If the amount of Dark Energy in the Universe was reduced to lower than the amount of Dark Matter a phenomena called the Big Crunch will occur. The Universe would slow down its accelerated expansion and reverse. Black holes would engulf stars and eventually entire galaxies as everything contracted. As the shrinking increased in speed, black holes would swallow each other and the universe would end as an almost indefinitely tiny singularity, all matter squeezed into a small speck at the center of a black hole. A variation of this theory is called the Big Bounce. It includes the possibility that a Big Crunch would lead to another Big Bang, therefore creating a second universe. This theory opens up another important question. Are we the first, five hundredth, or the one trillionth universe? This question is explored in another article.
