Harry Cliff is the Science Museum Fellow of Modern Science, which he reckons might be the only job title which begins and ends with ‘science’. He spends half his time searching for signs of new physics at LHCb, one of the four big experiments at CERN’s Large Hadron Collider. For the other half, he indulges his love of talking about physics at the Science Museum, where he develop exhibitions, events and online content.
This Q&A was filmed in the Royal Institution on 31 October 2017.

@20:30 it is mentioned that most of the mass in protons comes from the energy stored in the binding of the strong force. So if mass can result from the storage of energy that implies that mass can result from the release of energy. Could that explain the additional mass mentioned @16:00 where the result is 10^120 too much? Basically, instead of just looking at the mass stored in a cubic metre of space also look at mass generated from energy being released.
If there is a particle for gravity, why is it not destroyed in a black hole? And if it is not destroyed, then, is other particles also intact?
Another question, if they crush a lot of atoms to their basic elements and all those particles are littering the floor underneath the accelerator, if I should then clean up after the scientists by the help of a vaccum cleaner, qould then all those particles automatically re-combine into atoms inside my vacuum cleaner?
He didn't mention the pentaquark, that was a pretty big deal recently.
So we don't know what light , gravity or time really are? I suppose he's really saying that we who live in a physical world can never really understand the sub atomic quantum world ? However he didn't hesitate in answering questions about their properties and relation to each other. There is some irony that we know so much about things we know so little about!
What if time is dark energy, we still have zero understanding of it or why it only seems to flow one direction even though current physics says there is no reason it should be unidirectional.
can you actually call time a dimension, knowing fully well that at any point in the the space co-ordinate is with respect to time. I would rather say dimension in space is as a function of time, not time as a dimension. i stand to be corrected. thanks
Does anyone understand why the graviton wasn't in his standard model diagram of particles?
Harry your my new Johnny Ball I hope you take that as a compliment loved your talk. Do not dumb it down any more keep telling us what we do not know or understand its very inspiring.
Can LHC create and Sustain a black hole the size of a car engine?
I would like to see LHC perpetually controlling the size of a black hole !
Then We can study gravity.
Could the universe be an evaporating black hole?
i have listened to him for hours, and i am so, so dumb
But they forgot the must important question: "How those theories work with the evidence that the Earth is flat?!?"
There is a theory that black holes do not contain a singularity but instead contain a neutron star which is large enough to create an event horizon. The calculation shows that a neutron star would create an event horizon outside its surface at 3.4 solar masses. This theory is consistent with observations of the smallest black hole observed which is 3.8 solar masses.
This explains why the gravitational waves from black holes and neutron stars are so similar. Black holes when they collide do not radiate light because of the event horizon.
So it is not correct to say that the LHC can create black holes because the smallest possible black hole is 3.4 solar masses.

I don’t care if God said so
I am delighted for you if you do.
I am glad to be here. Happy to be alive.
I am eager to argue endlessly with you.
I have no idea what you could possibly say
beyond quoting words and characters
from a supernatural story book.
or telling me your own personal experience.
Please try.
You may convince me of YOUR experience.
Still, I am not you. You are not me.

