Have you ever considered that the Universe isn't actually expanding, but instead, we're just shrinking?

When you're caught inside of a black hole, everything outside of the event horizon has the appearance of moving away faster than the speed of light. Everything "falling" in with you will appear normal, including time dilation and velocity. But the further away objects are from you, the more they will provide the impression of speeding away.

The Universe is not expanding. We're just compressing.

On to the next question:

A scientist is measuring the doppler effect of the outermost reaches of his Universe. He notices that the galaxies that are the furthest away are accelerating away at rates faster than the speed of light, in addition to accelerating away from the galaxy he resides in.

He concludes that the Universe is expanding, and therefore, the Big Bang theory has been verified.

Has this scientist made any errors in his reasoning?
(A helpful hint: At the center of his galaxy, there is a Black Hole which has been compressing nearby matter into a singularity. How might the universe appear to someone being compressed into a black hole?)

Keep in mind this is just a thought experiment.
