- What happened to all of the universe's antimatter? Can a particle be its own anti-particle? And how do you build an experiment to find out? In this program, particle physicists reveal their hunt for a neutrino event so rare, it happens to a single atom at most once every 10,000,000,000,000,000,000,000,000 years: far longer than the current age of the universe. If they find it, it could explain no less than the existence of our matter-filled universe.
PARTICIPANTS: Janet Conrad, Andrea Pocar, Lindley Winslow
MODERATOR: Natalie Wolchover

They should have also included one theoretical physicist in the panel. As Janet said, particle physics is progressing due to cyclic nature of experimental and theoretical discoveries. These experimental physicists did not know much about what theoretical physicists are up to.
It was probably intentional
I found Nancy to be a good moderator.
Well done
Nah was awful
@@MargotDobbie come on man
Yay! They finally re-enabled the ability to download these videos!
Massachusetts is showing its glory on this stage!
Stephen Hawking said in his "A brief history of time", 2005 edition, p.111-112, and also in "Nature of Space and Time" 20l0 edition, p.53-59, that an electron moving on a closed loop in an electric field is equivalent to two oppositely charged particles accelerating away from each other in Minkowski space. If you take this literally, not just as an analogy, then there is a natural answer to the question why no anti-matter have ever been found except during particle collision in a cyclotron, and why a particle and its anti-particle so generated are so short-lived.
Before I watch this video.
"Scalable Aether Universe"!
Aether's CW vortex is Matter/Electrons. Aether's CCW vortex is Mass/Positrons. Where these vortices combine into Hyperboloids is Zero Point/absolute zero/"Condensate of Universe"/Neutrino. Neutrinos are oscillating Inertial planes.
The Dirac equation developed by Paul Dirac actually predicted antimatter a year earlier in 1928 since it came out before the discovery of the positron in 1929. Sad to see that detail missed and one directly related to the solutions being thrown away because "they aren't physical" yet they actually were physical other than that I think it was fairly good.
would be nice if it would be possible to make a sequel to this episode, alternatively a sequel about neutrinos.
What phase is the ice in where you place the neutrino detectors? Just ice 1 or is it denser than that?
Why don't I get notified when this is live 😢🙈
The Sky is Blue. What does that tell you? Spirituality exists. I find this has a wonderful tempering effect on the Scientific Data. In my 51 years of searching for Spiritual truths, the only one that I know of that mentions anti-matter is the Bhagavad Gita.
Do we ever get an answer regarding where Fermi mysteriously disappeared to during Winslow’s Enrico Fermi bio that was going to be answered before the rank amateur host interrupted him for no good reason. I’m 25 min in now and nothin so far.
I don’t expect a Brian Greene or Sean Carrol every event, but the person hosting / “guiding” conversations is what I’d expect from a reasonably competent but inexperienced and shy high school student in the debate club...
This is unreal. The video starts with the claim that anti matter was a surprise, not expected at all. On the contrary, it was predicted by Dirac from his famous equation for a relativistic electron - one of the greatest results of the 20th century physics - it required the existence of the anti electron, or positron as we call it. This is the first thing that a student learns in a relativistic quantum mechanics course. Although every experimentalist show know it - I have never met before anyone who did not - it shows that you also need a theorist on such a panel. I for one never fail to speak about the great work of Dirac even in my public talks, since his prediction of anti matter is arguably a beginning of modern elementary particle physics and a glorious example of a surprise that a theory may carry, an analog of say black holes that Einstein theory of gravity predicted.
No one said anything about how neutrinos interact inside the human and animal when breathed in or is this another video?
Despite of exciting video...made my mind wonders far and wider.
If ghosts interact within and outside of our bodies then neutrinos which comes from sun then we can then absorb neutrinos, no?
If yes as in “we do absorb neutrinos...?
Would it explain types of emotions and behaviors of human beings and nature that at times is looked at as violating natural and balanced laws (Serial killers for example). And a fruit tree that produces tomatoes?
