Why does the sun shine? Why doesn't it burn out? How long will its fuel last? To a scientist living in the 18th century, he might have compared it to a log in a fireplace. When wood burns it releases about 1 ten-millionth of a trillionth of a watt per atom.

5:00 How fusion happens
7:19 Quantum tunneling
8:25 Fusion chart
9:51 Where energy comes from
12:39 Why Helium is more stable
15:14 Future of sun
The mass of the sun was well understood, and translates to about 10^57 atoms. This leads to a lifetime of the sun of about 20,000 years. But we know the sun is at least 4.5 billion years old. So where does the sun's energy come from? from: E=MC^2, which tells us that energy and mass are equivalent. If the sun could convert all its mass 2 x 10^30 kg to energy, it would burn for 15 trillion years!
But the sun doesn’t convert all its energy to mass. It converts only about 0.7 percent of its mass to energy in a process called fusion. This is when 4 hydrogen atoms fuse to form one helium atom. And using this process, the sun will last approximately, 10 billion years. It is already middle aged.
So how does fusion work? You would think that since the protons that make up the nuclei of the 4 hydrogen atoms are positively charged, they would repel each other. This is true, due to the coulomb force. This is what keeps atoms from spontaneously fusing.
The protons have to overcome an energy barrier. Once they get over this barrier, and get very close to each other, the strong nuclear force takes over and glues them together.
The strong nuclear force is about 100 times stronger than the electromagnetic force pushing protons apart, but it acts at only a very short range - about the width of the proton. So how do the protons get close enough for this to happen?
Inside stars extreme temperature, about 15 million degrees Celsius, rips atoms into their components: protons, neutrons and electrons. Extreme pressures also force these components to be close together. This gets fusion started, but to keep things going, the sun uses quantum tunneling. This is due to the uncertainty principle in quantum mechanics.
In the hydrogen to helium fusion process, first two protons fuse. Usually, the pair breaks apart again immediately, but once in a while one of the protons is transmuted into a neutron. This happens due to the weak nuclear force in a process called beta decay. A neutron turns into a proton by releasing a positron (anti-electron) and a neutrino. The resulting proton-neutron pair is deuterium.
When the positron emitted from the beta decay encounters its antiparticle (an electron), the pair annihilates to form a gamma ray, which is the most energetic form of photons. Gamma rays eventually work their way up from the core of the sun and out into space in the form of sunlight. The deuterium nuclei can merge to form helium nuclei (He-4), or they can interact with other protons to make another isotope of helium (He-3). Two He-3 nuclei can fuse to make an unstable beryllium nucleus (Be-6) that breaks apart to give He-4 and two protons. Energy is released at each step.
So overall, we start with 4 hydrogen nuclei, or 4 protons, and end up one Helium nucleus, or 2 protons and 2 neutrons. This is really a fusion of our 4 original protons. Two of them have just transmuted to neutrons in a beta decay.
Energy comes from mass being converted to energy. 2 neutrons and 2 neutrons separately weigh more than when they are together, about 0.7% more. And this difference is responsible for nearly all the energy that you see coming from the sun.
Helium has higher binding energy than Hydrogen, which is the amount of energy needed to pull the nucleons apart. Hydrogen has zero binding energy because there is only one proton in the nucleus. There is nothing to pull it apart from. The difference in binding energy between Helium and hydrogen is the source of the energy released in the fusion process.
Why are the 4 nucleons of helium more stable together than when they are separated apart? Most of the mass does not come from the Higgs field. Only about 1% of the mass is due to the Higgs field. 99% comes from the strong force. The energy required to keep protons and neutrons bound together and keep the quarks bound to within the nucleon is where most of the mass of objects is located.
#fusion #sun #quantumphysics
The helium atom with 4 nucleons is more stable than the nucleons on their own. That is the quantum mechanical explanation of why the sun shines.

