Crowded or Lonely? The Statistics of Alien Life Cool Worlds 2024-06-19 | New research paper from the Cool Worlds Lab! Today we explore the implications of a classic result in statistics but applied to alien life for the first time. The result implies a startling conclusion, the cosmos is either teeming with intelligent civilizations, or we're essentially alone. Join us today as explore how this works and what the implications might be.Written & presented by Prof. David Kipping.→ Support our research: coolworldslab.com/support→ Get merch: teespring.com/stores/cool-worlds-store→ Check out our podcast: www.youtube.com/@CoolWorldsPodcastTHANK-YOU to D.

Are Dyson Spheres Actually Possible? Cool Worlds 2024-08-02 | Use code coolworlds at incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan.The idea of Dyson Spheres was a radical proposal by the physicist Freeman Dyson, an enormous shell of material enveloping a star. Dyson's idea may be over half a century old, but interest in looking for such objects has only grown in the decades since. But how would such structures work? Are they physically even possible? And what might someone use them for? Today, we dive into the physics of Dyson spheres.Written & presented by Prof. David Kipping. Edited by Jorge Casas.

How Thermodynamics Holds Back Negative Carbon Tech Cool Worlds 2023-09-19 | Go to our sponsor betterhelp.com/coolworlds for 10% off your first month of therapy with BetterHelp and get matched with a therapist who will listen and help.Direct Air Capture (DAC) has been getting more and more attention over the last few years. Could we avert climate change by pulling carbon dioxide out of the atmosphere? Could we not just stop, but actually *reverse* the damage done? Unfortunately, most don't fully appreciate just quite how much CO2 we've emitted and the outrageous scale of the problem facing us. Today, we apply the fundamental principles of thermodynamics to question whether this is even feasible.Written & presented by Prof. David Kipping. Edited by Jorge Casas.

Whats Stopping Us From Building a Warp Drive? Cool Worlds 2023-08-01 | Get a 7-day free trial and 25% off Blinkist Annual Premium by clicking here: blinkist.com/coolworldslabA faster-than-light (FTL) warp drive would arguably represent the most important invention of all time. In 1994, Miguel Alcubierre gave all of us hope as he found a solution within general relativity that would cause the necessary warping of space. But after nearly 30 years of further study, what does our current understanding of physics say about the feasibility of a warp drive?Written & presented by Prof. David Kipping. Thanks to Bobrick Martire for clarifications and to John Michael Godier and team for audio from their interview with Alcubierre (youtu.be/JafY92PhgKU).

Are UFOs Legitimate Science? Cool Worlds 2023-07-10 | UFOs, UAPs are dominating the media, but what do astronomers really think is going on? Check out our sponsor by using the code coolworlds to get an exclusive 60% off an annual Incogni plan: incogni.com/coolworlds Over the last few years, there has been growing public attention and interest in UFOs/UAPs fuelled by whistleblowers, leaked videos and of course the media. But astronomers have been looking for life in the Universe for decades already, using systematic searches and established scientific methodologies. No-one spends more time looking up and thinking about aliens than astronomers, so what do we think about this? How does science more broadly ingest UFO claims? Today, in the spirit of transparency, we explore this complex and evolving topic...Written and presented by Prof David Kipping.

The Question That Keeps Me Awake At Night Cool Worlds 2023-03-12 | The most fundamental question we can ever ask: Why is something rather than nothing? Not nothing as in no particles or no energy, but nothing as in no space, no time, no laws of physics at all. This is a question that has haunted me for years and today this deepest of questions.Written and presented by Prof David Kipping, edited by Jorge Casas.→ Support our research program: coolworldslab.com/support→ Get Stash here! teespring.com/stores/cool-worlds-store [themed T-shirt for the video is here: cool-worlds-store.creator-spring.com/listing/why-is-there-anything]THANK-YOU to our supporters D.

The Truth About JWST Detecting Alien Life... Cool Worlds 2023-02-18 | JWST is the pinnacle of our astronomical aspirations, the most sensitive telescope ever built by human hands. But can this feat of engineering resolve a question which has haunted us since the dawn of civilization - are we alone? So let's explore whether JWST could detect signatures of biology on another world, and if so under what conditions?