Thank you.
due to anti-matter haveing an oppisite charge, would it act differntly to electo-magnatism and would that effect that combonations these molicules can produce?
Weren't Majorana particles discovered in 2018!? Meaning that it is no longer a fact that everything has an antiparticle partner. Shou-Cheng Zhang and a team of scientists working in conjunction with him actually found the Majorana particles (he referred to them as the "Angel particles" because of the lacking antiparticle).
This is like watching _Delicious Dish_ but for Astrophysics. 😁 Good times, good times. 😌😉
I was wondering why it seemed familiar=)
I haven't started the video yet, but I was just over on Janet Conrad's Wiki page and it says she helped with an inexpensive tabletop muon detector? If we had one of these things at every home, we could turn the world into one gigantic muon detector?
🤔🌍Hmmm.....
never knew that the physicist majorana was such an interesting genius...
Watched for 50 minutes and still not quite sure why 10^26 years is the meme. E: I guess neutrino decay in which Fry is his own grandfather, I loved that Futurama episode.
Petition to change the spelling of neutrino to Newchreeno.
this is new moment conserve your energy
3:30 That's a little presumptuous, isn't it? Dirac, anyone...?
I'm stunned that janet didn't know the dirac equation predicted anti matter before it was discovered. I'm also glad to see some folks knew that
Exactly my thoughts ... my words were... 'hang on.... Dirac?'
how do u reverse the process
even if neutrinos are their own anti particle, that doesnt mean they will annihilate.
I'd like to learn more about the C.P. Violation and try to understand why it apparently exists.
Every human being should want that.
Is there much correlation between theory & what the vedas say about anti-matter?
Kick out a electron have chR=13.6*e energy equal to me*c^2/(2*137^2), me=9.109*10^-31 electron's mass, equal to a positron as a hole in negative energy sea ch=2*3.14*A*me*c^2/137(A=5.29*10^-11 Atom's radius) which equal to 299792458*6.626*10^-34/(4*3.14*5.29*10^-11*137)=chR.
Smart people!
Maybe the journey from mater to antimatter can't be seen in liner time & in fact each intersect on that graph represents a particular dimension in our multiverse & the vibration rate is equal to variations in history due to entropy or something
"Where have all the flowers(Antiflowra)gone!"?
each moment
Maybe we live on the matter side of a chart mapping the journey from nuteno 2 antinutrino making the journey from one to another make the each integer representing entire Multiverse
can a loud stadium generate energy
what is the end
Giggling "Valley girls."
Yang Gang 2020!!! The Big Bang was initiated by UBI.
u can u forward or backward in time but cant past this moment
yeah
yes and at the end of all
this is the middle best scenario
What happened to all those good moderators?
Was thinking the same
She came across so timid and unsure from the beginning
Too young
What does she mean about not knowing if a neutrino or anti neutrino was detected based on the lack of magnetic field at detector? I thought neutrinos were, well, neutral, so they wouldn't be affected anyways... @ 20:20
I think it’s because when it interacts with matter, it would produce an electron or a positron depending on wether it’s a neutrino or anti-neutrino.
Thus it’s not the neutrino per se that is detected, but the product of the interaction, which are electrically charged and so detectable with a magnet.
At least that is what I understood of the presentation.
@@spacefreedomfighter1897 It looks like the detector she is part of, IceCube, uses Chernenkov radiation to indirectly detect neutrinos--so that makes sense.
then why we not at that scenario
its been done
they clean up re-balance
is it new memory or old
What's the half life of Xenon124?
Heck yeah! this is the meaning of life, bro!
Why have they cut the interesting parts ?
Cuz they don't want us to know the best shit... I hate it!
Wow, a lot of women in this panel. We all know men outnumber women in STEM fields at least 10-1, so seems like this group may be seeded for politics more than actual scientific value.
Dolemite23554 Wonder if they meant it to be all women but didn't realize Andrea was a man.
