I'm one of the few people that had the privilege of attending this magical wonderful event! All the lecturers were absolutely brilliant and to my pleasant surprise extremely humble. Dear Lawrence, I will forever be grateful to you for signing your book to my 10 year old son Sergei!

Time is an illusion. Lunch time, doubly so. Thank you, D.A.

One of my favourite intellectuals🇿🇦Thank you for enlightening us !

Your work in spreading knowledge, reason, and wonder make you a true hero of the people. Thank you.

Hi Lawrence. I'm listening to your podcast on Spotify, but I thought I would come over here so I can just say thank you. Thank you so much. The fact that I, a 42 year old roofer in New Zealand can listen to yourself, and all the amazing people you have on your podcast, and hear all these amazing conversations... Words fail me. I'm so grateful. Thank you.

Every time I listen to Lawrence I come away knowing something new. That is the essence of great teaching.

He's a great comedian.

Beautiful! I'm always in awe by your lectures.

Great Exponent and Brilliant discourse about the Unknowns and Knowns of the Universe by Mr Lawrence...Really Enlightening...

Congratulations on your new book

Every lecture by Lawrence Krauss is an absolute gift. I listen to the same lectures many times in a vain effort to better glimpse the range and dimensions of his understanding. I'd love to one day be able to come see him in person, perhaps even shake his hand in gratitude for shining light into areas of my earthly experience which would otherwise have remained unknown. Lets hope he tours Europe soon.

Legend in the making! Thank you Lawrence for sharing your insights and knowledge. Your a great public communicator of science and i hope you have inspired the younger theoretical physicists and scientists from all areas to follow in your foot steps. We dont get much time, let nothing we do be in vain.

The internet is amazing if used correctly at its best, I often listen to some of the smartest, experts like Lawrence talk about cutting edge subjects 9n their fields and it's a total privilege to be able to do that. It wasn't too long ago that to here these people speak it would take you getting into a top university or travelling a long way to hear such minds, I'm truly thankful To hear experts give public lectures and talk candidly about their subject, it's just great.

Wow! As someone who wants to become a Quantum Physicsist, this lecture was truly amazing! I can't wait to read the book! Thank you, Professor Krauss! What a lecture it was!

Just bought this book after seeing this wonderful talk by Prof. Lawrence Krauss. Thank you very much! :-)

Excellent lecture. Very easy to follow, but also covers so many important subjects.

I am soooo glad that you are back giving wonderful lectures to the world!!!

Brilliant as usual 💞

I have actually been thinking "But aren't we just a product of the Universe? We are fine tuned to it not the other way around right?" for many years. Thank you for the eloquent explanation!

Love this project.

What a great talk! Loved it.

Great Lecture, the world needs more!

I have missed you Lawrence. Thank you thank you thank you.

🥳 Ooohh, new lecture from Prof. Krauss?! his spherical cow spiel is amongst my faaavorites.

One of my favourite demonstrations to explain how a constant speed of light can cause two observers to see things in a different order, that is really easy to understand is this: You get two people to stand an equal distance from you, but have them stood so they are 90 degrees apart if you are at the centre of a circle. You represent the centre of the galaxy, you hold two balls representing stars. You then hold your arms out pointing at each person, then drop the two balls at the same time representing them going Supernova. You then ask them, from their perspective which ball would have gone supernova first. Obviously, it would be the one you were holding out towards them. Despite both going supernova at the same time, over such great distances, the speed of light makes time very subjective.

One of my most favourite Professors in the World. Professor Krauss

The order of causality never changes. If event A is causally linked to event B, then B will always follow A, regardless.

This man is a treasure.

They don't build 'em like Lawrence Krauss no more, we need to clone him ;)) beautiful evenrt speech sir, keep it up, looking forward for your future ventures.

Brilliant man!

Thanks!

I began my physics studies at UCLA in 1964 with "texts' being Feynman's Lectures in Physics delivered when he was at CalTech. Within 3 yrs, I was simulating the ammonia molecule's Schrodinger's Equations, Fortran programming it's computations. I was working on terminals next to early speech synthesizing and biomechanial models. Upstairs they were testing the first nuclear magnetic resonators used in today's MRI. Most of what's changed since then is that Americans get MBA and medical degrees, not in the physical sciences or even economics anymore. We live off our past achievements and foreign students in our grad programs.

