Ray Bradbury’s Unpublished Poems and His Meditation on Science vs. Religion

By:

“It is a small thing, this dear gift of life handed us mysteriously out of immensity.”

We recently took a trip back to the day before NASA’s Mariner 9 mission reached Mars in 1971, when Carl Sagan, Arthur C. Clarke, and Ray Bradbury — whom we lost just a few short months ago — joined New York Times science editor Walter Sullivan in a remarkably prescient conversation about Mars and future of space exploration, later released as Mars and the Mind of Man (public library). Among the day’s many gems were three unpublished poems by Ray Bradbury, which he shared with the audience, alongside a poignant meditation on science vs. religion — a subject we have far from put to rest since:

In the last few years, I have found myself returning again and again to the problem of science and theology. This problem has thrust itself into the center of a series of poems I have written. I have for some time now thought that the conflict between religion and science was a false one, based, more often than not, on semantics. For when all is said and done, we each share the mystery. We live with the miraculous and try to interpret it with our data correctors or our faith healers. In the end, survival is the name of the game.

One upon a time we created religions which promise us futures when we knew there were no possible ones. Death stared us in the face, forever and ever.

Now, suddenly, the Space Age gives us a chance to exist for a billion or two billion years, to go out an dbuild a heaven instead of promising one to ourselves, with archangelic hosts, saints waiting at Gates, and God pontifical on his Throne.

This second* poem of mine is titled ‘Old Ahab’s Friend and Friend to Noah Speaks His Piece.’ It is written from the viewpoint of the whale speaking to future men, telling them they must build a whale and live inside it and go out into space in it and travel through time to survive forever. Here is the conclusion of the poem:

I am the Ark of Lie. You be the same!

Build you a fiery whale all white.

Give it my name.

Ship with Leviathan for forty years

Until an isle in Space looms up to match your dreams,

And land you there triumphant with your flesh

Which works in yeasts, makes wild ferment,

Survives and feeds

On metal schemes.

Step forth and husband soil as yet untitled,

Blood it with your wives, sow it with seeds,

Crop-harvest it with sons and maiden daughters,

And all that was begat once long ago in Earth’s strange waters

Do recall.

The White Whale was the ancient Ark.

You be the New.

Forty days, forty years, forty-hundred years,

Give it no mind;

You see. The Universe is blind.

You touch. The Abyss does not feel.

You hear. The Void is dear.

Your wife is pomegranate. The stars are lifeless and bereft.

You smell the Wind of Being.

On windless worlds the nostrils of old Time are stuffed

With dust and worse than dust.

Settle it with your lust, shape it with your seeing,

Rain it with your sperming seed,

Water it with your passion,

Show it your need.

Soon or late,

Your mad example may imitate.

And gone and flown and landed there is White Whale craft,

Remember Moby here, this dream, this time which does suspire,

This kindling of your tiny apehood’s fire.

I kept you well. I languish and I die.

My bones will timber out fresh dreams,

My words will leap like fish in new trout streams

Gone up the hill of Universe to spawn.

Swim o’er to stars now, spawning man,

And couple rock, and break forth flocks of children on the plains

On nameless planets which will now have names;

Those names are ours to give or take.

We out of Nothing make a destiny,

With one name over all

Which is this Whale’s, all White.

I you begat.

Speak then of Moby Dick,

Tremendous Moby, friend of Noah.

Go Go now.

Ten trillion miles away,

Ten light-years off,

See from your whale-shaped craft;

That glorious planet!

Call it Ararat.

(The poetic picture of the phoenix-whale Bradbury paints is reminiscent of the beautiful Whale Fall cut-paper animated short for Radiolab.)

* Bradbury shared another poem, which remains his best-known, earlier in the discussion:

IF ONLY WE HAD TALLER BEEN

O, Thomas, will a Race one day stand really tall
Across the Void, across the Universe and all?
And, measure out with rocket fire,
At last put Adam’s finger forth
As on the Sistine Ceiling,
And God’s great hand come down the other way
To measure Man and find him Good,
And Gift him with Forever’s Day?
I work for that.
Short man. Large dream. I send my rockets forth
between my ears,
Hoping an inch of Will is worth a pound of years.
Aching to hear a voice cry back along the universal Mall:
We’ve reached Alpha Centauri!
We’re tall, O God, we’re tall!

