Thank you mister Greene for this video and all the others videos on RUclips to give us access for all this knowledge. From a "simple mind" trying to understand the universe. Watching you From Brussels in my bed at night. With all my respect, Miro
As a lay person with no education in the sciences, you have inspired me to search for scientific knowledge. Thank you for your excellent presentations. They are ALWAYS my #1 choice.
Saul seems like such an amazingly nice guy. Love his smile, enthusiasm and warmth. Why IS it that mathematicians and physicists especially among scientists are so nice as people. A certain type of wonderful character seems to be unusually over represented in these fields.
In the meantime the militry went insane by the information contained in the ancint scrolls that is telling them more of who we are thn anything found using telescopes...
@ char c, I wholeheartedly agree. There was an interview of Edward Witten, one of our generation's exceptional thinkers, which displayed a gentleman who is "so nice" and accessible. 🌺
Yes this was a great talk, like listening in on a conversation between amicable fella’s, Saul is a Nobel laureate but not at all stuck up about it, really a person who enjoys what he does.Brian does a really good job with timing the conversation , both have a ‘natural philosophy’ viewpoint that that’s easy to ascribe to. Thanks for an enjoyable talk.
Brian, I am going through cancer treatment and find these deep science conversations very comforting . I started a family and business at a young age and always had a regret that I didn't have the time to pursue my interest in science, you have helped me close that gap and I sincerely thank you.
I don't believe in role models or heroes, but Brian Greene, you would be the closest thing to it. Not only do you inspire me and my whole family in particle and astrophysics, but I try to copy your cadence and presenting enthusiasm in my own business presentations when presenting complicated topics to laypeople. I would love to have a beer or coffee one day with you!
I learn a lot from him..through his website-RUclips channel. Dr. Brain...Not..just a physicist person-He's also the best explainer of our & beyond our understanding-Complex universes being out-there?.
I really cannot imerse myself into any other podcast even irrelevant to space/biology after listening to Brian lol. Maybe I should start with Alan Watts to reset myself lol.
Hey Brain, My names Sam and I just wanted to tell you I really enjoy your speeches on particle physics and string theory. You’ve helped feed my interest on string theory, the universe, the multiverse, and really just science in general. You’re a really genuine guy and I gotta tell you I mean it. It’s refreshing to have a communicator in science be as clever and well spoken as you. I really enjoyed this video. I have learned a lot from you and would maybe even like to be a physicist one day. I look forward to future World Science Festival events and hearing your talks. I would really like the chance to catch up with you in person one day!
Hi Brian Just wanted to say I absolutely love your videos, tho I may not always be able to see you live I always catch up. I would also like to say thank because after my son took an interest in the world science festival he is now into his 2nd year at university studying cosmology, physics & astrophysics we are all so proud of him and in part you played a role in that to so thank you so much from one father to another. Kindest Regards Simon from Warwick in England
Wonderful interview. As always it has been a great treat to see this video. Dr Perlmutter's energy, warmth and character comes across fully. He appears as a great role model for future scientists. You both should be proud of your mutual commitment to educate the public in including a more scientific approach to solving problems and discussing all kinds of issues, particularly in these trying times. Thank you.
Brian, 1. You have such a beautiful mastery of the spoken language and 2. You are a very patient and thoughtful interviewer. Thank you for sharing your intelligence and gifts with us.
I love that there is such contagious enthusiasm from both born of simply wanting to know how reality really is. Loved the discussion, could listen to both Professors for hours and hours, keep up the fantastic work gentlemen.
There are a lot of really amazing scientists which did not get any relevant publicity. The really capable are few, and not all of them went into physics. Also there are a lot of guys on RUclips explaining pseudo-science or half truths or having understood the topic completely wrong themselves. On the other hand there are also ingenious non-mainstream ideas, which get ignored or denounced by mainstream scientists. Also consider many Nobel price winners not really being all that capable or having made their discovery by pure sheer luck/coincidence. I wouldn’t be wanting to listen to them.
Awesum job as usual Brian. The questions u ask and the way that u ask them just set Mr Perlmutter off in such a way that it excited him all over again about the amazing work he has done. Great job. Thank u so much.
