Episode 185 of the #AskAbhijit show: Ask me interesting questions in the comments, and I shall answer them. A Masterclass on Understanding Geopolitics: Geopolitics From First Principles Enroll here: https://www.ac.university For business/collaboration, email at business.chavda@gmail.com - - - - - - - - - - - - - OUTLINE BY RAMALAKSHMI VV: 0:00 Countdown- Intro Music 1:15 Introduction - Hello Everybody 3:54 Why does inflation (10^-36seconds after big bang) have a high uncertainty? Even after CMBR imaging?.. 15:01 What is cosmic dawn and epoch of reionization in cosmology? 22:50 Under Brane cosmology, how much does sir think the ekpyrotic universe makes sense? Is it supported by Mathematics? 35:14 How does Pulsar Timing Array, someone says he has read a paper about confirmation of gravitational wave background existing in fabric of space.. 42:49 What is oscillating in a matter wave?.. 49:14 Why is the primary focus on reducing CO2 when there are other potent greenhouse gases like methane, nitrogen oxides? How are we addressing the e waste generated from solar technology?.. 56:50 Are there any non human living organism that exhibit suicidal tendencies or engage in self destructive behaviour leading to their own death? 1:02:40 How would the world change if OpenAI or google created AGI today, making them more powerful than governments? What would be the impact on industries, the economy, and society? 1:06:34 Does sir think we can see AI like Skynet which can be threat to us in few years from now as the advancements are very rapid? Dangers of AI.... 1:12:02 Why oceans deep inside are cold but as we deeper in land it becomes hot? 1:16:27 As sir said jet engine development is complicated to develop jet blades from single crystal, if we have rocket tech in isro, high temperature resistant materials are used in rockets, why can we use that in jet engine? 1:22:04 Hypothetically, if we put the entire universe into a large container, what would be outside the container?... 1:24:38 What is anti-gravity? Can it some how exist? 1:25:37 How space looks like, does it look exactly as images released by NASA or will it look different if we see a nebula with a naked eye 1:29:49 What does sir think about possibility of antimatter propulsion for future space travel, and what kind of restrictions does it currently face? 1:31:30 What are god particle and why are they so important to understand 1:33:47 Thoughts on Terrance howard 1:35:12 Someone asks sir to rate khan academy as an educational platform 1:35:36 Do we have any gravitational anomalies discovered on earth just like in movie interstellar? 1:36:40 Are we made of particles or waves 1:37:41 Can sir structure of photon 1:39:17 If light has no mass then how blackholes gravity affects it?? 1:39:59 Have sir watched big bang theory 1:40:15 Why space agencies pursuing a nuclear powered spacecraft? 1:40:55 Have sir figured out new types of battery tech? 1:41:59 Microplastics un avoidable? 1:42:52 How does gravity reacts when we reach absolute zero 1:43:36 Sir's thoughts on Vasuki indicus 1:44:30 Someone says Microplastics are everywhere, bottom of ocean, organs, .... 1:45:31 What is we could transfer our consciousness into an ai model? What makes us human, is it our consciousness or our body 1:48:13 Can humans ever see UV rays 1:48:42 Can neutron stars have habitable planets? 1:50:15 Conclusion- Thanks Everybody
