A New Theory Says Dark Energy and Dark Matter Might Be the Same Weird Substance

In December, Dr. Jamie Farnes of the University of Oxford in England published a theory that may get us closer to that goal. It says that the invisible portion of the universe is made up of not dark matter and dark energy, but one "dark fluid." This fluid has two key characteristics. One is that it possesses negative mass — while the regular mass of stars and planets exerts a gravitational pull that attracts other objects, something with negative mass would exert a gravitational push. If you were to throw a negative-mass bowling ball, it would roll toward you instead of away from you. Negative mass isn't a new idea, but previous research had ruled it out as an explanation because, while the force of dark energy has remained constant over time, a negative-mass substance would thin out as the universe expands.
