So the Sun isn't hot enough for fusion to take place if there was not Quantum Tunnelling happening, thank you that's the kind of answer I was looking for.
Hi, I'm just after a definitive answer on how Hydrogen fuses into Helium in the Sun?
Some places say the Sun is so hot that they overcome their same charge repulsivness and fuse together while other places say that our sun is not hot enough for that to happen and that they just get close...
