So what about the other 95%?

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.

negative mass (repelling stuff around it, rather than attracting it.)

‘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.
