Thanks for another fascinating episode! At first we didn't know where to place your new vids, then we thought they should be categorized as documentaries, but this one really sounds like a radio show or maybe a podcast.
You should do the signed books thing with each interviewee pushing pages here too. Sling a book or two from them to the audience. Better yet, sling a book to the highest ranked comment each week as of the following week's release. That kind of marketing will generate more interesting comments and a general rush of people trying to get in their relevant comments early. Those kinds of metrics will boost the way YT suggests this channel to new viewers. Basically it's an intellectual version of the highly successful GoPro giveaway marketing strategy. Thanks for the upload. I'm curious how John handled Mr. Jurassic Park next week.... 'T-Rex vs Black Hole?' jk but it does sound oddly interesting. As far as people I'd like to hear you interview, Matt from PBS SpaceTime would be really interesting IMO. -Jake
Just obsessed with the channel! Another worth the wait video, thanks so much for all your efforts! (Music wasn’t too loud for me, I’m using my phone & bluetoothing to a speaker if that helps anyone) Keep em coming John!!!✨☄️🌔
Truely. And I tip my hat to you yourself, sir. Being that there are other people out there that can recognise and appreciate that, is a gleam of hope to me for our glorious future...
As noted by Dr. Sutter, I think we're just missing any civilizations out there. I hear a lot of physicists look at the Kardashev scale and say that advanced civilizations would use so much energy that you would see their waste heat. But as an Engineer, especially one that spent a lot of time on power systems, I have to disagree. The more advanced you become, the more likely you are to extract the maximum amount of work out of the heat you have. We've seen that the efficiency of power plants has gone up by about 10% over the past 50 to 60 years. If we, as a pre-Kardashev 1 civilization were able to increase efficiency by that amount in a short amount of time, civilizations at K2 or K3 should be able to extract an extremely high efficiency from their power systems that their waste heat may be close to that of what we seen throughout the Universe for temperatures (around 5K), we'd never be able to spot them looking at their waste heat. I think the big problem is we are making assumptions that just aren't sensical for how to look for alien civilizations.
The thing is, you cannot lower the temperature of your waste heat so close to the universe's background temperature because it then becomes very hard to radiate it away. The universe would radiate almost as much heat back to you as you are trying to radiate away. Also, our galaxy radiates heat at around 10-20 kelvins depending on your location, so a K2 civilization would have to keep the temperature of its waste heat above that, around 50 kelvins to get rid of it with reasonable efficiency. A Dyson swarm at that temperature would be easily detectable with our current instruments.
@@francoislacombe9071 Your ultimate goal with a power system is to eject your waste heat as close to ambient as possible. To state that you would need to eject waste heat at 10 times ambient would be wasting a lot of useful work still contained in that ejected heat. So I disagree that a K2 or K3 would eject that heat that high. What we'd more likely see from an Alien Civilization's Dyson swarms is not their waste heat, but the effect on the light curve of their parent star.
I agree with everything you just said. There's another possible solution I've heard Issac Arthur mention. It's possible we will never need to harness the entire energy of the sun. They might be more interested in getting the minimal amount of energy and live in a virtual world instead of the real world. In theory you could upload your mind to a simulation and live out 10,000 in the simulation while only a few days have gone by in the outside world. This seems even more likely to be applied to machine civilizations, if they exist.
The answer to the question about what's outside of the universe as it's expanding was fascinating to hear. Essentially, using Wittgenstein's philosophy to suggest that we gain an answer by showing the question to be invalid. Asking "What is the meaning to life?" is like asking "What is the colour of the number 3?". However, some individuals actually do experience colour with numbers. With a different perspective, a seemingly nonsensical question has definite meaning. We're often told now that we're not even able to see the entire universe, only the "observable" universe...leaving quite a lot of open space for open conjecture. I think the answer has to be re-phrased as "Given our current knowledge of the universe, the question of what lies beyond has not yet resulted in an understandable perspective." In other words, it's okay to say we don't know.
