Primordial black holes are tiny versions of the big beasts you typically think of. They’re so small, they could easily fit inside stuff, like a planet, or a star… or a person. So, needless to say, this has piqued the curiosity of our Dead Planeteers.

Leah and Chelsea want to know, can you put primordial black holes inside things and what happens if you do?

Black hole astronomer Allison Kirkpatrick at the University of Kansas is back to help them figure this one out. And it turns out, despite being very small, these black holes are incredibly heavy, so ingesting and/or hugging them seems firmly off the cards — much to Chelsea’s displeasure.

Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from punching a hole in a planet to unifying the asteroid belt – and subjects them to the laws of physics to see how they fare.

Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity.

The observations spotlight the volatile processes that shape star systems like our own, offering a unique glimpse into the primordial stages of planetary formation.

“Beta Pictoris is at an age when planet formation in the terrestrial planet zone is still ongoing through giant asteroid collisions, so what we could be seeing here is basically how rocky planets and other bodies are forming in real time,” said Christine Chen, a Johns Hopkins University astronomer who led the research.

To define areas that must be protected to prevent the most likely and imminent extinctions, we propose Conservation Imperatives—16,825 unprotected sites spanning ~164 Mha of the terrestrial realm that harbor rare and threatened species. We estimate that protecting the Conservation Imperatives would cost approximately US$169 billion (90% probability: US$146—US$228 billion). Globally, 38% of the 16,825 sites are either adjacent to or within 2.5 km of an existing protected area, potentially reducing land acquisition and management costs. These sites should be prioritized for conservation action over the next 5 years as part of a broader strategy to expand the global protected area network.

RPTU University of Kaiserslautern-Landau has shown for the first time, in a joint study with BOKU University, that permaculture brings about a significant improvement in biodiversity, soil quality and carbon storage.

In view of the challenges of climate change and species extinction, this type of proved to be a real alternative to conventional cultivation—and reconcile and .

Permaculture uses natural cycles and ecosystems as blueprint. Food is produced in an agricultural ecosystem that is as self-regulating, natural and diverse as possible. For example, is integrated into the cultivation of crops or the diversity of beneficial organisms is promoted in order to avoid the use of mineral fertilizers or pesticides.

In this episode of the 5th Industrial Revolution VODcast we sit down with Dr. Jordan Okie of Arizona State University School of Earth and Space Exploration to discuss a key relevancy to the next industrial revolution, sustainability, through the lens of Dr. Okie’s area of expertise: Ecology and Biology. Our key takeaways: We are in a race against time and extinction. We will need to find a way to evolve through technology to survive, be it here on Earth or in our exploration of Space.

Two asteroids, including the newly detected 2024 MK, will pass Earth safely this week, coinciding with Asteroid Day. The event highlights efforts such as ESA’s asteroid deflection mission and their new Flyeye telescope system aimed at improving our detection and response to these celestial threats.

Two large asteroids will safely pass Earth this week, a rare occurrence perfectly timed to commemorate this year’s Asteroid Day. Neither poses any risk to our planet, but one of them was only discovered a week ago, highlighting the need to continue improving our ability to detect potentially hazardous objects in our cosmic neighborhood.

The event is so rare because of its large size – 375 meters (1230 feet) average diameter – as well as its proximity to the Earth.

“The 2029 flyby is an incredibly rare event,” ESA explained in an X post. “By comparing impact craters across the Solar System with the sizes and orbits of all known asteroids, scientists believe that an asteroid as large as Apophis only comes this close to Earth once every 5,000 to 10,000 years.

From the article:

Longtermism asks fundamental questions and promotes the kind of consequentialism that should guide public policy.

Based on a talk delivered at the conference on Existential Threats and Other Disasters: How Should We Address Them? May 30–31, 2024 – Budva, Montenegro – sponsored by the Center for the Study of Bioethics, The Hastings Center, and The Oxford Uehiro Center for Practical Ethics.

For twenty years, I have been talking about old age dependency ratios as an argument for universal basic income and investing in anti-aging therapies to keep elders healthy longer. A declining number of young workers supporting a growing number of retirees is straining many welfare systems. Healthy seniors are less expensive and work longer. UBI is more intergenerationally equitable, especially if we face technological unemployment.

New observations spotlight the volatile processes that shape star systems like our own, offering a unique glimpse into the primordial stages of planetary formation.

Astronomers have captured a snapshot of a giant asteroid collision in Beta Pictoris, revealing insights into early planetary formation. The study, using data from the James Webb and Spitzer Space Telescopes, tracked dust changes around the star. The findings suggest a massive collision 20 years ago, altering our understanding of this young star system’s development.

There’s a lot of other ways that AI could really take things in a bad direction.

One of the OpenAI directors who worked to oust CEO Sam Altman is issuing some stark warnings about the future of unchecked artificial intelligence.

In an interview during Axios’ AI+ summit, former OpenAI board member Helen Toner suggested that the risks AI poses to humanity aren’t just worst-case scenarios from science fiction.

“I just think sometimes people hear the phrase ‘existential risk’ and they just think Skynet, and robots shooting humans,” Toner said, referencing the evil AI technology from the “Terminator” films that’s often used as a metaphor for worst-case-scenario AI predictions.
