Is this concept of Non-self correct?
"Monks, I will teach you the All. Listen &amp; pay close attention. I will
  speak."
  
  "As you say, lord," the monks responded.
  
  The Blessed One said, "What is the All? Simply the eye &amp; forms, ear &amp;
  sounds, nose &amp; aromas, tongue &amp; flavors, body &amp; tactile sensations,
  intellect &amp; ideas. This, monks, is called the All. [1] Anyone who
  would say, 'Repudiating this All, I will describe another,' if
  questioned on what exactly might be the grounds for his statement,
  would be unable to explain, and furthermore, would be put to grief.
  Why? Because it lies beyond range."
  - Sabba Sutta


Universe is a concept. What you call universe in reality is just eye &amp; forms, ear &amp; sounds etc. etc.

So the eye &amp; forms are not-self, ear and sounds are not-self...
This idea you have been contemplating represents(in reality) just the mind and thoughts which are also not-self.
