A Glimpse of the Sun [4K]

[@SirLoin2418]

It's wild to think that a single light photon, from the sun, takes nearly a 100,000 year journey from its core, to it's surface , but then only 8 minutes to reach Earth. I love physics.

[@Akash-uq8wg]

Lots of matter to bounce again and again, then its free willy.

[@Xirrious]

That doesn't even make sense. When a photon is absorbed and then later another photon is emitted again, it's not the same photon emitted that was absorbed. Photons don't travel from the core at all. There is no way, even in principle or theory, that we could track a photon making this journey. It's an entirely conceptual model, not empircal, certainly not a fact. A model, and... That model isn't accurate at all. It makes even less sense when you realize a photon is just a potential probability in a wavefunction until we observe it...

[@Akash-uq8wg]

@@Xirrious a paradox!

[@PNWMAK]

Yeah and relative to the photo no time has passed from it’s emission to its impact of our eyes or sensors

[@tommy-er6hh]

Here is some more info to go with this excellent video: Sun - a solo, oddly calm, G2V Type yellow dwarf Star here Power sources -loss - Photo-disintegration of deuterium (also called photo-transmutation) causes power loss as atoms break up to a simpler state. This process keeps on going through all the stages of the Sun, but speeds up as more energy is produced, then when it shines dimmer as a White Dwarf the reaction happens less. -loss -The slow neutron-capture process, or s-process creates new elements/isotopes at a cost of energy like in Red Dwarf Stars, but over thousands of years for each atom. This keeps on going through all the stages of the Sun, but faster as heat increases. -loss - as the Sun heats, it sends out the Solar Wind/exosphere which takes energy/loses mass. This happens more as the Sun gets brighter. + gain has initial temporary power from gravitational compression at the start of its life. +gain -Radioactive Decay like what happens in planets also give a teeny amount of energy. Yes, the Sun has heavy radioactive elements inside it, like Earth. +gain -Free Deuterium(Hydrogen with a neutron) & free Lithium fusion burning, like Brown failed Stars, have finished very quickly as our Star starts. +gain -After that the proton-proton chain/PP fusion is the main source of power, making more new deuterium,. which is then fused into helium-4 per the Deuterium Reaction; but it happens more quickly than in Red Dwarf Stars. The PP chain initiates at about 15 million K in the core. +gain -the CNO reaction (CarbonNitrogenOxygen) catalyst makes Helium-4 is also present, but scientists argue about how much (0.4% to 10% right now). The CNO catalyst reaction becomes dominant at about 17 million K or in stars 1.3 times more massive than the Sun. future Sub giant stage - the core gets clogged by helium “ash” elements in electron degeneracy, so Fusion reactions start moving outward, with makes our yellow-white sun bigger and hotter giving off more Solar Winds mass.. future Red Giant stage Helium Fusion is next after Hydrogen is gone, causing the outer shell of the Sun to expand. + gain -After Helium-4 is made the core & sun shrinks and then carbon forms via the Helium Fusion Triple Alpha process. This reaction is simple. Two Helium-4 nuclei (aka alphas) Fuse together and form Beryllium-8. This Beryllium-8 nuclei is further Fused to a Helium-4 and forms a stable Carbon-12 - this reaction requires a temperature of 100 million K. -loss -As the Carbon “ash” builds up, the electron degeneracy causes a second red giant stage. During the last stage of this reaction the Sun has thrown off it outer shell into a planetary nebula. Future White Dwarf After our sun finished creating Carbon and it has thrown off it outer shell into a planetary nebula, it’s left over core is too small to go any further. It collapses into a white Dwarf, all the Carbon possibly ends a huge hot carbon electron degenerate (diamond like, but much, much heavier) core. + gain -possibly a thin layer of Hydrogen or Helium remain, with a little Fusion going for a while. + gain -It cools and begins to release heat of crystallization as main source of energy. Unless it gains more material to burn on the surface from a nebula. Example Sirus B Future Black Dwarf After it cools too much, no reaction occurs, no left over heat is left to glow, the Sun would be come a cinder. ---------------------------- The Sun, a spectral class G2V main-sequence star 99+% mass of solar system; Helioseismology (echos of vibration of sun-quakes seen in light) shows the layers: a. 20-25% Core {CNO 1-10% of energy & the rest mostly pp fusion followed by deuterium fusion ending with fusing 2He3 to stable He4 - about 2/3 of the Sun’s Hydrogen has been used up in the core, 2/3 is already Helium; also >0.1% is radioactive decay/Lithium burning/fission}, b. ~50% semisolid Radiative zone {also has some reactions which produces >1% of fusion energy}, thin Tachocline border below which the Core & Radiative zone plasma rotates as solid and above which the plasma layers act as fluids, and in Tachocline some scientists think is the source of the Sun's Magnetic Field. c. ~25% fluid Convective zone still 2/3 hydrogen and 1/3 helium, other scientists think the Convective zone is where the Sun's Magnetic Field originates. d. observed Photosphere/(surface) sometimes with 11 yr sunspots [And Sun’s surface does not act as a solid, different latitudes rotate differently, 25 days at equator, 31-35 days at poles - also the plasma flows to poles at surface and below the Photosphere the plasma flows deeper but slower back to equator.], e. Chromosphere the reddish ”lower atmosphere” where temp rises, f. Corona [where magnetic field rules the plasma finally, below this the plasma pushes around the magnetic field, and here temp shoots way up.], and g. Heliosphere/Solar Wind/plasma/ interplanetary medium (which goes out past the planets to Heliopause); The Sun’s magnetic field squeezes in on the side so that more high speed jets of matter and energy from deeper in the Photosphere exit out of the Sun’s poles, this is the cause of the Heliosphere croissant like shape; also the Sun’s magnetic field flips every 11 years - cause unknown. The Sun's Magnetic field goes out to the edge of the Heliosphere along with the Solar Wind. The Magnetic Field interacts with the Solar Wind to slow the Sun's rotation over time, but soon it should stop, given what we have seen in other stars as they age. h. Sun's interplanetary (HMF) where the Sun's gravity still rules, but the local nebula's [yeah, we are inside one] plasma and magnetic field rule out to the theoretical Oort cloud; The dwarf planet Sedna orbits way out here along with the Voyager probes leaving. [Note: stars 30% of the Sun mass are thought to have no radiative zone, only the core and convection - and stars 1.2+ more massive than the Sun it flips with no outer convection zone, only radiative, but the core itself becomes convective.] Extinct Comets and asteroids impact sun, or close in orbit perigee 100+ per year, most unseen except for IRIS & IRAS solar satellites.

You should make a video on the fermi paradox, with a personal in depth analysis of the chances of there being life or intelligent life in the universe. That would be super interesting.

[@sea_space]

What do you mean “personal”? Do you mean break the fourth wall to say what I think? I don’t think that would be quite the way I’d want to go with it. I did a video on the Fermi paradox but it was a very long time ago and was much worse quality than mine now. I’ll bear that suggestion in mind but the Fermi paradox has been done pretty extensively on KZbin by now. It’s also one of the things that stops me making more videos on the end of the universe, because you can’t really top what’s already out there (melodysheep)