Lastly, in the “Afterthoughts” section of the book, in which the panelists revisit the subject a year after the Mars mission, Bradbury shares one final poem, touching once again on the subject of the mysterious:

THAT IS OUR EDEN’S SPRING, ONCE PROMISED

What I to apeman
And what then he to me?
I an apeman one day soon will seem to be
To those who, after us, look back from Mars
And they, in turn, mere beasts will seem
To those who reach the stars;
So apemen all, in cave, in frail tract-house,
On Moon, Red Planet, or some other place;
Yet similar dream, same heart, same soul,
Same blood, same face,
Rare beastmen all who move to save and place their pyres
From cavern mouth to world to interstellar fires.
We are the all, the universe, the one,
As such our fragile destiny is only now begun.
Our dreams then, are they grand or mad, depraved?
Do we say yes to Kazantzakis whose wild soul said:
God cries out to be saved?
Well then, we go to save Him, that seems sure,
With flesh and bone not strong, and heart not pure,
All maze and paradox our blood,
More lost than found,
We go to marry stranger flesh on some far burial ground
Where yet we will survive and, laughing, look on back
To where we started on a blind and frightful track
But made it through, and for no reason
Save it must be made, to rest us under trees
On planets in such galaxies as toss and lean
A most peculiar shade,
And sleep awhile, for some few million years,
To rise again, fresh washed in vernal rain
That is our Eden’s spring once promised,
Now repromised, to bring Lazarus
And our abiding legions forth,
Stoke new lamps with ancient funeral loam
To light cold abyss hearths for astronauts to hie them home
On highways vast and long and broad,
Thus saving what? Who’ll say salvation’s sum?
Why, thee and me, and they and them, and us and we…

And God.

He concludes with this exquisite meditation on mankind’s timeless quest for immortality. (Which leads one to wonder whether today’s singularity set is any different from history’s religious cults, grasping at promised lands underpinned by little more than the very human and very vulnerable fear of mortality, of ceasing to exist and refusing to believe in nonexistence.)

The universe is full of matter and force. Yet in all that force, amongst all the bulks and gravities, the rains of cosmic light, the bombardments of energy — how little spirit, how small the decimal points of intelligence.

Dumb, sometimes — yes. Awful, quite often. Dreadful apish brutes on occasion following occasion. That’s how we things that represent intelligence seem to ourselves, and quote often truly are.

And yet I would not see our candle blown out in the wind. It is a small thing, this dear gift of life handed us mysteriously out of immensity. I would not have that gift expire. Crossing the wilderness, centuries ago, men carried in covered cows’ horns the coals of the previous nights’ fires to start new fires on the nights ahead. Thus we carry ourselves in the universal wilderness and blow upon the coals and kindle new lives and move on yet once more.

[…]

Why, sweet Jesus, what’s the use of looking at Mars through a telescope, sitting on panels, writing books, if it isn’t to guarantee, not just the survival of mankind, but mankind surviving forever! Good God in heaven, we were born to live, and live in mystery, which crowds all about and would smother us if we let it.

[…]

Some of you will immediately say we go to pollute Mars. You are the people who see a partially filled glass as half empty.
I see the glass as half full.
I say we go to save Mars from itself.
And do ourselves favors, meanwhile.

Paradoxically stated: what is not polluted is elevated. I live inside the last word.

Hear Bradbury read in this short excerpt from the panel:

More than three decades later, Bradbury revisited the subject of space exploration in this rare 2003 audio interview.

Complement with Bradbury on doing what you love — some of the best life-advice you’ll ever receive.

Mars and the Mind of Man: Carl Sagan, Ray Bradbury and Arthur C. Clarke in Cosmic Conversation, 1971

By:

“It’s part of the nature of man to start with romance and build to a reality.”