Easy. Just rile some SJWs and get them to protest the universe for being racist or something. Make an episode about how the same fundamental elements forged in a star are part of what comprise President Trump. That should get enough blue haired hipsters to try and boycott nuclear fusion or the cosmos in general. Then CNN can run a story with a headline something like "Is the universe a white supremacist?" that links to said episode and perhaps AOC could tweet out something about unfair distribution of matter to supermassive black holes and roll out a plan to redistribute H, He, and Li to "underprivileged stellar bodies". Boom. Free PR.
I am not sure where I saw this but a scientist on a show, I think it was world science festival, said something that made me change the way I think about infinity. He said something along the lines of we will never be able to tell if something is infinite or not and infinity is a term we really should not use or ever include. The reasoning went like this, if something is infinite, by it's very nature we can never know that for sure because however far we go with it, if it is math or philosophy, any discipline , there will always be areas that we have not yet explored so we cannot determine it is infinite.
Between you and Isaac Arthur I'm always looking forward to Thursdays. I pretty much agree with Dr. Sutter's opinion. The universe is so stupidly, unfathomably big that, for all we know, there could be a civilization on a neighboring galactic arm and we might never notice. I think it's too early in our development as a civilization to really get the big picture and make conjectures about what we call the Fermi Paradox. So much stuff to discuss and think about. And as always, great interview. I love how this channel is growing. Even if that means my comments will probably get buried really fast now.
FANTASTIC INTERVIEW!! Thanks JMG and Paul Sutter it was a very inspirational and mind expanding discussion, great content. You nailed the background music in the discussion about life in the Universe ( around the 7.00 - 10:00 minute mark) my eyes were just welling up at the insignificant awesomeness of being a human consciousness in this incredible reality. (simulated or not ) :)
Such quality. I'm so freaking glad you started doing these in addition to your other videos. Your other ones are like snacks or appetizers and these are the meaty main course.
You are such an under-rated YT creator John. I love this new channel. Excellent content. Keep it up. Word of mouth will help grow your subscriber base.
@Event Horizon @29:48 "No beginning?" Then the "big bang" (singularity) was not a beginning? Then what was it? @31:42 "Infinite?" Then where and when or at what point did the "big bang" Finite-Beginning (singularity or single point) transition to "Infinite?" How and why did that happen? At what point during "expansion" did the speed limit of light arise?
@27:45 And it's only "on average"--we have yet to fully understand, really have only JUST begun to probe, the "dark" phenomena that we have invoked to "correct" the mismatch between the predictions of preexisting theory and actual observations of phenomena.
Obviously I love the content of your channel(s), but also spending so many hours alone here, tending my critters, have also found company in the warmth of your beautiful voice and manner. Now you have added Eryn's lovely spirited cheekiness. Great! Look forward to Dr. Steve Brusatte next time, from our side of the pond
another fantastic episode featuring another one of my favorite internet scholars. Extremely enjoyable, thanks and keep up the great work Sir /tips hat I also would like to add that I have personally asked Mr Sutter the expansion question and have wrestled with the concept ever since (with some success) but one thing I am sure of is that my cats' meow is mostly ginger. I am also a massive fan of the fact that the universe has an inbuilt 'fog of war', although the implications towards the simulation hypothesis are a little unsettling.
This is my first time to run across this channel, and I was just thrilled when I heard the voice of John Michael Gaudier! John, your voice is pure ASMR to me! All the videos on your other channel are interesting to me so I’m excited to see more on this channel. I’m also excited to learn that you’re an author! I’m gonna have to splurge on myself for a change and buy one of your books soon. Thanks for taking the time to put out these videos that pique my interest!
So glad you put work into producing this longer channel, LOVE it ! Dr Sutter and yourself proved to be a superb discussion on complex subjects that you both enabled us to better understand. Many thanks.
oh ya Paul Sutter,i just watched a show called in Search of with the dude that played Spok in the the star trek movies that hosts it,it’s cool how you get known guests.
