what she just said... She just said that we think there's a supermassive black hole at the center of every Galaxy and then before that she stated but there's there's no black holes in our universe. Am I a misunderstanding Galaxy and universe? Did I instead mean to say solar system? Did she mean to say solar system? Cuz I don't think she said that. Like what am I missing here because it doesn't feel right the things that she's stating and the lining up of it all...

so it’s like the ocean, sharing through the waves and assisting change and potential. What i mean is that the black hole generates a stable turbulence or the turbulence is in a state that’s stable even though it’s not still. Nature would naturally ride the waves or listen to the waves, all natural responses to the, a relative. - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

black holes are like washing machines. Drop a load in, gets rattled, washed and ejected. There’s no permanent inside because the stuff is torn apart faster and faster breaking you down naturally or a planet but making a lot of noise and jumping around making waves and shooting that broken down matter out or leaking it slowly during the stable period that isn’t eating. It’s more like the thing Thai chi masters do with their hands, the spinning and then release in front of the body. It’s like you can naturally feel the differences in energy and share with it not push or pull but become a ramp for it to roll. So if the inside of the black o hole is empty then it might be so empty it sucks in and tears apart and shoots it out like a slide or ramp or the natural slide in and change and slide out. Almost like a Mobius strip but in a different form. - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

So there can be super massive black holes. But she's saying that no, they're not affecting us at all like because we in our little micro universe haven't seen them in enough of our universe yet... But you're literally talking about how you wouldn't even notice if you were affected by them because they could be so big that it's just so slow.

what she just said... She just said that we think there's a supermassive black hole at the center of every Galaxy and then before that she stated but there's there's no black holes in our universe. Am I a misunderstanding Galaxy and universe? Did I instead mean to say solar system? Did she mean to say solar system? Cuz I don't think she said that. Like what am I missing here because it doesn't feel right the things that she's stating and the lining up of it all...

I'm very curious about this "foisting" of relativity as relativism on culture, because I've heard people (and books, documentaries, etc.) seem to conflate the two as though Einstein was advocating for relativism (social, cultural, moral) through his theory of relativity. He may very well have been a relativist, but those don't seem to connect for me. - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

Skipped to ER = EPR () immediately (will listen to the full thing later). It's incredible how someone who has truly mastered their subject can explain its concepts in such a simple way. Excited for this one! - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

I don't understand why they can't accept that. The wormholes are quantum entanglement... I literally don't understand what the difference is. Maybe they need to catch up or maybe I need to learn more about how they're defining it but for me I see them as the same thing - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

this part right here to me seems to connect the theory of entropy and the inflation of the universe to the information loss paradox of black holes. - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

but with one data point. If there are 7 centillion stars and life is one in 7 centillion then we are all alone.  You said yourself we don’t know how it started and we definitely can’t duplicate it.  We know milliseconds after the big bag but don’t know how we went from “rock to Rachmaninov” - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468

maybe life isn’t that rare but consciousness is a great hurdle. Life came on fast but consciousness took 5 billion years. I think we are rare or 1 of 1.  How did we not get hit with a medium size asteroid in 5 billion years? I think we are the flip a coin 100 times and got heads 100 times type chances. - Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468
