We know so little of halo nuclei. Also, the future of fusion lies ahead. We've built many different types of reactors to date, but none has been successful in achieving a self-sustaining reaction. When we do achieve it, the use of fusion for energy could solve many energy problems. Pioneers in the field continue to make the trek down the road to fusion, and to achieve the goal, the future needs what this generation has to offer.
Many answers lie ahead, waiting to be discovered.
