New model shows accelerated expansion can happen without dark energy

The study led by Eötvös Loránd University takes the changing structure of the universe into account, which it says conventional models fail to do. And, they found dark energy may not exist.

'Dark energy' thought to drive accelerated expansion, makes up 68% of cosmos
But, researchers say standard models don't account for structure of universe
In new model, they found acceleration can be explained without dark energy
They say model is consistent with present observations and general relativity



WHAT IS DARK ENERGY?
Dark energy is a phrase used by physicists to describe a mysterious 'something' that is causing unusual things to happen in the universe.

'The universe is not only expanding, but it is expanding faster and faster as time goes by,' Dr Kathy Romer, scientist at the Dark Energy Survey told MailOnline.

'What we'd expect is that the expansion would get slower and slower as time goes by, because it has been nearly 14 billion years since the Big Bang.'

Coming up with an equation of state would give the researchers clues about what is making up this mysterious force.