@Django Fett LOL the joke went over your head buddy.
energy is finite
good discussion . i likes the vedios of pro. lindley winslow
save power
how u heard of it
The moderator is horrible. Where did they find her?
Byron Goodman they randomly picked her on the street.
how u get alien
the start and this is the end
Are we basically getting better? you know, like over the length of the last seven-thousand years of time? 'Not' 'Duh?' and 'Yes' are the only answers accepted 🧐
need universe and multiverse energy
If Anti-Matter is the opposite of matter it should not be able to be destroyed....
Matter = Energy (E=MC2).....Destroyed is the wrong word. When they say "annihilate", they mean the matter and/or antimatter is converted to energy. In the end, the total amount of matter AND energy is the same, it just changed form. With a big bang !!!
how u learn if its a legend if its not learn
there is finite energy
Please STOP GIGGLING.
Yeah why the heck are they laughing? "He was a fellow Italian... hahahah"
What's up with the science fashion "look" and colors?
I really hope the moderator won’t keep interfering and babystep holding hands through every concept, we all know what the double slit experiment, the standard model, quarks, and the basic principles behind quantum theory.
Yeah in some videos its absolutely dreadful. No one wants to dredge through basic material when they are here for the exciting stuff.
We all know that will happen
Agreed, but they also have to break it down for introductory purposes too. Making it relatable and understandable. Scientific interest cant have a high bar of entry otherwise we get... Well, we get the American south lol
Baby talk for non physicist.
@The Truth of the Matter "Neutrinos, Matter, and Antimatter: The Yin Yang of the Big Bang". Yeah, that's totally a topic for a layman who does not know physics. Typical popcorn stuff. Next on World Science Festival: "Calabi-Yau manifolds in String Theory". Moderator: "And what is a manifold?". Science populariser: "Manifolds are like spaghetti or doughnuts, but multi-dimensional". Layman: "I know -kungfu- String Theory!"
u can fix it reline
u can reset but there is no more reset
but all have to use each field to repair the universe
everything that was is will be exist has existed
start---- how to solve---erase or fix universe
frame
and dream star war cause it an old recall memory
Great topic, unfortunately not the greatest episode whatsoever.
but its finite
We DONT want to listen about basic principles of physics or math. All who watch this channel sick and tired of this primitive explanations. We came here to see new ideas and understand some recent discoveries.
Vladimir, don't forget that in the United States half the population is scientifically illiterate (close to 50% of disbeleive the Theory of Evolution, and The Big Bang Theory, often in lieu of childish, absurd myths). The clearest symptom for the ignorance and gullibility of Americans is seen in the election and support of a corrupt buffoon as their leader. As for me, a humble "scholar of the universe", I have learned valuable new ideas and understanding from this learned panel.
BTW, don't assume that your hyperbole speaks for ALL viewers as you have declared.
John Hunter me two another curious simpleton.
@@jrhunter007 I have to agree with you. It was said from my subjective perspective. It is not interesting for me, but ,probably, could be useful for others.
Who is the "we" to whom you refer? As a n intelligent and interested non-scientist, I appreciate the "primitive" explanations. Perhaps you are not WSF's target audience, but I am sure there are sources and channels which produce material more suited to your more advanced knowledge/technical baseline.
@D.O.A. Thank you, i know, i am subscribed to this channel
i can translate
and fix the universe
Philosophy and theoretical physics are pretty much the same thing
Hihi :)
I feel they all have a childish compulsive urge they are suppressing to put their knees to their chest and kick one leg and foot unto the floor and spin on the chair yelling "weeeeeeeee!"
i am the alpha and omega
The Search For TRUTH
Often we have heard from those who seek to know TRUTH in scientific ways by verifying theory based on rather short-sighted information.
“Where pride is, there also shall be reproach:
but where humility is, there also is wisdom.”
[Proverbs 11:2]
“And whosoever shall exalt himself shall be humbled:
and he that shall humble himself shall be exalted.”
