2:45:30 Light reflected off a mirror doesn't involve absorption and re-emission of light. It's a scattering process. Fluorescence involves the absorption and re-emission, and this has no preferential angle.
To give another explanation of why time reversal doesn't reverse the direction of forces: Acceleration is the second derivative of position with respect to time d²x/dt². If you change to t'=-t, then you can calculate the new acceleration d²x/dt'² , and we get two minus signs from the chain rule (once for each time we differentiate by t'). So it cancels, and the acceleration is invariant
I dont know if you read these, but. I think a lot of people would be extremely interested in a podcast with Demis Hassabis. I think he is different from the other ML guests you have had and id be interested to hear his ideas on ML applications to physics, especially since his goal for ML is to better our scientific knowledge. Of course I dont want to make it seem like i am demanding anything, so only if it seems like something you would be interested in. But he is an expert in neuroscience, AI, and he does have experience interacting with scientists/philosophers. I'd love to see you two brilliant minds interact. Thanks for these great podcasts Sean!
I personally love the long answers and long podcasts like most people probably do. But the dumb questions are usually entertaining if they are funny and the dumb physics ones really really help people that are trying to learn. Not everybody is a graduate student! I know I have personally learned a ton from questions that many would consider dumb. I'm sure you can parse out the really awful ones unless they're funny. I would say a combination of the top 100 best questions with as long answers as possible would be perfect. Take a few and do them really long and keep the worst ones really short. Thanks for everything!!
Also, having basic stuff repeated is a good reminder even if I've heard it a million times. There might be a tag or footnote that is awesome. It also really helps to figure out how to break down an idea or ask the right question.
We are at the center of the universe, because since the universe is not expanding into anything, the entire universe is the center of the universe, the same as saying that every point in the universe is the center. Some things are hard to express without circular logic.
Sean, I have a good question I’ve never heard addressed. Does the double slit delayed choice quantum eraser make worlds re-cohere when the quantum information is erased?
The answer is yes, or you could say that worlds that have a significant chance of re-cohering aren't technically worlds yet. He refers to this situation at 1:21:38 as "If you can undo it, it’s not a measurement". Measurements only have outcomes because there's a stable world where that outcome is descriptive of the behavior of things in that world. If that's no longer the case, the concept of distinct worlds or measurement outcomes doesn't really apply to the wavefunction in that case.
Professor Carroll, Thank you for your contribution in popularising all the wonderful concepts modern physics was able to procure. Using the occasion I'd very much like to hear your thoughts about the nature of spacetime.

2hrs 45: If anyone wants a simple but comprehensive answer to this question (why are photons reflected at an angle equal to the angle of entry by a mirror?) - Richard Feynman used exactly this an an example to show how QED can explain the behavior of light in his book QED - the strange theory of light and matter, which he wrote for an interested layman audience. It's the first 10 pages of chapter 2: Photons - Particles of light. There's no way to squeeze the answer into a TH-cam comment, I'm afraid.
Is time the result of (i.e., emergent due to) motion? Or, does time exist before motion (perhaps 'potential time', akin to potential energy?) which allows motion and change to occur at all in the first place? If all motion (including motion of all subatomic particles, etc.) were to somehow freeze, would that mean time would freeze; and then when things start moving again time exists (results) again? Or, is time related to degrees of freedom (to move or potentially move) in 3 (or more) dimensional space? Or, none of the above?
I appreciate the hard work and effort you put in to these, Sean, but how you dismissed one of the first questions regarding how long would it take our fastest rocket to pass Voyager I was, well, lame and downright pompous.

Hope you don't mind if I post this on your site since I was hoping to get feedback from people like you with regards to one of my crazy ideas: So here goes: If and when we leave this Earth it would be very helpful if we could communicate instantaneously back to here or wherever else we end up being. Sound nuts right. Well maybe not. Here is part of what I have in mind. Since Entangled Particles seem to be connected in such a way that each knows instantly, the "spin state" of the other twin ,at least for this discussion lets suppose they do. Then here is my thought. What if every mission into deep space were to carry with them a device that contained some number of Entangled particles that were initially entangled with their entangled twins at their point of origin. Then if it were possible to construct within that device a method wherein they could be arranged, for want of a better word, into a position or state such that they could be encoded with binary states that could be altered then maybe messages could be sent from place to place seemingly instantaneously. I say "seemingly" since it may be that what we see as instantaneous may not in fact be instantaneous when our methods of measurement progress to a point where we can be more precise.Think of up/down as 0/1.if that helps.For all you Star Trek Fans who understand Binary, think of a light board with only red/green lights fixed behind it. At each position on the board the light could be either one or the other now picture the spin of the "up" particle being"red" and the "down" spin being green. then it should be possible to encode the msg in binary on the entangled particles at one location and that msg would appear instantly on the remote board where the device containing the entangled twin particles was located......Maybe. Maybe a primitive form of this device could be tested on the Space Station to verify my hypothesis.

