What is Quintessence? Well we know that something is up with the way the universe is expanding – there’s some kind of anti-gravitational effect that’s causing the expansion to accelerate. We don’t know what it is – just that it competes against the inward-pulling effect of gravity. And it’s winning – it looks like the universe will expand forever, at an ever-increasing rate. We call this mysterious influence dark energy, but while we’ve talked a lot about how it behaves, we’ve never really explored what it is. So, what is dark energy, really?

One strong possibility is quintessence. Quintessence is a hypothetical form of dark energy, more precisely a scalar field. Watch the episode to learn more.
