Katie is a theoretical cosmologist who holds the Hawking Chair in Cosmology and Science Communication at Perimeter Institute. Her academic research investigates dark matter, vacuum decay and the epoch of reionisation. Katie is also a popular science communicator who participates in social media and regularly writes for Scientific American, Slate, Sky & Telescope, Time and Cosmos. She is the author of the book “The End of Everything (Astrophysically Speaking)”
In Sentientist Conversations we talk about the two most important questions: “what’s real?” & “who matters?”
Sentientism is "evidence, reason & compassion for all sentient beings." The video of our conversation is here on YouTube.
We discuss:
00:00 Welcome
01:58 Katie's Intro
- #cosmology  & #astrophysics 
- "The study of the universe from beginning to end from the smallest to the largest scales" 
- #darkmatter, the beginning of the universe & the end of the universe
- Research & public engagement
03:33 What's Real?
- Growing up going to church & youth group & #bible study
- United Church of Christ... liberal & open-minded #socialjustice #lgbtq rights
- Useful guidelines for life but "I never really understood how faith works... believing things without evidence"
- Exploring different religious traditions e.g. #judaism "attending church on Sunday mornings and synagogue on Friday nights"
- "I always wanted to believe something... there's a fundamental urge most humans have to connect with the divine... #spirituality of some kind... the problem was I didn't believe in anything"
- Connecting with religious songs, prayer, rituals about forgiveness & bettering yourself... 
- Being told "just believe"... "I don't know how to do that!"
- "I believe things if I see evidence for them... if I have some reason"
- A scientifically curious kid
- "The way I relate to the world... is through evidence"
- "I don't fundamentally grasp the concept of choosing your perceptions... choosing your beliefs. I don't think I can do that"
- Ontological & epistemological naturalism
- "I haven't had a spiritual experience... I assume I would write it off as something explainable through psychology and physics... but I can't say for certain"
- Enrolling in a #theology seminary school after graduating in physics: "wanting to understand religion... why people believe in things... I dropped out after 6 months"
- "I've done everything... went to every service... went to seminary... I did all the things and still god has not appeared to me in any way... I was a little bit jealous... that certainty, that feeling of peace... you are loved by the most powerful being in the cosmos... that sounds really cool... sign me up"
- "I could follow all the rules... I couldn't believe"
