She’s igniting my desire to go back to school and learn science in a more formal way. I think about this stuff daily but I have very basic understandings and keep pausing the video to research terms you use, and concepts I am not familiar with. this woman is really hitting me in a personal place with her mind and how she thinks. I am mesmerized with the subject matter and her profound thoughts and understanding. I’m in awe of such intelligence really. And you too Lex, brilliant, you have such an amazing understanding of so many subjects and I love the summaries of your guests answers you give as a response they really aid my understanding of the content. You push my boundaries with your podcast and I think you ask the best questions.

I love her approach to the podcast, the way she lays out thoughts and how open she is, and how deep she’s willing to get into it. Love for Lex who’s so curious about many things and shares it with us in this way!

Sara is brilliant and I like how Lex just lets her speak and lay down her theories and findings! She's as much a philosopher as she is a physicist.

I love… love how Lex intertwined his experiences with his perception of the universe with us.

Lex! I don’t know what it is, but I totally appreciate seeing how you interact with your guests. You treat people with astonishment and they appreciate it, and give you their best ideas. I absolutely adore every concept you guys are discussing here. Such an example of the gems that exist in our understanding of the universe. Thank you both. ✌️❤️

I have to watch this in bits..... As my brain starts melting 😂... Give it a few hours rest and continue. So amazing and articulate. Such a beautiful mind❤

Sarah, here I am unloading from my truck a mass of soil (and giant soup of life forms wriggling digging decomposing) and compost that I collected on the side of a mountain road at the base of sloughing cinder cone on the big island Hawaii and I'm finding it difficult to continue to muster the"mana"to keep shoveling because the sound of your voice is so soothing. It's not just a sound though it's also what's spewing from your brain! Come visit! Aloha!

“We are really good at identifying things as other, we’re not really good at understanding when were the same or when were part of an integrated system thats actually functioning together in some kind of cohesive way.” So true, and deep.
