I don't get the whole proton-proton deuteron reaction that takes place within a star.
It should be p+p+e- --> H2 + neutrino
However, the overall energy for the process is insufficient for it to take place.
Can anyone rectify this for me?

You don't need much energy for fusion to occur when you're under over 9000 megafucktons of pressure.

We're currently assuming that it takes place in a void.

What are their velocities, OP?

I meant, without accounting for the interaction of other reactants.
