What gives particles mass? That's a very different question to what gives stuff weight. And it's one that physicists have been asking for centuries...

To all my willing interviewees who I peppered with questions - Clara, Sam & Aaron - you guys are the best for giving up your time. Also, a giant THANK YOU to Michaela Livingston-Banks (of Nailing Science fame) who took time away from the desk to follow me around with a camera all week. And a HUGE thank you to Stephanie Hills at CERN for scheduling this whole trip - she was my inbox fairy ❤️

Was doing a bit of rockclimbing at the time so it was ok really. He was nice, quiet, very polite. I wonder how those windows are doing, you cant replace with pvc in that part of Edinburgh.

Seems like such a simple solution, and it was. Just an unknown factor, not the observations or equations in the wrong.

I remember watching almost 25 years ago the fantastic TV series "Reality on the rocks" with the late actor and writer Ken Campbell as the host. The series deals with quantum physics and we visit CERN where a slightly younger John Ellis tries to explain to us what quarks are. We also get acquainted with Roger Penrose and David Deutsch, among others, and their theories of general relativity and quantum computation. Of course we also meet Stephen Hawking where he tries to explain to us when gravity produces singularity. This is not easy lessons for lay people like me, but still very interesting. Thank you very much for a nice and informative channel on KZfaq. Keep up the good work :)

You're correct. Dr. Becky should have made the distinction between the mass of the fundamental particles and composite particles, a.k.a. 'stuff'. For e.g. protons and neutrons, the majority of the mass comes from, like you said, the binding energy of the quarks by the gluons.

@maus3454 4 жыл бұрын

Actually the mass or resistence tomotion originated from the fact that those half-spin particles change spin direction. So called Zig Zag effect. Particles without mass don’t encounter this. So they don’t experience time to take this change of spin direction. Where does Higgs field kicks in, is to cover the conservation of the iso spin charge.

@guillaumebeuf5050 4 жыл бұрын

Yes: The Higgs field is only responsible for the mass of many fundamental particle: electrons and other leptons , quarks , neutrinos (even though the story is possibly more complicated in their case) , W and Z intermediate bosons ; and it contributes to the mass of the Higgs boson itself via self-interaction. However, all this gives only a few percent of the mass of ordinary matter. Most of the mass in the atomic nuclei comes from the strong interactions between quarks and gluons bound within protons or neutrons.

@LuisAldamiz 2 жыл бұрын

@@shashankchandra1068 - Not sure. Generally 'rest mass' is meant to imply the intrinsic (Higgsian) mass of fundamental particles. The more common definition of mass refers to that characteristic that confers both inertia (resistance to change in motion) and gravity (curvature of space-time) and that's what best approaches your description. AFAIK some physicists (but not many others) sometimes use "rest mass" as opposed to momentum or so-called "relativistic mass" (a misnomer for many), for example in photons having their trajectory bent by the gravity (space-time curvature) of a massive object (a star, black hole, etc.) I think this is because they dislike gravity not being quantum and would love to see the extremely speculative graviton hypothesis proven true. However photons' momentum does not alter their inertial properties (if any at all) and thus it's almost certain that does not cause any gravity either.

That's actually a good question. The Higgs Boson, was looked for, not because they wanted to find the particle per se, but because it would be the indicator that the Higgs(et al) field existed. Or more accurately that what is call the Higgs Mechanism is what actually exists. I think it is because the field of high energy physics came from a particle based background, and it wasn't until QFT was formulated, it was quite realise that fields are what is important, and that particles are a sort of epiphenomenon of the fields existence. This is, I admit my poorly understood version, but I think it's not too far from the truth.

In effect, each force has its own field, but some particles interact with more than one field. Or as in the case of photons, and the Higgs field, they don't interact at all.

If I may be so bold: I think your conclusion that we can't travel faster than c because we can't turn off the Higgs field is not correct. The speed of light is the fastest speed of transmitting information in our universe. Only massless particles are travelling at this speed, because they don't interact with the Higgs field at all. Thus, they can't be slowed down. If the Higgs field was turned off, any massive particle would instantly be travelling at the speed of light - but not faster than that. A question I still don't have heard a good answer to is how the Higgs field relates to gravity in either GTR or quantum theory (or preferably both; yeah I know I'm getting nasty... ;-)).

It's impolite to talk about quantum gravity.

@antonystringfellow5152 4 жыл бұрын

Good question! When something falls towards a source of gravity, its speed increases yet it doesn't feel any acceleration at all. On the contrary, we only feel that kind of force when we contact the surface of a gravity source (as standing on the Earth). So, either space is falling towards the gravity source (as we don't move through it) or the Higgs field is. Maybe the Higgs field IS space. Never thought of that before!

Nobody knows the answer to your question AFAIK. There's a Nobel prize or a dozen awaiting to whoever finds the answer. It should be discussed more, we want the answer now!

@LuisAldamiz 4 жыл бұрын

Anyway my take is that, per Einstein, energy slightly curves space-time around it. That is a field, the field of fields because all other fields exist in space-time, and it does not seem to have a quantum answer. I'm rather for relativizing QM than for quantizing GR (which is the mainstream current approach but is leading nowhere) but I don't know enough nor am bright enough to go further.
