Could dark matter particles the size of galaxies exist, or a anti-gravitational force field we call “dark energy” that might be getting stronger and denser, leading to a future in which atoms are ripped apart and time ends?
“We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of ‘negative gravity’, repelling all other material around them,” says Jamie Farnes from the Oxford University e-Research Center. “The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance, with both effects being simply explainable as positive mass matter surfing on a sea of negative masses.”
