I just can’t get enough of these Doc Greene’s q&a’s! I must have listened these dozens of times and still every time I’m amazed by a thing I never thought of!! Thank you so much for doing what you do best: Inspire, educate and supercharge my imagination!
Such an act of generosity doing this series. Thank you Dr. Greene. In my late 60s I can still get my brain together enough to experience physics on a level and from a professor I could only have dreamed of all those years ago when I was in college. Thank you for all you do.
This is so much better than 'celebrities' talking about literally nothing. (Well, phyicists are allowed to talk about nothing. But you know what I mean.)
I can't thank you enough Dr. Greene for the time you set aside each day for these thoroughly enjoyable and enlightening sessions. More generally, your ability to communicate physics and cosmology to the world, here and in your talks, is unsurpassed. You are informed, intelligent, articulate, and engaging. That's a pretty good combination! (P.S. I am a semi-retired Canadian professor of psychology with a passion for both my own field and physics. So much to learn, so little time).
I'm sorry about about it and I'm just just just trying lol xx I need Yeah that's fine lol I'm just wondering how you can make money to buy cash and cash money or something to help out
For whatever it’s worth... you have an unusually rare gift for explaining complex theoretical physics... In my opinion your the best out of all Famous physicists... this information on the internet in this digestible form is precious I hope your comments give you inspiration and motivation to make as many videos as possible...
Sorry to hear about your mom, I hope she has a speedy recovery. Honestly these videos have done a lot for me during this time and I'm sure I'm not the only one. A HUGE thank your for spreading your knowledge. Sincerely, Your 13th biggest fan
Thank you so much Professor Greene. I'm a spiritual person as well. It's absurd to me to think that "brave" would be a descriptor of someone who says they're spiritual but this is the world we find ourselves in. The aggression I face any time I ask a question that makes folks think I'm spiritual is so in-your-face that sometimes I just don't ask. I'm ashamed to admit that. I have so many questions. Thank you.
THANK YOU VERY MUCH, Professor Dr. Greene, for all the shows you do, and to everyone that asked the questions, 59 yrs old and love physics, and your answers you answered a lot of questions of mine and a LIGHT BULB ON! I hope your Mom and Tracy and your kids are OK, BE SAFE !!
These Q&A formats are pretty cool eh? You got 5 minutes for a quick chat? Sure!Two hours later here we all are. The best type of distraction right now. So good.
I enjoy experimenting with the interactions of the particulate constructs of various cheeses with those of the human palate. Dr. Greene you are a truly remarkable human being, thank you for all your efforts and hoping for a speedy recovery for your Mom!
Prof Greene. As a Muslim I really appreciate your style. Although you are not relegious, unlike Dawkins and Harris, you don't ridicule anyone's beliefs. You seem to respect all people. Hope your mom gets better.
When it comes to taking in your thoughts and impressions about all things around us. Mr. Brian Green very fortunate. And enlightened when you finish. Thank you for the opportunity to expand my thinking. Please keep up the mind provoking expansion.
Thankyou for these thought provoking ideas. We are only human! Thank you so much for trying to help us understanding Sean! Someone said they wish they knew God's thoughts. Amen!
Love the way you encourage us to get a bootleg version of the PBS shows. Shows u care more about the general population learning, and less about money.
When You were on the Joe Rogan podcast, it was amazing! The fastest 2 and a half hours I’ve ever experienced, and I listened to it a second time as well! Thank you for sharing your knowledge and wisdom with us!
I can only repeat what others say. Wishing your mother a speedy recovery and thank you for your excellent series of videos during lockdown. I'm in the UK btw as you seem interested in where people are (30 miles south west of London).
Thank you Professor Greene for your generous and interesting insides on the most fundamental equations of Physics. I always wanted to know more about the String Théorie foundations, and I am waiting impatiently your daily equation on that subject. From Senegal, West Africa.
Professor you should explain in a series videos the great maxwells equation focusing especially on how 4 equation are able to predict a great deal in electromagnetism. You should perhaps in explain the origin of equations in little bit historical context so that one could grasp what experimental facts compelled scientist to construct such a theoretical structure to explain those facts.
