I find it hard to believe the fact that this channel doesn't have a million subscribers.

[tiberiusgracchus]

that is a sick count chocula/black metal organ riff that hits around 33:00

for real though, JMG's content is phenomenal.

[madmattdigs]

One of my favorite channels. Maybe my all time favorite. Excellent content.

If the universe wants to divide by 0 don't judge it guys

I could listen to Professor Lewis all night. He's so engaging and makes everything easier to understand. ❤

[dancingwiththedogsdj]

The separation of disciplines is EXACTLY what A.I. should be perfect for, being able to find relationships in the data that we simply cannot keep up with. It'll be interesting to see what the future holds! Fantastic video! 😊🌎❤️🕺🏻🐶🚀🖥️

+1 for The Prisoner. My parents turned me on to it as a kid. What a masterpiece.

Maybe this is why I, an integrated circuit "chip" layout designer, haven't found work since January.

Terrific episode! I'm always stoked to hear Dr. Lewis. If he's reading the comments, please give us another episode of Alas, Lewis and Barnes! ☄🌌🔭😎🙌

I'm so glad you asked about why physicists are so afraid of infinities. As a laymen, I can't help that infinities are something we just have to learn to deal with, even if we have no hope of comprehending them.

The TV story mentioned at 55:30 is from a book of short stories I read many years ago - it may have been Asimov (because it was about robots), or someone like Poul Anderson (because i read lots of his stories), but the conclusion was excellent - the hero, despite being afraid of punishment if discovered, got his domestic robots to do the consuming for him. What he hadn't considered was that all the robots shared information. Happily, the authorities recognised it as a brilliant solution they hadn't thought of and he was well rewarded!

Great episode and wonderful interview. I like how you moved from the topic of the Universe's characteristics to other realms of physics and then ended up discussing AI. It not only flowed well, but it was very easy to digest. Excellent presentation all around John.

When I think of a metaphor for our expanding universe, I think of an air bubble rising through the water. As the pressure of the water decreases the volume in the bubble (and therefore the area of the surface of the bubble where we live) expands. But this leads to disquieting thoughts about what happens when the bubble reaches the surface of the water.

I very much enjoyed the part about how Lewis and John keep their knowledge up to date. It inspired me to be more methodological about how I keep my own professional knowledge up to date. Thanks Event Horizon, for the rest it was all very entertaining as always.

Really great episode and fantastic interview. Hope we get Prof. Lewis again in EH, in nearest future. Thank you.

19:01 || I think the prerequisite of being a professor of astrophysics is saying you have to be careful. I don’t think it’s a science of caution: I have no problem with the infinite. Raised a Christian Scientist with the emphasis on science. Visible and Invisible Quantum Oceans / Waves breaking at irregular universe boundaries.
If oceans are flat, Quoceans are at minimum 3D. The universe is still creating itself. [I thought of this at age 12 (1967), and I have changed my mind very little since then. I’m not saying why or what it is, I’m just saying what it looks like. It’s gorgeous! The biggest surprise is it moves gasses — possibly air — some within the human hearing range]

[linesided]

Oh I love it when a rational mind takes dark matter out behind the woodshed.

[Mandrak]

I was enjoying every second of this interview. Great discussion.

[arvid]

Thank you both for a splendid interview.

[FesteringGhoul]

I love the idea that we should not like the word "infinity" in any astrophysical and cosmological contexts. It just firmly pushes back on any legitimate speculation the universe might go on infinitely.