I have become extremely jaded with mainstream Academia. First I was forced to suppress my Mathematical intuition. I could jump from step 1 or 2 to 10 intuitively. I didn’t receive any marks for that. I was disciplined. Forced to believe memory storage and recall is intelligence. This is a great disservice to Humanity. A down right crime against Humanity. We will suffer immensely if this is not corrected sooner than later.
@Anthony Chen-Kerbowitz I am trying to make a clear distinction between what’s called as Intelligence and what’s called as Memory storage and recall. Point is *** WE Have confused the ability to store memory and recall it....IS NOT INTELLIGENCE!!! There are 7 faculties in the human MIND not brain. Intelligence is one. Memory is another.... we have CONFUSED the ability to memorize and recall memory with Intelligence. This is the great disservice to humanity. THIS IS IT.... You can ONLY recall memories that you have accumulated with 5 sense organs. INTELLIGENCE-INTUITION Allows you to jump from step 1 to the answer. NOT USING MEMORY Using INTELLIGENCE. NOW THAT IS REAL INTELLIGENCE. MEMORY and the ability to recall ***IS NOT INTELLIGENCE *** Even though we learned that in school. Do you get it? I am not trying to belittle anyone Or attack. Simply inform and share THE FACTS 7 faculties in human mind Intelligence is one Memory and recall is another. These are scientific proven facts. There are many dormant sub groups But that would get confusing.
@Anthony Chen-Kerbowitz Rananajun....the famous physicist. Who came up with unbelievable equations that are still being proven decades later. If u have no idea whom he is....then google him. He was using INTELLIGENCE combined with Intuition. He NEVER went to school as boy, so was not spoiled and brainwashed. THIS IS WHAT I MEAN. We should ALL be like him, and we can. If taught from a young age
@Anthony Chen-Kerbowitz also this isn’t a thing someone teaches another. It comes from 1. Meditation 2. Clear distinction between intellect, memory, imagination, intuition. Ability to reach a trance state. This is ALL self accessed from WITHIN. It is called as CHIT means intellect in Sanskrit. Agni means fire. Ramanugan turned his “CHITTAGNI” on Chittagni means “ fire of the intellect” Being able to access information NOT from memory. I think...... From what us called as SOURCE or Akashic Records. ( if I remember correctly) This is all out of the Upanishad And Vedas, etc..... So cool check it out. They had more advanced mathematics, Physics/Metaphysics. Understanding of Energy and many mystical things. Magick is just misunderstood science. The science of manipulating energy within, so it is mirrored in the without. SIMPLE SCIENCE When physics starts to openly study metaphysics....they will start to figure things out. I give them 150 years or so. -1331-
@Anthony Chen-Kerbowitz the system working properly unfortunately disables children. I can see very clearly, by your attitude, you have no desire to actually learn the FACTS!!! Or you didn’t actually read what I wrote. Either way your ignorant to the facts. DEFENDING academia rather than having an open mind. I come up against this time again with my colleagues. Using your mind....but have no idea where or what it is, and don’t care. Using words.... not knowing what they TRULY are. Therefore ABUSING language. I didn’t say you don’t know the definitions. Oh ya, it’s not called a DEFINITIONary. DICTION....Emphasis on pronunciation. PHONETICS. Or SOUND. You don’t know of Resonance? SOUND is the scaffolding of the world. everything physical, is singing an Angelic tune. Do they teach this in school? 😂 When Meditation becomes mandatory in school, then we will be on the right track. Check out the SANSRKITTI school in Tamil Nadu. They do it right, those children are true Human BEings. They KNOW how to BE. I TRULY WISH TO NOT BELITTLE YOU. Simply educate you. As it’s my job as an EDUCATOR. YES, I am a Teacher. Namaskaram my Friend. It is my wish and my blessing that you simply learn the facts. 🙏🙏🙏
@Anthony Chen-Kerbowitz On the contrary my good man. You not only feebly attempt to insult me, but the teachings of all the wisest teachers this Earth has ever known. Ramanajun is still a LEGEND in physics. Every physicist wishes they could bleed mathematics like he did. This is the thing, He Was Not Special or gifted or anything. This is what EVERY human is capable of. He was perfectly normal. Therefore his peers must be abnormal or disabled. But look at what disabled people can do..... so much ***Just Imagine If Everyone could do if they were not disabled*** Being able to memorize and recall IS NOT INTELLIGENCE. Is the memory in a computer the intelligence???? Answer me this one question. It is part of running a computer but just one part. 7 faculties in the Human mind. Intelligence is one. Memory and recall is another. What would happen at work if the faculty got confuses as to what was what?????? The place would not run nearly as smooth as it could Hence.......disabled As in you have not been ABLED to use your intelligence. Drop the ego and consider something new. What, terrified I might be right.
