I Exponential expansion and the Cosmological Constant

[Ranku]

The universe will expand exponentially when dark energy completely dominates the energy density of the universe. To clarify, does that make the present expansion 'quasi-exponential'?

 

[Orodruin]

Unless you define what you mean by "quasi-exponential" the question lacks meaning.

In the sense of tending toward being eventually exponential.

 

[Bandersnatch]

With that definition, your question reads: 'The universe tends towards exponential expansion. Does that make the present expansion tend towards exponential expansion?'
I.e. it's tautologically true.

I don't know. Sounds a bit tautological to me ...

At present dark energy is approximately 70% of the universe. Dominates?

You just can't go wrong with a tautology.
