-I learned that if you look at a star 10 million lightyears away, the light that you are looking at is 10 million years old since the photons have been traveling at the speed of light for 10 million years to reach you.
-I also learned that all EM radiation travels at the speed of light.
-I know that there is not faster than light, but object that move slower than light redshift and blueshift on the visible spectrum depending on which direction they are moving with respect to the observer.
I'm asking this question because if I'm putting the pieces together correctly, then the stuff we observe "now", really all happened tens, hundreds, thousands, millions, and billions of years ago. Correct? Which, would that mean that gamma ray bursts, xrays, radio waves--all limited by the speed of light--are all events that happened in the past, and that their EM radiation takes time to reach us in every situation?
