thanks for these pleasant conversational interviews. They are interesting, informative, and leave me feeling better for having spent time listening. Much appreciated, and yes I'm going to subscribe
40 minutes into a conversation with one of the most famous living physicists, and the only voice I can hear is Larry's. Prof. Krauss, if you can just get over yourself and let your guests speak, your decent podcast will become a great one.
Maybe he’s tryn to show off for his old professor! Many say Larry goat top living physicist!! Maybe it’s gone to his cork (head) qwork. !! Yes he thinks he’s the bad ass. (And perhaps he is??!)
I have a dream to get graduation from one of world class university. But now I am dazzling on economic crisis on my family so I have to go abroad for money. And it's been a dream to meet you scientists in future. Thank you for podcast with Alan. From Himalaya Nepal.
Wonderful comment. I wish you all the luck with your education. I'm sure that your family loves you and will support your goals. I hope that you make all your good dreams come true.
Are Nepali tu ...ooo shaabji kr ... bakchodi nhi ...tujhe 4 words bhi smjh nhi aa skte ...aur tu abroad ghanta jayega...tu Bina visa ke India aayega aur kisi hotel me bartan saaf krega ...😂😂😂
Avi Loeb(Harvard) dismisses Multiverse theory completely. It is just not science. The idea of dual arrow of time is not new. See Feynman, Sidis and others. If concept is correct then Entropy for the universe as a whole is constant. (Entropy of matter part of universe + Entropy antimatter part = C)
I love this interview. In contrast to something you'd see on TV it's unrushed and indepth. You can a chance to really get a complete understanding of everything they cover. Two if the most interesting people on earthj.
I don't think there's anything more fascinating than the idea that the universe is probably infinite. Mind-boggling. Thanks for bringing this brilliant guest, professor Krauss. Greetings from Zagreb, Croatia!
on a personal note - I grew up noticing an short article in the back of just one of my dad's early 1980's college Astronomy texts that mentions Inflation. I can literally turn myh back, look up and find this book - William J. Kauffman's Universe, in 1985. I of course, read Stephen Hawking's "A Brief History of Time" and then Alan Guth's "Inflationary Cosmology" book. I've stuck with inflation through and through.
I wonder if Guth and Penrose ever collaborate cosmic inflation and conformal change of scale theory - I just can't hold back the excitement I had when guth inflation field matches with CMB meaning universe really was atomic sized or whatever and quantum fluctuations are the source of galactic seeds - it well my mind is still blown- and THIS GUY Alan Guth is partly responsible for that discovery. He is so humble. It's exciting to hear him talk when it isn't over my head
Big Bang needs to be modified to allow survival of antimatter in equal quantities to matter by a mechanism called "Alternate Quantum Phase" I wrote a published letter to New Scientist about 15 years ago on this At the time I referred to Backward Time as Anti-Time, because it was intrinsically linked to antimatter. Antimatter thus becomes a prime candidate for Dark Matter, which is mutually repulsive to Matter. My model extends further to incorporate the idea that matter and antimatter are linked in so far as time on the macro scale in our part of the universe runs in the same direction as time at the quantum level in the antimatter part of the universe, and vice versa. This explains why we do not observe time at the quantum level as we do in classical physics. Also we can remove the necessity for the observer in QM on the basis that our perception of time which runs backward at the Quantum Level, causes our macro oriented senses to believe that the observer is affecting the outcome of quantum events.
I love AG's humility and brilliance. I love LK willingness to stream his thoughts with less filter and it leads to interesting discussion! I love them both
I've always liked the flatness problem as more interesting than the monopoles problem. I think it was Heinz Pag3el's "Prefect Symmetry" that explained it best for me.
Great dialogue between 2 great minds in the world of physics, Lawrence asked very pertinent and interesting questions. There is a feeling in the lay community at times I think, that these guys all know each other so well, but that's often untrue. Some people know some people well but know less about others, so it's interesting when this happens. As for Penrose, Extrordinary claims demand Extrordinary evidence it's true but I don't think he's ever claimed it was true, just that there seems to be some evidence of part of it and no one has critiqued his paper. He's just trying to come up with some interesting work I think, even at 90+. And LK knows that even a universe from nothing had to start with laws of some sort, random though they may be. I don't see a huge difference. I thought of all people, he would be tempted to read it, if only to opine on it.
I didn’t know Guth was Jewish, Sean Carrol really is the only physics popularizer who isn’t Jewish (this is an observation and not an anti semitic statement please don’t take it that way) this is an interesting phenomena, perhaps it was Einstein who spurred this. I heard Lenny Susskind say once “Every Jew knows Einstein” When Lawrence or anyone else refers to the antisemitic times of ‘Jew quotas’ I almost can’t imagine it because of how dominant (for lack of a better term) Jewish Americans are in physics. Anyways I enjoyed this conversation and most of the podcasts you have Lawrence, you’ve really gotten better at this over time and I appreciate that. Forward ever forward my friend ! P.S: Hope to see you on The Lex Fridman podcast soon
I have a picture of Al Guths office in MY office. It makes me feel like I have my #$% together. But, deep down, unfortunately I know I'm just playing mind games w myself.
