The addition of the children at the end was brilliant. I like your station very much. I am old and have found a love for learning about the universe. It is so amazing beyond words for me. I like the simplicity of your videos. Seriously, they are short and very sweet. Thank you
Best explanation of the Nuclear forces! There's no need for neutrinos, gluons, and stuff like that which may be important in reality, but not when teaching. Clean, simple, and informative enough for the layman.
I have been studying the sun myself due to lockdown. This explination, after many, excited me so much that it filtered into my dream last night. THANKS!
Amazing video and great animation! Even more amazing is the fact that "beta decay" occurs due to quantum tunnelling..Quantum tunnelling is incredible rare, but there is so enormous amount of Hydrogen atoms in the mass of the sun ,that this tiny possibility happens all the time!!!!!!!! How can't man love science?!
Wow, so happy to have found this clear and beautifully explained video. Looking forward to uncovering the no doubt many more gems on your channel. Thanks!
@@ItsJustAstronomical Wow thanks. I just uploaded one of my own songs about the heat death of the universe and how this could be used as a chat up line... I've got a whole album coming called 'The Physics Of Us'. I can't decide if they are mainly love songs disguised as songs about physics or songs about physics disguised as love songs!
@@callmynamesebastian Interesting, you know, everyone's got their own idea of what's hot, what turns them on. As much as I love physics, it just doesn't do that for me. But you may be onto something. There may be an untapped market for physics love songs.
Thanks so much, you not explain the nuclear fusion, but also introduce the related knowledge such as chemical reaction, and you also concluded the key points by the kids, I suddenly see the light, subscribed, thanks so much!!
@@life42theuniverse What's bothering you man, do you have a question about fusion, I've learned a fair amount about it and could probably help answer/ steer you in the right direction for an answer
About the video: Amazing! Incredible! Fantastic! Wonder! Super! However, I have a question: since the mass of a neutron is bigger that of a proton, and since the formation of a helium 4 involves the fusion of 4 hydrogen atoms, each one with one proton in the nucleus, what is the origin of the energy released during this nuclear fusion? This energy came from electrons? After all, in the beginning we have 4 of them and in the end there are just 2. I also do not understand the relation of beta decay with nuclear fusion. The explanation would be in the fact that a collision between a proton and an electron produces a neutron and a neutrino? If this was clarified, the video will become even better!
Where did the energy from come? It's actually really similar to chemical reactions. When you combine hydrogen and oxygen to make water, you make energy, where did that energy come from? It came from the fact that you formed a more stable chemical compound. The same sort of thing is happening in nuclear reactions. What you say about electrons isn't exactly right. I'm showing you the interior of an atom. In fact, the hydrogen in the core is a plasma meaning that the electrons are not tied to the protons. When a proton turns into a neutron through beta decay, it spits out a positron, and a neutrino. A positron is an anti-electron. It will find an electron and annihilate into pure energy, but that's only part of where the energy is coming from. Beta decay is not a result of a collision between a proton and an electron. The proton spontaneously decays into a neutron, a neutrino and a positron.
And there's also gravitational energy in the form of tides and radioactive decay of the elements inside the earth. That's why I said "practically" all the world's energy. Our energy overwhelmingly dominated by the Sun.
@@ItsJustAstronomical Yep, the heat from inside the earth represents less than 0.1 % of the energy we get from the sun, so I guess I forgot to talk about the energy released by the heated arguments on twitter, which must be about the same percentage.
There is one statement here, repeated, which I think could have been put better. At about 2.00, we are told tha certain combinations of atoms are more stable than others, and when they are brought together they "make energy". Actually, energy, properly understood, cannot be made, or destroyed. It can only be transformed from one form to another. (In the transformation, it is also degraded, increasing the amount of disorder in the universe, but that's another subject.) It would have been better to say that th energy 'stored up' -- the potential energy -- in the uncombined atoms, is released by speeding up the atoms which release it -- which we experience as 'heat'. However, this is just a small point -- overall, this is an excellent video and I hope we see more like this.