@KZread official c^2 = 1 in Einstein's theory of General Relativity. Dark energy = repulsive gravity or negative curvature, hyperbolic space. Positive curvature is dual to negative curvature -- Gauss, Riemann geometry. Real black holes rotate or spin close to the speed of light, when a large star collapses its angular velocity must increase to conserve angular momentum, think of a spinning ballet dancer who brings in her arms to her sides. Dark matter is empirical proof that black holes are spinning close to the speed of light -- relativistic effects. You must add the energy due to rotation and angular momentum to the rest mass of the black hole and this amplifies or increases the net mass of the black hole -- this is completely consistent with General Relativity. Black holes therefore contain a lot more energy/mass than is currently accepted because of rotation and hence the gravitational force is a lot stronger (dark matter). "Perpendicularity in hyperbolic geometry is measured in terms of duality" -- Professor Norman Wildberger, universal hyperbolic geometry. The relationship between dark energy and dark matter is dual. The big bang is a Janus hole/point (two faces = duality) -- Julian Barbour, physicist. Topological holes cannot be shrunk down to zero. Divergence (the big bang, white hole) is dual to convergence (black holes). Attraction (gravity) is dual to repulsion (anti-gravity, dark energy). Thesis is dual to anti-thesis creates the converging thesis or synthesis -- the time independent Hegelian dialectic.
Arvin, you pointed out a very important fact-in the Sun's nuclear reaction, only 0.7% of the mass gets converted to energy. In fact, one of your viewers asked why not a 100%. I explained the law of conservation of baryon number as well as I could. But I'm sure a video from you would be worth a 1000 times as much. Yup, that's a request-a video on the lesser-known conservation laws such as charge, parity, baryon number, lepton number etc. I have another reason for requesting this. Some enthusiastic but misguided proponents of nuclear fusion forget this 0.7% limit. They tell you how much energy _E_ we humans consume, how much fossil fuel we burn for that energy, and how much pollution we cause because of it. Then they use Einstein's famous _E = mc²_ and arrive at a ridiculously small amount _m = E/c²_ of uranium, plutonium, or some other nuclear fuel that could replace all those gigatons of fossil fuels. A lot of naïve people get convinced by such false arguments. But, as you mentioned in this video, they are off by a factor of more than 140. But you did not explain why. In order to have a rational and fact-based discussion on such topics, it would be nice to have the science explained in a simple and clear fashion, as you do in your other videos.

The reason only a small amount of mass gets converted into energy, is because our Sun is too large to have convection currents. Red dwarfs don't have this limitation, due to reduced gravity and convert almost all hydrogen.

@@lordgarion514 No, that's not it. The only way to convert all of hydrogen into pure energy is to get an equal quantity of anti-hydrogen to annihilate each other. On the other hand, if you have only matter to begin with-no antimatter-you won't be able to convert it all to pure energy. Doesn't matter what kind of reaction it is-chemical, biological, nuclear fission, nuclear fusion. Doesn't matter where it takes place-in a lab on Earth, in the Sun or some other star, white dwarf, red dwarf, neutron star, supernova, quasar ... some matter will always remain behind as matter, without getting converted to energy.

If I understand correctly, it's 0.7% of the mass involved with the actual successful reactions occurring at the core. There is a lot hydrogen just sitting around in a hot bath of plasma heated by the energy coming from the core before it heads towards the planets. Not all hydrogen "collisions" at the core will fuse to helium at any moment, but nothing is stopping it from happening in future moment. I'm then curious what percentage of the core is actually fusing over a period of time...let's just say 1 second.
Can you believe some people think that the earth is flat...??? !!! They are missing a whole world of physics, chemistry and astronomy!
Arvin does such a great job of explaining things that he might be the world's single greatest source in terms of making the world more intelligent.

So basically you want to make a Kerr Metric black hole via Kugelblitz? As for whether the space would still have gravity the answer is yes as gravity comes from the energy density in a volume of space not just its rest mass. Once the black hole is formed the content of the space within the black hole becomes meaningless you need to think of black holes not as a physical object but as a scar in spacetime. Hawking radiation then is the effect of this scar distorting the quantum fields which drives the resulting scar to "heal". The question of what happens to matter that falls in is thus far unanswerable with a number of hypothesized solutions In fact as he pointed out here most of a nucleon's mass is bound up in the energy of the quantum field interactions and photons i.e. quanta of light are the mediating bosons of Quantum Electro Dynamics(QED). All this is to say that once the black hole is made anything on the inside is unknown causally disconnected.

@@brianpj5860 The short answer to your question is yes Have you looked into David Kipping's Halo drive proposal? It describes how this could be done with astrophysical black holes using them to both accelerate and decelerate spacecraft at high speeds. There are two forms of energy accessible from this the rotational angular momentum of the black hole locked within its ergosphere and the orbital angular momentum between two or more co orbiting black hole binaries. The 3 main limitations are the complexity of calculations needed to know where to aim the ability to aim with the necessary precision and of course access to an astrophysical black hole. Kugelblitz black holes would likely be far too small and short lived to be able to fill this role unless you say fed them entire stars worth of mass/energy.

A nucleus, like other physical systems, tends towards a state of lowest energy. A neutron will decay into a proton (plus an electron and electron antineutrino) if the nucleus with the proton has a lower energy state than the original. In stable nuclei the possible lower energy states are all filled, i.e. they are each occupied by two protons with spin up and spin down, so beta decay does not occur. A free neutron, outside of a nucleus, is actually unstable, with a half-life of about 10 minutes and 10 seconds.
