Ed embodies the humble, softly spoken, yet fiercely intellectual scientist, using his imagination to delve into the mystery of how the universe came to be. Putting out those Aristotelian 2.0 vibes.
Hi all - have seen comments for an against the text… I decided to write a little blog about it for those interested in the editing process… Link in the description.
Sixty Symbols I know I'm late on this reply, but my opinion on the the text is it would be perfect without the black background. Just the white text in a transparent layer on top of the video, perhaps smaller and to the side so it doesn't block the subjects face too much. As always thanks for your hard work on the videos!
love the longer format. perhaps there can be a balance struck between the short and long scale videos on this channel. also loved hearing him talk about exactly what he wanted to with minimal interruption, got to see a small window into how the professor's mental gears work. interesting how he said more than once that he continues and persists with this idea because of its "beauty". in a way i suppose artists and scientists aren't so different, they both deal in the constant struggle to convey truths. beauty seems to perhaps be a happy aftereffect. keep 'em coming Brady :)
I agree! And a lot of times the beauty is in the truth itself, as well as the approaches to discovering the truth, interpreting it, and even in simply the process itself. There's beauty as well in how the information is conveyed, represented, taught, talked about, joked about. Science is fundamentally a creative and artistic process, and just like art, science can be easily appreciated by most people if it's packaged the right way. However, just like art, there are also many things that are totally unapproachable except for the initiated. Can a layperson experience the feeling of playing a difficult piece on the guitar? That type of appreciation requires a specific technical ability. Science of course has many facets that are similarly difficult to appreciate.
I can imagine this man as actor playing serial killer talking about all his journey in jail ;) But seriously its pleasure to watch him explaining anything
ed's description at the end about how he would feel if strings didnt exist is just so amazing - we need more people like this. taking chances etc giving things a try. and if everyone took chances, not everyone would be right but its not about individual achievement its about humanity's achievement as a whole. so glad there are people who havent given up on string theory!
Ed is such an amazing person. I like his competence, his voice, that he is always smiling in enthusiasm and humility, how he can explain stuff, and that he blushes sometimes (note the red ears towards the end of the video). Such a brilliant and likeable person.
Love the explanation but the text was distracting. I wouldn't mind if they were animations supporting what the professor was explaining though. In fact animations would supplement the video.
Oh Please - more like this! Seriously - far more interesting to hear about the more advanced concepts - most of us are geeks and nerds, so we can follow. Loved the in depth explanation, I definitely see why all the enthusiasm to detect the defects now.
I play videos with Proffesor Ed on my phone as I sleep. His voice is like a warm blanket snuggling me to sleep. Plus, I swear I wake up each morning just a little bit smarter.
Ed seems like an amiable, charming fellow, happey for him winning the prize. Evan if no full comprehension of the advanced physics theories he speaks of, still enjoy the videos he is in.
The way Ed talks is extremely soothing and really makes you understand what he's saying or explaining. Some scientists/physicists speak in a rather smug or over confident way that is almost disengaging when they are trying to explain a point. Ed is the complete opposite and I could sit and listen to him explain anything for hours.
Ed Copeland is simply amazing. I can listen to him for hours... Great, great video again Brady!! I really appreciate your work and the professors willingness to talk about these subjects in a way that we can grasp the general idea. This is priceless for humanity!
I love whenever professor Copeland talks about what he's passionate or excited about, he gets a huge grin on his face, even if I don't fully comprehend what it is.
Hi Brady! I would just like you to know I loved the text questions and here is why: Sometimes, or quite often, it seems like your own volume is somewhat lower than the people you are interviewing. This sometimes makes it difficult to hear exactly what the question was. With text there can be little doubt. Also it's always nice to have a more or less uninterrupted torrent of science from Prof. Copeland.
I really enjoyed this format. It's just such a Joy listening to Prof. Copeland. It would be great if there were more videos like this, with the other professors as well.
There should be a Professor Copeland radio station and website. I could listen to him forever, morning, noon and night. Thank you for the in depth video. I am grateful for your time. I do not understand cosmic superstrings but what I do understand is your dedication, focus and hard work that defines physics to me.
Nice and smooth explanation Prof. Ed. Mesmerized by your voice and again..again I just want to listen your speech. and thanks to Bro Brady posted this video. from Malaysia.
some quality material right there ! things are called with their names and the fact that there are doubts about them and passion about them gives me hope that we eventually figure this out ! It is nice to see scientists like professor Copeland walking us through cosmology and terms ! Just by watching this video one must gain some intelligence , getting to know what is out there is at the very least incredible and interesting !
