The journey of the Sun’s energy is a fascinating tale of time and distance. Deep within the Sun’s core, nuclear fusion generates immense energy as hydrogen atoms fuse into helium. This energy, in the form of photons, begins a slow and chaotic journey outward. Due to the extremely dense layers of the Sun’s interior, these photons are constantly absorbed and re-emitted by particles in a random walk a process that can take up to 17,000 years just to reach the surface of the Sun. Once this energy finally escapes into space from the surface, it travels at the speed of light and takes only 8 minutes and 20 seconds to reach Earth a stark contrast that highlights how slowly energy moves inside the Sun compared to the vast emptiness of space. So when we feel sunlight on our skin, we’re actually experiencing energy that began its journey thousands of years ago. #space #science #fact #facts
