Hi, I have a question about the redshift caused by the expanding universe. I am not a physicist and reading books and articles about physics is just a hobby so I apology if this is obvious to most of you. I have read somewhere that the light from far away galaxies is redder than light from nearer galaxies. Why is this? I understand that the redshift is caused by the expanding universe stretching the light but wouldn't the amount of redshift only depend on how long ago the light was emitted? I would have thought that two event happening at the same time would have the same redshift because the universe has expanded by the same amount for both events.
