Mahesh, this video is amazing! Such great story telling with such a surprising conclusion. I’ve always believed heavy elements come from super nova too, without stopping to wonder how we “know” this. Thank you for fixing this misconception!
I’ve been struggling to figure out why I like Mahesh so much… there are plenty of RUclipsrs out there and some are great at explaining stuff. You’ve put your finger on it: what makes him so good is storytelling. I am a nuclear physicist and I knew all of this before the video started and yet I was fascinated the entire time, and practically cheered when Tc was revealed as the proof of the Slow Process. You know somebody is talented when they can teach you something that you already know well and still make it interesting.
@@Mahesh_Shenoy"Brother, please clarify the misconception about pseudo force. Some people say it doesn’t exist in reality. However, my question is, if it’s not a real force, then why does a pendulum, initially at zero angle in a car, tilt at an angle when the car starts moving?"
@@Abdulllnajeeeb67 Pseudo force in reality doesn't exist I think you are studying in 12th class and so you must be using Newton's laws of motion But NLMs doesn't work on non-inertial frame; so to convert non-inertial frame into inertial frame, we use the concept called pseudo-force You are saying that when the car accelerates, the pendulum swings back. It is due to the inertia and as the car attains constant velocity, the pendulum stays back at the same position. Since the car accelerates, we use the concept of Pseudo-force in the opposite direction of acceleration. But in reality it is inertia
Finally you've started your shirt line. I've always searched for your shirts online and found it hard to find. My favorite is the "Entropy it ain't what it used to be" shirt
Mahesh, I almost skip the video, thinking yes I Know it is neutron stars colision. But man, I happy I trust you , you deliver great content, thank again. By the way, I am curious about R-process why gold and platinum are the stables products.
Thanks :) So jn S process, it makes sense that end products would be stable isotopes with neutron magic numbers, right? Well, in R process they would be unstable products (neutron rich isotopes) with neutron magic numbers. Which would beta decay to these ones.
I am amazed I haven't heard about the S-Process until just now, and this paper is not new - it's quite old ! Thanks so much for a great video on this topic.
@@ShawnHCoreyBut how's possible ,Only when the neutron contains the masses of proton,anti neutrinos,and electron only then it is it possible isnt that...
I was on a break from RUclips, i have got tons of ur videos to watch... Hope u remember me from my profile pic, m one of ur old subs Anyways, i have a suggestion, can u cover good Olympiad level questions on this channel? They r also super fun to do! I mean, how slowly we analyse questions, to build our understanding and try approaches is awesome when it comes to Olympiad level questions!
Good take, Mahesh. Most of us had the idea of heavier elements coming from supernovae, S process was something I learned from quantum major at grad school 🤯🤯
I've seen other R/S process videos, but none ever explained the reasons so well. Ditto for fusion stopping at iron. Thank you for the excellent explanations!
Can you make a video on horizon problem and explain how big bang can happen for quantum fluctuations? Also explain singularity of big bang... people have many misconception about big bang theory.
Why haven't I heard this before?! I am so glad that there actually are some people that are so intelligent that they can figure all the Physics out. That is truly on another level.
Another awesome video. Who knew I’d look forward to physics lectures after plodding through them in college? When one makes the complex understandably simple, then one has mastered the topic. Great idea with the t-shirt collection: witty and smart 😊 Also, found the B2FH paper online. Thanks for the reference, Mahesh. Keep up the amazing work!
Sir I have a question. Why do electrons gain energy as they move across the battery and if battery transfer 12 joules of energy per coloumb then how can we have 12 joules of energy drop in three resistors connected in parallel battery gives only to 12 joules to 1 coloumb and we are having 12+12+12 =36 joule of energy loss in resistors Doesn't it violate law of conservation of energy
Chemist here. Until I saw this video, I was still telling people the elements heavier than iron were created by supernovae. So glad to see such amazing scientific breakthroughs. I’ll tell people half of those elements were created by dying stars from now on.
