On Friday July 13 at noon, faculty and other members of the Physics Department helped the campus community understand the significance of discovering the Higgs Boson, the particle that was predicted by Peter Higgs almost 50 years ago. Mark Richards, Executive Dean of the College of Letters & Sciences, will host this discussion for the Berkeley community.
Professors Beate Heinemann, an experimental physicist and a member of the ATLAS experiment at the LHC in CERN, Switzerland, and Lawrence Hall, a theoretical physicist and former Director of the Berkeley Center for Theoretical Physics, explained what the Higgs is, why it was predicted and how it was proven to exist. They were joined by panel members Professor Marjorie Shapiro, also a member of the Atlas experiment, Miller Fellow Josh Ruderman and PhD student and ATLAS member Louise Skinnari.

Since they are approaching a quadrillion proton-proton interactions, what would happen if a created super-dense particle started attracting other particles and did not instantly vanish as theorized?

So much fluff on the topic, in this video I learned a small piece of the puzzle. 1:08:49 "...I don't know any physicist who would ever use that name..." Among others, Leon Lederman (1988 Nobel laureate in physics) wrote a book entitled "The God Particle". I have three questions if any body has an idea, please reply-

1.How much radiation is produced at the LHC? Please compare it to an X-ray or near a power plant. 2.They say there have been over 800 Trillion proton-proton interactions at the LHC so far. I am not saying they did not find evidence of a Higgs Boson, but I am asking how can they tell a Higgs Boson from a computer or equipment glitch? 3.If they increase the energy of the LHC in 2014,is there a theoretical chance (even a miniscule chance) of creating a super-dense particle (subatomic black hole)?

@geniusofmozart 11 лет назад

Very interesting how even a discovery paves the way for at least 4 other discoveries and research topics. That's the great thing about science, there are always more questions, though it would be nice to have all of the answers one day. Solving the problem that the theoretical physicist at the start mentioned will be a prominent topic in research facilities in the future, I assume.

@iloveRedVsBlue 11 лет назад

The higgs field produces bosons (which are highly unstable) that decay almost immediately into certain matter particles. Something about the higgs field allows for the transfer of pure energy to 'matter energy'. Also why the boson is sometimes considered the 'God' particle, because its the original particle that creates all other particles.

@iloveRedVsBlue 11 лет назад

I believe that everything that we discover will constantly be another stepping stone and that everything can be infinatley be broken down smaller and smaller. We will still have answers, But we will constantly have more questions as a result.

How and why does the higgs field produce bosons? what causes it to do so? where does the "pure energy" come from? and what form is it in before it turns into 'matter energy'?

In 1980 Gould said, ‘The absence of fossil evidence for intermediary stages between major transitions in organic design, indeed our inability, even in our imagination, to construct functional intermediates in many cases, has been a persistent and nagging problem for gradualistic accounts of evolution.’6

in quantum physics isn't any particle just an observation? I thought the actual act of observation changed the action of the particle? so how can they say that they have observed the particle without considering the observation effect?

Extra dimensions were proposed to make string theory, the best candidate for a theory of quantum gravity, coherent. There's no evidence that they exist and essentially no direct way to detect them. It's hypothesised that the LHC may detect evidence for them, via energy escaping to the extra dimensions at the highest energies. But as of today, we only know of 4 dimensions. PS. Physicists are regular people too :D

@7777Ralph 11 лет назад

There is a built in symbiotic relationship of sorts between the nature of light and the observer, like there is with the higgs field and gravity. What good would gravity be without the higgs field, and vise versa what good would the higgs field be without gravity? When it comes to photons, there is a relationship between the observer and the photon where the nature of the photon changes based on the act of observing. This means we don't even know how a photon works when it's not observed.

@sidewaysfcs0718 11 лет назад

because that explanation is quite obvious, yes all particle are actually massless and move at the speed of light, but when the higgs interact with most of them, they move slower and gain mass. but it's more more hard to explain that to the public without tehnical terms. if you start talking about particle coupling and Z emission and spontaneous symmetry breaking and weak hypercharge, people will get bored and leave.

@Imafungi123 11 лет назад

How does something with no mass (higgs field) give mass to something with no mass ( Particles before they supposedly interact with the massless higgs field) ? When was the first moment "mass" existed, and what caused it to exist? Is mass in essence, quanta that does not travel at the speed of light?

@7777Ralph 11 лет назад

The double slit experiment proves the universe isn't what a lot of people think it is. There is no way to make sense out of photons changing based on our observation. I see many here think up scenarios to explain it, but those hypotheses have been proven wrong. If you research more videos, you will see that. It has been proven, just exactly as this video says, that it truly is the act of observing that changes the nature of a photon. This is intelligent design folks, very clearly.

This is gibberish: "The total energy of the universe is precisely zero, because gravity can have negative energy. The negative energy of gravity balances out the positive energy of matter. Only such a universe can begin from nothing. The laws of physics allow a universe to begin from nothing. You don't need a deity. Quantum fluctuations can produce a universe." - Lawrence Krauss, physicist, con man

@sammyfromsydney 11 лет назад

Science is my hobby, not my profession though I do have a degree in Astronomy. Listening to that, I wonder if there could be a relationship between the Higgs instability and dark energy. This is all handwaving on my part as I do not know any of the math, but could it be that the universes' acceleration could be caused by the Higgs field. ie. the field "stretching out" and pushing space apart, thus avoiding the instability...just a thought

@sidewaysfcs0718 11 лет назад

the higgs field. the higgs field itself is massless, and normal particle WOULD be massless, but because these 2 categories interact, the particles we see have mass. only 2 particles wich don't interact with the field are photons and gluons (and possibly gravitons)

In 1977 Gould wrote, ‘The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology. … to preserve our favored account of evolution by natural selection we view our data as so bad that we never see the very process we profess to study.’5

@Folkstone57 11 лет назад

A super dense particle would probably be rather massive. It might not attract any other particles & the more dense/massive the particle, the faster it will either break up into lighter particles, or if it's very dense it would exceed its Schwartchild radius & would collapse into a black-hole & then dissolve .

