Langdon kept scanning down the phone screen until he found a seemingly innocuous CNN Live link titled “What Did Kirsch Discover?”

He launched the link and held the phone so Ambra could see it as well. As the video began to play he turned up the volume, and he and Ambra leaned together so they could hear the video over the roar of the helicopter’s rotors.

A CNN anchor appeared. Langdon had seen her broadcasts many times over the years. “We are joined now by NASA astrobiologist Dr. Griffin Bennett,” she said, “who has some ideas regarding Edmond Kirsch’s mysterious breaking discovery. Welcome, Dr. Bennett.”

The guest—a bearded man in wire-rimmed glasses—gave a somber nod. “Thank you. First off, let me say that I knew Edmond personally. I have enormous respect for his intelligence, his creativity, and his commitment to progress and innovation. His assassination has been a terrible blow to the scientific community, and I hope this cowardly murder will serve to fortify the intellectual community to stand united against the dangers of zealotry, superstitious thinking, and those who resort to violence, not facts, to further their beliefs. I sincerely hope the rumors are true that there are people working hard tonight to find a way to bring Edmond’s discovery to the public.”

Langdon shot Ambra a glance. “I think he means us.”

She nodded.

“There are many people who are hoping for that as well, Dr. Bennett,” the anchor said. “And can you shed any light on what you think the content of Edmond Kirsch’s discovery might be?”

“As a space scientist,” Dr. Bennett continued, “I feel I should preface my words tonight with a blanket statement … one that I believe Edmond Kirsch would appreciate.” The man turned and looked directly into the camera. “When it comes to the notion of extraterrestrial life,” he began, “there exists a blinding array of bad science, conspiracy theory, and outright fantasy. For the record, let me say this: Crop circles are a hoax. Alien autopsy videos are trick photography. No cow has ever been mutilated by an alien. The Roswell saucer was a government weather balloon called Project Mogul. The Great Pyramids were built by Egyptians without alien technology. And most importantly, every extraterrestrial abduction story ever reported is a flat-out lie.”

“How can you be sure, Doctor?” the anchor asked.

“Simple logic,” the scientist said, looking annoyed as he turned back to the anchor. “Any life-form advanced enough to travel light-years through interstellar space would have nothing to learn by probing the rectums of farmers in Kansas. Nor would these life-forms need to morph into reptiles and infiltrate governments in order to take over earth. Any life-form with the technology to travel to earth would require no subterfuge or subtlety to dominate us instantaneously.”

“Well, that’s alarming!” the anchor commented with an awkward laugh. “And how does this relate to your thoughts on Mr. Kirsch’s discovery?”

The man sighed heavily. “It is my strong opinion that Edmond Kirsch was going to announce that he had found definitive proof that life on earth originated in space.”

Langdon was immediately skeptical, knowing how Kirsch felt about the topic of extraterrestrial life on earth.

“Fascinating, what makes you say that?” the anchor pressed.

“Life from space is the only rational answer. We already have incontrovertible proof that matter can be exchanged between planets. We have fragments of Mars and Venus along with hundreds of samples from unidentified sources, which would support the idea that life arrived via space rocks in the form of microbes, and eventually evolved into life on earth.”

The host nodded intently. “But hasn’t this theory—microbes arriving from space—been around for decades, with no proof? How do you think a tech genius like Edmond Kirsch could prove a theory like this, which seems more in the realm of astrobiology than computer science.”

“Well, there’s solid logic to it,” Dr. Bennett replied. “Top astronomers have warned for decades that humankind’s only hope for long-term survival will be to leave this planet. The earth is already halfway through its life cycle, and eventually the sun will expand into a red giant and consume us. That is, if we survive the more imminent threats of a giant asteroid collision or a massive gamma-ray burst. For these reasons, we are already designing outposts on Mars so we can eventually move into deep space in search of a new host planet. Needless to say, this is a massive undertaking, and if we could find a simpler way to ensure our survival, we would implement it immediately.”

Dr. Bennett paused. “And perhaps there is a simpler way. What if we could somehow package the human genome in tiny capsules and send millions of them into space in hopes one might take root, seeding human life on a distant planet? This technology does not yet exist, but we are discussing it as a viable option for human survival. And if we are considering ‘seeding life,’ then it follows that a more advanced life-form might have considered it as well.”

Langdon now suspected where Dr. Bennett was going with his theory.

“With this in mind,” he continued, “I believe Edmond Kirsch may have discovered some kind of alien signature—be it physical, chemical, digital, I don’t know—proving that life on earth was seeded from space. I should mention that Edmond and I had quite a debate about this several years ago. He never liked the space-microbe theory because he believed, as many do, that genetic material could never survive the deadly radiation and temperatures that would be encountered in the long journey to earth. Personally, I believe that it would be perfectly feasible to seal these ‘seeds of life’ in radiation-proof, protective pods and shoot them into space with the intent of populating the cosmos in a kind of technology-assisted panspermia.”
