Why Is Nuclear Fusion Difficult? On Earth it is very difficult to start nuclear fusion reactions that release more energy than is needed to start the reaction. The reason is that fusion reactions only happen at high temperature and pressure, like in the Sun, because both nuclei have a positive charge, and positive repels positive.
Are There Any Fission Stars? Star fission is the splitting of a star at a critical angular momentum, or period in its history, with the consequence of zero-age contact in the resultant binary star Do stars have nuclear fission? Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium. The production
What Are The Similarities And Differences Between Fission And Fusion? Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of
