Earth in True Perspective

The small green square in the photo to the left, a brief, single snapshot in time—what appears to be only a cold, empty void of absolute darkness, with nary a single star to be seen by the naked eye—in fact contains within the dark confines of its hazy boundaries the luminous wonders of over 10,000 beaming galaxies, each shining with the light of a trillion suns.

Back here at home, only a few short footsteps from your door, countless species of sea life and coral live out their lives: lush cliffs and caves, flora and fauna, and schools of fish, from tiny as needles, to larger than a great dane―millions of intertwined species, an interplay of flourishing ecosystems, locked together in singular symbiosis. An octopus drifts silently by, observing its surroundings in the stillness of soft, quiet reflection, as the full spectrum of the rainbow―liquid lines of chameleon color, glimmer just beneath its membranous skin.

With no moon, and no light above save for distant twinkles of starlight and the light of worlds light years away, two distant lightning storms on the East and West horizons bring intense contrast to the endless voids both above and below. As far as the eyes can see, no land interrupts this unbroken line of darkness. Complete blackness blankets the waters beneath, with the exception of phosphorescent plankton, which flash and glimmer like sparks in the night as we glide silently through the waters, or when softly stirred by a cool caress from the back of your hand. The dividing line between jet black sea and infinite sky is wholly absent, evoking a sense of leisurely drift through those deep, distant space nebulae—a synaesthetic, psychedelic experience, much akin to sensory deprivation.

The luminous arms of the Milky Way, usually no more than a faint trace across the sky when enveloped in the chaos and cacophony of our contemporary pachinko parlor-laced urban climes, still a dim spark, even, from deep in the meadows of a distant countryside—shine bright as Times Square overhead. An experience beyond words, evocative of the distinctive hallmarks called to mind through the end sequences of Contact, or Kubrick's 2001.

Across the universe, the distant void yields to powerful beams of light borne from nuclear fusion sourced deep in the hearts of a trillion stars, each shining radiant warmth and light down upon alien worlds. Consider, for the briefest of moments: the unimaginably vast number of living worlds that circle those other suns, in this tiny distant window of space and time alone. Each and every one holds, 'tween the span of its horizons, boundless wonders and volumes of mysteries—countless miracles of dazzling complexity that mirror our own richly-populated, endlessly intricate, fractal, yet familiar home world.

Imagine how many others just like you are out there right now, this very moment―looking up to us in curiosity and contemplation, through the dizzying, stellar symphony of unfamiliar constellations dancing their way across strange, alien nighttime skies. Each calls back to us through the unfathomable void, making their way across the vast expanse of more than thirteen billion light years of space and time.

Los Alamos Event Horizon

In Kona, Hawai‘i, in July 2013, I met Richard J. Hughes, then a Laboratory Fellow in the Physics Division at Los Alamos National Laboratory. Hughes had founded and co-led the Laboratory’s Quantum Communications team and served as Scientific Director of its Quantum Institute.

Few institutions represent science at the frontier of consequence as powerfully as Los Alamos. Established in 1943 as Project Y of the Manhattan Project, the Laboratory was built to turn problems at the edge of the possible into national capability.

Hughes had also chaired the Technology Experts Panel that produced A Quantum Information Science and Technology Roadmap, serving as its document coordinator. That roadmap had strongly influenced the direction of my graduate work.

When I introduced myself at the conference, I told him how much his leadership had meant to me.

“To the contrary,” he replied. “It’s an honor for me to meet you—you inspired me.”

I was taken aback. “How could that be? I was only a graduate student at the time.”

Hughes referred to the collection of technology-assessment reports I had prepared through my work with the Advanced Research and Development Activity’s QuIST program. Working from Roppongi Hills in Tokyo, I traveled to leading national laboratories, universities, and corporate research institutes across East Asia and Europe to assess the emerging quantum-information landscape. The resulting reports were circulated among scientists and program leaders across the United States.

Hughes told me that those assessments had helped demonstrate the value of a structured national appraisal of the field. They informed, he said, his approach to organizing the expert-led roadmap effort.

That exchange changed my understanding of scientific influence. Work can travel much farther through institutions than its author is ever permitted to see.

Our conversation led Hughes to invite me to visit Los Alamos.

“How long should I schedule?” I asked. “Two days, two weeks, two months?”

He winked. “You know, Los Alamos is a black hole. With all the exciting projects we have going on here, you might disappear altogether—and never leave.”

The next frontier of quantum communications


Listening to Rupert Ursin's closing talk on Free-Space Quantum Communication towards Satellites

Over the last week, we shared the sunset from the summit of Mauna Kea, tracked binary star clusters and shining nebulae from telescopes atop the mountain, joined a round of native Hawaiian chants to give thanks to the land, the jungle and our ancestors in a hand-built, solar-powered treehouse deep in the rainforest — snorkeled through the same crystalline waters as the sea turtles and dolphins in Waikoloa Bay, enjoyed fresh coconut water and enchanted conversations on quantum mechanics and the nature of reality as whirling dervishes, beautiful dancers flitted around us at the naked drum circle of Kehena's black sand beach  took in arms-length views of active cliffside lava flows and giant, billowing sulfuric gas clouds, violently heaving and shaking the ground beneath our feet, erupting into massive steam columns as they crashed into the ocean, slicing through the thin ribbon of coastline interface between land and sea, dead in the middle of the night, miles from civilization ...
