: '''Nuclear fusion''' is possible in [[laboratory|laboratories]] on [[Earth]] but it cannot be sustained for long periods of [[time]] to produce enough [[energy]] to be useful as an [[Energy Resource|energy resource]].
: '''Nuclear fusion''' in [[laboratory|laboratories]] on [[Earth]] must be done at much higher [[temperature]] than in the centre of [[Star]]s because the centre of [[Star]]s is a much higher [[pressure]] so [[Atomic Nucleus|nuclei]] collide more often.

This is the most common pathway for [[Nuclear Fusion|nuclear fusion]] in [[Star]]s as the [[neutron]] goes on to be captured by a [[Hydrogen]] [[Atomic Nucleus|nucleus]] to become [[Deuterium]] or captured by a [[Deuterium]] [[Atomic Nucleus|nucleus]] to become a [[Tritium]] [[Atomic Nucleus|nucleus]].
