THANKS FOR WATCHING!!Direct Air Capture Vs ThermodynamicsCool Worlds2023-09-19 | 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.

#astronomy #jwst #exoplanetsWhats Stopping Us From Building a Warp Drive?Cool Worlds2023-08-01 | 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?

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...

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...

#DarkForest #SETIParadox #CoolWorldsCan We Engineer The Sun?Cool Worlds2022-10-08 | 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.

#MoonMoons #SubMoons #CoolWorldsJWST First Color ImageCool Worlds2022-07-12 | ...The Wow! Signal After 45 YearsCool Worlds2022-06-18 | 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.

#WowSignal #AreWeAlone #CoolWorldsWhy Starship Could Transform AstronomyCool Worlds2022-05-27 | SpaceX's Starship rocket is nearing first orbital tests. This Super Heavy launch vehicle promises to lift enormous masses into space, and do so at far cheaper costs than the competitors. What could these capabilities do for astronomy though? Join us today as we explore the potential transformative power of Starship for astronomy.

#SpaceX #Starship #CoolWorldsHow Game Theory Can Help Us Find AliensCool Worlds2022-04-28 | 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.

#SchellingPoints #AreWeAlone #CoolWorldsWhy Going Faster-Than-Light Leads to Time ParadoxesCool Worlds2022-04-03 | 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.

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.

#RareEarth #AreWeAlone #CoolWorldsThe First Civilization to Emerge in the GalaxyCool Worlds2022-02-11 | 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.

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?

#SolarSystem #AreWeUnusual #CoolWorldsAre Alien Lurkers Watching You?Cool Worlds2021-10-08 | 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.

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...

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.

#BlackSwanTheory #WowSignal #CoolWorldsA MILLION MPHCool Worlds2021-05-01 | 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.

#DrakeEquation #AreWeAlone #CoolWorldsThe Drake Equation After Sixty Years | Part 1 of 2Cool Worlds2021-04-02 | 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.

#DrakeEquation #AreWeAlone #CoolWorldsWhy Martian Canals Still MatterCool Worlds2021-03-03 | 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.
