I just read about the discovery of a young black hole. It sems that in 1979 an amateur astronomy buff noticed a super nova and subsequent observations seem to show that a black hole was created there. I was wondering what observations would be seen from this point on. I understand that the environment of the black hole will dictate the specifics, but is there a model for what to look for in the future from this object?

Martin: Thanks for the answers. You are right I was using the term incorrectly. According the the Princeton article the edge of the observable universe is like an event horizon. It follows that the Andromeda Galaxy would have a different event horizon so would be able to see light from objects that we could not see. That makes my question: If someone leaves the earth and travels in one direction at C would the event horizon they can see be different from what we can see from here or would thay have to travel at multiples of C?? Still trying to wrap my mind around some of this stuff. My thought is that you would have to be at multiples of C or you would just be maintaining the current event horizon.

Hello folks. This is my first post here but have been reading for a while. I've followed most of what has been said ( my degree is in Bio back in 1974) but have three questions. 1. If space is expanding why does the space between the local stars not increase? Is the gravity of objects so far apart able to counteract the expansion?? 2. If the observable universe is approx 45 Billion LY, how much larger is the TOTAL universe? I think that someone on this thread said that we couldn't know. Shouldn't it be able to be calculated from the CBR?? 3. If our galaxy and the Andromeda galaxy have different Hubble radii, does it follow that if someone leaves earth at C and travels say 100 years would their Hubble radius be different? Or would they have to be traveling faster than C?? Thanks to anyone who can clear this up for me. Interesting place !!
