Lawrence Krauss is someone I have followed for 20 years and he's changed my life because the discussions I can now have, my views on the world can be more insightful, and universe and life can be more interesting than ever imagined. I only understand Physics (the concepts) when Lawrence talks about it and i've listened to everyone. Hes changed my life for the better, more than people I am 'most close to'. I have missed Lawrence's video uploads / involvement the past few years. I always think when I hear things about Science and Physics that Lawrence would have a lot of interesting things to say about that. Thanks for the way you put your vast knowledge across and nobody else has the sense of humour, can crack jokes like you and be brutally honest and not afraid to speak their mind like you do. A lot of scientists try to be too nice and you can tell are reigning in a lot of their true thoughts in case of upsetting 'the other side'. With Lawrence WYSIWYG and nothing can compare with that way of being and the honesty knowing he is leaving nothing behind. Thank you Lawrence for being to me, the greatest physicist that's ever lived and I've ever experienced. Please keep producing these videos too if possible, they are great. I like the difference of these more peaceful videos where you have no external interference compared to the lectures, debates, discussions you used to do with illiterate peasants and you're probably fed up with them as I expect they can be frustrating and use a lot of energy (forgive the pun). You put everyone in their place so I expect that ships been sailed. If nothing else, just keep on making these videos talking about what your passionate about because it shines through. I cant imagine how hard work it must be to do what you do along with how busy you must be, but all I know is the Universe needs you, and so do I. Thanks again.
Lawrence 🙏I must say this is probably one of the top 3 RU-vid videos of my life. This is so inspirational and exciting. Now you motivated me to study even harder. Thank you sir!🙏👍🇺🇸🙏🇰🇷😊🙇
Thanks again Lawrence for opening up and telling us about the questions that most interest you at the moment. But there is something that I would like to mention that for me on a personal level, is quite important and that is someone who leads by example. Your 'feet on the ground' humble approach to teaching Physics, science in general and other topics, not getting sucked into the point scoring ego boosting 'big question' or 'big ideas' discussions, I think is the reason why we are so eager to follow you on your journey to discover the answers to the questions that most interest you at the moment. Thanks again. Take care.
Great dynamic sound bite on multiple complex topics - a real burst of enthusiasm and escapism we all need to stimulate our thoughts and love for physics
Your comments about what drives scientists reminded me of a quote from Isaac Asimov: "The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny."
you are the reason i was able to articulate my reasons for not believing in superstitious nonsense. since the age of 8 or so i saw my dog die. lucy was a red doberman and was truly innocent yet she suffered greatly. what manor of god would do such a thing and claim to be the arbiter of mercy and justice? i always knew it was bullshit and never had a good argument when i was young. as i got older my interest in science finally came about in my early 20s, a bit late but better late than never. before that all i cared about was hp lovecraft mythos and music production. well after years of being an irresponsible ass and being homeless off and on (without drug problems i might add which makes it seem even dumber) well in the depths of my desperation clawing my way up from nothing, your voice, among a few others guided me, reminded me i had a decent brain and maybe could carve out a purpose for myself after all. while i feel it may be too late for me to make it back to school and actually devote myself to physics like i planned/wanted desperately life hasnt really allowed me the chance to disengage the servitude of living check to check and constantly worrying about bills etc. but i at least have regained my time for music production and have been working on expanding the lovecraftian mythos and am still a science hobbyist. my story is boring though, but i felt the need to thank you for what you have done for me, you will always be a powerful ally to progress and the rational world! love you man and please keep going!
God is historically smth behind our understanding about things that are happening locally, that is, justified violence, or what to do with evil tricks of others (answer: celebrate defeating that others), etc. P.S. God had no choice. I believe Meillassoux' contigency explains that well. And each actual moment has to have a reference point, therefore this shape
Dr. Krauss; you mentioned many vs. a unique world. In an alternate world, what laws of physics would you change or create? In other words, what different laws are out there that you would find uniquely interesting that don't already exist?
When we tries to find out the ultimate laws of nature, a way of looking this as the nature trying to understand itself. We are the part of it, what parameters decide that we can understand that universe of which we are a part? Understanding this endless cycle may require different form of knowledge, its so puzzling and that makes it so interesting.
How do we so sure that Big Bang is a one time thing, instead of pulses interval? Each pulse creates a universe of its own, pushing and pulling one another accelerating? This did not come from educations of any sort but stayed at home since February.
