How Does the Large Hadron Collider Work? | Ars Technica

I didn't realise relativity also affects the background music too, it seems to get louder and louder towards the end of the video 🙄.

[@marcosavbg]

LOL, indeed. But... what is the music?

[@gmt-yt]

​@@marcosavbg Seriously! Assuming the original audio was properly mastered, but whoever made this video didn't listen/care/understand/notice/etc, I wouldn't mind knowing who made it at all! Well... the subtitles would have been a natural place to throw a harmless bone to the music guy/gal/band and they didn't (instead describing it, here, as "[Music]" and on Ars, IIUC, inexplicably, as "". Which seems like maybe they didn't want to tell us or didn't know. Or, maybe they accidentally drag-dropped the wrong audio file into the track at the last second before hitting "save" and said "good enough, whatever, but who the hell is that!? Maybe the subs guy didn't know and tried to call the production guys but they were out having a taco and left their phones in the car.... My hunch, is, if you called them on the phone, found the right department where they actually cut this video, and asked nicely... they'd be able and willing to tell you. Note the "main" place for this content is presumably, in their minds, the ArsTube, or whatever you want to call the embedded video player over on their website. Comparatively, it plays on garbage audio codecs (or, maybe on fine codecs but at very low bit-depth, etc. -- basically it sounds like GSM, masking the horrible redlining in a sea of equally horrible compression artifacts :))

They just film it that event of particles collision with slow motion cameras and other heat seeking vision sensors- but at the same time the bits and pieces created of the smallest particles after collision get to go out in the open and escape, don't you find it odd the technology created this thing, it's probably not how everything's beginnings started ,but still that question(how everything started?) puzzles a whole lot of scientists If there is light but most of it resides in darkness of space and equally day and night! what could be our beginning?

[@benjamn8557]

Great explanation but what's the point of colliding protons?

[@shayanmoosavi9139]

To learn more about their structure. What we have found so far is that the protons are made out of even smaller particles named quarks and gluons. There's a whole new branch of physics called particle physics. Its job is to study these fundumental particles (you can look up the standard model of particle physics). So far we have been able to explain three of the fundumental forces (electromagnetism, weak nuclear force, strong nuclear force) by this standard model but gravity hasn't fitted into the model yet. A hypothetical particle called graviton may be responsible for gravity but no evidence of its existence have been found. It's a very interesting branch of physics. I suggest you learn more about it :)

[@nihaal7750]

@@shayanmoosavi9139 but what will colliding them do? How will we get to know its structure by colliding them?

[@shayanmoosavi9139]

@@nihaal7750 think about it this way. Suppose we have two hollow glass balls which we can't see inside of them and inside them are 3 metal balls. By colliding them hard the shell will break and the metal balls will scatter. This is a simplified version of what happens in a particle collider. They'll collide bigger particles like protons and even some ions together with an extremely high velocity (almost at the speed of light) and study the scattering pattern of the smaller particles that emerge. They're called elementary particles because they're not made out of anything else (at least as far as we know). for example electron is an elementary particle but a proton isn't an elementary particle because it's made out of quarks and gluons. This is as far as I currently know about it because it's an advanced subject.

I'm curious if this tech could be used to shoot ships across the universe at near light speed say you built one around the earth and instead of shooting atoms into each other you put a ship inside and have an opening that can be controlled to open since it is using magnets from my understanding or magnetic fields so couldn't you have an opening where it's just held in by the field and turned off an near light speed Wich also makes me wonder if it could be shrunken and used to make a new form of gun that speeds up some sort of bullet just a thought....

[@chrisell2823]

my only question on this is why dont you reverse it. have the larger wheel start it up and push it to the smaller one for greater speed not only would it take less energy but you could multiple the speeds

[@madhavakinnicutt5371]

my guess is it would be harder to keep the particles from crashing into the sides of the tube. From what they said that's already kind of hard with the large one.

