Scientists at the University of Oxford may have solved one of the biggest questions which linger in modern physics.
Unifying dark matter and dark energy
They did this with a paper that’s unifying dark matter and dark energy into a single phenomenon.
It’s a fluid which has negative mass. If you were to push a negative mass, it would accelerate towards you, and this new theory may also prove that a prediction made by Einstein 100 years ago is right.
The current model of the Universe which has been recognized so far is called LambdaCDM, and it doesn’t tell us anything about what dark matter and dark energy are like physically. We only know about these because of the gravitational effects that they have on other observable matter.
The new model has just been published in Astronomy and Astrophysics, by Dr. Jamie Farnes from the Oxford e-Research Centre.
It offers a new explanation. Dr. Farnes says: “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. Although this matter is peculiar to us, it suggests that our cosmos is symmetrical in both positive and negative qualities.”
The negative matter was previously ruled out
It’s also interesting to note that the existence of negative matter has been previously ruled out because it was believed that this material would become less dense as the Universe expands which is contrary to the observations that show dark energy doesn’t get thinner over time.
Dr. Farnes says: “Previous approaches to combining dark energy and dark matter have attempted to modify Einstein’s theory of general relativity, which has turned out to be incredibly challenging.”
This new approach brings a new outcome.
“The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance.”

Rada attended the courses in the Faculty of Letters, Romanian-English section, and finished the Faculty of Theatre and Television, Theatrical Journalism section, both within the framework of Babeş-Bolyai University of Cluj-Napoca. Up till now, she reviewed books, movies, and theatre-plays, enjoying subjects from the cultural niche. Her experience in writing also intersects the IT niche, given the fact that she worked as a content editor for firms that produce software for mobile devices. She is collaborating with online advertising agencies, writing articles for several websites and blogs.