Very interesting.
Kid at 2:42 sounds like a sad French chef
That kid is at least 3.5x smarter than I.
Harry is and excellent speaker, I hope he can find the time to continue to inform us on these exciting developments.
Space is expanding.Space is creating out of nothing. If the fields for particle exist everywhere. Then that means that this field is creating out of nothing.
Is it like so ?
5:12 excellent question. Kudos to the guts of the person who questioned, especially if he has average science background.
why does the LHC only use hydrogen to smash together ?
That clever child's question "If the theory that gravity leaps through like higher dimensions is true. then that means that there isn't a Boson for gravity so then how could you explain gravity", refers to minute 31 in the main lecture. Go to https://youtu.be/edvdzh9Pggg?t=1894
It is disgraceful to infantilize women to get them to ask a question. We live in a civilized society, no one is afraid to ask a question, get over it.
Wow, this guy can explain Physics in very simple term otherwise it can get very complected.
I do not believe in dark matter. I do, however, believe in planets, dust, black holes, dead stars ect. I do not believe in dark energy. I do, however, believe that it's simply a property of space time to expand as time flows forward.
I really like this guy. Very well spoken, knowledgable, engaging and humble. Really enjoyed the lecture and Q&A.
This lecture is just as simple as magic as an electron. I enjoyed it a lot. Thank You so much Harry Cliff! Super well explain everything. Well done England! Russians are just trash.
Have experiments throughout 2018 given any further insightful results from measuring the Lepton Universality?
MOND CAN explain galaxy rotation curves; however, it cannot explain things like the bullet cluster.
This was a great lecture! It was nice to hear the LHCb lepton universality results being explained to the public.
i dont understand the need for a gravitron. if general relativity is right (and it seams so) gravity is the result of energy distorting space time. the assumption im going to make is the space part of that is the fundamental fields ie the quark field, the electron field ect. if all those fields are biased in the direction of a source of energy why do we need a particle exchange to explain the attraction. also my understanding of the force particles is they work because they dont last very long. if we are exchanging particles with the sun that particles around for 8 min, unless there allowed to break the speed of light for some reason?
'All 3 methods give you broadly similar answers'? What a contradiction of hearsay and conjecture. There is no God, you are just a disposable piece of random energy….
How disappointing it would be to have such high qualifications
in physics and yet not know what time is?
What is the point of it all?
Time is easy, our time began with the big bang because that was when things started to happen, all the events happened one after the other from the creation of stars and galaxies to us, time is not a dimension its a name for events happening one after another, no events no time, simple.
When i hear 'new theories', i get this thought; a person trying to find the best lie to explain something he/she did. lol.
I just had a vision of the Big Bang with all the fundemtal particles/ spaarticles!
I just had a vision of the Big Bang with all the fundemtal particles/ sparticles/ anti all that!
Con job explanations!
A case against Neutron Stars.The following is hypothetical scenario based on known physics, which would explain the Improbability of neutron stars; Neutron is made out of an electron and proton and neutrino, (neutrons are Known to be unstable due to Beta decay) it is a fact that the Neutrinos escapes from the neutrons because of nuclear decay due to the low mass, or close to Zero mass, that is, the neutrinos would be lost or radiated away, it must be emphasized that Neutrino is part of the ingredients of a Neutron. After losing a neutrino what would be left is a proton and a electron, which would constitute the ingredients of a hydrogen atom not a Neutron , being that the Protons Is heavier (by 1800 times) then the Electron, it is quite possible that the interior will become a large Proton like object, but only if there is enough gravity , there for, it should be called a Proton Star and not a Neutron Star. The core would be of pure hydrogen nuclei. Between these two scenarios the most plausible would be Proton star, because it is based on known physics. But, even here, in this scenario the protons couldn't remain together in any high density because of the Coulomb forces, which would prohibit confinements of these protons. Neutron star Scenario just doesn’t make sense ! The fact is that a neutron stars is actually Hypothetical objects and the physics that is suppose to supports this is vague. The Pauli exclusion principle Is introduce because it helps explain the density packing, but there are other forces That will inhibit these high densities ever being achieved. So there is no credible explanations about how the Neutron Star would be kept together. This hypothetical neutron star explanation is one dimensional thinking, which ignores other factors in physics. So don’t be fooled! I challenge any one to dispute this reasoning!
I have question for him and you people:
can we create "artificall matter" , different than dark matter?
the second:
what is the name for "force" that keep universe in one, multidimensional piece?
He slipped up and said the black holes weve created.. and then fixed himself maybe they have already figured it all out n he is only saying a little bit of what they know
Interesting.
OMG, he's so cute!
Damn what a speaker. Is this what is called a good speaker or he has just tremendous knowledge of the subject that hooked me up to the end.
One of the best public speakers in science. I’ve listened to so many but this lecture was very fluid with way he conducted it. ?
It's funny to watch all the people who are bored.
And yet, we are unable to keep our planet clean…….fuck me.
great variety of thoughtful questions from the audience
