Nuclear reactions are what really power our Sun and other stars, and it's pretty amazing when you think about it! Here’s a simple explanation:
Fusion Process: Stars mainly use a process called nuclear fusion. This is where lighter elements, like hydrogen, join together to make heavier elements, such as helium. This happens in super hot and high-pressure conditions.
Energy Release: When fusion happens, a tiny bit of mass turns into energy. This is based on Einstein’s famous idea, . This energy is what creates the light and warmth we get from the Sun.
Balance: The energy from fusion pushes outwards, balancing against the pull of gravity that tries to make the star collapse. This keeps the star stable and shining for billions of years.
Isn't it cool how the universe works?