On November 12, 1971, the day before NASA’s Mariner 9 mission reached Mars and became the first spacecraft to orbit another planet, Caltech Planetary Science professor Bruce Murray summoned a formidable panel of thinkers to discuss the implications of the historic event. Murray himself was to join the great Carl Sagan and science fiction icons Ray Bradbury and Arthur C. Clarke in a conversation moderated by New York Times science editor Walter Sullivan, who had been assigned to cover Mariner 9’s arrival for the newspaper. What unfolded — easily history’s only redeeming manifestation of the panel format — was a fascinating quilt of perspectives not only on the Mariner 9 mission itself, or even just Mars, but on the relationship between mankind and the cosmos, the importance of space exploration, and the future of our civilization. Two years later, the record of this epic conversation was released in Mars and the Mind of Man (public library), alongside early images of Mars taken by Mariner 9 and a selection of “afterthoughts” by the panelists, looking back on the historic achievement.

Arthur C. Clarke — who, in a 1945 article entitled “Extraterrestrial Relays” had proposed communications satellites long before they became an active government project and who had previously predicted the techno-future in general and even the iPad in particular with astounding accuracy — offers a prediction regarding Mars that is, ultimately, inaccurate but wrapped around it is an insightful and timely meditation on the larger subject at stake:

We are now in a very interesting historic moment with regard to Mars. I’m not going to make any definite predictions because it would be very foolish to go out on a limb, but whatever happens, whatever discoveries are made in the next few days or weeks or months, the frontier of our knowledge is moving inevitably outward.

It has already embraced the Moon. We still have a great deal to learn about the Moon and there will be many surprises even there, I’m sure. But the frontier is moving on and our viewpoint is changing with it. We’re discovering, and this is a big surprise, that the Moon, and I believe Mars, and parts of Mercury, and especially space itself, are essentially benign environments — to our technology, not necessarily to organic life. Certainly benign as compared to the Antarctic or the oceanic abyss, where we have already been. This is an idea which the public still hasn’t got yet, but it’s a fact.

I think the biological frontier may very well move past Mars out to Jupiter, which I think is where the action is. Carl, you’ve gone on the record as saying that Jupiter may be a more hospitable home for life than any other place, including Earth itself. It would be very exciting if this turns out to be true.

I will end by making one prediction. Whether or not there is life on Mars now, there will be by the end of this century.

Following Clarke is Carl Sagan, who does what he does best in discussing the issue of how rigorous we need to be in sterilizing spacecraft that makes contact with other planets — taking a scientific particularity, linking it to the universally human, then circling back to the science having engendered a whole new understanding of its context:

We can be emotionally predisposed as pessimists as well as optimists. Actuarial procedures provide a guide to situations of this sort. How careful you have to be in a given situation and how much premium you have to pay is not only a question of how likely the event in question is but also how important the event is. Suppose, for example, we’re concerned about carrying terrestrial microorganisms to Mars, depositing them there, and having them survive and multiply so that the next generation of space vehicles finds the next generation of microbes. How do we then distinguish Earth’s life from Mars life?

He follows that with one of the most eloquent portions of the entire conversation — an insistence on the value of embracing ignorance, learning to live with ambiguity, and choosing the unknown over answers that might be wrong, alongside a call for balancing skepticism with openness — something he’d articulate formally more than a decade later:

Is it possible that there is life on Mars, Martians? Now, just as there have clearly been excesses in the direction of prematurely concluding that there is life on Mars … there have also been excesses in the other direction, in prematurely concluding there isn’t life on Mars. We have a certain intolerance for ambiguity, saying, ‘Don’t confuse me with the facts, just give me an answer.’ Well, I think that’s where we are on the question of life on Mars. There is, as far as I can tell, no more reason to conclude that Mars is lifeless than there is to conclude that it is inhabited. There is water, there is carbon dioxide, there is sunlight — these are the prerequisites even for parochial forms of green plant photosynthesis.

He echoes the same sentiment a few minutes later, in an insight that applies to the Mariner 9 mission as much as it applies to all of life:

I think the proper attitude is to keep an open mind and see what the observations uncover.

But by far the most beautiful meditation comes from Ray Bradbury, who transposes his passionate advocacy of writing with joy and excitement onto space exploration as well:

I think it’s part of the nature of man to start with romance and build to a reality. There’s hardly a scientist or an astronaut I’ve met who wasn’t beholden to some romantic before him who led him to doing something in life.

