The Other Side of a Black Hole

One of astronomy's great, enduring mysteries is what really happens on the inside of a black hole. We know that anything which gets too close to a black hole is destroyed, but if you were able to jump right inside of one, then what would happen and where would you go? Today, we will explore a few of the many exotic and fascinating possibilities for what lies on the other side of a black hole.

To give you a bit of context for this video, it is a remake / reboot of one of my oldest (and therefore worst) videos. Here it is if you would like to watch it, I will be unlisting it soon: https://youtu.be/L9L4S88MmpQ
