Do we see things different?

Well - of COURSE - in your reality - those galaxies are moving too fast to see - - all you have to do is bennnnddddd linear space through a tesseract - then you can capture it with a Lytro Light Field SensorUnlike you, I have not yet taken pictures of the most remote galaxies.

Though those outer galaxies may approach the speed of light, nothing prevents another one from going faster as long as it doesn't exceed the speed of light.

What you say I know, but you have not answered my question. If the galaxies that crowd against the outer perimeter are the reddest, it implies that there are others that are beyond that range, but we could never have particulate evidence of their existence, because they are outrunning the speed of light. If you do not accept this postulation, then what happens to all the galaxies once they pass this sort of event horizon, do they cease to exist?

I've actually never heard the concept of an event horizon at the perceived edge of the universe, only at the edge of a black hole. Maybe I don't really understand the concept. It seems to me that the ones further out would be the reddest and define the outer perimeter.

I coined the term myself, because it acts like one. Up to the line, namely the outermost part of the Universe, galaxies appear the reddest. Beyond the line we see nothing. It is like the event horizon of a black hole.
Seeing nothing beyond a certain "horizon" implies one of the two following conclusions:
1. The Universe ends at that spot.
2. In light of the red shift, there are other galaxies beyond that spot, but we cannot know about them because that is the point where they outrun the light they emit.
The second conclusion is more reasonable, because the outermost galaxies are already running away from us close to the speed of light. It is logical to hypothesize even more remote galaxies beyond them. Perhaps Einstein's speed limit applies only to mater and its particulate components, but not to space, which may be composed of building blocks smaller than quarks.

It may be one of those things that cosmologists just accept, like some accept Superstring Theory. They say "I don't claim to understand it, I just accept it." I'll tell you what though, there is no better way to stretch your mind and keep your brain young than to ponder either cosmology or quantum mechanics. I wish my higher math skills were better but I don't have the patience.

Re: your last post, hmmm. The Superstringers have talked about entire universes wound up into infinitely small spaces.

The best art of any flavor always comes from those in emotional pain. Look at the history books.

Past the edge of the galaxy should be the zone of the original expansion, which is widely accepted as a faster than light speed event. This would make it impossible to see, but it is the reason we have (and have measured) uniform radiation throughout the galaxy. As to event horizons, were this idea true, what would it be like, accelerating past Einstein's Theory?

I use the term event horizon, because though for different, even opposite reasons, the effect is the same: no events can be discerned from that point. The black hole creates an event horizon because it stops light. The most remote galaxies, if they exist beyond the ones we can see, create an event horizon by receding too fast for their light ever to reach us.
Past Einstein's speed limit? That sounds very heretical for a mere historian like me, therefore let us just postulate two different kinds of velocity. Independent velocity is the change in time/space that any matter or particle can acquire vis a vis the space in which it is contained. Let extended velocity be the change in space/time that same matter or particles are capable of while being transported by space. Perhaps that can violate the original speed limit. Einstein spoke of general and special relativity, so let us postulate general and special speed limits for the Universe.
And now that we are at it, have you pondered of what space is composed? It cannot be nothing, obviously, or it could not interact with matter and its constituent particles. So what really is space?

How did my question about seeing things different turn into this? Maybe a new thread should be started.

But that is what is so unique about UHH. You never know where a thread will go, and it is ever so interesting.

It's better on this one. This been a scientific conversation. Usually it's a dual about lies and truthful politics things. Those who tell the lies draw first to shoot you down because they can't hold a conversation for long.

Transmogrification - - this ALWAYS happens when you ask a perceptual question versus one that needs a techie answer. The perceptual universe bends away from the seed thread - sometimes faster than the speed of light as discussed above - via Fractal geometry until the end appears as the obverse statement. Why else would the Earth rotate with a period of 24 hours ???How did my question about seeing things different turn into this?