Hi Brian, I am following your courses with great interest. I want to formulate the resonance system theory. I am working very hard to have the knowledge to prove it scientifically. Thank you!
It`s great that you had more time to take to educate us. Too bad I missed it (time-zones), I had a couple of questions prepared. Next time, I guess. Stay safe and keep up the great work!
Good Morning Dr. Greene from Smithtown, NY: 1) What kind of math / equation did Niels Bohr use to arrive that electrons are in fixed energy levels around the atom, i.e. are QUANTIZED. 2) Can anything be said about the velocity or acceleration of an electron around the atom ? If they are moving around the nucleus in a circular orbit (??) how come there is no emission of radiation, or are they not moving ? Thanks for your show and contribution to scientific education. -An Engineer & Scientist @ Soliton Hedge Fund
Hi Brian, love all your videos! and thank you for making them interesting. My question for you is, due to quantum entanglement and the appearing and disappearing of electrons have a relation to the “other world “ or some people call it “heaven” or could that phenomenon be a connection to another universe Where our double lives? Thx
Many thanks for every thing ..I hope that you if possible talk about conservation of energy and every relation between it and quantum mechanics from Shordenger equation to entanglement..and so on if possible
you might be shocked to know earth loses it's energy in form of some gravitational waves by which there is a chance that it may collide with sun after thousands of centuries.
Great material, Professor Greene. Could you clear up an aspect of Hawking radiation for me? If matter/antimatter pairs are created, is there any preference for which one of them is pulled into the black hole? Is Hawking radiation a net producer of matter, or of antimatter? Best wishes for your mom.
About "Light Falls": I am a Maine Public Passport member and I can get to the full transcript, but the video has been removed; no reason given. I have sent them a question about this.
I've missed a lot of these so I apologize if you've already addressed this. It would be nice if you had an index of the questions asked and answered with links to the video of the subject. My question refers to the Dirac equation. Can you please explain the concepts and implications of the Dirac equation and how it was derived?
Great session, thank you. Maybe you can explain the twin paradox one day. I'm confused about Brian and Evil Brian from Relativistic Mass Episode (06). There's a symmetry, Brain see Evil Brian moves slowly and vice versa... Which one is getting older faster??... I hope your mother feels better. I wish her this with all my heart.
Holy She@! This ur best video yet, Brian... uh, Sir. I've just now had so many ideas (visions) that i debated on even commenting (decided to make a video [audio] instead); but here goes nothing: 1.) I love ur take on the idiocracy of the modern, academic/industrial system of teaching details and ranking performance behavior instead of cognitive/creative capacity and bigger picture comprehension/level of inspiration ("to be "in spirit" of, and therefore willing to learn any, particular details, work hard, and to follow ALL company rules, even on ur off days and durings vacations). If any one company (like Apple or Tesla) finds a short-cut into tapping the fascist (or communist) versions of our capital systems for TALENT, rather than details or continuity of behavior and child psychology; then such a corporate trifecta of: Junior Jenius Jedi {baby Einsteins and "by-the-book" types; Kid Knights of Whizz {super hackers and rebellious types who COULD do the work, but feel no "motivation"; and the Silicon Valley Surfers {artists and free-thinkers, who would often do equally as well or even better in math or other "details"}, will totally rule over this world. I suggest that in "our" future; adult humans and parents of children should be paid to home-school in organic and online fashion, such as the child's own curiosity and passion for learning dictates. This variable pay rate would be based on the quality of the final product (education), quality of educational outcome (behavior of the child), and/or- the development of a suitable, foundational understanding or excellence of comprehension for a given industry or a specific, corporate sponsor (tax-payer). Such a transition away from the communist-style system of education would save money on road-repair (fewer Moms on the road, shuttling kids) and there would be no more buses to maintain, no more of these large, inefficient school buildings to heat and cool (which is also good for the environment). These advanced, liberal contestants for our tax-payer dollars could then be "hired" by the system, and directed towards a personality-specific, suitable industry. Only at working age or "age of maturity", would these kid geniuses then be given the specific, field-relevant, trade-secr3t, technical training- needed for their future employment. This leads me to 2.) if u think the FUTURE is the "big mystery" then u got more faith in the continuity