Shadow Imaging Boyajians Star Cool Worlds 2018-12-06 | Boyajian's Star (Tabby's Star) has mystified us since we first saw those bizarre dimmings recored by NASA's Kepler Mission. Over the years, people have shown that the data could be explained by comets, or planet engulfement, or even alien megastructures. But here at the Cool Worlds Lab, we had a different idea. Rather than propose a specific hypothesis and see how well it matches the data, why not use the data to reconstruct an image of whatever it was that caused the dimming? Sounds simple, right? Well it took us about two years to crack this damn problem but we're thrilled to finally discuss it with you all in this Cool Worlds exclusive!► Sandford & Kipping (2019), "Shadow Imaging of Transiting Objects", Astronomical Journal, accepted► Background to Tabby's Star by Jason Wright: youtu.be/jjh0oK7ZyfM► Our live Q&A with Tabby Boyajian: youtu.be/k_-6SEb2QlM► "Just a Dust Bowl?" update video on Tabby's Star: youtu.be/D4LIRvGMAVw► "A Theory for Tabby's Star (Without Aliens)" video: youtu.be/risNfZxz6DQ► Boyajian et al.

Direct Air Capture Vs Thermodynamics 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).

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?

Is Messaging Aliens a Bad Idea? Cool Worlds 2022-11-05 | We listen, but we don't send. Why do we expect aliens to transmit if we don't?

Today we explore the arguments for and against messaging, and what it might imply about the type of civilization that chooses to engage in messaging...Written and presented by Prof David Kipping.

Can We Engineer The Sun? Cool Worlds 2022-10-08 | The Sun is dying. A slow death, to be sure, but slowly it creeps towards its end, gradually increasing in luminosity - an effect that will push Earth out of the habitable zone in about a billion years. Can we somehow stop this from happening? Can we save the Earth? Can we save *the Sun*? Join us today as discuss a new research paper from the Cool Worlds Lab at Columbia University, that may help our distant descendants buy themselves billions of years of new life.Written and presented by Prof David Kipping and Matt Scoggins (Columbia).

How Game Theory Can Help Us Find Aliens Cool Worlds 2022-04-28 | Could it be that aliens are trying to communicate with us right now, but we're just not listening in the right way? They might have chosen a specific frequency, time or method of communication that we just never thought to try. In game theory, two players can co-operate towards a common goal even without communication. The idea is called a Schelling point - today we'll explore what this is and how it affects our search for life in the Universe.Written & presented by Prof David Kipping.

Why Going Faster-Than-Light Leads to Time Paradoxes Cool Worlds 2022-04-03 | Is faster-than-light (FTL) travel possible? In most discussions of this, we get hung up on the physics of particular ideas, such as wormholes or warp drives. But today, we take a more zoomed out approach that addresses all FTL propulsion - as well as FTL messaging. Because it turns out that they all allow for time travel. Join us today as we explore why this is so and the profound consequences that ensue.Written & presented by Prof David Kipping.

The Problem With The Rare Earth Hypothesis Cool Worlds 2022-03-10 | The Rare Earth Hypothesis suggests that our planet may the product of an incredibly improbable sequence of events, and thus perhaps intelligent life is extremely rare in the cosmos. Here we tackle this highly influential idea and the arguments behind it. But, digging deeper, we'll uncover some problems with the Rare Earth idea - some of which strike to the very core of our scientific quest.Written & presented by Prof David Kipping→ Support our research program: coolworldslab.com/support→ Get Stash here! teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

The First Civilization to Emerge in the Galaxy Cool Worlds 2022-02-11 | 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: coolworldslab.com/support→ Get Stash here! 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: rand.org/events/2022/03/7-8.htmlTHANK-YOU to our supporters D.

We Discovered a New Exomoon Candidate!! Cool Worlds 2022-01-13 | Exciting new result from the Cool Worlds Lab! Several years ago we started an ambitious research program to survey the sample of transiting cool, giant planets for exomoons. Our search is the first of its kind and provides one particularly interesting result - a new exomoon candidate, Kepler-1708 b-i.

Are Alien Lurkers Watching You? Cool Worlds 2021-10-08 | Visit our sponsor, Private Internet Access to get digital privacy for $2.08/month: privateinternetaccess.com/CoolWorldsThe search for alien intelligence is usually a framed as a search for life around other stars. But some have suggested that we should look within the Solar System instead - seeking so-called "Lurkers", alien probes sent here to monitor us. Today we explore this interesting idea, the motivations behind it and where we might actually try surveying.Written & presented by Prof David Kipping→ Support our research program: coolworldslab.com/support→ Get Stash here! teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

These "black swans" capture our attention and imagination but interpreting them is challenged by the inherent scarcity of data. Perhaps no case encapsulates this more than the famous 1977 Wow Signal. Join us today as we discuss our new paper on Black Swan Theory with consequences for the Wow signal.You can support our research program and the Cool Worlds Lab at Columbia University: coolworldslab.com/supportGet Stash here! teespring.com/stores/cool-worlds-storeThank-you to our supporters T.

A MILLION MPH Cool Worlds 2021-05-01 | How fast are you moving? Remarkably you are moving, by some definitions, around a million miles per hour. But, why don't we feel this motion? Is this speed useful in some way? And what does the question of speed really even mean? Join us today as Cool Worlds explores our motion through space.

The Birth-Death Drake Equation | Part 2 of 2 Cool Worlds 2021-04-02 | Welcome to Part Two of our deep dive into the Drake Equation. In the second part, we explore the temporal aspect of the Drake Equation and how it illuminates a path towards an alternative formalism - the Birth-Death formalism. Join us as we move forward to the bleeding edge of modern research on the Drake Equation. Written and presneted by Prof David Kipping.

The Drake Equation After Sixty Years | Part 1 of 2 Cool Worlds 2021-04-02 | Sixty years ago Frank Drake wrote down an equation that has become one of the most famous in astronomy - the Drake Equation. This formula, aiming to estimate the number of alien civilizations communicating within the galaxy, has been celebrated, abused and criticized. Today, we are taking a deep dive into this special equation in a two part special. Written and presented by Prof David Kipping.

Why Martian Canals Still Matter Cool Worlds 2021-03-03 | A century ago, many thought Mars was scored by a canal system constructed by an advanced civilization - an idea championed by astronomer Percival Lowell. Why? How did an astronomer come to this conclusion? Today we explore the canal phenomenon and discuss why it's a crucial allegory from history - pertinent now more than ever.