Good program

I'm incredibly grateful to both of my parents for modelling to me that it's not at all a big deal to not know something, and actually a far bigger deal to pretend to know something when you don't, especially the things no one has the answer to.

Lawrence Krauss is such a pleasure to listen to. I love his "I don't know" attitude, just like feynman had. Only zealots think they know all. Good scientists are very well aware they don't know a lot.

You are by far the person I quote the most , so much information that is so enlightening and still manage to continue delivering new and exciting perspectives and theories. ( I also quote Harris, Dawkins, Dennet , ok sometimes Tyson) . Can't wait to read the new book! Please keep doing this, you have a lot of people who still need to be enlightened. Thanks for all you do!

Dr. Krauss, you are an amazing thinker and an inspiration to the world. The wonder of science is that everything has not been answered yet. As Newton put it, he was just collecting some pebbles on the shore when an entire ocean of knowledge had yet to be explored.

Rumsfeld was summarizing a theory known as 'The Johari Window,. It is a framework for understanding conscious and unconscious bias that can help increase self-awareness and understanding of others. It was created by psychologists Joseph Luft and Harrington Ingham in 1955. The model is named by combining their first names. It consists of four ' window panes' 1. Things we all know 2. Things we know and no one else knows 3. Things we know we don't know 4. Things no one knows.

Love it! This is GREAT STUFF!

12:20 Amplitudehedron perhaps as well can be used in the projection, the shadow of the 3d shape.

So many things everywhere!

Very interesting , and we'll delivered.........certainly a lot to think about and question, ... Which I guess is the whole idea. Keep asking the question to gain a greater knowledge.

2 / 2 I received my first wireless remote clicker for my PowerPoint presentations as far back as 2002. Might I suggest providing one for your guest speakers? This would save them the trouble of repeatedly asking to advance to the next slide. After all, with the advances in AGI these days, such accommodations should be relatively easy to implement.

Gret lecture as usual from L Krauss. Challenging topic!! Pity we couldn't see the images properly due to poor camera work and stray light on the screen as Prof Krauss complained at the start.

'There are known knowns, unknown knowns and unknown unknowns. Who was I giving orders to on 9/11?' Don Rumsfeld

One of the most inspiring talks ive heard. thank you.

You're brilliant as you ever were Sir Krauss!

the latest PBS Nova episodes with heather berlin also covered some of this.(S50, E9 and 10) Definitely worth a watch

OK LK, I am working on it.

This is the right thing to do study this holy book they say i myself had a crushed faith when i study it

Yes Lawrence Krauss! We should learn by formulating good questions not by learning prefabricated answers. By the way I didn't understand why time is not universal ?!...however I am convinced that the main caracteristique of the concept of time is irreversible since I have lost my parents forever and never again, because they have been died

19:08 secs, what happens when the membrane of the lightcone is fractal in covering, i.e. fractal dimensionality.

Loved it! ❤ But here's a further suggestion. Perhaps you can do a shorter version of it in a studio environment by speaking more quietly and clicking to the slides as and when you needed them. Best wishes from a fan❤

@8:21 Kraus says that for distant observers, distant events can happen in different orders. Hence, is there any example where the cause and effect universal phenomenon can be broken? Now that would be interesting... 🤔

universe is timeless

if intelligent life is eternally recurrent, then it means that its most likely related to understanding and answering certain question in kosmos building.

An ideological bases is also intuitive. This includes a scientific intuition used in physics. There the is idea that there might be something beyond writing and words is philosophically valid.

This was good

Great talk. We know very little and our intuition leads us in disparate directions. Luckily there are such people who enjoy banging their minds against the unknown. Thanks, Professor Kraus.

Thorouhly interesting point about protozoa and neurons. It certainly got me thinking. Bertrand Russell was quite a thinker, and the right kind of atheist.

Nothing can come from something 👍

“Time is an illusion. Lunchtime doubly so.”

That's an awesome first slide. Love being mesmerized by traveling along fields as well as magnets, not to mention always being fascinated with UFO'S...not to mention the force, since I chose to walk the path of a Djedi when I was young, at the age of a child, told others I know it's true, nobody believed me, n perhaps that's why they weren't able to tap into their abilities like I was. Perhaps tapping into what was really going on, reason that I had that an extra sensory ability, such as the tingle from Spiderman...and used it to help others and do my best not to take advantage of it in a harmful way

My thinking is that if you can travel through time. We would be stuck only being able to go forward as with the arrow of time. This could be nature's way of preventing paradox.