of human civilization and technology than i do. I feel like the past is the "bigger mystery"- all of the books and videos of the past that I want to know about, read or see/analyze, have been destroyed by: fire, flood, natural disasters, Northern Invaders (library of Alexandria), Greeks, Romans, Catholics, and in recent decades, we have Nazis of all sorts of religions to do our book-burning and rewriting of history. History is written by "winners"- which is often the worst sorts of really brutal AND dumb, "believers" (who have never done an actual science experiment in their life). For example: Our Oil Kings are now-a-days denying that Thomas Edison invented and manufactured the lithium-ion battery, in it's current form. This modern, e invention is credited to a "John" somebody, a science professor from Texas, and a couple of imported, Japanese "assistants". I have found several, ancient, hard-backed textbooks and technical manuals that prove beyond reasonable doubt that nothing much of history class is even remotely accurate, nor worthy of your child wasting his time to learn. What was the "Antikythera mechanism" really used for, and who built it? What if somebody had followed in Charles Babbage's footsteps, and perfected the mechanical supercomputer, centuries ago? Lots of room for fiction and speculation in the past. Conversely: the future seems to never "change"- or at least cultures and human nature seems very reluctant to- which leads a great deal of predictability. If you want to see the future, just watch "The Simpsons" or "Futurama". These crystal balls function really, really well; seen that "the future" is any human timeline or political trajectory- all of which are "doomed to repeat itself"- unless inspired by an outside force (or large sums of "hush money", lobby money, war, civil war, social or environmental collapse). Add-in the advent of "deep-fakes" and AI projection, and now the "history" and "news" or videos of the past are wholly unreliable. The past is truly "unknowable", more "fun" to speculate about. 3.) I really liked your thoughts about the in-coming spacetime of expansion (dark energy) being related to negative gravity, dark gravity or apparent insufficiency thereof; possibly related to Casimir force or maybe the Higg's field itself. I'd love to hear more about these on-going experiments. Excellent video. I want to plug ur channel, and recommend Folks subscribe. I really enjoyed it a lot. Thanks!
looked away for a second and looked back at 4:22 and nearly lost my shit at the shape of Brian's hand, accidentally showing us part of his true alien form.
@WorldScienceFestival Is it possible to create smaller particle accelerators without reducing their effectiveness? The push towards better accelerators seems to be in the direction of bigger and bigger accelerators. There is a finite amount of land on earth, it seems to me that we are hitting a wall on the size or power sources that can be used to power it.
Hi Professor Greene. I respect your spiritual perspective and share your universal view. I also admire you as a great teacher. With respect to gravity, can you help me understand the curvature of 2D spacetime concept proposed in the general theory of relativity. If a mass curves spacetime, wouldn't everything be pulled towards one of the poles of the spherical mass in question. And wouldn't there be a tendency to repel objects that approach the mass from the reverse side of spacetime? What would you say about the possibility that the distribution of the Higgs particle is asymmetric and if energy or force-carrying bosons move through an area of high Higgs density during the early universe, and if they are able to interact with the Higgs field (eg by the ability to carry and transiently exchange a weak hyper charge (W+ boson), they gain sufficient drag to cause their mass to increase or spin to decrease (transforming some of them perhaps into fermions) which then leads to particle/mass formation with which we are so familiar. Gravity then would not be a necessary component of the early universe causing hydrogen atoms coming together in the early universe to form stars and galaxies. Gravity could certainly be the result of bundled energy (mass) from asymmetric Higgs distribution causing a curvature of spacetime not so much from the 2D perspective of a flat sheet but the 10D perspective of your string theory.
Please pardon me if this is silly. Does the distortion of time caused by the mass the earth is , resist the movement of earth around the sun. The question originates from how planets do not loose energy resulting in perinial motion. Again please pardon me if it is silly.
Could tachyons perhaps explain dark energy since you said when these hypothetical particles lose energy that they would speed up not slow down? Would tachyons have to be massless? If so I would guess they could not account for dark matter or is my understanding flawed? I hope your mother is doing okay. Thanks for these shows.
Not challenging, but you cite the years and the amount of knowledge since Einstein in the last 100 or so years. How can you be so free of time but so dependent upon it?