The question on the legal system is more in line with how can you punish people when the universe is predetermined. The only answer I get from anyone is basically just cause.

If the Flash can move at speeds close to the speed of light, several times a day for years, why does time remain relative between him and everyone else? In other words, shouldn't everyone around him start to get older and older each time he runs at close to the speed of light? My theory is he's using wormhole technology.
I hope your comment isn't serious, because I would have to reply that the Flash is a fictional character in a fictional universe with its own convenient laws of physics.
I'd love to see (or hear) a debate / conversation with you and Eric Weinstein. He is a very smart guy but I don't trust people who think they have all the answers. He believes we should not be wasting time with string theory anymore, because it offers no testable proofs. Would be amazing with some great ideas covered.
I find Eric troublesome to take overly seriously for this reason. He has extremely high intelligence at a plethora of advanced, highly dense materials, but he is also deficient in others that are well-hidden from even himself. The vulnerability may have occurred when he became a declarative, public arena intellectual rather than a thinker in greater systemic isolation with only other smart people who would assuredly be better at calling him out on some of his more glaring modeling holes.
That's the (in)famous Measurement Problem. Yes, any theory should be able to give a satisfying account of how the measurement process works in purely physical terms. The reason is that we want our theory to be complete: if reductionism actually holds we want our theory to treat observers like any other system no matter its scale or complexity, OR if reductionism breaks down we want our theory to explain how exactly this happens. All this doesn't necessarily have something to do with the presence of humans.
@@JamesWilson-ve9zi: from the point of view of empirical predictions (including 'post-dictions') yes, they can equally well confront cosmological questions regarding pre-human eras. This is because, being interpretations of quantum mechanics, they are just two ways of formulating the same physics. From a more philosophical perspective, though, Many Worlds seems much more natural than Copenhagen in dealing with cosmology, because MW solves the measurement problem without involving an ad hoc notion of "observer", while Copenhagen postulates "observers" (without actually explaining what they're supposed to be; in a sense it just pretends to solve the measurement problem).
Which one of these (if any)is more likely to be accurate ? 1 if we live in a block time universe, then LaPlace’s demon exists. 2 if LaPlace’s demon exists, then we live in a block time universe. 3 if we don’t live in a block time universe, then LaPlace’s demon does not exist 4 if LaPlaces demon does not exist, then we don’t live in a block time universe.
I love this comment about rising authoritarianism and climate change and I’m posing we look to see if they are connected through science. This is multifactorial, with humans losing ten IQ points over a century. Leaded gasoline, phthalates now in plastics, we are making choices that are impacting our environment, this doesn’t look good. We also see in studies, rising narcissism and cluster B character disorders, is this cultural? Environmental? All of the above? Will humanity swoop and recover to become enlightened In the future as to what causes these events? I sure hope we haven’t poisoned ourselves so cognition has been impaired.
