Eric Idle joins the discussion on the future of the universe and potential asteroid threats. The conversation takes a humorous turn with calculations on urine cooling energy in urinals and the concept of other species taking over from humans, like dolphins. The episode also touches on upcoming episodes, Roman history stories, and sponsor ads for Bolin Branch and SAP Concur Solutions.
The universe's rapid expansion will eventually make distant galaxies vanish from view, creating a lonely future for humanity.
Asteroid impacts pose a significant threat, highlighting the importance of predicting and preventing potential catastrophic outcomes.
Deep dives
The Future of the Universe and Distant Galaxies
In over 100 billion years, space will have expanded so much that we won't be able to see distant galaxies anymore. The universe's acceleration means galaxies will move away faster than the speed of light. This expansion will create a lonely time for humanity, with distant galaxies vanishing into eternal darkness.
Threat of Asteroids and Potential Extinction
Asteroids pose a significant threat, potentially causing mass extinctions and varied catastrophic outcomes. Impact scenarios include direct hits causing destruction, creating tsunamis, or disrupting the food chain. Efforts to predict and prevent asteroid impacts are crucial to mitigating such risks.
Climate Change and Human Impact
Human activities, such as energy-intensive practices like making ice cubes for urinals, contribute to climate change. A focus on sustainability is essential to slow down the climate crisis. Awareness of wasteful practices can lead to more responsible environmental stewardship.
We know the universe is rapidly expanding but what happens if other galaxies disappear from view? That’s what Eric Idle wants to know as he ponders the future and what it holds in store. Solar scientist Lucie Green says this is not worth dwelling on because we’ll all be wiped out by an asteroid at some point anyway, which leads to a discussion about whether anywhere is still safe. Away from physics, Brian Cox and Robin Ince learn that one of the major contributors to global warming is the urinal cooling industry, which raises important questions about human stupidity. Should we let another species have a go? Chris Addison reckons dolphins might do a better job than we have but admits there are some major logistical issues.
