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 UA-camrs 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.
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.
@@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
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.
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.
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.
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
@@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...
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.
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 🤯🤯
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.
"actually it's going to be super easy, barely an inconvenience!" hahaha, wonderful Ryan George quote. also, I love your enthusiasm in all your videos so much. ❤
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!
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!
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.
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!
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.
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!🎉
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.😉
I was on a break from UA-cam, 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!
Found your channel today and end up watching till here. I love your explanation and want you to explain atomic orbital theories in detail ( Schrodinger equation and more )❤ . Please
Nature giving coulombs barrier the finger. How do work a line like this into one of the best educational videos on the internet and have it still be amazing. Keep making videos because they're all awesome.
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.
Its amazing how much we know about these collosal celestial bodies based on all the elements present in our own teeny tiny earth! How amazing! How tiny yet significant are we!!
I know you sort of recite your explanations anyway at the end I'm always moved. sometimes I cry. Even if you add some emphasys I feel you had experimented on yourself before the emotion of understanding what we are about to understand too thanks to your explanations. I love it. Merry Xmas and thank you for making me feel better
I think they are fomer during R-process. Let's consider that as he said , during the R-process sometimes elements will be skipped . I.e. if gold, platinum,barium,lead are skipped somehow than these elements could be formed. Remember that Uranium is not one that is formed in large numbers as gold or platinum. So if a star explodes with enough force, and neutrons above a limit are received by the atom that it forms let's say gold, then after if the same gold comes across a neutron star collision 💥 it may recieve more neutrons and form very heavy elements like thorium,protactinium or Uranium. I hope you understand😊
Wikipedia: The r-process also occurs in thermonuclear weapons, and was responsible for the initial discovery of neutron-rich almost stable isotopes of actinides like plutonium-244 and the new elements einsteinium and fermium (atomic numbers 99 and 100) in the 1950s.
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😍.
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.
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
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....
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
I recently watched a UA-cam channel called SCI PHILE THE AI. The host explained that sometimes the core of a dying star, which typically becomes a neutron star or a black hole, is destroyed by the explosive force of a supernova or hypernova. This explosive force can occur faster than the core's ability to collapse into a black hole or neutron star, preventing its usual formation. I always believed that the fate of a massive star was either to become a neutron star or a black hole. Learning that these explosions can obliterate a dying star's core, leaving nothing behind, completely blew my mind.
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.
Personally I am a student of 8th standard and still don't care what I am learning . I literally tried to learn everything about space and science. I knew quite a bit about ideal gas law in 7th standard. But all the things I don't understand as due to having not the developed brain , this guy explains anything to me and I understand it like it's 2+2😊. Sir you are a great teacher and I respect your devastatingly high energy levels❤
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.
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
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.
After the star explodes the escape of high energy electrons is viable. So the coulombs barrier fails the stable star and it collapse generates an explosion outside of it that lets stuff escape quickly. Light even has a hard time getting out of a star when it is stable. Some say 100 years for a photon generated at the core to find its way to the surface.

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?
@@Mahesh_Shenoywhat about the mass energy equation? I mean some energy being converted into mass.

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.
@@FrancisFjordCupola Thank you so much for your thoughtful and detailed response!
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.
I had an alien registration number assigned to me when I arrived in the U.S.A. so yeah, you are talking with a former "alien."
After the star explodes the escape of high energy electrons is viable. So the coulombs barrier fails the stable star and it collapse generates an explosion outside of it that lets stuff escape quickly. Light even has a hard time getting out of a star when it is stable. Some say 100 years for a photon generated at the core to find its way to the surface.
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 :)
You are the reason I love physics now (I want to meet you , I live in karnal,haryana)
Such an amazing channel!
You are so criminally underrated 😢
T_Shirt failed: what about Li (not that much created) and may be Be?
Very good video as usual.
awesome as always 💪🏼 can u make a video about stars life cycle?
Good video again, great topic! ;)
Woah, now m gonna read that paper if its available online