How is the many-worlds theory any different than saying everything that can happen does happen? Is such a sentiment really a useful approach towards gaining better understanding of the universe? I think the weirdness of quantum physics is caused by the creation of mathematical formalism in a universe that has no strict formalism in itself! As Sean says we are all Wishful thinkers who tend to want certain things to be true. It seems like Sean just tends to gravitate towards liking a deterministic model Anyway not sure why positing an incalculable creation of universes every second as reality unfolds is helpful Why not just say we have a probabilistic model because inherently the act of modeling the universe is probabilistic at the most fundamental levels Most of the confusion around quantum physics comes from the fact that in order to measure you have to affect. Meaning you have to actually bounce photons off very small Quantum systems Human intuition is very bad at understanding the relationship between very small, relationships of matter and energy And our language and common cultural conceptions are very clumsy at trying to illuminate these relationships! All the supposed Quantum spookiness like superposition and tunneling is created by a misunderstanding of how the introduction of observational measurement photons effect physics at the most fundamental level Like for example the double slit experiment can easily be explained by the fact that photons have a huge effect at the quantum level So of course we have a radically different experiment when one is completely undisturbed, and the second version has the addition of instruments interfering with the original setup by detecting the happenings with photons. Or an interfering energetic system! Anyway Sean's a really smart guy and I have learned quite a bit from his work. But I definitely see a pattern in his tendency to idealize laplace's demon and the many-worlds interpretation of quantum physics As Sean himself has said just because we can conceive of things doesn't mean that they are necessarily helpful, especially when they are in flagrant violation of everything we know about matter and energy LaPlace is demon is in flagrant violation of everything we know about both classical and quantum mechanics. So not sure why that is a useful construct. And the fact that he keeps returning to talking about laplace's demon and many worlds leads me to believe that maybe that's just a personal bias of his and not an accurate assessment Again really smart guy, really good scientist. Interesting podcast. But from what I can gather the majority of the scientific Community is not on board with many-worlds and I'll put more likelihood in that camp. Until I see more evidence to believe otherwise.
Isn't a strange contradiction to name something "Ask Me Anything", but then say they can't ask you anything. Considering all the lies in today's world, it would be worth changing to simply Q&A, just to create one less lie.
Or Wolfram's, which I think is a bit much. He is much more established within the field and in general and has plenty of summaries of his theory that aren't 800 pages by which to judge it. If correct his theory what he is doing is arguably the most important scientific discovery ever and if not he has gone exquisitely insane in a truly fascinating way, very publicly, worthy of comment either way.

We will suffer immensely if this is not corrected sooner than later.
@Anthony Chen-Kerbowitz
I am trying to make a clear distinction between what’s called as Intelligence and what’s called as Memory storage and recall.
Point is *** WE Have confused the ability to store memory and recall it....IS NOT INTELLIGENCE!!!
There are 7 faculties in the human MIND not brain.
Intelligence is one.
Memory is another.... we have CONFUSED the ability to memorize and recall memory with Intelligence.
This is the great disservice to humanity.
THIS IS IT....
You can ONLY recall memories that you have accumulated with 5 sense organs.
INTELLIGENCE-INTUITION
Allows you to jump from step 1 to the answer.
NOT USING MEMORY
Using INTELLIGENCE.
NOW THAT IS REAL INTELLIGENCE.
MEMORY and the ability to recall ***IS NOT INTELLIGENCE ***
Even though we learned that in school.
Do you get it?
I am not trying to belittle anyone
Or attack.
Simply inform and share THE FACTS
7 faculties in human mind
Intelligence is one
Memory and recall is another.
These are scientific proven facts.
There are many dormant sub groups
But that would get confusing.
@Anthony Chen-Kerbowitz Rananajun....the famous physicist. Who came up with unbelievable equations that are still being proven decades later.
If u have no idea whom he is....then google him.
He was using INTELLIGENCE combined with Intuition.
He NEVER went to school as boy, so was not spoiled and brainwashed.
THIS IS WHAT I MEAN.
We should ALL be like him, and we can.
If taught from a young age
@Anthony Chen-Kerbowitz also this isn’t a thing someone teaches another.
It comes from 1. Meditation
2. Clear distinction between intellect, memory, imagination, intuition. Ability to reach a trance state.
This is ALL self accessed from WITHIN.
It is called as CHIT means intellect in Sanskrit.
Agni means fire.
Ramanugan turned his “CHITTAGNI” on
Chittagni means “ fire of the intellect”
Being able to access information NOT from memory.
I think......
From what us called as SOURCE or Akashic Records. ( if I remember correctly)
This is all out of the Upanishad
And Vedas, etc.....
So cool check it out.
They had more advanced mathematics, Physics/Metaphysics. Understanding of Energy and many mystical things.
Magick is just misunderstood science. The science of manipulating energy within, so it is mirrored in the without.
SIMPLE SCIENCE
When physics starts to openly study metaphysics....they will start to figure things out.
I give them 150 years or so.

@Anthony Chen-Kerbowitz the system working properly unfortunately disables children.
I can see very clearly, by your attitude, you have no desire to actually learn the FACTS!!!
Or you didn’t actually read what I wrote.
Either way your ignorant to the facts. DEFENDING academia rather than having an open mind.
I come up against this time again with my colleagues.
