We don't see that - everything is moving further apart.
(That some galaxies, under their local attraction, are getting closer is not a counter-example; examples of this are scattered about and don't indicate any common source).
Try drawing a picture of what you describe; it will help.

Why would things get closer together if everything is accelerating in that general direction?
Remember this thing would need to be super massive to effect our entire visible universe. If everything was accelerating at different speeds towards the source then things would get farther apart.
