What does a high red-shift in the light from nebulae indicate?
High recession velocities
Presence of foreign life forms
Stellar formation patterns
Close proximity to Earth
Answer
High red-shift in the light from nebulae indicates high recession velocities. This is because as an object moves away from us, the wavelength of the light it emits is stretched, causing it to appear redder. This is known as the Doppler effect. The greater the recession velocity, the greater the red-shift.
