Guest bio: Sean Carroll is a theoretical physicist, author, and host of Mindscape podcast.
I imagine Sean Carroll walking his dog and saying, "The reason I get to walk you rather than you walk me is that I have the ability to imagine counterfactual hypothetical futures."
...and his dog looks up and thinks "whatever, my ancestors crawled onto dry land at the same time as yours, and I trained you to give me treats just by doing your dumb tricks"
Lol
I read it with Sean's voice in my head
Fin and jake
😂😂😂
That's interesting how thinking would change in land, as opposed to being under water.
This guy sounds identical to Robert Greene
Greene's voice is much raspier
@@verrico7536 yeah definitely. Younger Greene tho and it’s mainly the inflections of how they speak
With a little less bullshit
🙏🙏🙏🙏🙏 fries my tiny mind.. , I seem to get a bit of it each time I re watch😂🙏🙏🙏🙏
It should be possible to map out the entropy of a single particle, right?
No, entropy refers to systems. A particle is a fixed structures, it cannot contain different levels of order. Also entropy is not an absolute measurement, it rather compares two different states of a system relative one to the other.
@@AlexandrosSandros what about virtual particles? Do they really become particles under the right conditions?
@@Killer_Kovacs I really don't know that. It's an interesting question
my head hurts just thinking about the video
Stars don't end up as brown dwarfs, Sean, that's a planetary designation. Will give him that slight lapse though 😜
I kept telling people that Uranus is a brown star, but everyone looked at me weirdly.
it makes sense that black holes would have high entropy. Look at it this way ... no matter which microstate the matter inside the event horizon is in, as long as the density of matter is high enough to make it a black hole, the macrostate will be a black hole. Hence EVERY microstate leads to the same macrostate. Meaning that the macrostate which is a black hole has the maximum entropy possible.
Entropy is a measure of a systems disorder. More disorder the higher the entropy. It sounds to me that blackholes should be at the lowest entropy in relation to our universe. The matter inside of the blackhole could be whatever idk. Could be at the highest entropy like a quark smoothie, or lowest entropy like a like some kinda perfect crystal of matter, or neither. Could all happen transiting the event horizon.
You can have closed systems, like a closed room. Who's the air molecules in the room are sealed off from the outside. Inject colored smoke in a corner. Starting out it's lower entropy because it's high entropy state is all the smoke particles and air particles mix thoroughly on they're own. The stablest configuration. Now open the door to the hallway and the rooms air is starting at it's lowest entropy as is the hallways air of the room air hallway air system. Is this wrong?
Thou they have someways to calculate the entropy in blackholes and it seems plausible anyhow.
@@jasonbrady3606 The mathematical definition of entropy is Boltzman's constant times the natural log of the number of microstates that give the equivalent macrostate. By that definition, a Black Hole has the maximum possible entropy because every microstate of the interior of the black hole gives exactly the same macrostate - namely, a black hole.
@@aaronwolbach9880 yes he explained it well.
@@aaronwolbach9880 I think I've seen it derived a different way, directly related to the scharwarts jfield radius
It could have been the maximum amount of entropy, ultimately. The actual equation is quite simple, and seems to have a hyperdimensional connect thought he would illucidate
Lex: What does the landscape of entropy in the universe look like?
Sean: Entropy is hard to localize, it’s a property of systems, not a parts of systems, right..
Me: …right..
This guy loves to take his final syllables for a walk
They should teach physics in school…., oh wait.. the poor buggers tried to😂
WTAF #### IM BAFFLED
wow
There is always preconditions to every theory. Complexity lies in the preconditions, which just kicks the can down the road.
no. that's exactly wrong.
The only difference between humans and animals is the ability to feel the Time dimension. And this has resulted in humans forming various languages. Think about it, without sensing time, there is no need to form any language!
3rd!
3rd what? Sean is musing the second law of thermodynamics, essentially move to disorder or entropy.
Another clip where Lex seems incapable of listening to the person he is talking to. Sean Carroll explains something that he was asked about. Lex then responds with "I wonder how [insert what was just explained] looks like". This is exactly why I never could sit through an entire podcast. This dude is so inside of his head and stuck with his ideas that he can't hear what the other person is saying to him. It's okay in general and I like his enthusiasm and curiosity, but I just can't sit through it lol. Great guests but I'd rather see them on Joe Rogan compared to this shit. Sorry but that's how I see it. I genuinely hope Lex finds a way to not do this in the future and do better.
Feel the same way. Really good in the short clips but I have a hard time listening for more than 10 minutes
@@kevinconroy6606 Yep. And for context I'm someone who could sit through an entire Sam Harris podcast regularly (before 2016 election of Trump, then he went off the rails too lol). I appreciate what Lex does but I think he got too big too fast before he figured out how to refine himself and what he's doing.
