The Big Bang isn't the start of everything? It appears that time had already existed before the Big Bang happened and physicists test the theory out in a new study.
Taking Einstein's famous equations at face value and making as few assumptions as possible, a team of researchers has rewound the clock on our Universe to find it wouldn't lead to a stopping point at all, but would take us through a different kind of beginning into a flipped space.
To understand what all the fuss over the Big Bang is, we need to rewind a bit to understand why physicists think it may not have been the start of everything.
Keep rewinding the clock – by around 13.8 billion years – and we get to a point where space has to be confined to an incredibly tiny volume, also known as a singularity.
