There are four forces in the Universe: strong, weak, electromagnetic and gravity. You may be most familiar with gravity. Gravity is what holds you and your dog to the surface of this planet! The other

When the temperature in the core of a star is really hot (100 million degrees Kelvin!) fusion of Helium into Carbon happens. Oxygen is also formed when the temperature is this high. When it gets even hotter

A plot of the binding energy per nucleon vs. atomic mass shows a peak atomic number 56 (Iron). Elements with atomic mass less then 56 release energy if formed as a result of a fusion reaction. Above this

Nuclear fusion has been achieved in a controlled manner (that means no bombs are involved!!). Right now, these fusion experiments take in more energy than they produce. So they can't be used right now

In the Hydrogen bomb, an explosion takes place so that the temperature and density is right for fusion to occur. This fusion results in a sudden release of energy that produces an even bigger explosion.

All of the matter and energy in the Universe was initially found in a very small space. An explosion happened which caused the Universe to begin expanding.

The neutrino is an extremely light particle. (You definitely couldn't weigh one on your bathroom scale!) It also has no electric charge. Fusion reactions in the Sun produce neutrinos. By detecting these
