The Conway Memorial Lecture 2016 with Lawrence Krauss. Chaired by A. C. Grayling.
This is how the story of the greatest intellectual adventure in history should be introduced - how humanity reached its current understanding of the universe, one that is far removed from the realm of everyday experience. Krauss connects the world we know with the invisible world all around us, which is removed from intuition and direct sensation. He explains our current understanding of nature and the struggle to construct the greatest theoretical edifice ever assembled, the Standard Model of Particle Physics -- and then to understand its implications for our existence.
[This talk was filmed at Conway Hall, London, in 2016]

Conway Hall hosts a wide variety of talks, concerts, exhibitions, courses, performances, community and social events. It is also renowned as a hub for free speech and independent thought, hosting suffragettes, political radicals, scientists, philosophers, artists, performers; campaign, charities and other non-profit organisations.
Who knew that i would be living in the time of new physics Titans and that i would be able to grasp history while its in the making. Real progress observable in our lifetime!
Lawrence Krauss makes me cry of joy for the knowledge and the advancements in science in our life time. This conference is so good that everybody should watch it. He has the ability to make you understand the most difficult theories. Thank so much Lawrence.
Lol he's mainly just regurgitating what's on wikipedia.
It is the worst of times, politics are part of our daily lives. I am glad intelligent people are discussing it.
I wonder what a world without politics would look like.
It has happened countless times in history. In between civilizations...
@Vasian Vasianich Because politics aren´t the way of peace.
Look around you today. All dictators......
Complete chaos
Not so mundane for sure!
The hidden reality theory is one the most interesting idea that has ever existed and I think will ever exist. This is because in hidden reality every thing is possible simply because no one has information to conclude on yes or no. That's why the reality is hidden and so interesting.
Lawrence Krauss is just over the top with his discussion talks, and I wish he did more of them.
The MORE I come to KNOW, The MORE I come to KNOW I "REALLY DONT"KNOW.
@Hector Lian Such a healthy person.. keep it up.
when asked what its like being the smartest person on earth Einstein replied "I don't know ask Mr. Tesla"
A real crime that the Banksters destroyed him financially and sold his Legacy.....Crimes against Humanity are Countless,,,"DELETE THE ELITE! OFF WITH THERE HEADS FRENCH STYLE....😮
He may have just been being snide. Tesla had very openly criticized Einstein's theories.
What role does cold dark plasma have relative to the dark matter, dark energy theory? It is getting imaged now. Electric universe theory seems well after this. SAFIRE project experiments now show fusion and transmutation of all elements, as of 2019, at low power experiments.
@@tmst2199 Well then Einstein got the last laugh. Even if it was posthumously.
@@Amberscion He got to laugh every day that Tesla, the greatest inventor of modern times, was relegated to feeding pigeons in the park and living off welfare.
Great lecture despite The moderators politics. Let’s go Brandon!

They torched to library but it was very little if anything important in there. The info is still around you have to understand the wicked people who stole the info. I tell you this they will never give Ancient Egypt it's credit because the people was their complete opposite and still is to this day. Ever wonder why slavery was so accepted because the world was waiting for the downfall of those people.

