The Mystery of Empty Space
HTML-код
- Опубликовано: 23 апр 2008
- Get ready to re-think your ideas of reality. Join UCSD physicist Kim Griest as he takes you on a fascinating excursion, addressing some of the massive efforts and tantalizing bits of evidence which suggest that what goes on in empty space determines the properties of the three-dimensional existence we know and love, and discusses how that reality may be but the wiggling of strings from other dimensions.

This is all make believe pseudoscience! - If you want to watch 'real' science which is much easier to understand watch 'TheThunderBoltsProject' The Electric Universe.

I like the way he explains things. He isn't so up in the clouds that he assumes everyone else there understands all the complicated points. With an ability to speak on the subject in a way that one can understand it w/o being a grad student or post-doc. in particle physics, his info comes across to those who need a push to get started and into the realm of more complex areas, such as the kind of lectures that Leonard Susskind delivers. But, to understand Susskind, you have to really be on your toes, or you'll miss something and that one thing you may blink and miss may be the road block which keeps you from "getting" the wider picture Susskind is painting, with eloquent words.
Michael Faraday had little to no formal education. He was essentially self-taught, visiting libraries and institutions and reading as much material of the time as he could, becoming one of the most influential of scientists.
He started out as a bookbinder's apprentice. Later he became Humphry Davy's lab assistant.
Formalized, institutional education is not the only approach to enlightenment.
Paddy Theosophist; Hail fellow theosophist! I think it was Faraday who married his best maths student and she solved most of his maths problems. Kept very quiet apart from some frank letters to collaborators. Don't spose you know how old this lecture is. I'm thinking early 90's..?
What a bliss to listen to this man, physicist, not at all full of himself - but really telling it right out - in plain English. THAT takes a true genius.
Loved it! There is no actor's play here, just a pure genuine physics, presented passionately.

This was an outstanding presentation. I've heard about dark energy for years, and I had no idea what anyone was talking about. This guy talks for 30 min, and I finally understand the general concept. I would gladly listen to every talk he has ever recorded.
Kim Griest is so full of energy, it takes a while before you realise that every broken sentence he utters is full of fascinating information. He's talking so fast, as if he expects to be shot at any moment. He exudes the meaning of 'mind blowing'. He's so full of conviction and energy he could boil off into the 'ether' before your very eyes. But, I've yet to see someone else explain a fraction of what Kim blurts out. He's a true example of a 'mad' scientist; yet it's clear he believes every word. My take is, he's right.
People like Kim Griest are moved by a passionate heart! It is a pleaser yo attend his lectures.
Is anyone else a little creeped out by the off center, unblinking, stare of the chappie at the very beginning? My eyes are watering in sympathy, and yet I dare not blink and take my eyes off of him for a moment; there is a confidence in that sinister spectacle that tells one that the barrier presented by the screen are held in pitiable contempt by whatever amphibian like alien race he belongs to
This guy is absolutely brilliant at putting complex ideas into simple English.
I agree... but public speakers of excellence should minimize the number of "OK"s in a lecture. Drives me nuts.
User58747 yup. The best explanation of the higgs boson ive heard to-date.
He is a brilliant scientist that can also communicate with sufficiency. The numeber of "OKs" are not the matter here
KurtB oh ok
Kurt.....Next you'll be wanting flowers on your grave...
I have watched this video for over a Dacade now, can’t get tired of it.
I really appreciate this video. The presenters enthusiasm levels are stratospheric.
Kim Griest is one of the highest level speakers i can understand. Awesome talk!

Just found this channel. This guy is great. He really wants you to understand this.
If only he would have been more "exact" about the Belgian theoretical physicists Englert and Brout... I think this guy is great, in some sense (I've listened to way greater people, like Nima Arkani Hamed :)

