- Episode highlight --- Black hole mergers emit gravitational waves, not light, audible in space
is this the low freq noise people are complaining about?
I seen the title and said “ you don’t have to tell me twice” CLICK 👍🏾
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.
% of what she was talking about (but really would like to, as the topic is super interesting) and I’m only through the episode.
If ppl believe all this and take time to study it they should believe in demons, warlocks, witches, sorcery and God.
What is being described at gives meat to what she described as the 2 particles being separated at the event horizon. In that one particle appears inside and one gets radiated. The particle inside becomes part of the hologram, the other weightless and lost.
Mother of all tinnitus.

This does sound fascinating! It’s am as I watch this episode hahaha. Kindred spirits indeed. 🕊️💜🕊️
am haven't slept yet. Better watch some Lex to slow down my brain. And then you open with the 9am joke! Thank Lex, making the world a smater place!
So the black hole is the diode of the space circuitry?
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.
i think the black holes are like is a mobius event.
- Formation of black holes
- Formation of black holes --- Black holes form from massive stars collapsing, leaving only gravity
Perhaps our beautiful star in the sky that warms us daily is the backend of your nothing..& is looking at us all here on Earth .💫
- Finally I get to correct a real icon of astrophysics! It will collapse under its own mass not under its own weight. BAM!
electrons get jammed into the protons?

- Oppenheimer and the Atomic Bomb --- Scientists' moral dilemmas, geopolitical impacts, and America's unique scientific environment
did he say “World Leaders for Homeless Technology”? 😂😂😅
Technical note: at approx minutes, lex asks about the Americans Vs Nazis Vs Russians as to who could build the first bomb. As a physicist, please don't forget the other Europeans who were instrumental in making many of the theoretical calculations! A lot of the fundamental work was made in Britain, Italy, and Hungary. Think of people like Enrico Fermi...
the 33% definitely used it 🙂🙂🙂 no Would, ifs or buts
At or so Janna says exactly what I was thinking about the US and how we actually had the best chances of getting the bomb first
We’re losing that in the US Lex. And your buddy Joe Rogan bears a lot of responsibility for that by endorsing Trump.
It's interesting how it's all Western countries, with the exception of Japan, that lead with the number of Nobel prize winners.

- Inside the black hole --- Space and time swap roles; singularity becomes inescapable future point
It's finally finally someone answers this question for me. I am so grateful I have taken time to watch this. So far I have always wondered, would we see other particles? Would we see the Galaxy behind us? Would we see infinitely behind us? Would we see other things? But at least I know we'll see light.
- Supermassive black holes
- Supermassive black holes --- Formed from primordial collapse, crucial to galaxy formation, not star mergers
" we don't think that our universe is old enough to have this happen yet" 'all realize that our universe is like a block in a city, right!!!!?!!;? That doesn't make any sense to me... 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. So what the f*** is that s***!???

- General relativity --- Einstein's theory links matter-energy distribution to spacetime curvature, predicting universe expansion
I haven't seen anything repeat yet. in myself. Hm.
dark matter moves space time 😮
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.

- ER = EPR
- ER = EPR --- Quantum entanglement links black hole interiors to Hawking radiation via wormholes
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!
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
- Firewall
- Firewall --- Firewalls challenge smooth event horizons, suggesting quantum threads underpin spacetime
- “I’ll entertain pretty weird things…”
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.
So...if gravity is emergent from quantum properties, is time still emergent from gravity?

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”
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.

's game developers this is gold. I like what he said at . It seems that game dev could go the way of YouTube. I find YouTube superior to television or even movies because it provides custom content for different groups, unlike mainstream media that provides one size fits all. Video games could do the same, specially low budget indie games.
niche success , then reinvest

i remember loving CompUSA or whatever major retailer for PCs bc they'd have demo computers that always had wolfenstein, it was the best thing I'd ever seen and I've been a die hard FPS player ever since.

I was curious about the math in the graphics processing at
This is incorrect. It's called inpainting and has been around for a while now.
Very sensible advice for cutting through AI hype at that Lex would do well to take "everybody whos looking at this topic should actually try using the coding assistants on hard problems and see how they do there"
- Simulating reality
- Simulating reality --- Realistic human simulation remains challenging; ethical concerns about AI suffering arise
Having spent my PhD doing atomistic simulations, I don't have much patience for this type of talk... NOTHING in our reality can be fully simulated... faked, yes, maybe in some instances to the point of being indistinguishable from reality. But physics tells us that—IN PRINCIPLE—it's impossible to fully simulate the behavior of even a single electron, let alone an atom or a molecule... so talking about this in terms of the whole universe is beyond absurd. This is also closely related to the concept of computational irreducibility Stephen Wolfram talks about... do you want to fully "simulate" the behavior of atoms? Great, you need *atoms*. Anything less than that won't cut it.
regarding "Simulating reality",ask yourself, "have I _ever_ seen _anything_ *GLITCH* into or out of existence?"This might be happening at the absolute smallest level of quantum physics,but at the macro level?...There are asteroids, stars, and planets that are surely of far greater importance.
Shame sesame wasn't mentioned at around .
- this is basically what John Horton Conway talked about with "The game of life" - which has been talked about a lot in this pod earlier. Rest in peace.

as a gamer, that sounds awfulnot only that complete stylistic confusion, everything just becomes one big mush,why do they always seek to mainstream everything? unity had the same customer tracking systems in development, so they can track, exploit and monetize and datahoard the playerbase and keep them in their ecosystem like cattle, uff
Lex: apologizes for asking a stoner question.Sweeney: “No, I’ll knock your freaking socks off with this idea”
