But chinks in the armour have been developing, such as the Hubble Tension. Now, however, a new result threatens to completely upend our view of the Universe - we no longer even know how it will end.Written & presented by Prof. David Kipping.→ Support our research: https://www.coolworldslab.com/support→ Get merch: https://teespring.com/stor...

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: https://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...

Thanks to Opera for sponsoring this video. Click here to upgrade your browser for FREE! - https://opr.as/Opera-browser-coolworldslabSo the whole world seems to have become very excited about the claim of a biosignature discovered in the atmosphere of the exoplanet K2-18b. And no sooner did those headlines hit the airwaves, astronomers came out in droves expressing skepticism and concerns. It feels a bit confusing to have two sides so certain of their position, and often the truth is more nuanced than either side will concede. So today, we're going to take a...

Many of you wanted me to talk about the Dark Forest Hypothesis - an idea popularised (bit not limited to) the the sci-fi novel and Netflix series, "The Three Body Problem" by Liu Cixin. So in this video I'll explain what dark forest says and why I don't buy it. (Note - this is *not* an analysis of Cixin’s story beats set in his fictional universe, but rather the concept of dark forest in our real one! Although, I will refer to the al...

Light sails are a promising method for traveling through space - indeed, Breakthrough Starshot proposed a laser driven version could reach nearby stars. But the exorbitant costs and engineering challenges of such a proposal have stymied its realization. What if there was a way of using the Sun - no lasers required - but keeping our dream of interstellar travel in tact?

To celebrate the release of Star Wars Rogue One this weekend, let's ask the question - could we detect the Death Star with our current telescopes? Remarkably astronomers have been thinking about the detectability of alien megastructures, such as the Death Star, for many years and we can apply some scientific thinking to get to the answer.::More about this Video::► Companion video on Martin Archer's channel, "Is the Death Star a Star?": https://youtu.be/Q4CKSekJzxk► Kipping & Teachey 2016, "A Cloaking Device for Transiting Planets": https://arxiv.org/abs/1603.08928► Cool Worlds video by Ale...
