How to Flip a Planet

It’s possibly the most famous question in all of science - where is everyone? Join us today for deep dive into Fermi Paradox. 🌏 Get exclusive NordVPN deal here ➵ https://NordVPN.com/coolworlds It’s risk free with Nord’s 30 day money-back guarantee!✌The Fermi Paradox has been a topic of keen debate amongst scientists, astronomers and the rest of us for more than seven decades. We can't resist the urge to speculate about aliens! But what is the paradox even really about? What explanations have been offered? Today, we explore this famous question, and offer a mind-shifting explanation.Written and presented by Prof David Kipping.→ Support our research program: https://www.coolworldslab.com/support→ Get Stash here! https://teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

You've probably heard about the recent news of the strange dimmings of Tabby's Star and the provoactive hypothesis of an alien megastructure (fi not check out http://bit.ly/TabbysStar). But could there be a natural explanation instead? Well two theoretical astrophycistss here at Columbia think so and here they briefly summarize some of the leading theories (although news ones are appearing almost every day!) and they think their own explanation is the best one so far.::More about this Video::► Metzger, Shen & Stone (2017), "Secular Dimming of KIC 8462852 Following its Consumption of a Planet": https://arxiv.org/abs/1612.07332► Montet & Simon (2016), "KIC 8462852 Faded Throughout the Kepler Mission": https://arxiv.org/abs/1608.01316► Schaefer (2016), "KIC 8462852 Faded at an Average Rate of 0.165+-0.013 Magnitudes Per Century From 1890 To 1989": https://arxiv.org/abs/1601.03256► Boyajian et al.

Until recently, it was thought that travel through a wormhole, like that seen in the 2014 Christopher Nolan film Interstellar, was forbidden by the laws of physics. Prof Daniel Jafferis and his team have recently had a breakthrough and found a way to make it physically allowed. Prof Jafferis dropped by the Cool Worlds Lab to tell us about this fascinating idea.::More about this Video::► Gao, Jafferis & Wall (2016), "Traversable Wormholes via a Double Trace Deformation": https://arxiv.org/abs/1608.05687► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk::Playlists For Channel::Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorldsCool Worlds Research ► http://bit.ly/CoolWorldsResearchGuest Videos ► http://bit.ly/CoolWorldsGuestsQ&A Videos ► http://bit.ly/CoolWorldsQAScience of TV/Film ► http://bit.ly/ScienceMovies::Follow us::SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribeCool Worlds Lab http://coolworlds.astro.columbia.eduTwitter https://twitter.com/david_kippingInstagram https://www.instagram.com/cool.worldsTHANKS FOR WATCHING!!

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.