I went to Nottingham (Russian Studies.... Oh dear), and I'm now very proud. Numberphile, Computerphile, and Sixty Symbols are all great educational tools for 'interested people' (in the spirit of my favourite place, the British Museum). Well done, and congratulations from one of many alumni. Nice!
Congratulation on getting the medal. Fantastic video I really appreciate the time and effort that has put in making this. I personally think that the result will end up being negative. However I love the work you are doing and I really do hope I am proven wrong.
Something which I find cool is that maybe in the future Ed Copeland is one of those big shot physicists/mathematicians like Einstein or Pythagoras. And you can look at him explain things about in a simple way on the old ancient youtube library. Exploring these old 1080p videos with these horribly low bitrates and they're not even shot in VR. And you get a sense of how mankind was in certain ways the same despite of how primitive their technology was. The idea is just amusing.
Not reading through 456 comments so would not be surprised if this is not already flogged to death as a possibility..but.. given that the css's formed very early in an initial expansion event and that deep sky observation says SMBH's did too could they not be one and the same? Not whole strings perhaps but fragments of them. A collision of strings might cause such a gravitational well that drags in both or multiple pieces and/or lengths of strings resulting in the massive singularities we see. Strings with energy transferred to rotation would have their angular momentum maintained, at least to some measurable extent, and explain the uniformity (sigma) of rotation in spiral galaxies. Others, due to direction and impact velocity, would be cancelled out and form giant non-rotational elliptical galaxies. In the kinked string analogy used - if the kink always ended up on an inward facing direction, toward gravitational center it would remain very weak and hard to detect. And the structure of the cosmic web itself surely looks like a string vest! Whatever the truth a fascinating and inspirational video from a guy truly great at explaining "stuff".
I love professor Ed Copeland ...this is the best video explaining cosmic strings out there! and it is a mesmerizing watch worth watching a time or two extra, then revisited later.
My respect to the Prof. It takes all my knowledge to keep up with him, and these theories I have never heard of. I am SO looking forward to the other 2 videos. Please more LONG videos (like this one)!!
dear brady, as an aspiring theoretical phys student. i so so so much wish that you can have the chance to interview ed witten!!!!! thanks for this video. its greattttt
Could these cusps (not sure about how to write this..) I mean the ones that beam out gravitational waves be responsible for fast radio bursts, or are these not capable of loosing energy in the electromagnetic spectrum ?
Just wanted to make a comment about a thing mentioned by Prof. Copeland. It is true that the analogues of cosmic strings do exist in many Condensed Matter Systems (also including other types of topological defects, besides line-like ones). Actually these exist in systems most people have already seen! For example they exist in superconductors, where they are called "Abrikosov Strings" (Nobel Prize 2003). The so-called Meissner effect is the reason a superconductor levitates in the air, but it's these "cosmic string" like objects inside the superconductor that makes the levitation "stable". So without these strings in a superconductor, the amazing levitation demostrations would not have worked properly!
15:40 'You're just making this stuff up aren't you?' So brilliant, and the way Ed just ignores it is as brilliant. Reminds me of some guy named Ockham who just made up a razor out of thin air. But he never proved that it existed.
After watching this numerous times followed by me crying myself to sleep over my brain's inability to fully understand this concept, I think that I'll be quite ready for one of the next parts now :) Congratulations on winning the medal. :)
I've gotten to the point where there's too much good TH-cam to watch -- and then I stumble on a video like this. Providing such a long, deep dive for the layman is incredible, Brady and Ed. I think this is some of your best work that I've seen.
I've seen some comments saying that STring Theory is worthless - you should probably do some research. It's produced valuable work - regardless of whether it turns out to be our final theory or not - and it's not the most popular pursuit of theoretical phsyicists for no reason.
I think it would be interesting if more complicated videos were uploaded, here or on another channel. Things like showing the evidence of experiments and observations instead of explaining it in lamens terms. Even though I'd likely not understand a second of it, it would still be cool learning to appreciate how much work you guys do.
I did like the text though, because as Brady says, it helps breaking the video into parts like subtitles and make it easier to pay attention to. They are like booster dose that help us raise awareness, which is an inverse function of video time. In long video like these it can 'revive' our focus so that we don't fall into a state of glazing. If the latter happened, we feel really guilty, and have to watch the thing all over again.
