There was a time, not so long ago, when science seemed to understand how the universe worked. Everything- us, the Earth, the stars and even exotic sounding supernovae- was made of atoms which were all created at time-zero: the Big Bang.
In between the atoms was nothing, a void: quite literally, 'space'.
But recently things have started to unravel. There is, it seems, a lot more to the universe than meets the eye. According to the best estimates, we only really know what about 4% of it is made of. But if only 4% is made of atoms what about the rest?
The rest is made of mysterious entities about which very little is understood with equally mysterious names: ‘dark matter’ and ‘dark energy’.