Had a HS electronics teacher explaining resistors and got tired of us asking what was in it. He said this was on him and smashed one with a hammer. As we looked at the shattered pieces/dust he said, "Stop asking meaningless questions and just realize that something DOES what it does and move on or you will never get anywhere." This guest reminds me of him. We cannot fix potholes yet we want to understand "everything".
I had a near death experience, and met Death himself. He said to me "I'm a fair reaper, so I will give you one chance and one chance only to escape my wrath and live on. If you can stump me on any request, I will grant you back your life." I thought about it for a minute, and couldn't come up with anything. Then, being nervous and confused, I let out a big fart. Death gave me a befuddled look. So I said "catch it and paint it green".
Like the video but a quote comes to mind “Intellectuals are cynical and cynics never built a cathedral “ I’m not going to put down to pray and end is near , but be practical “ what colour is a cats meow “? Nox nahil
A book about every atom in the universe that's surprisingly short' So basically a book that isn't the size of the universe it's describing? that's some amazing compression right there.
the music is just a bit too loud. but dont take it out completely, i prefer it with background noise. awesome show, you two have great chemistry. i swear the time just flew by. i cant believe the episode is over already! more! more! btw you both would have been AMAZING Art Bell guests.....
Questions like what does the universe expand into… I think better than mathematics to help understand - I think LSD helps you break down your notions of what’s possible.
How do we know we are not in the one of those infinite universes combinations were we are the only life present? Are we assuming that we are the "normal" universe?
SETI was the only shot back in the 60s. I think the radio search is near pointless now that we have other avenues to try and answer this question. To be fair to seti though, much of what they do now is toward those other avenues
I wonder if the universe is some kind of lifeform or consciousness. Can we see past the trees, to see the forrest? there is a limit to what we can percieve
@Brad Watson well, that's one theory anyway. I'd put money on there being no gods as defined by current day religions! And I'm accepting all bets regarding armegeddon too.
I have a question about the expansion of the universe...where these galaxies are going that we 'can't detect' is it possible we just simply can't see that far and the universe isn't 'expanding into the nothingness of itself' simply we can't see that far..
Nice one with well articulated good points. Just my opinion but I think the closer humans come in the search for the answer, the closer they come to asking the right question. I really enjoyed this video, thank you!
It’s wild when Dr. Sutter says, “within the next couple decades” we’ll have the instrumentation to detect biosignatures, and less than a half of a decade later, JWST just might make it happen.
In regards to the "theory of everything" (a quantum model for gravity that allows unification with the strong, weak, and electromagnetic forces): The inverse square law describes all 4 forces, BUT there is still an incompatibility between gravity and the other 3. On the macro level, all 4 forces can be mathematically described with vector fields. Generalized with a spherical shaped or point source, every point in space (extending infinitely) can be depicted as a vector point away from the source radially and having a magnitude inversely proportional to the square of the distance from the source. Take light and gravity for example: On the macro level, the intensity of a light/gravity source drops off with the square of the distance. But the difference is that gravity is an effect of space-time curvature, whereas the light is quantized. So the intensity is decreasing *for 2 different reasons* entirely: The reason light "dims" with distance is because, as distance increases, fewer and fewer photons reach a given point in 3D space. You can think of a spherical shell surrounding the light source. While distance increases linearly, the internal area of that spherical shell increases by the square. Say an observer standing 1 meter away from a light source will recieve 1 million photons. If the observer doubles their distance to 2 meters, only 1/4 of the photons (250K) will hit them. Double the distance again (4 meters) and 1/16 of the photons (62.5K) will hit them. Double the distance once more (8 meters) and 1/64 of the photons (15.6K) will hit them. *But* the energy of each photon remains the same! While the macro-level intensity of a light source can be mathematically described as a vector field, in reality the notion of a vector with a magnitude does not apply to individual photons. But gravity is not quantized as far as we can tell. Vector math describes gravity very well on any scale; macro and micro. Many people have attempted to develop a quantum model of gravity, because they believe it would be elegant if all four forces could be based on quantum mechanics because there is potential for a complete unification theory. They have all failed because the universe is under no obligation to be elegant. Time and time again, gravity has thwarted attempts to be reliably described with quantum mechanics. The best way to describe gravity continues to be an analog substrate that can curve and deform. If gravity was really carried by a quantized particle (i.e. the "gravaton"), there is no way that it could transmit this force through the event horizon of a black hole. Spacial curvature works. All indications are that gravity is not quantized. That should be OK, but some people feel strongly that it should be merely for aesthetic. I personally think that a 2 force universe does have a certain aesthetic... kind of like a Ying/Yang type thing. You have one "force" (gravity) that governs space itself. And one "force" (strong-electro-weak) that governs all the "stuff" INSIDE space (like matter/energy).