I'm not going to pretend that this makes any sense to me... From my relatively primitive physics classes I've realized that it's impossible to visualize most of this stuff so i just trust the math. Math always delivers. Mostly.
I swear, I've almost grown to despise videos based around strings. They make me think too much, not in a good or necessarily a bad way. More of in a way that reminds me of when science grabbed me as strong as it could and said "LOOK, LOOK AT THIS... This is pretty neat is it not?". My first introduction to the String Theory was a NOVA video, and my immediate reaction was to grab paper and a pencil, and I was just starting out in Middle School. I've loved how far you can attempt to think outside of the box when attempting to understand how the Universe functions. I have to say what grabbed me the most out of this video was the gravitational influence the theory has. And then the fact that it can cut itself up into smaller pieces, and that they formed very very early in the universe, at a fraction of a second. It makes me wonder, if one of the reasons we can't see it is because it's there but isn't there at the same time? Perhaps just phased out enough to not heavily influence the things around it, but there enough to generate subtle gravitational pulls.
Wow superstrings - apparently really interesting objects! Congratulations to Professor Ed Copeland on the medal. It is always a pleasure listen Prof. Copeland at Sixty Symbols!
I had heard about cosmic superstrings a long time ago before the theory had been largely discounted by the CMB measurements, but I was unable to find anything about it in searches (everything I found was related to String Theory), and I was beginning to feel a little paranoid about it. So I'm really glad to have found this explanation of what the theory entailed. One the one hand, I'm slightly irritated by scientists who care more about the beauty of an idea than whether or not it's actually correct. But on the other, I'm glad that people continue to pursue unpopular ideas, because you never know where they may lead.
Love your channel and Professor Copeland's videos. Just started checking them out and am fascinated. Not a science person but these videos help me to understand. Thank you!
I love scientists who work on less popular, riskier investments. Even if they don't pan out, we get to now know that, thanks to them. Not to mention all the other research and discovery generated by the pursuits. Someone has to do that work, and science as a whole benefits from it. We owe a lot to them.
I would love to sit & talk with him about these subjects. He explains it so I can grasp the ideas. I can't do the maths but the ideas are understandable.
I was a skeptic about theoretical physics until I read Kip Thorne's book on the legacy of relativity in the 20th century. I have a strong appreciation for people like Professor Copeland. Nature is not this clean, simple perfect world. It does not fit in intuitive and comfortable bounds that make it easy for humans to understand. Even if his specific work doesn't smell right to me I don't think it shouldn't be worked on. What smells bad to me and everyone else might well be what nature is actually like. Even if it isn't the logical paths and narratives can be translated into future work. To push human understanding of nature it's not enough to just know a lot of things and it's not enough to just be creative. You need both and everyone needs to keep an open mind and listen to narratives that start from agreed upon base assumptions.
House of Pain's hit song addressed these ideas more directly in it's first draft. It was ultimately scrapped, however when the single did so poorly on the charts that a field of science was formed around the idea that one could sell exactly negative one-half copies of a song. The first stanza is written here: Flop around, By House of Pain "FLOP AROUND FLOP AROUND FLOP UP AND FLOP UP AND GET LEFT (or right. perhaps both simultaneously.)"
The professor +Ed Copeland has said that among those cosmic superstring those that are self-intersecting are the more common, but also they decay very rapidly. This may mean that those has dissapeared early on. On the other hand he did mention that the structure of galaxy clusters seems to resemble that of cosmic superstrings that don't self-intersect. And also that the primary way for those strings to lose energy is by gravitational waves. That may mean that those strings has been able to live long enough to rearrange matter but they have lost their energy in the process and that's why we can't find them. All in all, it seems to me that those cosmic superstring may has very well existed. But if they did, they no longer do. Just like the example of what will people think of stars in a universe in the theorical situation where the (ever accelerating) expansion have reached a point where all the stars are too far appart to see them. In that situation, people will probably say that stars have every right to be there, that the process in which they think of them forming makes complete sense, but still they don't see any evidence of them being there.