I was on a Swiss train and there was an announcement, in multiple languages, apologizing for running _two minutes_ late. In most countries you wouldn't even notice.

You don't need to follow anybody. You are all different. (Yes, we are all different)

"Time is an illusion, at lunchtime doubly so"

Lawrence's talks are always pleasant the listen to. It struck me as strange He rightly laughs at the religious myths but then go's on to believe the Swiss train myth both do not stand up to close scrutiny.

12:40 secs perhaps dyson spheres of a sort for the smallest Chandrasekhar types, 3.4 solar masses becomes a diameter of around 3 miles?

There's always been a level of pomposity occupying Krauss's remarks, and he never misses the chance to inject his political opinions into his talks. It' makes listening to him tough.

If i turn a laser pointer on, the beam of light is practically instant. What is at the head of the beam of light? Does the beam of light push particles ahead of it so not only is the beam going at the speed of light but also the particles that are in front of it? Podcasts like this really get me thinking about odd things 😂

Madness

So, Larry, is that where you wrote your monthly Scientific American article? I had a subhscription in 1975 and into 2015, and Sagaa's The Planetary7u Society as well. Something after was weekly Science mag from AAAS too.

Wonder-full

How do we know what the opposers of writing said, if they didn't put it in writing?

♥🖍

Lawrence, tell us more about quintessence. We are a five-bit intelligent life form in a three-bit universe., (Referencing information theory, not relativity)

Podrían subtitular los vídeos , vivimos en América del sur

Time may be an illusion, but it always starts and stops in Greenwich England.

Taking time as an illusion, how can we describe the periodicity of universe?

The known unknowns quote is actually from the Greek philosopher Aristotle. It can be found in the book Nicomachean Ethics.

Love the Indiana Jones look.

Sick 👒

Lawrence K. is a national treasure!

Uncle Krauss:)

*Consciousness* is a singular grammatically. The seeming unity of our consciousness may be us deceiving ourselves and the split brain is some evidence that we have at least two.

31:07 secs. Consciousness can be beyond space as well, and energy. if one takes space, energy, and consciousness to be the fundamental three.

You're correct. The universe, as far as we understand it, doesn't have a purpose or intention to make humans happy. It's a vast and complex system governed by natural laws and processes.

30:25 secs, but what then of intelligent deisgn in the Kosmos. There was an origination to the kosmos itself, and the multiverse. It means that indeed there was intelligent design to the structure of kosmoses, since eventually intelligent life will recognize this aspect of freely given existence... which is recurrent.. possibly.

Most of if the universe may be inhospitable because we were not created to live in most of the universe. There may be other life forms in different parts of the universe. I believe everything is conscious

Time will always be relative because it relies on distance and gravity a universal fact

Consciousness: is the ability to conduct evolutionary (computation) experimentation and learning on oneself. By this definition it can be traced back over the evolutionary tape to its biological origin. (debate on this would take you into the evolutionary computations of human and animal brain).

The way to get these accurate definitions, for getting to the most accurate way of modelling everything, including life, consciousness, etc, is by first understanding how the Grand Unified Theory-Classical Physics was derived, by first being initiated by Hermann Haus and his student in Haus ' post grad courses in electronic engineering at MIT in 1986, Randell Mills. Yes that same Mills, whose company, Brilliant Light and Power is being maligned on Wikipedia. Someone is scared all to hell about what Mills has achieved.

So smart, an atheist, and so nice! Great guy all around, we need more like him!

