Whether DarK Energy

In brief quick summation of a recent conference on Dark Energy, including Reiss, Randall, Freedman, etc. releases appx. Feb. 24-5, 2019.

Trying to gauge the influence of Dark Energy on the Cosmos:

.Some force started expansion in the first trillionths of a second after the "Big Bang"

.Around the first 100,000 years after the cosmos's inception a repulsive energy came to being and worked to the fore, accelerating expansion of the universe and about 100,000 years after that it appears to have ceased.

.Some 6 billion years ago Dark Energy gained domination of forces and has been accelerating since

.Is Dark Energy accelerating at a constant speed or does that vary?

.Does Dark Energy turn off and on at times?

.Will Dark Energy grow denser and stronger and force a rip of the cosmos? At less than w<-1 equation of state, will Dark Energy break the dominant energy condition, dominate everywhere and be unstable? Turn phantom?