Man I love this video, as a chemist who tries dabbling in physics and astronomy in my spare time, this video was a perfect combination of all three. Plus the story telling, and build up to the conclusion was phenomenal.
I too believed that all metal must have cooked in supernova. Brilliant. The sheer pleasure you feel while describing i also felt the same. Proud of you.
Fantastic vid, well explained with enthusiasm. I've been thinking, ok, this is where the elements come from, but where do the basic compounds like water and rocks come from. Can elements combine as plasmas in stars, or are the compounds floating in space formed elsewhere?
Via the S-process in end-of-life-stage stars (maybe the red supergiant star Betelguese in the constellation Orion) looping down the wormhole called technetium, the chemical element at Z=43.
If you want to find uranium ore, the solubility of uranium salt and access to material from down deep under is the rabbit hole you should go to. Yes, volcanoes are a signpost because magma from deep down under can come up through them. Uranium is *HEAVY* so we should look deep or from deep. The Earth's crust should have been thin before so that magma could punch through. Former shallow seas tend to have thin crusts.
I'd love to see a video on entanglement and quantumbits one time. Its a topic I find hard to understand. You always explain things in such a great easy to understand way.
When I studied Physics & Astrophysics 1999-2003, we were taught the heavier elements came from supernovae, although the mechanism was never mentioned. At one point I was discussing this with my father (a chemistry lecturer) and he looked at me like I was daft, and said simply, "no. S-process ". Fun (read pedantic) fact: There was also Lithium created in the Big Bang.
Thank you for one more mind blowing video for the year! I appreciate your channel and how it helps simplify and grow my knowledge of these topics. Even if my wife looks at me like im crazy.
Hi Sir, I’d love to see a video discussing the possibility of alien life. Could you explore the different levels of alien existence, such as microbial life, intelligent civilisations, and even the Fermi Paradox? It would be interesting to hear about the scientific perspectives, the search for extraterrestrial intelligence, and what the future could hold in terms of discovering or communicating with aliens. Thanks!
There's actually little to be said scientifically. Most scientists will assume the chance of other life out there (if only single cellular) as about 100% because assuming life on Earth being unique means designating the Earth as a very special place in the whole wide universe. SETI was about trying to find technological signals. But things such as radiowaves would take a lot of time to travel between stars and would loose a lot of strength. We're starting to approach a level of technology where in certain cases we can get glimpses of exoplanet atmospheres and that could indicate the presence of biological life. As for communicating, little chance at that. Even if we send a signal and get a response then optimistically, we would still be limited by the speed of light. So even if we found an Earth-like planet with biological signs... if it's at 25 light years away, sending a signal and receiving one back would take half a century. So, sure, there's probably life out there, perhaps even intelligent... but at distances impractical to visit or even communicate.
Microbial life is probably common in the Universe because the chemical elements of life on Earth is made of: OHCNSP should be very common arising from the Boltzmann's distribution of the baryons forming various atomic nuclei on the nuclear binding energy chart. Life isn't special. Earth is a lot more special though (eons of liquid water and hot molten core with geomagnetic field to shield life from being fried by the solar wind) so intelligent life is extremely rare. Fermi Paradox is easily explained by intelligent life destroying itself almost immediately upon gaining nuclear technology. We have already been to the brink of nuclear war dozens of times in the last century.
Try to communicate with MAGA folks of the U.S.A. to satisfy your desire to have a conversation. It's much more accessible than communication with extraterrestrial intelligence.
Another great topic and explanation Mahesh Sir❤. Thankyou for your valuable research and teaching. Learned a lot new facts. You are and you will always be one of the best Teacher I ever had😍.
In the end heavier elements do keep being created in a supernova event. If not by fusing lighter nuclei because they can get photodisintegrated (as if photons suddenly became a wall of destruction sweeping over the escaping nuclei) at least part of the neutrons created by the implosion of the iron core will carry over the necessary energy for it.
Your videos simplify complex topics and generates curiosity. Well, why would observing technitium in dying stars necessarily mean it is produced from within? Why cannot it be a case of accretion as with planets? Also, once a stable element of lower weight is produced in S process, will it not stop attracting more neutrons thereby not forming heavier isotopes? How do the heavier elements then form?
