Astronomers Detect First Split-Second of the Universe

After it started expanding you could observe it from inside.

 

Yes. But then since you are part of the expanding universe, it would not seem to be expanding faster than light. I thnk the difficulty in picturing this is that when you think of the universe expanding, you imagine that observable things like particles, etc. would be moving away from each other. The point that Scott brought up is that the yard stick you'd use to measure the distance between things would be expanding as well, at the rate that the universe was expanding, so your measurement would show no change.

 

Well, I think that's what Scott meant.
