Our universe doesn’t make sense, a scientist has admitted: it’s spreading out at a speed
which it really shouldn’t, and our best theories can only explain 5% of it.
So what about the other 95%?
It could be a ‘dark fluid’ a University of Oxford expert has claimed, a strange material which repels other matter.
The idea would solve two mysteries: why galaxies hold together, and why the universe is expanding at an accelerating pace.
The mysterious ‘dark fluid’ would replace our two current theories: ‘dark matter’ (invisible matter which holds everything together) and ‘dark energy’, a phenomenon accelerating the matter in the universe outwards.
Instead, Jamie Farnes suggests, we could be surrounded by a soup of dark fluid, which has
negative mass (repelling stuff around it, rather than attracting it.)
In an essay for The Conversation, he says, ‘The outcome seems rather beautiful.
‘Negative masses are a hypothetical form of matter that would have a type of negative gravity – repelling all other material around them.
‘Unlike familiar positive mass matter, if a negative mass was pushed, it would accelerate towards you rather than away from you.
‘Negative masses are not a new idea in cosmology. Just like normal matter, negative mass particles would become more spread out as the universe expands – meaning that their repulsive force would become weaker over time.
‘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.’
Farnes believes that a powerful new telescope – the Square Kilometre Array – could be used to test his theory.
