RAZOR visits the Compact Muon Solenoid (CMS) experiment, one of the Big Four particle detectors at CERN's Large Hadron Collider, which is part of a groundbreaking search for ‘new physics’ that defy our current understanding of the universe.
CMS is one of the largest international scientific collaborations in history, and one of its many tasks is helping find evidence of dark matter - a mysterious substance that makes up about 85 percent of the total matter in the universe. That's more than five times as much as ordinary matter - which is what everything we can perceive in the universe is made of.
Particle physicist Claire Lee explains how CMS is looking for evidence of ‘dark photons’ - exotic, long-lived particles that have an average lifetime of more than a tenth of a billionth of a second.
They're called “exotic” because they are not part of the Standard Model of particle physics. Senior physicist Jamie Boyd explains that although the Standard Model is the leading theory of the fundamental building blocks of the universe, it doesn't answer many other questions about physics, and so searches for phenomena beyond the Standard Model continue.
Senior physicist Jamie Boyd explains how the detectors are looking for those phenomena, while magnetics engineer Mirko Pojer talks us through the LHC's next big upgrade.
We also hear from theoretical physicist Marc Riembau Saperas, who explains how he and his colleagues sift through billions of data points produced every day. And we take a look at the next project that CERN wants to build - the 100km long Future Circular Collider - which will push the boundaries of our scientific knowledge even further.

The idea of expanding the standard model or the existence of a dark standard model I'd mind blowing. Whether particles are simply too heavy to detect or too light in terms of their interactions, I'm excited to see what the upgrades to the collider will reveal.

I got a question I would love if you answer it Let suppose we got a single white light photon ( 7 colour waves superimposed on each other ) we hit that photon on the prism and it passes through the prism and gets detected on a screen then what would we see on the screen ?
@AlphasysNl
@AlphasysNl 3 месяца назад
White light doesn't exists by itself. You've basically answered your own question. If you superimpose 7 discreet wavelengths of light, you will have 7 discreet photons that will hit 7 different spots after diffraction through a prism.

@newmyself2153 3 месяца назад
@@AlphasysNl how do these 7 photons look means are they stacked on one another or are just like one inside another ? Also why doesn't white light exists itself isn't white light a wave too but it is just a different pattern than other color waves

@@newmyself2153 White light by itself does not exist correct its your brain making red+blue+green = white. There is only light with a certain wavelength (color). They do not interact with each other, so they can be at the same place at the same time (they are neither inside each other nor stacked on top of each). The reason why a prism splits them is because they travel through the material with different velocities (light is not at light-speed outside a vacuum).

@@ABC-vd1zl thanks bro for clearing this doubt , 😊 my next doubt is let us suppose we took 2 waves one of higher energy and other with low energy superimposed on eachother now we pass that new wave through prism would that new wave too interact with prism ? And what would be the result on screen also if we don't observe that new wave hitting the prism does it means it's wave function won't collapse and it would just pass through prism without interacting also tried asking chatgpt he says that when one white photon goes through prism it randomly chooses to became one of the seven colour and we see only one colour on the screen and same with this low and high energy wave only one wave would be seen because it's wave function collapsed .please help clearing these doubts and can u please suggest me which RU-vid channel to follow to do detail study on this topic 🥺

24:55 I hear a lot of people saying the same about NASA/Space flight, as it costs tons of money, takes a long time to give results, takes even longer for the general public to benefit in some cases... However, my question to them is: Are you aware of all the the benefit you're already getting? PC's, Smartphones, would be decades behind; then there's stuff like freeze dried food, and the battery driven drill are due to the space industry

I think we need to go back to r² and the three dimensional physics of the Inverse Square Law! Spherical 4πr² geometry is fundamental to this process and this is based on Huygens’ Principle of 1670 that says, “Every point on a light wave front has the potential for a new spherical 4πr² light wave". We can think of each point as a potential photon ∆E=hf electron interaction as resonance or vibration. The spherical 4πr² surface forms a boundary condition or manifold for the uncertainty ∆×∆pᵪ≥h/4π of everyday life. The centre of the sphere forms a constant of action relative to the radius square r² and the circumference 2πr. This forms the Planck constant h/2π in mathematics of Quantum Mechanics

There are 7 Tesla MRI machines... I've been in one. This machines magnet is still probably bigger by a number of other measures, but 3.4 tesla isn't all that crazy. Most modern MRIs are 3 Tesla. TMS treatments use at least 3 Tesla. But these all operate via short pulses. If this one's a constant 3.4 tesla, that's well over 20 amps continuously just for a small coil. A coil that size would draw huge amounts of power.

The answer in what gravity is, is in the beginning of this video. It is not a part of the standard model, Its the effect and will (if you can call it that) of all matter, to return back to its natural state. Matter is a residue from high energy events and it immediately seeks equilibrium with its unmanifested state. Gravity is not a particle it is a universal balance.

More PR from CERN. Opens with some guy marching along to, "lively," music to create an impression that things are going, "somewhere." In fact CERN, (The LHC,) hasn't actually delivered any result of any real significance since it was built, (and upgraded,) other than the Higgs Boson. Certainly non of stuff we had been promised and were expecting, (the lighter Supersymmetric partners of the Standard Model particles at the very least,) of which so far still not a trace. There's all kinds of strange and exotic theoretical stuff that's, "possible,", the actual experimental evidence for which remains nil. Personally think this is just B-S. The next discussion will examine the vexed and difficult problem of, "How many Angels can dance on the head of a pin," and must they be Quantum Entangled in order to do so ?

Why are we spending our money on this stuff, who cares, why are we wasting our money? You never hear people ask that about “art.” In fact the same people that ask that question are many of the same people you’ll find going to the art museum to be cultured. Are we so self obsessed? Are the fever dreams and emotions of some artist of obvious value while literally the secrets of the universe and the fundamental nature of reality are just boring nerd quests? A boring nerd quest that common people didn’t see the value of was quantum mechanics and relativity. Our entire modern world and economy is now inextricably dependent on these theories. From the microprocessor to gps to mobile phones. But no one saw the practical uses at the time. But more pointedly, if all we care about is eating and mating and social hierarchy gossip, and what other humans are thinking, how are we any different from dogs or cats or monkeys? The thing that makes us different is a fundamental curiosity. A drive to understand our world and to probe the underpinnings of reality. Because there is where the real beauty lay.

- We live in the same climate as it was 5 million years ago - I have an explanation regarding the cause of the climate change and global warming, it is the travel of the universe to the deep past since May 10, 2010. Each day starting May 10, 2010 takes us 1000 years to the past of the universe. Today June 03, 2024 the position of our universe is the same as it was 5 million and 138 thousand years ago. On october 13, 2026 the position of our universe will be at the point 6 million years in the past. On june 04, 2051 the position of our universe will be at the point 15 million years in the past. On june 28, 2092 the position of our universe will be at the point 30 million years in the past. On april 02, 2147 the position of our universe will be at the point 50 million years in the past. The result is that the universe is heading back to the point where it started and today we live in the same climate as it was 5 million years ago.
