We explore the consequences that follow if the dark energy is phantom
energy, in which the sum of the pressure and energy density is
negative. The positive phantom-energy density becomes infinite in
finite time, overcoming all other forms of matter, such that the
gravitational repulsion rapidly brings our brief epoch of cosmic
structure to a close. The phantom energy rips apart the Milky Way,
solar system, Earth, and ultimately the molecules, atoms, nuclei, and
nucleons of which we are composed, before the death of the Universe in
a “big rip.”
