What Is Quantum Tunnelling?

Luckshay: Quantum tunnelling is what quantum tunneling is. In the quantum world, at the ultra microscopic, sub atomic level, particles can actually go through wall. Even when it comes to black holes,. hawking radiation, hawking radiation can be calculated as a tunnelling tunnelling effect, quantum tunelling effect. Luckshay says, the rate of a formation of stars in a galaxy depends on wat factors, right? For star formation to happen, you need molecular hydrogen, hydrogen molecules, which is essentially atoms. And not just diffuse molecular hydrogen, but molecular hydrogen clouds.
