Cool Worlds

Space, astronomy, exoplanets, astroengineering and the search for extraterrestrial life & intelligence.

The Cool Worlds Lab (http://coolworldslab.com), based at the Department of Astronomy, Columbia University, is a team of astronomers seeking to discover and understand alien worlds, particularly those where temperatures are cool enough for life, led by Professor David Kipping.

    Climate Emergency? Global Sea Ice at Anomalously Low Levels

    This week a plot showing the global sea ice over time went viral due to shockingly low levels, smashing previous records. The plot was so weird that we decided to check out the data for ourselves and see if it was legit. Indeed, we can reproduce this alarming plot and provide some links and scripts for any of you who want to go ahead and try yourselves. Here we get into why we think these kinds of weird observations may become more common in the future. ::More about this Video:: ► National Sea and Ice Data Center archive of sea ice extent data: https://nsidc.org/data/docs/noaa/g02135_seaice_index/ ► My Mathematica script used to generate a confirming plot: https://github.com/davidkipping/seaiceextent ► Two of the first tweets publicizing the viral plot, Zach Labe (https://twitter.com/ZLabe/status/798913080168095744) and Eric Holthaus (https://twitter.com/EricHolthaus/status/800067428419940352). ► Wipneus archive of plots: https://sites.google.com/site/arctischepinguin/home/sea-ice-extent-area/grf ► Eric Holthaus blog article about the viral plot: http://tinyletter.com/sciencebyericholthaus/letters/today-in-weather-climate-sea-ice-tipping-point-edition-monday-november-21th ► Guardian article on record Arctic temperatures: https://www.theguardian.com/environment/2016/nov/22/extraordinarily-hot-arctic-temperatures-alarm-scientists ► CNN article on record Arctic temperatures: http://www.cnn.com/2016/11/18/world/sea-ice-arctic-antarctic-lows/ ► Conrath at al.

    The First Civilization to Emerge in the Galaxy

    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.

    How often does life start on other worlds?

    Astrobiology an exciting new field studying how life begins and the conditions needed both on Earth and elsewhere in the cosmos. Columbia's Director of Astrobiology, Dr Caleb Scharf, dropped into the Cool Worlds Lab to tell us about his new paper which created a "Drake Equation" for abiogenesis. Whilst we can only guess at many of the factors in the equation right now, it provides a framework for tackling this problem going forward. ::More about this Video:: ► The paper by Scharf & Cronin (2016), "Quantifying the Origins of Life on a Planetary Scale": https://arxiv.org/abs/1511.02549 ► Drake Equation explained on the SETI website: http://www.seti.org/drakeequation ► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

    Why Going Faster-Than-Light Leads to Time Paradoxes

    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). → Support our research: https://www.coolworldslab.com/support → Get Stash! https://teespring.com/stores/cool-worlds-store THANK-YOU to our supporters D.

    Can We Engineer The Sun?

    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.
