The evidence points to "no",  dark energy will tend to lead to an acceleration in expansion, and "big cooling" (if that means what I think it means)

*"Dark matter and dark energy are in balance with each other"*. No. If they were in balance the expansion wouldn't be accelerating. There is no evidence or accepted theoretical possibility of a future contraction phase.

I wager it's anyone's guess now and it's not likely to quickly change.
