What's Pushing the Universe Apart?

This film confronts dark energy, the mysterious force thought to be accelerating the expansion of the universe even though no one knows what it is. It gathers leading cosmologists as they explain the evidence, the competing theories, and why this puzzle sits at the heart of modern physics. Through clear explanation, it shows how a discovery can deepen a mystery rather than solve it. For anyone curious about the fate of the cosmos, it is an absorbing tour of the unknown.
