I understand the basic analogy of looking at things from the past. Let me explain what I know before I ask about what I want to know.
The sun is 8 min light speed away. So whatever we see is the 8 min ago sun.
Similarly, If we see the star 1 light year far...we can say we are looking at the state of star one year before now.(may be the start is already dead at present :)
Ok. That seems logical.
But when I think of looking at the early stages of galaxy...looking at those clouds like things...they normally say...the further we look ...we are looking at the older image of the object...
Now my question...
when we look at those distant objects...our vision (what we see) also has to travel at certain speed?? or NOT??
How can a good telescope that can look far bring us more old images...
How do we see the image...do we follow them when they are traveling at the speed of light...
I know the question is quite vague...but believe me the question makes sense if you think clearly...
I would explode in pleasure if someone provided some insight!
Thanks
