really important worldview to have.
Life can be full of magnificent experiences.
Being at the wedding of a loved one in a beautiful, big house of worship somewhere where there’s
the sound and the beauty and the structure—it affects how you feel that day, and you act
a little bit differently.
Or walking into a gigantic ancient redwood forest, your head is naturally drawn upwards
and you think a little different.
It’s not the same as just walking down your street.
Imagine what it’s like on a spaceship, where you’re floating weightless at a window,
where you see an entire continent in the time it takes to drink a cup of coffee, where you
go from L.A. to New York in nine minutes and you see all of that history and culture and
climate and geography and geology, and it’s all right there underneath you.
And you see a sunrise or a sunset every 45 minutes; you see the world for what it actually
is.
It has that same sort of personal effect on you, of a feeling of privilege and sort of
a reverence, an awe that is pervasive.
When we’re floating in the bulging window, the Cupola of the space station—normally
it’s just one person because everybody is busy, but if there is two of you in there—you
talk in hushed tones to each other just because you feel like you’re just wildly lucky to
even be there to see this happening.
And that sense of wonder and privilege and clarity of the world slowly shifts your view,
of course.
Your understanding of what is “us” and what is “them”; what is old and what is
new; what does four billion years actually mean?
You can see where the ice ages were, you can see where the volcanoes were and the huge
asteroid impacts and such, and it all starts to shift in your head.
There was a fellow in the late-'60s, early-'70s who wrote a book trying to capture that.
He called it 'the overview effect'.
You can call it whatever you like.
It doesn’t have to be involved with spaceflight.
It’s more when you sense that there is something so much bigger than you, so much more deep
than you are, ancient, has sort of a natural importance that dwarfs your own—but you’re
a person seeing it, you’re a person that’s interpreting it, you’re understanding it
in your own way, and you’d have to be a stone to not have that effect you.
It changes how you think about things.
But it’s not the same for everybody, and it’s not instantaneous, it’s not like,
“Hey I’ve gone over 60 miles an hour now, I’ve done this thing.”
it’s very much a gradual, creeping improvement in perception of the world around us.
I think that’s what the author was trying to talk about when he wrote about the overview
effect.
And some people are much more emotive and it affects them very deeply; some people,
they just have a better understanding of the world itself.
Either way, it’s healthy.
It’s a perspective of the world that allows us, hopefully, to make better collective,
global decisions about what’s happening—less jealous, narrow, local decisions.
And we need that type of thinking if we’re truly going to have this many people and this
standard of living for the foreseeable future.
We just need to see the world as one place, the fact that we’re all in this together,
and that we are in the position to actually understand it and appreciate it and therefore
make different decisions about it.