[@migueltovarguerrero2582]

Exactly, @Madhava Kinnicutt. The centrifugal force would grow exponentially and it would be too hard to keep the beam in its path.

[@joseph6270]

see 3:17, the same reason why the turns on highways are much larger and gradual than those in neigborhoods

[@locke8847]

I'm not too smart but what is tripping me out is that these particles are moving hella fast in respect to the speed and time of the scientists.. like they are prolly bored and napping while protons are zipping at speeds of light which freezes and shrinks outside reality to the light speed traveling particle. In fact if it went faster than light then reality and the scientists would be moving backward in time to the particle. So two different time space deals are going on in the same time space... I think once the particles stop or slow down at the end is when all of space time connecting the two different places reconfigures back as a whole. Like all they are really doing is making twists in a blanket and thinking that the different twists are different parallel realities and then when you untwist the blanket after the collider is turned off, little effects show up like creases, lines, and stretches on the fabric of space time.

Are we sure that. We cant push particles to the soeed of light simply because the machine can't keep up. Its signals and everything take time to travel. Has anyone thought of that and fine tuned it. What if they just program the machine to function as if the particle is going light speed but after reaching 99.9999% C. Its not hard to imagine at all. Imagine standing in the ground and look at the moon. 200,000 miles or so away. 1.2 seconds and you'd be there at light speed. If you've ever driven a 4000 mile trip... Do it 50 more times and that's how far away the moon is which is 75 days by car without stopping. Light does that dame 50 trips every second.

No, the protons have mass...they can only approach speed of light, never attain it. Gravity might affect the Standard Model as we know it but it's very small effect. Even if a collider is made in zero gravity, it won't have much significant changes in the results for us to detect.

[@evanulven8249]

Not quite. Earth's gravity well certainly effects the particles in the collider, but C (the speed of light) is, to the best of our knowledge and understanding of current physics models, the hard speed limit in the universe.

What would happen if a person got trapped in the particle accelerator and was exposed to all of the high-energy protons?

[@Usul]

Good question that shows lots of curiosity. I like that. The beam pipe the LHC uses is pretty small. Fitting inside would, well, require you to be compressed to less the diameter of a soda can. That already can't be good for you. On top of that, it is a near total vacuum and is at minus 270 Celsius. You'd be turned in to a long, thin, meat popsicle at that point. The full "nominal" beam in the LHC contains quite a bit of total energy. Most of the beam would pass right through whatever shape your popsicle-body took inside the beam pipe. What part of the beam did interact with your body would deposit a fair bit of energy. It would result in the machine immediately detecting a fault and the beam would be removed from the machine in a fraction of a second. If we turned off all those safety systems and just let it go... It would probably cause your popsicle shaped corpse to be cooked near instantly, resulting in a small steam explosion from the water (your body is mostly water). This would probably destroy a dipole magnet or two, and make one heck of a mess someone would have to clean up. It would probably take a few months to fix, and leave everyone baffled as to how you got stuffed in there without anyone noticing. Overall, I wouldn't recommend the experience.

So the explanation of the proton getting heavier the more it accelerates towards the speed of light is wrong therefore his reasoning behind the positive charged particles repulsion being a negative effect is wrong.. objects don’t actually change mass as they go faster, think about it, it’s all relative, if I’m moving near the speed of light in space I don’t feel a thing and everything around me is accelerating past me while I experience stationary... I certainly don’t experience a change in mass

[@BlueCosmology]

You're right that mass doesn't change, but nothing he says about positive charged particles repelling is wrong.

[@paulgraham2483]

The rest mass does not change, but both the momentum and energy of the particle approach infinity as its speed approaches c. Some people still like to say that the particle's mass approaches infinity. They're not actually wrong; they're just using "mass" and "energy" as almost synonymous terms, while most of us these days prefer to let "mass" always mean "rest mass", and keep energy as its own independent concept. The difference is only terminology. The actual testable question -- how much energy does it take to get a proton to such-and-such a speed? -- comes out the same by either method.