@@interstateneek nobody knows anything for sure
@@beavinator420 I suspect that was by design. Who would believe the great Persian King Darius built a suez predecessor via a canal to the Nile around 500BC? It seems much of ancient history is dark more by design than anything else and the would be purveyors of light are still infants rediscovering science our ancestors once mastered.
Everyone on Earth 🌏 needs to stop and watch this now. Brilliant.
Is this the guy that talks about nothing?
Glad I read the comments before 10 minutes in.
Farewell
reading these comments make me so happy knowing people are awakening
Oh...so thats what waking up means? Can't believe how dumb you folks are.
Brilliant? That's definitely debatable. Boring? Absolutely!
Britain is measuring itself for a coffin.
Oh you thought this was supposed to reality TV? Watch Keeping up with the Kardashians....or a replay of the Apprentice. You are on the wrong channel.
I like listening to experts in physics and respect their expertise in the field. What I don't like listening to is when scientists believe they are experts in everything, including politics.
I love the way the staunch materialist Lawrence Krauss very carefully calls it an 'accident' rather than a 'miracle'. Especially when in this case both mean the same thing. As Einstein said: Either you believe it all happened by accident or you believe it was a miracle.
or it was an "accident"
Miracles do'n't exist.
That’s not what Einstein said.
But they don't mean the same thing. Miracle implies attribution to the divine, hence why he wouldn't use that word.
It's only a miracle if you believe this universe is the first and only one. If you believe in a cyclic universe, then there has been endless iterations before us, perhaps all with slightly different physical properties. Endless iterations that for a multitude of reasons perhaps didn't exist for long or folded because the properties of mass reversed or life didn't evolve in them. We only see it as a miracle because this is the only reality we know of.
I was torn between this and "The Great British Bake Off"
I chose wisely.
No contest imo :)
Primus 777 what was the bake off like?
if that's so, Primus. why were you thinking of watching it?
Wow, you're smart!
I'm sure in one reality you chose wrong
His illustration served to make me feel that there are perspectives and personal realities based on our individual perspectives. They’re not really an illusion as such, just a limited view of reality, a definition of reality from our own perspective. That’s why curiosity is so important for science, to get us to m wonder what’s beyond our own horizon.
“The illusion of design is an accident”
This is an atheist fantasy rather than a scientific theory. The danger of taking physics into the realm of philosophy is that we use it to create new religions every day that suit our own fantastic imagination. It tells us something about our inner desires, but sheds very little light on the true nature of reality.
The fact that matter and the universe as we know could blink put of existence in a moment should cause us to be filled with wonder that our existence is so improbable, potentially ephemeral and apparently accidental; that so much order and beauty has arisen out of apparently nothing doesn’t mean to me that life and the universe are meaningless. It means to me that they’re incredibly miraculous and that our existence is providential. It adds meaning to our existence rather than removing it.
Greatly enjoyed this lecture!
This talk is amazing. It is the best Lawrence Krauss talk that I have ever watched. Thanks for sharing it.
if you havent seen his life of physicists one, that one is very good.
Thanks for the suggestion, I will check that talk.
Please give me a summary of what he said.
He explains the development of the modern physics from Faraday, Maxwell, Einstein, to today. Even a non-physicist like me can understand.
drmysteriousx Amazing? Maybe parts. But ultimately it was illogical confused nonsense.
Thanks for informing me... not to bother with that book... it’s funny how I might have been interested until I actually saw this... that would not have been time well wasted! Life is short... spend it with awesome people!!
The lecture is good dont get me wrong, but if you dont know why something is why call it an accident, I'd rather just say its unknown.
can not say it unknown, you are here and also can not call it accident, we all come to ˝an end˝ accident or not - problem is you think you are not conscientous like gods and spooky ghosts, but you are and that is hope for me too, to go do what i will do in next hour
I accidentally skipped over the one slight political comment at very beginning, by moving my thumb to the start of his talk. Just an fyi for those of you who want to avoid politics: easily done, you just have to want to focus on science 👍
Exactly! Thumbs up. This guy is a fail.
A fail for having differing political views from you? It doesn't matter, it doesn't matter if they're the same views, because the rest of it is science. Humans have political views and interests no matter who they are, you may want to start getting over it and focusing on the info you came for. Or don't watch. That's an option too. Amazing thought right?
You start your first sentence bending the truth. Fascinating. Not sure if this style of clever deception is intentional or some type of subconscious conditioning.

Finally! Someone understands the allegory of the cave.
For a theoretical physicist to say that something is impossible.......I shake my head sometimes at such irony.
I find such assertions arrogant in the extreme. And if a scientific lecture can't be made without so many political and religious slams then it can't have much to do with science. I don't find such jabs to be quite as cute as his audience. I'm not really a Trump fanboy, but history has shown that he wasn't nearly as bad as people made him out to be.
If he has good evidence or proof something is impossible...then you must accept it ..there are no married Bachelors
@@rationalsceptic7634 that would not be very scientific!! Sounds like the APPEAL TO AUTHORITY FALLACY.
But, you're right....it would have to be demonstrated.....everywhere. On every planet, on every moon....everywhere.
If what was considered an impossibility here on earth was demonstrated to be possible elsewhere in the universe.....is it still impossible?!
Theoretical physics are still governed by known laws of physics and mathematics. I don't see the problem.
@@SMPKarma
Except Quantum Indeterminacy rules out accessible underlying substratum or hidden variables for God to tweak..all we have are correlations not causation!
I spend hours at a time listening to lectures. I love them when there's something to say...
But this. Damn. I enjoyed him on Rogan years ago.
Thank you Lawrence. Beau...uuuu...tiful lecture!
Krauss is hard to follow but he does bring fresh knowledge to a old subject and there is a need of his thoughts.
The use of drugs enhances consciousness.. and this guy is the best example of that.....
Over promise. Under deliver.
"The universe should be grateful that we are here" sounds like a return to the beliefs that we are the centre of the universe.
consciousness IS, check Tom Campbell - ua-cam.com/users/twcjr44
I don't see it that way. It's not arrogance - we're not special - we're just different because we're so curious.
The universe doesn't need us. It managed perfectly well before we showed up and won't miss us when we're gone.
Krauss's tongue-in-cheek point is that it's never nice to be taken for granted. Unlike the hydrogen, rocks, oceans, daffodils and cockroaches that the universe produced before us, humans are a species that's prepared to compliment it on its new hairstyle and ask it how it's feeling.
It's spent thousands of millions of years producing natural wonders, marvels, horrors and weird phenomena, all of which, as far as we know, have been completely ignored.
How very rude... 🤭
I'm sure the thinking behind that is just so that there is witnessing to everything happening. It's not inferring that we are special, unique, or alone, because in all likelyhood we are none of those. Just as it stands we are the only ones we know of who can document their observations of the reality we are living in.
@@Aeis_Kalt But our observations are limited. It's like saying a comedian should be grateful for a theatre filled with the most miserable people on earth.
The unexamined life might not be worth living, but is the unlived life worth examining?
@@happinesstan Some observation is better than none. Even with our limited scope of vision and interpretation, it's better than to have none of either.
Lawrence is such a great physicist that i always care about his ideas on that. I do not however care about his political views especially that i take it he preferred Hillary.
@GMBCATASTROPHE truth! Good comment
I appreciate you.
I can't speak on behalf of Walter Russell, because I'm not him. However

