Sara Walker: prediction

Transcript context

…Black holes in every way, so untouchable to us or unlikely be detectable by us with whatever sensory mechanisms we have. Yeah. But the other way I think about it is there is probably hopefully life out there. I do work on life detection efforts in the solar system and I’m trying to help with the Habitable Worlds Observatory mission planning right now and working with the biosignatures team for that to think about exoplanet biosignatures. I have some optimism that we might find things, but there are the challenges that we don’t know the likelihood for life, which is what you were talking about. If I get to a more grounded discussion, what I’m really interested in doing is trying to solve the origin of life so we can understand how likely life is out there. I think that the problem of discovering alien life and solving the origin of life are deeply coupled and in fact are one in the same problem, and that the first contact with alien life will actually be in an origin of life experiment. But that part I’m super interested in. And then there’s this other feature that I think about a lot, which is our own technological phase of development as what is this phase in the evolution of life on a planet? If you think about a biosphere emerging on a planet and evolving over billions of years and evolving into a technosphere. When a technosphere can move off planet and basically reproduce itself on another planet, now you have biospheres reproducing themselves. Basically they have to go through technology to do that. And so, there are ways of thinking about the nature of intelligent life and how it spreads in that capacity that I’m also really excited about and thinking about. And all of those things for me are connected. We have to solve the origin of life in order for us to get off planet because we basically have to start life on another planet. And we also have to solve the origin life in order to recognize other alien intelligence. All of these things are literally the same problem. Right. Understanding the origin of life here on earth is a way to understand ourselves. And to understanding ourselves as a prerequisite from being able to detect other intelligent civilizations. I, for one, take it for what it’s worth on Ayahuasca, one of the things I did is zoom out aggressively, like a spaceship. And it would always go quickly through the galaxy and from the galaxy to this representation of the universe. And at least for me from that perspective, it seemed like it was full of alien life. Not just alien life, but intelligent life.…
