For any of you who haven’t read any of prof Greene’s books you are missing out guys. “The elegant universe” and “the fabric of the cosmos” are my favourites. Very deep yet not too hard to conceptualise. Try the audiobook versions if you enjoy listening to prof Greene’s calming yet attention demanding demeanour. Fabulous books.
One of the sweetest gentlemen on the planet- Neil and Chuck. The enthusiasm that Neil brings alongwith tonnes of astro-knowledge and the attentiveness that Chuck throws in- if there was a perfect world, these two would be the ideal teacher-student combo. Love them ❤
I’m a pharmacist with a bachelor of commerce degree in financial accounting and next year I’m going to be registering and studying Electrical Engineering because Dr Neil got me back into living Physics again and I had always wanted to be an engineer.
That painting in the background of Brian Greene is absolutely EXQUISITE!. to me it speak an unreachable unknown light in the darkness that takes in every ounce of energy, the light attacking and feeding said darkness until there is no room for for it to fill, a black hole. Absolutely exquisite!
Brian Greene is one of my favourite science communicators. He just has this ability to explain complex concepts in a way almost anybody can understand.
No. He interrupts, & doesn’t add anything useful to the discussion. It’s disrespectful to Professor Green having someone of chucks caliber on the show.
@@macysondheimand also i noticed you in a lot of comments lol. Stop going on a hate comment spree bro. Its not healthy. I understand you dont like his presence but come on dude,you are better than this. You have better things to do in your life. Going on a hate comment spree? Seriously?
@@macysondheim I agree, I can do without the atrocious Dad Jokes if there's more science. This show doesn't need a so-called comedian to make it "accessible". {:o:O:}
My two favorite physicists... I love listening to Brian every night before bed. Always a mind blowing conversation between you too. I would love to be in Chuck's position just once.
After 40 years of being on this planet I was so excited to finally understand this that I texted my Mom and told her about the atomic clock experiment. Her response was "Aww that's nice honey".
Without Einstein's input, many years ago I realized that 5 minutes of time when I was at work was way slower compared to the 5 minutes immediately after I pressed the snooze button.
when the atomic clock was strapped on the pam am plane... does the movement of wires affect the distance an electric pulse has to travel that measure's time? so if the wire is moving at 600mph, that electric pulse will be in that wire a billienth of a second longer than it would relative to the surface of earth... if that pulse is what measures elapsed time, wouldn't the measurement taken then be challengeable?
in the movie contact (based on a book by Carl Sagan)... when the pod is dropped and takes Ellie away at the speed of light, why did only a millisecond pass on earth? for the 90 minutes she was gone, shouldn't about 12 years have passed on earth? not just a millisecond?
Chuck I’m impressed really.. I can’t believe you are a comedian .. if I didn’t know you , I would think this is a discussion between 3 time travel experts .. it’s incredible
One of the best star talks. Brian was terrific, Chuck killed it for everybody there with his wit, humor and serious scientific curiosity. and Neil is just Neil who by the way is getting better with age.. Love it.
Chuck is very smart, he knows most of these answers already. But he plays it up for the camera and asks questions in a easy to understand and comic way. He and Neil are awesome
This was an absolutely great episode, and I’m not even done with it yet. Brian has a fantastic way to speak in a manner that I can understand it. Yes, I need to rewind…a few times..but I can actually understand it. I’ve never related to Chuck more 😂
There can definitely be a canyon of suffering in translation when it comes to these topics and it takes a person as schooled and deft in the English language as in their own chosen field to break down and convey what they’re trying to say in a way a lay person can understand LOL
Thank you for a delightful episode, love listening to Dr Greene, his explanation is always clear and on point. Would love to watch Brian Time edition of the show as well ;)
Yeah. Thats my thoughts too... Do we actually have free will? Is free will just a individual false perception? I hope there will be a another video about this topic too
Why is it that we spend our lifetime to try to attract the universe when it’s doesn’t or is it the other way around … so far what I see is that the universe have not cover or title… it’s purpose is not to the attract ? I am so sure beyond that is the heart
Loved the episode. I always love in movies the concept of time travel, for whatever it feeds my soul, just as this episode did. Thank you for the experience.
