How Big is Our Universe?

Right now, light is racing toward you at six hundred and seventy million miles per hour from stars that died before Earth was born. You think you understand big... but what if everything you know about size is wrong? We're about to journey past neutron stars that spin faster than blender blades, through cosmic threads one billion light years long, and to places where space itself is being created faster than light can travel. If you're ready to have your mind blown by the true scale of existence, smash that like button because what comes next will change how you see everything. Prepare yourselves. We begin.
