Cómo funciona el Sol: Fusión y el efecto túnel

The video discusses the limitations of traditional fuels like gasoline and wood, which would deplete in a few thousand years. It explains how the sun, unlike these fuels, has been shining for 4500 million years due to nuclear reactions that fuse hydrogen into helium, releasing energy. The sun's mass is converted into sunlight, providing energy for billions of years. On Earth, achieving nuclear fusion is challenging as it requires heating hydrogen to extreme temperatures. The sun's energy is also attributed to quantum mechanics, which allows hydrogen atoms to fuse even at lower temperatures. This process keeps the sun energized, highlighting the importance of quantum mechanics in sustaining the sun's energy.
