Why Does Light Redshift When Space Expands? Have you ever wondered why light from distant galaxies appears shifted toward the red end of the spectrum? In this engaging video, we'll explain the science behind why light redshifts when space expands. We'll start by discussing how light travels as waves with specific wavelengths called wavelengths and how these wavelengths change as galaxies move away from us. We'll explore the concept of the universe's expansion and how stretching space affects the light traveling through it. You'll learn how this phenomenon differs from the Doppler effect and why it is considered direct evidence of the universe's ongoing growth. We'll also cover how scientists measure redshift and use it to determine the distance and speed of galaxies. Additionally, we'll explain the importance of redshift in supporting the Big Bang theory and studying dark energy, the mysterious force accelerating the universe's expansion. Discover how advanced telescopes like the James Webb Space Telescope utilize redshift data to look back in time and understand our universe's history. Whether you're a space enthusiast or simply curious about cosmology, this video will help you grasp why the stretching of space causes light to shift toward red, revealing the dynamic nature of our universe.