Im a year late, but i love watching Chucks understanding of the universe just broaden so much as this goes on. I love his enthusiasm to learn about this
Chuck really makes Neil laugh. I find myself laughing at Neil's laughing. I like that even though Chuck is there for the humor, he's smart enough to join the conversation.
Love all your videos Dr. Tyson! You are so brilliant and you explain space and Earthly phenomenon in such a way that average folks can understand. I love all the accents and humor that Lord Nice adds to the show! 5 stars! ⭐⭐⭐⭐⭐
The general answer to the question about what a time traveler to the past would look like if you could observe his world line,and information, is simple. You would see him moving backwards, as you move forward in time you would be seeing him at an earlier and earlier moment in time for his timeline. The main difference is the dimension that is space for us, is time for them, and vise versa. There is no violation of entropy because his forward timeline into to the past will still have that same matter/energy come back to the future, so there is no violation. Another important point, as Dr Frank Tipler pointed out in his paper, is that a time machine takes an incredible amount of energy. The amount of mass in a humane body is huge E = you know what etc, but there is not violation of thermodynamics. In other words if there are now two of you in the past, that energy had to come from someplace. His time machine was a rotating singularity, the math trick was that the singularity has an infinite length so it does not turn into a black hole. Though Dr Thorne's discovery is quite elegant and original. The ways of traveling to the past that Einstein and Godel spoke of were kind of different methods. Faster than light particles need different reference frames, and with gravity you can warp the spacetime for a shortcut, like with cosmic strings, and with black holes you simply tip the light cones over so the null vectors approach 0, which is a nice way of saying you are on the edge of space and time, and when you're past the null curve then you can move back in time simply by moving through space. In Physics these are known as closed time like lines, or Closed Timelike Curves, to be more accurate. The wormhole solution is easiest to visualize if you think about yourself holding a clock in the mouth that is moving, and holding a clock in the mouth that is not accelerating. The length of a wormhole cane be close to 0, which makes it easier to understand. To really understand the fundamental nature of time travel you must understand the Special Theory of Relativity and the Relativity of Simultaneous events, that is the key to all the interesting time travel. Hawking's conjecture is mostly based on the fact that different relative reference frames will see the energy diverge, and some will see it converge, but which is correct? There is an interesting new paper out from China on this subject.
Chuck is so hilarious, Bravo man! I love time travel discussion! Branching timelines (multiverse) at the moment you travel back in time would seem more plausible. Don't ever leave this timeline or your future will never be as you remember it. Good luck ever getting back to your original future either. We need a temporal mechanics course.
I like Star Talk very much, the characters, the kookie banter, warmth and commradery{sp}, the topics and incites. Its a science show...with and about people 😁 I want to say how much I enjoy what you guys put together and present. If I were to suggest a topic area it would be coverage of specific space travel settlements. where are we apt to settle/explore first and aside from money what are the biggest obstacles? What big science areas and questions could drive this kind of effort. The whole "back to" and beyond the moon.
It would be good if Neil and Chuck would let the guest finish his sentences and explanations first before cutting /interrupting Brian Greene explanations in mid sentences. It has happened so many times in the Startalk videos where Neil and Chuck would interrupt the guest explanations in mid sentences. Thank you.
I agree: on random comments and most of Chuck, though if you read other comments, Chuck actually adds entertainment, humor, and a common man value in these talks. But when u have a deeper understanding of the topics at hand, as Neil does, u have questions, lots of them, and if u wait till the end, you'd miss what inspired the question, even if you wrote down your question to ask later, as we're conditioned to think as the "polite" thing to do. Yet in this (and many other cases), interrupting to ask questions is part of the beauty, excitement, and imagination of science...
You ain't seen nothing yet! NDT's every appearance on Joe Rogan is a dialogue between NDT and his own enormous ego, while totally excluding Rogan from the conversation
It’s a little bit too much at times.. I’d watch Dave Chappelle or Bill Burr if I wanted laughs or comedy.. it’s entertaining but gets annoying at times..
