The wave structure of matter (WSM) model looks at the universe using only waves. As any useful model must, it explains many things that previously were puzzles or considered just weird such as the question of are they waves or are they particles, how particles attract and repel each other, how spacetime is shaped by matter and vice versa, the origin of the deBroglie wave, and more.
If you're new to all this then a good starting point is the article "The Wave Structure of Matter (WSM) and the Origin of Natural Laws" by Milo Wolff.

Q1 - Are there particles in the Wave Structure of Matter model?
Q2 - How does an in-wave come in from all directions? What is an in-wave?
