Tom's SciCast Tom Kennedy

A look back on my life in science, birds, fish, invasive species, streams, dams, and climate change and sleeping lizards.  

Where is every one? Why haven't we been visited by alien races, made contact with aliens, or even discovered a hint of an alien race? Ever since Fermi asked this simple question, people have been coming up with answers as to why we don't see aliens. Some solutions are scary, but I think a potential answer could be found by looking at our own solar system. 

I believe humans are special and improve our chances of surviving as a species, I explain why we should colonize the solar system and beyond. 

I explore how the Silurian Hypothesis provides insight into what it takes for a planet to host or evolve a civilization, how we might detect them, and the legacy of humans on Earth.  

After 6 months, I'm back! I talk about how some of my views have changed to become more nuanced and how my own biases shape the way I think about astrobiology. 

In researching astrobiology for my up coming book, I've started to view the evolution of life and civilizations in a paradigm shifting way that challenges the very basics of our understanding of evolution. Listen in as I explain why I think evolution is progressive.