Good work on the medal, quite impressive. I myself have been following the progression of string (M) theory for a number of years now, and I am quite impressed with the work that's been done so far. I believe your work should prove quite interesting, and I cant wait until you or others reach some conclusion on the theory,
Fabulous talk. If strings can form over distances, then it is worth thinking about the possibility of strings formed between entangled particles as being mechanism of “spooky action at a distance”.
Thank you Professor Copeland! This was one of the most interesting lectures I have heard in quite a while. Interesting topic, and well explained! //Henrik,Sweden,Royal Institute of Technology.
What if inflation was the direct result of the superstrings disipating or dropping into the lower energy state of there surroundings, or that a bi-product of them radiating away there energy in gravitational and that the expanding waves increasing in physical size but decreasing their wave height like a ripple in a pond and like a ripple or wave in an ocean the galaxys embedded in the fabric of space time like a surfer on the ocean are being pushed along for the ride, and thebcosmic voids are the remnants of where former superstrings formerly existed? Please please give me some feed back on this, i love thought experiments, and my eyes opened to wrong ideas.
Physics like this is like a religion, but instead of just being an idea that is based on nothing but hope and thought, this is based on observations and calculations. It has not been proved or disproved, just as religion, but it makes sense that it's there.
one of the reasons i was never friends with physics in school was because of the ammount of "equation memorizing" that it involved... but since i started university (computer engineering) ive been reading up on modern physics without the pressure to "memorize or fail" ive been finding it so mezmerizing and interesting... I could probably watch videos like these for hours on end
thats one thing i find weird: some teachers make you memorize all the equations how i was taught was, you have a very small set of information and you just derive the equations. in gr. 11 we werent given an equation sheet cause you can just reason out all the simple equations (12 and 1st year were a bit harder... i still did it though cause it made my life easier) i literally went through high school up to most of first year without memorizing any equations but now i kind of have to because deriving them again during an exam takes too long, but its still easier to memorize things you understand fundamentally.
Awewsome!!!! the magnificent universe that enfolds us all. Congratulations professor Copeland for your medal and the nice and happy way in which you explained to us such complex concepts in a quite comprehensible way Thanks a lot

I love how Professor Ed Copeland explain things.He is calm and radiates positive energy.
and gravitational waves
A gentle soul
Do a two winding with a wider rubber band and see 180° flip.
I love listening to Ed Copeland!
I get so excited when science videos are tens of minutes long. More of these the merrier :o.
Professor Ed is my favourite by far!
Hi all - have seen comments for an against the text… I decided to write a little blog about it for those interested in the editing process… Link in the description.
Sixty Symbols I know I'm late on this reply, but my opinion on the the text is it would be perfect without the black background. Just the white text in a transparent layer on top of the video, perhaps smaller and to the side so it doesn't block the subjects face too much. As always thanks for your hard work on the videos!
'FLOP AROUND'
THANK YOU SOOOO MUCH FOR THESE VIDEOS. I HAVWE LEARNED MORE ABOUT SCIENCE/PHYSICS AND OUR UNIVERSE FROM THESE VIDS THAN IN 16 SOME YRS IN SCHOOL
@Nonprophet, that wouldn't help point 2 very much. I prefer the black background
would it be possible that cosmic strings are flows of neutrinos or something
love the longer format. perhaps there can be a balance struck between the short and long scale videos on this channel.
also loved hearing him talk about exactly what he wanted to with minimal interruption, got to see a small window into how the professor's mental gears work.
interesting how he said more than once that he continues and persists with this idea because of its "beauty". in a way i suppose artists and scientists aren't so different, they both deal in the constant struggle to convey truths. beauty seems to perhaps be a happy aftereffect.
keep 'em coming Brady :)
I agree! And a lot of times the beauty is in the truth itself, as well as the approaches to discovering the truth, interpreting it, and even in simply the process itself. There's beauty as well in how the information is conveyed, represented, taught, talked about, joked about. Science is fundamentally a creative and artistic process, and just like art, science can be easily appreciated by most people if it's packaged the right way.
However, just like art, there are also many things that are totally unapproachable except for the initiated. Can a layperson experience the feeling of playing a difficult piece on the guitar? That type of appreciation requires a specific technical ability. Science of course has many facets that are similarly difficult to appreciate.
Speaking of beauty, have you heard of Perfect Fourths tuning? You may find it interesting.
I love the idea that Ed Copeland sometimes gets quite angry.
Would’ve looked odd to me
I can imagine this man as actor playing serial killer talking about all his journey in jail ;) But seriously its pleasure to watch him explaining anything
I get the impression that if you were to genuinely disrespect him, he would destroy you.
