Question
Which is the origin of the sun's energy
Answers
GPT-4o mini
The energy of the Sun originates from a process called nuclear fusion. In the Sun's core, hydrogen nuclei (protons) collide at extremely high temperatures and pressures (about 15 million degrees Celsius or 27 million degrees Fahrenheit). Under these conditions, the protons can overcome their electrostatic repulsion and fuse together to form helium nuclei.
During this fusion process, a small amount of mass is converted into energy, as described by Einstein's famous equation \(E=mc^2\). This energy is released in the form of gamma rays and later converted into other forms of radiation as it makes its way to the Sun's surface and then radiates out into space as sunlight.
This process not only powers the Sun but also sustains its luminosity for billions of years, contributing to the energy that supports life on Earth.