"Our universe", after the big bang, is a "local place" in Euclidean flat infinite 3+3D spacetime, (ie the state before the big bang, flat, infinite, no matter, no chow flow, no expansion, how else when infinite.). It's the final location that begins-it occurs at the big bang, which is not an explosion, but a change from the previous state to the next, to the plasma state, and that's an ultra-high curvature of 3+3 dimensions of two quantities. It's a boiling vacuum, it's a foam dimensions, i.e. an extremely curved environment; that is, it is a "finite" Universe in an "infinite" flat space-time that "floats" in it. The basic Euclidean network - a grid, 3+3 uncurved dimensions, in the state before the big bang, it is still around us, it exists not only before the big bang, but also after it, it is around us and we and the whole complex universe with matter and galaxies and black holes and gravitational fields, (which are crooked dimensions), we "float" in that flat basic 3+3D network of space-time. The beautiful thing is that even a mathematician will wonder if he doesn't have to explore "how" big is the singularity = "locality-our universe" and will have to recognize the possibility of proposing the reality that in an infinite 3+3D non-curved space-time there are finite localities, arbitrarily large, that is near-infinite and near-zero... Not even mathematicians can determine how large a "unit" is-a unit interval of length or time in an infinite grid grid. That place is "our universe", just one. No nonsense like “multiverses. And the Big Bang was not the creation of the universe "out of nothing" (as string theorists claim), but it was a "jump = jump change of state" from the previous to the next, a "jump" from a completely flat spacetime to a completely curved spacetime.., with extremely curved dimensions , which have been unfolding for 13.8 billion years!!!!, A) They don't expand, but unfold into the global curvature of the "real structure" (The sky full of galaxies and everything we see "floats" the differently curved dimensions of every place we see). B) And simultaneously with the global unpacking, the "local locations" are packed (in the microstructure = in the microworld.) They are packed into matter !!!! They are packed (those dimensions) after the big bang into balls = elementary particles, and these are further packed into conglomerates, i.e. into atoms, molecules, into chemical-biological compounds. Etc, etc...etc, as I have described elsewhere over the years. According to physicists from Di Valentino's team, this anomaly could be explained if the expanding universe had a spherical shape. Which is even the same if the expansion is explained by the "unfolding" of this "initial" curvature of the space-time dimension in the Bang = in a state of arrest in which time begins to pass and expand = the space and time dimensions begin to unfold; this state of space-time of ultra-high curvature of the dimensions of time and length, is a plasma, is a state of foam. In this foam "vacuum boils", on Planck scales it acquires by deformation packing mini-localities = "frozen states" - wave spheres-wave packets that become elementary particles, our human concept, packets that manifest themselves with properties such as mass, spin, charge, etc., etc. (Each particle has a different number of packed dimensions with a different curvature of these; this determines their properties). Then such an initial state of the Universe, the space-time after the Big Bang, unfolds, expands "out" "from the singularity" and still, simultaneously further, collapses, "into itself", into matter. This means that there is a clustering, "combining" of matter elements, such as quarks, leptons, bosons, etc. into even more complex units, into baryons, resonances, then into atoms, then into molecules, into compounds - this is the "packing" of curved dimensions into packages, into more complex conglomerates, and this happens not only after the big bang, but that packaging continues to this day; proteins, DNA... We still have the Planck vacuum around us, "yesterday and today", continuously throughout the history of this! The Universe..,, all around us in the boiling vacuum of the Planck and subplanck scales, the same processes are taking place as they were a million years ago, as they were a billion years ago and 14.24 billion years ago right after the Big Bang. This entire "local universe" with curved dimensions is nested in a 3+3D grid, a grid of flat Euclidean dimensions. The universe "floats" in an infinite flat space-time. And at the same time, since the big bang, there has been (realized) the unfolding=unpacking and packing of dimensions. Both at the same time. What type of curve do we have for global unpacking, I don't know, probably a parabola, I thought about it 35 years ago...; This text was *twice "deformed" by a translation from Czech to English and back again to Czech and then once again to English..., I am very sorry for the complexity of the text, which I no longer feel like correcting

Lawrence looks like one of the Spy v. Spy characters from MAD Magazine in the thumbnail for this vid.

16:42 ... 8 months to Mars and some time there and 6-8 months back wow now that's close to time travel right, on return to earth I'm arriving literally in to the future. And possibly aging less than staying on earth thats if the solar radiation doesn't get me. Great lecture thanks

Time is an illusion, lunch time more than we can ever no.

Well it's 3:33 Pacific Standard time and I'm at 99% battery. Richard Feynman once advocated one mustn't brush their teeth on National television. What did he mean by that? Is it true? I use hot water and I swallow not spit.

There is the time I was watching that and the time you were doing the presentation about the time the story you were telling happened and all at once. Anyone who’d wanna tell me that is not holy smokes would be absolutely cluelessly incorrect