You set this up as the greatest and best, if this is our greatest and best, at least those that believe that premise are in trouble.
One piece of beauty in words, in fact religious people should enjoy this as well too bad the fight it. here in Europe we think this science story will and has to be the new basis for everything we do. but let's not forget our fantasy, imagination and dreams. I would argue all the philosophy spiritual theories and religions were the best game in town back then and we should not condemn those people but we do have to change the people who still believe these old theories. and with the necessary time and efforts this has to succeed.

"It's really important to understand that we're not seeing reality," says neuroscientist Patrick Cavanagh, a research professor at Dartmouth College and senior research fellow at Glendon College in Canada. "We see a story that is created for us." Further research into reality and the fundamental that is forever,permanence and existential and not that of a 3D non-existential of dimensions of time and space as proven or unproven (yet to be discovered. )
After reading comments here about Kraus and his agenda, I decided this is a must miss.
Personal politics has no place in a science lecture.
Globalists control education. Easy to spot the anti American, anti Christian biased coming from these sellouts.
Laurance Krauss is exitable, but he knows his stuff, he is exitable because of how far we have advanced in the 21st century and want's us all to realise what he can realise.

@Luxury Lowlife EM waves do not need a medium through which to travel. The luminiferous aether was disproven in 1887 by the Michelson-Morley experiment. If you don't understand this, how can you possibly think you understand something as complex as ZPE (which cannot be used for propulsion, as momentum requires interaction between real particles).

I want a person like this to not express any political view. I so want to get away from this lack of true presence. I want information without someone trying to get me to agree with what they believe about politics. So often he is trying to express his narrow views on subjects like education and politics. Put out the information on your topics without any personal views so everyone no matter their political views or religious, life beliefs can get the full benefit and this will truly educate everyone and not just the people who agree with your life views in the so called limited reality that we live in.

“In Canada where they actually educate us.”

Also, the “Cool Principal” look isn’t a good one.
Trust me, Canadian children are indoctrinated and turned into robots who are taught not to think for themselves and, that there are multitudes of human biology, same as any other western society.
He's definitely biased.. which makes everything he says tainted by bias and opinion...I'm out.
First of all, he should know about the education systems here because he IS a teacher, a professor. It is not because of insecurity, but because he is pointing out the truth - that the system really needs to change. Listen to the last 5 or so minutes, his answer to the very last question "What can we do to educate people?" He gives a fantastic answer.
I think his viewpoint and comment tried to point out the deplorable way some countries leaders tefute science. Like about climate change or evolution.
Basically a world view diference. He was wrong to make the comment I agree but, him being an educator I can unnderstand his frustration.

Our existence is no accident. In Fact the universe has eligant design
Well I am having a hard time with the accident of existence. Science knows that tests collapse upon observation. This doesn't take into accountabout our conscious energy. Do we live in a matrix? Absolutely for me one of intelligent design.

