Abstract

The discovery that most of the energy density in the universe is stored in the form of dark energy has profound consequences for our future. In particular our current limited understanding of quantum theory of gravity indicates that some time in the future our universe will undergo a phase transition that will destroy us and everything else around us instantaneously. However the laws of gravity also suggest a way out -- some of our descendants could survive this catastrophe by riding gravity away from the danger. In this essay I describe the tale of this escape from doomsday.

    • ... which is expanding. So now you have a percolation problem: what grows faster, the bubbles or the universe? The latter is also thought to be expanding at an accelerating rate, which leads to funny scenarios like this: https://arxiv.org/abs/1503.08130