Galaxia "Belgium is weak."is a satire on a Seinfeld line"Ukraine is weak!"Inside joke if you've never seen the show.Belgium is a fine country.
I finally understand string theory and the Higgs boson field. I also finally understand that there remains another field to discover. Really good, solid, explanations here.
No you don't. You just don't understand it well enough to understand that you don't understand it.
You can't say you understand it if you don't understand the math. Sorry, but that's physics... It's not a verbal subject, it's a mathematical one.
zz0mfgz
Bravo!! Mathematicians can say smething about physics. Mainsream is physics it has SOME USE and much money....
zz0mfgz And you don't understand it well enough that you can tell someone else they don't. Interesting. Math or not, reality must, by definition, be understandable without math. Isn't that a bitch?
I do computer animation. Recently some computer animators applied some serious math to create that black hole for the film "interstellar." They were not Einstein level math people, but they are able to use his math in a practical way. Same here. Give me the concept in a way I can understand like physics, then give me the formulas. I can run with it.
the reason that emptiness is mystery is because of the limitation of our language.,emptiness is not really empty, we calls it empty because we dont know what it is, i know this may looks far fetch but nothing is actually something, it is our language and knowledge that fails to describe these entities in details. in other words we are confusing ourself with the limitations in our language and knowledge.
***** " _Just because we have a word called "nothing" doesn't mean that nothing actually exists_. "
There is nothing, no pun intended, in physics that prevent a nothing from "existing".
jomen112 we means we, our means our and it doesn't means anything more than that. is this difficult to understand?
So now we should have a new word for space with zero energy, in real empty there is no distance by the way
jomen112 "There is nothing, no pun intended, in physics that prevent a nothing from "existing"." An approximate or average nothing can exist, but not an exact nothing (bcs of uncertainty principle).
The quote from Faraday is incomplete. When asked about the utility of electricity, Faraday told Gladstone that one day he would probably be able to tax it
Yeah, I thought the quote lacked something.

He is communicating his thoughts so well here. Beautiful
The way he teach things is incredible .he really wants us to understand things.
Fall in love with this guy want to meet Kim , can do anything if it was possible
I like this kind of top-down lecture. It starts with giving an overview..a good one. I can now make sense of some of the minutiae, the details, and the particulars of particle physics.
Conversely, most lecturers start with the detail and particulars....which don't serve so well in gaining an understanding of the big picture. At least to my mind.
VERY good lecture!
He is used to teaching. When he says, "okay" he is looking at people's faces for understanding, or confusion. Let people teach.

Could The Higgs field
Be Considered to be A part of Time & vacuum.
Could a process of symmetry forming and breaking form the potential for the disorganization of entropy that we have in the Second Law of Thermodynamics with the potential for ever greater symmetry formation that we see in the diversity and complexity of cell life? With a process that is relative to the atoms of the periodic table with a phase change of matter in the from high energy plasma. But the geometry of the process has remained the same; this can be seen with cellular structure at the largest scale of the Universe with galaxies forming where these structure come in contact. And at the smallest scale we have the quantum foam with a similar cellular structure. Both processes can be thought of as a process of spherical symmetry forming and breaking.
And the circle is complete. The Higgs field is science discovering the ancient philosophical conception of Ether. As some say : there is nothing new under the sky.

Bob Miller PLS WATCH MY COMMENT FROM ABOVE!!!
Best description of the Higg's Field I've ever heard.
When they claimed they found the Higgs boson a few years ago I remember there graphs showing a peak at an energy that they claimed was the Higgs but I never knew why they thought that? Why not think it was something else. Was the result model dependent?
I don't understand how some people cant understand that all branches of science are unified by one universe and universal plot. There' s one science no matter how unrelated different fields might appear.
Science is a human construct. The Objective Reality they attempt to describe is "unified".
Why not higgs field gives mass to photons?
The Higgs field can't see the Photons
could you shed some light on that ?
The Higgs field doesn't interact with everything and not all mass comes from Higgs interactions. As far as I know it's mainly electrons.
Every person should see this
stunning video. Wealth of information . Excellent.
Imagine having this man as your neighbor. Barbeque 🍺🍖 and listen to his random thoughts.
Continueing my comment. This guy is on a mission or something. Trying to keep up with the speed of light. Learning people of this complex subject. And hus brilliant. Tanks! Will see it a third time. Well worth the time.
Theoretical mathematicians stopped asking long ago if their discoveries would ever be of use outside mathematics. By the way, nice talk. Fortunately, since this talk we know now Higgs Bosons are real.
Crazy how science works~

