Why the Solar System Can Exist

The video explains why Earth doesn't spiral into the sun despite gravity's pull. It describes how the balance between gravitational attraction and speed keeps Earth in a stable orbit, similar to a marble in a bowl. This balance is unique to a three-dimensional universe, allowing stable orbits. The video also compares this concept to hyperbolic funnels, where objects eventually crash due to energy loss from friction.

What would happen if gravity were slightly steeper or tamer than it is in our universe?

How do hyperbolic funnels demonstrate the concept of stable orbits?