Step 1: 1.442 MeV, Step 2: 5.49 MeV, Step 3: 12.86 MeV. Steps 1 and 2 happen twice for every one Step 3. So the total is 26 MeV. MeV means million electon volts. Most chemical reaction only give you a few electron volts, so this is extremely energetic.
@@almoni127 The weak force has a similar pattern to the other forces. What's actually happening is an exchange of W-, W+, or a Z bosons. In fact, the weak force and the electromagnetic force have been unified into something called the electroweak interaction. I don't fully understand the details, but there's unified model that describes both forces. The reason the weak force is so weak is because the W-, W+, and Z bosons are pretty massive and thus harder to produce. Here's a diagram showing beta decay as an exchange between particles: en.wikipedia.org/wiki/W_and_Z_bosons#/media/File:Beta_Negative_Decay.svg
@@ItsJustAstronomical Thanks for your answers! So all steps are about the same order of magnitude. Did not expect that. (I did search a bit after asking and found out about beta decay and W/Z bosons)
i have a question: 7:02 why is it Helium 3 and not Hydrogen 3? I mean, those being 2 protons and a neutron can be taken as a hydrogen nucleus with an extra proton or a helium nucleus without a neutron.
The number of protons determine the chemical properties of an atom. Hydrogen-3 exists but it has completely different properties because it has two neutrons and one proton.
Dude....Thank you so much! Like every other video or article on the web just shows 4 hydrogen atoms coming together to form a helium atom (helium-4). 2 neutrons magically appear out of absolutely no where, right when the 2 protons fly away....I keep asking myself..."where the eff did those neutrons come from??!!") Thank you for the 3-step process.....it actually makes sense now! (I have to explain this to a class of 8th graders, so I won't look like an idiot thanks to your video!)
6:45. I am curious how two protons colliding and creating a proton plus a neutron could release energy if the neutron is slightly heavier. Shouldn't the creation of more total mass absorb energy? I guess that is where the decay comes in.
What we have learned ? Humans really dont know the big things in this world or in space . Our brain is not created for this . Thanks god that science never find out this amazing stuff about gods power ! Makes me really happy. Human history had shown what people with power are able to 😲
if it takes 1 billion years for 2 protons to trigger natural beta decay, and only 4 second for deuterium to combine into helium, how come the fuel does not end when all deuterium is consumed really fast but no new ones are created as fast?
Small amounts of deuterium are continually being produced in the core. For each proton it happens at random over a billion years. There is some naturally occurring deuterium. Most of it was burned up a long time ago. This is the difference between a normal star like our Sun and a brown dwarf. A brown dwarf has enough mass to burn deuterium, but not enough mass to make much of it through beta decay. Brown dwarf run out of deuterium quickly, but our Sun constantly makes more of it.
I have a PhD in Nuclear Fusion and the quality of your videos in general , and this one in particular, blows me away! Thanks so much!
It does not explain the black spots we see on the sun, only electric univers channel explains this.
I had a hard time following you there, but those kids really helped bring the conversation back down to my level.
This is the best explanation of the sun's nuclear fusion! Thank you very much!

Great video - I remember being taught the PP1 cycle in Astronomy at university. Great to see the kids showing us nuclear fusion.
As always really good concept and explanation, you give the background first before jump into main topic, really like that...
Keep it up sir
This explanation is really a blast, first lay a good background work, then with extremely clear explanation of forming fusion reaction + cute kids
This is the clearest explanation of fusion I've found yet on RUclips. Thanks a bunch!

Great video! What is the amount of energy released in each of the 3 steps?
Also, why the weak force is a "force"?
It seems so unrelated to the other 3 forces, which are forces between particles.
Step 1: 1.442 MeV, Step 2: 5.49 MeV, Step 3: 12.86 MeV. Steps 1 and 2 happen twice for every one Step 3. So the total is 26 MeV. MeV means million electon volts. Most chemical reaction only give you a few electron volts, so this is extremely energetic.

No energy is released instead when 2 protons are close due to the electric repulsion.