@@orattigan I'd like to compile a list of ALL the exactly optimal critical fine-tuning points uncovered within our reality. It's all mind-boggling to Mathematicians who know the total impossibility of even one of these being a pure happenstance. I'm sure taken together they defy any logical fantastic reach for mere probabilities - even if given infinite universes. Our universe is so precisely tuned it proves intelligent design. But we continue to ignore that solid implication while we struggle to find our way back out of the rabbit hole. But we looked in and now it's too late! Pandora's box has been opened; time to man up and get on with it. Millions of years of evolution demand us to accept and reach higher. If we accept what we are learning it will soon be evident that what we do to another we do to ourself! That knowledge proven creates a reality we truly deserve to live.
@@orattigan do you mean a vast waste except 1 teeny tiny planet where 90% of its surface is uninhabitable. Almost everything to eat is poisionous, tastes gross, and fights back, except a few food items that we design.

The chances of that are exactly 1.

Red Shoes and a black eye....🏰Reptilian?
The red shoes are made from the child sacrifice is when they hunt the children in the Black Forest on the Roth Childs property every year you better start doing your research because there’s symbolism is everywhere as long as you know what their symbolism is you’ll know exactly what’s going on. There is an alien race controlling humanity through black magic blood sacrifice. Look up Harold Kautz-Villa’s work on UA-cam, He’s a German scientist who has physical proof connecting the freemasons with black magic blood ritual sacrifice child trafficking black girl and an alien entity that ends up possessing these people eventually through blood sacrifice with the DNA in the blood. I can’t explain it as well as he can but we’re actually fighting an alien invasion through Black Magic rituals and blood sacrifice the Christians call them demons and the Muslims call them Jinn.
Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles
and makes people blind to the underlying errors. The theory is like a beggar clothed in
purple whom ignorant people take for a king.. its exponents are brilliant men but they are metaphysicists rather than scientists.
Nikola Tesla
Nikola Tesla would've been the type of person who would've immediately discredited Michael Faraday out of ignorance regarding of the manner Faraday operated.
Einstein's theory lines up with a lot of esoteric knowledge so I trust he's not too far off with his claims. Considering how his theory has lined up with all the recent discoveries regarding black holes I'd say it's safe to say Tesla was out of his league with this. Science is nowhere near close to explaining all of the non-physical aspects of this universe, so applying metaphysics, or philosophical ideas based on empirical observations, to something like gravity is the next best thing one could do.
@@RSColor so gravity has been tested and proven? Not being a smartass. I've read it hadn't been. Just asking.

"For ALL things were created;things in heaven and on EARTH,VISIBLE and INVISIBLE....He is BEFORE ALL things,and in Him ALL things HOLD together Colossians 1:16-17
+Last 2 - when you don't have a brain, it's unlikely you'll ever get the point. Get the point?
The point is that so many of the discoveries made in the field of physics would sound like mythical stories if they were not demonstrably true. Krauss is arguing that while many people consider science to be boring, scientific explanations of the universe are actually more fascinating than the religious explanations that many of us cling to. That's his thesis anyway. The rest of the lecture serves as evidence/examples of interesting scientific discoveries throughout history that prove his thesis.
Awesome mr. Krauss your a living legend . It’s too bad not many people understand physics
He doesn't understand much else he's a liberal Democrat that proves he's an idiot
Yeah they educated you but took all your common sense and intelligence
"The important stuff in the universe is not the stuff we can see, it's the stuff we can't see." Interesting metaphor for spirituality, eh?
1:22:11 I just love it when people like this guy start drawing conclusions out of things they don't remotely understand.
"The light speed limit is just bollocks, obviously... because If two objects are on a collision course at 3/4C, then their combined speed must be 1.5C, duh..."
It exemplifies Krauss' icicle analogy/the allegory of the cavern beautifully: thick people have trouble understanding what's not immediately apparent, and they end up denying it.
This guy can only think in Newtonian terms, so he assumes that anything beyond Newtonian physics must be rubbish...because, obviously, if he can't understand something, then NOBODY can, ^^.
It must be sad for him, denying all sorts of stuff just because he can't figure them out... and I bet he still thinks he's a genius, ^^
So we are in a relativistic situation, we have two objects moving at 3/4C towards each other.
First off, we need to specify a frame of reference, we can choose between being inside one of those objects or being an external observer.
An external observer will see the two objects moving at 3/4C towards each other, so there's no mystery there, case closed.
The interesting bit comes when we enter either object's frame of reference. From that perspective, we aren't moving at all (assuming constant speed and direction), it's the rest of the world that's rushing by us at 3/4C.
Now the guy will say "and since the other object is moving 3/4C relative to the external observer, that means that it's 0.75C + 0.75C = 1.5C, duh" Well, nope. The mistake is applying Newtonian physics, just adding together V1+V2 and be done with it.
As Krauss explained, every observer has a twisted space-time perspective, dependant on position and relative speed.
Space contracts/time dilates the faster you go (according to other frames of reference), so it's not as simple as V1+V2 = PV.
It's actually more like (V1 + V2) / 1 + (V1 x V2) = Perceived Velocity (if the other object is moving towards you).
In this particular case:
V1 = 0.75C
V2 = 0.75C
So let's apply the equation and see what's the actual perceived velocity from each object's frame of reference.
(0.75 + 0.75) / 1 + (0.75 x 0.75) = 1.5 / 1.5625 = 0.96C
There you go, less than 1C.
There's more than one way of getting this kind of result, but the fundamentals are the same: space and time contract and dilate, the faster you go, so kiss Newtonian assumptions goodbye, they are only approximations that just don't work at relativistic speeds.
Now you could say that this is just a dishonest equation designed so speeds which should amount to a number greater than 1, end up giving a result smaller than 1. And I would agree with you...except for the fact that equations like this one actually work when put to the test...they actually describe how the physical world behaves, Newtonian equations, on the other hand, fail at relativistic speeds. You can actually use relativistic equations to calculate mundane speeds too, they'll give you even more accurate results than Newtonian equations.
Not Uhhh.

