Re: Expansion and the Movement of Light
Hi Bluejay,
​
If the expansion of the universe is slower than the speed of light, shouldn't it have been able to shave off at least a little bit of the transit time?
​
The space in between galaxies is expanding at a rate that is faster than light speed. That does not mean that the objects in space are traveling at a rate faster than lightspeed, in fact, they are barely moving at all - in comparison to (c).
​
That's why eventually we won't be able to see objects that we could once see, their light will not be able to reach us since the space between us and them, so to speak, is expanding at a rate faster than that of (c).
​
... as I understand it.

Hi GDR,
​
In an attempt to better help me understand it too, I'll try to answer this so if I get it wrong cavediver will be able to correct my understanding of it as well.
​
If then, we can look out into space and see things as they were 13 billion ago then what is left to have inflated beyond our ability to perceive?
​
What is left to "inflate beyond our ability to see it" is what we can currently see.
​
With time, billions of years of course, from our point in space, we will not be able to see anything more than the clusters near us. Everything else will be out of our "sight" due to the expansion rate being faster than light can travel.
​
... as I understand it.
