We’ve come a long way in our understanding of dark energy. In previous episodes we’ve looked at how our universe is paradoxically flat and how dark energy is exponentially accelerating the expansion of the universe. In this episode of Space Time we dive into the true nature of dark energy and how its antigravity effect and its other properties are having such bizarre effects on our universe.
