In the balloon model:

All the galaxies get bigger as the balloon expands, the galaxies expand along with “space”.

All the galaxies are flat and curved in two dimensions like an inverted dinner plate.

All galaxies move apart at the same rate.

All the galaxies are the same age.

Light curves as it moves from galaxy to galaxy, and if it goes far enough, it returns to its point of origin.

The viewer is out in 3-D space looking at the surface of an expanding sphere.

The third D of our universal space is left out of the galaxies and the universe.

All beings in the galaxies would have to be flat and could not have round eyes.

The center of the balloon is inside the 3-D balloon, but all the galaxies are on the 2-D skin of the balloon.

Our universe does not look like the expanding 2-D surface of a balloon.

Our galaxies are not dots of black ink made on the spherical surface of a white rubber balloon.


Observation from our vantage point:

We are not on a curved “surface” of the universe looking “around”, we are at some point inside it looking out in three directions, not looking around it in just two directions.

There is no evidence the galaxies are “expanding”.

There is no evidence that the galaxies are flat or are shaped like dinner plates. The galaxies are 3-D just like the universe is, just like we are.

We have round eyes, not flat ones.

We see a 3-D universe, with the galaxies moving away from each other in 3-D space, not in “curved” 2-D space.

There is no evidence that all light beams are curved or that they always return to their point of origin.

The galaxies are points or blobs of glowing light. They aren’t dots made on rubber with a black magic marker.
