It's getting harder to harder to ignore the potential disruptive power of AI in research. Scientists are already using AI tools but could the future lead to complete replacement of humans? How will our scientific institutions transform? These are difficult questions but ones we have to talk about in today's episode.Written, presented & edited by Prof. David Kipping.→ Support our research: https://www.coolworldslab.com/support→ Get merch: https://teespring.com/stores/cool-worlds-store→ Check out our podcast: www.youtube.com/@CoolWorldsPodcastTHANK-YOU to T.

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 Alex Teachey about our laser cloaking system: https://www.youtube.com/watch?v=z1Pqqf_6J9w► Most recent results from exomoon hunting, Kipping et al. 2015, "The Hunt for Exomoons with Kepler (HEK): V.