Yes, you think the gravity vector can be free of planck distances, but as you state there are people (like me) who don't think so. Though this "pixelation" couldn't be the reason why gravity is so weak, it should have same effect in electromagnetics and light too. (Sorry leaving the topic:)
if the universe is infinite, and the ways to arrange matter is finite, then there are infinite versions of the universe where I do meet my doppelganger I read Jorge Borges labyrinths in university. Every once in a while I have a moment of clarity about how much that book truly reflects the vary questions asked in this video
They can't. I don't where they get this 13 billion year number, a year is the time it takes one planet and that planet is earth to orbit the sun. Well a year on Maris is twice that. So how they come up with these numbers I don't know. An atomic clock knows what a second is, how many seconds and in a hour, after then I think it breaks down as days are different on a planets and there is no day in space.
Omg I only knew Johns other channel and I found this one a few days ago.....I watched every video. It is soooo amazing to hear such great minds on one Channel. Iam from Germany and science here is a bit ,,boring“ for the most people, so I flee to Englisch Channels. I love the channels of JMG, Isaac, Scott, the Action lab guy and and and. I love how modest the big minds here are, it’s so beautiful. Keep it up 🤙
I like this guy, he's one of only a handful of experts who can just say we just don't know enough to even guess. All we can do is state a theory and then try to prove it wrong.
A Kelvin-Helmholtz wave (or instability) occurs when there's an interface with (high) velocity difference. Think Jupiter's hot spot. For other who wondered (at 20:00)
"...Understanding our big messy existence." Way better than Brian Greens's "The Elegant Universe" [I love Brian Greene, it's just the universe is messy, not elegant!]
Iuno, it seems elegant to me. It’s consciousness that lacks elegance. The universe acts without thought, and knows exactly the parameters of it’s existence. We sit here and try to figure it out via guess and check. Maybe the elegance is the first principle unit, layered on top of itself tons of times until it looks messy. or maybe elegance arises from infinite layers if messiness, by your definition.
Good show John! Very interesting as always. Also super random to see my hometown Stockholm (17:25) in between videos of telescopes and astronomical phenomenon.
Awesome, new channel to binge! Also, great discussion, I was hooked through out, couldn't even play video games while listening like I do most other podcasts that don't involve Science.
Too right. Light speed being inviolable is an assumption, bending space and quantum teleportation have yet to be disproven as theories. So I'm not sure why this guest is saying "we'll never know" because someday we might. Also saying there is no exterior to the universe seems baseless.
@@Zerbii Fair points but until you come up with better theories, our current physical laws are just that - laws. Until you can find a way to go faster than light or create energy from nothing or violate causality or whatever, then yes there are questions that don't make sense. Do you enjoy being an elephant? See that is a question that doesn't make sense, even though it has a yes or no "answer".
"The universe doesn't care about you." True, but the universe gives itself entirely as a foundation for the most complex phenomenon we've witnessed, our self-awareness, to causally arise. "You're not special." True, but also untrue. Each iota of consciousness is unique, the result of a trillion trillion trillion subatomic and supra-atomic reactions and events, arising at iota of consciousness that observes all creation from an entirely unique and 'never-to-be-copied' point of view. So you are special. In the most unbelievably deep, profound, 'single note in the cosmic symphony' sense of the word. I fear the good Doctor is one of those individuals who looks only at dynamics, numbers, physics, and fails to see the staggering implication of those things in what self-aware life really is.
