How Old is Sunlight Really? ☀️ The Mind-Blowing Journey of a Photon! | Space Facts

Did you know that the sunlight hitting your face right now is actually over 100,000 years old?
We are often told that it takes only 8 minutes for sunlight to reach Earth, but that is only half the story. In this video, discover the incredible journey of light particles called photons. Created deep within the Sun's core, these photons must fight their way through a mind-bogglingly dense solar interior. Because they constantly collide and bounce around, it takes them nearly 100,000 years just to reach the Sun's surface! Once they break free, they make the final trip to Earth in just 8 minutes.

That means the sunlight you are enjoying today was actually born when early humans were still living in caves!
