Cool Worlds

An Event So Deadly it Makes Parts of the Galaxy Inhospitable

Cool Worlds

Summary

Ohio veterans express strong discontent regarding Senator Sherrod Brown's policies, particularly criticizing his support for taxpayer-funded benefits for illegal immigrants while allegedly neglecting veterans' healthcare needs. They argue that Brown has broken promises to those who served in the military by attempting to eliminate VA healthcare benefits, claiming that their sacrifices are being overlooked in favor of providing benefits to non-citizens.

In a shift to a scientific discussion, the transcript delves into the concept of galactic habitability, exploring the potential dangers posed by astronomical events such as supernovae and gamma-ray bursts. While supernovae are considered a threat to life, their impact is limited to nearby occurrences. In contrast, gamma-ray bursts, which can occur at much greater distances, present a more significant risk to life on Earth by potentially stripping away the ozone layer and causing mass extinction events.

The conversation highlights the ongoing debate among scientists regarding the existence of a "galactic habitable zone," suggesting that while certain regions of the galaxy may be more conducive to life, the overall threat landscape is complex and not fully understood. The discussion emphasizes the need for further research to clarify these cosmic risks and their implications for life in the galaxy.

Show Notes

Space is a bleak, hostile environment. Asteroid strikes, supernovae and gamma ray bursts could wipe us out at any moment. But could certain parts of the galaxy be more dangerous than others? And could this explain why we live, when and where we live?Written and presented by Prof David Kipping, guest starring Jackson Kipping and edited by Jorge Casas.→ Support our research program: https://www.coolworldslab.com/support→ Get Stash here! https://teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

Is there a way to naturally classify the different types of planets in the Universe? Two of the most fundamental properties of any object are its mass and size and generally one expects size to increase as we add more mass. The relationship between size and mass itself changes though at certain points, and this offers a clear way to classify worlds. Graduate student Jingjing Chen of the Cool Worlds Lab discusses one component of her new paper which does just this, classifying planets based off their mass and size and concluding that just four broad categories of planets explain the data.::More about this Video::► Chen & Kipping (2016), "Probabilistic Forecasting of the Masses and Radii of Other Worlds": http://arxiv.org/abs/1603.08614► "Forecaster" open-source software package: https://github.com/chenjj2/forecaster► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk::Playlists For Channel::Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorldsCool Worlds Research ► http://bit.ly/CoolWorldsResearchGuest Videos ► http://bit.ly/CoolWorldsGuestsQ&A Videos ► http://bit.ly/CoolWorldsQAScience of TV/Film ► http://bit.ly/ScienceMovies::Follow us::SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribeCool Worlds Lab http://coolworlds.astro.columbia.eduTwitter https://twitter.com/david_kippingInstagram https://www.instagram.com/cool.worldsTHANKS FOR WATCHING!!

The Galaxy is approximately 13 billion years old, which makes one wonder - just how many civilizations could have come and gone across that ocean of time? Today, we try something a little bit different for this channel, and imagine when and how the first civilization could have lived. The story is a fiction, but it provides a narrative around which we can more viscerally experience the conditions of the early cosmos, and the fragility of life itself.Written & presented by Prof David Kipping→ Support our research program: https://www.coolworldslab.com/support→ Get Stash here! https://teespring.com/stores/cool-worlds-storeI'll be speaking at RAND in Santa Monica, March 7th, on the future of space exploration, registration link here: https://www.rand.org/events/2022/03/7-8.htmlTHANK-YOU to our supporters D.