The universe doesn't care, but it doesn't not care either. At the very least it "cared" enough to produce you to experience a chunk of it. This is probably one of those poorly formulated statements people impress their own attitude on more that anything.
We spoke with Event Horizon Telescope team member Dr. Feryal Ozel about the First Image of a Black Hole: ruclips.net/video/MJAGWnyFG4I/видео.html

cat’s* meow is fog-colored in temperatures which condensed the moisture.
@St0rm Ranger In other words, a cat's meow doesn't have a color.
Awesome video as always! Love the work from both you and Dr. Paul Sutter!
Such a great discussion . Should be 100 times the viewer's.
Like the video but a quote comes to mind “Intellectuals are cynical and cynics never built a cathedral “ I’m not going to put down to pray and end is near , but be practical “ what colour is a cats meow “? Nox nahil
This is the best space/science channel.
A book about every atom in the universe that's surprisingly short'
So basically a book that isn't the size of the universe it's describing? that's some amazing compression right there.
All the episodes of event horizon are excellent but this one is truly a standout. Can't believe I missed this.
Excellent discussion. Thank You for posting this. Absolutely love these type of talks. Great job.
Check time stamp 27:23- Synesthetes can see the color of a cat's meow. Paul may may want to rephrase or change the analogy.
the music is just a bit too loud. but dont take it out completely, i prefer it with background noise. awesome show, you two have great chemistry. i swear the time just flew by. i cant believe the episode is over already! more! more!
btw you both would have been AMAZING Art Bell guests.....
Read the title and had a nerdgasm. Instaclick!
Just found your channel. Must say, im loving it. I have been binge watching for the last few hours. Great content, keep up the good work
Questions like what does the universe expand into… I think better than mathematics to help understand - I think LSD helps you break down your notions of what’s possible.
How do we know we are not in the one of those infinite universes combinations were we are the only life present?
Are we assuming that we are the "normal" universe?
i really like the new channel ! keep up he good work John
SETI was the only shot back in the 60s. I think the radio search is near pointless now that we have other avenues to try and answer this question. To be fair to seti though, much of what they do now is toward those other avenues
@Shrek - Quantum entanglement doesn't transmit information/cannot be used to transmit, PBS spacetime at youtube has great explanation about this.
I wonder if the universe is some kind of lifeform or consciousness.
Can we see past the trees, to see the forrest?
there is a limit to what we can percieve
@Brad Watson well, that's one theory anyway.
I'd put money on there being no gods as defined by current day religions!
And I'm accepting all bets regarding armegeddon too.
I have a question about the expansion of the universe...where these galaxies are going that we 'can't detect' is it possible we just simply can't see that far and the universe isn't 'expanding into the nothingness of itself' simply we can't see that far..
This was an especially fun listen, thanks much
Thanks for watching!
This one is my favourite video on this channel to date.
Another great production.
This is the single, most powerful RUclips video I’ve seen 10.06.20.
Short version: 31:02 Is the "entire universe infinite? Maybe, maybe not."
Loving the topics and guests, keep up the good work JMG!
Nice one with well articulated good points. Just my opinion but I think the closer humans come in the search for the answer, the closer they come to asking the right question.
I really enjoyed this video, thank you!
It’s wild when Dr. Sutter says, “within the next couple decades” we’ll have the instrumentation to detect biosignatures, and less than a half of a decade later, JWST just might make it happen.
Music from start to finish is great, but in the first half of the video, the music is about 40% too loud. Please lower the volume. Thanks.
Name of music in the background? I would love to have it. Thanks.
There's a fair bit listed at the bottom of the description but it wouldn't surprise me if you're talking about the Stellardrone parts.