Re: David Jeffrey Spetch
Since you have disabled replies, I'll address some of the confusion that abounds in your amusing post, here. Some of it stems from the analogy of the Higgs being a resistive media, or because you are not familiar with basic facts about nature. In any case it is silly to label things you do not understand silly.
The Higgs is not a resistive media (it does not stop moving things), it's a field that exists in all space, no matter if it is empty or not. Not every particle interacts with it, only those that do acquire mass. Photons move at the speed of light because they do not interact with the Higgs.
Like it or not the big bang did occur, there is evidence all around. The Higgs was turned on as a result of spontaneous symmetry breaking. As the universe expanded and cooled down the energy density reached a certain threshold causing it. THink of it as a ball standing on top of another ball in the gravity of the earth - the state is symmetric but not stable, the upper ball spontaneously falls to one side breaking the symmetry (because the ground state is not symmetric). It is a mathematical analogy, don't take it literally.
The universe is expanding, as opposed to matter moving in existing space, in fact due to the expansion some parts of it move faster than the speed of light relative to others, which is impossible for objects moving in space. It does not expand into anything - it is actually easier to grasp than imagining infinite space, there are no infinities in nature. "Theory" is just a word, don't make any assumptions from it, classical mechanics and electrodynamics are also theories, and the whole technical revolution is based on them.
"looking out in space is looking back in time" is not a theory but a simple fact resulting from the finite speed of light. Sun rays don't take time to reach the earth (in their reference frame), for them the distance to earth (or to anywhere) is 0 - it's called Lorentz contraction. That's what relativity is about, it's a property of space-time - when you move faster the space for you shrinks relative to a "stationary" observer, while for him the time for you ticks slower. GPS would not work if relativity of time was not taken into account, so belive it or not, you are probably using that theory.
Supernovae are being observed every day, is there anything in science that that you believe in? lol. Planets have not been stars because they do not have enough mass to start the nuclear reaction in their cores, and planets like earth do not even have enough mass to retain the hydrogen necessary for nuclear reaction. In thermonuclear bombs the fusion reaction is triggered not by gravity compression but artificially with a fission bomb.
The Higgs by the way was found about a year ago. According to the theory predictions.
The string theory is still not proved, as was clearly noted by the speaker. It is at this point a speculation. What is worse - it may never be proved directly, meaning that if another theory emerges that describes the world equally well, there would be no experimental way to determine which (if any) is actually happening.
In conclusion, your largest problem is not that "people are disillusioned to think these mere theories are actually fact..." but your ignorance on the subject. It's good that you have the curiosity though.

really a good nutshell , bravo Kim
how can a string theory be applied and explained in universe while I aint seen any string in universe, yet I do catch on to what a string theor is. So help me with this. T
"this is weird but it's true" - I just love physics!
I am not normally a „nit picker“ but I feel compelled to comment on the glaring error in the graphic at 3:30... The block of ice is broken into water molecules that are represented as two larger oxygen atoms bound with a singular smaller hydrogen atom: O2H ?! Instead of H2O. How could this go unnoticed?
Cuz its a screen play bro. Its bolshit. Water isnt h2o go find out for yourself. You added a catalyst. The salt is whats breaking down not the fuckin water. DERP
Dated lecture but very informative and beautifully simplified

A great job. A splendid lesson, exposition of contents and explanation. Thanks for sharing so much, UCtelevison.
Terrific lecture. Thanks,
I wish they put a photo of my ex’s brain to hammer home the idea of empty space.
This comment is egregiously underrated
I have a theory. Without the Higgs field, all particles would not just travel at speed c but at infinite speed. Not only massless particles like photons but everything. Could it be that the Higgs field does impact photons after all?
Interesting concept and i wonder what would happen. Moving at the speed of light means time has come to a hold. Photons don't decay because there is no time for it to decay. Moving faster would theoretically mean they would move back in time?
Maybe this determination is caused by the Higgs field?
Guy De Vos
But a photon is massless...it is not affected by the Higgs field...maybe only space itself can move faster...
i like it

Funniest comment I read so far! The thing is, you are right about this:)
He speaks to fast and maybe to advanced for ordinary people, many won't understand and loose interest.
I find him more interesting and he does not speak to people as they were school children
No shit.

