The big Rip

This post is from my own research during my study at BAU, it is about how will the universe ends.

The first theory claims the Universe will end with a Big Rip, as the pull of the Universe's expansion gets stronger than the gravity it contains. This would tear apart galaxies, followed by black holes, stars and even our own planet.

Earth, and humanity with it, could slowly decay into radiation, collapse in on itself or be ripped apart as the Universe's expansion ramps up. This would leave the Universe full of single, disconnected particles.

Until around five billion years ago, the Universe's growth was slow due to its strong gravitational pull. More recently, this expansion increased, with many attributing it to the effects of dark energy. For a Big Rip to occur, dark energy must win in its battle with gravity to such a point that it can rip apart individual atoms.

Last year, Marcelo Disconzi, assistant professor of mathematics at Vanderbilt University in Tennessee, in collaboration with physics professors Thomas Kephart and Robert Scherrer, devised a new mathematical model for the Big Rip.

This model suggests that the expansion of the Universe will eventually become infinite. Previous models largely ignored viscosity, but in Disconzi's hypothesis, it is viscosity of the Universe that drives its violent destruction. His theory is based on proposals made by French mathematician André Lichnerowicz in the 50s.
