Does it take an infinite time to reach the center of a black hole?

No, from the frame of reference of the poor soul crossing the EH, he or she will reach the center and doom in a small finite time. From the frame of reference of a distant observer, that poor soul will simply be redshifted and eventually fade from view before crossing the EH, due to ever infinitely increasing time dilation.

It depends which theory is correct.

The BH does not stop time. It just slows it down a lot.
If we imagine that reality is a video with 1,000,000 frames per second, the BH puts the video in slow motion to (e.g.) 1 frame per second, seen from a distance!
A person being at the BH would not experience any difference.

Tidying that hurried response up some, the distant observer, never sees the poor soul cross the horizon.

Is a Black Hole event horizon experimentally proven to exist?  Isn't it rather a mathematical construct?   Is anything experimentally shown concerning black holes? (other then it's existence, size/gravity)

Hawking's theory shows an Apparent horizon....

The only doubt is concerning the "nature" of the EH, and quantum effects. That does not invalidate the BH and the effects we see, and of course the recent discoveries of gravitational radiation emerging from bionary BH collisions.
