Introduction:
Stars release energy, so they must have a source of potential energy. We find this potential energy turning to radiant energy, as gravity fuses hydrogen into helium.

Conclusion:
Fusion is the process of squeezing nuclei together. When they fuse into a single nucleus, energy is released. We see gravity do this in the sun; we have made Hydrogen bombs; we hope that lasers will be able to fuse hydrogen for commercial power plants.
