How light reveals that our universe is constantly expanding
In short: We often think of the universe as a static void, but it is actually in a state of constant growth. This video explains how astronomers use red shift to prove this expansion.
Red shift serves as primary evidence for the fact that the universe is expanding all the time. By observing how light changes as it travels across vast distances, scientists can determine the movement and scale of the cosmos.
The video provides a visual exploration of these astrophysical principles, making it an ideal resource for understanding the mechanics of cosmic expansion.
