Reply to comment by dphseven in Why do cosmologists say that gravity should "slow down" the expansion of the universe? by crazunggoy47

Not quite because as I noted, dark energy supplies gravitational repulsion. In the big rip, the energy density of dark energy increases over time, and so does the repulsive force. That is what rips everything apart.

(Observations currently do not support that the energy density of dark energy is increasing.)
