    Fermi Paradox

    Fermi Paradox

    Ever wondered where all the aliens are? It’s actually very weird that, as big and old as the universe is, we seem to be the only intelligent life. In this episode, Josh examines the Fermi paradox, and what it says about humanity’s place in the universe.

    Great Filter

    The Great Filter hypothesis says we’re alone in the universe because the process of evolution contains some filter that prevents life from spreading into the universe. Have we passed it or is it in our future? Humanity’s survival may depend on the answer.

    X Risks

    Humanity could have a future billions of years long – or we might not make it past the next century. If we have a trip through the Great Filter ahead of us, then we appear to be entering it now. It looks like existential risks will be our filter.

    Natural Risks

    Natural Risks

    Humans have faced existential risks since our species was born. Because we are Earthbound, what happens to Earth happens to us. Josh points out that there’s a lot that can happen to Earth - like gamma ray bursts, supernovae, and runaway greenhouse effect.

    Biotechnology

    Biotechnology

    Natural viruses and bacteria can be deadly enough; the 1918 Spanish Flu killed 50 million people in four months. But risky new research, carried out in an unknown number of labs around the world, are creating even more dangerous humanmade pathogens.

A great podcast Josh

I still think however it could be all over in 200 years. You can’t put out the fire of ( man made )
climate change by smothering it by an unbridled overpopulation problem. The human race can be very self centered a lot of the time and right now we are more and more intolerant of each other. If we can bring the population footprint down and find a real base power alternative to fossil fuel then we just might make it. 👍

Incredibly well researched and engaging

This series is amazing. It is such an incredibly well researched podcast, broken down and told in a way that is so engaging and easy to understand. Once I finished I went back and listened to the whole thing again. Josh has done a fantastic job and everyone should give it a listen.