Using your mind....but have no idea where or what it is, and don’t care.
Using words.... not knowing what they TRULY are.
Therefore ABUSING language.
I didn’t say you don’t know the definitions.
Oh ya, it’s not called a DEFINITIONary.
DICTION....Emphasis on pronunciation. PHONETICS.
Or SOUND.
You don’t know of Resonance?
SOUND is the scaffolding of the world.
everything physical, is singing an Angelic tune.
Do they teach this in school?
😂
When Meditation becomes mandatory in school, then we will be on the right track.
Check out the SANSRKITTI school in Tamil Nadu.
They do it right, those children are true Human BEings.
They KNOW how to BE.
I TRULY WISH TO NOT BELITTLE YOU.
Simply educate you.
As it’s my job as an EDUCATOR.
YES, I am a Teacher.
Namaskaram my Friend.
It is my wish and my blessing that you simply learn the facts.
🙏🙏🙏
@Anthony Chen-Kerbowitz
On the contrary my good man.
You not only feebly attempt to insult me, but the teachings of all the wisest teachers this Earth has ever known.
Ramanajun is still a LEGEND in physics.
Every physicist wishes they could bleed mathematics like he did.
This is the thing, He Was Not Special or gifted or anything.
This is what EVERY human is capable of.
He was perfectly normal.
Therefore his peers must be abnormal or disabled.
But look at what disabled people can do..... so much
***Just Imagine If Everyone could do if they were not disabled***
Being able to memorize and recall IS NOT INTELLIGENCE.
Is the memory in a computer the intelligence????
Answer me this one question.
It is part of running a computer but just one part.
7 faculties in the Human mind.
Intelligence is one.
Memory and recall is another.
What would happen at work if the faculty got confuses as to what was what??????
The place would not run nearly as smooth as it could
Hence.......disabled
As in you have not been ABLED to use your intelligence.
Drop the ego and consider something new.
What, terrified I might be right.
The question on the legal system is more in line with how can you punish people when the universe is predetermined. The only answer I get from anyone is basically just cause.
@@michaelsommers2356 I see your argument as a two wrongs make a right. The idea of predeterminism isn't a concept of non change. I hear what your trying to say though.

Is there anything in nature other than quantum physics that is also governed by the Schrödinger equation?
Yes in astrophysics: the rings of Saturn and similar ring-like objects (in an "averaging" approximation in which they're basically a union of massive geometric circles instead of debris made of point-like objects). - gizmodo.com/fundamental-equation-of-quantum-physics-also-describes-1823514535
@@rv706 awesome thanx. I will go thru it later.
If the Flash can move at speeds close to the speed of light, several times a day for years, why does time remain relative between him and everyone else?
In other words, shouldn't everyone around him start to get older and older each time he runs at close to the speed of light?
My theory is he's using wormhole technology.
I hope your comment isn't serious, because I would have to reply that the Flash is a fictional character in a fictional universe with its own convenient laws of physics.
I'd love to see (or hear) a debate / conversation with you and Eric Weinstein. He is a very smart guy but I don't trust people who think they have all the answers. He believes we should not be wasting time with string theory anymore, because it offers no testable proofs. Would be amazing with some great ideas covered.
I find Eric troublesome to take overly seriously for this reason. He has extremely high intelligence at a plethora of advanced, highly dense materials, but he is also deficient in others that are well-hidden from even himself. The vulnerability may have occurred when he became a declarative, public arena intellectual rather than a thinker in greater systemic isolation with only other smart people who would assuredly be better at calling him out on some of his more glaring modeling holes.
Do you think that observation should be included in quantum mechanics as the universe formation does not depend on the human race?
@@nihlify who is observing?
That's the (in)famous Measurement Problem. Yes, any theory should be able to give a satisfying account of how the measurement process works in purely physical terms. The reason is that we want our theory to be complete: if reductionism actually holds we want our theory to treat observers like any other system no matter its scale or complexity, OR if reductionism breaks down we want our theory to explain how exactly this happens. All this doesn't necessarily have something to do with the presence of humans.
@@rv706 if there was no human race would theorys like many worlds and the Copenhagen theory have any value?
@@JamesWilson-ve9zi: from the point of view of empirical predictions (including 'post-dictions') yes, they can equally well confront cosmological questions regarding pre-human eras. This is because, being interpretations of quantum mechanics, they are just two ways of formulating the same physics. From a more philosophical perspective, though, Many Worlds seems much more natural than Copenhagen in dealing with cosmology, because MW solves the measurement problem without involving an ad hoc notion of "observer", while Copenhagen postulates "observers" (without actually explaining what they're supposed to be; in a sense it just pretends to solve the measurement problem).