[Matthew 23:12]
The search for TRUTH cannot be ultimately determined by limited information confirming limited theories. As a specie, we humans will never know all there is to know about TRUTH. For as one door opens, we find illumination shining under a multitude of closed doorways each one ready to be opened into the beautiful light of new discoveries and new doorways- a very exciting, never ending process!
Our Creator began our universe, and possibly an uncountable number of other unique universes, within the Infinite Eternal Conscious Bliss of its own BEING. Thus, every form of energy is known by and communicates its unique being with its Creator. All that manifests lives within the infinite awareness of its Creator. All forms of life “swim within” and are totally dependent upon the will and consciousness of the Creator. Our Creator has endowed innumerable life forms with free will to make responsible decisions for which they are held accountable. Each created set of species live within a unique universe governed by unique interwinding laws at various levels of awareness, and each specie will have the opportunity to eventually pass through “the narrow gate” into a very special “mansion” in paradise.
“In my Father’s house there are many mansions.
If not, I would have told you: because I go to prepare a place for you.”
[John 14:2]
The being who says that it is not necessary to have faith in our Creator searches with its head in the quicksand to discover a very limited spectrum of “sandy truth”- missing the limitless vistas of possible discoveries in the world above his/her created quicksand-filled hole.
And so let us bow before our Creator giving Praise, Adoration and Thanks for the unmerited gift of grace- of living awareness that IAM bestows equally upon each one of us. We have but to love our Creator and our neighbours as we are loved unconditionally-treating all with patience, gentleness and kindness!
“Be you therefore perfect, as also your heavenly Father is perfect.”
[Matthew 5:48]
That is our challenge and our destiny- the choice is yours.4
Doug Norkum - this is not a bible study. No place for that blind dogma here. I'm sorry you don't know what science is.
The moderator really needs to work on public speaking lol
is the universe imbalance
paranirvana if it doesnt reset all be erase
matrix
its past though
i am the alpha and the omega
u wanna bet on that
Amazing how limited as observers we are and humble we are not. More specifically, observers limited by the interactions of photons and matter alike who are comically attempting to explain a universe wherein 99% of it is beyond their ability to observe it. Observers who they themselves can't even explain their own origin and existence! If one were to make an attempt to understand how we may appear to the next greater observers above us but still very far beyond our best imaginations we are collectively a 1 legged duck surrounded by a sphere of an infinite Sea!
Very interesting and thanks for the response seems these days intellectual conversation on social media can be very illusive! I would like to point out that for you to have such an awareness and understanding of anything it had to at some point be observed during it's cycle and within it's local environment. Regardless if that either are classified within CM or QM because at the fundamental level all that exists is information. Furthermore, and unfortunately for us its very possible that even mathematics is merely an emergence from another layer of information that's completely unknown, not observable and unimaginable to us. Biological observers and their technological counterparts have limited understanding of their reality. A constraint thats unknown and directly related to how they observe and decode the available information within their reality. More specifically, a reality wherein the observers understanding is merely an illusion masking it's true nature. Which I have labeled The Observers Paradox!
@John T hahaha Heavens amusement.. Good one.. I'm laughing at them and there laughing at me!!!
What if there are very many independent observers who happen to be creative and imaginative and who cross check and review each others work. That's one way to move the boundary of our limitations .
Or, if an anti neutrino is actually dark matter, and it's three colors of non-charged,purely momentous mass. LOL "IAJ"
i have the solution just need cooperation
meet in the middle rebalance
uh. uh .um .uh .uh
memory wipe
I felt that somehow, ancient Chinese have foreseen many of the things today. No matter how the world change, we human will stay almost the same.
Yeah, yeah... It's just Manicheism. Every culture in the entire universe has invented things viewed as all black or all white with no nuances in between.
I don't think I could make out more than 5 words that guy on the panel said. They should have used subtitles for him.
Giggly , childish. Somewhat disappointing.
women..
if u dont correct it all will be eraze