Had to stop watching once he started talking about Trump. Dang it, leave politics aside!
politic are very important to ignore. even u hate politic and does not care. political ruler always affect your everyday life. The ruler of country can dictate you have access to social media or not. pls don't be ignorant.
I felt the same also the studdering didn't help
I got to 13 minutes before turning off !
I just left the same comment basically.
@@websiteanimex I am not an ignorant whatsoever! I love politics and I am very well versed about it. If you noticed, he did not make any remarks worth listening to, but sarcastic ridiculous ones. So... who's the ignorant?
So if the "mistake" that created this new omnipresent field, as suggested in his "living in a superconductor" theory, is currently at a point where it cannot possibly be yet established as to whether this field will stay as it is, reduce/collapse, or grow, then surely one theory must be that it is to grow/evolve and such forces/reactions will then become the norm, rather than an exception to the rule?
Ok now turn it down it’s giving me a headache
Theoretically your shoes reflect the speed of your adoption of nonsense when confronted with dichotomies.
The field can be seen under the right conditions
I was slowly working on creating English subtitles for this video. It seems Conway Hall disabled user contributions like that. Pity!
Look at a star and know it is gone
Yes, all we ever do is live in the past, since we are (in our interactions with material life, aka the world) way slower than light.
But where does the fields come from? Say the electro-magnetic field, for simplicity. Where is it and what does it consist of and when did it start and how?
How much intelligence does it take to understand everything as just "an accident".
Ask your mom
@@nihlify Well played
Well said. Well said.
@@nihlify and how much intelligence does it take to get on UA-cam comments and troll someone's dead mother? Get a life dude and a real job... Sad.
If everything is an accident, then humans have no more worth than say, slime on a wall. The same goes for your ideas!
Not sure how such otherwise intelligent people still believe in politics after events and coverups like JFK, 9/11, etc.

About the Van Gogh painting:That is painted in a style that Van Gogh invented called expressionism. Vincent Van Gogh invented figurative expressionism.
It seems to me that his red shoes tells a horror story for the more discerning.
Omg😢
sure does : O ! and he is not funny either ! Sounds like Kilarys jokes
Well he was mates with Epstein...
Can't watch it now 😳. Red shoes 😢
I'm starting to wonder if prof. Krauss is sponsored by Converse.
The answer is know thyself and all the answers within all of us which is LOVE thy neighbor as you love yourself. Then heaven on earth is manifest in all our HEARTs. Coz we are not outside of us. We are what we make in our higher self., I love you all.
It's sad to be caught in a bubble with no exit.
To make it worse would be to say that no one gets out alive.
Loved the lecture. All I’ll say is on the large hadron collider..... physicists imagined it, but engineers built it. A few props might get kids into the industry. 👍
Rumour has it ..if he clicks his heels together..he'll instantly get home...
Keep your political opinions out of the science
"Peer Review" is a Gatekeeping exercise/
@@xHambone357x It is a lecture about science to scientists, again I say keep your political opinions out of lectures and science like this, unless your lecture is about politics.
@@xHambone357x no it's about science, he tried to make it about politics, which is why is fan base has shrunk significantly in the last 3yrs
Soon as it hit politics, I changed to another video...