I asked Lee Smolen this question earlier but haven't heard back yet: I've been having this debate with colleagues for more than 30 years now, and would like to close the chapter on it. I came across your writings and realized you might actually know this one. If you have a minute the question is this. Simply, an event that generates a photon, creates an EM wave packet of a quantized energy amount (frequency), which then travels to the detection point elsewhere in the universe along a straight line. That much we agree on. Thing is, it's an EM wave packet, so what shape is it? Does it radiate out in all directions like a radio wave, or does it have a direction vector which forces it along a specific path? The reason for asking is this. All the photons ever produced that have not yet hit anything are still traveling through the universe. They all contain packets of energy and their concentrations are higher in the centers of galaxies, so how much energy density is there per unit volume of space for all of the photons that are currently passing through that space per unit time? Sounds easy right, until you remember that the space is full of photons that have traveled from all of the stars that are visible from that volume, for all of the universe that is visible from that volume, not just the ones that strike a detector, but all of them. So say for a unit volume of space the size of a single atom, how much energy is currently passing through that volume from all of the stars that are currently visible from that location? It gets worse if you move an atomic diameter in any direction and check again, the same star is still visible one 1 angstrom , left or right! Has there been any measurements done by experiment that give us the true density of energy per unit volume from anydirection. Yes the CMB is measuring the concentration, its intensity, but I don't think we are taking into account just how much of that energy has already started the journey but currently has not yet been observed. The real question comes after you figure out just how much energy concentration there must be between galaxies that we haven't yet counted, since it must be having an effect on the speed (red shift) and also the expansion of space since it is getting less dense, which lends itself to the speeding up of the expansion of the universe by deduction. I never really got the opportunity to work with engineers and scientists that would even share the knowledge amongst their peers through my working life, and sadly one still finds that rivalry today. That said I now have time to think this through further and would appreciate the opportunity to talk to you if you will, further on this subject, it might even lead to a reason why EM radiation gets RED shifted, which is weird unless time itself is stopped at the photon entity. Faithfully
@@greg5023 Thanks Greg, I know its a bit of a stretch for the intellect but it feels very much like the question is bumping up against a knowable unknown. Lets just say I feel it in my bones. For example the CMB was once visible light, so what was infra red that was released at the same time, is that now radio waves? We are not measuring the true density of energy per unit volume of space and until we do we cannot estimate the true density of the residue. I’d like some help to shake the tree and see what falls out, are you up for a short proposal paper?
As one of those just clicking around various RUclips channels that look interesting, I found this discussion fascinating and very informative. I look forward to future conversations on our understanding of science and our universe.
I thoroughly enjoy listening to your shows, they're very informative and keep me up-to-date on cosmology and physics. However I have a problem with the volumes on your show. A lot of the time you are much louder than your guest and I have to turn up my TV so that I can hear what your guests have to say, making you seem like you're yelling and people complain that I have my TV too loud LOL. Could you please have your technicians work on equalizing the volumes it would be much appreciated. Thank you. I will keep listening no matter what but it would make it much easier for me to understand what your guests are saying without blaring the TV.
DR. Brien, You're the greatest teacher for younger generations & still inspiring so many peoples - Like me to go back to university & finish whatever I leftover!.. Dr. Brien, My biggest problem is English. Now I'm paying more attention to my biggest problem first... before even trying to go back to university to claim what I want. God bless you Dr. Brien...stay healthy, safe & happy. I wish you a long life.
We are so lucky to live in an age where acsess to education of this calibre is but a click of a button away... Professor greene is one of the greatest educators to have ever lived.. And here I am being taught by him.. Crikey
Hello. Thank you so much for a really fascinating and informative discussion. It is always a pleasure to watch your talks - so inspiring! Best wishes. Joan Nagase, Manchester, England.
I love that the whole research team got to enjoy the Nobel hoopla. Yes, Saul and a few others names went down in history. But you can bet there was a lot of pride in those people who took part in the research and made the "collaborative" effort succeed. They mattered too.
Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it."
great conversation brain i started watching these because i watched a show on netflix with you in it and then your utube and i cant stop watching them. I am not a student of physics but i wish i did go into this when i was young. to me the universe is the greatest fairy tale that came true i looooooove this stuff .
A satisfying explanation of the universe and reality is having two Ashkenazi Jews holding talks with a Hainanese Jew(Wong Chong Boon, with a past life of Ashkenazi) in Singapore.
I'm so grateful for the amount of time and money the USA uses for science and exploration of the universe. You are always ahead of everyone else. Not to mention that you have a company without tax dollars (SpaceX, correct me if I'm wrong) heading to Mars, that's unbelievable. Greetings from Europe!
I have some perplexing questions and hope that Brian or someone as knowledgeable can answer. Regarding multi-universes, I don't know how but I strongly lean toward believing that the multi-universes exist right here in front of us. The event that happened that made me start to research quantum physics is about 4 years ago as I was stopped at a red light in downtown Salem, Oregon, I saw a woman appearing to be homeless at the sidewalk, getting ready to cross the street. As I watched her, all of a sudden, everything about her stopped. Completely stopped. Her clothing stopped movement, nothing on her or a part of her moved. Everything else around her was in normal movement. I was really shocked and looked around to see if anyone else saw what I saw. There was a man, across the street from her to my right, he appeared to see her and then looked straight over at me, still at the red light. Then what he did is he turned around, looked up at the building right behind him, then looked back at her. After I saw him look at her, I looked at her and right at that moment, her action continued. That event stayed with me. I didn't obsess over it but I would think about it from now and then. After I started researching physics, the thought came to my mind that perhaps, multi-universes - string theory - all that is right here, not in some far place in the universe. As time as gone by, my hypothesis has remained and I've run into a conflict. Laying aside that I may have hallucinated this, and including what I've come to believe about physics, here is the problem leading to my questions today. I'm going to try and explain it as simply as I can, no matter how bizarre it sounds. If multi-universes are right here, that would explain the differences in what people believe nowadays. For example, those who believe in trumpism and those who don't. It was so bizarre to me that those who call themselves Christian yet support people like Trump and the like. It's just not explainable. Trump's character is the opposite of Christs. This is just one example. There are many unexplainable things that people who seem sane, believe in which are blatantly insane. It dawned on me that perhaps it has something to do with multi-universes being right here. In their universe, different real things are happening that are not seen in our universe. Another example, Joe Rogan may have died from covid in our universe after being anti-vax and all, maybe he didn't die in a different (non-seen) universe, that's right here. So, in reality, if this theory is right, that's why there is so much conflict with us right now about what is truth and what isn't. So, again, if this is true and we live in multi-universes every day, how do we deal with it? The only thing I can think of is to just not question another's mindset on something that I think is hogwash. I have good friends and even family who are in a different world in what they believe and no talking or reasoning can change their beliefs. I would like to have constructive opinions and responses about this. I do know what I saw a few years ago and I haven't seen anything like it since, so I don't believe it was a hallucination and I do believe we are living in multi-universes right here, right now. I do believe in Christ and I believe he is revealing many of his secrets at this time. I don't think the earth will ever be destroyed, God loves it. I don't believe in eternal hell fire as God is compassionate and forgiving. I do think that it's possible that for those who are just simply evil and have no love in them, they will just cease to exist, or perhaps sent to a universe that teaches them what it's like to be the recipient of the harm they caused others here. I realize that I'm throwing much out there that took me many years to realize so it all may sound crazy but I'm speaking from what I've experienced, read, researched, and from trusting Christ to teach me what he wants me to know.
I`d like to ask Saul Perlmutter: About Dark Energy, isn`t it just intergalactic dust that you are measuring but not taking account of when you calculated the brightness of distant Type II stars? Conservation of Momentum is an important law of Physics and I just can`t break that law.
Degrass Tyson & Brian Greene are collaborating on a new book: The Blackhole Ego. Available on Amazon and everywhere frayed string theorists books are sold.
