David Kipping Explains the True Scale of Our Universe

Our planet is a tiny speck of dust. Our galaxy is one of hundreds of billions. But what is the true scale of our universe? Is it finite, or does it stretch on into a mind-boggling infinity?

In this video, we journey to the edge of reality to answer the biggest question of all. We'll explain the crucial difference between the observable universe (the part we can see, which is 93 billion light-years across) and the mind-bending possibility that the total universe is vastly larger, perhaps even infinite.

This exploration is guided by the work of leading cosmologists and astronomers like David Kipping of the Cool Worlds lab, who uses evidence from the cosmic microwave background and the expansion of space to map our place in the cosmos. Prepare to feel very, very small.
