When hydrogen stocks run out
Nuclear fusion is the process that powers stars, such as our sun.
Fusion occurs in the core of the sun and other stars.
No. A white dwarf is the remnant of a star in which fusion as stopped.
In the cores of stars and hydrogen bombs.
Because the conditions of temperature and pressure that occur in stars do not occur on earth
In all stars, the fusion only occurs in the inner core.
Natural nuclear fusion reactions occur in all stars
The cause is the very high temperature.
The fusion of Hydrogen into Helium causes heat and radiation to occur.
In stars. As far as I know this is the only place.
Not typically. When a star burns it starts with fusion of Hydrogen. Later heavier atoms are formed, also by fusion. It is believed that the very heavy atoms, that release energy when split (fission) are only formed by very massive stars . These atoms are also formed by fusion. When one of these very massive stars explodes (super nova) it spews out its atoms and during this process its possible some fission will occur, but for the most part star evolution is a fusion story.
Yes, stars are fusion reactors.