SPIRAL cosmological redshift and model may be the way forward in cosmology. SPIRAL reconciles quasi steady state and big bang. If SPIRAL cosmological redshift hypothesis a hyper-dense start, with hyper-dense proto-galactic formation PRIOR to hyper cosmic expansion, with the universe attaining mature size and density within 4/365(5782) a fraction of history. Reference SPIRAL in the Pearlman YeC series for the alignment of Torah testimony, science and ancient civ. volume II.
There is no ongoing cosmic expansion, so no need for dark Energy. See SPIRAL 'GRIP' hypothesis on galactic rotation why no existing Dark Matter at play.
I had never before heard a renown theoretical physicist use the word "why'. I wish Dr. Greene would have elaborated on the intermingling of his "how's" and "why's".
Why don’t I get the option to get the subtitles? It is very annoying - I cannot hear what Saul is saying, his voice is not clear for someone who is hard of hearing - very frustrating
Thanks for teaching me that time travel is possible in theory. It would be very interesting to actually know what happens when you go faster than the speed of light.
If we would play with guessing ..? Why not ? As the photons have reached eternity, time zero, at higher speeds the time must then become negative So backwards in the past? Probably impossible .
I think if you went faster than the speed of light and survived everything would seem really slow if you could even perceive reality under light speed at that point. it seems that you can go forward or backwards it just depends on your navigation 🧭. most probably you would just show up in a different time, the future or the past with out proper navigation 🧩.
I study physics and Blackhole. I am a painter artist. I have a series of painting about Big bang and Blackhole. I like to share my black hole painting with you. Where can I send it to you? Thanks.
Are you familiar with Marina Jacobi? She has channeled numerous quantum equations and concepts having to do with healing oneself. I’m curious to know your opinion. 🙏❤️

Amazing discusion, I think every nobel winner should get a minimun 1080p webcam bestowed upon them with the prize.....:)

There are a lot of really amazing scientists which did not get any relevant publicity. The really capable are few, and not all of them went into physics.
Also there are a lot of guys on RUclips explaining pseudo-science or half truths or having understood the topic completely wrong themselves.
On the other hand there are also ingenious non-mainstream ideas, which get ignored or denounced by mainstream scientists.
Also consider many Nobel price winners not really being all that capable or having made their discovery by pure sheer luck/coincidence. I wouldn’t be wanting to listen to them.
Thx World science festival and contributors for bringing this content to all who seek knowledge and understanding. Your appreciated !

It dawned on me that perhaps it has something to do with multi-universes being right here. In their universe, different real things are happening that are not seen in our universe. Another example, Joe Rogan may have died from covid in our universe after being anti-vax and all, maybe he didn't die in a different (non-seen) universe, that's right here. So, in reality, if this theory is right, that's why there is so much conflict with us right now about what is truth and what isn't. So, again, if this is true and we live in multi-universes every day, how do we deal with it? The only thing I can think of is to just not question another's mindset on something that I think is hogwash. I have good friends and even family who are in a different world in what they believe and no talking or reasoning can change their beliefs. I would like to have constructive opinions and responses about this. I do know what I saw a few years ago and I haven't seen anything like it since, so I don't believe it was a hallucination and I do believe we are living in multi-universes right here, right now. I do believe in Christ and I believe he is revealing many of his secrets at this time. I don't think the earth will ever be destroyed, God loves it. I don't believe in eternal hell fire as God is compassionate and forgiving. I do think that it's possible that for those who are just simply evil and have no love in them, they will just cease to exist, or perhaps sent to a universe that teaches them what it's like to be the recipient of the harm they caused others here. I realize that I'm throwing much out there that took me many years to realize so it all may sound crazy but I'm speaking from what I've experienced, read, researched, and from trusting Christ to teach me what he wants me to know.
Such enjoyable humans! Keep contagious....
I`d like to ask Saul Perlmutter: About Dark Energy, isn`t it just intergalactic dust that you are measuring but not taking account of when you calculated the brightness of distant Type II stars? Conservation of Momentum is an important law of Physics and I just can`t break that law.
Thanks 🙏
Refreshing change from listening to Degrass Tyson interviewing himself.