@Castlegrad No, they're too far down the shitter to come back. Welcome to subject status- you could have been citizens if you hadn't bought into that "dole" notion...
And they call Mystics crazy...
Sheeeesh
It may be crazy but it’s also experimentally verified…
You personally have verified the experiments? Hmmm. Interesting. I once heard from a wise dude that the simpler explanation is almost always the right one.
How the fuck they expect the universe to reveal all its secrets by smashing shyt??? Sounds very childish to me
Great lecture.. the best i have seen so far in this subject..
Are there any ways to test for negative energy density fields?
Ok mr stringman, tell me, what are those ''very small'' strings made of ? What is the mechanism which decides the specific dimensions of the various strings and if there is such a mechanism, how do those strings, whatever they're made of, keep a constant length as to maintain a consistent particle ?
String theory just has too many 'holes' in it if you get my point. I'm an armchair physicist but I can tell that this just doesnt cut it. Please stop wasting time speculating about wild fantasies and work on answering the simple questions. What is energy made of? If 'empty space' is kept from co collapsing onto itself by 'stuff', and nonetheless its actually expanding, what is it expanding into? What is beyond the border of spacial expansion? What are we expanding into ? Nothing? What is nothing ? Where is it and what is it made of? Where is our universe? Nowhere? In the middle of nowhere ? Just how far can we go in one direction ? Forever ? What is the universe contained in and what is that made of and how and why? What is a magnetic field made of? What is a force? Answer the simple questions before you go on a wild-goose chase and may we all sleep better tonight.
I don't know if string theory is correct, but there are indications that it is on the right track. I refer you to Brian Greene's books. But whether it is the correct answer or not, it is a good question to pursue and not just abandon as you would suggest. As for you questions such as "what is space expanding into" and " What is beyond the border of spacial expansion" , I suspect that you are either very limited in your exposure to cosmological theory or have some other agenda (I might suspect a religious agenda but based on your subscriptions, I suspect you are an atheist... good on ya, mate.... Ramen). For starters, have a look at any number of RUclips videos entitles "what is the universe expanding into" and also numerous videos which talk about the "finite universe". Some of your questions are not currently answerable but some (like What is a force?) are very answerable. You might try cracking open a high school or entry level college text book for the answer to that last one.
Good for you. Every question you ask is worth pondering. Knowing the questions, you may be prepared to provide some answers. Please respond here with details of your research.

Hi Martin, to whom are you responding? Alexander or me? I assume it is Alexander.... and I too look forward to seeing his research.
Brammy007a Yes, Alexander. The man with the questions.
Martin Zitter I suspect we will not hear from Alexander. He is one of those people who's brain stops working when confronted with an unknown.
I hate how he presents the idea, okay? I do not know why he talks like that, okay? so they put on the new machine, okay? its irritating! okay? :))
am an old switzerland student in electric Genie orientated in nuclear physics and made my Diploma in nuclear chemie by the PSI (Paul Scherrer Institute) in 1993.
At this time we began to studie Quarks, but we just learn the name of the known new fondamental bricks.
For the first time, i see a documentarie which explain me perfectly how quarks are and much more.
i don't know why a lot of people are saying the same as you like
"I hate how he presents the idea, okay? I do not know why he talks like that,
okay? so they put on the new machine, okay? its irritating! okay?"
i loved how he explained the subject with simple examples which make me understand the hole subject very clearly
Makes you wonder if he's aware of it. Should view/critique his own videos for things like OK, Uhm, Ah, Right and speech that is so rapid that it sounds manic. Toastmaster experience/practice/feedback would help most public speakers. Mastery of the subject matter is a good thing of course, but it's not enough to prevent his OK's from becoming really annoying after a very short while.
Bryan Dempsey I watched the video a second time an i must agree with all : YES, YOU WERE ALL RIGHT WITH HIS NO ENDING "OK" during his complete presentation., but I was so fascinated from his explkication which gave me answer to a huge of things i
Nic mémé The ideea is great! only the okay is irritating (reminds me of southpark m'kay?) (:
azi nuamid He should count how many "ok's" per hour he told through his presentation, maybe he will discover a new theorician physicist constant called "Griest Constant" giving the amount of time wasted with compulsives words per hour. DON'T FORGET THE EXPRESSION "Time is Money", it could help for example to estimate how much money is wasted in the world each year caused by these human compulsive words... (LOL)
It was a very relaxing discussion which gave me power for a good working evenning
great... thank you
It's cool to hear about this stuff from over 5 years ago now that the Higgs boson has been confirmed. I still don't really know what all this stuff means, but it's fun to listen to.
I think ever since Einstein has happened to humanity, theoretical physicists have lost it. They are going stupid and stupid day by day.
You do realise they've found the higgs-boson by now, don't you?
If I take a mic out and scream x=90, some random combination on imagination, physics and mathematics can prove me right. But do you believe x=90 is wrong? or is it right? If you think its right then give me the answer, why? if not, I will prove you how x=90.
***** That's true... I am not a big fan of doing that.
I got that from what stand point you are making this statement ..... good thing is these post Einstein murmurs last till new one to come soon ... actually I'm personally not happy still hanging around to understand what Einstein put into theory 100 yrs ago...
really great lecture, I've ofc heard and read about string theory (mostly from RUclips videos :)) and how there must be 10 or even 11 dimensions for it to make sense etc. But this video helped me to actually understand, or at least to make me think that I now understand a little bit of the actual thinking behind those esoteric theories, so thank you for that.
Often these lectures are presentations to folks already in the know. This one is for the rest of us. Bravo. If the info is going to be shared on youtube this is how it is done. Otherwise leave it for Science and Nature. JMO
This video deserves to get more views.
great informative attention holding lesson
oh we are not figuring out we are remembering - well done
Pico seconds after the big bang the Higgs field "turned on". How fantastic!! This sounds like an apologetic to me!
WOW
It makes me wonder how useful such 'knowledge' rally is to anyone? Seriously, why would anyone with both feet firmly on the ground want to know what happened Pico seconds after the 'big bang'. I am not against spending money on scientific research. But in this case I think that certain people have their priorities screwed up regarding what really needs to be done to advance our Earth civilization.
Still way over my head, but the very best explanation I have come across. Totally interesting. OK ?
A great presenter, It's surprising we don't see him more! He would do a great job communicating science to the world
I enjoyed the presentation. Peter Higgs was awarded the Nobel prize since the Hadron Collider detected the Boson. Thanks for the video.
does anyone know the title of the intro music?
Is the higgs field the fabric of space-time it self or should it be thought more as a function of space?
one more Q - in space objacts are not slowing down. with the higgs field dont they need new energy for not slowing or is it working only on the particals and not slowing the matiryal itself?
this is wonderful thankyou so very very much for this