I think it’s so important to be excited about life. In order to get the facts we have to be excited to go out and get them, and there’s only one way to do that — through romance. We need this thing which makes us sit bolt upright when we are nine or ten and say, ‘I want to go out and devour the world, I want to do these things.’ The only way you start like that is with this kind of thing we are talking about today. We may reject it later, we may give it up, but we move on to other romances then. We find, we push the edge of science forward, and I think we romance on beyond that into the universe ever beyond. We’re talking not about Alpha Centauri. We’re talking of light-years. We have sitting here on the stage a person who has made the film* with the greatest metaphor for the coming billion years. That film is going to romance generations to come and will excite the people to do the work so that we can live forever. That’s what it’s all about. So we start with the small romances that turn out to be of no use. We put these tools aside to get another romantic tool. We want to love life, to be excited by the challenge, to life at the top of our enthusiasm. The process enables us to gather more information. Darwin was the kind of romantic who could stand in the middle of a meadow like a statue for eight hours on end and let the bees buzz in and out of his ear. A fantastic statue standing there in the middle of nature, and all the foxes wandering by and wondering what the hell he was doing there, and they sort of looked at each other and examined the wisdom in each other’s eyes. But this is a romantic man — when you think of any scientist in history, he was a romancer of reality.

Arthur C. Clarke follows up with a crucial point about science and whimsy — something Richard Feynman would articulate in uncannily similar phrasing exactly a decade later in his famous words from The Pleasure of Finding Things Out:

There are some not-very-bright and/or badly educated people who complain, with apparent sincerity, that scientific research destroys the wonders and magic of nature. One can imagine the indignant reaction of such poets as Tennyson or Shelley to this nonsense, and surely it is better to know the truth than to dabble in delusions, however charming they may be. Almost invariably, the truth turns out to be far more strange and wonderful than the wildest fantasy. The great J. B. S. Haldane put it very well when he said: ‘The universe is not only queerer than we imagine — it is queerer than we can imagine.’

Reflecting upon the unprecedented amount of imaging data that Mariner 9 promised to provide, Sagan captures the strange tension of exploration and ignorance, all the timelier as NASA’s Curiosity has pushed us to make sense of a new precipice of knowledge today:

Now we have moved from a data-poor, theory-rich situation to one that is data-rich, theory-poor.

In the “Afterthoughts” section, Sagan makes a case Neil deGrasse Tyson has passionately echoed four decades later:

[Space exploration] is in financial trouble. Yet by many standards, such missions are inexpensive. Mariner Jupiter/Saturn costs about the same as the American aircraft shot down in Vietnam in the week in which I am writing these words (Christmas 1972). The Viking mission itself costs about a fortnight of the Vietnam war.

I find these comparisons particularly poignant: life versus death, hope versus fear. Space exploration and the highly mechanized destruction of people use similar technology and manufacturers, and similar human qualities of organization and daring. Can we not make the transition from automated aerospace killing to automated aerospace exploration of the solar system in which we live?

Alas, we’re making the transition to “automated” space exploration, but we haven’t made — nor do we seem to intend to make anytime soon — the transition away from automated aerospace killing. (Sagan would no doubt have been appalled by this infographic portrait of human priorities as well.)

Mars and the Mind of Man is a cultural treasure — though long out of print, you might be able to score a used copy with some digging around, or look for it at your local library.

* Arthur C. Clarke had co-written the screenplay for Stanley Kubrick’s 1968 masterpiece, 2001: A Space Odyssey, which was inspired by Clarke’s 1948 short story “The Sentinel.”

Sally Ride, the First American Woman in Space, on What It’s Actually Like to Launch on the Space Shuttle

By:

Celebrating a pioneering astronaut, remarkable role model, and tireless advocate of science literacy.

On June 18, 1983, Sally Ride (May 26, 1951–July 23, 2012) boarded the space shuttle Challenger and became the first American woman in space. In 2012, Ride lost her life to pancreatic cancer. President Barack Obama rightfully called her “a national hero and a powerful role model,” who inspired generations of young women.

But besides being a pioneering astronaut, Ride was also a tireless advocate for more science and math in schools and a prolific co-author of children’s science books, including the 1986 tome To Space and Back (public library).