In regards to the "theory of everything" (a quantum model for gravity that allows unification with the strong, weak, and electromagnetic forces): The inverse square law describes all 4 forces, BUT there is still an incompatibility between gravity and the other 3. On the macro level, all 4 forces can be mathematically described with vector fields. Generalized with a spherical shaped or point source, every point in space (extending infinitely) can be depicted as a vector point away from the source radially and having a magnitude inversely proportional to the square of the distance from the source. Take light and gravity for example: On the macro level, the intensity of a light/gravity source drops off with the square of the distance. But the difference is that gravity is an effect of space-time curvature, whereas the light is quantized. So the intensity is decreasing *for 2 different reasons* entirely:
The reason light "dims" with distance is because, as distance increases, fewer and fewer photons reach a given point in 3D space. You can think of a spherical shell surrounding the light source. While distance increases linearly, the internal area of that spherical shell increases by the square. Say an observer standing 1 meter away from a light source will recieve 1 million photons. If the observer doubles their distance to 2 meters, only 1/4 of the photons (250K) will hit them. Double the distance again (4 meters) and 1/16 of the photons (62.5K) will hit them. Double the distance once more (8 meters) and 1/64 of the photons (15.6K) will hit them. *But* the energy of each photon remains the same! While the macro-level intensity of a light source can be mathematically described as a vector field, in reality the notion of a vector with a magnitude does not apply to individual photons.
But gravity is not quantized as far as we can tell. Vector math describes gravity very well on any scale; macro and micro. Many people have attempted to develop a quantum model of gravity, because they believe it would be elegant if all four forces could be based on quantum mechanics because there is potential for a complete unification theory. They have all failed because the universe is under no obligation to be elegant. Time and time again, gravity has thwarted attempts to be reliably described with quantum mechanics. The best way to describe gravity continues to be an analog substrate that can curve and deform. If gravity was really carried by a quantized particle (i.e. the "gravaton"), there is no way that it could transmit this force through the event horizon of a black hole. Spacial curvature works.
All indications are that gravity is not quantized. That should be OK, but some people feel strongly that it should be merely for aesthetic. I personally think that a 2 force universe does have a certain aesthetic... kind of like a Ying/Yang type thing. You have one "force" (gravity) that governs space itself. And one "force" (strong-electro-weak) that governs all the "stuff" INSIDE space (like matter/energy).
Yes, you think the gravity vector can be free of planck distances, but as you state there are people (like me) who don't think so.
Though this "pixelation" couldn't be the reason why gravity is so weak, it should have same effect in electromagnetics and light too. (Sorry leaving the topic:)
Said it before,but I will say it again best media channel on any platform......
if the universe is infinite, and the ways to arrange matter is finite, then there are infinite versions of the universe where I do meet my doppelganger
I read Jorge Borges labyrinths in university. Every once in a while I have a moment of clarity about how much that book truly reflects the vary questions asked in this video
Crushnaut - if the universe *is* infinite don't worry, you have an infinite number of doppelgänger out there to meet :-)
How can anybody quantify the age of the universe?

@@100percentSNAFU So says the hitchhiker :)~
Measure the distance between galaxies. Then measure how fast they are moving away.
Now run that backwards.
They can't. I don't where they get this 13 billion year number, a year is the time it takes one planet and that planet is earth to orbit the sun. Well a year on Maris is twice that. So how they come up with these numbers I don't know. An atomic clock knows what a second is, how many seconds and in a hour, after then I think it breaks down as days are different on a planets and there is no day in space.
Read a little. You'll learn how.
Omg I only knew Johns other channel and I found this one a few days ago.....I watched every video. It is soooo amazing to hear such great minds on one Channel. Iam from Germany and science here is a bit ,,boring“ for the most people, so I flee to Englisch Channels.
I love the channels of JMG, Isaac, Scott, the Action lab guy and and and.
I love how modest the big minds here are, it’s so beautiful.
Keep it up 🤙
great video. thanks I will only have to watch again 5 times to understand!!
This is the kind of video I’ve been looking for for awhile now.
I like this guy, he's one of only a handful of experts who can just say we just don't know enough to even guess. All we can do is state a theory and then try to prove it wrong.
I really really love this channel!
Music is too loud, it's distracting. Perhaps dial it back a bit???
Same problem in some previous videos. Hope he fix that in the future.
I thought the volume was fine
I listened with headphones and didn't find it intrusive.