Completely edifying! August 28, 2018.
Spot on, I have not been able to grasp this theory previously. This is indeed the best introduction I have seen so far into Higgs fields etc. I am reading a lot of hate and anger in the comments. Keep in mind that even if this is wrong, its only going to lead to more research. Profit or no profit, mankind will strive for this knowledge as knowledge is power and power might keep you on the mortal coil for another year/hour/second (which is a priority for most of us!)
Clear and thorough presentation. I like to have 2013 interpretation by Professor Griest
Excellent finally some sensibility . Refreshing . Thanks .
Excellent lecture!
"All of the energy and matter that existed still exists. Matter does not create energy of itself. The actions of matter enable energy to become manifest".
Brilliant!!! the key I think is the extra dimensions they are parallel to the others
Really enjoyed that. Some excellent things learned. Thanks to him.
BRAVO! Wonderful presentation that really brings the universe into perspective.
At 8.45 he say according to higgs field theory everything is massless then again says havy materials slows down in higgs field.. These two sentences seems contradictory.. Can anybody explain please?
This guy is amazingly god teacher...it really helped me to understand some things...great :)
good lecture and a perfect anecdote to end it
grate lecture thx very much for it !!!
What a terrific lecture- very interesting and a great, enthusiastic speaker..
if the higs exists, then would it be present in outher dimentions, in a diffrent phase or types of higs. and also if so arnt we looking for a thing that could be in a outher dimentions but affects this dimention
This is excellent
Best definition of the Higgs field I've heard. Kudos
Thanks so much!!! Great explained!!!
Has discovering the Higgs boson shed any light on what quarks are, i.e. why they have to combined in three.
Awesome presentation! Only wished that in the Q&A at the end, someone had asked where consciousness fits in. Great vid tho, thx.
So I want to know is how and even if anti gravity would work where there is no gravity to react against?
Great presentation for 2008, prophetic in e way.
Does the Higgs field interact differently with matter than anti-matter? It would seem at some point in the history of the universe it did and maybe still does as the two pop in and out of existence with a slight preference for matter to persist.
Also note at the end he mentions the existence of the Higgs field is energy dependent in that it did not exist in the first high energy pico-second. An interesting quality.
Lecture delivered 13 years back, seen it today ....its simplest way I could absorb than others ....the dark energy
wow....this guy is is....amazing..
Kim was a smart man.It is sad that he is gone.He contributed some many great knowledge to the field of physics.
