Cosmic inflation did probably occur before the Big Bang. In the eternally inflating cosmos model there is the idea that dark energy that is causing the universe to expand at an accelerating rate is part of an yet to be understood inflaton field. As the rate of inflation in our universe continues to grow, here is a simple question, what happens if the rate of universal expansion exceeds the rate at which light travels. If there is no upper bound to the rate of inflation then at some point no only will normal matter be torn apart but also imagine what happens to a black hole. There are several types of boundaries to the universe. The particle horizon, which is the boundary of the known universe, starts at the CMB (cosmic microwave background.) We know that this is currently viewed as about 46 billion light years from our position is space. But if were to launch a space ship and travel at the speed of light we could never reach the currently known particle horizon. As we travel through space to our destination space is still expanding. This is known as the cosmic event horizon, our best estimate is that this value is currently about 16 billion light years away. However that value shrinks at the rate of inflation increases, long after the big rip destroys all baryon matter around us the only objects that would still exists would be black holes. As the rate of inflation continues to increase eventually the particle horizon and the cosmic horizon approach the boundary of the event horizon of the black hole, and then at some point that rate of expansion exceeds it. This would not immediately result in the black hole tearing itself apart, the rate of inflation still needs to exceed the limit of the gravity. Eventually there will come a point where the rate of inflation hits a tipping point where the singularity is torn apart. As the rate of expansion initially exceeds the speed of light matter a new universe is born as a new dimension of time starts in the new region of space. This new chronology would process similar to our universe but may have different physics. We have no way of knowing at this point.
