The Sun can’t work without Quantum Tunneling

The Sun's core is 15 million °C (27 million °F), which is hot enough to turn gas into a plasma. But thermodynamics isn't enough to explain nuclear fusion at those temperatures. It needs quantum tunneling!

The Sun uses quantum tunneling for nuclear fusion and nuclear fusion is how the Sun creates light... so, is this the light at the end of the tunnel?

[maxim_km]

Everyone tells about protons bumping in stars, but nobody has ever mentioned quantum tunnelling before, even in school, where we had an excellent astronomy and physics teacher. As always, new video, new interesting fact.

[GlenHunt]

I knew there was a non-convection zone in the sun but it never occurred to me that it isolates the core from additional hydrogen. Now a lot more about stars is making sense! Thanks Nick and Question Clone! What a team!

[XtReMz]

I remember reading a while back that quantum tunneling is the reason why modern electronics struggle to shrink size of processors due to transistor plates being too close to one another, allowing quantum jump of electrons. I really enjoyed your video Nick :D

[AndrewDotsonvideos]

Every time I thinking’s done a good job explaining something you make a new video and put me in my place lol.

[Andrew-epkw]

A book I read put the quantum tunneling process in the sun in an interesting perspective. Since the probability of a fusion event for any square meter of core material was extremely low, an equal volume of compost actually produces more energy. The book said the sun doesn't produce so much energy because it's efficient; it produces it because it's so huge.

[Will-be-free]

I have been wondering why the sun doesn't just use up it's hydrogen all at once. Thanks for explaining.

[fep_ptcp]

Fact about the Sun: sunspots are actually quite bright spots on the surface of the sun, and if observed isolated they would be brighter than the Moon. They appear as dark patches only because of the contrast with the surrounding area of the sun's photosphere, which is considerably hotter and brighter

[vineetasingh]

Actually my teacher told us in high school that source of sun energy is quantum tunneling but he just told the fact. After 2 years I finally found it complete .✌

Very complex concepts : made it look so simple! Once again, Brilliant choices of models/illustrations!
5:40 "Wave Particle in a box with a lil' tail sticking out" = Best illustration of Quantum Tunneling I've seen yet!

Great video Nick! I would have loved you to discuss some applications of modern technology that use quantum tunnel. For example, I recently learned SSD's VNAND rely on electron tunneling in order to write information to charge traps. Also, you should try doing video premieres- even if it's an hour away premiere, it would be good to watch your videos with you and then have a 5-10 min discussion about them.

[outoftheboxtalk]

Thank you. I have been explaining this in my grade 6 class for the past few years, and now I have a video to go with it! In fact, CPUs can't get much smaller because "quantum tunneling sets a fundamental limit on how small transistors can get. If any internal barriers get thinner than a nano-meter, too much current will tunnel through when the transistor is off." -QUANTUM MECHANICS IN YOUR PROCESSOR

[seanspartan]

You've really outdone yourself here. I learned so much in a single video. Thank you for making and sharing these!

[darkiusdark]

NDT has put it clearly when he said “ if you have sample size [of probabilities] large enough, rare things become common”

[nooneatall]

The sun is a lot more badass than I thought.

[Broockle]

o, that finally explains the difficulty of building a fusion reactor.
Amazing Vid :D

[charliemcelveen]

Hi Nick. It’s so great seeing your channel grow. I started watching years ago when I think your subscriber count was in the single-thousands. Keep up the great work. Not only are you explanations...lucid...they are also readily accessible by me, a mere mortal. I a really appreciate your work.

[UltimateBargains]

"The Sun can’t work without Quantum Tunneling"
Yet another ridiculous union demand...

[technicallittlemaster]

This was a whole new fact to grab
Never thought that fusion in stars would require quantum tunneling.
That's great, that's awesome!!!
Keep on the good work