I tried to listen My concentration was interrupted by Laughing . I would try to refocus but it was very difficult due to laughter about some invisible thought that I could not grasp. Please do this one over without all of the eruption’s from laughter and silly talk I really am interested. I will not give it negative. Due to the topic.
I don't know if it's the actual first mention of literary time travel, but Jormangander travels backward in time when fighting Thor at Ragnarok in Norse mythology, which predates Charles Dickens by about a thousand plus years lol.
In the Guy Piece remake of _The Time Machine,_ there's an extra bonus feature on the DVD, in which the filmmakers point out that after showing the fiance's various unpreventable death/s several times, they stopped, as it got to the point that they was thinking one would start getting into cartoon territory, like dropping on her an anvil or piano from second floor window...
Neil , the quality and wide diversity of your guest's over the last 6 months or so , have really put me back into your orbit, so to speak, and also love Chucks input into the mix as well. Thanx'
Why? Wouldn't it just cloud your mind? Anyone I've been around (my entire family) seems to think they are saying and hearing mind blowing things, but it seems to just open them up the experiencing epiphanies through nonsense
Why I like this before I like it. I didnt push the like botón. Is this bikini bottom or W is a me mies no se dice mixe o ya. I love the B of your ideas. You whitey wait it guey. Blackys is bet er Black Kiss no. Never Just Kiss Block that Black. And Black list the wise man. That isnt something. You re sure right. May be anything as everrynhing sure. I luppi that style from a blamaste.
You guys are so funny. More so than any tv show I watch or movies, I consistently find myself laughing more watching StarTalk than anything else! Love it
I never thought _A Christmas Carol_ involved time travel; even the Ghosts clarify he's seeing Visions of what has transpired, is transpiring, will transpire [technically _may,_ as the future would be a choice; he was being shown *_a_* (possible) future that would happen if it had not been shown to him]...
I mean, it's possible they plucked the memories out of his head and showed them to him, since we're talking magic (ghosts). But the scientific explanation for seeing the past is photons from the past traveling forward to your retinas in the present (or, as they conjectured, you in a wormhole looking out at the photons from the past as they were emitted to see what was happening X number of years ago).
👽Great discussion as always Neil. Dr. Strange has a 'Stargate' creating ability of sorts not mentioned in the video. Knowing where to 'rip' spacetime for a desired location seems impossible. Another interesting topic from the movie interstellar not mentioned is the 'singularity' being inside the 4th dimension tesseract. I would love to hear your thoughts on this subject. Lastly, your thoughts on a possible scenario that we are not the first technological civilization that has inhabited Earth. For example, what if 100 million years ago a civilization left Earth knowing an asteroid was coming? The one that took out the dinosaurs. Cheers Blessings. 🙏
Mr. Sommelier may have actually sent Lord Nice Wine🍷 🥂 had he known he was communicating with a actual American Lord. Outstanding episode as anticipated #LordNice #Dr.BrianGreene #Dr.Tyson #TimeTravel #UntilTheEndOfTime #RespectLordNiceTitle (Shout out to Dr. Rick Marshall and Dr. Holly Cantrell "The Land Before Time") .Tachyons ROCK
This is the only thing that keeps me up. The explanation alludes me but I think I just got closer. Thank you. Time as a linear straight line is the problem . Time is not what we think it is at all, it's this movable feast
I really wanna thank you Neil and Chuck for all these videos and explainers, I think they're as informative as entertaining, and for me one of the most interesting content to find on UA-cam. Send support from Mexico🇲🇽
For all the flaws within that movie, The Matrix: Revolutions put it perfectly: "you didn't come here to make a choice you already made it. you're here to try to understand why you made it". "Destiny" is just semantics. A person, under the exact same circumstances, will always choose the same path, hence "Destiny". I'm not even a scientist and It's obvious to me. The "destiny" of my 10 year old me will always be me.
