  • In that sense, the first title means a new idea of what a universe is, whereas the second means a new idea of the universe we live in. The same definitions apply that I mention in my answer below.

  • Based on English language links I've seen for this book and the description of the book itself, I'd say "A New Concept of the Universe" is the correct title.

From merriam-webster.com:

1 : something conceived in the mind : thought, notion

2 : an abstract or generic idea generalized from particular instances

"Concept of the universe" uses the first definition and "concept of universe" uses the second.

Here are a couple of example usages:

In my astrophysics class, we studied the concept of universe.

In other words, we studied the abstract idea "universe".

When I realized how small I was, I had a better concept of the universe.

In other words, I had a better thought or notion of what the universe was.


Concept of Universe

The Universe itself is a concept.

Concept of the Universe

The Universe has a concept about something.