@Imafungi123 11 лет назад

but anyway, you are relating this to the higgs field having no mass (but assumedly energy?) and so all the energy created in the big bang was massless until it hit the energy of the higgs field, which caused it to have 'mass'? I just dont know what he higgs field would be, it seems to perfect that the universe would belch out an all invasive, invisible, energy field which allows the affect of mass. Why cant the energy of the universe have an intrinsic mass without a higgs field?

Consciousness as far as we know depends on the physical brain and body,and consciousness itself may have mass,if it is related to the firing of neurons and brain activity such as that,so it takes relatively lots of energy to remain conscious,according to einstein that energy can correlate to mass in some way,music depends on physical objects with mass to be vibrated against other materials and through air,the sound wave is energy,while I dont know if sound wave has mass, it can impart its energy

@TeunLos 11 лет назад

Light refracts through glass, not bending. Thats something different entirely. So you are basicly stating that gravity pulls the photons of light and thats why the light is 'bend'. Eventhough countless experiments have prooven that gravity has no grip on photons (or quantum packets if you like) and that light always goes in a straightline but looks bend because of the curvature of space time.

@mrgoldie109 3 года назад

An amusing but plausible explanation. Higgs boson particles are photons playing “hot potato” game. Very simple. A very hot potato, a form of dark matter, a fractal of inadvertent matter from the Big Bang. Of course, the Higgs boson will be unstable - who can hang on to this hot potato? - because it will transfer the hot potato to its nearest neighbor. The photon may or may not have temporary increase in mass depending on its state in the game aka as spin. And, sometimes the hot potato gets dropped, adding no mass to the photon, no spin.

(cont.) IN CONJUNCTION with whatever spiritual ideas / materials base their beliefs. For example- "God", nothingness, creation, and the idea of a multiverse... Could not our universe have been generated as the result of asymmetrical quanta from another universe/s being aggregated in a new one (ours)? This would facilitate a practical balance of seemingly incongruous phenomena- explaining both creation and the idea of a universe from "nothing". Furthermore, would a consciousness with a "higher"

@sidewaysfcs0718 11 лет назад

that last explanation is not really accurate ...at all , the higgs field didn't create all particles, in fact all models show that in the early moments of the universe all particles were masslessless, and then the higgs field "consdensed" mass into the particles.

@sidewaysfcs0718 11 лет назад

this isn't a guarantee, if nature has a fundamental level, wich means it's basic fields cannot be split into composite parts, then nature truely does have undivisible components. already we see this in a way, particles in the standard model do NOT have components. a photon can split into an electron- and positron, but it is NOT made up of those two. an electron in turn can absorb a photon , or emit it. a gluon can also split into two quarks , and quarks in turn absorb gluons.

@chandrasah38 11 лет назад

Originally, the author Peter Higgs called it God Dame particle. But, the editor of the journal refreshed it (because they can't publish this word) and called it God particle.

@Levon9404 11 лет назад

It is hard to believe in this video clips what I heard from Lawrence Hall, the speaker introduced him as physicist. He spoke about gravitons does he really serious? I'm having difficulty understand, physicist well aware of gravity is a mass-less energy, what kind of graviton he is talking about? Than he mention three type of field electric, magnetic, gravity what hell is that if he is truly physicist, he should have known that all three fields are the same they come out of nuclear force.

I'm curious as to why and how the Americans seemed to have muscled in on the outcome of the predictions of an Englishman (Higgs) and the endeavour, beginning in 1954, which resulted in the world's largest Hadron Collider, and the consequent discovery of of the Higgs Boson. As far as I know, 20 European states have provided the sole financial and academic expertise in this venture. Yet there they are, American voices lording it over the successful efforts of other nations.

I give different enterpretation to the God's Particle, it means God's servant, for Higgs Boson fill all regions in this universe, and it's the particle that gives mass to all other particles in this universe, it gives mass to electron through Higgs field, of course it doesn't interact with photon, and Higgs Boson particle is special because it's a manifestation phenomenon of Higgs Field which comes from no resource, Higgs Field just exists in this universe, more over it can decays in two photons or in two Z bosons.

@MrKorrazonCold 11 лет назад

Mass Higgs-field vector +Mu of the universe acting upon accelerating mass +/-m from a distance radius! Thus limited range of Spherical inward + and - outward waves and Doppler causes a redshift. Redshift with distance is a consequence of less energy exchange, less wave 'boson' interactions with distance, less Inward spherical EM-waves acting upon +(you)- and outward waves now accelerating from other ref-frames acted upon by their own observable spherical region of the infinite Universe."

Very rarely do I post anything. However, in this case I must comment. Anecdotal ideas / concepts have no place in scientific (experiment / observationally verifiable) debates or inquisition. Religion and science both principally seek truth; therefore they ought support each other rather than oppose. Religious narratives from a pre-scientific age can NEVER be used to discredit EMPIRICALLY OBSERVED scientific data. Intelligent people of faith use science to shape / refine their beliefs

If it didn't dissolve, it would be a black hole of a kind that current science would have no understanding. However, if such a thing did happen, there would be little to worry about if that's what you're leading up to. It would be no danger to anyone or anything other than particles smaller than its even horizon. If the earth collapsed to a black hole, its event horizon would only be about a centimeter across. Although we would all be gone, it wouldn't endanger anything larger than a centimeter.
