Exploring the Origins and Laws of Life with Astrobiologist Professor Sara Walker
As humans search for life beyond Earth, one of the biggest questions is: what exactly is life, and how did it come to be? Professor Sara Walker, an astrobiologist and theoretical physicist, has made it her life’s work to explore these fundamental questions. In this article, we will take a closer look at Professor Walker’s work and what it can teach us about the origins and laws of life.
Background and Career
Sara Walker earned her Ph.D. in physics from the University of Queensland in Australia. She then worked at the National Institutes of Health, the Santa Fe Institute, and the Massachusetts Institute of Technology (MIT). At MIT, she is an assistant professor of physics and a member of the Santa Fe Institute External Faculty.
Her work has focused on exploring the origins of life, alien life, and whether or not there are universal “laws of life” that can guide our search for it. She has authored numerous research papers and given talks worldwide, earning international recognition as a leading expert in her field.
Universal “Laws of Life”
One of the most fascinating aspects of Professor Walker’s work is her exploration of whether or not there are universal “laws of life.” In other words, are specific principles or rules dictating how life emerges and evolves, regardless of the particular chemical and environmental conditions?
This is a difficult question, but Professor Walker has made some progress. One of her key findings is that life may be more “disordered” than we previously thought. In other words, it may be more about the flow of energy and information than the precise arrangement of molecules. This could have important implications for our search for life beyond Earth, as we may need to look for more complex energy flows rather than specific chemical signatures.
Searching for Alien Life
Another area of interest for Professor Walker is the search for alien life. She acknowledges that this is a difficult task that is worth pursuing nonetheless. Her approach is to focus on what we know about life on Earth and use that as a guide for what to look for elsewhere.
For example, one of the defining characteristics of life on Earth is its ability to replicate itself. Therefore, Professor Walker suggests looking for “self-copying systems” on other planets or moons. This could include RNA molecules or digital code if future humans can leave it behind on other worlds.
The Importance of Interdisciplinary Research
Finally, Professor Walker emphasizes the importance of interdisciplinary research when studying life’s origins and laws. This means bringing together scientists from different fields, such as physics, chemistry, biology, and computer science, to approach these questions from multiple angles.
She also acknowledges the importance of art and culture in understanding our place in the universe. As she puts it, “Science is only one way of understanding who we are and where we come from. We need to bring in other perspectives, other ways of describing our experience, to fully appreciate our universe’s complexity and beauty.”
In Conclusion
Professor Sara Walker’s work is inspiring in its scope and ambition. By exploring the origins and laws of life, she is helping us better understand our place in the universe and what it means to be alive. Her interdisciplinary approach and emphasis on the importance of culture and art make her work all the more fascinating and relevant for people from all walks of life.