Currently I study in class 12 preparing for my jee. A few weeks ago I got to know about your channel when I searched for some modern physics stuff. Since then I have become a fan of your intuitive ways. Now your videos have become a source of refreshment for my brain after studying for long hours.😉

12:58 For lead at least i'm pretty sure it can again be explained by radioactivity. Basically atoms do R-Process and get shit ton of protons, and we know everything heavier than lead is radioactive, and everyone then decays into lead
I am fortunate to have been born in an era when Mahesh was able to have these amazing conversations with all these scientists! 😅. Amazing channel, amazing science, amazing storytelling!🎉
Temperature is a statistical property of a collection of things. Photons are things so a collection of them has temperature. The thermal spectra arising from the equilibrium of photons with the walls of an oven in Berlin was what Max Planck was trying to account for when he had to use energy quantization E(photon) = h × f(photon) where h is Planck's Constant. Photons' energy spectrum was what brought us all into the quantum era in the Atomic (i.e. 20th) Century. 🎉

Hello and thanks for this interesting video content 😊 Heavier elements - and all other gaseous and metallic molecules - are primarily electromagnetically made in galactic centers, thus forming everything, all according to the available "gas and dust" when the formation takes place. This is why very strong gamma- and x rays are beaming out from galactic centers. Regards Ivar Nielsen Natural Philosopher Denmark
Hi my friend. Can you make a video about the difference between momentum and kinetic energy?I have been always wondering.What is the difference?I don't understand it
Last time I checked, the jury was still out on this one. Normal SN II create them, but s- and r-process does in no way account for the abundance of heavy elements. Neutron star mergers could account for that, but there are heavy-element-rich (IIRC Europium-rich) star clusters that are too old to have been enriched by neutron star mergers, so there is a need for another mechanism, which might be rare types of SN. See Alex Ji and Ken Croswell.
I remember watching a video on youtube it was related to astronomy, and I am still looking for it and haven't found it, the narrator says this one thing that sticked to me" any element out there in the universe, we have it here, it has to be in our periodic table, so when you are holding the periodic table you are holding the entire universe in your hands" it was amazing and i regret not having watched it completely but even more unfortunate i could not find it anywhere on youtube, I guess a black hole ate it up😂... anyone knows it please give me the link I desperately need to watch it....
Hey Smart guy! Can you make the most intuitive video on ' why we can't see the interference pattern in YDS experiment, when we place a detector to observe which slit does the photon passes thruv'..... I know you can!
Dude. You trolled me. You know how videos start autoplaying on mobile and dont show the thumbnail for long? I was scrolling up and down cause I still didnt get what was written on the right half 😂
Sir I want to ask that when electrons reaches the positive terminal of the cell then the cell pushes the electron towards it's negative end and also transfers energy and electrons uses this energy in the appliances so my question is when the electrons are traveling because the cell repels the electron from its negative terminal towards its positive terminal due to electrostatic force during this the cell has not transferred energy yet because cell transfers energy when the electron is inside it and in this they are traveling towards the positive terminal of the cell but are not inside the cell so I think during this phase the electron must not have gained any energy because they are going to the cell but they are not inside the cell to get energy from the cell so I think the appliance would not work for few mili second until they reach the cell and the cell transfers energy into it am I correct or they got some energy while they were traveling to the positive terminal? If yes then how?
How do the elements from these S-process stars then get distributed out into the universe? Are these stars large enough to nova or supernova themselves or are there old dying red dwarfs with lead cores like cosmic fishing weights out there?
Lemme guess, is it a beta decay, and beta decay chains? Learned of those from the Victor Ninov episode of BobbyBrocolli, but i think that can also be applicable in stars right?
The black part of the star turns material at high enough dimensions because the information density slows down in the higher dimensional soup. The black part made the star a data power core, but after 16,777,216 pick 64, it goes backwards. It becomes predictable, like a space elevator at a hindu math convention.