Hello, I was wondering Given that light/photons are affected by the force of gravity/mass, would that force also affect the velocity of light/photons? Passing into the Earths atmosphere and refracting slightly, as well as a reduction in speed. Could the gravitational pull increase the lights velocity, countering the reduction due to our atmosphere.
In the quantum eraser experiment; determining the slit through which a photon travels seems to obscure the wave interference pattern. What if the photon were split yet again and had 2 alternative observers, one observer reveals through which slit the original photon traveled and one observer remains uncertain, what would happen to the wave interference pattern?
Would it be possible that if Bell's experiment could somehow be configured with 4 points at 120° in a spherical arrangement that the results might end in an even number of variations such as 8 of 16?
Could the opposite side of the hawking radiation equation explain the expanding universe what are those positively mass charge atoms doing also could entanglement account for why it happens everywhere could we detect a fluxuation of expansion and calculate it to match the amount of black holes that exist at one time
@22:47 A friendly reminder of the great truth. Just because you can not imagine something within the scope of your understanding does not make it a nonfact. There used to be a time in mankind's understanding they could not imagine ever going over 100 miles per hour. Understand this, all flow is the same. there is not anything that vibrates that does not radiate to everything else, through the Higgs field, and in the Higg field, everything is in a state of vibration because of the Higgs field. Just because you can not measure a condition does not mean it does not exist. If you have no instrument to detect the root cause of a phenomenon, it puts it outside of your understanding, your dimensional awareness being unable to peer into the realm can not measure.
With regard to Hawking Radiation, I don't understand how the enormous gravitational pull of a Black Hole is not sufficient to swallow up the Positive virtual particle at the same time as the negative one-what propels it away from the Black Hole? it follows that there must be some force acting upon it unless I am completely incapable of getting some crucial point(s), will someone who actually knows kindly enlighten me? Thank you.
As much as civilization, regarding the sciences, has progressed in the last 200 years do you ever get the feeling we are really quiet ignorant about the workings of an infinite universe/multi-verse?
Hi, and additionally the time dilation problem, if either party can claim to be at rest, the others time will appear to be passing at a slower rate? There for, relative to each other, the same can be said about the time dilation. Is this just illusion? Or does the argument that at constant velocities either party can claim to be at rest, not apply. But on a galactic scale both are in motion, maybe due to the gravitational influence? Okay, we have two orbiting satellites, going in opposite directions. Constant velocity, no acceleration, will their time pieces record time at the same rate, why?
Brian tackled the question of human awareness (1'04'15) and Penrose's 'microtubules'. The "hard problem of consciousness" is how physical particles can give rise to the sensation of being aware, with all its subtle corollaries. Of course any discussion of this is speculation, but it is interesting to consider awakened, or self-realized individuals. They find this "problem" to be trivial, in the mathematical sense. Unlike in previous times, there are currently many self-identified awakened individuals, and their reported experiences are interesting. Our everyday conscious awareness is like the light of the Moon as compared with the light of the Sun of an awakened individual. They describe existence in a remarkably consistent way as consisting of one single consciousness, which serves as THE underlying reality. Animals, including humans, can then reflect that consciousness to greater or lesser extents within a universe and physical reality that is somehow based on the expanded notion of the one conscious awareness. What I mean is that our simple conscious awareness is seen as "creating" all the richness of our mind, our heart, our bodies, and our universe. The entire field of diversity, of change, is seen as somehow a dual form of the underlying oneness of absolute fullness, free of objects, events, or divisions. This realization is what is meant by "self-realization", it is a field of knowledge not based on the mind or on study, but based on consciousness and validated by subjective experience and experimentation. Physics, by contrast, is based on objective experience. Right now, it is hard to see how one side of this duality affects the other side, since they share no common attributes. The physicist David Bohm spent many years considering these issues in his friendship with J. Krishnamurthi.
Let's say that we're living in our glass and we nam every single sand in the glass how long would it take it to flip over again ? If everything is found. Forces the flip over For the emergence of gravity if it is found. 💧🎱
If all the energy that has gone into speculating about string theory had gone into extending and verifying the relatively simpler Bohmian Mechanics, just imagine what standard QM might be like today, freed of a few of its more mystical (unknowable) limitations...
