Part 5<quoted text>As you pointed out, all three are solved by an inflationary stage. This also leaves a record on the background radiation, which has been observed.
And your point is?
Or will we?
In this case, the gravitational forces must act upon the furthest light waves and slow them down little by little until...
We can imagine at some point the exact moment when the light waves reach their zenith where their outward force exactly matches the gravitational pull. In other words, light is stopped altogether. I'm sure Einstein would've loved to try to consider what this scenario should be like. Maybe he did. I'm not sure.
The most realistic way around this bizarre scenario is to imagine that the pull is not precise and simply turns the light wave in a large slowing arc until they head back in the other direction.
This case creates a possible scenario where if we place ourselves in the right place at the right time (In the light waves path on their return trip) It would be possible to look forward any observe the universe forming behind us. Of course we couldn't turn around and watch the crunch at the same time since the gravity would presumably pull all tell tale light back into itself. Again, this is a very strange effect to imagine.
In either case it is hard to imagine the situation of a gravity so strong that ALL light photons would eventually be stopped before reversing course or arcing back to the beginning. This is not to say that this can't happen, but on a universe wide scale this would indeed be an interesting phenomenon to work out.
Issue #5: Problem of the edge
Another problem with an expanding universe theory is the presupposition that an edge to the universe must exist.
We have already shown that the empty space ahead of all matter exists in the universe as well, so what is at the edge of the universe? Let's look at it logically.
Let us imagine the edge of all space and time as a barrier of some kind. An impenetrable barrier enclosing all space, both empty and occupied through which matter and time can not pass. The edge of the universe must be something of this nature, right?
Any barrier, no matter what shape, size, composition, thickness, etc. always has two important sides: The side holding the contents and the opposite side, which is furthest away from the contents. Both sides always have a defined edge and therefore something on the other side of each edge. In this theoretical case, one edge touches the universe.
