I find your article reference fascinating, as it has come up in my thoughts more than once; and it is obvious to most thinkers, that the even horizon is the VISIBLE event horizon not necessarily the edge of the universe that was borne out of the big bang.

I just have one question: how would the mass accelerating away from us and outside of the visible world act as negative gravity, i.e. a pushing out force while it is actually a pulling force?

I can only see that happen as the mass of the matter from our bing bang already outside of our visible space, is pulling the visible space apart. This is fine, this makes sense. But what made the "outside" by us invisible mass accelerate outwardly? If it was pushed out at a great speed by the initial force of the big bang, then it ought to be further away than it could have an effect on us by classical understanding of gravity.

Think about it, with only four things in mind: 1. the highest attainable speed is the speed of light, 2. the age of the universe counting back to the big bang is older than the conventionally thought 14-point-something billion years 3. whatever is speeding away from us at light speed, can't be seen by us, and 4. The diameter of our seen universe is 14 billion years. I also assume that the outer layer is not pulled outward by some outer-outer layer of mass.

Given the restrictions in the above, we must conclude that the outer layer started to speed away at light speed from the big bang material right off the bat. Then adding the fact that the universe is 14+X billion years old, the outer layer has to be 14+X billion light years away from us.

This outer layer could be so far away, that its gravitational pull would be negligible. In fact, this outer layer is 14 Billion light years plus X billion light years more away (depending on the size of X) from the centre of the universe, the location of the big bang.

Because the average speed at which the KNOWN outer layer (the event horizon) has been travelling away from the point of the big bang, is half a light year per year. It started at zero displacement, it attained 7 billion light years distance in 14 billion (or 14 + X billion) years, so the average speed of the outer layer is 7 billion light year per fourteen billion years, that is, half a light year per year. The "outer layer" has started off at light speed, so it is 14 billion light years away. If the universe is older, then it's (14 plus X) billion light years away where X is the extra age of the universe.

This means that they "outer layer" of invisble mass is at least 7 billion light years away form the event horizon.

This is such a great distance, that the outer layer has a snowball's chance in the centre of the Sun to have any effect on our universe by gravity.

That can only be negated by the fact if the outer layer has incredibly, inhumanly huge mass. if you do the calculations, you can actually calculate the size of this mass, form the equation

F=(M1+M2)/D^2

Where F is the gravitational force,

M1 is the mass of the event horizon's applicable part

M2 is the mass of the outer layer

and D is the distance of the outer layer from the event horizon.

I only know the D, from the above, which is 7 billion light years.

For F to be large enough to have a pulling effect the size it is, then EACH PORTION of M1 has to be way larger than roughly 5.0 times 10^19 Kg. By portion I mean the section in the sphere of the outer layer that is closest to a section in the sphere of the event horizon, which have a gravitational pull effect on each other.

I am sure I have made a mistake in the calculation. That goes without saying, because my equaltion of gravitational force is false; it needs a constant multiplier, which I long ago have forgotten. So the 5x10^19 Kg is most likely a child-like estimate compared to the real value, when one also considers the gravitational coefficient in the equation.

Aside from that, I was unable to define "section" more precisely.

So while my math is way out of kilter, it is also rather meaningless. All I wished to show with it, is that the outer layer, which is invisible, is at least 7 billion light years more away from our event horizon, and as such, it must have an enormous mass (which is nevertheless not impossible) to exert a pulling effect on our known, visible universe.
