The Sun uses quantum tunneling to create nuclear fusion, but only can achieve this through it's large mass. So how can enzymes in our body achieve this feat?

  • $\begingroup$ Quantum tunneling has very little to do with mass. $\endgroup$ – probably_someone Mar 23 '18 at 21:30
  • $\begingroup$ yes it does; the more volume and mass in a object, the more likely quantum tunneling will occur. $\endgroup$ – BiologyIsLife Mar 23 '18 at 21:33
  • $\begingroup$ The likelihood of quantum tunneling depends only on the height of a particular energy barrier, the energy of the tunneling particle, and the frequency of collisions with the energy barrier (i.e. the degree of confinement). The Sun creates a high degree of confinement with gravitation, but that's the only way that mass comes into it. We don't need a lot of mass to create fusion on earth - all we need is high magnetic fields. $\endgroup$ – probably_someone Mar 23 '18 at 21:42