I did have a serious question, I'm concerned about our society (maybe more the US than here in Canada) and it's changing attitude towards science and fact, (ex rightish leaning groups and their virus response in the states) if you have any current thoughts that you'd like to share, I bet a bunch of folks are interested.
I am concerned too.. I have talked about this a lot.. my episode tomorrow will relate a bit to it.. ultimately the only solution I can see is improving education.. and changing the way we teach.
@@lkrauss1 Could you specifically distinguish in what you mean as to improving education? Is it change of education curriculum or change of teaching methodologies? or whatever you opine
@@lkrauss1 Thanks for the response, I have seen many of your talks, you have always tried to spread knowledge (Carl Sagan would be happy I'm sure), I'm certainly appreciative (and all my 6 grown kids are critical thinkers) But I was wondering if what has been happening recently is influencing your views, myself... I'm more worried.
A question about the unified theory of nature. Isn’t it true that if all the forces of nature were unified, i.e. if the world would be governed by only one force, the world would be completely deterministic. And in a world that is completely deterministic, there would be no time? What I mean by saying that there would be no time is something like this. If the world would be completely deterministic, in each instant there would be the whole of eternity, and therefore there would be no time. And since there is time, the world cannot be governed by one force. Does it make sense? Please let me know. Thank you.
@@lkrauss1 Thank you for replying. You wrote: “time would still be a variable in a world in which the forces were unified.. indeed, I am taking time to write this now.” Exactly here is the impossibility - if all the forces are unified it is impossible to take time. If all the forces of nature were unified then time would be a sequence of moments in which each moment is determined by a previous moment, and taking time would be impossible. In other words, there wouldn’t be free will. And to take time free will is necessary. In order to be able to take time, in order to have free will, the world cannot be completely deterministic (unified theory implies a deterministic world). In order to be able to take time, time must be an opening in which free will has home. And this opening which is time has being only because the forces (at least two) of nature are not unified, and this cleft is what gives the openness which is time. I of course am not a scientist and from a scientific point of view, at least at present, what I wrote maybe sounds as nonesens, but I think that it has validity from a philosophical point of view. And I think that at some point science will move in this direction as far as its view of time :)).
Sir I just have a single question in my mind and no one is clearing it to me. Q: If today's experienced universe evolved from Bigbang, if we believe it was a infinite density particle which all of sudden exploded and gave rise to the millions of galaxies.Where was that particle?I believe that was in space and that points space exists b4 Bigbang, which means universe was existing b4 Bigbang. Please make it clear to me/us.
The camera seems to have some issues now and then but that´s not so bad. More annoying is the sound in the background which I would not identify with a (of nature produced) stream but to some kind of man made artefact . Shooting a film surrounded by nature is a luxury, when you keep the mosquitoes away!!!
1. I can explain Dark Energy with classical physics it is so simple that will be a shame for astronomers if it will happen to be true. 2. Dark Matter is: 74% Hydrogen and 24% Helium but this solution is considered wrong because of a prediction of a single theory ignoring the many straight evidence in front of our noses. I can't withstand hearing about this problem. 3. I don't consider Parallel Dimensions an attractive theme because I don't see how it can be tested. 4. I don't question Black Holes but I question singularity, I rather incline to the exotic states of matter. 5. Quantum computer is the thing if it refers to technology at quantum level but without entanglement. 6. I believe that all forces can be unified but not in the expected way. 7. I think it is selfish to think that our universe is the single universe that can ever exist. We already made that mistake few times before.
Your comments about what drives scientists reminded me of a quote from Isaac Asimov: "The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny."
Hi, I hear all the time that quantum computers are using some weird properties of the universe(if I'm right on this). Because of such weirdness I will like to know if you can make a video and explain if there might be an escape from such a quantum computer simulated civilization if they are in fact very advanced.
Thanks sincerely. As a (somewhat) avid science learner, the amount of simple but powerful ideas about science that I feel I gained during this series is something I'd not find anywhere else. Frequently I had to stop your videos and focus to really grasp the real meaning of your words, and I'll be replaying them for a while. I can only think of some feynman bits that make me feel like I grew this much on powerful concepts. We need much more Krauss please. Take care sir!

Sir I want your help on solving a problem made by me and it can in turn solve the mystery of creation I needed to contact you so thought it would be the best way to contact you
Dark matter = glue of the universe. imagine the field between galaxies, the empty space contain the darkmatter and the darkenergy is somerthing like quantum scale in comparation with darkmatter. if you are asking yourself how do i know that, ... is because im damm hot smart
