Universe Inflation Bubble

excerpt from the post:

In looking at the inflationary many universe theory as put forth by several well known astrophysicists, such as Alan Guth and Michio Kaku. Also discussed by Neil deGrasse Tyson. My question has to do with inflation theory and our universe sitting on the skin of the bubble.

I have some confusion as to the point of reference of the “skin” of the bubble. I have read a lot of what has been written on this concept, but I am unable to decipher the answer.

I am a bit confused about the context when they say “skin of the bubble” and the math is beyond me.

I am trying to determine when they discuss that “we may be on the skin of a bubble”, (When talking 11 dimensions, I am not sure this is the proper phraseology.) are they saying the skin on inside of the bubble, or the outside? If we are on the outside of the bubble, then our perception must be limited to the bubble itself, not the "outside" or we might be able to detect other bubbles, or perhaps we are trying and just not yet succeeding?

If there may be many bubbles, it seems to make more sense that we are on the interior of the skin (again, the multi dimension aspect causes difficulty discussing this in 3 or 4 dimensional phraseology.) rather than on the exterior.

So is the spacetime we are experiencing on the skin inside of the bubble or the outside?

my comment:

Of course they must use the image of a bubble. The bubble is a deliberate deception because Earth is NOT on the bubble being suggested.
Earth is at the exact center of the claimed inflation so it cannot be on the bubble.
If they used a real image of the data the mistake is immediately obvious.

The hydrogen absorption line from hydrogen atoms in intergalactic space increases its red shift proportional to distance due to the low density of hydrogen in space. This red shift is not a velocity but it is treated as one.

If one tries to create a sphere for the trajectories of every object beyond our Local Group, every object is moving exactly away from Earth. There are none with any transverse motion.

This sphere puts Earth exactly at the center of the expanding universe.

Using a bubble for a layman's description obscures that conclusion accepted by cosmologists.
