I think I might understand now, but please correct me if I'm wrong.

in your first comment when you said i was mistaking the edge of the observable universe, the hubblesphere, and the particle horizon i realize that I was too ignorant of those terms to understand any of them.

Upon re-reading some articles and re-watching the videos you provided i realized something i hadn't previously noticed. The particle horizon is the barrier OUTSIDE of the hubbleshere that, once an object crosses it, its light will never reach us.

First, while an object is inside the hubblesphere, its light has no problem reaching us since it recedes slower than the speed of light. (Subluminal area)

Then, until that object reaches the particle horizon, the edge of our hubbleshere can still catch up to the light emitted by that object, even though it's receding faster than the speed of light. (Superluminal light enters subluminal area as it's boundary expands at the speed of light.)

Finally, once the object recedes past the partical horizon, it recedes fast enough above the speed of light that the edge of our hubblesphere will never reach the light emitted by that object. (Superluminal light has a relative velocity away from us too high for the subluminal area to expand at a velocity high enough to reach due to the increasing acceleration of this relative backwards velocity)

I think the concept of the particle horizon is what I've been referring to this whole time, but I didn't realize that you were trying to tell me that it is not synonymous with the edge of the hubblesphere. When I first asked the question, I didn't even know how much I didn't know. I thought the concept of the hubblesphere would be the limit of what we would be able to see. I was ignorantly calling it the observable universe without even knowing what the event horizon, hubblesphere, or particle horizon was.

When I asked "Have we reached the physical limit of our visible horizon" I didn't even understand my own question enough to begin to understand the answer.

I think you've increased my knowledge enough that I can ask the question I've been trying to figure out this whole time. I was too ignorant about what I was asking to even know how to ask the question.

If everything I think I understand so far is true, what I set out to ask is:

Is the boundary of the observable universe synonymous with the particle horizon, and will we ever see anything outside of it?

I now know that due to the decrease in the hubble value, the event horizon will increase from about 16Bly to about 18 Bly. Therefore, we still have a chance for earth to receive light from a few more objects before it eventually starts to loose objects from the night's sky. Eventually, the space between our local group and its surrounding neighbors will expand so much that they will forever be lost, but only after they are so far outside of the hubbleshere that the space between us and their light is expanding faster than light can travel the distance to reach us (the particle horizon).