Hes a passionate man
ed's description at the end about how he would feel if strings didnt exist is just so amazing - we need more people like this. taking chances etc giving things a try. and if everyone took chances, not everyone would be right but its not about individual achievement its about humanity's achievement as a whole. so glad there are people who havent given up on string theory!
Congratulations on the medal as well!
No matter what the results are, the observations made while trying to understand this can be important for other theories.
Ed is such an amazing person. I like his competence, his voice, that he is always smiling in enthusiasm and humility, how he can explain stuff, and that he blushes sometimes (note the red ears towards the end of the video). Such a brilliant and likeable person.

I play videos with Proffesor Ed on my phone as I sleep. His voice is like a warm blanket snuggling me to sleep. Plus, I swear I wake up each morning just a little bit smarter.
I do the exact same thing
@@RedXFitness there's dozens of us!
Ed seems like an amiable, charming fellow, happey for him winning the prize. Evan if no full comprehension of the advanced physics theories he speaks of, still enjoy the videos he is in.
I had to pause Brady just to say, this video's on screen text is fantastic. You are the best!

University of Nottingham must be a great place to work! Every single person there seems so pleasant, genuine and knowledgeable.
Prof. Copeland is such a joy to listen to. All of his videos exude a passion for physics that is genuinely contagious.
Loved the longer video format, more like this would be great!
Ed Copeland is simply amazing. I can listen to him for hours... Great, great video again Brady!!
I really appreciate your work and the professors willingness to talk about these subjects in a way that we can grasp the general idea. This is priceless for humanity!
diogo canina do you actually learn? So much info.
I know it is not for everyone, but I love the longer videos that allow Dr. Copeland to go into slightly more detail on the subject. Keep them coming!
Loving the HD and the text format!
Brady: love your work and listening to Dr. Copeland. These cut-aways to the block letters on a black screen are, however a little jarring.
I love whenever professor Copeland talks about what he's passionate or excited about, he gets a huge grin on his face, even if I don't fully comprehend what it is.

from Malaysia.
Would love a follow up on these videos with Ed!
So, what happens if a string passes the event horizon of a black hole? Is it like a kid eating spaghetti?
Well it will be much faster maybe :)
The string tension will probably break it.
I do know one interpretation suggests a time machine would be formed.
@Xavier: Which seems like further evidence that such strings don't exist.
Yes but the spaghetti becomes spaghettified.
some quality material right there ! things are called with their names and the fact that there are doubts about them and passion about them gives me hope that we eventually figure this out ! It is nice to see scientists like professor Copeland walking us through cosmology and terms !

I love the length of this episode! I can watch it while I am eating dinner :)
What he explains seems so out of reality to me that it almost feels like I'm watching a drug addict going into a mad hysteria or something.. xD
The great thing about you guys is-you show the the original papers which helped me cite them in my work.
I went to Nottingham (Russian Studies.... Oh dear), and I'm now very proud. Numberphile, Computerphile, and Sixty Symbols are all great educational tools for 'interested people' (in the spirit of my favourite place, the British Museum). Well done, and congratulations from one of many alumni. Nice!
Everything about this video is genius. Including the fullscreen quotes.

Sir I only wish I could reach even 1% of your accolade! You totally rock! Congratulations!!
The best half an hour ever. Will wait for next series and definitely will see it again. Thnx Brady, massively brilliant job.
Not reading through 456 comments so would not be surprised if this is not already flogged to death as a possibility..but..
given that the css's formed very early in an initial expansion event and that deep sky observation says SMBH's did too could they not be one and the same? Not whole strings perhaps but fragments of them. A collision of strings might cause such a gravitational well that drags in both or multiple pieces and/or lengths of strings resulting in the massive singularities we see. Strings with energy transferred to rotation would have their angular momentum maintained, at least to some measurable extent, and explain the uniformity (sigma) of rotation in spiral galaxies. Others, due to direction and impact velocity, would be cancelled out and form giant non-rotational elliptical galaxies.
In the kinked string analogy used - if the kink always ended up on an inward facing direction, toward gravitational center it would remain very weak and hard to detect. And the structure of the cosmic web itself surely looks like a string vest!
Whatever the truth a fascinating and inspirational video from a guy truly great at explaining "stuff".
