From an article written by Nick Whigham:

The mysterious force known as dark energy is thought to be responsible for the runaway expansion of the universe but a new study suggests it could just be an illusion.

The still unexplained force is believed to make up about 68 per cent of the universe and has been put forth as an explanation as to why the universe continues to rapidly expand outwards at an accelerated rate, despite the force of gravity which pulls all matter together.

Astronomers in Hungary have conducted experiments which they say, could show how dark energy is not needed at all to describe this reality.

They argue that current cosmological models ignore the lumpy and inconsistent density of the universe where galaxies cluster together but instead use large-scale theories based on approximations where matter is assumed to have a uniform density when looking at the cosmos.