I had to turn it off after a while. Can you do a version without the music?
Fine with headphones for me
The very best explanation of the subject of an infinite universe on RUclips to date.
MIND FULLY BLOWN.
THANKS SO MUCH.
Terrific, very interesting interview. Thanks.
A Kelvin-Helmholtz wave (or instability) occurs when there's an interface with (high) velocity difference. Think Jupiter's hot spot.
For other who wondered (at 20:00)
I would love this channel in Podcast form.
Zesty Crab Legs Yes, or I need to pay for youtube red so I can play this without getting in trouble while driving to and from work.
You can also install arktube. Can't remember if you need root, but then no need for RUclips Red.
if it helps, you can listen to youtube audio only with screen off if you use firefox. just select "request desktop site"
It does not.
@Steven Schweinberg Not saying instead of. In addition to.
wow, best description of the Higgs mechanism I've ever heard. Kudos!!!
"...Understanding our big messy existence." Way better than Brian Greens's "The Elegant Universe" [I love Brian Greene, it's just the universe is messy, not elegant!]
Iuno, it seems elegant to me. It’s consciousness that lacks elegance. The universe acts without thought, and knows exactly the parameters of it’s existence. We sit here and try to figure it out via guess and check.
Maybe the elegance is the first principle unit, layered on top of itself tons of times until it looks messy.
or maybe elegance arises from infinite layers if messiness, by your definition.
Good show John! Very interesting as always. Also super random to see my hometown Stockholm (17:25) in between videos of telescopes and astronomical phenomenon.
31:00 What is the 10^26 based on?
Awesome conversation as always. Love this content. But, music a bit too loud.
Awesome, new channel to binge!
Also, great discussion, I was hooked through out, couldn't even play video games while listening like I do most other podcasts that don't involve Science.
There are no meaningless questions Paul, what's possible changes over time.
Exactly.
Too right. Light speed being inviolable is an assumption, bending space and quantum teleportation have yet to be disproven as theories. So I'm not sure why this guest is saying "we'll never know" because someday we might.
Also saying there is no exterior to the universe seems baseless.
@@Zerbii Fair points but until you come up with better theories, our current physical laws are just that - laws. Until you can find a way to go faster than light or create energy from nothing or violate causality or whatever, then yes there are questions that don't make sense. Do you enjoy being an elephant? See that is a question that doesn't make sense, even though it has a yes or no "answer".
LOVE YOU TWO!! Great collab ♥
I like videos like these! So adventurous.
Is this a Swedish channel?
I noticed a couple of clips from Stockholm around 17:40.
Getting better and better
Loving this one! It's such an interesting thing to think about the universe on macro and microscopic scales.
Any update on when your book will be available on Audible?
What's the source for the thumbnail image?
"The universe doesn't care about you."
True, but the universe gives itself entirely as a foundation for the most complex phenomenon we've witnessed, our self-awareness, to causally arise.
"You're not special."
True, but also untrue. Each iota of consciousness is unique, the result of a trillion trillion trillion subatomic and supra-atomic reactions and events, arising at iota of consciousness that observes all creation from an entirely unique and 'never-to-be-copied' point of view. So you are special. In the most unbelievably deep, profound, 'single note in the cosmic symphony' sense of the word. I fear the good Doctor is one of those individuals who looks only at dynamics, numbers, physics, and fails to see the staggering implication of those things in what self-aware life really is.
We don't know enough to give a definitve answer to this subject. Life can be a rare thing or a constant. We simply don't know.
malcom young it’s gotta be both
The universe doesn't care, but it doesn't not care either. At the very least it "cared" enough to produce you to experience a chunk of it.
This is probably one of those poorly formulated statements people impress their own attitude on more that anything.
All you have to do is believe in God(s). Not that difficult. Why are you science hippies allergic to the most obvious?
@@CandidDate cause what made God mate
26:45 The universe is expanding into some vague sense of ennui .... That's it!! that explains so much of life and existence. Thank you!!!
Love your content and rich presentation.
Thank you!
I’m enjoying these longer episodes