Yeah i think it represent really well that idea that you could travel to the past (and that you always do that) and fullfilled the causal chain of events
I love you guys. Nevermind the wisdom and knowledge you bring with every episode and every guest, but the sheer joy you give us is really something else. i love physics, mostly due to reading your books. but i somehow ended up as an MD.haha seeing your content always reminds me why i loved this field, and why i always will. You guys always bring order to my entropy. Cant wait to read Brian's new book during my down time in the clinic. Cheers!
Time travel does exist. Eg. You can send a message to yourself (or to someone else) at 2:58 AM on the day that the clock will be put back from 3 to 2 o'clock. You send the message at 2:58, and two minutes later, when it's 2:00 AM you see that you sent a message at 2:58... Another example. If you take a plane from Japan to San Francisco, you can leave on the 7th of January at 1:00 AM and you arrive 10 hours later in San Francisco at 6:00 PM on the 6th of January.
"How to Live Safely in a Science Fictional Universe", written by Charles Yu, is a favorite book of mine based on time travel. Really gives your mind a workout on understanding causal events.
So far so good... 3 of my favourite guys in Science...Neil and Chuck Nice...the Chuck D and Flava Flav of PHYSICS. Brian Greene .... the Joel Olsteen of String Theory...I LOVE this movement!!!
love this podcast. it's fun, it's educational, it's inspirational, it's like a mixture of what I prefer to watch as a content in one package. it's just DOPE!
I love listening to smart people. I always come away just a little smarter, myself, thanks to these wonderful people who are willing to share their knowledge. Thank you, everyone. And remember, you can buy their books USED for a fraction of the list price, or even get your library to order a copy if you can't afford to buy them. While in school, I would spend lots of time at the library, reading things that I couldn't afford to buy.
I live in the City of Portsmouth in England, where Charles lived before writing is books. A Christmas Carol always struck me as a brilliant example of time travel.
For the record, in films and television with decent production budgets, we're now doing digital scans of actor's faces/body parts in order to create lifecasts to sculpt customized prosthetics on. No need for panic attacks or to be sedated anymore :)
42:25 this got me thinking, if you can use the black hole and hawking radiaton as a teleporter, you throw stuff inside one teleporter, shoot out the particles through space and gather them at another teleporter at different location and then read the information of the object it once was, and then reconstruct it
There were several publications between the release of "A Christmas Carol" (1843) and "The Time Machine" (1895) that explored themes of time travel: 1. "The World As It Will Be" by Émile Souvestre (1846) - This story involves a journey to the year 3000 using a flying locomotive 2. "The Clock That Went Backward" by Edward Page Mitchell (1881) - This story features a clock that transports characters back to the 16th century 3. "El Anacronópete" by Enrique Gaspar y Rimbau (1887) - This novel includes a machine that allows characters to travel back to various historical periods 4. "Looking Backward: 2000-1887" by Edward Bellamy (1888) - This novel involves a character who wakes up in the year 2000 after a long sleep 5. "A Connecticut Yankee in King Arthur's Court" by Mark Twain (1889) - This story features an American who travels back to the time of King Arthur
For any of you who haven’t read any of prof Greene’s books you are missing out guys.
“The elegant universe” and “the fabric of the cosmos” are my favourites.

One of the sweetest gentlemen on the planet- Neil and Chuck. The enthusiasm that Neil brings alongwith tonnes of astro-knowledge and the attentiveness that Chuck throws in- if there was a perfect world, these two would be the ideal teacher-student combo. Love them ❤
I’m a pharmacist with a bachelor of commerce degree in financial accounting and next year I’m going to be registering and studying Electrical Engineering because Dr Neil got me back into living Physics again and I had always wanted to be an engineer.
How’s that going? That sounds awesome
That painting in the background of Brian Greene is absolutely EXQUISITE!. to me it speak an unreachable unknown light in the darkness that takes in every ounce of energy, the light attacking and feeding said darkness until there is no room for for it to fill, a black hole. Absolutely exquisite!
Brian Greene is one of my favourite science communicators. He just has this ability to explain complex concepts in a way almost anybody can understand.
