Hi James,
First, let me thank you for your question ... I appreciate you taking the time.
'...how do you explain the interaction of matter with dark energy that caused dark energy to dominate some 6 billion years ago?'
'Dominate'?
How does the earth dominate plant life?
The earth facilitates plant life; it is the vehicle that plants use to exist ... the means by which they exist. The earth is the medium, the underlying structure which enables, facilitates, the existence of all plant life.
So too dark energy ... it is the underlying structure present throughout the universe, which facilitates all matter.
Rather than a relationship based upon dominance, I see one of symbiosis; interrelationships (interdependent relationships) between all things present within the universe - a mechanism of unimaginable diversity.
Matter, to my way of thinking, is a form of dark energy. Just like ice is a form of water. One way of looking at matter is that it springs forth from dark energy ... like a plant springs out of the earth.
Matter is a form of dark energy - dark energy, by its very nature, contains all of the ingredients necessary for matter's existence.
Ultimately, the greatest tool we have for understanding the universe is our thought process.
John