I think an honorable mention should be the RP-process (rapid proton capture) which happens in Hydrogen rich environments, where a compact object (typically a neutron star) accretes matter from the atmosphere of a nearby companion star. It will build a layer of proton rich material on the surface until it reaches a critical temperature and the protons merge with neutrons and explode away in a nova flash. This cycle repeats regularly, and in some cases (called the common envelope phase) the neutron star can be *swallowed* by the atmosphere of its companion, creating an extremely interestic dynamic system. RP can produce elements up to Tellurium.
In regards to supernova explosions... I heard recently that the core collapse bounce model actually doesn't work on its own, and that the majority of the force in a supernova explosion actually comes from *neutrinos* of all things, the nearly massless particles produced in unfathomable amounts every second that usually pass through entire stars as if they weren't there. Way I heard it was during a collapse, things are *so* dense, the number and intrinsic energy of neutrinos actually begin to matter where they ordinarily wouldn't, and that's the source of most of the power in a supernova. I feel like if not that, then neutrinos in general, could be a great topic for a future video. Especially to answer the question why we're so sure that neutrinos *aren't* dark matter, when they're so numerous and ghostly that it feels intuitive to assume that they would be at least a substantial portion of it.
Neutrinoes can't be dark matter, becouse of their speeds. This is particle that naturaly moves with the speed being very close to the speed of light. The way that dark matter affects normal, visable matter, requires from it to be built from slow particles.
Great discourse - very intuitive and physical! But please run it by me one more time as to how those heavier than iron elements end up in the vast gas and dust clouds which THEN can end up in a newly formed planet like the earth when those clouds collapse to form a new sun and planetary system? Oh, and thanks for enlightening me about the contributions to science by Margaret Burbidge. She actually almost lived to age 100 !!!

hi, big follower, i have a doubt, though protons are less heavier then neutrons, how can a proton convert into neutron during beta decay
@@SciSil2121 damn, i never thought of it before
@ Because sometimes the mass of the system can decrease. Consider two protons in a nucleus. They have a much higher mass than a proton and a neutron.
@@Mahesh_Shenoy so, it is the strong nuclear force that gives extra mass?

Life isn't special. Earth is a lot more special though (eons of liquid water and hot molten core with geomagnetic field to shield life from being fried by the solar wind) so intelligent life is extremely rare.
Fermi Paradox is easily explained by intelligent life destroying itself almost immediately upon gaining nuclear technology. We have already been to the brink of nuclear war dozens of times in the last century.
Try to communicate with MAGA folks of the U.S.A. to satisfy your desire to have a conversation. It's much more accessible than communication with extraterrestrial intelligence.

Last time I checked, the jury was still out on this one. Normal SN II create them, but s- and r-process does in no way account for the abundance of heavy elements. Neutron star mergers could account for that, but there are heavy-element-rich (IIRC Europium-rich) star clusters that are too old to have been enriched by neutron star mergers, so there is a need for another mechanism, which might be rare types of SN. See Alex Ji and Ken Croswell.
Great video. Thanks. 👍
Cool. Thanks for sharing.
I remember watching a video on youtube it was related to astronomy, and I am still looking for it and haven't found it, the narrator says this one thing that sticked to me" any element out there in the universe, we have it here, it has to be in our periodic table, so when you are holding the periodic table you are holding the entire universe in your hands" it was amazing and i regret not having watched it completely but even more unfortunate i could not find it anywhere on youtube, I guess a black hole ate it up😂... anyone knows it please give me the link I desperately need to watch it....
So how are the elements heavier than lead and barium synthesized? Uranium?
T_Shirt failed: what about Li (not that much created) and may be Be?
Very good video as usual.
FloatHead is terrific!
Hey Smart guy! Can you make the most intuitive video on ' why we can't see the interference pattern in YDS experiment, when we place a detector to observe which slit does the photon passes thruv'..... I know you can!
Dude. You trolled me. You know how videos start autoplaying on mobile and dont show the thumbnail for long? I was scrolling up and down cause I still didnt get what was written on the right half 😂
😅 sorry!