Mere days before the book went to the printer, the space shuttle Challenger exploded 73 seconds after launch on national television, leaving millions of Americans overcome with grief and anxiety about space. Ride was conflicted about whether or not to publish the book in its current form, but in the end decided to go ahead, making it a testament to the importance of space-exploration and a way to answer young people’s questions about being an astronaut. She proceeded to deliver this eloquent, riveting account of what it’s actually like to launch into space aboard the space shuttle — a wonderful way to celebrate her legacy of bravery:

The long elevator ride up the launch tower takes us to a level near the nose of the space shuttle, 195 feet above the ground. Trying hard not to look down at the pad far below, we walk out onto an access arm and into the ‘white room’ The white room, a small white chamber at the end of the movable walkway, fits right next to the space shuttle’s hatch. the only other people on the launch pad — in fact, the only other people for miles — are the six technicians waiting for us in the white room. They help us put on our escape harnesses and launch helmets and help us climb through the hatch. Then they strap us into our seats.

Because the space shuttle is standing on its tail, we are lying on our backs as we face the nose. It’s awkward to twist around to look out the windows. The commander has a good view of the launch tower, and the pilot has a good view of the Atlantic Ocean, but no one else can see much outside.

Launch minus one hour. We check to make sure that we are strapped in properly, that oxygen will flow into our helmets, that our radio communication with Mission Control is working, and that our pencils and our books — the procedure manuals and checklists we’ll need during liftoff — are attached to something to keep them from shaking loose. Then we wait.

The technicians close the hatch and then head for safety three miles away. We’re all alone on the launch pad.

Launch minus seven minutes. The walkway with the white room at the end slowly pulls away. Far below us the power units start whirring, sending a shudder through the shuttle. We close the visors on our helmets and begin to breathe from the oxygen supply. Then the space shuttle quivers again as its launch engines slowly move into position for blast-off.

Launch minus 10 seconds … 9 … 8 … 7 … The three launch engines light. The shuttle shakes and strains at the bolts holding it to the launch pad. The computers check the engines. It isn’t up to us anymore — the computers will decide whether we launch.

3 … 2 … 1 … The rockets light! The shuttle leaps off the launch pad in a cloud of steam and a trail of fire. Inside, the ride is rough and loud. Our heads are rattling around inside our helmets. We can barely hear the voices from Mission Control in our headsets above the thunder of the rockets and engines. For an instant I wonder if everything is working right. But there’s no more time to wonder, and no time to be scared.

In only a few seconds we zoom past the clouds. Two minutes later the rockets burn out, and with a brilliant whitish-orange flash, they fall away from the shuttle as it streaks on toward space. Suddenly the ride becomes very, very smooth and quiet. The shuttle is still attached to the big tank, and the launch engines are pushing us out of Earth’s atmosphere. The sky is black. All we can see of the trail of fire behind us is a faint, pulsating glow through the top window.

The atmosphere thins gradually as we travel farther from Earth. At fifty miles up, we’re above most of the air, and we’re officially ‘in space.’

The book also features this fascinating anatomy of the interior of the space shuttle by artist Mike Eagle:

To send Sally off, here’s the most exquisite cover of “Blue Moon” you’ll ever hear — thanks, Radiolab:

A Vintage Scientific Paper Published as a 38-Stanza Poem

By:

Verse and vengeance in vintage Australian astrophysics.

Remember last week’s first-ever poem published in a scientific journal? Turns out, it wasn’t the first. Reader Julia Deneva, a Cornell astronomer and fellow Bulgarian, alerts me to The Detection of Shocked Co/ Emission from G333.6-0.2 by New South Wales physicist J. W. V. Storey, a paper published as a 38-stanza poem, appeared in The Proceedings of the Astronomical Society of Australia in 1984. It was as much an act of creativity as it was one of vengeance. Deneva writes:

The unfortunate astronomer who got scheduled last at the annual meeting of said society decided to take revenge and gave his talk in verse — and later submitted it for publication.

The paper-poem is prefaced by the following hand-written note in the margin beside the first stanza:

It is, needless to say, just as geekily charming as it sounds:

I wrote my abstract, sent it in,
With words that don’t offend.
Imagine my horror to find that I
Am scheduled at the end.