You should do more of those, I like the format. 30 mins is just about right.
This one's going to take a couple of views to really sink in.
Congrats to Dr. Copeland for that medal!
Really good to hear Dr Copeland go into some detail. I would love to see more of these deeper expositions on Sixty Symbols
Professor Ed Copeland is my favorite professor on this channel.

One of the best sixty symbols videos so far and it reminds me of Stephen Baxter's novel "Ring"
2ot
Super stoked for the Professor!!! Congratulations to him for the award. I love these long ideas!!!
Imagine my surprise and delight at seeing such a nice long video after reasonably long break :) Thankyou sixty symbols.
Awesome video. Though I do think the abundance of random full screen quotes is a bit unnecessary.
Yes. Annoying full screen quotes are annoying…
_We apologise for the full screen quotes. Those responsible have been sacked._
I don't know, they help keep me focused. I'd actually prefer more illustrations.
I agree with Dennis. They're not random, they're emphasising specific phrases, and occur simultaneously.
I second (or whatever count it's up to) the opinion that the full screen quotes are unnecessary.
see link in the video description
What a fantastic video, this is the kind of physics that really gets me all fired up, wow !
Great video Brady! You should let the other professors "off the leash" some time!!
I did like the text though, because as Brady says, it helps breaking the video into parts like subtitles and make it easier to pay attention to. They are like booster dose that help us raise awareness, which is an inverse function of video time. In long video like these it can 'revive' our focus so that we don't fall into a state of glazing.

I'm not going to pretend that this makes any sense to me...
From my relatively primitive physics classes I've realized that it's impossible to visualize most of this stuff so i just trust the math.
Math always delivers. Mostly.
You can't trust math alone. If the math is correct but the experiments are inconsistent with reality, then something is wrong.
I swear, I've almost grown to despise videos based around strings. They make me think too much, not in a good or necessarily a bad way. More of in a way that reminds me of when science grabbed me as strong as it could and said "LOOK, LOOK AT THIS... This is pretty neat is it not?". My first introduction to the String Theory was a NOVA video, and my immediate reaction was to grab paper and a pencil, and I was just starting out in Middle School.

It makes me wonder, if one of the reasons we can't see it is because it's there but isn't there at the same time? Perhaps just phased out enough to not heavily influence the things around it, but there enough to generate subtle gravitational pulls.
Wow superstrings - apparently really interesting objects! Congratulations to Professor Ed Copeland on the medal. It is always a pleasure listen Prof. Copeland at Sixty Symbols!
Brady, Ed.. keep doin' whatcha doin'... you guys produce amazing works.
I had heard about cosmic superstrings a long time ago before the theory had been largely discounted by the CMB measurements, but I was unable to find anything about it in searches (everything I found was related to String Theory), and I was beginning to feel a little paranoid about it. So I'm really glad to have found this explanation of what the theory entailed.
One the one hand, I'm slightly irritated by scientists who care more about the beauty of an idea than whether or not it's actually correct. But on the other, I'm glad that people continue to pursue unpopular ideas, because you never know where they may lead.
Love your channel and Professor Copeland's videos. Just started checking them out and am fascinated. Not a science person but these videos help me to understand. Thank you!
I observed a face transition from :| to :D when you got the medal. Congrats!
I love scientists who work on less popular, riskier investments. Even if they don't pan out, we get to now know that, thanks to them. Not to mention all the other research and discovery generated by the pursuits. Someone has to do that work, and science as a whole benefits from it. We owe a lot to them.
he needs to be in a podcast, his talks are mesmerising
A half hour Sixty Symbols video... Christmas has come early!
I would love to sit & talk with him about these subjects. He explains it so I can grasp the ideas. I can't do the maths but the ideas are understandable.
I was a skeptic about theoretical physics until I read Kip Thorne's book on the legacy of relativity in the 20th century. I have a strong appreciation for people like Professor Copeland. Nature is not this clean, simple perfect world. It does not fit in intuitive and comfortable bounds that make it easy for humans to understand. Even if his specific work doesn't smell right to me I don't think it shouldn't be worked on. What smells bad to me and everyone else might well be what nature is actually like. Even if it isn't the logical paths and narratives can be translated into future work. To push human understanding of nature it's not enough to just know a lot of things and it's not enough to just be creative. You need both and everyone needs to keep an open mind and listen to narratives that start from agreed upon base assumptions.