Degrass Tyson & Brian Greene are collaborating on a new book: The Blackhole Ego. Available on Amazon and everywhere frayed string theorists books are sold.
Love this format. Feels amazing like Start Talk with Neil deGrasse Tyson but on other (lighter) spectrum ^^
Greetings fellow sciencers from Cape Town
58:43 exactly :-) nice to hear from you. Thank you RUclips/Google+++ for freeing up access to information from all sourced to production.
saved to watch later.
so far so good.
SPIRAL cosmological redshift and model may be the way forward in cosmology.
SPIRAL reconciles quasi steady state and big bang. If SPIRAL cosmological redshift hypothesis a hyper-dense start, with hyper-dense proto-galactic formation PRIOR to hyper cosmic expansion, with the universe attaining mature size and density within 4/365(5782) a fraction of history. Reference SPIRAL in the Pearlman YeC series for the alignment of Torah testimony, science and ancient civ. volume II.
1:20:00 If SPIRAL no Dark Matter and Dark energy predicted, so neither required. So no reason to assume there is any of either.
There is no ongoing cosmic expansion, so no need for dark Energy.
See SPIRAL 'GRIP' hypothesis on galactic rotation why no existing Dark Matter at play.
How does time dilation affect our ability to measure at long distances if at all?
welcome back!
edit: is this live??? or is schrodinger dead?
I love that line, The fun is in the mystery.
I had never before heard a renown theoretical physicist use the word "why'. I wish Dr. Greene would have elaborated on the intermingling of his "how's" and "why's".
Thats a very interesting point, faster cheaper development, I kinda like that idea..
What is going to be seen the view image from Webb telescope compare to hubble??
Why don’t I get the option to get the subtitles? It is very annoying - I cannot hear what Saul is saying, his voice is not clear for someone who is hard of hearing - very frustrating
For just a moment, I thought the video intro pic was of Brian Greene and an older Brian Greene 🤷♂️
Off topic but you two could be brothers!
Genuinely funny scientist. Never thought a physics Nobel laureate could be this funny.
Fascinating
The expansion happens before we look at it but it is the observation that forces the effect.
Delayed choice and the quantum eraser
can time be considered continuous or discrete?
Does World Science Festival need any help with Video Production or Content creation? I've got some ideas!
Thanks for teaching me that time travel is possible in theory.
It would be very interesting to actually know what happens when you go faster than the speed of light.
That question doesn't make any sense. You might as well ask what happens when you go slower than standing still.
If we would play with guessing ..?
Why not ?
As the photons have reached eternity, time zero, at higher speeds the time must then become negative
So backwards in the past?
Probably impossible .
There's no known way to accelerate over the speed of light. In theory you'd travel backwards in time, but as stated, you have no way to get there.
I think if you went faster than the speed of light and survived everything would seem really slow if you could even perceive reality under light speed at that point.
it seems that you can go forward or backwards it just depends on your navigation 🧭.
most probably you would just show up in a different time, the future or the past with out proper navigation 🧩.
My brain ALWAYS reads it as cosmetology first.
You must be very interested in the makeup of the universe. 🤣
beautiful picture.. i need one!
我層經 在2002年 墨西哥城，一所 青年旅舍，遇上 Dr Saul，和 他的 學生团。
希望 他 和 他的 學生，也能 記得 我。
I study physics and Blackhole. I am a painter artist. I have a series of painting about Big bang and Blackhole. I like to share my black hole painting with you. Where can I send it to you? Thanks.
Are you familiar with Marina Jacobi? She has channeled numerous quantum equations and concepts having to do with healing oneself. I’m curious to know your opinion. 🙏❤️
It's good to talk about stuff.
But it's bad to listen to Brian Greene's fraying string theories.
I would really like you to interview Walter Thornhill and some plasma cosmoligists. Be the guy who talks to them instead of ignoring them.
The economic principle: "Sunk Costs." Upfront losses, accepted because of the long term benefit.
Could the tension be the emissivity (a correction factor) of the universe? The detectors are of the same family that reveal and measure emissivity.