Let me say, to be last speaker,
There are very few things worse.
And so this talk, to get revenge,
Will be entirely in verse.

The subject I address today
Is that of star formation.
And what we’ve found out recently
About the situation.

Stars start out as clouds of gas and
Dust and bits of spinning stuff.
Collapsing gravitationally
Until they’re dense enough.

They form themselves in little lumps,
(Or so says this bloke Jeans).
‘Dynamic Instabilities’
Whatever that term means.

A protostar is thus created,
Igniting nuclear fuel.
Before too long the star begins
To really lose its cool.

A massive wind begins to blow;
No one’s quite sure why.
But it’s quite clear the gas and stuff
Begins to really fly.

Well, from all this result what’s called
Protostellar outflow.
Bipolar, fast, and hot as hell —
We see it in CO.

But radio can’t tell us much;
There are but few transitions,
And cool CO’s so common, it
Confuses most positions.

So, most of what we know of this
Comes from the infrared —
That bit of spectrum in the middle
That decent people dread

Way back in 1976,
2 Micron lines were found
In Orion where, I’m sure you know,
Molecules abound.

Now everyone was most surprised,
These lines put out much power.
No one thought they’d be that strong —
Not even Neugebauer.

The lines were due to hydrogen
Molecules, and they
Don’t emit much until heated
To at least two thousand K

Well, people studied this for years,
Finding H2 everywhere.
But still these lines don’t tell you what
Density is there.

What we need’s another line:
Density dependent.
This view needs no genius
In order to defend it.

I’ve talked for several minutes now,
(I’ve half an hour to go),
I’m sure you’re most surprised I haven’t
Mentioned yet the KAO

Carbon monoxide, really hot,
Has heaps of good transitions
Depending critically upon
The density conditions.

These lines are in the far — IR,
But wait — here’s the best bit —
To see them you will need to use
The KAO, you guessed it!

In 1980, from the plane, we
Found it in Orion,
But no more CO could we find
Despite long hours of flyin’.

So models of Orion’s shock
Were looking really grand,
But it remained the only source
We claimed to understand.

We needed several other sources,
All of which we’d then compare.
But when we looked for shocked CO,
We always found it wasn’t there.

And so I searched for southern sources
Of this shocked H2,
And found it, in G333
Point six, minus, naught point two.

It’s really very, very bright
And made us all quite happy.
The data’s good, the lines are strong
(Though the slide don’t look real snappy.)

So, if we want to search again
For shocked CO, and wouldn’t you?
What better place than G333
Point six, minus, naught point two!

The problem with this new-found source,
I hardly need to warn you,
Is that it’s too far south to see
From sunny California.

And so to us the Kuiper came;
In May last year it made it.
The cost was astronomical,
But NASA mainly paid it.

Thus we made a set of flights
From Richmond Airforce Base.
One such flight is shown right here:
Our tracks’s this dotted trace.

How the instrument is made
Upon this slide is told;
It uses liquid helium
To keep all these bits cold.

Well, here’s the data — please don’t laugh,
It often looks this way.
A few times through the VAX and then
We’ll publish it as Ap J.

The line is there, I kid you not,
This dip here’s just the sky.
To see the peak you simply need
A good impartial eye.

Least-squares fitting gives a curve
From which derive the facts.
(Oh, let me thank the AAO
For lending me their VAX.)

Vlsr is fifty-three.
It’s pleasing, as you see.
The radio line velocities
More or less agree.

Intensity is really weak:
It’s two point nought by ten.
To the minus eighteenth power
(In watts per square cm.)

That’s thirty times as weak as we
Detected in Orion.
No wonder it took several years
Of concentrated tryin’

Well, as you see, I don’t yet have
Any numbers clear
For density, and things like that.
(It’s only been a year.)

But now we have not one, but two
CO sources, it is true:
Orion, and this G333
Point six, minus, naught point two.

In fact, the sources now are three
Because, again last May,
The very next flight that we did
Found CO in Sgr A.

Well, thank you all for listening
(Though some of you have slept)
I wonder now, will Dick McGee
This manuscript accept?

Now that’s a whole new layer the creativity-in-science conversation.
