Take your statements about time and rewrite them naming another physical dimension. Say for example height.

Does the statement:
"Height doesn't really seem to be a constant in the universe, maybe height is something that works fine on a small scale (relatively) such as our earth, but not in the universe?"

Nonsense. Perhaps it would make more sense if you sustituted "Length" or "Width"? No. Not with them either. Time is just a dimension. Nothing more ... nothing less. Thus your statement is should be reconsidered.
