In this video, John Michael Gautier interviews Duncan Forgan, a postdoctoral research fellow at the school of physics and astronomy at the University of St. Andrews. Forgan discusses his research into numerical astrobiology, which focuses on the study of the origin and evolution of life in the universe. He argues that his top-down approach to planet formation is more realistic and explains a wider range of planetary systems than the bottom-up model accepted by the scientific community. He also discusses the challenges of trying to find signs of intelligent life on other planets, and how technology may improve in the future.

00:00:00 In this video, John Michael Gautier interviews Duncan Forgan, a postdoctoral research fellow at the school of physics and astronomy at the University of St. Andrews, about his research focusing on numerical simulations of protoplanetary disks. Forgan is noted for his research into numerical astrobiology, which focuses on the study of the origin and evolution of life in the universe. He has also appeared in the BBC's "Stargazing: Life in the Sky at Night" and "Horizon: Widescreen Views of the Universe." The public reaction to the discovery of alien life has often been portrayed as negative, but this is not always the case. Forgan discusses the alternative model of planet formation that he developed while working on his PhD, which is based on the idea that stars form not from small bus screens upwards, but from a disk of material that is so massive that planets cease to be planets and become intermediate category objects called brown dwarfs. He argues that this top-down approach is more realistic and explains a wider range of planetary systems than the bottom-up model accepted by the scientific community.
00:05:00 Dr. Duncan Forgan discusses the alternative model of planet formation, which suggests that some objects may lose material and end up being smaller. He also discusses his work investigating whether protoplanetary disks around young stars are indicative of this model.
00:10:00 This video presents the idea that astrobiology can help us solve Fermi's Paradox, which is the question of whether or not there is any life in the universe. Dr. Duncan Forgan discusses his research on the topic, which has yielded interesting results. He also discusses some of the problems with UFOlogy, and how it may not be indicative of anything extraterrestrial.
00:15:00 The author of the article discusses the possibility that space travel, interstellar travel, and even evolution could solve the Fermi paradox. He notes that the paradox is stronger if interstellar travel is difficult, and argues that this could be solved by creating copies of small spacecraft and programming them to be fault tolerant. If this happens, the population would not decline due to running out of food, as it would be a natural event due to the machines no longer following the original program.
00:20:00 Dr. Duncan Forgan discusses the Fermi paradox, which is the question of why we haven't found any alien civilizations yet. He argues that self-replicating probes could easily eat up all of the civilizations in the Milky Way, and that this could lead to a galactic cold war. He also suggests that the solution to the Fermi paradox might be that advanced alien civilizations are too dangerous to exist.
00:25:00 The author discusses the three possible solutions to Fermi's Paradox: rare, maybe intelligent life is rare, and maybe intelligent life is very hard to see. He also mentions that if intelligent life is rare, it may be due to factors like a suitable planet with a large surface area and a thick atmosphere, stable conditions, and a mix of necessary ingredients. If intelligent life is hard to see, it may be due to the many factors that life on Earth has had to overcome. Finally, the author discusses the possibility that if intelligent life is rare, it is due to the earth being a single sample and not indicative of how rare it is in the universe.
00:30:00 Dr. Duncan Forgan discusses the challenges of detecting life on other planets, and how technology may improve in the future. He notes that while the probability of life on other planets may be high, it will take a long time to confirm it.
00:35:00 The author of the video discusses some of the challenges of trying to find signs of an alien civilization. He notes that there are limits to what can be done, and that if one is looking for a techno signature, the chances are better. He also points out that some signatures indicating a civilization could be found in the atmospheres of planets.
00:40:00 Can we solve Fermi's paradox? Dr. Duncan Forgan says it might be possible to see the effects of a mass extinction on the atmosphere, mass extinctions taking a bit longer, and that human-caused extinctions are happening quicker than natural ones.
00:45:00 In his book, "Solving Fermi's Paradox," Dr. Duncan Forgan discusses the idea that intelligent life may have a very short lifespan, as civilizations may eventually destroy themselves. He also discusses the idea that we may be able to detect alien civilizations by looking for remnants of their past, such as abandoned buildings or infrastructure. He concludes that while this may be possible in the future, it is unlikely to happen in the near future.
00:50:00 The video discusses the Fermi Paradox, which asks why there is not yet any evidence of intelligent life beyond Earth. Dr. Duncan Forgan explains that current technology is not able to detect signs of intelligent life, but that this could change in the future. He also explains the protocols that would need to be followed if intelligent life were to be discovered, and the potential consequences should this happen.
00:55:00 Dr. Duncan Forgan discusses the possibility of life existing on other planets in the universe, specifically icy moons in the solar system. If this is true, it would change our understanding of life on Earth as the rarest thing in the universe.

01:00:00 - 01:05:00

In this video, Dr. Duncan Forgan discusses the theory that Fermi's paradox might be solved by understanding the role of chance in our universe. This theory is based on the fact that, although we haven't yet discovered intelligent life elsewhere in the universe, the fact that we exist at all is due, in part, to the chance that we did. Although the possibility of a null result from SETI remaining a net positive for the human species is interesting, the most important thing is that we continue to look for signs of intelligent life.