He's not just a science communicator. He's a leading theoretical physicist, a brilliant scientist, unlike NDT
First saw him on JRE and the way he articulated his thoughts fascinated me. As well as his theory. Always liked him since then
There's a 10+ hour video of him on here teaching physics stuffs. For those interested. It's advanced.

You are in his position rn listening at home like him. but chuck just interrupts every episode and guest.
One of the best episodes! Brian Greene is the man! 🔥🔥
Brian Green and Neil what a combination, I have been watching both for so long and glad they are in the world. Real science, real people refreshing.
We need Brian every 3rd episode ❤️😁 the guy is so great!
My 3 favorite people!! I got so excited when I saw this video pop up. You made my day!
wow, so sorry you don't have real friends who should have been your "favorite people". that's weird.
This is a fantastic discussion. Thanks guys
Adding my vote for Chuck Nice as co-host on all episodes! He’s needed!
Then you can count on my vote to boot Chuck off the show.

I have never laughed so much, nor learned so much, in a StarTalk episode. Bring back Brian Greene often! 🎯♥
One of the best episode on star talk
Neil and chuck are so synchronized and Brian Green is just a amazing scientist
no cap
when the atomic clock was strapped on the pam am plane...
does the movement of wires affect the distance an electric pulse has to travel that measure's time?
so if the wire is moving at 600mph, that electric pulse will be in that wire a billienth of a second longer than it would relative to the surface of earth...
if that pulse is what measures elapsed time, wouldn't the measurement taken then be challengeable?
in the movie contact (based on a book by Carl Sagan)...
when the pod is dropped and takes Ellie away at the speed of light, why did only a millisecond pass on earth?
for the 90 minutes she was gone, shouldn't about 12 years have passed on earth? not just a millisecond?
Always more than one solution to these styles of equations
Oh man !!
I've been waiting for a long time to see Brian , Neil and Chuck together.
It's like a party for nerds .
"Stop being so damn interesting" is the best compliment you'll ever get from someone like Neil.
Forrrr real
It’s charming how they get along with each other and smile and laugh together. Makes me feel better about the world lol
Minute 43:19 question. It's lovely I had that question for a while. Thanks
Chuck I’m impressed really.. I can’t believe you are a comedian .. if I didn’t know you , I would think this is a discussion between 3 time travel experts .. it’s incredible

Its true tou become the company you keep. Hang around scientists a lot you'll start sounding like one
love greene he's such an enthusiastic and interesting educator
Hahha. Filthy with Physicist.hahaha🤣🤣🤣
Chuck still asked the biggest question here, one about the cells. Amazing.
Love the chemistry between these 3. Always a delight! Science, humor and comradery

Chuck is very smart, he knows most of these answers already. But he plays it up for the camera and asks questions in a easy to understand and comic way. He and Neil are awesome
I felt like Neil was dialing down his insight with Dr. Greene, or maybe he was just hungover or something. Regardless, it worked; great episode.

The general answer to the question about what a time traveler to the past would look like if you could observe his world line,and information, is simple.

I don't know if it's the actual first mention of literary time travel, but Jormangander travels backward in time when fighting Thor at Ragnarok in Norse mythology, which predates Charles Dickens by about a thousand plus years lol.
Bro played God of War and is on a mission
In the Guy Piece remake of _The Time Machine,_ there's an extra bonus feature on the DVD, in which the filmmakers point out that after showing the fiance's various unpreventable death/s several times, they stopped, as it got to the point that they was thinking one would start getting into cartoon territory, like dropping on her an anvil or piano from second floor window...
I LOVE Brian Greene's incredible work, and also his intriguing personality traits. These three ( 3 ) are amazing together.
Neil , the quality and wide diversity of your guest's over the last 6 months or so , have really put me back into your orbit, so to speak, and also love Chucks input into the mix as well.
Thanx'
Who else gets high and watch Star Talk?