Which one of these (if any)is more likely to be accurate ?
1 if we live in a block time universe, then LaPlace’s demon exists.
2 if LaPlace’s demon exists, then we live in a block time universe.
3 if we don’t live in a block time universe, then LaPlace’s demon does not exist
4 if LaPlaces demon does not exist, then we don’t live in a block time universe.
At least 15 people didn’t like your answer to their question, haha.
I love this comment about rising authoritarianism and climate change and I’m posing we look to see if they are connected through science. This is multifactorial, with humans losing ten IQ points over a century. Leaded gasoline, phthalates now in plastics, we are making choices that are impacting our environment, this doesn’t look good. We also see in studies, rising narcissism and cluster B character disorders, is this cultural? Environmental? All of the above? Will humanity swoop and recover to become enlightened In the future as to what causes these events? I sure hope we haven’t poisoned ourselves so cognition has been impaired.
Star Trek had "recorders?" Star Trek walkie-talkies? All geek cred lost.
Guacamole.
How is the many-worlds theory any different than saying everything that can happen does happen?
Is such a sentiment really a useful approach towards gaining better understanding of the universe?
I think the weirdness of quantum physics is caused by the creation of mathematical formalism in a universe that has no strict formalism in itself!
As Sean says we are all Wishful thinkers who tend to want certain things to be true.
It seems like Sean just tends to gravitate towards liking a deterministic model
Anyway not sure why positing an incalculable creation of universes every second as reality unfolds is helpful
Why not just say we have a probabilistic model because inherently the act of modeling the universe is probabilistic at the most fundamental levels
Most of the confusion around quantum physics comes from the fact that in order to measure you have to affect. Meaning you have to actually bounce photons off very small Quantum systems
Human intuition is very bad at understanding the relationship between very small, relationships of matter and energy
And our language and common cultural conceptions are very clumsy at trying to illuminate these relationships!
All the supposed Quantum spookiness like superposition and tunneling is created by a misunderstanding of how the introduction of observational measurement photons effect physics at the most fundamental level
Like for example the double slit experiment can easily be explained by the fact that photons have a huge effect at the quantum level
So of course we have a radically different experiment when one is completely undisturbed, and the second version has the addition of instruments interfering with the original setup by detecting the happenings with photons. Or an interfering energetic system!
Anyway Sean's a really smart guy and I have learned quite a bit from his work.
But I definitely see a pattern in his tendency to idealize laplace's demon and the many-worlds interpretation of quantum physics
As Sean himself has said just because we can conceive of things doesn't mean that they are necessarily helpful, especially when they are in flagrant violation of everything we know about matter and energy
LaPlace is demon is in flagrant violation of everything we know about both classical and quantum mechanics. So not sure why that is a useful construct. And the fact that he keeps returning to talking about laplace's demon and many worlds leads me to believe that maybe that's just a personal bias of his and not an accurate assessment
Again really smart guy, really good scientist. Interesting podcast. But from what I can gather the majority of the scientific Community is not on board with many-worlds and I'll put more likelihood in that camp. Until I see more evidence to believe otherwise.
Isn't a strange contradiction to name something "Ask Me Anything", but then say they can't ask you anything. Considering all the lies in today's world, it would be worth changing to simply Q&A, just to create one less lie.
People can ask anything they want, but that doesn't mean he has to answer every question. Nothing about that seems unreasonable to me.
Why do people use the word nothing as if it were something.??
What is nothing??
How can you define nothing?🤔🥴🤨🤔
At around 11:19, I remember this great talk at the RI. Was it really that long ago? th-cam.com/video/_8bhtEgB8Mo/w-d-xo.html
Is string theory at a dead end?
If wave function collapse when we measure it then what about general relativity ?? (matter tells space how to curve)
A permanent lockdown with no travel is the only safe option.
I wish you had more time to answer. Less questions, people! :D
Shouldn't you be working?
danggg sean is not havin any of eric weinstein's shit
Or Wolfram's, which I think is a bit much. He is much more established within the field and in general and has plenty of summaries of his theory that aren't 800 pages by which to judge it. If correct his theory what he is doing is arguably the most important scientific discovery ever and if not he has gone exquisitely insane in a truly fascinating way, very publicly, worthy of comment either way.
