Alien Crash Site

This week, Alien Crash Site invites Lindy Elkins-Tanton into the Zone. Lindy is a Foundation and Regents Professor at Arizona State University’s School of Earth and Space Exploration. She is the Vice-president of ASU’s InterPlanetary Initiative. And, she is the principal investigator of NASA’s Psyche Mission: an attempt to understand a metal rich asteroid located between Mars and Jupiter which may provide us with some clues about planetary formation.

After a career in Silicon Valley, Gary Bengier pursued passion projects, studying astrophysics and philosophy. He’s spent the last two decades thinking about how to live a balanced, meaningful life in a rapidly evolving technological world. This self-reflective journey infuses his novel, Unfettered Journey, with insights about our future and the challenges we will face in finding purpose.

Before turning to writing speculative fiction, Gary worked in a variety of Silicon Valley tech companies. He was eBay’s Chief Financial Officer, and led the company’s initial and secondary public offerings. Gary has an MBA from Harvard Business School, and an MA in philosophy from San Francisco State University.

In this special crossover interview, Complexity Podcast host Michael Garfield and Alien Crash Site hostess Caitlin McShea plumb the thematic depths at the foundation of this Gary's fictional exploration of humanity's here after.

SFI's InterPlanetary Project teamed up with New School Policy and Design for Outer Space to present this conversation on Complex Time, as part of the 2021 Venice Architecture Biennale.

When imagining InterPlanetary life and human civilization in space, it's always a matter of time. Philosophers and physicists from Aristotle to Carlo Rovelli have deeply considered the nature of time. Given the scale of the social-technical systems required for any off-Earth endeavor, however, this age-old discussion requires broader input.

Complex systems emerge from a multitude of time-scales, clocks, arrows of time, and therefore a multitude of rates at which things come together and fall apart. But our experience of time seems to vary with the perspective we take on a subject: the lifespan of an organism seems to be the result of constraints of mass and energy; a firm, the flows and stocks of capital and labor; a state, the developments of its people and their political economy.

How do these different time-scales interrelate and inform one another on Earth today? What might a reconsideration of the complexity of time add to our collective effort to sustain life on and with other planets? And how can we create scalable yet adaptable social-technical systems that work together to achieve our interplanetary futures?

This panel will bring together researchers, scientists and theorists to attempt an answer to these questions. They will explore the possible methods and tools for complex collaboration, and consider what it will take to support and grow life beyond Earth while keeping, at the center of it all, the beating heart of time.

Participants Include Sean Carroll, Jeli's Laura Maguire, NASA's Zara Mirmalek, and Geoffrey West. The discussion will be moderated David Krakauer.

Astrobiology is a paradoxically established and yet still burgeoning field that is reconsidering the fundamental boundaries of what we mean by "life," while simultaneously searching for that life beyond Earth. Past guests have outlined how difficult the search for life is; they've contributed new detection methods and measures, they've proposed new tools, and they're working to establish new standards of evidence in support of such a discovery.

This week we ask SFI post-doctoral fellow, Natalie Grefenstette, how we can best equip ourselves to recognize life in space, given how little we know about life, at all. Natalie is working on the Agnostic Biosignature Project, a multi-institutional endeavor funded by NASA.

Alien Crash Site is taking a small break, to return the week of October 24th. Why? Because SFI, in partnership with New School Policy and Design for Outer Space, are hosting an InterPlanetary panel discussion on Complex Time. October 21st, 10 am MDT. Free to attend.

Chris Kempes is a professor at the Santa Fe Institute. He is a mathematical biologist, who works on scaling laws, and is ultimately interested in where those scaling laws break down. What are their limits? What is the physiological constraint for life on earth? How small can life be? How big? How might that constraint change in other environments?

He recently published a paper, along with David Krakauer, titled “The Multiple paths to Multiple Life” that attempts to reconfigure how we think about life forms, and life origins events. We discuss this provocative proposal at length, along with the scaling research I just described, before we shift to our venture into the Zone to pursue a totally disgusting but revelatory artifact, if we can even call it that.

For more context on themes described in this episode, you might revisit past interviews with Nina Lanza who is seeking signs of life on Mars, Michael Lachmann who talks origins of life in general, Cole Mathis and his work on Assembly Theory, and our last interview with Heather Graham who worked on assembly theory as well as a stoichiometric approach to life detection in a paper she co-authored with Chris.

What do we look for, when we don’t know what we’re looking for? As we announce more missions seeking life in the universe, and as we build new technologies to assist in that pursuit, how do we ensure we don’t miss it when we come across it? How can we best prepare ourselves to recognize life unlike our own?

This week, Heather Graham fills us in on exactly how she is seeking out these “agnostic” Biosignatures. Heather is a researcher at NASA’s Goddard Space Flight Center. She’s an organic geochemist and she’s also an astrobiologist. Earlier this summer she published two papers proposing two very cool and very different methods for life detection. We discuss both in this conversation, as well as how easily fooled we might be in our pursuit of past life by the clues we have today. We talk about the rigorous ways space missions are managing contamination, the intersection of art and science, the difference between information and meaning, and we end with a discussion of heather’s ideal alien object, which could definitely change our understanding of the universe, so long as we handle it properly.

As we stand on the precipice of becoming an InterPlanetary Species, we need to think carefully about what an InterPlanetary governance structure looks like, and how it ensures that space is explored and protected for the benefit of all humanity. Dr. Timiebi Aganaba is the perfect person to walk us through all that's at stake in such a huge consideration.

Timiebi Aganaba is an Assistant Professor at Arizona State’s school for the Future of Innovation in Society, with a courtesy appointment at the Sandra Day O’ Connor school of Law. She has worked at the Nigerian National Space Research and Development Agency. She has also worked as a space industry consultant for the Canadian Space agency. She holds a Masters of Science from the International Space University, and a Masters of Law and a PhD from the Institute of Air and Space Law at McGill University, and she was recently appointed to the Science Advisory Board at the SETI Institute. A true "space-governance" repository, coming at this not-so-distant future very thoughtfully and inclusively.

In this episode, we discuss everything from current international law and it’s applications to future space law, space law that already exists, the trade-offs between optimization and speed of implementation, how to ensure diversity and representation of perspectives when creating new international and/or interplanetary law, the intersection of federal space agencies and the private sector, and how much money actually matters in the space game. Then we talk through a powerful piece of extraterrestrial technology that might allow us to address and correct a looming planetary problem.

This week Alien Crash Site brings aerospace engineer Ryan McGranaghan into the Zone. Ryan currently works at NASA’s Jet Propulsion Lab as a Jack Eddy Post-doctoral research fellow. His work focuses on the application of data assimilation, complex systems analyses and data science to space science research…specifically work within the realm of the “space environment.”

We spend this conversation talking about what lies in the “space between.” The space between planetary bodies, the space between research disciplines, the space between intention and expression, the space between interlocutors attempting to communicate, the “space between” that’s all around us.

40:28 Alien Crash Site Question

This week, Computational Cognitive Scientist Vanessa Ferdinand provides us with her skeptical take on the very premise of Roadside Picnic. Given her research on cultural evolution, and how cultural artifacts are changed by the cognitive systems that perceive them, she had quite a few problems with the idea of finding and using an object created by an alien lifeform.

She explains her reasoning, but she eventually suspends her disbelief, settles comfortably into the fiction, and describes an alien artifact that she believes will alter our understanding of ourselves, each other, these aliens, and the universe itself.
