Gravitational forces are a key part of how our universe is formed, but figuring them out can be really tricky.

1. Complicated Interactions:

   • Gravitational pull works alongside other important forces (like magnetism and nuclear forces) which makes the universe feel chaotic.
   • It's hard to predict how large objects will behave and how they shape everything around them.

2. Scaling Challenges:

   • Galaxies and clusters of galaxies are so huge, making computer models and simulations difficult. This means we can’t always get exact answers.
   • We still don’t fully understand dark matter and dark energy, which adds even more confusion.

3. Possible Solutions:

   • Using advanced computer models and simulations could help us solve some of these problems.
   • Working together with different fields of study might lead to new ideas and ways to understand gravitational effects better.

In the end, gravitational forces play a huge role in how the universe is shaped. But, the complexities make it hard for us to fully understand them.
