The topic of dark matter and dark energy has been unraveling for years, as 95% of the universe is made up of the unknown, invisible material that astrophysicists are not able to fully understand.
In a new study from astrophysicist, Jamie Farnes, from Oxford’s e-Research Centre at the University of Oxford and published in Astronomy and Astrophysics, there may be a modification to Einstein’s theory of general relativity, bringing both dark matter and dark energy into one fluid, negative mass.
Farnes explains that even though dark matter is invisible, it employs a gravitational force on nearby matter that can then be measured. Dark energy on the other hand is a repulsive force that counteracts gravity and makes the universe expand at a much greater rate.
