The following is copied from a piece of science news introducing
dark energy:
The proposed dark energy, would inhabit empty space and would
be evenly distributed throughout the universe. Moreover, dark
energy would exert a repulsive force-what might be called antigravity.
More accurately, dark energy would be the flip side of ordinary
gravity because it would possess a strange property called
negative pressure. Something with negative pressure resists being
stretched, as a coiled spring does: Pu