I literally just toked a whole blunt
Why? Wouldn't it just cloud your mind? Anyone I've been around (my entire family) seems to think they are saying and hearing mind blowing things, but it seems to just open them up the experiencing epiphanies through nonsense
Neil Degrasse Tyson
Why I like this before I like it. I didnt push the like botón. Is this bikini bottom or W is a me mies no se dice mixe o ya. I love the B of your ideas. You whitey wait it guey. Blackys is bet er Black Kiss no. Never Just Kiss Block that Black. And Black list the wise man. That isnt something. You re sure right. May be anything as everrynhing sure. I luppi that style from a blamaste.
i just toked 4 joints and between tysons asperges and lord nices adderral ive found a gem of love and wholesomeness through shared wonder and passion
You guys are so funny. More so than any tv show I watch or movies, I consistently find myself laughing more watching StarTalk than anything else! Love it
I never thought _A Christmas Carol_ involved time travel; even the Ghosts clarify he's seeing Visions of what has transpired, is transpiring, will transpire [technically _may,_ as the future would be a choice; he was being shown *_a_* (possible) future that would happen if it had not been shown to him]...
I mean, it's possible they plucked the memories out of his head and showed them to him, since we're talking magic (ghosts). But the scientific explanation for seeing the past is photons from the past traveling forward to your retinas in the present (or, as they conjectured, you in a wormhole looking out at the photons from the past as they were emitted to see what was happening X number of years ago).
I hope to see and listen Brian Greene, and Michio Kaku in this program! All at once!
Very funny and informational episode
👽Great discussion as always Neil. Dr. Strange has a 'Stargate' creating ability of sorts not mentioned in the video. Knowing where to 'rip' spacetime for a desired location seems impossible. Another interesting topic from the movie interstellar not mentioned is the 'singularity' being inside the 4th dimension tesseract. I would love to hear your thoughts on this subject. Lastly, your thoughts on a possible scenario that we are not the first technological civilization that has inhabited Earth. For example, what if 100 million years ago a civilization left Earth knowing an asteroid was coming? The one that took out the dinosaurs. Cheers Blessings. 🙏
I was also going to talk about Stargate. They had to adjust the gate addresses to correspond to their new positions over time.
@@laridd Yeah, Another Great movie and show. Merry Christmas Larissa, Cheers, 🙏❤
Brian Greene and Neil best team
Mr. Sommelier may have actually sent Lord Nice Wine🍷 🥂 had he known he was communicating with a actual American Lord. Outstanding episode as anticipated #LordNice #Dr.BrianGreene #Dr.Tyson #TimeTravel #UntilTheEndOfTime
#RespectLordNiceTitle
(Shout out to Dr. Rick Marshall and Dr. Holly Cantrell "The Land Before Time") .Tachyons ROCK
This is the only thing that keeps me up. The explanation alludes me but I think I just got closer. Thank you. Time as a linear straight line is the problem . Time is not what we think it is at all, it's this movable feast
Got some equations to back that up?
Omg this is SOOO AWESOME
My favorite guest. Also Chuck and Neil killing it.
I really wanna thank you Neil and Chuck for all these videos and explainers, I think they're as informative as entertaining, and for me one of the most interesting content to find on UA-cam.
Send support from Mexico🇲🇽
For all the flaws within that movie, The Matrix: Revolutions put it perfectly: "you didn't come here to make a choice you already made it. you're here to try to understand why you made it". "Destiny" is just semantics. A person, under the exact same circumstances, will always choose the same path, hence "Destiny". I'm not even a scientist and It's obvious to me. The "destiny" of my 10 year old me will always be me.
Always love the episodes with Brian Greene - Perfect trio of entertainment and knowledge :D
I have seen this 3 times!! 😮 still fascinated about it!
Yes I believed everything you ever said👍🙏🎄 love your podcast thank you
It’s not really an option to “believe or not believe” these are simply scientific facts they are presenting and explaining.
@@MowSowearth is flat ur life is a lie
How about a scientific view on Netflix‘s time travel series Dark?