When are we gonna get an unpdate on this? LIGO is working now, so maybe there's a new development?
If they had found them by now, we'd know about it.
This interview was great. I look forward to the next two.
House of Pain's hit song addressed these ideas more directly in it's first draft. It was ultimately scrapped, however when the single did so poorly on the charts that a field of science was formed around the idea that one could sell exactly negative one-half copies of a song.
The first stanza is written here:
Flop around, By House of Pain
"FLOP AROUND
FLOP AROUND
FLOP UP
AND FLOP UP
AND GET
LEFT (or right. perhaps both simultaneously.)"
And I just gotta say to Ed, it is awesome you taking up for Tom Kibble! ESPECIALLY since Tom came up with the Higgs mechanism.
I could spend hours listening to Ed talk
The professor +Ed Copeland has said that among those cosmic superstring those that are self-intersecting are the more common, but also they decay very rapidly. This may mean that those has dissapeared early on.
On the other hand he did mention that the structure of galaxy clusters seems to resemble that of cosmic superstrings that don't self-intersect. And also that the primary way for those strings to lose energy is by gravitational waves. That may mean that those strings has been able to live long enough to rearrange matter but they have lost their energy in the process and that's why we can't find them.
All in all, it seems to me that those cosmic superstring may has very well existed. But if they did, they no longer do.
Just like the example of what will people think of stars in a universe in the theorical situation where the (ever accelerating) expansion have reached a point where all the stars are too far appart to see them. In that situation, people will probably say that stars have every right to be there, that the process in which they think of them forming makes complete sense, but still they don't see any evidence of them being there.
Most of science is failure, but it's on those failures that success is built.
+ForeverOfTheStars All models are wrong; some models are useful.
Good work on the medal, quite impressive. I myself have been following the progression of string (M) theory for a number of years now, and I am quite impressed with the work that's been done so far. I believe your work should prove quite interesting, and I cant wait until you or others reach some conclusion on the theory,
Awesome. Thanks for the long video.

Oh look the humans finally started kindergarten
Fabulous talk. If strings can form over distances, then it is worth thinking about the possibility of strings formed between entangled particles as being mechanism of “spooky action at a distance”.
Thank you Professor Copeland! This was one of the most interesting lectures I have heard in quite a while. Interesting topic, and well explained! //Henrik,Sweden,Royal Institute of Technology.
What if inflation was the direct result of the superstrings disipating or dropping into the lower energy state of there surroundings, or that a bi-product of them radiating away there energy in gravitational and that the expanding waves increasing in physical size but decreasing their wave height like a ripple in a pond and like a ripple or wave in an ocean the galaxys embedded in the fabric of space time like a surfer on the ocean are being pushed along for the ride, and thebcosmic voids are the remnants of where former superstrings formerly existed? Please please give me some feed back on this, i love thought experiments, and my eyes opened to wrong ideas.
I've watched this multiple times and Im still having trouble comprehending this :/
Channels like these are really great. Very grateful to be a subscriber. :)
Physics like this is like a religion, but instead of just being an idea that is based on nothing but hope and thought, this is based on observations and calculations. It has not been proved or disproved, just as religion, but it makes sense that it's there.
Fantastic video Brady! keep em long, this is packed with some great stuff
one of the reasons i was never friends with physics in school was because of the ammount of "equation memorizing" that it involved... but since i started university (computer engineering) ive been reading up on modern physics without the pressure to "memorize or fail" ive been finding it so mezmerizing and interesting... I could probably watch videos like these for hours on end
thats one thing i find weird: some teachers make you memorize all the equations
how i was taught was, you have a very small set of information and you just derive the equations. in gr. 11 we werent given an equation sheet cause you can just reason out all the simple equations (12 and 1st year were a bit harder... i still did it though cause it made my life easier)
i literally went through high school up to most of first year without memorizing any equations
but now i kind of have to because deriving them again during an exam takes too long, but its still easier to memorize things you understand fundamentally.
I'd like to see a video juxtaposing him expounding on the nobility of this theory versus the politics of getting awards in science
Awewsome!!!! the magnificent universe that enfolds us all. Congratulations professor Copeland for your medal and the nice and happy way in which you explained to us such complex concepts in a quite comprehensible way
Thanks a lot
FLOP AROUND! best battle cry, ever. Love the captions. Congrats Professor Copeland.
