An imaginative concept, which might help explain the expansion of the universe if the universe we experience were actually a living organism. However the premise is doubtful.

Even if it were true, how would it change your idea of how you shoudl live your life. Would you live it any differently and why? It woudl nto chang eyour life experience in any practical way.

To be realistic if your conjecture were somehow to be correct, then the type of information that we have been accruing about our galaxy and all the other galaxies in our observable universe would be so much different than what we have, as to be chalk and cheese. But hey, don't let me spoil a good imagination.
