No. The laws of physics do not permit detection of motion in raging
pink fairy Universes.

Yeah, I want what he is smoking.

no.
No material object can travel at c or -c wrt any other material
object.
Blue and red shifted light from other galaxies simply tells us the
relative velocity of the two objects to each other.
Try asking what the limit is for red shift and blue shift as the
relative velocities of two objects approach c or -c.
The limit for red shift of objects moving away at relative speeds
approaching c is zero i.e. all frequencies from the object approach a
frequency of zero.
The limit for blue shift of objects moving towards us at relative
speeds approaching c is infinite i.e all frequencies of light from the
object approach infinity.

Are you able to carry on reasonable conversations of a technical or
scientific nature face-to-face with other humans?

Look up "universe" in a dictionary. Probably a better scientific
definition for universe is everything to which we are causally
connected. Our observable universe extends back in time to about
13.7 billion years.

This should keep you busy for a while:
