quote:The observer—the person dropping the pennies—might conclude that space is moving away from him (expanding), or, he might conclude that the pennies (i.e. red-shifted galaxies) are falling toward a gravitational singularity.
And I'm saying that he could conclude both of those things, its not an either/or with the pennies.
Actually, that only holds true if there is but one penny falling, which is not what we observe looking at the universe.
The hypothetical observer might conclude that the penny is falling away from him or towards the center of the earth but that is simply semantics and irrelevant.
If the observer saw all of the pennies that were dropped he would see that all of the pennies were falling towards a single point and that they were all converging.
But what do we see when we look at the universe?
Anyone so limited that they can only spell a word one way is severely handicapped!
