The Big Bang theory has been challenged by a group of scientists who say the universe was formed when a four-dimensional star collapsed into a black hole.
Common understanding says the universe exploded from an infinitely dense point or singularity, but no one knows what triggered it. The theory proposes that the universe expanded faster than the speed of light.
The Big Bang theory also does not explain why temperatures across the universe are almost uniform – there would not be enough time since the Big Bang for the universe to reach a consistent temperature.
