I'm a big fan of How the Universe Works and am very excited to find out you're on YouTube as well! Out of curiosity, do you know where someone (non-scientist) could go to share their theories and ask questions on things like the expansion of the universe or quark behavior?

Happy 200th episode "anniversary" Dr Sutter! Here's to 200 more, may the library of your episodes continue to expand for as long as The Universe does! I think I started listening to you sometime around episode 22 "Question Bonanza", then went back and listened to everything before, read your books as they came out along the line, and have been hooked on your content ever since 2015! My favorite topics of yours over the years have been Brown Dwarfs, James Clerk Maxwell, the "what is" series on Gravity, the Astro101 series, Spectroscopy, Stellar Nucleosynthesis, and of course the resultant Supernova once SN "goes too far". May the awe never end, thank you!

Happy 200th!!! The biggest mystery to me is what is my dog thinking when he looks at me watching these podcasts!! 🐶 To me Dark Matter is the just finished reading an article about Venus in Astronomy magazine and it got me thinking how amazing that would be to see remnants of a city buried under the landscape before the Venusian oceans dried up and the world went runaway greenhouse.

Didn't get my notification for this episode. Glad I checked subs to hear it.

If gravity is a result of space-time itself, What if we stop trying to quantize it?

A Bi Centennial of podcasts; nice one: and a plausible explanation for those tem minutes could take a little longer than 10... 🤔{\} 🙃
