Project Starshot | New Research on Relativistic Light Sails @CoolWorldsLab

Cool Worlds New research paper from the Cool Worlds Lab about one the most exciting missions ever proposed, "Starshot". Starshot plans to send tiny probes to distant planets beyond our Solar System, the first true interstellar spacecraft. To do this within our lifetimes requires a very fast probe, reaching one-fifth the speed of light. That means Einstein's theory of special relativity starts to become important and so in our new paper, explained in the video, we figured out how much of a difference that makes...

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. Fact checking by Alexandra Masegian.

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/coolworldslab

A 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). Thumbnail image by Zamanday Yolculugunu (www.zamandayolculuk.com)

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...

The Fate of Our Sun

Cool Worlds 2023-06-10 | For billions of years the Sun has been the perpetual, life-giving star in our sky. It's a force of immense power, yet one we take for granted in our every day lives. But like all things, it too must eventually end. Today, we chronicle the future of our home star, its various phases, why this all happens, and the final fate of our Solar System.

An Event So Deadly it Makes Parts of the Galaxy Inhospitable

Cool Worlds 2023-04-09 | 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?

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.

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? Sponsored by Ground News, head to https://ground.news/coolworlds

Earth Over The Next Billion Years

Cool Worlds 2023-01-27 | Our lifespans might feel like a long time by human standards, but to the Earth it's the blink of an eye. Even the entirety of human history represents a tiny slither of the vast chronology for our planet. We often think about geological time when looking back into the past, but today we look ahead. What might happen on our planet in the next billion years?

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? Many have voiced concerns about any programs designed to broadcast our presence - afterall, they may not be friendly. Although it may be a popular idea in science fiction, what do scientists say about this scenario? 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...

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). Special thanks to melodysheep for giving us permission to use their awesome starlifting animations from "Life Beyond 3" (youtu.be/saWNMPL5ygk)

Does Quantum Entanglement Allow for Faster-Than-Light Communication?

Cool Worlds 2022-09-09 | Quantum entanglement allows particles to affect one another faster than the speed of light. So does this mean we could one day build a device to exploit this and enable superluminal communication? A popular trope in sci-fi for sure, but today let's look at the science.

Presented by Prof David Kipping (Columbia). Special thanks to Prof. Ehud Altman (Berkeley), Prof Tim Byrnes (NYU) & Prof. Raquel Queiroz (Columbia) for fact checking our script.

Will We Run Out Of Lithium?

Cool Worlds 2022-08-14 | Lithium demand has been increasing for years thanks to the lithium ion battery. Now, that demand looks set to explode as many nations set new targets for reducing their carbon emissions. Given this, we might well wonder - could we actually run out of the stuff? Join us today as we explore projections for our lithium use and what it all means for the future of our society.

The Wow! Signal After 45 Years

Cool Worlds 2022-06-18 | The Wow! Signal was a radio signal detected in 1977 that remains the most compelling candidate for an alien radio transmission ever received. 45 years later, and after dozens of failed hours spent trying to catch it again, can we conclude the Wow signal was bogus? Join us today as we discuss a new research paper from the Cool Worlds Lab that explores this question and everything Wow.

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. Thanks to Prof Jason Wright for discussions on this topic!

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. Special thanks to Prof Matt Buckley for fact checking and his great blog article that inspired this video (http://www.physicsmatt.com/blog/2016/8/25/why-ftl-implies-time-travel).

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.

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.

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. Today we discuss how we found this object and what it means.

Why We Havent Found Any Earth-Like Planets

Cool Worlds 2021-12-11 | Twelve years ago, NASA predicted around 50 Earth-like planets would be discovered by the Kepler telescope, planets with the same size, warmth and host star as we do. And yet, we're left essentially none. What happened? Why did those predictions not match reality? And what can we learn from these 50 lost dreams...

Is the Solar System Special?

Cool Worlds 2021-11-12 | This video was sponsored by CuriosityStream - sign up for CuriosityStream at curiositystream.com/CoolWorlds to get a year's subscription for $14.99.

Before we discovered any exoplanets, it was generally assumed the Solar System was just a typical planetary system. More and more though, we are finding that the Solar System might not be so ordinary afterall. Join us today as we explore the question - is the Solar System unusual?

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/CoolWorlds

The 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.

The Star That Cant Exist

Cool Worlds 2021-09-15 | Visit our sponsor, Brilliant.org: brilliant.org/CoolWorlds

The cosmos is littered with blue and red stars... but curiously no green ones. Why? Is this a fundamental constraint or merely an unlikely outcome? And what would it mean for humanity if we ever did detect a green star? Join us today as we explore this simple question with major implications.

What If Intelligence Re-Emerges?

Cool Worlds 2021-07-30 | Visit our sponsor, Brilliant.org: brilliant.org/CoolWorlds.

Astronomers are on a quest to search for life in the Universe. Two different pathways lay ahead for this hunt, biosignatures and technosignatures. Today, we discuss the arguments for and against each and consider that intelligence could be a far more persistent phenomenon that we might naively think - with important consequences for astronomers...

Is It Possible to Learn The Language of Planets?

Cool Worlds 2021-07-23 | Could we learn to "speak planet"? Computational linguistics is now found in your smart phone, car and speakers, making sense of our speech and text. Could these same algorithms make sense of exoplanets? Join us today as we explore a radical new research idea recently published by the Cool Worlds Lab. Written and Presented by Dr Emily Sandford. This research was made possible through funding from the Data Science Institute’s Seed Fund Award.

Freakish One-Offs in Astronomy

Cool Worlds 2021-05-21 | Signup for your FREE trial to The Great Courses Plus here: http://ow.ly/x8l230rIoRs - thank you to our sponsors!

New research! One-offs... there's something about them, whether it be the first interstellar asteroid or a star behaving in an unprecedented way. 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.

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. Written and presented by Prof David Kipping.

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. Thanks to Jason Wright and Nadia Drake for help with this video.

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. Thanks to Jason Wright and Nadia Drake for help with this video.

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. Written & presented by Prof David Kipping.

Discovery of a Strange New World

Cool Worlds 2021-02-06 | Perhaps it's a part of what makes us human, to explore the next frontier, to seek out new worlds... Today, we're excited to share a new planet discovered outside of our Solar System by the Cool Worlds Lab - HD 183579b. Join us to hear about the new strategy we developed to find this object, and why this is a particularly valuable planet discovery.