Lawrence; don't you realize that your belief that the universe is flat, and therefore infinite in spatial extent, directly contradicts Inflation, which assumes the universe is finite in spatial extent? Otherwise it makes no sense to model the universe as doubling in size, once or multiple times. As Guth indicates, around 1:18:00, it *appears* flat because it is hugely large, globally spherical in shape.
Since sound never completely disappears it just goes further and further getting thinner and thinner would it be possible that sounds created inside the universe are making it expand after all God's supposedly created everything with the word could it be possible
Thank you for these truly inspirational podcasts. It is fascinating to hear the first hand recollections of some of the movers and shakers of the last 50 years. Not just the scientists (although they are my personal favourites!), but everybody from Stephen Fry, Penn Gillette and Ricky Gervais to the likes of Jordan Peterson. People I am interested in, but more importantly those I am not interested in at all, have all proved to have at least something to say that makes me stop and think. I also want to thank Lawrence in particular. His incisive and well researched questions manage to get so much valuable information out of his subjects, without being either overly aggressive or too soft. A really useful and entertaining way to fill a couple of hours!
I remember reading the story on Inflation in Scientific American in the early '80s when driving the taxi (down under). I was so engrossed by the reading that I found the taking of passengers an annoyance and could not wait to continue to read the theory that blew my mind, I was 21 at the time. What I found most incredible was how Alan Guth was able to work this out as a process so early in their evolution of the Universe. It never left my mind and it proved instrumental in constructing my own detailed theory of the creation mechanism to explain the Higgs formation and subsequent burst of first light followed by matter and the elusive gravity. It also led me to realise that there was no inflation as a process of enlargement but rather an illusion created by density variation of aether (yes I know it does not exist) and light. The conclusion was that the size of the Universe has to be constant throughoutout time and that the process can only take inside a black hole not unlike static electric charges are created. When a theory is correct there are no lose ends, no mysteries, and all that remains is collecting butterflies.
A very nice interview. I met you one time Lawrence, trying to sell you my model of the fractal and that it behaves like the universe. You said publish. Good advice and I am slowly getting there. I am writing up its quantum foundations properties right now and hope to publish that and get some interest. It should, I hope; it does it all! I can show, by experiment, that the fractal behaves exactly as the Hubble-Lemaitre and inflation epoch expansion (and other observations and conjectures). It grows from the Planck size to a size of 1 in 72 iterations. That is fast. Just as fast as the universe is described. I think if we calibrate the fractal iteration to photon light propagation rate it will correspond with inflation expansion. I don't think this will take away from Alan's work as it does not offer causality, just geometry.
Just so you know, when someone tells you to "publish" what they are saying is that what you are saying is gibberish, please go away and quit bothering me. By saying it in this way, the listener is more likely to not get upset, thinking that they CAN get published, and the speaker will then listen to them in full. Glad for those in the public eye that this tactic still works!
Regarding monopoles, first didn't he state that supercooling would smooth out the topological knots, but then the scarcity of monopoles is explained by the rapid expansion making ~1 per horizon. Are these two points related?
If there are many other dimensions and there most certainly are, although most are still theory, that will change the entirety of theoretical physics. How many theories have been proven false? Why does sub atomic physics not even follow theoretical either? "Ask not where ye came from for even the Lord knoweth not"? Also, do you know anyone who understands the math? So how exactly do you prove it or disprove in when an error of .000000000000001 can change it's entire outcome?
Another fascinating interview by Lawrence Krauss. The only part that disturbed me was when he said that Noam Chomsky was his good friend. I threw up on my mouth just a little bit.
I get the feeling that no one, yet, has the chutzpah to invoke a theory involving the intentional interactions of aliens at the zero point of the Universe we observe which caused the "spark" that gave rise to the inflation mechanism. Doing so, properly, might offer the most palatable explanation to unanswered questions like the Horizon Problem and the uniformity of entropy in the first 10 to the -32 seconds or whatever it is. We ought to ask what we might do, in the far future, after our agentic abilities have matured hyperbolically to enable us to determine the right recipe of matter and energy to set off a reaction that would produce a new "universe." I imagine we'll first be able to model the procedure computationally in a computer before we can begin the process of showing the feasibility of seeding a new universe. Say, for example, by taking the right amount of Hydrogen, Helium, and Lithium (give or take the addition of a number of other elements) and introducing an ultra high infusion of energy to cause the sort of conditions we believe were extant in the first instance of the universe we observe. I know this is going to initially be dismissed as some manifestation of magically thinking a way around many conundrums facing the scientific approach to solving these puzzles. However, I think such an approach, which enlarges the space of possibilities (pardon the pun) may open doors to newer modes of thinking about and arriving at workable models to explain the processes involved in the genesis of this universe we perceive.
the way I remember it, I came up with this idea that the dark energy is an inflationary aftershock. But, I've found that Alan Guth has thought of this. Well, until someone proves it . . .
It would come as no surprise to me if it turns out that the interior design of physicists' homes are invariably white walls and ceilings and black furniture..
I just figured it out. If we want to find Aliens: let's fire fusion bombs at every dead moon in the Solar System. They'll see our Solar System Lighting Up like a Christmas Tree in all areas of the EMS. They'll show up and via a GPT5 type system they'll be like: What in the name of Sweet Baby Jesus are you guys doing?
