Yes, but remember this thread is about sutta support.

Yes, that's obvious by mundane observation. We don't need a sutta to tell us that...
Another aspect of momentariness (in Theravada at least) is that there is only consciousness of one object at at a time. Are there suttas that make that statement clearly.