Yeah i think it represent really well that idea that you could travel to the past (and that you always do that) and fullfilled the causal chain of events
I love you guys. Nevermind the wisdom and knowledge you bring with every episode and every guest, but the sheer joy you give us is really something else. i love physics, mostly due to reading your books. but i somehow ended up as an MD.haha seeing your content always reminds me why i loved this field, and why i always will. You guys always bring order to my entropy. Cant wait to read Brian's new book during my down time in the clinic. Cheers!
Time travel does exist. Eg. You can send a message to yourself (or to someone else) at 2:58 AM on the day that the clock will be put back from 3 to 2 o'clock. You send the message at 2:58, and two minutes later, when it's 2:00 AM you see that you sent a message at 2:58... Another example. If you take a plane from Japan to San Francisco, you can leave on the 7th of January at 1:00 AM and you arrive 10 hours later in San Francisco at 6:00 PM on the 6th of January.
lol
I am a stage 4 cancer patient and I have taken and continue to take great comfort in this concept of immutable time. Thanks gents.
Mind Blown. WOW
What would happen to black holes if the big rip happened?
Am I the only one that finds all the giggling and all the unnecessary comments…just slows down the learning experience that is the only goal I have?
YES!
Yes.
Go read a book or watch one of the thousand lectures...
im really in love with time theories, really glad they do this. im sad I never found this channel before...
"How to Live Safely in a Science Fictional Universe", written by Charles Yu, is a favorite book of mine based on time travel. Really gives your mind a workout on understanding causal events.
So far so good...
3 of my favourite guys in Science...Neil and Chuck Nice...the Chuck D and Flava Flav of PHYSICS.
Brian Greene .... the Joel Olsteen of String Theory...I LOVE this movement!!!
love this podcast. it's fun, it's educational, it's inspirational, it's like a mixture of what I prefer to watch as a content in one package. it's just DOPE!
I love listening to smart people. I always come away just a little smarter, myself, thanks to these wonderful people who are willing to share their knowledge. Thank you, everyone. And remember, you can buy their books USED for a fraction of the list price, or even get your library to order a copy if you can't afford to buy them. While in school, I would spend lots of time at the library, reading things that I couldn't afford to buy.
why?
Absolutely brilliant. My favorite episode yet!!! Thank you!
20:44 i loved this question. Really interesting. Food for thought.
Photons being able to move forward & backward in time.
Brian is always great, and so are Chuck and Neil. Nice one.
I live in the City of Portsmouth in England, where Charles lived before writing is books. A Christmas Carol always struck me as a brilliant example of time travel.
In Interstellar there are 4 robots: PLEX, CASE, KIPP and TARS, being this last one the main one and which appears longer
For the record, in films and television with decent production budgets, we're now doing digital scans of actor's faces/body parts in order to create lifecasts to sculpt customized prosthetics on. No need for panic attacks or to be sedated anymore :)
Finally Brian Greene again! 🙌
42:25 this got me thinking, if you can use the black hole and hawking radiaton as a teleporter, you throw stuff inside one teleporter, shoot out the particles through space and gather them at another teleporter at different location and then read the information of the object it once was, and then reconstruct it
What a fantastic video. Great chat and very immersive. 🙏👌👍
Very smart talks, great team. Interesting way to engage people in a none boring way!
There were several publications between the release of "A Christmas Carol" (1843) and "The Time Machine" (1895) that explored themes of time travel:
1. "The World As It Will Be" by Émile Souvestre (1846) - This story involves a journey to the year 3000 using a flying locomotive
2. "The Clock That Went Backward" by Edward Page Mitchell (1881) - This story features a clock that transports characters back to the 16th century
3. "El Anacronópete" by Enrique Gaspar y Rimbau (1887) - This novel includes a machine that allows characters to travel back to various historical periods
4. "Looking Backward: 2000-1887" by Edward Bellamy (1888) - This novel involves a character who wakes up in the year 2000 after a long sleep
5. "A Connecticut Yankee in King Arthur's Court" by Mark Twain (1889) - This story features an American who travels back to the time of King Arthur
Yes please. Have Brian Greene as a regular guest.