You can turn them off.
Amazing avatar. ;-)
@@thingsiplay Ah, a man of culture as well :)
Sir I want to ask that when electrons reaches the positive terminal of the cell then the cell pushes the electron towards it's negative end and also transfers energy and electrons uses this energy in the appliances so my question is when the electrons are traveling because the cell repels the electron from its negative terminal towards its positive terminal due to electrostatic force during this the cell has not transferred energy yet because cell transfers energy when the electron is inside it and in this they are traveling towards the positive terminal of the cell but are not inside the cell so I think during this phase the electron must not have gained any energy because they are going to the cell but they are not inside the cell to get energy from the cell so I think the appliance would not work for few mili second until they reach the cell and the cell transfers energy into it am I correct or they got some energy while they were traveling to the positive terminal? If yes then how?
Mahesh, you are the most engaging presenter ever, pre and post-YT!
How do the elements from these S-process stars then get distributed out into the universe? Are these stars large enough to nova or supernova themselves or are there old dying red dwarfs with lead cores like cosmic fishing weights out there?
Love your T-shirt.
Lemme guess, is it a beta decay, and beta decay chains?
Learned of those from the Victor Ninov episode of BobbyBrocolli, but i think that can also be applicable in stars right?
Great video!
FYI the words “astronomy” and “astronomer” are pronounced with emphasis on the 2nd syllable, like a-STRON-omy and a-STRON-omer.
You are the reason I love physics now (I want to meet you , I live in karnal,haryana)

The black part of the star turns material at high enough dimensions because the information density slows down in the higher dimensional soup. The black part made the star a data power core, but after 16,777,216 pick 64, it goes backwards. It becomes predictable, like a space elevator at a hindu math convention.
I think an honorable mention should be the RP-process (rapid proton capture) which happens in Hydrogen rich environments, where a compact object (typically a neutron star) accretes matter from the atmosphere of a nearby companion star. It will build a layer of proton rich material on the surface until it reaches a critical temperature and the protons merge with neutrons and explode away in a nova flash. This cycle repeats regularly, and in some cases (called the common envelope phase) the neutron star can be *swallowed* by the atmosphere of its companion, creating an extremely interestic dynamic system. RP can produce elements up to Tellurium.
The more I learn about science, the more I realize that the scientific process is just really clever detective work.
I like how "Or is it?" become the universal standard for every science-relared quesions.
Under whitch stone did you find your information?
This is great, thanks
In regards to supernova explosions... I heard recently that the core collapse bounce model actually doesn't work on its own, and that the majority of the force in a supernova explosion actually comes from *neutrinos* of all things, the nearly massless particles produced in unfathomable amounts every second that usually pass through entire stars as if they weren't there. Way I heard it was during a collapse, things are *so* dense, the number and intrinsic energy of neutrinos actually begin to matter where they ordinarily wouldn't, and that's the source of most of the power in a supernova. I feel like if not that, then neutrinos in general, could be a great topic for a future video. Especially to answer the question why we're so sure that neutrinos *aren't* dark matter, when they're so numerous and ghostly that it feels intuitive to assume that they would be at least a substantial portion of it.
Neutrinoes can't be dark matter, becouse of their speeds. This is particle that naturaly moves with the speed being very close to the speed of light. The way that dark matter affects normal, visable matter, requires from it to be built from slow particles.
The first time this guy has made a video about a question I already knew the answer to 😅 still an amazing watch though
Great discourse - very intuitive and physical! But please run it by me one more time as to how those heavier than iron elements end up in the vast gas and dust clouds which THEN can end up in a newly formed planet like the earth when those clouds collapse to form a new sun and planetary system? Oh, and thanks for enlightening me about the contributions to science by Margaret Burbidge. She actually almost lived to age 100 !!!
I never cared about physics... until now! thanks to Mahesh's videos
me too. only slight interest but when someone would start explaining stuff, my mind would just wander away. this channel is curing that :D
Good video again, great topic! ;)
what exactly du mean by ‘depending on how you think about density’
